Answer:2
Step-by-step explanation:
2r + 2r + 5 + r + 4r - 3 = 38
9r + 5 - 3 = 38
9r + 2 = 38
9r = 38 - 2
9r = 36
9r/9 = 36/9
r = 4cm
Done!
Notice that the plane figures above are congruent with each other, so that
<h3>#6</h3>
x/8 = 4/16
16x = 8 × 4
16x = 32
x = 2
<h3>#7</h3>
x/5 = 48/6
6x = 5 × 48
6x = 240
x = 40
<h3>#8</h3>
x/7 = 90/10
10x = 7 × 90
10x = 630
x = 63
<h3>#9</h3>
3/x = 10/40
10x = 3 × 40
10x = 120
x = 12
Answer: sqrt 3V/pih = r
Step-by-step explanation:
3V = (pi r^2h)3
3V = pi r^2 h
3V/pih = r^2
Sqrt (3V/pi h) = r
First to answer
Answer:
The answer is True:
Let's solve your equation step-by-step.
1/n−1 = 4/15
Step 1: Cross-multiply.
1/n−1 = 41/ 5
(1)*(15)=4*(n−1)
15=4n−4
Step 2: Flip the equation.
4n−4=15
Step 3: Add 4 to both sides.
4n−4+4=15+4
4n=19
Step 4: Divide both sides by 4.
4n/4=19/4
n=19/4
simplify:
19/4 = 4.75
4.75 in decimal for is equal to 4 3/4
