Answer:
Judy = $5/hr
Ben = $4/hr
Step-by-step explanation:
Judy's hours at work - x
Ben's hours at work - y
8x + 10y = 80
9x + 5y = 65
Given these two equations above, we get:
10y = 80 - 8x, which means y = 8 - 0.8x.
Substitute y in the second equation with 8 - 0.8x, so we have:
9x + 5 (8 - 0.8x) = 65
9x + 40 - 4x = 65
5x = 25
x = 5
Come back to the first equation, substitute x:
8*5 + 10y = 80
10y = 80 - 40
y = 4
He should use the Pythagorean Theorem to find the missing length.
Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.
So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5
Therefore, the radius of circle L is 5 feet.
Answer:
44
Step-by-step explanation:
to find circumference of a circle you need to multiple r (7 in here) with 2 and pi
therefore the answer is : 2x7x3 = 42 or 44 approximately
if you mean.
then the answer would be,

Step-by-step explanation:
How do you factor trinomials? -
You factor trinomials by using methods like FOIL multiplication and simple factoring patterns.
How can we check the binomial factors to verify that they are truly factors?
We can multiply the binomial factors out to see that they are truly factors.
Create an example of a trinomial and factor it to its binomial factors.
+5x+6 factors into
(x+2)(x+3).
Sorry for the trashy answer.
