Harold walks 3/4 mile in each 5/6 hour. Calculate Harold's unit rate. Explain how you found your answer.

Answers

Answer 1
Answer: To solve this problem, you must apply the proccedure shown below:

 1. The problem gives the following information: Harold walks 3/4 miles in each 5/6 hours. Therefore, you have to divide  3/4 miles by 5/6 hours, as below:

 unit rate=(3/4)(5/6)
 unit rate=(3x6)(4x5)
 unit rate=18/20 

 3. When you simplify, you obtain:

 unit rate=9/10

 4. Therefore, as you can see, the answer is: Harold's unit rate is 9/10.

Sabrina is using an online calculator to calculate the outputs f(n) for different inputs n. The ordered pairs below show Sabrina's inputs and the corresponding outputs displayed by the calculator: (1,6), (2,11), (3,16), (4,21)

Which of the following functions best represents the rule that the calculator used to display the outputs?

A) f(n)= 5n-1

B) f(n)= 5n+1

C) f(n)= 4n+3

D) f(n)= 4n-3

Answers

Plug in the point (1,6) into each answer choice.

A) f(n) = 5n - 1
f(1) = 5(1) - 1 = 5 - 1 = 4
(1,4) ≠ (1,6)

Answer choice A is incorrect.

B) f(n) = 5n + 1
f(1) = 5(1) + 1 = 5 + 1 = 6
(1,6) = (1,6)

Answer choice B is correct.

C) f(n) = 4n + 3
f(1) = 4(1) + 3 = 4 + 3 = 7
(1,7) ≠ (1,6)

Answer choice C is incorrect.

D) f(n) = 4n - 3
f(1) = 4(1) - 3 = 4 - 3 = 1
(1,1) ≠ (1,6)

Answer choice D is incorrect.


Your answer is B) f(n) = 5n + 1

Answer:

B. f(n)= 5n+1

A triangle has sides with lengths of 5x-7, 3x-4, and 2x-6. What is the perimeter of the triangle?

Answers

(5x-7)+(3x-4)+(2x-6)

=5x-7+3x-4+2x-6

=[5x+3x+2x]+[(-7)+(-4)+(-6)]

=10x-17

⇒The perimeter of the triangle: 10x-17.

We know that the area of a parallelogram is the base * the height of it, so if we divide both sides by the height, then area/height=base. Therefore, we must divide the area by the height. To divide using polynomials, we first set it up similar to a regular long division problem:


        ______________________

2x+3 | 2x²+13x+15

Next, we take the first component of the numerator (2x² in this case) and divide it by the first component of the denominator (2x) to get x. That will form the start of our answer, and at the bottom, we will subtract our numerator by the denominator (2x+3) multiplied by the start of our answer (x). Therefore, we have


          _x_____________________

2x+3 | 2x²+13x+15

        -(2x²+3x)

        _______________

                10x+15


We then repeat the process until we finish, and whatever's left at the top is our answer. If there's something left, that's our remainder.


_x+5_____________________

2x+3 | 2x²+13x+15

        -(2x²+3x)

        _______________

                10x+15

             - (10x+15)

     _________________

0


Therefore, our base has a length of x+5.

Which steps could be used to solve this story problem? At the art store paint costs $5, brushes cost $3, and packs of pastel crayons cost $13. Kari bought 3 pots of paint, 4 brushes, and 3 packs of pastel crayons.

How much money did Kari spend?

A.
Divide $13 ÷ 3. Then add $5 and 4. Then add the quotient and the sum together and subtract 3.

B.
Add $5 and 3. Then add $3 and 4. Then add $13 and 3. Then add the 3 sums together.

C.
Multiply $5 × 3. Then multiply $3 by 4. Then multiply $13 by 3. Then add the products together.

D.
Subtract 3 from $13. Then subtract $3 from 4. Add the two differences together and multiply by $5.

Answers

C.
Multiply $5 × 3. Then multiply $3 by 4. Then multiply $13 by 3. Then add the products together

Maria bought seven boxes. A week later half of her boxes were destroyed in a fire. There are only 22 boxes left. With how many did she start?

Answers

The equation is (x+7)/2=22

X is what we need to find out. (I’m not sure if you are in algebra yet so I’m sorry if you’re not)

First we should give both sides the same denominator (22=22/1)

(X+7)/2=22/1 now we can change 22/1 to 44/2
(X+7)/2=44/2

Now since we are trying to find x, we can remove the denominator to solve for x and make it easier.

x+7=44 subtract 7 from both sides
x=37

***so your answer is 37***
