Remark
If you really take this question seriously, you will stop tailgating immediately. Being any less than 6 car lengths away from the car in front of you is dangerous even if you are paying attention, never mind if you are not.
Conversion
Now just multiply all the numerators together
60 * 6280 * 1 = 316800
And then multiply all the denominators together
1 * 1 * 3600 = 3600
Divide the numerators / denominators to get 316800/3600 = 88 feet / second
If you go 88 feet in 1 second you will go 88 * 4 feet in 4 seconds which is 352 which is about the length of a football field. It is an awfully long way to be inattentive.
So, if 60 beats was decreased by 2/5 before, we know that 60 beats = 3/5 of her heart rate after she ran the mile.
(Because 1 - 2/5 = 3/5)
So, 3/5 = 60, and we're trying to find 1.
So I would first divide both sides by 3.
3/5 = 60
/3 /3
1/5 = 20
Then multiply both sides by 5.
1/5 * 5 = 20 * 5
1 = 100
So her heart rate was 100 beats per minute immediately after she ran the mile.
Answer:
it's answer is 33°
Step-by-step explanation:
116° + 31° + m<1 = 180° [being sum of angles of triangle ]
147° + m< 1 = 180°
m<1 = 180° - 147°
m<1 = 33°
Common factors of 50: 1, 2, 5, 10, 25, 50
Common factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Common factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100
You're welcome.
Here you are giving only the amount they want to raise (namely profit times number of magazines sold), and here you are also giving Money they want to raise... So clarifying, the money they want to raise, should include the money they will spend on buying the magazines (there is no statement saying they found them, or were given the magazines, so a cost should be involved)
Now if they are only making the count of "Field trip costs X amount of money, and given we have to make a profit of $5.5, How many must we sell?" then the equation should be n=X/5.5
Should the story be, how much money must they raise to have a profit of 5.5 on each magazine and still have enough for the field trip, then you have a different equation which varies only in adding the cost of each magazine, either case, M should be defined not as money they need to raise (cause here they will be short on their goal) but Money they must earn. And again, you should rewrite your equation to be:
M=Amount they must raise
C=Cost per magazine
n=Number of magazines
p=profit $5.5 per magazine
C+p=M/n
And rewriting the previous they should make:
n(C+p)=M -----> n(C+5.5)=M <span>m/n = 5.50 </span>
<span>m/n x n = 5.50 x n //// multiply each side by n </span>
<span>m = 5.5n</span>
