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

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°

Which of the following statements MUST be true?
A) An odd number of factors were negative.
B) None of the factors were negative.
C) An even number of factors were negative.
D) All of the factors were negative.
Answer:
c
Step-by-step explanation:
make y the subject please help
Step-by-step explanation:
Square both sides and you will get
3xy/(x + y) = 4
Multiplying both by (x + y), we get
3xy = 4(x + y) = 4x + 4y
Put all the terms containing y to the left side:
3xy - 4y = 4x
y(3x - 4) = 4x
or y = 4x/(3x - 4)
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

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
A number is between 40 and 45. It has prime factors of 2 and 7. What is the number?
Answer:
42
Step-by-step explanation:
42 is divisible by both 7 and 2
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.
