Step-by-step explanation:

There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.

The number is students not trying out for football last Thursday is calculated as:

376 students - 47 students

= 329 students

The percent of 8th graders that did not try out for football is calculated as:

329 students/376 students × 100

= 329/376 × 100

= 87.5 %

A store buys a television for $120.

The store then sells the television for $300.

The makeup is the amount they increased the cost price by to get to the selling price.

Answer: 120, 240, 480

Step-by-step explanation:

It would appear that the numbers are increasing in multiples of 2.

15 * 2 = 30

30 * 2 = 60

The next 3 terms will therefore be:

60 * 2 = 120

120 * 2 = 240

240 * 2 = 480

Jada is moving faster

Jade goes 10 miles in one hour

Han goes 2.5 miles in one hour

Step-by-step explanation:

Jada is 2miles/12 minutes=2(5) miles in 12(5) minutes

Jade goes 10 miles in 60 minutes (or one hour)

Han is 1 mile/24 minutes=1(2.5) miles in 24(2.5) minutes

Han goes 2.5 miles in 60 minutes (or one hour)

Jada is moving faster

Answer:

it's 6

Step-by-step explanation:

2*3 is 6 and I*I is i^2 which equals to 1 so overall 6

Answer:

-6

Step-by-step explanation:

2i* 3i

Multiply the numbers 2*3 = 6

Multiply the imaginary number i*i = i^2

We know that i^2 = -1

6* i^2 = 6*-1 = -6

The time required when 3 electricians are working is 9 hours and 20 minutes.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The time required to complete the job varies inversely with the number of people working.

This means that if the number of people working decreases, the time required to complete the job will increase.

We can use the formula for inverse variation to solve the problem:

t = k/n

where t is the time required to complete the job, n is the number of people working, and k is a constant of proportionality.

We can find k by plugging in the given values:

4 = k/7

k = 28

Now we can use the formula to find the time required when 3 electricians are working:

t = 28/3

t ≈ 9.33 hours

Converting this to hours and minutes, we get:

t ≈ 9 hours and 20 minutes

Thus,

The time required when 3 electricians are working is 9 hours and 20 minutes.

Answer 9.5

you do the pyragtaham theory thing its A(squared) + B (squared) = C squared

you put the 3 at the A and you put the 10 at the C you sqaure them all up and then subtrct 9 from 100 and you get 91 and then you square root 91 and you get 9.5

The distance from the top of the ladder to the ground is 9.54 ft.

"It is a triangle whose one of the angle is 90°"

"The longest side of the right triangle is called as hypotenuse."

"For a right triangle,

c² = a ² + b²,

where c = hypotenuse and a, b are other two sides of right triangle."

For given example,

Gwendolyn placed a ladder against the side of her house.

This means, it makes right triangle with ladder hypotenuse and base of the triangle is the distance between base of the ladder and the base of the house.

Let 'a' be the hypotenuse of triangle, 'b' be the base and  'd' be the distance from the top of the ladder to the ground

⇒ a = 3 ft. and b = 10 ft.

Using Pythagoras theorem,

⇒ b² = a² + d²

⇒ 10² = 3² + d²

⇒ 100 = 9 + d²

⇒ d² = 91

⇒ d = 9.54 ft.

Therefore, the distance from the top of the ladder to the ground is 9.54 ft.
