Find the surface area of the figure. Round to the nearest tenth if possible.

Cloud [144]

Area of square base:
13 x 13 = 169
Area of triangular sides:
B x H/2
13 x 16/2 = 104
104 x 4 = because there are 4 triangular sides of the figure = 416
416 + 169 = 585in^2
590in^2

Find each missing angle of the trapezoid

zimovet [89]

Answer:

∠J = 107°

∠K =107°

∠L = 73°

∠M = 73°

Step-by-step explanation:

Angle J + angle M = 180°

(10x - 33) + (4x+17) = 180

simplify:

14x -16 = 180

14x = 196

x = 14

∠J = 10(14) - 33 = 107°

∠M = 4(14) + 17 = 73°

Equation Given: <img src="https://tex.z-dn.net/?f=h%28t%29%3D-4.9t%5E%7B2%7D%2B358" id="TexFormula1" title="h(t)=-4.9t^{2}+358"

Vilka [71]

Answer:

At 3.44 seconds, the penny is at a height of 300 meters above the ground.

Step-by-step explanation:

Basically, we have to solve an equation here:

$-4.9t^{2} + 358 = 300$

Hence,

$-4.9t^{2} = 300 - 358$

$t^{2} = \frac{-58}{-4.9}$

$t = 3.44$

Hence, at 3.44 seconds, the penny is at a height of 300 meters above the ground.

Hope this helped!

Bryce tried to solve an equation step by step.

Aloiza [94]

$$c=\frac{1}{3}$

Solution:

Given equation is $\frac{8}{3}=3c+\frac{5}{3}$ .

To solve the equation by step by step.

Step 1: Given

$\frac{8}{3}=3c+\frac{5}{3}$

Step 2: Combine like terms together.

Plus symbol changed to minus when the term goes from right to left (or) left to right of the equal sign.

$\frac{8}{3}-\frac{5}{3}=3c$

Step 3: Subtract the fractions in the left side.

$\frac{3}{3}=3c$

⇒ $1=3c$$

Step 4: Divide both side of the equation by 3, we get

$\frac{1}{3} =\frac{3c}{3}$

$\frac{1}{3} =c$

Hence, the answer is $c=\frac{1}{3}$ .
