Answer:

x = 18

Step-by-step explanation:

The line joining 2 midpoints of the non parallel sides of a trapezoid is 1/2 the sum of the two parallel lines.

Put in much simpler language XY = 1/2 (BC + AD)

4x - 2 = 1/2 (6x + 1 + x)                         Combine the right

4x - 2 = 1/2 (7x + 1)                               Multiply by 2

8x - 4 = 7x + 1                                       Add 4 to both sides

8x = 7x + 5                                           Subtract 7x

x = 5

But what you want is the length of XY

XY = 4x - 2 = 4*5 - 2 = 18

Sorry I noticed too late that I used x for s. The answer would still be 18.

the answer would be x = 18

8 1/5-2 7/8 fractions

Answers

i removed my answer because it was wrong look at the other peoples answers

Answer: 213/40 or 5.325

Step-by-step explanation:

We can find common denominators for 8 1/5 and 2 7/8.

The Lowest Common Denominator for 8 1/5 and 2 7/8 is 40.

8 1/5 = 41/5 = 328/40.

2 7/8 = 23/8 = 115/40.

Now we can subtract.

328/40 - 115/40 = 213/40.

Therefore, the answer is 213/40 or 5 13/40.

Of the last 60 people who went to the cash register at a department store, 15 had BLOND hair,
17 had BLACK hair, 26 had BROWN hair, and 2 had RED hair. Determine the experimental
probability that the next person to come to the cash register has BLOND hair. (answer as
simplified fraction)

Answers

Answer:

[tex]P(Blond) = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]Total = 60[/tex]

[tex]Blond = 15[/tex]

[tex]Black = 17[/tex]

[tex]Brown = 26[/tex]

[tex]Red = 2[/tex]

Required:

Determine the experimental probability of the next person having blond hair

This is calculated by dividing the number f people having blond hair with the total number of people.

i.e.

[tex]P(Blond) = \frac{Blond}{Total}[/tex]

[tex]P(Blond) = \frac{15}{60}[/tex]

Simplify

[tex]P(Blond) = \frac{1}{4}[/tex]

We have 5 * 70 split up into multiple ways, and we need to provide an answer at the end of it.

5 * 70 = 5 * (__ * 10)

We have to equal the value of 5 * 70 by inputting the missing number.

Zoey's dog has a water bowl with a diameter of 6 inches. Sam's
dog has a water bowl with a diameter of 10 inches. What is the
approximate difference in the circumference (distance around)
ut of the two water bowls?

Answers

Answer:

12.56 inches

Step-by-step explanation:

Circumference: C = 2*pi*r

I will be using 3.14 in place of pi

Divide the diameters by 2, so 3 for Zoey and 5 for Sam

Multiply (2*3.14*3) and (2*3.14*5)

For Zoey you get 18.84 and for Sam you get 31.4

31.4-18.84= 12.56 in difference
