A produce store offers red and green apple. In one morning they sold 77 apples total. If 7 of the apples they sold were red, what is the ratio of green apples sold to red apples apples sold?​

Answer:

y=80x+50 for the one time service fee.

Anytime after that would be y=80x

Step-by-step explanation:

Y is how much the total is and 80 is how much it is an hour. X is the number of hours worked. With the first time fee of $50, your equation would be y=80x+50. Anytime after that, excluding the “one time fee,” the equation would be y=80x.

Answer:

Step-by-step explanation:

f(x)=2x^2-8x+9

Find -b/2a first, it's -(-8)/2(2)=8/4=2.

Then find the y-coordinate of the vertex.

2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1

Answer:

R= {y|y>=1}

Step-by-step explanation:

D = all real numbers R= {y|y>=1}.

All polynomials have domain of all real numbers.

For the range, the vertex format is useful;

Y= (X-1)^2 + 1

Since (X-1) is never less than zero, Y>=1.

That is where the vertex is, at Y=1

Answer:

hence small rolls 60 and large rolls 70

Step-by-step explanation:

let club sold s small rolls

hence club sold s+10 large  rolls

earning from small roll 3s

earning from large rolls 4.5(s+10)

hence

4.5(s+10) - 3s  = 135

or  4.5(s+10) = 3s +135

3s +135 = 4.5(s+10)

3s +135 = 4.5s +45

4.5s +45 = 3s +135

4.5s -3s = 135-45

1.5s = 90

s = 90/1.5

s= 60

s+10 = 70

hence small rolls 60 and large rolls 70

The history club sold 60 small rolls of wrapping paper according to the given equation.

The subject here is Mathematics, specifically algebra. The equation given by the problem, 3S + 135 = 4.5(S + 10), can be solved to find 'S', which represents the number of small rolls sold by the history club. Start by distributing the 4.5 across the (S + 10) on the right side of the equation. This gives 3S + 135 = 4.5S + 45. Subtract 3S from both sides of the equation to get 135 = 1.5S + 45. Subtracting 45 from both sides then gives 90 = 1.5S. Finally, divide each side of the equation by 1.5 to get S = 60. So, the history club sold 60 small rolls.

You can visit at most 10 swim classes.

Step-by-step explanation:

Let x be the number of swim classes you can attend with.

At your local pool, it costs $50 to join the swim association and $5 for each swim class. then x classes cost $5x and the total cost is $(50 + 5x).

You have budgeted $100 to improve your swimming over the summer. Hence,

[tex]50+5x\le 100[/tex]

Solve this inequality:

[tex]50+5x-50\le 100-50\\ \\5x\le 50\\ \\x\le 10[/tex]

You can visit at most 10 swim classes.

The student can join the swim association and attend up to 10 swim classes within the $100 budget.

This question is asking for the creation and solution of an inequality based on a budgeting scenario. The student has budgeted $100 and needs to spend $50 to join the swim association, leaving $50 for swim classes at $5 each. The problem can be represented by the inequality 5c ≤ 50, where c is the number of swim classes.

To solve the inequality, you would divide both sides by 5. The solution of this inequality is c ≤ 10. So, the student can attend up to 10 swim classes within the budget.

Answer: 41/100

Step-by-step explanation: First, we can change .41 to 0.41 by putting a zero in front of the decimal point.

Using the place value chart, we can see that 0.41 means 0 units, 4 tenths a 1 hundreth. Think of 4 tenths and 1 hundredth as 41/100 so we have 41/100.

Since the fraction 41/100 is in lowest terms, this is our final answer.

Lily has saved $ 7

Solution:

Given that bracelet costs $30

The bracelet Lily would like to buy costs $5 less than 5 times the amount she has saved

Cost of bracelet = $ 30

From given statement,

Cost of bracelet = 5 times the amount she has saved - 5

Let "x" be the amount saved by lily

Cost of bracelet = 5 times x - 5

Here "times" represents multiplication

30 = 5(x) - 5

30 = 5x - 5

30 + 5 = 5x

5x = 35

On dividing 35 by 5 we get 7

x = 7

Thus Lily saved $ 7

Answer:

1.  Start with the cost of the bracelet: 30.

2. Add 5: 30 + 5 = 35.

3. Divide by 5: 35 / 5 = 7

Answer:

the line 1 has negative slope of -1/4 and line 2 has positive slope of 1/4.

Step-by-step explanation:

let the line 1 be y = -1/4x + 2 and line 2 be 2y = 1/2x - 4

these lines are in the form of y = mx + c

where m is the slope of the line and c is the  intercept made with y axis.

dividing the line 2 by 2 we get [tex]y = \frac{1}{4}x -2[/tex]

line 1 meets x axis when y = 0 applying y = 0 in equation 1 we get x = 8

line 2 meets x axis when y=0 applying y = 0 in equation 2 we get x = 8

line 1 meets y axis when x = 0 applying x= 0in equation 1 we get y = 2

line 2 meets y axis when x = 0 applying x= 0in equation 2 we get y = -2

therefore line 1 passes through (8,0)and (0,2) with negative slope of -1/4

and line 2 passes through (8,0) and (0,-2) with positive slope of 1/4.

Answer:

B. [tex]x=-210[/tex]

D. [tex]x=-201[/tex]

Step-by-step explanation:

Given:

The inequality for 'x' is given as:

[tex]x<-200[/tex]

The above inequality tells us that, the value of the variable 'x' is less than -200.

