A plane intersects the center of a sphere
with a volume of about 9,202.8 m3. What is
the area of the cross section? Round to the
nearest tenth.

Answers

Answer 1

Answer:

530.66

Step-by-step explanation:

The computation of the area of the cross section is shown below

Given that

Volume = 9208 m^3

Now let us assume the radius be r

So volume = 4 ÷ 3 πr^3

9202.8 × 3 ÷ 4π = r^3

27,608.4 ÷ 4 × 3.14 = r^3

27,608.4 ÷ 12.56 = r^3

2,198.12 = r^3

r = 13

Now the area of the cross section is

= πr^2

= 3.14 × (13)^2

= 530.66

Find the solution set of the inequality
8x−8≤−72.

Answers

Answer:

x≤-8

Step-by-step explanation:

When solving 8x-8≤-72, first add 8 to both sides of the inequality.

This leaves you with 8x≤-64.

Divide both sides by 8: 8x/8 and -64/8

This leaves you with x≤-8 as your solution.

ROUND YOUR ANSWER TO THE NEAREST HUNDREDTHS. *

Answers

Answer:

Twenty cookies deal

Step-by-step explanation:

A dozen cookies cost 18.75. A dozen is exactly 12. If you divide 18.75 by 12 you should get the unit price which is about $1.56 for each cookie. For 25.50 you just divide it by 20 and you should get about 1.20 which makes it a better deal.

PLEASE HELP

Answers

Answer:

A) y=3x+1

Step-by-step explanation:

Use the formula y=mx+b

m is the slope and b is the y intercept

the graph starts on 1 on the y axis so you replace 1 for b

the slope goes up 3 and over one, giving the fraction 3/1 or just 3. so you replace 3 for m.

Answers

Answer:

$2.20

Step-by-step explanation:

If you do long division you get 2 dollars as total with a decimal of 20 do that's your answer.

Answer:

The cost per pound of potatoes is $2.26.

Step-by-step explanation:

You have to divide the total cost by the total pounds.

So in this case, the total cost is $18.08.

There is a total number of 8 pounds.

So you do:

$18.08 / 8 pounds

             =

$2.26/lb of potatoes

have a great day!!!

If two ratios are similar we called the ratios to be in proportion.

The length of side x is 6 cm.

What is proportion?

If two ratios are similar we called the ratios to be in proportion

We have,

Two shapes:

Consider the bigger shape width = 15 cm and length = 10 cm.

Consider the smaller shape width = 9 cm and length = x cm.

Let the ratio of bigger shape:

= Width / length

= 15/10

Let the ratio of smaller shape:

= Width / length

= 9/x

If the two figures are mathematically similar we can say that the two figures are in proportion.

We can write it as:

15/10 = 9/x

3/2 = 9/x

x = 6

Thus the length of side x is 6 cm.

Sra bought a pair of shoes that were on sale for 30 percent off. If the oringal prices was 29 what is the sale price on the shoes?

Answers

Answer:

$20.30

Step-by-step explanation:

Original price = 100% of the price

100% = $29

1% = 29 ÷ 100 = 0.29

Sale percentage = 30%

30% = 0.29 x 30 = 8.70

Since they are asking for the sale price of the shoes, it means the price of the shoes after the discount of the sale percentage.

29 - 8.70 = 20.3

Read the passage below from Marigolds and answer question Miss Lottie's house was the most ramshackle of all our ramshackle homes. The sun and rain had long since faded its rickety frame siding from white to a sullen gray. The boards themselves seemed to remain upright not from being nailed together but rather from leaning together, like a house that a child might have constructed from cards. A brisk wind might have blown it down, and the fact that it was still standing implied a kind of enchantment that was stronger than the elements. There it stood and as far as I know is standing yet a gray, rotting thing with no porch, no shutters, no steps, set on a cramped lot with no grass, not even any weeds-a monument to decay. clues to the meaning of the word ramshackle?
