Answer:
He is incorrect. He would need 225g of cocoa powder
Step-by-step explanation:
1. Lets calculate how much powder do we need per one cupcake, so 60 divided by 20, since 60g makes 20 cupcakes, 60/20 = we get 3g of cocoa powder per one cupcake.
2. Now we can multiply that by 75, 75*3=225, and 225g is more than 210g
The answer is a = 2.25.
Simplifying
7 + -4(3a + -5) = 0
Reorder the terms:
7 + -4(-5 + 3a) = 0
7 + (-5 * -4 + 3a * -4) = 0
7 + (20 + -12a) = 0
Combine like terms: 7 + 20 = 27
27 + -12a = 0
Solving
27 + -12a = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-27' to each side of the equation.
27 + -27 + -12a = 0 + -27
Combine like terms: 27 + -27 = 0
0 + -12a = 0 + -27
-12a = 0 + -27
Combine like terms: 0 + -27 = -27
-12a = -27
Divide each side by '-12'.
a = 2.25
Simplifying
a = 2.25
Answer:
It would be 8 PM.
Step-by-step explanation:
If you keep decreasing 23 by 7 till you get to -5, it would have to be decreased 4 times to get to -5. This means that the time would have to go up 4 times the 45 minute rate, which would be 3 hours. 5 pm + 3 hours is 8 PM.
Answer:
They are similar because Since all the sides are equal in each triangle, the ratio of corresponding sides will all be equal