-200 is a negative number. So, for a negative number, the larger the value of the number, the smaller the number is.

Example: -2 is less than -1 although 2 has a greater magnitude than 1.

Therefore, the numbers that are less than -200 are -210 and -201.

So, the values of 'x' that satisfy the given inequality are -201 and -210

Thus, the correct options are (B) and (D).

Answer:

Ans => 45

Step-by-step explanation:

3(d+1) = 4(d-2)

Expanding the brackets we have:

3d + 3 = 4d - 8

our aim now is to solve for d

3d - 4d = -8 - 3

-d = -11

=> d = 11

we can now get 5(d-2)

substituting d = 11

5(11-2)

5(9)

= 45

The value of 5(d-2) is 45.

3(d+1)=4(d–2)

3d + 3 = 4d - 8.

3d - 4d = -8 - 3.

-d = -11

d = 11

Substitute d = 11 into 5(d–2):

5(d-2)=5(11-2)

= 5(9)

= 45.

Final answer:

Gary spends approximately 54.29% of his free time on video games and the internet.

Explanation:

To find the percentage of free time that Gary spends on video games and the internet, we need to calculate the total number of hours he spends on these activities and divide it by the total number of hours of free time he has.

First, calculate the total number of hours Gary spends on video games and the internet: 10 + 9 = 19 hours.

Next, calculate the total number of hours Gary has for free time in a week: 5 hours per day x 7 days = 35 hours.

To find the percentage, divide the total number of hours spent on video games and the internet by the total number of hours of free time and multiply by 100: (19 / 35) x 100 = 54.29%.

Therefore, Gary spends approximately 54.29% of his free time on video games and the internet.

To find the percentage of free time that Gary is using to play video games and use the internet, calculate the total free time and the proportion of time spent on video games and internet use.

To find the percentage of free time that Gary is using to play video games and use the internet, we need to calculate the total amount of free time Gary has and then determine the proportion of that time spent on video games and internet use.

Gary spends 10 hours per week on the internet and 9 hours per week on video games. This is a total of 10 + 9 = 19 hours per week.

Since Gary has 5 hours of free time per day, he has a total of 5 * 7 = 35 hours of free time per week.

To find the percentage, we divide the time spent on video games and internet use (19 hours) by the total free time (35 hours) and then multiply by 100. So, the percentage is (19/35) * 100 = 54.28% (rounded to two decimal places).

Full bottle = 6.8 x 5 = 34 ounces

water remain in bottle = 34 -6.8 = 27.2 ounces

There is 34 ounces of water in the bottle initially and this can be determined by using the unitary method.

Given :

The following steps can be used in order to determine the total amount of water in the full bottle:

Step 1 - The unitary method can be used in order to determine the total amount of water in the full bottle.

Step 2 - According to the given data, Diego pours 6.8 ounces of water from a full bottle which is the 20% of the water in the bottle.

Step 3 - If 20% is 6.8 ounces of water than the 100% is given by:

[tex]=\dfrac{6.8}{20}\times 100[/tex]

Multiply 6.8 by 100 in the above expression.

[tex]=\dfrac{680}{20}[/tex]

Divide 680 by 20 in the above expression.

= 34 ounces

So, there is 34 ounces of water in the bottle initially.

Answer:

The length of the carpet = l = 5 meter  

The cost of carpeting the room is Rs 6300  .

Step-by-step explanation:

Given as :

The area of the room = 45 m²

The width of the carpet = w = 9 m

Let The length of the carpet = l meter

The cost of the carpet per meter = Rs 225

Let The cost of carpeting the room = Rs x

Now, According to question

The Area of room = length × breadth

Or, 45 m² = l m × b m

Or,  45 m² = l m × 9 m

∴  l = [tex]\dfrac{45}{9}[/tex]

i.e l = 5 m

So, The length of the carpet = l = 5 meter

Again

Perimeter of carpet = 2 × length + 2 × width

Or, Perimeter of carpet = 2 × 5 m + 2 × 9 m

Or, Perimeter of carpet = 28 meters

∵ The cost of carpet per meter = Rs 225

∴ The cost of carpeting the room = Rs 225 × 28

i.e The cost of carpeting the room = Rs 6300

Hence, The length of the carpet = l = 5 meter and The cost of carpeting the room is Rs 6300  . Answer

Answer:

4/3

Step-by-step explanation:

(1/3)/(1/4)

(1/3)(4/1)

4/3

The ratio 1/3:1/4 is simplified to 4:3 by finding a common denominator. In the given proportion with a scale factor, cross-multiplication is used to find the actual dimension which results in x=8 when the scale dimension is 4.

To express the ratio 1/3:1/4 in its simplest form, find a common denominator for the two fractions, which in this case is 12. The fraction 1/3 is equivalent to 4/12, and 1/4 is equivalent to 3/12. Therefore, the ratio 1/3:1/4 becomes 4/12:3/12. Since both denominators are the same, they can be canceled out, leaving us with the simplified ratio 4:3.

Now, let's apply this to a problem with a scale factor. For the proportion 1:2=4:x, to find the value of x, you can cross-multiply. This gives us 1*x = 2*4 which simplifies to x=8. Therefore, if the scale dimension is 4, the actual dimension is 8.
