55ft²

Answer:

Solution given:

the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2

=base area *2 laternal faces area

=25+2*15=25+30=55ft²

Let the number of visits equal x.

Multiply the number of points by the points per visit.

2.5x

Add that to the points he got for signing up:

2.5x + 35

This needs to equal the total points needed:

2.5x + 35 = 70

Solve for x:

Subtract 35 from both sides:

2.5x = 35

Divide both sides by 2.5:

X = 14

He needs 14 visits

Answer:

angle one and angle three are vertical

Answer:

8 eggs.

Step-by-step explanation:

[tex]\frac{\frac{3}{4} }{1}(8)=\frac{6}{8}[/tex]

Therefore, if you use 6 cups of milk, you should use 8 eggs.

Answer:

6 or 8 is the answer you choose

Answer:

[tex]54\:\mathrm{km/h}[/tex]

Step-by-step explanation:

Average speed is given by [tex]S=\frac{d}{t}[/tex], where [tex]d[/tex] is distance and [tex]t[/tex] is elapsed time.

Since we want the average speed of the entire trip, we need to total distance of the entire trip and the total time it takes for the entire trip.

What we know:

Substituting known values, we get:

[tex]S_{avg}=\frac{108\:\mathrm{km}}{2\:\mathrm{h}}=\boxed{54\:\mathrm{km/h}}[/tex]

Answer:

[tex]3x = 90 \\ x + y = 90 \\ x + y + z = 360[/tex]

Answer:

v = 628.32 m³

Step-by-step explanation:

v = πr²h/3

v = π(20/2)²(6)/3

v = π(100)(2)

v = 628.318530718

Rounded

v = 628.32 m³

Honestly, I'm not sure how to answer this, but I think this can help you.

Well if 5 and 2 fifths is one third of the total height of the building, then that means to find the total height of the building you need to times 5 2/5 by 3.

Answer:

 √90

Step-by-step explanation:

a² + b² = c²

3² + 9² = c²

9 + 81 = 90²

90 = c²

Answer:

B) [tex]x=\sqrt{90}[/tex]

Step-by-step explanation:

Pythagorean thm formula:

a² + b² = c²

Given:

a = 9

b = 3

c = x

Work:

a² + b² = c²

9² + 3² = x²

81 + 9 = x²

90 = x²

[tex]\sqrt{x^2} =\sqrt{90} \\x=\sqrt{90}[/tex]

Answer:

J all rational numbers are real numbers

Step-by-step explanation:

Answer:

b = 42° and c = 180-42 = 138°

Answer:

b) 42°

c) 138°

Step-by-step explanation:

Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.

Hope this helps! Have a wonderful rest of your day!

Answer:

RECTANGLE

Explanation:

Answer:

Rectangle

Step-by-step explanation:

If its sliced perpendicular from its circle base, that means its cutting vertically from it since perpendicular lines form a 90 degree angle.

Answer:

First add 4 to each side

Step-by-step explanation:

7x−4≤19

First add 4 to each side

7x−4+4≤19+4

7x≤23

Then divide by 7

7x/7≤23/7

x≤23/7

Answer:

The answer is 60

Step-by-step explanation:

What you need to do to get this is multiply 12 x 5, I got the 12 from counting the base of the prism and I got the five from counting the height so 12 x 5 = 60

Hope this helps!!!

Answer:

Crayola Classic: 5 Packs; Crayola Tropical: 4 Packs

Step-by-step explanation:

Keep multiplying by both until you get a number equal to eachother

1. 8 x 2 = 16,  10 x 2 = 20

2. 8 x 3 = 24, 10 x 3 = 30

You may notice that the numbers are getting farther apart. This is normal because the boxes are not equal and are getting multiplied further. That means that your answer will have different factors in both the equations.

3. 8 x 4 = 32, 10 x 4 = 40

4. 8 x 5 = 40

Both of those equations (in bold) have the same answer and he wanted the same crayons from both. So, the answer is:

10 x 4 = 40

8 x 5 = 40

(how much packs of each you need to get the same amount)

Hope this helps :)

Answer:

I think it's A.

Answer:

∠1 and ∠5

Step-by-step explanation:

Angles 2, 3 and 4 are taking up 180 degrees because it is 1/2 of a circle. That means angles 1 and 5 are also taking up 180 degrees because both the angles add up to a straight line

Answer:

I hope you will understand my explanation

Step-by-step explanation:

Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: 60° and 120° are supplementary angles.
