Answer:

x = 5; y = 5

Step-by-step explanation:

One angle is a right angle, so its measure is 90 degrees.

One angle measures 45 degrees, so the unknown angle must also measure 45 degrees.

x and y are opposite two 45-degree angles, so x = y.

In a 45-45-90 triangle, the ratio of the lengths of the sides is

1 : 1 : sqrt(2)

We have

x : y : 5sqrt(2)

x/1 = 5sqrt(2)/sqrt(2)

x = 5

y = 5

The triangles are similar. Find the value of A.

Anastasy [175]

Answer:

D. 10 is your answer.

Step-by-step explanation:

If you look, the triangle is twice as small as the big one, so you take the 20 and divide by 2.

20/2 = 10

D. 10 is your answer.

Consider the expression 16y^2 . Select the correct statement:

tiny-mole [99]

Step-by-step explanation:

Given expression is:

$16y^2$

We will solve each statement one by one to see which statements are correct.

If y=3/4, the values of 16y^2 is 12

Putting y = 3/4 in expression

$16y^2 = 16 *(\frac{3}{4})^2 = 16 * \frac{9}{16} = 9$

If y=1/4, the values of 16y^2 is 2

Putting y = 1/4 in expression

$16y^2 = 16 *(\frac{1}{4})^2 = 16 * \frac{1}{16} = 1$

If y=3/8, the values of 16y^2 is 4/9

Putting y = 3/8 in expression

$16y^2 = 16 *(\frac{3}{8})^2 = 16 * \frac{9}{64} = \frac{9}{4}$

If y=1/8, the values of 16y^2 is 1/4

Putting y = 1/8 in expression

$16y^2 = 16 *(\frac{1}{8})^2 = 16 * \frac{1}{64} = \frac{1}{4}$

If y=2/3, the values of 16y^2 is 3/4

Putting y = 2/3 in expression

$16y^2 = 16 *(\frac{2}{3})^2 = 16 * \frac{4}{9} = \frac{64}{9}$

Hence,

The correct statement is:

If y=1/8, the values of 16y^2 is 1/4

An outdoor spigot at the school has a leak and is dripping water. A student counted eighty drops of water in five minutes and no

lianna [129]

Answer:

D. 108 liters

Step-by-step explanation:

Given that the leak is ;

5 drops = 5 minutes

?= 4 weeks

Find number of hours in 4 weeks

1 week=7days

4 weeks=?--------------cross multiply

4×7=28 days

1 day=24 hours

28 days=?--------------cross multiply

28×24=672 hours

Hour= 60 minutes

672 hours=?

672×60=40320 minutes

Finding the leakage in 4 weeks

80 drops= 5 minutes

?=40320 minutes------------cross multiplication

(40320×80)÷5 =645120 drops

Finding the liters of water wasted in 4 weeks

60 drops of water= 10 milliliters

645120 drops of water=?-------------cross multiply

(645120×10)÷60 =107520 milliliters

But you know

1 milliliter=0.001 liters

107520 milliliters=?-----------cross multiply

107520×0.001

=107.52 liters

=108 liters
