B) 27 inches

C) 44 inches

D) 66 inches

Answers

If an ostrich is 108 inches tall. Then the height of the kiwi will be 22 inches. Then the correct option is A.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The height of an ostrich is 20 inches more than 4 times the height of a kiwi.

Let y be the height of the ostrich and x be the height of a kiwi. Then the equation is given as,

y = 4x + 20

If an ostrich is 108 inches tall. Then the height of the kiwi will be

108 = 4x + 20

4x = 88

x = 22

If an ostrich is 108 inches tall. Then the height of the kiwi will be 22 inches. Then the correct option is A.

#SPJ2

h=height of ostrich
k=height of kiwi
h is 20 more than 4 times k
k=20+4k

k=108
108=20+4k
minus 20 from both sides
88=4k
divide both sides by 4
22=k

answer is A

To convert a measurement, Pete must move the decimal point to the left 4 places. This a shortcut for the operation. which operation is he using? Which power of 10 is involved?

Answers

The operation that Pete is using is the operation of multiplying numbers by decimal numbers and the power of 10 involved is 4

If Pete must move a decimal point to the left in 4 places, then the operation she is using is the operation of multiplying numbers by decimal numbers.

  • Since the movement is to the left in 4 places, the power of 10 involves will be a 4

For example,

  • if we are to convert 0.56 say to scientific notation to the power of 4. We will need to move the decimal point to the left 4 times to have 0.000056 * 10^4

Hence the operation that Pete is using is the operation of multiplying numbers by decimal numbers and the power of 10 involved is 4

The moving of decimal to the left is a shortcut to the operation of multiplying number by decimal numbers. So the power of 10 that is involved in converting the measurements of pete is -4, so he needs to multiply the measurement by 10^-4 to convert it.

A ball is thrown straight up from the top of a 40 feet tall building with an initial speed of 24 feet per second. The height of the ball as a function of time can be modeled by what function h(t) = _________________ 1. after how many seconds the ball hit the ground. 2.What is the maximum height of the ball? 3.How long did it take for the ball to reach its maximum height?

Answers

Answer:

1)The ball hits the ground after 3 seconds.

2)The maximum height of the ball is 49 feet

3)It takes 1.25 seconds to reach its maximum height

Step-by-step explanation:

Height of building = 40 feet

We are given that A ball is thrown straight up from the top of building with an initial speed of 24 feet per second.

So, The height of the ball as a function of time can be modeled by: h(t)=-16t^2+40t+24

1)After how many seconds the ball hit the ground.

Substitute h(t)=0

So,-16t^2+40t+24=0\n-2t^2+5t+3=0\n2t^2-5t-3=0\n2t^2-6t+t-3=0\n2t(t-3)+1(t-3)=0\n(2t+1)(t-3)=0\nt=(-1)/(2) , 3

Since time cannot be negative

So,the ball hits the ground after 3 seconds.

2)What is the maximum height of the ball?

It takes maximum height at vertex

Formula : t = (-b)/(2a)

t=(-40)/(2(-16))=1.25 seconds

Substitute the value of t in function

h(1.25)=-16(1.25)^2+40(1.25)+24\nh(1.25)=49 feet

So,the maximum height of the ball is 49 feet

3).How long did it take for the ball to reach its maximum height?

It takes 1.25 seconds to reach its maximum height
