Answer:
C. 16 : 22
Step-by-step explanation:
Given:
- Apple trees = 16
- Orange trees = 22
- Cherry trees = 1
Ratio of apples trees to orange trees:
⇒ apple : orange
⇒ 16 : 22
In rolling a die, there are 6 possible outcomes. Each face is numbered from 1 to 6. The possible combinations of numbers so that their sum is 5 is, 1 - 4, 2 - 3, 3 - 2, 4 - 1. Thus, the answer is that they are four possible outcomes corresponding to the given event.
You just have to multiply 23 * 3 = 69. So there were 23 acres of potatoes and 69 acres of corn and oats. 69 + 23 = 92. Your answer is 92 acres total.
All you need to do to answer this equation is to continually add 3/4 until you get 9 1/2 or as close as you can get without going over. In this case if you keep on adding 3/4 you will get only up to 9 because you cant go over your value of 9 1/2. Your answer is D.
Answer:
The first mechanic $90/hour and the second charged $70/hour
Step-by-step explanation:
Lets start off by letting x be the first mechanics rate and y being the second mechanics rate. We know that the first mechanic worked 5 hours and that the second mechanic worked 10 hours and together they charged 1150. An equation to express this would be:
5x+10y = 1150
We also know that together they charged 160/per hour. An equation to express this would be:
x+y = 160
Now we can solve the second equation for x or the first mechanics rate.
x+y = 160
x = 160 - y
Now that we have an expression for x we can plug that back into the first equation and solve for y or how much the second mechanic charged.
5x+10y=1150 plug in x =160-y
5(160-y)+10y=1150 Distribute
800 -5y+10y = 1150 Combine like terms
800 +5y = 1150 Subtract 800 from both sides
5y = 350 divide by 5
y = 70
So we know that the second mechanic charged $70/hour. We also know that(from our work before) that the first mechanic charges $160 - the rate the second mechanic charged. We know that's $70/hour so we can plug in and solve for the first rate.
x = 160-y
x = 160-70
x = 90
So we know that the first mechanic charged $90/hour and the second mechanic charged $70/hour.
