In the equation below a is a number between 0 and 1 8 x a = b which statement about the value of b is always true
Kamila [148]

Answer:

See Explanation

Step-by-step explanation:

Given

0 \le a \le 1

8*a =b

Required

Determine the true statement about b

The question is incomplete as options are not given. However, a general explanation is as follows:

Rewrite 8*a =b

b = 8 * a

When a = 0

b = 8 * 0 = 0

When a = 1

b = 8 * 1 = 8

This means that:

For 0 \le a \le 1

Then 0 \le b \le 8

<em>This means that: b is a number between 0 and 8</em>

A store has apples on sale for $20.00 for 8 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $80.0
torisob [31]

Answer:

In $80.00 , we get 102 apples.

Step-by-step explanation:

As given, 8 pound apples costs = $20.00

so,

If we double the cost given , then we get double the times of apple given

⇒ we get 16 pound apple for = $40.00

Again, double the cost , gets double the apple

⇒ we get 32 pound apple for = $80.00

As,

1 pound= 16 ounces

⇒32 pound apple = 32×16 = 512 ounces

Now,

given that

1 apple = 5 ounces

⇒5 ounce = 1 apple

⇒1 ounce = \frac{1}{5} apple

⇒512 ounces = \frac{1}{5} ×512 = 102.4 ≈ 102 apples

∴ we get

In $80.00 , we get 102 apples.
