Answer:

Step-by-step explanation:

the wall meets the at a 45 degree angle and because of this we can draw a traingle allowing us to use the 45,45,90 method so then we do 12 times 2 and we get 24

A tank in the shape of a right rectangular prism measures 10 inches long, 5 inches wide, and 7 inches tall. The tank is filled w

fgiga [73]

Answer:

Approximately 149 cubic centimeters of water

Step-by-step explanation:

step 1

Find the volume of water in the tank

The volume of a rectangular prism is equal to

$V=LWH$

we have

$L=10\ in\\W=5\ in\\H=7\ in$

substitute

$V=(10)(5)(7)=350\ cm^3$

step 2

Find the volume of the cylindrical container

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=4/2=2\ in$ ---> the radius is half the diameter

$h=1.6\ in$

$\pi =3.14$

substitute

$V=(3.14)(2)^{2}(1.6)$

$V=20.096\ cm^3$

step 3

To find out how much water is still in the tank, subtract the volume of 10 containers of water from the volume of the tank

$350-(10)(20.096)=149.04\ cm^3$

therefore

Approximately 149 cubic centimeters of water

Given the speeds of each runner below, determine who runs the fastest.

Lesechka [4]

Answer:

Debbie runs 9 feet per second: 9 ft/s

Jessica runs 1 mile in 440 seconds: 414/50 ft/s = 207/25 ft/s = 8 7/25 ft/s

jesssica runs 131 feet in 10 seconds: since 1 mile = 5280 ft we have 1/470 mi/s = 5280/470 ft/s = 528/47 ft/s = 11 11/47 ft/s

ron runs 603 feet in 1 minute: 547 ft/min = 603/60 ft/s = 201/20 ft/s = 10 1/20 ft/s

Since:

11 11/47 > 10 1/20 > 9 > 8 7/25

Emily runs the fastest.
