A rectangular pyramid has a base with dimensions 5 inches by 7 inches. The height of the pyramid is unknown. If the volume of th

Ksenya-84 [330]

Answer:

The height of the pyramid is $9\ in$

Step-by-step explanation:

we know that

The volume of the rectangular pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the rectangular base of the pyramid

H is the height of the pyramid

$B=5*7=35\ in^{2}$

we have

$V=105\ in^{3}$

substitute the value of B and the value of V in the formula and solve for H

$105=\frac{1}{3}(35)H$

$315=(35)H$

$H=315/35=9\ in$

Another path in the community is 2.4 miles long. It has benches at 1/3 And 2/3 of the distance from beginning to end of the path

antoniya [11.8K]

Answer:

the benches are 0.8 and 1.6 miles from the ends of the path

Step-by-step explanation:

The first bench is 1/3 of the path's length from the beginning of the path:

(1/3)×(2.4 mi) = (2.4/3) mi = 0.8 mi

The second bench is 2/3 of the path's length from the beginning of the path:

(2/3)×(2.4 mi) = (2.4×2/3) mi = 4.8/3 mi = 1.6 mi

The benches are 0.8 mi and 1.6 mi from the beginning of the path.

_____

Of course, 0.8 mi from the beginning is 2.4-0.8 = 1.6 mi from the end, and vice-versa.

For a circle with a radius of 6 feet, what is the measurement of the central angle (in degrees) that intercepts an arc with a le

makkiz [27]

Answer:

135 degrees

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=6\ ft$

substitute

$C=2\pi (6)$

$C=12\pi\ ft$

step 2

Remember that the circumference of the circle subtends a central angle of 360 degrees

using proportion

Find out the measurement of the central angle (in degrees) that intercepts an arc with a length of 9π/2 ft

$\frac{12\pi}{360^o}=\frac{(9\pi/2)}{x}\\\\x=360(9\pi/2)/12\pi\\\\x=135^o$
