Volume = 10,700

V = LWH

L = 29.4

W = 16.7

H = 21.8

All we need to do is multiply them all together and then round the answer to get our final answer to the hundreds place.

V = LWH

V = 29.4(16.7)(21.8)

V = 490.98(21.8)

V = 10703.364

Then, we need to round it to the hundreds place.

V = 10,700

jeka94

Answer:

George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus

Step-by-step explanation:

<u><em>The question is</em></u>

Find how many kilometers they traveled by bike

Let

x ---->  kilometers traveled by bike

y ---->  kilometers traveled by bus

we know that

They traveled 300 kilometers in total

so

x+y=300 ----> equation A

They biked 70 kilometers more than they were bus

so

x=y+70 ----> equation B

substitute equation B in equation A

(y+70)+y=300

solve for y

2y+70=300\\2y=300-70\\2y=230\\y=115

<em>Find the value of x</em>

x=115+70=185

therefore

George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus

C ( n k) = (n₁ k₁) (n₂ k₂) (n₃ k₃) = (4 3)  (9 2)  (7 3) =

(4 · 3 · 2 / 3 · 2 · 1) (9 · 8 / 2 · 1) (7 · 6 · 5 / 3 · 2 · 1) = 4 · 36 · 35 = 5040

It can be done in 5040 ways.

<em>Equations</em>

2L+2W=192

L=3W

<em>Solving/Substitution</em>

2(3W)+2W=192

8W=192

W=192/8=24

L=24*3=72

The length is 72 feet.

How long is a guy wire reaching from the top of a 6ft. Pole to a point on the ground 4ft. From the pole
dlinn [17]

Answer:

the guy wire is 7.211 ft long

Step-by-step explanation:

Notice that we are in the presence of a right angle triangle formed by: the height (the standing 6 ft pole), the base (the distance from the pole to the anchoring point on the ground), and the actual guy wire. See attached image for reference.

Notice that since pole and ground are perpendicular to each other (at 90 degrees) , the guy wire forms what is called the "hypotenuse" (longest side) of the right angle triangle. We can therefore use the Pythagorean Theorem to solve this problem with the formula for the hypotenuse:

Hypotenuse=\sqrt{side1^2 +side2^2} \\Hypotenuse= \sqrt{6^2+4^2}\\Hypotenuse=\sqrt{36+16} \\Hypotenuse=\sqrt{52} \\Hypotenuse=7.2111\, ft
