Applying the Pythagorean theorem, solve this triangle.
Answer:
The length of the hypotenuse is the square root of 169, which in turn is 13.
Step-by-step explanation:
Here we have a right triangle with leg lengths 12 m and 5 m. Because this is a right triangle, we can apply the Pythagorean Theorem to find the length of the hypotenuse.
The Theorem states that a^2 + b^2 = c^2. In this particular case,
(12 m)^2 + (5 m)^2 = c^2
which in turn becomes:
144 + 25 = 169. The length of the hypotenuse is the square root of 169, which in turn is 13.
A group of twelve friends went bowling. The regular price was $8.00. The bowling alley offered a discount price of $6.00 to college students. Is they paid a total of $80.00, how many paid the regular price and how many got the discount?
Answer:
x = friends that paid discount price = 8
y = friends that paid regular price = 4
Step-by-step explanation:
Let
x = friends that paid discount price
y = friends that paid regular price
x + y = 12 (1)
6x + 8y = 80 (2)
From (1)
x = 12 - y
Substitute x = 12 - y into (2)
6x + 8y = 80 (2)
6(12 - y) + 8y = 80
72 - 6y + 8y = 80
- 6y + 8y = 80 - 72
2y = 8
y = 8/2
y = 4
Substitute y = 4 into (1)
x + y = 12 (1)
x + 4 = 12
x = 12 - 4
x = 8
x = friends that paid discount price = 8
y = friends that paid regular price = 4

Expand to write an equivalent expression. −5(7m−2)
Answer:
Step-by-step explanation:
-5(7m-2)
-5*7m-(-5)*-2
-35m+10
The expansion of an equivalent expression −5(7m−2) is -35m + 10.
What is a distributive property?Distributive property says that the sum of two or more addends multiplied by a number, gives the same answer as distributing the multiplier, multiplying each added separately, and adding the products together.
Given expression
−5(7m−2)
For expanding the expression, use distributive property
= -5 × 7m - (-5) × (-2)
= -35m + 5 × 2
= -35m + 10
Hence, The expansion of an equivalent expression −5(7m−2) is -35m + 10.

Part A The measure of ∠AFC is 120°, and the measure of ∠BFC is 95°. Which equation can you use to find the measure of ∠AFB? 120° + 95° = x 120° – 95° = x 120° + x = 95° x – 120° = 95°
Answer:
x = 120-95
Step-by-step explanation:
The correct equation for the expression is:
∠AFC = ∠AFB+ ∠BFC
Given that
∠AFC = 120°
∠BFC = 95°
Substitute
120= ∠AFB+95
∠AFB = 120-95
If ∠AFB = x
The required equation will be:
x = 120-95

Answer:
(-3, -4)
Step-by-step explanation:
Handy fact: the average of two numbers is exactly halfway between them.
To find the midpoint, average the x-coordinates; average the y-coordinates.
(1 + -7)/2 = -6/2 = -3
(-8 + 0)/2 = -8/2 = -4
The midpoint is (-3, -4).
Ali earns $80 in 10 hours. How long would it take him to earn $200?
Answer:
25 hours
Step-by-step explanation:
first you ask yourself that :
if it takes just 10 hrs to make $80 , would it take more or less hours to make $200.
The answer is it will take more hours to make $200,
Based on this idea established: we say if it's giving more then less would divide.
so therefore:
we have
[tex] \frac{200}{80} \times 10 [/tex]
finally we have 25 hours.
