375 fish are swimming in a school. First, 47 fish swim away. Then 116 more fish join the school. How many fish are in the school now
Answer:
The answer is 444.
Step-by-step explanation:
First, you do 375 - 47 because 47 swam away, decreasing the amount of fish that are swimming in a school. Then, 116 fish come back to swim so you add 116 to get 444.
There are 444 fish in the school now.
What is Unitary Method?The unitary method's formula is to identify the value of a single unit, then multiply that value by the number of units to obtain the required value.
The unitary approach is used when we have several goods with varying values in our possession. To get the value of one unit, we simply divide the total value by the number of units.
We have,
375 fish are swimming in a school.
First, 47 fish swim away.
Then 116 more fish join the school.
So, the number of fish in the school now
= 375 - 47 + 116
= 444 fish
Thus, there are 444 fish in school now.

A tennis ball has a radius of about 1.4 inches What is the volume of the tennis ball to the nearest half inch.? Use 3.14 as an approximation for
Answer:
Volume of tennis ball = 11.49 inch³
Step-by-step explanation:
Given:
Radius of tennis ball = 1.4 inches
Value of π = 3.14
Find:
Volume of tennis ball
Computation:
Volume of sphere = [4/3][π][r]³
Volume of tennis ball = [4/3][π][Radius of tennis ball]³
Volume of tennis ball = [4/3][3.14][1.4]³
Volume of tennis ball = [1.333][3.14][1.4]³
Volume of tennis ball = [1.333][3.14][2.744]
Volume of tennis ball = [4.1856][2.744]
Volume of tennis ball = 11.4852
Volume of tennis ball = 11.49 inch³
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?
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

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?
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

Write an equation in slope-intercept form of the line that passes through the given point and is
parallel to the graph of the given equation.
(-1,6); y = 9x - 5
Answer:
y = 9x - 15
Step-by-step explanation:
The given y = 9x - 5 is already in slope-intercept form. Any line parallel to this one has an equation that looks exactly the same except for the constant term. Call the new constant term 'C.'
Start with y = 9x - 5 and substitute the coordinates of the given point (-1, 6):
6 = 9(-1) + C, or
6 + 9 = C, or
C = 15
Then the equation of the line that passes through (-1, 6) and is parallel to y = 9x - 5 is
y = 9x - 15

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 score, F, of a randomly selected first-year student at a large university has a mean of 104 and a standard deviation of 34.
Suppose we randomly select one senior student and one first-year student. We can consider S and F to be independent random variables.
Calculate the standard deviation of the difference D = S – F.

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
