Please assist me with these problems using the 45-45-90 relationship triangles​
TiliK225 [7]

Answer:

see below

Step-by-step explanation:

side opposite 90 angle = x \sqrt{2}

sides opposite 45 angle = x

the multiplication and division by  \sqrt{2} should be self explanatory

1. x = 5, y = 5

2. v = 10, u = 10

3. x = \sqrt{10}, y = \sqrt{5}

4. m = 5, n = \frac{5\sqrt{2} }{2}

5. a = \frac{3\sqrt{2} }{2}, b =  \frac{3\sqrt{2} }{2}

6. a = \frac{3\sqrt{2} }{2}, b =  \frac{3\sqrt{2} }{2}

Cindy and Zoey work at a store. Both girls earn $6.25 per hour
wolverine [178]

Answer:

Step-by-step explanation:

I think this is your full question, right?

<em>Cindy and Zoey work at a store. Both girls earn $6.25 per hour. During a normal week Cindy works 15 hours and  Zoey works 20 hours. The expression 6.25(15) + 6.25(20) can be used to calculate the total amount of money that the  girls earned in one week. Which expression shows another way to calculate the amount of money the girls earn in  one week?  </em>

My answer:

The expression shows another way must be equal to: <em>6.25(15) + 6.25(20)  </em>

<=> 6.25 (15+20)

Because both girls earn the same per hour.

One pattern believe fabric sells for $15 for every 2 yards, and another sells for 37.50 every 5 yards do these fabrics have the
Elenna [48]
We need to find out how much is worth one yard in both fabrics, so we divide $15.00 by 2 and $37.50 by 5:

$15.00 ÷ 2 = $7.50 per yard
$37.50 ÷ 5 = $7.50 per yard

As both prices per yard are the same, the answer is: <span>Yes, these fabrics have the same unit cost.</span>
