The net of a solid is shown below: Net of a square pyramid showing 4 triangles and the square base. The square base has side lengths of 3 inches. The height of each triangle attached to the square is 4 inches. The base of the triangle is the side of the square. What is the surface area of the solid? WILL GET BRANLIEST! <3

Answers

Answer 1

Answer:

33 sq in

Step-by-step explanation:

Area of each triangular face is 1/2×3×4 = 6sq in

Hence total area of four(4) faces is 6×4 = 24sq in

Area of base is 3×3 = 9sq in

Hence Total area of pyramid is 24+9 = 33sq in

If there are 2 red balls, 2 blue balls, and 4 green balls in a pail, what is the probability of pulling out a green ball?

(step-to-step pls)

Answers

Answer:

Step-by-step explanation:

Step 1 is to find the total number of balls in the pail.

There are 8 balls in total

Now that you know there are 8 balls, you have to find out how many of those 8 are green. This is because you want to pull out a green ball. You would do the same thing for any other colored ball.

Since 4 out of the 8 balls in the pail are green, you can write this as 4/8

The last step is to simplify to get 1/2 which in other terms is 50%.

So the probability of you pulling a green ball is 50%

It’s 50 percent chance of pulling out a green ball.

The answer is 2. 60 miles per hour.
Unit rate is a ratio that compares two different quantities with different units.
Choice 2 is the only right one since it’s miles per hour. Choice 1 and 3 are just simple ratios with no units.

Answers

Answer:

Step-by-step explanation:

4(6−2x)−3(3−4x)

Distribute:

=(4)(6)+(4)(−2x)+(−3)(3)+(−3)(−4x)

=24+−8x+−9+12x

Combine Like Terms:

=24+−8x+−9+12x

=(−8x+12x)+(24+−9)

=4x+15

Hey there!

“ Simplify 4(6 - 2x) - 3(3 - 4x)”

FIRST: you have to DISTRIBUTE

4(6) + 4(–2x) + (–3)(3) + (–3)(–4x)

4(6) = 24

4(–2x) = –8x

–3(3) = –9

–3(–4) = 12x

NEW EQUATION: 24 – 8x – 9 + 12x

SECOND: COMBINE your LIKE TERMS

(24 – 9) + (–8x + 12)

24 – 9 = 15

–8x + 12 = 4x

OR........ (MAINLY this one )

(–8x + 12) + (24 - 9)

(–8x + 12) = 4x ⬅️ FRONT NUMBER

24 – 9 = 15 ⬅️ BACK NUMBER

The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle.
(2x+18)°
55°
(4x+11)°

Answers

Answer:

(2x+18) degrees

Step-by-step explanation:

A triangle is a total of 180 degrees, so you would do:

(2x+18)+55+(4x+11)=180

(2x+4x)+(18+55+11)=180           <- take out parentheses and add like terms

6x+84=180                         <- subtract 84 from both sides of the equation

6x=96                                    <- divide 6 from each side

x=16

Now that you know what x is you would plug it into each of the angles

Angle 1: 2x+18 --> 2(16)+18= 32+18= 50

Angle 2: 55

Angle 3: 4x+11 --> 4(16)+18= 64+18= 82

Then out of these three angles of the triangle, angle 1 (2x+18) would be the smallest.

Multiply both sides by 9

2x > -144
