Tareq is 7 years old and his older sister Fatma is 10. Tareq challenges his sister to a pizza eating contest. They each make an identical extra extra large pizza. Tareq eats 2/8 of his pizza. His sister Fatma eats 3/4 of her pizza. Who ate more pizza and how do you know?

Answers

Answer:

Fatima ate more pizza

Step-by-step explanation:

Assume

The total pizza = 1

Tareq eats 2/8 of his pizza

Tareeq = 2/8 of 1

= 2/8 * 1

= 2/8

= 0.25 of his pizza

Fatma eats 3/4 of her pizza

Fatima = 3/4 of 1

= 3/4 * 1

= 3/4

= 0.75 of her pizza

The pizza is identical in size

Therefore,

Fatima ate more pizza

I got to know this by finding the decimal of fraction eaten and picking the larger decimal value as who ate more pizza

A cylindrical container of three rubber balls has a height of 27 centimeters and a diameter of 9 centimeters. Each ball in the container has a radius of 4.5
centimeters. Find the amount of space in the container that is not occupied by rubber balls. Round your answer to the nearest whole number.

Answers

Answer:

Volume of space in cylinder = 572.27 cm³ (Approx.)

Step-by-step explanation:

Given:

Height of cylinder = 27 cm

Diameter of cylinder = 9 cm

Radius of cylinder = 9 / 2 = 4.5 cm

Number of sphere ball = 3

Radius of sphere ball = 4.5 cm

Find:

Volume of space in cylinder

Computation:

Volume of space in cylinder = Volume of cylinder - Volume of 3ball

Volume of space in cylinder = πr²h - 3[(4/3)πr³]

Volume of space in cylinder = [22/7][4.5]²[27] - 3[(4/3)[22/7][4.5]³]

Volume of space in cylinder = [(3.14)(20.25)(27)] - [(4)(3.14)(91.125)]

Volume of space in cylinder = 1,716.795 - 1,144.53

Volume of space in cylinder = 572.265

Volume of space in cylinder = 572.27 cm³ (Approx.)

A certain psychological test measures empathy and emotional intelligence. The score, S, of a randomly selected senior student at a large university has a mean of 123 and a standard deviation of 29.

The box for a computer game measures 19 cm by 14 cm by 1.5 cm. What is the total amount of plastic wrapping needed to cover the entire box if an extra 66 square cm are needed to allow for overlapping at the edges?

Answers

Answer:

697 cm²

Step-by-step explanation:

The box for a computer game measures 19 cm by 14 cm by 1.5 cm.

The amount of plastic wrapping needed to cover the entire box is calculated using the formula for the Surface Area of a rectangular prism

The formula is given as:

A=2(wl +hl + hw)

W = Width = 19cm

L = Length = 14 cm

H = Height = 1.5 cm

2 × (19 × 14 + 1.5 × 14 + 1.5 × 19)

= 631 cm²

Therefore, the total amount of plastic wrapping needed to cover the entire box if an extra 66 square cm are needed to allow for overlapping at the edges is calculated as:

631 cm² + 66 cm²

= 697 cm²

5x + 2(x + 4) = 64
how do I solve for something like this and figure out what x equals?​

Answers

Answer:

There are many way to solve this problem. But I'm using one X = 5 and X = 8.

Step-by-step explanation:

5 x 10 = 50

50 + 2 = 52

52 + 12 = 64

Heads up

4 + 8 = 12

Answer:

x=8

Step-by-step explanation:

first you have to multiply 2 and x and then 2 and 4. You should get 2x + 8. then you should add comon numwrals which would be 5x and 2x to get 7x. your equation should now be 7x + 8= 64. then subtract 8 from 64 to get 56. it should now be 7x = 56. devide 56 by 7 and 7x by 7. your answer is x=8
