Which answer choice correctly identifies the missing information in the problem?Joey and Kirk are in the 6th grade. Kirk is 5 feet 4 inches tall. Joey is 4 feet 8 inches tall. How much taller is Kirk than Joey?A.The missing information is there is 12 inches in 1 foot.B.The missing information is how old Joey and Kirk are.C.The missing information is Joey and Kirk's last name.D.The missing information is who is taller, Joey or Kirk.

Answers

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:AStep-by-step explanation:1 - Work through the problem

Kirk:

5' 4" tall

Joey

4' 8" tall

1.1 - Convert to inches

Kirk: 5' = (12*5) inches (Every foot is 12 inches) = 60 inches + 4 = 64 inches

Joey: 4' = (12*4) inches = 48 inches + 8 = 56 inches

1.2 - Find the difference

64 - 56 = 8 inches (Since its not divisible by 12 we leave it as is.)

Because I was able to solve this without trouble there is no missing info. Letter A

Alright, If x+y=7 then y=7-x. If we plug that in then 3x+7-x=45 leads that 2x+7=45 so 2x=38, therefore, x=19 now if x+y=7 and x=29 we know that y=-22. Hope this helped! Try finding the answer now!

A man drove his car a distance of 315 miles in 5 hours. If continuing at this rate is possible, he will travel ____ miles in 9 hours. (5 points)

Answers

He will travel 567. You first divide 315 by 5 and then that’s your rate. Then you multiply your rate by 9 to get 567 as your answer

Answer:

567

Step-by-step explanation:

Well, he traveled 63 miles every hour

So,

315+63=378

378+63=441

441+63=504

504+63=567

So, if he travels 63 miles an hour you can plus 63 to itself 4 times or you can times 63 to 4 then plus it to 315 then get your answer

∠A and ∠B are supplementary angles. If m ∠A =(2x +10)° and m ∠B= (3x +15)°, then find the measure of ∠B.

Answers

Answer:

∠B = 108°

Step-by-step explanation:

Since ∠A and ∠B are supplementary angles , it means that the sum of their angles add up to 180°

To find ∠B first find x

To find x add ∠A and ∠B and equate them to 180 to find x

We have

m ∠A + m ∠B = 180

2x +10 + 3x +15 = 180

5x + 25 = 180

5x = 180 - 25

5x = 155

Divide both sides by 5

x = 31°

From the question

m ∠B= (3x +15)°

So we have

∠B = 3(31) + 15 = 93 + 15

We have the final answer as

∠B = 108°

Hope this helps you
