P.s it is not 60

Answers

Answer 1

Answer:

$30

Step-by-step explanation:

3/3 - 1/3 = 2/3

The fraction shows how much she has left.

2/3 = $20

1/3 = $20 ÷ 2 = $10

solve for x in triangle

Answers

X=60degrees

bc you find 180-125 bc it is a straight angle. You get 55 degrees. Then you add 65+55=120. 180-120=60 degrees. This is because every triangle must have a sum of angles that equals 180 degrees.

Answer:

x = 23.6

Step-by-step explanation:

Since all the edge angles are 90, if the upper part angle is 35, the lower one in ADC is 90-35 = 65

we now proceed to use the tangent ratio

The tangent ratio is opposite/adjacent

Thus;

Tan 65 = x/11

x = 11 tan 65

x = 23.6

Combine Like Terms :2y+7z-2z+4y+8+y+2

Answers

Answer:

7y + 5z + 10

Step-by-step explanation:

2y + 7z - 2z + 4y + 8 + y + 2

Like terms are terms that have the same variable part.

2y, 4y, y are like terms (remember that y is the same as 1y when you add)

7z, -2z are like terms

8, 2 are like terms

2y + 7z - 2z + 4y + 8 + y + 2 =

= 2y + 4y + y + 7z - 2z + 8 + 2

= 7y + 5z + 10

Answers

Answer:

It would be the first one.

Step-by-step explanation:

When it says "at least" that means Kristen has to walk 20 miles at minimum, but she can walk more if she chooses to. Therefore in context of the problem, the greater than or equal to sign would work best.

Redfield, New York is one of the snowiest places in the United States, with an annual average snowfall of 22 feet. So far this year Redfield has received 105.6 inches of snow. What percentage of its average annual snowfall has fallen in Redfield so far?

Answers

Answer: 40 Percent

Step-by-step explanation:

105.6 Inches / 12 inches per feet = 8.8 Feet

8.8/22 annual = .4

.4 x 100 = 40 Percent

The percentage of its average annual snowfall has fallen in Redfield so far is 40 percent.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Redfield receives an annual average snowfall of 22 feet.

We know that, 1 foot = 12 inches

Now, 22 feet = 22×12

= 264

This year Redfield has received 105.6 inches of snow.

Here, percentage = 105.6/264 ×100

= 0.4×100

= 40%

Therefore, so far Redfield has received 40% of snowfall.
