What is a better buy? Store A: $1.50 for 5 oz or Store B: $1.20 for 3 oz
And please explain, I really need help!

Answers

Answer 1
Store A would be better because ultimately, you get more for less. If you wanted 5 oz from Store B, it would be $2.00 ( 1.20/3 = 0.4. 0.4 x 5 = 2 ), which is more than Store A.
Answer 2

Answer:

Store A is the better buy.

Step-by-step explanation:

The first thing I did was to find a multiple that 3 and 5 share which is 15. Now, we can figure out how much each store charges for 15 oz. I put the numbers into fraction form to make it easier. 5/1.50 and 3/1.20. To get 5 to 15, I multiplied it by 3, so I also have to do that to 1.50. This leaves me with 4.50. Store A charges 4.50 for 15 oz. Next, we have to go over to the other fraction. To get 3 to 15, I multiplied it by 5. Whatever you do to the numerator, you have to do to the denominator, so you multiply 1.20 by 5. This gets you 6. Store B charges 6 dollars for 15oz, so store A has a better price. I hope this helps.

Write the equation of the line with a slope of 5 and the point (2, 6) in slope-intercept form

Answers

Answer:

y = 5x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5, thus

y = 5x + c ← is the partial equation

To find c substitute (2, 6) into the partial equation

6 = 10 + c ⇒ c = 6 - 10 = - 4

y = 5x - 4 ← equation of line

A pizza restaurant charges a flat fee for a plain cheese pizza. There is an extra charge for any additional toppings. The cost of a pizza can be I determined from the equation C = 0.5m + 5, where m is the number of
additional toppings and C is the cost of the pizza ordered. What are the
interpretations of slope and y-intercept in the equation?
A
slope: cost per additional topping
y-intercept: cost of the plain pizza
B. slope: cost per additional topping
y-intercept: cost of the first topping
C. slope: cost of the plain pizza
y-intercept: cost per additional topping
D. slope: ratio of cost of additional topping to the cost of the plain pizza
y-intercept: cost of an additional topping

Answers

The slope of 0.5 represents the cost per additional topping, while the y-intercept of 5 represents the cost of the plain pizza. Option A provides the correct interpretations.

To interpret the slope and y-intercept of the equation C = 0.5m + 5, where  C  represents the cost of the pizza and m represents the number of additional toppings:

A. The correct interpretation is:

- Slope: The slope of 0.5 represents the cost per additional topping. This means that for each additional topping added to the pizza, the cost increases by $0.5.  

- Y-intercept: The y-intercept of 5 represents the cost of the plain pizza without any additional toppings. This is because when m = 0 (no additional toppings), the cost of the pizza is $5, which is the flat fee for the plain cheese pizza.

To confirm:

- When m = 0, the equation becomes C = 0.5(0) + 5 = 5 , which is the cost of the plain pizza without any additional toppings.

- When m = 1, the equation becomes C = 0.5(1) + 5 = 5.5, indicating that the cost increases by $0.5 when one additional topping is added.

Therefore, option A correctly interprets the slope and y-intercept of the equation.

Nivyana and Ana are selling their apparel to earn money for a cruise. Knitted scarves are $50, and mittens are $25 per pair. They cannot make more than 30 scarves and mittens combined. They need to earn at least $1000 to pay for the cruise and souvenirs.


Part A:Write the inequalities that would represent the situation

Part B: GRAPH the system of linear inequalities and shade where the solutions are.

Part C: Identify two possible solutions to Nivyana and Ana's situation

--------- scarves ------------scarves

---------------mittens -----------mittens

Answers

Step-by-step explanation:

Part A:

Let [tex]m[/tex] be the number of mittens and [tex]s[/tex] be the number of scarves. Then we have the inequalities:

[tex]s+m\leq 30.[/tex] This says Nivyana and Ana cannot make more than 30 scarves

[tex]50s+25m\geq 1000.[/tex] This says that Nivyana and Ana have to earn at least $1000.

Part B:

The graph is attached.

Notice that the graphs of the inequalities are solid lines, this just means that the points on these lines included to the solutions of each inequality.

