The answers are A and F.
You can tell by looking at the slopes and seeing that they've been flipped and one is positive while the other is negative.
X+7.5=21.5
Subtract 7.5 from both sides
X=14 which is C
hope this helps good luck have a nice day
Answer:
4
Step-by-step explanation:
the formula for radius is

so. 500 divided by pi times 10. then square root your final answer. cool. let's get started.
3.14*10 is 31.4, you can do that without thinking.
500/31.4=15.92
15.92= 3.99, or just 4
the radius is four.
Answer:
The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles
Step-by-step explanation:
We are given
Bethel Park is 28 miles directly west of Jeanette
10.3 miles directly south of Pittsburgh
We can draw diagram
we can see that this is triangle
so, we can use Pythagoras theorem
and we get

now, we can solve for x


So,
The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles

=


=

let AB = E
⇒ (AB) (7 m) = (1.75 m) ( BC + AB)
(AB) (7 m) = (1.75 m) (1.5 m + AB)
= 2.625 m² + (1.75 m ) (AB)
(AB) (7 m - 1.75 m) = 2.625 m²
∴ AB = 2.625 m² ÷ (5.25 m)
<span>
⇒ the length of AB is 0.5 m</span>
