You multiply 8 by 1 because if you round up it will be an estimate
8 x 1 = 8
So Kim is wrong

Answer with Step-by-step explanation:

Kim multiplied 8×0.952 and got 76.16.

As we can see 0.952 is a number near to 1

i.e. 0.952 ≈ 1

So, 8×0.952 ≈ 8×1

i.e. 8×0.952 ≈ 8

There is a huge difference between 8 and 76.16

Hence, Kim's answer is incorrect

Annabeth has $29.00 to spend at the sporting goods store. She buys a T-shirt that costs $15.32. She also wants to buy a soccer b

Gekata [30.6K]

Answer:

The most expensive she can buy is the soccerball

Step-by-step explanation:

Given

$Total =\$29.00$

$T\ Shirt = \$15.32$

$Soccer\ Ball= \$12.87$

$Baseball\ Cap = \$8.39$

$Shin\ Guards = \$14.98$

$Water\ Bottle = \$5.93$

Required

Using $\$15.32 + c = \$29.00$ , what is the most expensive she can buy?

$\$15.32 + c = \$29.00$

Subtract $15.32 from both sides

$\$15.32 - \$15.32 + c = \$29.00 - \$15.32$

$\$15.32 - \$15.32 + c = \$13.68$

$c = \$13.68$

This means that she can not afford items that cost more than $13.68

i.e. the shin guards which costs $14.98

The items she can afford and their prices are:

$Soccer\ Ball= \$12.87$

$Baseball\ Cap = \$8.39$

$Water\ Bottle = \$5.93$

The most expensive of them all is:

$Soccer\ Ball= \$12.87$

This line crosses the point (4,5)so we can make an equation to find the slope:
$4 = a \times 5 \\ 4 = 5a \\ a = \frac{4}{5}$

A middle school took all of its 6th grade students on a field trip to see a ballet. The

Advocard [28]

By working with percentages, we will see that there are 1,080 seats in the theater.

<h3>How many total seats were in the theater?</h3>

We know that the students filled 702 seats, leaving 35% vacant.

Then 702 seats represents the (100% - 35% = 65%) of the total number of seats.

So, if the total number of seats is S, we can write:

(65%/100%)*S as the 65% of S.

Then we solve:

(65%/100%)*S = 702

0.65*S = 702

S = 702/0.65 = 1,080

There are 1,080 seats in the theater.
