Hello there!

3: (12 + x) ÷ 3 or [tex]\frac{12 + x}{3}[/tex]

1: $6.30

To solve 3, look at the parts of the question.

"The quotient of.." means you are dividing.

"12 increased by a number" means you are adding a certain number to 12, which can be modeled by 12 + x.

"Divided by 3" Means the previous phrase, or 12 + x, is being divided by 3.

You can model the equation as: (12 + x) ÷ 3 or [tex]\frac{12 + x}{3}[/tex].

To solve 1, find the unit rate for the cost per bag of ice.

$3.60 / 4 bags = $0.90 a bag.

Now, multiply the unit rate by the number you are trying to find (7).

$0.90 x 7 = $6.30. This is your final answer.

I hope this was helpful, and have a great rest of your day! If you need more help with these specific questions let me know in the comments! ~ Saturns

Number Three: y=12+x/3

Number One: $0.90(7bags)= $6.30 ***See explanation below**

To solve number one, you'd have to find the unit rate.

Since you pay $3.60 for every 4 bags, you have to find the price per bag.

$3.60 / 4 bags = $0.90

Now, since unit price is proportional, you'd multiply .90 by 7 bags.

$0.90(7bags)= $6.30.

(I'm bored sooo....)

Answer:

177 balls

Step-by-step explanation:

Let's start with the space we need for each sphere. If we approximate the value of the area to that of a cube that has the same dimensions of the diameter

[tex]V=H*W*D=0.8*0.8*0.8= 0.51 inches3

I can calculate the volume of the box as

[tex]V=H*W*D=3*4*7.5= 90 inches3

Finally I divide the volume of the box between the volume I need for each sphere Vt/Vs= 90/0.51 ≅ 177 balls

Answer:

The volume of the cylinder should be:

V = Bh = πr²h = 3.14 · 5² · 10 = 785 (mm³)

The volume of the sphere should be:

V = 4/3 · πr³ = 4/3 · 3.14 · 5² ≈ 523.33 (mm³)

=> The total volume of the composite figure is:

V = 785 + 523.33 = 1,308.33 (mm³)

Answer:

V = 785 + 523.33 = 1,308.33 (mm³)

Answer: There are two answers to this x=3 and x=11

Step-by-step explanation:

Answer:  The correct option is (A). x = 3.

Step-by-step explanation:  We are given to find the solution of the following quadratic equation :

[tex](x-2)(x+10)=13.[/tex]

We have

[tex](x-2)(x+10)=13\\\\\Rightarrow x^2-2x+10x-20=13\\\\\Rightarrow x^2+8x-20-13=0\\\\\Rightarrow x^2+8x-33=0\\\\\Rightarrow x^2+11x-3x-33=0\\\\\Rightarrow x(x+11)-3(x+11)=0\\\\\Rightarrow (x-3)(x+11)=0\\\\\Rightarrow x-3=0,~~~x+11=0\\\\\Rightarrow x=3, -11.[/tex]

So, the solution of the given equation is x = 3 and x = -11.

Thus, the correct option is (A). x = 3.

Answer:

3

Step-by-step explanation:

y = -9 when x = 3

When x = -4.5, the first definition of the function will be used since -4.5 is less than -3. In this region, y = -x implying that when x = -4.5,  y= 4.5.

When x = 3, the last definition of the function will be used since 3 is greater than -2. In this region, y = -x^2 implying that when x = 3,  y= -9.

Answer:

The company's assets are 535,000.00.

Step-by-step explanation:

To find the company assets we can use the formula:

Assets = Liabilities + Equity

In the given question,

Liabilities = 195,000.00

Equity = 340,000.00

Putting values in the above formula:

Assets = Liabilities + Equity

Assets = 195,000.00 + 340,000.00

Assets = 535,000.00

So, the company's assets are 535,000.00.

Answer:

the answer is C

Step-by-step explanation:

if there are 3 cups and he put seven in each then multiply 7 by 3 and you get 21 then take 3 away and you have 18

Carmen has 18 counters left.

To find out how many counters Carmen has left, we need to subtract the number of counters taken by Abe from the initial number of counters Carmen had.

