Find the value of x.

13,15,17,x,20,21; The median is 18.

Answers

Answer 1
Answer:

Answer:

1

Step-by-step explanation:

13  15  17  x  20  21

Cross out all outer numbers

We are left with 17 and x

With double medians, you add those two together and then divide them by two.

With the median (total) being 18, we will first add 17+x then divide Y/2 = 18

The value of x is 1

Joseph uses 30 grams of sugar and 24 grams of butter.a) how many times the amount of sugar is the amount of butter?
b) how many times the amount of butter is the amount of sugar?

Answers

Answer:

(a ) 1.25 times.

(b) 0.8 times.

Step-by-step explanation:

We have been given that Joseph uses 30 grams of sugar and 24 grams of butter.

(a) To find the amount of sugar is how many times the amount of butter, we need to find 30 is what part of 24.  

(30)/(24)=(5)/(4)=1.25

Therefore, the amount of sugar is 1.25 times the amount of butter.

(b) To find the amount of butter is how many times the amount of sugar, we need to find 24 is what part of 30.  

(24)/(30)=(4)/(5)=0.8

Therefore, the amount of butter is 0.8 times the amount of sugar.

Answer:

check step by step

Step-by-step explanation:

A) 30 divided by 24

B) 24 divided by 30

Use DE←→ and FG←→ to answer the question. DE←→ contains the points D(1,−2) and E(3,4). FG←→ contains the points F(−1,2) and G(4,0). Is DE←→ perpendicular to FG←→? Why or why not? A.No, because the product of the slopes is not −1. B.Yes, because the product of the slopes is −1. C.No, because the product of the slopes is not 1. D.Yes, because the product of the slopes is 1.

Answers

Answer:

A. No, because the product of the slopes is not -1

Step-by-step explanation:

The slope of a line that passes through points (x1, y1) and (x2, y2) is computed as follows:

m = (y2 - y1)/(x2 - x1)

Therefore:

  • Slope of DE (m1) = (4 - (-2))/(3 - 1) = 3
  • Slope of FG (m2) = (0 - 2)/(4 - (-1)) = -0.4

Two lines are perpendicular if the product of their slopes is equal to minus one. In this case, m1*m2 = 3*(-0.4) = -1.2 ≠ -1

Answer:

Yes, because the product of the slopes is −1.
