Can someone please tell me how to find the surface area of shapes please I'm literally crying I have a quiz due in 10 minutes and I'm gonna fail please help

The area of the base is 1/2 x s x s = 1/2 x 12 x 12 = 72 square cm

Volume = area of base x height/3

Volume = 72 x 14/3 = 336 cm^3

Answer:

70

Step-by-step explanation:

you add 95 and 15 and get 110 then you do 180-110 getting 70

Answer:

The answer is B. 283.8 miles.[tex]\sqrt{b^2[/tex]

Step-by-step explanation:

Using the cosine rule:

b^2 = a^2 + p^2 - 2ap(cosB)

b^2 = 172.20^2 + 111.64^2 - 2 x 172.20 x 111.64(cos177.29)

b^2 = 42,116.33 - 38,448.82(cos177.29)

b^2 = 42,116.33 - (-38,405.82)

b^2 = 42,116.33 +38,405.82

b^2 = 80,522.15

[tex]\sqrt{b^2[/tex] = [tex]\sqrt{80,522.15}[/tex]

b = 283.76 miles = 283.8 miles

Answer:

the answer is b

i don't know I just do lol

Answer:

The answer is C

Step-by-step explanation:

(-1,-1) when put into both equations are the same thing.

Answer:

0.1 is the outlier

Step-by-step explanation:

Though the question has a missing attachment (of the line plot), the question can still be answered.

The given data can be represented as;

[tex]\begin{array}{cc}{} &{Dots} & {0.1} & {1} & {0.5} & {2} & {0.6} & {4} & {0.7} & {1} \ \end{array}[/tex]

Notice that 0.1 is not as close as to other data as the closeness of 0.5, 0.6 and 0.7.

This implies that 0.1 is an outlier.

Answer:

0.1 is the outlier

Step-by-step explanation:

Look at the data on the line plot.

A line plot shows a number line 0.1 to 0.7 in intervals of 0.1. 0.1 has 1 dot. 0.5 has 2 dots. 0.6 has 4 dots. 0.7 has 1 dot.

Which data value would be considered the outlier? Enter your answer in the box

Answer:

x = 17

Step-by-step explanation:

75 = 4x + 7

68 = 4x

x = 17

Answer:

17

Step-by-step explanation:

Set equal to each other

Subtract 7 from 75

Divided the answer (68) by 4

Receive the answer 17

Hope this helps, have a good day.

Answer:84

Step-by-step explanation:

-8+92

Lo puedes dar la vuelta

92-8= 84

Answer:

84

Step-by-step explanation:

So -8 + 92 = 92 - 8

   92

-     8

______

   84

So, -8 + 92 = 84

hope this helps:)

Answer:

I am not sure on this one, sorry :(

Step-by-step explanation:

The rest of the side where the 8 is would 20 (28-8)

Set up proportions:

8/10 = 20/3x-5

Cross multiply

200 = 24x-40

Add 40 to both sides

240 = 24x

Divide both sides by 24

X = 10

Solve for the equation: 3x-5 = 3(10)-5 = 30-5 = 25

Answer:

B

Step-by-step explanation

f(x)=x2-4x-5

Becomes

f(x)=x2-5x+x-5

Take out the common factor

f(x)=(x-5)(x+1)

Equate the given function equal to 0

0=(x-5)(x+1)

And then

x-5=0 -- x=5

x+1 = 0 == x=-1

Answer:

B

Step-by-step explanation:

we are given a quadratic function

we want to figure out the form which we don't need change

so according to the question

[tex] \displaystyle{x}^{2} - 4x - 5 = 0[/tex]

rewrite -4x as x-5x:

[tex] \displaystyle{x}^{2} + x - 5x- 5 = 0[/tex]

factor out x:

[tex] \displaystyle \: x({x}^{} + 1)- 5x- 5 = 0[/tex]

factor out -5:

[tex] \displaystyle \: x({x}^{} + 1)- 5(x + 1 )= 0[/tex]

group:

[tex] \displaystyle \: (x + 1 )(x - 5)= 0[/tex]

hence our answer is B

Answer:

500m

Step-by-step explanation:

a rectangle has 4 sides, so 30=60 and 20=40

60x5=300

40x5=200

300+200=500

500m

reason of 500

The main reason for this is he ran AROUND the rectangle and did it 5 TIMES, doing it once would be 100m.

Answer:

Answer:

Step-by-step explanation:

Answer:

200π cm^2

Step-by-step explanation:

Sb = 8^2 π = 64π cm^2

a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm

Sl = 8x17xπ = 136 π cm^2

SA = 136π + 64π =200π cm^2

Answer:

100 minutes

Step-by-step explanation:

Given data

Total distaance= 400meters

Speed= 4m/s

We know that the expression for speed is

Speed= distance/time

substitute to find time

4= 400/time

time= 400/4

time= 100 minutes

Answer:

The answer is "[tex]\frac{2}{3}[/tex]"

Step-by-step explanation:

In this question the graph file is missing which is defined in the attachment section please find it.

Let the 18 square boxes are available, 12 of those are in color.

If published in part, it will be

[tex]\to \frac{12}{18}= \frac{4}{6}=\frac{2}{3}[/tex]

There are two colors out of 3 square boxes.

Answer:

5
