Answer 1

Answer:

10yds

Step-by-step explanation:

The perimeter is 2 * length + 2 * width.

If the perimeter is 90ft, which has to be converted to yards: 90/3=30yds

(Remember 3 feet in a yard)

and the width is 5yds

So:

2*length + 2* 5 = 30

2 * length = 20

length = 10

Answer 2

10 yss is the length of the pool

The two dot plots below show the heights of some sixth graders and some seventh graders:

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot for the first mark, there are 3 dots above the second mark, 2 dots above the third mark.

The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.6. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.) (5 points)

Math:

Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?

Answers

Answer:

42.66%

Step-by-step explanation:

subtract the amount of money from after and before: 1,635.30 - 1,422 = 213.3

divide the amount of money gained by the years: 213.3/5 = 42.66

The person above is correct because if you take the original amount Kim had and subtract that from the amount currently there you get 213.30 and you take that and divide that by 5 because of the 5 years you get
42.66%

of the peach pie was eaten

What is the total amount of Luis' pies that were left over?

Answers

Answer:

2 1/4 pies

Step-by-step explanation:

Find out how much pie was leftover from each pie:

Apple pie: 3/4, 4 - 3 = 1, 1/4

Blackberry: 1/2, 2 - 1 = 1, 1/2

Blueberry: 1/8, 8 - 1 = 7, 7/8

Cherry: 5/8, 8 - 5 = 3, 3/8

Peach: 3/4, 4 - 3 = 1, 1/4

There are 1/4, 1/2, 7/8, 3/8, and 1/4 pies left. The LCD if these numbers is 8, since 2*4 = 8, 4*2 = 8, and 8*1 = 8

1/4 = 2/8

1/2 = 4/8

7/8 = 7/8

3/8 = 3/8

1/4 = 2/8

2 + 4 + 7 + 3 + 2 = 18, so 18/8 pies, or 2 2/8, or 2 1/4

The surface area of a lantern shaped like a sphere is 452.16 square inches. What is the approximate volume of the lantern? Use 3.14 for π. Round your answer to the nearest hundredth.
A.150.72 in.3
B.452.16 in.3
C904.32 in.3
D.5,425.92 in.3

Answers

I think the answer is C 904.32 in.3

The approximate volume of the lantern is, V = 904.32 in³

How can the surface area of this sphere can be expressed ?

The concept here is using the surface area formula which is

A = Area = (4 π r² )

V= Volume =( 4/3 π r³)

Then , We get;

A / V = 3 / r

Also, r = √A / 4π

Then we can substitute the values as

π = 3.14

r = √452.16 / 4×3.14

r = √36

r = 6

Hence, We get;

V = 4/3 πr³

V = 4/3 × 3.14 × 6³

V = 904.32 in³

Answer:

Circumference formula:

C = πd

π is the constant and π = 3.14

A) C = 3.14*3 cm = 9.42 cmB) C = 3.14*10 = 31.40 cmC) d = 24/3.14 = 7.64 cmD) d = 18/3.14 = 5.73 cmE.) C = 3.14*1 = 3.14 cm

Answer:

Círclє Díαmєtєr Círcumfєrєncє

( A ). 3 cm 9.42 cm

( B ). 10 cm 31.40 cm

( C ). 7.64 cm 24 cm

( D ). 5.73 cm 18 cm

( E ). 1 cm 3.14 cm.

Step-by-step explanation:

Formula used

◈ Circumference of circle = π × diameter

◈ Diameter of circle = Circumference of circle / π

Solution

usíng vαluє σf π = 3.14

( A ) Díαmєtєr = 3 cm

Círcumfєrєncє = 3.14 × 3 = 9.42 cm.

( B ) Díαmєtєr = 10 cm

Círcumfєrєncє = 3.14 × 10 cm = 31.40 cm.

( C ) Círcumfєrєncє = 24 cm

Díαmєtєr = 24 / 3.14 cm = 7.64 cm.

( D ) Círcumfєrєncє = 18 cm

Díαmєtєr = 18 /3.14 = 5.73 cm.

( E ) Díαmєtєr = 1 cm

Círcumfєrєncє = 3.14 × 1 cm = 3.14 cm.
