Answer:

x=16[tex]\sqrt{\\2\\}[/tex]

y= 16

Step-by-step explanation:

Since we know that this is a right triangle, all sides must add up to 180°.  This means that our unknown angle is 45°.  With two 45° angles, we know that side y must be 16 (the same as the other corresponding angle).  Once we know both legs, we can use Pythagorean Theorem to determine that the hypotenuse, or side x is =16[tex]\sqrt{2}[/tex]

Answer = 20%

2) 10/100 as a percentage:
(This is already over 100 so the answer would just be 10%)

3) 1/100 as a percentage:
(Again, this is already over 100 so the answer would just be 1%)

4) 2/5 as a percentage:
2/5 x 100 = 40
Answer = 40%

5) 3/5 as a percentage
3/5 x 100 = 60
Answer = 60%

6) 4/5 as a percentage
4/5 x 100 = 80
Answer = 80%

7) 1/2 as a percentage
1/2 x 100 = 50
Answer = 50%

8) 5/100 as a percentage

Answer:

32.85°

Step-by-step explanation:

Used a fancy calculator & just took a test like this

good luck, i hope this helps :)

Answer:

x = 32.8599

Step-by-step explanation:

you have the hypotenuse and the side adjacent to the angle, so you use

Cos(x) = adjacent/hypotenuse

so

Cos(x) = 21/25

x = cos^-1(21/25)

put this in a calculator:

x = 32.8599 (rounded)

Jennifer has one more nickel than she has dimes. If she has $1.25 how many of each type of coin does she have? (HELP IS APPRECIATED)

Answers

Answer:

She has 9 nickels, and 8 dimes.

Step-by-step explanation:

We know that she has a total of $1.25. We know that a nickel is $0.05, and that a dime is $0.10.

9x$0.05=$0.45

8x$0.10=$0.80

Answer:

9 nickels

8 dimes

Step-by-step explanation:

.05(n + 1) + .10n = 1.25

.05n + .05 + .10n = 1.25

.15n = 1.20

n = 1.2 / .15

n = 8

but there are 9 nickels because there is "one more nickel than dimes"

The amount Lin’s sister earns at her part-time job is proportional to the number of hours she works. She earns $9.60 per hour. Express fractions in the form a/b if necessary.


a. Complete the equation in the form y=kx to describe this situation, where x represents the hours she works and y represents the dollars she earns.



y =
x



b. Is y a function of x? Type yes or no.




c. Complete the equation describing x as a function of y.

Answers

y is a function of x, because for each input x there is only one output y. (It doesn't work backwards. x is not a function of y. not sure if you needed that but there it is!)

The equation would be

y=9.60x

where y is the amount Lin's sister earns and x is the amount of hours she works
