15% of a number is 30. What is the number?
A)4.5
B)20
C)45
D)200​

Answers

Answer 1
15% of 200 is 30

so the answer would be D
Answer 2
The answer is D, 200.

Since the total percentage is 100, you would divide that by 15.

100/15=6.666...7

Then, you would multiply that by 30

6.6666...7*30=200

Simplify your answer and write it as a proper fraction, mixed number, or whole number.

Answers

Answer:

$16

Step-by-step explanation:

$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:

4 x 4 = 16

And you'd get your answer, since 4/4 equals 1 whole.

What are the next 3 numbers in the sequence? 2, 4, 9, 18, 23, 46, 51

Answers

Answer:

         102, 107, 214

Step-by-step explanation:

2

4 = 2×2

9 = 4 + 5

18 = 9×2

23 = 18 + 5

46 = 23×2

51 = 46 + 5

        51×2 = 102

       102 + 5 = 107

       107×2 = 214

Find the height of the trapezoid

Answers

Write A=h(b1+b2)/2, where A represents the trapezoid's area, b1 represents one of the base lengths, b2 represents the other base length and h represents the height. Rearrange the equation to get h alone. Multiply both sides of the equation by 2 to get. 2A=h(b1+b2).

Please answer correctly !!!! Will mark Brianliest !!!!!!!!!!!

Answers

Step-by-step explanation:

since they are in order points p and q are in the middle and points O and R are on the end so they say that OR=36 since you don't know the exact lengths of all of the lengths in the middle from O to R then you multiply 5,6 and 1 by x and add

5x+6x+1x=12x

so then the whole length is equal to the ratio of 12x and also 36 so set those to equal each other

12x=36

x=3

so that is just the ratio and since they are asking for the length of O to Q that means that it is just 5x+6x=OQ

11x=OQ

insert x=3

33=OQ

Hope that helps :)

Art was considered sacred work that gained power as more time and energy was spent making it. Clay and stone were often Olmec artists' materials of choice. The changes the artists made to the clay and stone were symbolic of the metamorphosis of the spirit into a different being. For example, when clay was formed into ceramics it became meaningful. After the ceramic vessels were baked, the Olmec believed the ceramics had the power and life to enable the tribe's spiritual leaders to change into other spirits.According to the excerpt, which of these does clay and stone represent in Olmec art?
