20% of the students in Mrs. Smith's class are in art club, how many students are in the entire class?

Answer:

please mark brainlyest

6 = 200

12 = 400

18 = 800

24 = 1600

30 = 3200

36 = 6400

42 = 12800

48 = 25600

In theory assuming none of them die and they reproduce at a constant rate.

Answer:

x > 3

Step-by-step explanation:

Step 1: Subtract 7 from both sides.

Step 2: Divide both sides by 3.

Therefore, the solution is x > 3.

Answer:

[tex]\displaystyle 3 < x[/tex]

Step-by-step explanation:

[tex]\displaystyle 3x + 7 > 16 \hookrightarrow \frac{3x}{3} > \frac{9}{3} \\ \\ x > 3[/tex]

The above answer is written in reverce, and is still the same result.

*Now, in case you did not know how we arrived at the division, seven was deducted from both sides of the inequality to give you [tex]\displaystyle 3x > 9.[/tex]From there, we splat both sides in third to give you the above result.

I am joyous to assist you at any time.

Answer:

you will save 7.50$ and the sales price will be 42.50$

Step-by-step explanation:

15% of 50 is 7.5

Part A:

(26)x = 1

Solve for x by dividing both sides by 26:

X = 1/26

part B:

(50)x = 1

Solve for x by dividing both sides by 50:

X = 1/50

[tex]\\ \rm\Rrightarrow 26x=1[/tex]

[tex]\\ \rm\Rrightarrow x=1/26[/tex]

#B

[tex]\\ \rm\Rrightarrow 50x=1[/tex]

[tex]\\ \rm\Rrightarrow x=1/50=0.02[/tex]

Answer:

4π cm²

Step-by-step explanation:

The area of a circle is [tex]\pi r^2[/tex], where r = radius. We're given the radius as 2 centimeters, and we have to solve in terms of pi.

Therefore, the answer is 4π cm².

Answer:

150%

Step-by-step explanation:

40 euro = 100% change

20 / 2 = 10 (50% of 20)

Add them

40 + 10 = 500

100 + 50 = 150

150%

Answer:

The volume will be multiplied by 8.

Step-by-step explanation:

If the sides are doubled, what is going to happen to the volume? First, let's find out what the initial volume is first!

The side lengths are 2 meters. With squares/cubes, all sides are equal.

So, the length, height, and width are the same.

For the volume, we need to multiply those values.

2*2*2=8 meters

That's the initial volume.

Now, let's find out what the volume will be once we've double the side values.

2*2=4

The side values are now four.

Let's multiply!

4*4*4=64 meters

It looks like the volume multipled by eight fold.

Answer:

D

Step-by-step explanation:

Lateral SA = area of the 4 triangles

Formula to be used :-

Area (triangle) = 1/2bh

=> 4 x 1/2 x 9 x 12

=> 108 x 2

=> 216 cm²

Total SA = LSA + area of the square

Formula to be used :-

Area (square) = side length x side length

=> 216 + 9 x 9

=> 216 + 81

=> 297 cm²

The correct option is (D).

LSA:-

Area of one triangle:-

LSA

TSA:-

Area of square:-

TSA:-

The volume of the cone is [tex]\frac{1}{3} \pi r^{2}h[/tex]

Volume = [tex]\frac{1}{3} \pi (6)^{2} *6=226.08ft^{3}[/tex]

Answer:

Step-by-step explanation:

4 and 25

The value of  ∠EBD is 66°

Vertical angles are a pair of opposite angles formed by intersecting lines. Vertical angles are equal. Therefore,

∠EBA≅∠CBF

Therefore,

∠EBA = 40 - x

∠EBA  + ∠EBD = 90°(complementary angles)

Therefore,

40 - x + 6x - 30 = 90

5x = 90 + 30 - 40

5x = 80

x = 80 / 5

x = 16

Therefore,

∠EBD = 6(16) - 30 =  66°

Answer:

120.25

Step-by-step explanation:

4 to the third power is 64. so 64 + 9 = 83. 20-8 = 18. 6 + 2 = 8.

so 83 + 18 + 8 = 109. so 8 divided by 18 = 2.25. 109 + 9 + 2.25 = 120.25.

3(x + 5)

The distributive property states that you are distributing whatever is outside the parenthesis to all terms within the parenthesis. For complex distributive questions, you will have to simplify the parenthesis first (if you can) before distributing.

In this case, the example given is 3(x + 5).

First, distribute 3 to all terms in the parenthesis by multiplication:

3(x + 5)

= (3 * x) + (3 * 5)

= 3x + 15

3x + 15 is your answer.

~

Another more complex distribute property can involve powers. Take for example:

(7x + 5)²

In this case, you will use the distributive method of FOIL, or (First, Outside, Inside, Last). Set the question:

(7x + 5)² = (7x + 5)(7x + 5)

First: 7x * 7x = 49x²

Outside: 7x * 5 = 35x

Inside: 5 * 7x = 35x

Last: 5 * 5 = 25

Next, combine like terms:

49x² + 35x + 35x + 25

49x² + (35x + 35x) + 25

49x² + (70x) + 25

49x² + 70x + 25 would be your answer.
