It is a right triangle, so we can use pythagorean theorem which states
a^2 + b^2 = c^2
Leg^2 + Leg^2 = Hypotenuse^2
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 144
x=12
We know that
[area of a circle]=pi*r²
diameter=10 units
r=diameter/2------> r=10/2----> r=5 units
[area of a circle]=pi*5²------> 25*pi units²------> 78.5 unit²
the answer is
≈78.54 units²
and
<span> 25π units</span>²
Answer:
it would be 90 because it has o be a 5 to 9 to round up but is a 1so you can round up
Step-by-step explanation:
Answer:
d = 17.58
Step-by-step explanation:
d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2
P1(0, 0, 0) P2(8, 7, 14)
Substitute the values in the above equation and you will get
d = √(8 - 0)^2 + (7 - 0)^2 + (14 - 0)^2
= √(64 + 49 + 196)
= √309
= 17.58
Answer:
A= .75 B= .75
Step-by-step explanation:
Plug in .75. 5(.75) + 3(.75) = 6
7(.75) + 9(.75) = 12
You would turn a to x and b to y to get ---> 5x + 3y = 6 and 7x + 9y = 12 -----> then you would multiply the first equation ^^^^^ by 3 to cancel to give you 15x + 9y = 18 (I did that to get 9y and cancel out the 9y in the other equation) next do 15x + 9y = 18 - 7x + 9y = 12 to get ----> 8x = 6 ---> divide by 8 to get ---> x = .75
Hope this helped!!
