Answer:
Michael needs to purchase 1 5/8 feet more of metal flashing.
Step-by-step explanation:
To have the same denominator in both fractions, you can multiply 4 by 2. This will turn out to be 8, resulting in 8 being our common denominator. To achieve this, multiply:
<u>7</u> x <u>2</u> = <u>14</u> or 1 6/8
4 2 8
We next add both fractions together, resulting in:
3 1/8 + 1 6/8 = 4 7/8
The fraction 6 1/2 can also be expressed as 6 4/8, so to find out how much metal Michael still needs to purchase, subtract 4 7/8 from 6 4/8.
Answer:
1. D- All of the above
2. B- The material the acid is poured on
3. C- Mass of the ball
4. A- Temperature
Step-by-step explanation:
2. The control variable is what stays the same so the material the acid is poured on must be the same as different materials have different reactions to acids.
3. The independent variable is what's being changed and in this experiment the mass of the ball is changed each time
4. The independent variable is what's being changed and in this experiment the temperature is different in each cup.
Hope this helped! :)
Answer: f(x)=|2x+1|+5
f(-3) = |2*-3 + 1|+5
= |-6 + 1|+5
= |-5|+5 = 5 + 5 = 10
f(-3) = 10
