Figure ABCD Is A Trapezoid. Findthe Value Of X.3x+3B134x+2ADX = ?

Answers

Answer 1

Answer:

x = 3

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

[tex]\frac{1}{2}[/tex] (3x + 3 + 4x + 2) = 13

[tex]\frac{1}{2}[/tex] (7x + 5) = 13 ( multiply both sides by 2 )

7x + 5 = 26 ( subtract 5 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3

Answers

Answer:

y = 5x - 8

Step-by-step explanation:

The linear equation in slope intercept form :

y = mx + c

m = slope ; c = intercept

m = Rise / Run = (y2 - y1) / (x2 - x 1)

Rise = (y2 - y1) = (12 - (-8)) = (12 + 8) = 20

Run = (x2 - x1) = (4 - 0) = 4

Slope, m = Rise / Run = 20 /4 = 5

Hence,

y = 5x + c

For the points ; y = 12 ; x = 4 ; we could obtain c

12 = 5(4) + c

12 = 20 + c

12 - 20 = c

-8 = c

The equation becomes :

y = 5x - 8

Jim's parents keep a chart on the wall where they mark how much Jim grows each year. When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch. In total, how much did Jim grow in during those two years?

Answers

Answer: 3/4 inch

Step-by-step explanation:

When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch.

His growth during those two years will be:

= 1/4 + 1/2

= 1/4 + 2/4

= 3/4 inch

His growth increased by 3/4 inches.

A bag has sixteen marbles in it. There are four of each color. There
are four red, four blue, four green and four yellow.
What is the probability that you will pull a red marble out of the bag?

Answers

Answer: 25 percent

Step-by-step explanation:

The probability of pulling out a red colored marble is [tex]\frac{1}{4}[/tex] or 25%.

What is probability?

'Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event.'

According to the given problem,

Total number of marbles = 16

Number of red marbles = 4

Probability = [tex]\frac{No of possible outcomes}{Total number of outcomes}[/tex]

The number of possible outcome is the number of red marbles = 4

Total number of outcomes is the total number of marbles = 16

⇒ Probability = [tex]\frac{4}{16}[/tex]

                        = [tex]\frac{1}{4}[/tex]

                        or, [tex]\frac{1}{4}[/tex] × 100

                        = 25%

Hence, the probability of pulling out a red marble is 25%.

2^4/4^2 will be 1, I will explain after answering,

2 x 3^1 = 6

(4 - 2) ^2 = 4

First. Evaluate the exponents in the fraction above

2 x 2 x 2 x 2 = 16

4 x 4 = 16

and 16 over 16 would equal 1 whole

3 to the power of 1 means just 3 so 2 x 3 = 6 (easy multiplication)

Evaluate in the parenthesis first: 4 - 2 = 2 then 2 to the power of 2 would be   2 x 2 = 4

In the diagram, △ABC∼△CDE. Write an equation for line k

Answers

Answer:

Step-by-step explanation:

Line AB is parallel to line CD (k) so they have the same slope.

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

m=(6-0)/(4-0)

m=6/4=1.5

y=mx+b, we know m=1.5 so

y=1.5x+b, and we know it passes through point (4,0) so we can solve for b

0=1.5(4)+b

0=6+b

b=-6 so line k is

y=1.5x-6