Carmen initially had 7 counters in each of the 3 cups, so she had a total of 7 x 3 = 21 counters.

Abe took 3 counters, so we subtract 3 from 21 to find that Carmen has 18 counters left.

Therefore, option C, 18, is the correct answer.

The total profit of Vic for the five days of sales given the cost of ingredients and fuel is £874.60.

Total profit is the total revenue less total cost.

Total revenue = 225 + 260 + 230 + 180 + 150 = £1045

Cost of ingredients = 12% x 1045 = $125.40

Total fuel = £9 x 5 = £45

For this case we must find an expression equivalent to:

[tex]\frac {\sqrt [7] {x ^ 2}} {\sqrt [5] {y ^ 3}}[/tex]

By definition of properties of powers and roots we have:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

So, rewriting the expression we have:

[tex]\frac {x ^ {\frac {2} {7}}} {y ^ {\frac {3} {5}}} =[/tex]

By definition of power properties we have:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

So:

[tex]x ^ {\frac {2} {7}} * y ^ {- \frac {3} {5}}[/tex]

(√x²/⁷)(√y⁵/³)

Step-by-step explanation:

Points to remember

Identities

Xᵃ * Xᵇ = x⁽ᵃ⁺ᵇ⁾

Xᵃ/Xᵇ = X⁽ᵃ⁻ᵇ⁾

1/Xᵃ = X⁻ᵃ

X¹/ᵃ = 1/Xᵃ

To find the correct option

From the figure we can see that,

7√x²/5√y³

Using identities we can write,

7√x²/5√y³ = (√x²/⁷)/(√y³/⁵

 =  (√x²/⁷) * (√y⁵/³)

Therefore the correct answer is second option

(√x²/⁷)(√y⁵/³)

well, the difference is just 6300 - 5600 = 700.

if we take 5600 to be the 100%, what is 700 off of it in percentage?

[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 5600&100\\ 700&x \end{array}\implies \cfrac{5600}{700}=\cfrac{100}{x}\implies 8=\cfrac{100}{x} \\\\\\ 8x=100\implies x=\cfrac{100}{8}\implies x=\cfrac{25}{2}\implies x=12.5[/tex]

Final answer:

Brandy's mistake was not converting the diameter to the radius before applying the area formula A = πr². The correct area of a circle with a diameter of 12 cm is 113.04 cm², but it should be reported as 110 cm² to maintain two significant figures.

Explanation:

The error in Brandy's solution for finding the area of a circle with a diameter of 12 cm lies in not first converting the diameter into the radius. The formula for the area of a circle is A = πr², where r is the radius and π (pi) is approximately 3.14. Since the radius is half of the diameter, for a diameter of 12 cm, the radius is 6 cm. Thus, the correct calculation is A = 3.14 × 6².

Correct solution:

A = 3.14 × 6 cm²

A = 3.14 × 36 cm²

A = 113.04 cm²

As for the significance of figures, since the radius has two significant figures (6 cm), the calculated area should also be limited to two significant figures, rounding to 110 cm².

Answer: X is equal to 162

Step-by-step explanation:

You multiply the result of -18 by the -9 because these two would equal the number for X.

Negative times a negative is a positive.

Answer: 162

Equation: x / -9 = -18

Multiply both sides by -9

x / -9( -9 ) = ( -18 )( -9 )

Simplify (Multiply -18 by -9)

x = 162

8,076 ....................

Answer:

8076

Step-by-step explanation:

You need a 4-digit number. The leftmost digit is the thousands digit (T). The next digit to the right is the hundreds digit (H). The third digit from the left is the tens digit (E), and the rightmost digit is the ones digit (O).

Using T, H, E, and O, as shown above, the number will have the form:

THEO

Now you replace each letter with the correct digit.

"eight thousand, seventy-six" has no hundreds, so let's include hundreds:

"eight thousand (T = 8), zero hundreds (H = 0), and seventy (E= 7)-six (O = 6)"

8076

The important thing is to remember to include a 0 as the digit for the hundreds place.

Answer:

14

Step-by-step explanation:

The interquartile range is the value of quartile 3 minus quartile 1.

