Answer:
3.75
Step-by-step explanation:
Set up the following ratio:
2400 watt-hours 1 day
------------------------- = ----------
9000 watt-hours x days
Then do criss-cross-apple-sauce:
x*2400=9000*1
And then solve for x:
2400x=9000
x=9000/2400
x=3.75
Answer:
Step-by-step explanation:
Given the inequality
0.21x + 0.05(17 - x) > 2.55 where x is the amount of 21% lotion needed
Given
0.21x + 0.05(17 - x) > 2.55
Open the parenthesis
0.21x + 0.85-0.05x > 2.55
Collect like terms
0.21x-0.05x+0.85>2.55
0.16x+0.85>2.55
0.16x>2.55-0.85
0.16x > 1.7
x > 1.7/0.16
x > 10.625
Hence she will need 21% lotion approximately greater than 10 ounces
Answer:
35, 55, and 90 degrees
Step-by-step explanation:
The acute angles of a right triangle are complementary, so if the smallest angle measures x, the next largest angle measures (x+20) degrees. So, x+(x+20)=90, meaning x=35.
So, the angles measure 35, 55, and 90 degrees.
