The temple at the top of pyramid is approximately 24 meters above the ground, and there are 91 steps leading up the temple. How
slamgirl [31]

Answer:

13.187 meters

Step-by-step explanation:

Basically, there are 24 meters for every 91 steps: \frac{24}{91}

There are x meters for every 50 steps: \frac{x}{50}

\frac{24}{91} =\frac{x}{50}

Cross multiply

91x = 1200

Divide both sides by 91 to isolate the variable, x

91x/91 = 1200/91

x = 13.186813

Parker reviews his homework before he turns it in. When he sees the equation 1.02 divided by 0.6= 0.17, he knows it is wrong. He
HACTEHA [7]

Answer:

The result of the division of a number by a fraction is larger than the fraction.

Step-by-step explanation:

Here,we note that value Parker divided by 0.6. =1.02

Written down result of the division = 1.02/0.6 = 0.17

However, since the numerator is 1.02, then the result of dividing it by a fraction should yield a higher number instead of 0.17

Therefore we check as follows

1.02/0.6 = 1.7

The error is apparently due to dividing 1.02 by 6 rather than 0.6
