A store has apples on sale at $3.00 for 2 pounds.

sergeinik [125]

5 ounces × 24 apples= 120 ounces of apples

1 pound= 16 ounces

120 ounces = 7.5 pounds

$3 = 2 pounds

$11.25 = 7.5 pounds.

You cannot but 24 apples for $9 because each apple is five ounces, so you multiply each apple by its weight, and get 120 ounces. Since there is 16 ounces in 1 pound, you have 7.5 pounds of apples. If 2 pounds is three dollars then 7.5 can't be nine.

Brianna and Ava go to the movie theater and purchase refreshments for their friends. Brianna spends a total of $39.00 on 2 bags

kirill [66]

Answer:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Price of one drink is $9.25

Step-by-step explanation:

Let the price of a bag of popcorn be p.

Let the price of a drink be d.

Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. This implies that:

2p + 2d = 39 ____________(1)

Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. This implies that:

8p + 10d = 174.50 _________(2)

We now have two system of equations which we can use to find the price of a bag of popcorn and drink:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Multiply (1) by 4 subtract from (2):

8p + 10d = 174.50 _______(2)

-<u> 8p + 8d = 156 </u> __________(1)

2d = 18.50

=> d = $9.25

The price of one drink is $9.25

Which choice is equivalent to the quotient shown here when x is greater than or equal to 0?

Dima020 [189]

Answer: OPTION C

Step-by-step explanation:

Remember that:

$\sqrt[n]{a^n}=a$

And the Product of powers property establishes that:

$a^m*a^n=a^{(mn)}$

Rewrite the expression:

$\frac{\sqrt{18x} }{\sqrt{32} }$

Descompose 18 and 32 into their prime factors:

$18=2*3*3=2*3^2\\32=2*2*2*2*2=2^5=2^4*2$

Substitute into the expression, then:

$\frac{\sqrt{(2*3^2)x} }{\sqrt{2^4*2} }$

Finally,simplifying, you get:

$\frac{3\sqrt{(2)x} }{2^2\sqrt{2} }=\frac{3\sqrt{2x}}{4\sqrt{2}}=\frac{(3)(\sqrt{x})(\sqrt{2})}{(4)(\sqrt{2})}= \frac{3\sqrt{x}}{4}$

Find the length of the line segment shown. Round your answer to the nearest tenth.

Marina86 [1]

Answer:

$d=10$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step 1: Define endpoint coordinates

(2, 5)

(-6, -1)

Step 2: Substitute and Evaluate

$d=\sqrt{(-6-2)^2+(-1-5)^2}$

$d=\sqrt{(-8)^2+(-6)^2}$

$d=\sqrt{64+36}$

$d=\sqrt{100}$

$d=10$

A rectangle has a base length of 12 inches and an unknown height, h. The area of the rectangle is less than 60 square inches. Wh

saveliy_v [14]

Answer:

12h < 60

Step-by-step explanation:

A rectangle, with height h and base length l, has the following area.

$A = l*h$

In this question:

$l = 12, A < 60$

So

$A < 60$

$l*h < 60$

$12h < 60$

So the correct answer is:

12h < 60
