Answer:
? = 7.2
Step-by-step explanation:
Remark
Is that a misshapen circle or is it an ellipse? I'm going to assume it is a circle, but if I am wrong, leave a comment. A tangent will meet a diameter's end at right angles which allows you to use the Pythagorean theorem.
Formula
a^2 + b^2 = c^2
Givens
c = 12
a = 9.6
b = ?
Solution
c^2 - a^2 = b^2
144 - 92.16 = b^2
b^2 = 51.84 Take the square root of both sides
sqrt(b^2) = sqrt(51.84)
b = 7.2
Answer:
x = -1, y = 1
Step-by-step explanation:
2x-y=-3 // y = 2x + 3 (eqn 1)
3x+y=-2 (eqn 2)
sub 1 into 2
3x + 2x + 3 = -2
5x = -5
x = -1
sub x = -1 into eqn 1
y = -2+3
y = 1
Answer:
Answer is 12.
Step-by-step explanation:
Answer:
Let "b" be the distance that Brian biked.
Thus, the expression is b-12.
Let me know if this helps!
Answer:
Step-by-step explanation:
2/5, 3/5, and 4/5
= 2/5 × 3/5 × 4/5
= (2×3×4)/(5×5×5)
= 24/125
