Answer: 52.5 yards
Explanation:
Perimeter = 16.25 + 16.25 + 10 + 10 = 52.5 yards
Answer:
<h2><u><em>
Letter A</em></u></h2>
Step-by-step explanation:
First of all, we have to solve all the equations
First one is (4*1)-6
<em>We have to use PEMDAS</em>
<em>which stands for </em>
<em>Parenthesis</em>
<em>Exponents</em>
<em>Multiplication</em>
<em>Divison</em>
<em>Addition</em>
<em>Subtraction</em>
In (4*1)-6
You have to do 4*1 first ~ which equals 4
the next step would be 4-6 ~ which equals -2
The next equation would be (1*4)-6
First do 1*4 ~ which is 4
Next 4-6 ~ which again equals -2
Next equation is (1*6)-(4-6)
Parenthesis first, 1*6=6
4-6=-2
6-(-2)
which equals 8
Our next equation is 6-(1*4)
1*4=4
6-4~ which equals 2
Our last equation is 4*(1-6)
Parenthesis comes first, so it would be 1-6 first
which equals -5
4*(-5) would be our final step ~ which equals -20
All of our answers would be
-2 - from the top equation
-2 - from letter A
8 - from letter B
2 - from letter C
-20 - from letter D
which means <u><em>Letter A</em></u> is the answer.
Hope this is helpful.
Answer:
<em>There are 12 boys and 18 girls</em>
Step-by-step explanation:
<u>Equations</u>
There are 30 students in a class. Let's call:
x = number of boys
Since the sum of boys and girls is 30:
30 - x = number of girls
The ratio of boys to girls is 2:3, thus:
Crossing denominators:
3x = 2(30 - x)
Operating the parentheses:
3x = 60 - 2x
Adding 2x:
5x = 60
Dividing by 5:
x = 60/5 = 12
x = 12
There are 12 boys and 30-12=18 girls
Answer:
1) 6
2)4
3)27
4)126
5)15
Step-by-step explanation:
1. We need to see how many 8-miles are in 24 miles, than multiple it with 2in.
(24/8)*2=3*2=6in
2. Fist we calcue how many 17-feets are in 68feets, and multiple that with 1in.
(68/17)*1=4
3. We first see how many 3ins are in 9ins, and than multiple that with 9feet
(9/3)*9=3*9=27
4. First see how many 2ins are in 36ins, and then multiple it with 7.
(36/2)*7=18*7=126feet
5. See how many 15fts are in 75ft And than multiple it with 3.
(75/15)*3=5*3=15
The angular velocity is the linear speed divided by the radius.
ω = d/(t*r) = (14.13 ft)/((3 s)*(6 ft))
ω = 0.785 radians/second
There are 180/π degrees per radian, so the angular velocity can also be written as ...
ω = 45 degrees/second