The darker shaded region and the solid lines bounding it, are the solutions to the inequalities because that's where the values common to both inequalities are found.

Part C:

From the graph we get two possible solutions:

15 scarves & 10 mittens

25 scarves & 5 mittens.

These two points lie on the solid lines that bound the darker shaded region (I picked those points to stress that the lines bounding the dark region are also solutions.)

A professor wants to randomly select 4 students to go to the board. She decides to randomly select the fourth student who enters the classroom and every ninth student after that. Determine the students who will be going to the board. Write down the student numbers.

Answers

Final answer:

To determine the students selected to go to the board, start with the fourth student and then select every ninth student thereafter. Thus, the students chosen are the 4th, 13th, 22nd, and 31st students who enter the classroom.

Explanation:

The question involves determining which students a professor will select to go to the board based on a specific selection process. The professor decides to randomly select the fourth student who enters the classroom and every ninth student after that. To find out who these students are, we begin by identifying the fourth student initially. After the fourth student, every ninth student subsequently means we add 9 to the initial student's number to find the next student.

The fourth student who enters

The fourth student + 9 = the 13th student

The 13th student + 9 = the 22nd student

The 22nd student + 9 = the 31st student

Therefore, the students selected to go to the board are the 4th, 13th, 22nd, and 31st students who enter the classroom.

The students who will be going to the board are students 4, 9, 18, and 27.

Let’s determine the students who will be going to the board based on the professor’s selection criteria:

1. The fourth student who enters the classroom.

2. Every ninth student after that.

Let’s find the student numbers:

1. The fourth student corresponds to the 4th position.

2. The ninth student corresponds to the 9th position.

3. The 18th student corresponds to the ninth student after that (since 9 + 9 = 18).

4. The 27th student corresponds to the ninth student after the 18th student (since 18 + 9 = 27).

Therefore, the students who will be going to the board are students 4, 9, 18, and 27.

What point is interected between 10x-3y=19 and 5x+4y=-7

Answers

Answer:

(1, -3)

Step-by-step explanation:

Solve the system of equations of the two lines:

10x-3y=19 ------> eq 1

5x+4y=-7 --------> eq 2

Solve by elimination:

eq 2 x 2

2( 5x+4y) = 2(-7 )

10x + 8y = - 14 ------> eq 3

eq3 - eq 1:

(10x + 8y) - (10x-3y) = - 14 - 19

10x + 8y - 10x + 3y = -33

8y + 3y = -33

11y = -33

y = -3  (substitute back into eq 1)

10x - 3y = 19

10x - 3(-3) = 19

10x + 9 = 19

10x  = 19 - 9

10x = 10

x = 1

Hence the intersection point is (1, -3)

Rollie was successful in losing weight. He had a goal

weight in mind. He went on a diet for three months. Each

month, he would lose one-third of the difference between

his current weight and his goal weight and an additional

three pounds. At the end of three months, he was just 3

pounds over his goal weight. How many pounds did he

lose in those three months?

Explain how you arrived at your solution.

Answers

Answer:

If X is the starting weight, total pounds lost in three months is

(0.132X + 2.37)lbs

Step-by-step explanation:

Let the starting weight be X(lb)

Let the target ending weight be Y(lb)

Since Rollie ended with 3(lbs) above goal weight, final weight is Y+3(lb)

Each month, Rollie lost 1/3 of the difference between current weight and goal weight, hence

In the first month, Rollie lost 1/3 of (X - Y)

but since Rollie ended up with 3lbs above target ending weight, the actual weight loss is 1/3(X - Y) + 3

Hence  by the end of the first month, Rollie's new weight is X - (1/3(X - Y)) + 3

which is equal to

X - 1/3X + 1/3Y - 3.

