Answer:
The answer is 4.5 and 9/2
Step-by-step explanation:
First
54 / 12 = 4.5
Then
Change it into a fraction
Write is fraction form 4.5 / 1
Multiply both numerator and denominator by 10 for every number after the decimal point
4.5 × 10
1 × 10
Which will equal 45/10
Then Reduce the fraction gives 9/2
Answer:
20
Step-by-step explanation:
The first step is to find out the similarity reason of the sides of the triangle, so we just divide the big side by the small side (12/4=3).
Now, for the similarity reason of the areas, we just square that number (3^2=9).
Then we just divide the area of the big triangle by 9, which is 180/9= 20.
Answer:
11 boys walk to school each day
Step-by-step explanation:
<em>*The following will be assumed: the only genders of students in the class are male or female; the only options for getting to school are walking or not walking</em>
If there are 32 students in the class total, and there are 15 boys,
32 - 15 = 17
there are 17 girls.
If 8 of these girls do not walk to school,
17 - 8 = 9
9 girls walk to school
So, if 20 total students walk to school, and 9 of those are girls
20 - 9 = 11
11 boys walk to school each day.
6% means 6/100 or 0.06
"of" means "times"
0.06 x 300 = 18
You can use the formula 2(a+b
This will get you 161.5 ft
