Answer:
Z = 20
Step-by-step explanation:
3 x 20 = 60
60 - 12 = 48
Using the Pythagorean theorem:
a^2 + 24^2 = 26^2
a^2 + 576 = 676
a^2 = 676 - 576
a^2 = 100
a = SQRT(100)
a = 10
Answer:
18
Step-by-step explanation:
w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:
w = kz
When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:
12 = 4k
Dividing both sides by 4:
12/4 = 4k/4
k = 3
Therefore the equation becomes:
w = 3z
The value of w when z = 6 is given as:
w = 3(6)
w = 18
Answer:
1584/7 in² ≈ 226.3 in²
Step-by-step explanation:
Given,
- Radius R = 3 in
- Height H = 8 in
- Volume V = ?
We know that,
Volume(Cylinder) = πr²h
Substitute values,
Taking π as 22/7
- 72*22/7
- 1584/7 ≈ 226.3 in²
Answer:
y+2 = 3/4 (x-1)
Step-by-step explanation:
We have a slope and a point, we can use the point slope form of the equation for a line
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is the point
y--2 = 3/4(x-1)
y+2 = 3/4 (x-1)