= 2/3X + 1/3Y - 3

By the second month, Rollie's starting weight is 2/3X + 1/3Y - 3(lb)

while her target ending weight still remains (Y)

but the actual ending weight is Y + 3

hence in the second month, Rollie lost 1/3(2/3X + 1/3Y - 3 - Y) + 3

= 2/9X + 1/9Y - 1 - 1/3Y + 3

=  2/9X - 2/9Y + 2

hence by the end of the second month, Rollie's new weight is

(2/3X + 1/3Y - 3) - (2/9X - 2/9Y + 2)

= 2/3X - 2/9X + 1/3Y + 2/9Y - 3 - 2

= 4/9X + 5/9Y - 5  

By the third month, Rollie's starting weight is 4/9X + 5/9Y - 5(lb)

while her target ending weight still remains (Y)

but the actual ending weight is Y + 3

hence in the third month, Rollie lost 1/3(4/9X + 5/9Y - 5 - Y) + 3

= 4/27X + 5/27Y - 5/3 - 1/3Y + 3

= 4/27X - 4/27Y + 4/3 ------------------------- eqn (*)

hence by the end of the third month, Rollie's new weight is

(4/9X + 5/9Y - 5) - (4/27X - 4/27Y + 4/3)

= 4/9X - 4/27X + 5/9Y + 4/27Y - 5 - 4/3

= 8/27X - 19/27Y - 19/3

Hence in three months, Rollie's new weight is 8/27X - 19/27Y - 19/3

To ascertain how much weight Rollie lost in three months, there is need to equate the estimated ending weight to the final weight (Y + 3)

Therefore:

8/27X - 19/27Y - 19/3 = Y + 3

this implies that

8/27X - 19/27Y - Y - 19/3 - 3 = 0

8/27X - 36/27Y -28/3 = 0

Since Y is the target ending weight

the ending weight is generated by solving the equation with respect to Y

36/27Y = 8/27X - 28/3

multiply through by 27/36

Y = 2/9X - 7

Hence weight lost in three months is generated by substituting for Y = 2/9X - 7  in eqn (*)

Since eqn * is 4/27X - 4/27Y + 4/3

the lbs lost in three months is

4/27X - 4/27(2/9X - 7 ) + 4/3

= 4/27X - 8/243X + 28/27 + 4/3

= (32/243)X + 64/27

which in decimal is

(0.132X + 2.37)lbs

The total pounds of weight that will be lost in three months will be (0.132x + 2.37)lbs.

How to compute the weight?

The starting weight is illustrated by x. The target ending weight is illustrated by y.

In the first month, the weight list by Rollie will be 1/3 × (x - y) and her new weight will be:

= 2/3x + 1/3y - 3

In the second month, the starting weight will be 2/3x + 1/3y - 3. The weight lost by the end of the second month will be:

= 1/3 × (2/3x + 1/3y - 3) + 3

= 2/9x - 2/9y + 2

The new weight will be:

= (2/3x + 1/3y - 3) - (2/9x - 2/9y + 2)

= 4/9x + 5/9y - 5

In conclusion, the weight lost in three months will be:

= 4/27x - 4/27(2/9x - 7) + 4/3

= 4/27x - 8/243x + 28/27 + 4/3

= 32/343x + 64/27

= 0.132x + 2.37

In conclusion, the total pounds of weight that will be lost in three months will be (0.132x + 2.37)lbs.

$1,650.25
$1,626.00
$1,745.70
$1,554.80

Answers

Option C

Total amount paid by Alberto is $ 1745.7

Solution:

Given that Alberto paid for seven large tables to be delivered to the restaurant

Alberto paid a delivery fee of  $95.45

Cost of 1 table = $ 235.75

To find: total amount Alberto paid

cost of seven tables = cost of 1 table x 7

[tex]\text {cost of seven tables }=235.75 \times 7=1650.25[/tex]

Total amount paid = cost of seven tables + delivery fee

Total amount paid = 1650.25 + 95.45

Total amount paid = 1745.7

Thus total amount paid by Alberto is $ 1745.7 Therefore option C is correct

I assume you mean this:

[tex]8 \frac{7}{8} +(7 \frac{5}{6} -2\frac{1}{3} )[/tex]

Lets begin with the parentheses. When operating with fractions, we need them to have the same denominator. Looking at the expression in the parenthesis, we can see that the denominator of 5/6, that being 6, is twice that of 1/3, that being 3. Thus, if we multiply the numerator and denominator of 1/3 by 2, the result will be a fraction of same value, but with denominator 6, which we can work with.

