Answer:
B.70
Step-by-step explanation:
For one or two angles are complementary angle(s), they have to equal 90°.
So, we need to find the larger angle, but what about the other?
Let x be the other angle and y be the angle we are looking for
x + y = 90
Lets look for x first, since one angle is ten less than four times the angle we are looking for or visa versa, we must:
y = 4x - 10
For an exchange, lets take out the y variable for another x variable:
So now we should have x + 4x - 10 = 90
Combine like terms and do cross equation :
x + 4x -10 = 90
5x - 10 = 90
Add 10 to both sides:
5x = 100
100/5 = 20
So <u><em>x=20</em></u>
<u><em></em></u>
Now for y which is what we are looking for,
y = 4x - 10
Since x is 20, plug it in
y = 80 - 10
y=70 is our larger angle
15 times 2.2 equals 33 and 21 times 2.2 equals 46.2 you would then multiply 33 by 46.2 and you would get 1024.6
Answer:
Mr wentz traveled 40 miles in 40 minutes.
Answer:
Solve the equation so it is in the y=mx+b form.
Step 1. 6x+9y = 216
Step 2. 9y = -6x+216
Step 3. y = -6/9x+24
Step 4. Simplify/Reduce to get y = -2/3x+24
Since it is Parallel then the slope is the same so the slope is -2/3x.
Answer:
25%.
Step-by-step explanation:
First, let's find the area of both circles. The area of a circle is given by:
The radius of the smaller circle is one. Thus, its area is:
The radius of the larger circle is two. Thus, its area is:
The probability that a random point chosen will be inside the small circle will be the area of the small circle over the total area. Hence:
The probability of a random point being in the small circle is 25%.
