Petra jogs 5 miles in 40 minutes. At this rate, how long would it take her to jog 10 miles?

2 answers:

8 0

So, you divide 40 by 5 to see how many miles per minute Petra jogs. Then, you take that answer and multiply it by 10 to find out how long it takes her to jog 10 miles.

80 minutes or 1 hour and 20 minutes. 5 x 2 = 10. If it takes 40 minutes for 5 miles, than 40 x 2 = 80.

Suppose the height of the pyramid is 20 yards. What is the pyramid's volume?

DedPeter [7]

Answer : The correct option is, (B) 1500 cubic yards.

Step-by-step explanation :

Formula used to calculate the volume of square pyramid is:

$V=\frac{a^2\times h}{3}$

where,

V = volume of pyramid

a = base edge of pyramid

h = height of pyramid

Given:

Base edge of pyramid = 15 yards

Height of pyramid = 20 yards

Now putting all the given values in the above formula, we get:

$V=\frac{a^2\times h}{3}$

$V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}$

$V=1500\text{ yards}^3$

Therefore, the volume of pyramid is 1500 cubic yards.

Find tan if sin theta= 1/4 and falls in Quadrant 2.

7nadin3 [17]

If sinα=1/4 and it is in q2 it means that the x coordinate is negative.

The triangle has a height of one and a hypotenuse of 4 so:

x=-√(4^2-1)

x=-√15

so tanα=-1/√15

tanα=-√(1/15)

tanα≈ -0.258
