A student is 1.75m tall and is trying out for the football team. He kicks the football straight up
in the air from his outstretched arms at a height of 1 m. If the ball hits him on the head on the
way back down 3 seconds later, what was the football's initial velocity?

Answers

Answer 1

Answer:  see below

Step-by-step explanation: Initial velocity = terminal velocity. At the top of travel, the velocity is 0 as the ball is motionless. Then it travels 3 seconds (due to gravity). Grav is 9.8m/sec squared. So 1st second = 9.8m. 2nd second is 2x9.8m. 3rd second is 3x9.8m = 29.4 m/sec.

Find the perimeter of the following shape

Answers

Answer:

perimeter = 2√10 + 2√5 ≈ 10.797

Step-by-step explanation:

Perimeter = DA + AB + BC + CD

DA = CB

D(4 , 4)

A(7, 5)

DA = √(7-4)² + (5-4)²

DA = √(3)² + (1)²

DA = √9+1 = √10

AB = CD

D(4, 4)

C(3, 2)

CD = √(4-3)² + (4-2)²

CD = √(1)² + (2)²

CD = √1 + 4 = √5

Perimeter = √10 +√5+√10+√5

                = 2√10 + 2√5 ≈ 10.797

Which expressions show the volume and the surface area of this cube-shaped packing box?

A cube with a dimension of 1 and five-eighths feet.

Answers

Answer and Step-by-step explanation:

The bottom right answer choice is the answer.

To find the volume, you do (length × width × height)

And to get the surface area, you do [tex]6(x)^{3}[/tex]

We just have to plug 1 [tex]\frac{5}{8}[/tex]

Where did they get [tex]\frac{13}{8}[/tex]?

They made the mixed fraction into a fraction by multiply 8 by 1, then adding that product to 5.

Which leads us to the answer choice being the bottom right.

#teamtrees #WAP (Water And Plant)

Answer:

D. V = (13/8)³ ft³, SA = 6(13/8)² ft²

Step-by-step explanation:

Volume of the cube:

V = a³

Surface area of the cube:

SA = 6a²

Given cube has side of 1 5/8 feet = 13/8 feet

Substitute the value of a:

V = (13/8)³ ft³SA = 6(13/8)² ft²

Correct option is D

Answers

Answer:

We need to solve this system of equations by substitution:

-6x-2y =20

3y=x

Yu can do it with the letter you decide

You can get the x from the second equation and replace in the first:

3y = x

-6x - 2y = 20 -> -6(3y) - 2y = 20 --> -18y - 2y = 20 --> y=-1

Then we can replace in the second one:

3*(-1) = x ---> -3 = x

So the answer is x = -3, y = -1

x=-3 and y=-1

Carnival M charges an entrance fee of and per ticket for the rides. Carnival P charges an entrance fee of and per ticket for the rides. How many tickets must be purchased in order for the total cost at Carnival M and Carnival P to be the same?

Answers

Answer:

25 tickets

Step-by-step explanation:

Carnival M charges an entrance fee of $5.00 and $0.65 per ticket for the rides. Carnival P charges an entrance fee of $10.00 and $0.45 per ticket for the rides. How many tickets must be purchased in order for the total cost at Carnival M and Carnival P to be the same?

Let

x = number of tickets

Carnival M = 5 + 0.65x

Carnival P = 10 + 0.45x

Equate both cost

5 + 0.65x = 10 + 0.45x

5 - 10 = 0.45x - 0.65x

-5 = - 0.20x

x = -5 / -0.20

x = 25 tickets

25 tickets tickets must be purchased in order for the total cost at Carnival M and Carnival P to be the same

An international company has 23,200 employees in one country. If this represents 26.7% of the company's employees, how many employees does it have in total?
Round your answer to the nearest whole number.

Answers

Answer:

Total number of employees = 86,891 employees

Step-by-step explanation:

Let

x = total number of employees

26.7% of x = 23,200

26.7/100 * x = 23,200

0.267 * x = 23,200

0.267x = 23,200

x = 23,200/0.267

x = 86,891.385767790

approximately 86,891 employees

Total number of employees = 86,891 employees

A hula hoop measures 14 inches from the center to the outside. What is the distance around the hula hoop?


A. 21.98 in

B. 175.84 in

C. 43.96 in

D. 87.92 in

Answers

Answer: D. 87.92 in

Step-by-step explanation:

The hula hoop is a circular shape so assume that this is a circle.

The 14 inches that it measure from the center to the outside is therefore the radius.

The distance around the hula hoop being looked for is the circumference.

Circumference of a circle = 2 × π × radius

= 2 * 22/7 * 14

= 88 inches

Closest answer in options is D. 87.92 inches.
