Charlie runs 2 laps in 8 minutes. How many minutes will 9 laps take him?

Mathematics
1 answer:
Fofino [41]3 years ago
8 0

Answer:

36 minutes

Step-by-step explanation:

We can write a ratio

2 laps           9 laps

-------------   = --------------

8 minutes     x minutes

Using cross products

2x = 8*9

2x = 72

Divide by 2

2x/2 = 72/2

x = 36 minutes

Horizontal and parallel lines e and f are cut by transversal b. At the intersection of lines b and e, the uppercase right angle
spayn [35]

Answer:

130

Step-by-step explanation:

From the FIQURE of the question, we can see that line "e" is parallel to line "f" then we can say (2x + 18)=( 4x - 14)

Then we can collect like terms

2x-4x= -14-18

-2x=-32

The negatives cancelled out we have

x = 16

From the question, At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees

Angle on a straight line is 180° then we can calculate "y" as

y = 180 - (4x - 14)

= 180-4x+14

= 180+14-4x

But x= 16, then substitute we have

= 180 +14 - 14(16)

= 130

Hence, the value of y is 130

Im. lost plese help I suck at Unit Rates
Makovka662 [10]
Luke: 2 miles in 40 minutes, 20 minutes a mile, (2/40 = 20 minutes a mile)
Luke's speed is 3 miles an hour (60minutes/20minutes a mile = 3miles).

Sally: 0.05 miles a minute, 60 minutes in an hour, 60 x 0.05 = 3 miles an hour.  Or 0.05 miles a minute, 40 minutes walked, 40 x 0.05 = 2 miles walked.

There are a few other ways to show that they are accurate rates. 

So yes, they are both correct rates.

Find the value of x need help
amm1812

Answer:

x=-10

Step-by-step explanation:

since there's a given 120 degrees, and it's a isosceles triangle, we know that the line adds up to 180 (where the 120 degrees is). so 120+x=180, the interior angle measures 60 degrees. That being said, the 3 angles measure 60 degrees also. now there's a right angle mark on top, so we find the angle of the smaller triangle (near angle 2) by doing 90-60=30 degrees.

angle 2 is said to be x+160, and there's a line, which tells us that they must add to 180.. so x+160+30=180

x+190=180

x=-10.
