The surface area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for π. Round your answer to the nearest hundredth. A. 696.99 cm3 B. 133.97 cm3 C. 267.95 cm3 D. 334.94 cm3

Answers

Answer:

267.95cm^3

Step-by-step explanation:

S= 4πr^2

Surface area is 200.96

π= 3.142

200.96= 4×3.142×r^2

200.96= 12.57r^2

r^2= 200.96/12.57

= 15.99

= √15.99

r = 3.9

Volume= 4/3πr^3

= 4/3× 3.142×3.9^3

= 267.95 cm^3

The process of writing a number as the product of prime numbers is prime factorization. Prime numbers are the numbers that have only two factors, 1 and the number itself.

The numbers between 40 and 45 are 41, 42, 43 and 44.

The factors of the numbers are as follows

41 = 1×41

42 = 1×2×3×7

43 = 1×43

44 = 1×2×2×11

Therefore, the number which has prime factors of 2 and 7 and in between 40 and 45 is 42.

Show me how to find x using the correct equation shown here (geometry)

Answers

Answer:

x = 13

Step-by-step explanation:

The 2 angles same- side interior angles and sum to 180°

Then the equation to use to find x is

12x - 29 + 4x + 1 = 180

16x - 28 = 180 ( add 28 to both sides )

16x = 208 ( divide both sides by 16 )

x = 13

Answer:

13

Step-by-step explanation:

Angles ( 12x - 29 ) and ( 4x + 1 ) are co - interior angles.

Sum of co - interior angles are supplementary.

12x - 29 + 4x + 1 = 180

12x + 4x - 29 + 1 = 180

16x - 28 = 180

16x = 180 + 28

16x = 208

x = 208 / 16

x = 13

Consider circle O, where mBD =70° and mCA = 170°

m∠BPD: ____°.

mBC + mAD = ____°.

Answers

Answer:

m∠BPD: 120°

mBC + mAD =120°

Step-by-step explanation:

m∠BPD: 120°mBC + mAD =120°What is angle?

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

Given:

mBD =70°

mCA = 170°

So,

m∠BPD= 1/2( (m∠BD + m∠CA))

=1/2(170+70)

=1/2*240

=120

and,

mBC + mAD = 360 - ( 70 + 170 )

                    = 360 - 240

mBC + mAD = 120°

Rocco has a weekly reading schedule, reading for 4.5 hours per day on some days and 3.5 hours per day on the other days. He reads a total of 25.5 hours in a seven-day week. On how many days does he read for 4.5 hours?

Answers

Answer:

x = days he reads for 4.5 hours = 1 day

y = days he reads for 3.5 hours = 6 days

Step-by-step explanation:

Let

x = days he reads for 4.5 hours

y = days he reads for 3.5 hours

x + y = 7 (1)

4.5x + 3.5y = 25.5 (2)

From (1)

x = 7 - y

Substitute x = 7 - y into (2)

4.5x + 3.5y = 25.5 (2)

4.5(7 - y) + 3.5y = 25.5

31.5 - 4.5y + 3.5y = 25.5

- 4.5y + 3.5y = 25.5 - 31.5

-y = -6

y = 6

Substitute y = 6 into (1)

x + y = 7 (1)

x + 6 = 7

x = 7 - 6

x = 1

x = days he reads for 4.5 hours = 1 day

y = days he reads for 3.5 hours = 6 days

10n+0.3=0.1n+0.3 Solve for N

Answers

Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

10n+0.3=0.1n+0.3

Step 1: Subtract 0.1n from both sides.

10n+0.3−0.1n=0.1n+0.3−0.1n

9.9n+0.3=0.3

Step 2: Subtract 0.3 from both sides.

9.9n+0.3−0.3=0.3−0.3

9.9n=0

Step 3: Divide both sides by 9.9.

9.9n/ 9.9 = 0/ 9.9

n=0

Answer:

n=0

Answer:

0

Step-by-step explanation:

10n - .1n = 9.9n

9.9n + .3 = .3

subtract .3 from the other one and get 0

9.9n = 0 then divide and it comes out to 0
