(Please Help Will Mark Brainliest) What Is The Total Surface Area Of The Triangular Prism? 30m^260m^275m^263m^2

Answers

Answer 1

Answer:

63m^2

Step-by-step explanation:

Find the area of each base

2.5(10)= 25

1.5(10) = 15

2(10) = 20

Add them together

20 + 15 + 25 = 60

Now find the area of the triangles at each side

2(1.5)(1/2) = 1.5

Since there are two triangles, multiply the area by 2

1.5(2) = 3

Add the areas together

60 + 3 = 63

There's your answer

Answer 2

Answer:

63

Step-by-step explanation:

Atotal= Area of base + Area of lateral= 60+3 =63

2 Area of base = 2 ( 1/2 b h )

= 2( 1/2 2x 1.5 )

= 2( 1.5 )

= 3

3 Area of lateral = 3 bh = 2.5X10 +2X10 +1.5X10 = 25+20+15 = 60

Given:

The figure of two parallel lines MP and QS.

A transversal line KL interests the two parallel lines.

[tex]m\angle KNM =146^\circ[/tex]

To find:

The [tex]m\angle KRQ[/tex].

Solution:

If a transversal line intersect the two parallel lines, then the corresponding angles are congruent and their measures are equal.

In the given figure [tex]\angle KRQ[/tex] and [tex]\angle KNM [/tex] corresponding angles. It means their measures are equal.

[tex]m\angle KRQ=m\angle KNM[/tex]

[tex]m\angle KRQ=146^\circ[/tex]

Therefore, [tex]m\angle KRQ=146^\circ[/tex].

Step by step exploration

Answer:

A

Step-by-step explanation:

It's one or the other, so the two on the graph won't connect, and each of them are greater/less than, NOT "or equal to" so both the circles would be closed. When thinking of these, forget about the x and just read greater than 5. On a graph the greater numbers are to the right, so the arrow would be pointing that way

Kirk drew a scale drawing of a petting zoo. The scale he used was 8 centimeters : 5 meters. The goat pen is 24 centimeters long in the drawing. How long is the actual pen?

Answers

The actual length of the pen is 15 meters

How to determine the actual length of the pen?

The given parameters can be represented using the following ratio

Ratio = 8 centimeters : 5 meters

The scale length of the goat pen is given as

Scale length = 24 centimeters

So, we have

24 centimeters : Actual length = 8 centimeters : 5 meters

Rewrite as

24 : Actual length = 8 : 5 meters

Express as fraction

Actual length/24 = 5 meters/8

Multiply by 8

Actual length = 15 meters

Hence, the actual length of the pen is 15 meters

The TV measures 39 inches tall, and the length of its diagonal is 80 inches. What is the width of the TV? Round your answer to the nearest tenth and label your answer.

Your answer:

Answers

We're assuming the TV is a rectangle, meaning all corners have right angles.

From the given information, we have a right triangle with a height of 39 inches, hypotenuse, of 80 inches, and an unknown base width.

Using Pythagorean's theorem:

[tex]a^2+b^2=c^2[/tex]

[tex]b=\sqrt{c^2-a^2}[/tex]

c = 80 and a = 39

[tex]b=\sqrt{80^2-39^2}[/tex]

[tex]=\sqrt{4879}[/tex]

Using a calculator and rounding to the nearest tenth gives

[tex]\approx 69.8 \text{ inches}[/tex]

Find the solution to the system of equations.

8x – 4y = 16
8x + 4y = 16

x= ___
y= ___

PLS HELP

Answers

Answer:

x =2, y =0

Step-by-step explanation:

First we can add the equations to get rid of the y terms in each.

Adding them results in 16x = 32

Dividing by 16 gives us x=2

Substituting this back into equation 1 gives us 8(2) -4y =16

Simplifying,

16 - 4y =16

-4y = 0

y = 0
