The answer is 988 square inches. L=23 W=10 H=8

The equation for surface area is 2(L x W) + 2(L x H) + 2(W x H)

Next, you need to substitute the values into the equation to get:

Surface area= 2(23 x 10) + 2(23 x 8) + 2(10 x 8)

Now finish solving the equation to get an answer of 988 square inches!

Solve for x. Round your answer to the nearest tenth (0.1)

Marizza181 [45]

Answer:

$x\approx 7.0$

Step-by-step explanation:

Since we are given a right triangle, we can use right trigonometric ratios.

<em>x</em> is the opposite side to our angle. 10 is the adjacent side to it. Thus, we can use the tangent ratio:

$\displaystyle \tan(\theta^\circ)=\frac{\text{opposite}}{\text{adjacent}}$

Substitute:

$\displaystyle \tan(35^\circ)=\frac{x}{10}$

Solve for <em>x:</em>

<em /> $x=10\tan(35^\circ)$ <em />

Use a calculator:

$x=7.0020...\approx 7.0$

What is the slope of the line that passes through the pair of points (1/3, -1) and ( -2, 9/2)

UkoKoshka [18]

Answer:

$\boxed{m = - \frac{33}{14} }$

.

Step-by-step explanation:

Use the form below

$\boxed{\boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }}$

Where

$m$ is a slope
$(x_1,~y_1)$ and $(x_2,~y_2)$ are the point of the line

.

So, the slope is

$(\frac{1}{3} ,~ -1) \to x_1 = \frac{1}{3} ~and~y_1 = -1$

$(-2,~ \frac{9}{2} ) \to x_2 = -2~and~y_2 = \frac{9}{2}$

.

$m = \frac{\frac{9}{2} -(-1)}{-2-\frac{1}{3} }$

$m = \frac{\frac{11}{2} }{\frac{-7}{3} }$

$m = \frac{11}{2} \div (-\frac{7}{3} )$

$m = \frac{11}{2} \times (-\frac{3}{7} )$

$m = - \frac{33}{14}$

.

On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday

Finger [1]

Answer: $-8^{\circ}C$

Step-by-step explanation:

Given

The temperature on Tuesday is $1^{\circ}C$

Temperature drops to $-2^{\circ}C$ on Wednesday

Net drop in temperature $1-(-2)=3^{\circ}C$

The temperature drops twice from Wednesday to Thursday

$\Delta T=2\times 3=6^{\circ}C$

Temperature on Thursday

$\Rightarrow -2-6=-8^{\circ}C$
