Answer:
x = - 1
Step-by-step explanation:
- 5x - 16 = 9x + x - 1
- 5x - 16 + 16 = 9x + x - 1 + 16
- 5x = 9x + x - 1 + 16
- 5x = 10x + 15
- 5x - 10x = 10x - 10x + 15
- 15x = 10x - 10x + 15
- 15x = 15
- 15x ÷ - 15 = 15 ÷ - 15
x = 15 ÷ - 15
x = - 1
Answer:
32
Step-by-step explanation:
The formula needed to solve this question by hand is:
![x^{\frac{m}{n}} =\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D)
256^(5/8) = 8th root of 256^5
256^(5/8) = 8th root of 1280
<u>256^(5/8) = 32</u>
For the second one, remember LW=are for fiding the area of the base,
for cone, base=circle, so therfor V=HB/3, and B=circle=pir^2, so V=(1/3)(hpir^2)
h=17
r=6
V=(1/3)(17(3.14)6^2)
V=17(3.14)12
V=640.56
rond tenth
V=640.6
B
Answer:
if they all have the same angle they r congruent
Step-by-step explanation:
Answer:
480 Litres
Step-by-step explanation:
Percentage increase = 20% × 400
New value =
400 + Percentage increase =
400 + (20% × 400) =
400 + 20% × 400 =
(1 + 20%) × 400 =
(100% + 20%) × 400 =
120% × 400 =
120 ÷ 100 × 400 =
120 × 400 ÷ 100 =
48,000 ÷ 100 =
480
