Answer:
the answer is C
Step-by-step explanation:
it it can be calculated by using simple quadratic formula
B. adding 40 to both sides of the equation
x^2 - 40 = 0
x^2 = 40
x = ± √40
Answer:
Distance traveled 17.5 kilometers
Step-by-step explanation:
We can use the following equation to find the distance traveled,
Distance traveled = Speed * Time
First we need to find the total time he walked = 2.30 p.m. - 11.a.m.
=
hours
Now we can substitute the values to the equation,
Distance traveled =
kilometers per hour *
hours
=
kilometers
= 17.5 kilometers
Answer:
8 inches
Step-by-step explanation:
Nacho cheese
v= Pi×radius×2×height
v = 3.14×8×2×4 = 200.96
jalapeño
3.14×4×2=25.12
200.96÷25.12=8
the height is 8
to check your work you can do
(multiply by 8 and see if it equals 200.96)
3.14×4×2×8 = 200.96
since the volume is the same as the volume for nacho cheese we can say that 8 inches for height is correct
X = -1. 8 = 4x+12
-4 = 4x
-1 = x