[tex]\frac{1*2}{3*2}[/tex]

[tex]\frac{2}{6}[/tex]

Now we can replace this in the original parenthesis

[tex](7 \frac{5}{6} -2\frac{2}{6})[/tex]

We can now evaluate the parenthesis. 7-2=5, which leaves us with 5 5/6 - 2/6. Since the two fractions have the same denominator, we can subtract the numerator of 2/6 from 5/6. This gives us with 3/6, which we add to the 5 from before.

[tex]5\frac{3}{6}[/tex]

The numerator and denominator of 3/6 are both divisible by three, so we can simply the fraction.

[tex]5\frac{1}{2}[/tex]

Now that we have solved the parenthesis, we can plug our solution back into the original expression.

[tex]8 \frac{7}{8} +5\frac{1}{2}[/tex]

We now have a similar problem to the parenthesis, where our fractions have different denominators. However, you may notice that the denominator of 7/8 (8) is four times larger than the denominator of 1/2 (2). Thus, if we multiply the numerator and denominator of 1/2 by four, we will have a new fraction of equal value, but with denominator 8.

[tex]\frac{1*4}{2*4}[/tex]

[tex]\frac{4}{8}[/tex]

Now lets update our expression with this information.

[tex]8 \frac{7}{8} +5 \frac{4}{8}[/tex]

8+5=13[tex]13\frac{7}{8} +\frac{4}{8}[/tex], so we can further simplify the expression.

Since the denominators of the fractions are the same, we can combine the numerators. 7+4=11

[tex]13 \frac{11}{8}[/tex]

We can simplify the fraction by taking one whole out of it (8/8) and adding it as 1 instead. 11-8=3, thus the fraction that remains is 3/8.

[tex]14 \frac{3}{8}[/tex]

Final answer:

The operation 8 7/8+(7 5/6-2 1/3) evaluates to a final result of 14 3/8.

Explanation:

To evaluate this mixed number operation, we must first convert each mixed number into an improper fraction.

8 7/8 is the same as 71/8 and 7 5/6 as 47/6 and 2 1/3 as 7/3.

Now, conduct the operation inside the parenthesis, which is subtraction: 47/6 - 7/3.

To subtract fractions, they must have the same denominator. Here, the least common multiple of 3 and 6 is 6. So you have 47/6 - 14/6 equals 33/6 reduced to 5 1/2.

Then add this quantity to 8 7/8 which equals to 14 3/8 when converted to a mixed number.

Answer:

∠Q = 75 °

Step-by-step explanation:

Since PR = PQ then Δ PQR is isosceles and the base angles are congruent, that is

∠R = ∠Q = 2x + 15

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

2x + 15 + 2x + 15 + x = 180, that is

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30

Hence

∠Q = 2x + 15 = (2 × 30) + 15 = 60 + 15 = 75°

Final answer:

To find the product of the given expression (7x²)(2x + 5)(x² - 4x-9), we can use the distributive property to multiply each term.

Explanation:

To find the product of the given expression (7x²)(2x + 5)(x² - 4x-9), we can use the distributive property to multiply each term.

First, multiply (2x + 5) with (x² - 4x-9) using the distributive property.
(2x + 5)(x² - 4x-9) = 2x*(x² - 4x-9) + 5*(x² - 4x-9)
= 2x³ - 8x² - 18x + 5x² - 20x-45
= 2x³ - 3x² - 38x - 45

Answer:

32

Step-by-step explanation:

Subtract 4 from 100

96

Divide by 3

32

Final answer:

The solution to the equation is x = 32, so Elijah baked 32 brownies last week.

Explanation:

To find out how many brownies Elijah baked last week, we need to solve the equation 100 = 4 + 3x, where x is the number of brownies he made last week. Here are the steps to solve the equation:

Subtract 4 from both sides of the equation: 100 - 4 = 3xSimplify: 96 = 3xDivide both sides of the equation by 3: 96 ÷ 3 = xCalculate the result: x = 32

Therefore, Elijah baked 32 brownies last week.
