6th grade math , help me please :)
sleet_krkn [62]

Answer:

A. Eric rode 2 more miles per week than Kim rode

Step-by-step explanation:

Number of miles Kim rode bicycle in 9 weeks = 135 miles

Let x be the number of miles per week.

135miles => 9 weeks

x miles => 1 week

x = \frac{135}{9}

x = 15

Kim rode the bicycle 15 miles per week

Number of miles Eric rode bicycle in 6 weeks = 102 miles

Let x be the number of miles per week Eric rides the bicycle.

102 miles => 6 weeks

x miles => 1 week

x = \frac{102}{6}

x = 17

Kim rode the bicycle 17 miles per week

<em>Comparing the number of miles per week they rode, we would conclude that: "Eric rode 2 more miles per week than Kim rode".</em>

The base of a pyramid is a rectangle with a width of 4.6 cm and a length of 9 cm. What is the height, in centimeters, of the pyr
Sauron [17]

<u>Given</u>:

Given that the base of a pyramid is a rectangle with a width of 4.6 cm and a length of 9 cm.

The volume of the pyramid is 82.8 cubic cm.

We need to determine the height of the pyramid.

<u>Height of the pyramid:</u>

The height of the pyramid can be determined using the formula,

V=\frac{lwh}{3}

Substituting the values, we get;

82.8=\frac{9\times 4.6 \times h}{3}

Multiplying both sides by 3, we get;

248.4=41.4 \times h

Dividing both sides by 41.4, we have;

6=h

Thus, the height of the rectangular pyramid is 6 cm.

Hence, Option A is the correct answer.
