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
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

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

Answer:
A) <SQT = 36 degrees
B) <QRW = 36 degrees
C)<PRV = 72 degrees
Step-by-step explanation:
A) <SQT = 36 degrees (< SQT and < PQR are vertically opposite angles, and vertically opposite angles are equal)
B) <QRW = 36 degrees ( <QRW and < SQT are corresponding angles since they lie on the same side of the transversal across the parallel lines. Corresponding angles are equal)
C)<PRV = 72 degrees( <PRV is the exterior base angle to < PQR and exterior base angles, are always twice their interior correxpondents)

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?
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
What is y=(3x-9)(x+2) in standard form?

The number which has prime factors of 2 and 7 and in between 40 and 45 is 42.
Given that, a number is between 40 and 45. It has prime factors of 2 and 7.
What are prime factors?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.

Step-by-step explanation:
The range of a data set is the numbers covered by the data. This means that the range is the difference between the minimum and maximum. The minimum is the smallest point, 2, and the maximum is the largest point, 8. Therefore, since 8-2=6, 6 must be the range.

Consider circle O, where mBD =70° and mCA = 170°
m∠BPD: ____°.
mBC + mAD = ____°.
Answer:
m∠BPD: 120°
mBC + mAD =120°
Step-by-step explanation:
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°
