B: (0.5)(–0.5)(3.2)(7.9)(–2.4)

C: (0.5)(–0.5)(3.2)(–7.9)(–2.4)

D: (0.5)(–0.5)(3.2)(–7.9)(–2.4)(0)

Answers

Answer 1
Answer:

Answer:

C

Step-by-step explanation:

Rules of multiplying numbers with positive and negative signs are the following:

  • (-)(-) = +
  • (+)(+) = +
  • (-)(+) = -
  • (+)(-) = -

This means that there should be an odd number of negative numbers in a product to get a negative number.

A will be positive.

B will be positive.

C will be negative.

D will be neither since 0 is its product

What is the volume of a hemisphere with a radius of 3 cm, rounded to the nearest tenth of a cubic centimeter?

Answers

The Volume of sphere whose radius is 3 cm = 113 cm^(3) (rounded to the nearest tenth)

Volume= 113 cm^(3)

What is Volume of sphere?

The volume of a sphere = 4/3 r³, where r is the radius of the sphere.

Volume of sphere = (4)/(3) * \pi* r^(3)

                               = (4)/(3) * 3.14* (3)^(3)

                               = 4 x 3.14 x 9

                               =113.04 cm^(3)

                               ≈ 113 cm^(3) (rounded to the nearest tenth)

Final answer:

The volume of a hemisphere with a radius of 3 cm is approximately 56.6 cm³ when rounded to the nearest tenth of a cubic centimeter. This is calculated by halving the volume of a sphere with the same radius.

Explanation:

Calculating the Volume of a Hemisphere

The question asks for the volume of a hemisphere with a radius of 3 cm. The formula for the volume of a sphere is V = (4/3)πr³, and since a hemisphere is half of a sphere, the formula adapts to V = (1/2)(4/3)πr³. Using a radius (r) of 3 cm, we get V = (1/2)(4/3)π(3 cm)³.

Let's calculate the volume step by step:

  1. First, calculate the volume of the full sphere using the radius of 3 cm: V = (4/3)π(3³) cm³
  2. Compute the result: V = (4/3)(π)(27) cm³ = (36π) cm³
  3. Since we want the volume of the hemisphere, we divide this number by 2: V = (36π/2) cm³ = (18π) cm³
  4. Finally, we approximate π to 3.142 and round to the nearest tenth: V ≈ 18(3.142) cm³ ≈ 56.6 cm³

Therefore, the approximate volume of the hemisphere is 56.6 cm³, when rounded to the nearest tenth of a cubic centimeter.

Kevin has $1,427 in a savings account his brother Haley has saved in the mouth with a 4 that is 1/10 the value of the 4 in Kevin's savings account. how much could Harley have In his savings account?

Answers

Answer:

$40.00

Step-by-step explanation:

Kevin has in a savings account = $1,427

His brother Haley has saved in the month with a 4 that is 1/10 the value of the 4.

The value of the 4 in 1,427 is at hundredth place = 4 × 100

and 1/10 of 400 = 40

Therefore, Haley have $40.00 in his savings account.

1/10 of 400 is 40
$1,427-40= $1387
so Haley's account has 1387 dollars or less

Sydney says that 4/8 is closer to 0 than to 1. Is she correct?

Answers

No.  When Sydney says that 4/8 is closer to 0 than to 1, she is incorrect.

4/8 is the number that's exactly in the perfect middle between 0 and 1.
It's distance from 0 and its distance from 1 are precisely the same.
when you simplify 4/8 you get 1/2 so it`s the same distance from 0 and 1

ms.Alonzo ordered 4,000 markers for her store. only one tenth of them arrived . how many markers did she receive

Answers


Ms. Alonzo received 400 markers because one tenth of 4000 is 400. Hope this helped! 

400 because another way to find one tenth of something is to divide by 10 so you would simply do 4,000 divided by 10 to get 400. HOPE I HELPED!!!
