There is a method of doing this called unit analysis. It automatically sets up the question in such away that you multiply all the numerators together and divide by all the denominators multiplied together. It is very handy to know.
Notice how the cancellation takes place as you progress from left to right. You are given seconds to start with and that cancels at the end, so that you are only left with meters.
The distance traveled in 10 seconds = 1080000 / 3600 = 300 meters.
Answer: 300 meters
You could also do this question by proportions, which you will no doubt get as your second answer.
Answer:
d. 1134 inches squared
Step-by-step explanation:
The formula for the area of a circle is
where r is the radius.
You are given r=19 here so replace r in with 19 giving us:
Then it is to the calculator we go:
1134 inches squared
Answer:
Marissa should put $31.38 in her savings account.
Step-by-step explanation:
To find the amount of money she put in her savings account, you have to multiply the amount Marissa got in her paycheck last week for 25% that is the percentage of her earnings she would like to put in her savings account:
$125.52*25%=$31.38
According to this, the answer is that Marissa should put $31.38 in her savings account.
We can do several rectangles and 2 triangles
the easiest way is to find the area of the big rectangle minus the cut off pices
a. 1 big rectangle-2 corner triangles
b. area rectangle=lenght times height=24 times 11=264 square feet
the triangles
bottom left one is height 11-7=4 and base 24-14=10
bottom left=1/2 times 4 times 10=20
top right is 24-20 by 11-6 or 4 by 5, area=1/2 times 4 times 5=10
so
rectangle-triangles=264-(20+10)=264-30=234 square feet
Answer:
one is equal
Step-by-step explanation:
this is asking which 2 paired items have the same fractional ratio I believe. So all we have to do is make ratios of price to item amount and see if they are equal.
1. 4.5/3 = 6/5
this one we divide numerator and denominator of left side by 1.5 and get:
3/2 = 6/5
this is not true so wrong
2. 5/2 = 15.25/6
2.5 = 2.5416666
sometimes easier to use calculator then reduce. But not equal so wrong.
3. 4.75/5 = 9/10
95/100 = 9/10
wrong
4. 9/4 = 13.5/ 6
4.5/2 =4.5/2
this one is equal
