Answer:

Option C. Transitive property of equality

Step-by-step explanation:

It is given in the question AB ≅ CD and CF ≅ EB

and we have to prove that AE ≅ FD

Since AB = AE + EB

and CD = CF + FD

AB ≅ CD [Given]

So, AE + EB ≅ CF + FD

Since CF ≅ EB [Given]

So, AE ≅ FD [Transitive property]

Hence Option C. Transitive property of equality will be the answer.

svp [43]

Answer:

1 and 2/5 yards wastes only 1/15 a yard

Step-by-step explanation:

1 and 1/6 yards would make a waste of 1 and 1/6 yards since you can't make a ribbon out of it. (incorrect)

1 and 2/10 yards would make a waste of 1 and 1/5 yards since you can't make a ribbon out of it. (incorrect)

1 and 2/5 yards

$1\frac{2}{5} -1\frac{1}{3} =\\\\1\frac{6}{15} -1\frac{5}{15} =\\\\\frac{1}{15}$

Wastes 1/15 a yard.

1 and 1/2 yards

$1\frac{1}{2} -1\frac{1}{3} =\\\\1\frac{3}{6} -1\frac{2}{6} =\\\\\frac{1}{6}$

It wastes 1/6 a yard.

2 yards

$2-1\frac{1}{3} =\frac{2}{3}$

It wastes 4/6 a yard.

Shen started to run on a treadmill after setting its timer for 93 minutes. The display says that he has finished 69% of his run.

djverab [1.8K]

Answer:

64.2 minutes

Step-by-step explanation:

We are given that

Shen set timer to run=93 minutes

He has finished his run=69%

We have to find total number of minutes have gone by.

69% of 93

= $\frac{69}{100}\times 93$

By using

a% $=\frac{a}{100}$

69% of 93= $\frac{6417}{100}$

69% of 93=64.17 min

69% of 93 $\approx 64.2min$

Hence, 64.2 minutes have gone by.

800 hm = _____ cm 8 0.08 8,000,000 80,000

il63 [147K]

To solve this conversion factor problem we are going to multiply our original quantity 800hm by conversion factors (expressed as fractions) in order to cancel units until we get centimeters:
We know that 1 hectometer= 100 meters, so our first conversion factor expressed as a fraction is $\frac{100m}{1hm}$
We also now that 1 meter = 100 centimeters, so our second one is $\frac{100cm}{1m}$

Now that we have our fractions, lets multiply our original quantity by them to get our answer in the required units:
$800hm( \frac{100m}{1hm} )( \frac{100cm}{1m})=8000000cm$

We can conclude that 800hm are 8,000,000cm
