Answer:
depends upon the degree of the angle
Step-by-step explanation:
vertically opposite angles are always equal like
80 = 80 sum is equal to 160 degrees not equal to 90
45 = 45 , sums equal to 90 degrees ,equal to 90
30 = 30 sum is equal to 60 degrees, not equal to 90
so we can say it depends what is the no of degrees if it is 45 only we can say the vertically opposite angles are complementary angle
Answer: 250 yd
Step-by-step explanation:
From the question, we are informed that the scale model of the statue of liberty is 8 inches tall and that the scale used is 1 in = 30yd.
Since the scale used was 1 in = 30 yd, the actual height of the statue of liberty will be:
= 8 × 30
= 240 yd
Answer:
[6, infinity)
Step-by-step explanation:
Answer:
It would take them 6.667 minutes to paint 50 square feet together.
Step-by-step explanation:
This is a classic work problem. If Sam can do the job in 10 minutes, she can get done 1/10 of the job in one minute. If you can do the job in 5 minutes, you can 1/5 of the job done in one minute. To find out how many minutes it will take them together to paint 25 square feet, set the addition of their times equal to 1/x:
x is how long it takes them to get the job done together. Find the common denominator and multiply it through be everything to get rid of the denominators altogether. That denominator is 10x:
Simplify to get the simple equation x + 2x = 10 and 3x = 10. That means that x=3 1/3. That's how long it takes to do 25 square feet. Double that time for 50 square feet.
<h3><u>The first number, x, is equal to 955.</u></h3><h3><u>The second number, y, is equal to 191.</u></h3>
x = 5y
x - y = 764
Because we have a value for x, we can plug it into the second equation to solve for y.
5y - y = 764
Combine like terms.
4y = 764
Divide both sides by 4.
y = 191
Because we have a value for y, we can solve for x.
x = 5(191)
x = 955
