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

Answer 1
I think the answer is C 904.32 in.3
Answer 2

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

Which value of x makes the equation true?
−4=1.5x+5

Answers

Answer:

For x = -6

Step-by-step explanation:

1.5x + 5 = -4

1.5x = -4 - 5

1.5x = -9

x = -6

Checking: 1.5 * -6 + 5 = -4

x = -6


1. You subtract 5 to both sides
2. divide 1.5 to the other number

Step-by-step explanation:

so, the answer is -4.

Answer:

-4°C

Key:

( | | ) = these in between numbers is the absolute value. EXAMPLE: |-8| = 8

Step-by-step explanation:

If it was -9°C and it INCREASED by 5°C, you need to ADD.

-9°C + 5°C

*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and  make it either positive or negative, depending on which absolute value is the greatest (|9|).*

-9°C + 5°C OR |9| - |5|

|9°C| - |5°C| = |4°C| = -4°C

(because the greatest absolute value, |9|, is negative, the answer is too.)

Answers

0.5 < x < 16.5 given: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
Sum of any two sides > third side. (i)
Difference between the sides < third side. (ii)
If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.

While sitting on a park bench, Tanisha counts that 16 out of 20 people who walk by her have a pet with them.

Part A. What is the probability that a person who walks by Tanisha has a pet?

Part B. What is the probability that a person who walks by her does not have a pet?

Answers

Answer:

the answer would be-

Step-by-step explanation:

The probability that a person who walks by Tanisha has a pet- 0.8

The probability that a person who walks by Tanisha does not have a pet- 0.2

What is probability?

Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability of Event = Favorable Outcomes/Total Outcomes = X/n

Part A. The probability that a person who walks by Tanisha has a pet can be calculated by dividing the number of people who have a pet by the total number of people who walk by her. In this case, 16 out of 20 people have a pet, so the probability is:

P(having a pet) = 16/20 = 4/5 = 0.8

So, the probability that a person who walks by Tanisha has a pet is 0.8 or 80%.

Part B. The probability that a person who walks by Tanisha does not have a pet can be calculated by subtracting the probability of having a pet from 1. That is:

P(not having a pet) = 1 - P(having a pet)

P(not having a pet) = 1 - 0.8

P(not having a pet) = 0.2

So, the probability that a person who walks by Tanisha does not have a pet is 0.2 or 20%.

Answer:

For question 2, it is C) 3a.

For question 3, it is B) 3.

Step-by-step explanation:

For question 2, we are given that Mary's age is a and her mother's age is 3 times as old as Mary. The key word is "times" so this means that the expression can be written as 3a or 3 * a.

For question 3, the question asks for the greatest number that divides evenly into both 42 and 81. Using simple math, C and D automatically elliminates itself because one of the numbers divided gives a whole and the other gives a decimal. All is left is A and B. Obviously, a number divided by one will by itself so it stays even either way and the two numbers divided by 3 will give us two whole numbers and 3 is the greatest possible number so that concludes that it is B.

"Find the measure of each angle in the following diagram"

Answers

Answer:

Each angle is 60°

Step-by-step explanation:

The 2 angles are equal to each other because they're alternate exterior angles:

10x - 20 = 7x + 4

10x - 7x = 4 + 20

3x = 24

x = 8

10x - 20

10(8) - 20

80 - 20

60

Since these angles are exterior angles, their angle measures are equal so they both are 60°

60 degrees is the measurement of each angle :)
