Hello! We know that we have $400. So 23 ten dollar bills is equal to $230. How? We multiply 23 x 10 and get $230. Then, we have 46 dimes. A dime is worth 10 cents so we multiply 46 x 10 which equals $4.60. And of course we have the 19 cents. Now we add. 400 + 230 + 4.60 + 19 = $653.6.
Hope this Helps!
Answer:
Is an equivalent part of a proper fraction, expressed in split parts with denominators whose LCM is the denominator of the fraction.
Question:
A fastball is hit straight up over home plate. The ball's height, h (in feet), from the ground is modeled by h(t)=-16t^2+80t+5, where t is measured in seconds. Write an equation to determine how long it will take for the ball to reach the ground.
Answer:
Step-by-step explanation:
Given
Required
Find t when the ball hits the ground
This implies that h(t) = 0
So, we have:
Reorder
Using quadratic formula, we have:
Where
So, we have:
This gives:
or
or
or
But time can not be negative.
So, we have:
<em>Hence, time to hit the ground is 5.0625 seconds</em>
First, find the surface area of the bigger sides (there are 4 of them so what you get for one you will multiply by 4)
12 x 8 = 96
96 x 4 = 384
Then find the surface area of the smaller sides ( there are two small sides so multiply your answer by two)
8 x 8 = 64
64 x 2 =128
Then add both together
128 +384 = 512

Answer:
48 dollars
Step-by-step explanation:
grant originally had 36 and john had 12
decrease grant by 9 and increase john by 9
grant has 27, and john has 21
difference is 6 so the sum is 48.
