1. 30 MPH
(divide hours (4.5) from miles (120))
2. $55.80
(divide fencing per cost (8) from cost (12.40) to get how much it costs per foot (1.55) then multiply it by how much feet you need (36))
Answer:
She made $21.69 in tips.
Step-by-step explanation:
Take the wage per hour and multiply by the number of hours worked. 11.25x12.25 = 137.81
Then we subtract that number by her final pay. 159.50-137.81= $21.69 in tips
Answer:
5.5 inches
Step-by-step explanation:
Since it is a hexagon, there is 6 faces. The total lateral area is 6 times area of one face. The area of one face is 12 times the width so the total is 6*12*width which equals 396. Dividing both sides by 6 gives you 12*width = 66. Dividing both sides by 12 gives you width = 5.5.
1/2 - 3/8 = 4/8 - 3/8 = 1/8
you have to find a common denominator before you can subtract. in this case it is 8
Answer:
Percent:
There are many formulas for percentage problems. You can think of the most basic as X/Y = P x 100. The formulas below are all mathematical variations of this formula.
X and Y are numbers and P is the percentage:
Find P percent of X
Find what percent of X is Y
Find X if P percent of it is Y
Mixture:
Solving a percent mixture problem can be done using the equation Ar = Q, where A is the amount of a solution, r is the percent concentration of a substance in the solution, and Q is the quantity of the substance in the solution.
Proportion:
Many "proportion" word problems can be solved using other methods, so they may be familiar to you. For instance, if you've learned about straight-line equations, then you've learned about the slope of a straight line, and how this slope is sometimes referred to as being "rise over run". But that word "over" gives a hint that, yes, we're talking about a fraction. And this means that "rise over run" can be discussed within the context of proportions.
