Erin runs laps each day on a track that is 4/8 miles long. This week, she ran 4 4/8 miles on the track. How many laps did she run?

Answers

Answer 1

Answer: First, we're going to convert the mixed number into a/n improper fraction.
(4 × 8 ) + 4 = 36/8

Now we're going to divide 36/8 by 4/8 since 4/8 = 1 lap.
36 / 4 = 9.

That is how we get our answer, 9 laps.

Our final answer is 9 laps.

Hope this helps!~

What is Arithmetic progression?

The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).

The arithmetic progression has wider use in mathematics for example sum of natural numbers.

As per the given,

Number of seats in one row = 9

Total number of seats = 126

Maximum number of possible rows =126/9 = 14 rows

Total number of people seated = 90

Number of rows filled = 90/9 = 10 rows

Empty rows = 14 - 10 = 4 rows.

Hence "In the meeting room, four rows will be left unoccupied".

Alright. Let us start to solve!

126 seats is the total.

9 seats for each row.

90/9 = 10

10 rows are already occupied.

126/9 = 14

there are 14 rows altogether.

Since 10 are occupied, and there are 14, we subtract.

14-10 = 4

Answer: There are 4 rows empty

Carl has three lengths of cable,5/6/ yard long,1/4 yard long, and 2/3 yard long.He needs at least 1 yard of cable.A. which two pieces together make a length at least 1 yard and closest to 1 yard?
B. If Carl uses the two short pieces,how much more cable would be need?
C. After Carl has used 1 yard of cable,how much cable will he have left?explain your answer

Answers

Answer:

A- 5/6 and 1/4

B- 1/12

C- 3/4

Step-by-step explanation:

Given : Carl has three lengths of cable,

Cable 1 - $(5)/(6)$ yard long,

Cable 2 - $(1)/(4)$ yard long,

Cable 3 - $(2)/(3)$ yard long

He needs at least 1 yard of cable.

A. Which two pieces together make a length at least 1 yard and closest to 1 yard?

We can form possible piece together

Taking 5/6 and 1/4

$(5)/(6) +(1)/(4)= (20+6)/(24)=(26)/(24)=1.08$

Taking 1/4 and 2/3

$(1)/(4) +(2)/(3)= (3+8)/(12)=(11)/(12)=0.91$

Taking 5/6 and 2/3

$(5)/(6) +(2)/(3)= (15+12)/(18)=(27)/(18)=1.5$

Length at least 1 yard and closest to 1 yard is the 5/6 yard and the 1/4 yard together.

B. If Carl uses the two short pieces,how much more cable would be need?

The two short pieces 1/4 and 2/3 makes 11/12 of a yard,

So, he would need $1-(11)/(12)= (12-11)/(12)=(1)/(12)$ yards more of cable.

C. After Carl has used 1 yard of cable,how much cable will he have left?

Altogether he has $(5)/(6) +(1)/(4)+(2)/(3)=(126)/(72)=1and(3)/(4)$ yards of cable.

If he took the 1 cable needed, he would then have 3/4 of a yard leftover.

a. the 5/6 yard and the 1/4 yard
b. the two short pieces makes 11/12 of a yard, he would need 1/12 yards more of cable.
c. altogether he has 1 and 3/4 yards of cable. If he took the 1 cable needed, he would then have 3/4 of a yard leftover.
