Answer:
we need the actual problem
Step-by-step explanation:
please post a photo or just type out the question
First you need to divide 125 / 25 which is 5 then you do subtraction 21 x 5 which is 105, then you subtract again 125 - 105 which is 20, 20 light bulbs will be broken. Or you could have just multiplied 5 by 4 which is the amount of light bulbs that were broken which is a lot easier...
Answer:
i think thats right
Step-by-step explanation:
Answer:
The volume of the ball is 256 cm³
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for V
The volume is equal to the ratio of the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
1. Multiply the hourly rate by the number of hours worked ( 22.5h) add that to the flat fee ( 22.5h +35) and that needs to be equal to or greater than what he expects to make:
A. 22.5h + 35 ≥ 215 , with a solution of h ≥ 8
2. Same method as number 1:
C. $3 + 1.80m ≤ $25
3. Each fraction would need 1 negative sign and have the same numerator and denominator, so the answer would be B.6/-7
