V = l X w X h
V = 12 X 20 X 14

12 X 7 = 84
84 X 2 = 168

168 X 20 = 3360

The volume of the cooler is 3,360 in³

Find the surface area of the cylinder. Round your answer to the nearest tenth.<br> 6 ft<br> 15 ft
lys-0071 [83]

Answer:

the surface area is 791.3

Step-by-step explanation:

the equation to find the surface area of a cylinder is A=2πrh+2πr^2

A=2*3.14*6*15+2*3.14*6^2

A=6.28*6*15+6.28*36

A=37.68*15+226.08

A=565.2+226.08

A=791.28

rounded to the nearest tenth it would be 791.3

What is the slope-intercept form for each equation in this system? Compare the slopes and y-intercepts to describe the graph of
Yuliya22 [10]

Answer:

We can compare slopes and y-intercepts. The first equation has m=3/4 and b=7. The second has m=-2/5 and b=2. They are intersecting lines.

Step-by-step explanation:

These equations are in the standard form of a line. We can convert to the slope-intercept by solving for y.

3x-4y=28\\-4y=28-3x\\\frac{-4y}{-4} =\frac{28-3x}{-4} \\

y=-7+ \frac{3}{4} x

We can now convert the second equation.

4x+10y=20\\10y=20-4x\\\frac{10y}{10}=\frac{20-4x}{10}

y=2-\frac{4}{10}x

y=2-\frac{2}{5}x

We can compare slopes and y-intercepts. The first equation has m=3/4 and b=7. The second has m=-2/5 and b=2. They are intersecting lines. This eliminates A and B. The answer based on the information given is likely D.

Please answer this in two minutes
Firdavs [7]

Answer:

tan(X) = 1.05

Step-by-step explanation:

The triangles WXY and VTU are similar using the case AA (angle-angle).

The angle X is equal the angle T, therefore they have the same tangent value.

The tangent value is given by the opposite side to the angle divided by the adjacent side to the angle, so we have that:

tan(T) = UV / UT

tan(T) = 21 / 20 = 1.05

tan(X) = tan(T) = 1.05
