Find the surface area of the prism , need help and steps fast please!!

Answer:

D. 41°

Step-by-step explanation:

[tex](3x + 9) \degree = 132 \degree \\ (vertical \: \angle s) \\ 3x + 9 = 132 \\ 3x = 132 - 9 \\ 3x = 123 \\ x = \frac{123}{3} \\ x = 41 \\ \\ \because m\angle QRS =x\degree \\\therefore m\angle QRS = 41\degree [/tex]

Answer:

  21.07

Step-by-step explanation:

The tangent ratio is ...

  Tan = Opposite/Adjacent

For the given values, this is ...

  tan(36°) = x/29

Solving for x, we have ...

  x = 29·tan(36°)

  x ≈ 21.07

Answer:

A) £650 = $1053

B) $405 = £250

Step-by-step explanation:

For a) Since £1 is equal to $1.62 you would just do £650 times 1.62 to get $1053

For b) Since £1 is equal to $1.62 you would do $405 divided by 1.62 to get £250

Answer:

  angle L = 106°

Step-by-step explanation:

Opposite angles in an inscribed quadrilateral are supplementary.

  ∠L = 180° -∠N

  ∠L = 180° -74° = 106°

Answer:

y > 2

Step-by-step explanation:

1) [tex]3(y+5)>21[/tex]

Divide both sides by 3.

2) [tex]y+5>7[/tex]

Move the constant to the right side and change it's sign.

3) [tex]y>7-5[/tex]

Subtract the numbers.

4) [tex]y>2[/tex]

Answer:

C: 4 hours

Step-by-step explanation:

Mean = Σxn/n

Σx/n = ((2 × 4) + (3 × 5) + (4 × 6) + (5 × 3) + (6 × 3) + (7 × 0) + (8 × 1))/(4 + 5 + 6 + 3 + 3 + 0 + 1)

Σx/n = 88/22

Σx/n = 4 hours

Answer:

c is the answer

Step-by-step explanation:

Answer:

Step-by-step explanation:

First put the numbers from least to greatest: 1, 2, 2, 2, 3       2 is the mean.

Then you determine the distance each data value is from the mean.

1, 2, 2, 2, 3

1, 0, 0, 0, 1

Calculate the mean of the distances:  1 + 0 + 0 + 0 + 1 = 2

Then divide:  2 divided by 5 = 0.4

So your answer is 0.4 pound; on average, the weight of a box varies 0.4 pounds from the mean of 2 pounds

Answer:

The answer is "0.9184".

Step-by-step explanation:

This problem is assisted by data analysis:

Its overview hypothesis test to two sample proportions:

[tex]p_1 :[/tex]percentage of population contributions 1

[tex]p_2:[/tex]percentage of population contributions 2

[tex]\to p_1 - p_2:[/tex] proportion difference

[tex]\to H_0 : p_1 - p_2 = 0\\\\\to H_A : p_1 - p_2 ? 0[/tex]

Calculating the Hypothesis test values:

[tex]Diff \ \ Count1 \ \ Total1 \ \ Count2 \ \ Total2 \ \ Sam. Diff. \ \ Std. Err.\ \ Z-Stat \ \ P value\\\\[/tex]

[tex]p_1 - p_2\ \ 10\ \ 108\ \ 20\ \ 208\ \ -0.0035612536\ \ 0.034766147\ \ -0.10243452 \ \ 0.9184[/tex]

So, the [tex]P - value = 0.9184[/tex]

Step-by-step explanation:

Answer:

Nathan is 36.3910059 ft from the base of the lighthouse.

Step-by-step explanation:

So to find the base, you have to find the tan (both legs) of the right triangle that the lighthouse makes. The angle of Nathan to the lighthouse is 74° so to find the distances, you have to do the tan(72) = opp/adj

The opposite is 112, and we have to find the adjacent.

tan(72) = 112/adj

3.07768354 = 112/adj

adj = 112/3.07768354

adj = 36.3910059

Answer:

Step-by-step explanation:

Plot the given points and connect in pairs to get a triangle.

Visually we can say it is a right triangle as legs TD and ED seem perpendicular.

Let's confirm this by finding the slopes.

Slope of TD:

Slope of ED:

Product of the slopes is:

This confirms DT⊥ED

Correct choice is B
