Answer:
77.5
Step-by-step explanation:
For 0.30 for the first 50, just subtract 50 from 175, that leaves 125.
(An easy way to do this is think of quarters, 25+25=50 and 50+25=75 so all you have to do is subtract two 25s and you know it's 125)
Put the 125 to the side, and multiply 50 to 0.30, you get 15.
Then for 0.50 over 50 containers, multiply the remaining 125 with 0.50, you get 62.5.
Add 62.5 and 15 together, that gives you 77.5
Answer:
72 dollars
Step-by-step explanation:
We can write this as a ratio
28 kg 36 kg
------------ = ---------------
56 dollars x dollars
Using cross products
28x = 56*36
Divide each side by 28
28x/28 = 56*36/28
x =72
Answer:
huh
Step-by-step explanation:
Answer:
The graph of y = 2x+1 will never go through the point (2,3) because the graph is a linear function which means it goes in a straight line. Knowing this, when y = 3, x = 5 this means that the function will never hit (2,3)
The radius of the circle and the tangent to the circle form a right angle so we have a right triangle.
Since our triangle is right we can apply the Pythagorean Theorem to find x.
8^2. =6^2 + x^2
X^2= 64-36
x= sqrt 28= 2 sqrt 7 ~ 5.30