The "box" part of this diagram has 3 lines, the left most, the middle, and the rightmost.

The leftmost line is Quartile 1. The right most is Quartile 3.

Hence

interquartile range = quartile 3 - quartile 1

Looking at the box plot, we can see that each small line in the number line is 2 units.

The leftmost line (quartile 1 ) is at 1 unit left of 30, so that is 30 -2 = 28

The rightmost line (quartile 3) is at  1 unit right of 40, so that is 40 + 2 = 42

Hence,

Interquartile range = 42 - 28 = 14

Answer:

c: 14

Step-by-step explanation:

I see everyone saying it is B or D, but ITS C! The graph is counting by 2, so there fore it is 42-28= 14. :)

Answer:

The constant of variation is

[tex]k= 5[/tex]

Step-by-step explanation:

First we must write the relationship as an equality.

If q varies inversely with the square of m, this means that when m ^ 2 increases then q decreases.

If q varies directly with the product of r and x this means that when r * x increases q increases.

Then the relationship is:

[tex]q = k\frac{rx}{m^2}[/tex]

Where k is the constant of proportionality

Then if:

[tex]q=2.5\\\\m=4\\\\r*x=8[/tex]

[tex]2.5 = k\frac{8}{4^2}[/tex]

We solve for k

[tex]2.5 = k\frac{8}{16}[/tex]

[tex]2.5 = k\frac{1}{2}[/tex]

[tex]k= 5[/tex]

Answer:

[tex]a =111.1\ m/s^2[/tex]

Step-by-step explanation:

The formula to calculate the average acceleration is:

[tex]a =\frac{s_2-s_1}{t_2-t_1}[/tex]

Where s is the speed of the object and t is the time it takes the object to change its speed [tex]s_1[/tex] to the speed [tex]s_2[/tex]

In this case we have that:

[tex]t_2-t_1 = 5\ sec[/tex]

[tex]s_1 = 500\ km/h = 500*\frac{1\ h}{3600\ s}*\frac{1000\ m}{1\ km}=138.89\ m/s[/tex]

[tex]s_2= 2500\ km/h = 2500*\frac{1\ h}{3600\ s}*\frac{1000\ m}{1\ km}=694.44\ m/s[/tex]

[tex]a =\frac{694.44-138.89}{5}\ m/s^2[/tex]

[tex]a =111.1\ m/s^2[/tex]

The minimum  happens at x = -b/2a

x = -30 / 2(3) = -30/6 = -5

Now replace x in the equation with -5 and solve:

3(-5)^2 + 30(-5) +27 = 75 - 150 + 27 = -48

The minimum is at (-5,-48)

The min is x= -b/2a

X=-30/2(3)

-30/6= -5

Answer:

10 square units

Step-by-step explanation:

We want to find the area under the curve [tex]f(x)=x+3[/tex] from x=1 to x=3.

We use definite integrals to find this area.

[tex]\int\limits^3_1 {x+3} \, dx[/tex]

We integrate to obtain:

[tex]\frac{x^2}{2}+3x|_1^3[/tex]

We evaluate the limits to get:

[tex]\frac{3^2}{2}+3(3)-(\frac{1^2}{2}+3(1))[/tex]

[tex]4.5+9-0.5-3=10[/tex]

Therefore the area under the curve from x=1 to x=3 is 10 square unit.

Answer:

6=n   and -2=n

Step-by-step explanation:

The distance between two points is found by

d = sqrt(( x2-x1)^2 + (y2-y1)^2)

5 = sqrt(( n-2)^2 + (4-1)^2)

5 = sqrt(( n-2)^2 + (3)^2)

Square each side

5^2 = sqrt(( n-2)^2 + (3)^2)^2

25 = ( n-2)^2 + (3)^2

25 = (n-2)^2 +9

Subtract 9 from each side

25-9 = (n-2)^2 +9-9

16 = (n-2)^2

Take the square root of each side

sqrt(16) = sqrt( (n-2)^2)

±4 = n-2

Add 2 to each side

2±4 = n-2+2

2 ±4 = n

2+4 =n   and   2-4 =n

6=n   and -2=n
