Guy is pouring a new patio for his house. He rents a concrete mixer for $50 per day plus $12.50 per hour. If he is charged $143.75, how long did guy have the concrete mixer?

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

50 + 12.50h = 143.75....where h = # of hrs

12.50h = 143.75 - 50

12.50h = 93.75

h = 93.75 / 12.50

h = 7.5 (or 7 1/2) hrs <====

What is 75 degrees Fahrenheit in the Celsius and kelvin scale?

Answers

To convert Fahrenheit to Celsius, remember this equation.
Subtract 32, multiply 5, divide 9.

Or vice versa,
Multiply 9, divide 5, add 32.

So, 75°F to celsius.
75 - 32 x 5 / 9 = 

Ignore PEMDAS for this.

75 - 32 = 43
43 x 5 = 215
215 / 9 ≈ 23.8


To convert to Kelvin, basically do all the steps all over again, but with one more Subtract 32, multiply 5, divide 9, add 273.15.

So, 75 - 32 x 5 / 9 + 213.15

We already know we get 23.8 from the first three steps, so just add 273.15

23.80 + 273.15 ≈ 296.95

A rectangle has an area of 30 square units and a perimeter of 34 meters.what are the dimensions of this rectangle

Answers

P=2L+2W
A=WL

Therefore, if P=34, and A=30, then let us find the factors of 30 that could give a sum of half of the perimeter which is 34. Therefore:

P=2*15+2*2
A=15*2

P=34
A=30

Therefore, the dimensions of this rectangle are 15 and 2.
