<h2> <u><em>
answer: </em></u>21 is 70% of 30
</h2>
<h2><u><em>
Working out percentages
</em></u></h2><h2><u><em>
We have, 70% × x = 21
or, 70100 × x = 21
</em></u></h2><h2><u><em>
Multiplying both sides by 100 and dividing both sides by 70,
</em></u></h2><h2><u><em>
we have x = 21 × 100
70
x = 30

If you are using a calculator, simply enter 21×100÷70, which will give you the answer.</em></u></h2>
Answer:
The following are some inequalities that represent the possible position of the playground.
2x ≥ -2 and x < -3
x + 3 ≤ 1 and –x > -3
x + 4 ≤ 2 and x + 4 > 7
2x – 1 ≥ -5 and 3x < 9
The city council planning for playground, that is more than 5 blocks from fountain and at least 2 blocks from center of park.
A solid dot on negative two points less than -2 and a circle dot on positive three points in the direction indicating greater than 3. So the right inequality is x + 3 ≤ 1 and –x > -3. That represents the possible position of ground.
Hence, the inequality x + 3 ≤ 1 and –x > -3 is the playground's possible position.
Answer:
9
Step-by-step explanation:
cube root the number
The formula of the volume of an oblique cylinder is V =
r²h where
is 3.14, r is the radius of the circular base of the cylinder and h is the height of the cylinder. You are given a slant length and radius of 26 and 10 units. You can get the height by using pythagorean theorem c²=a²+b².
c²=a²+b²
26² = 10² + b²
b = 24
V =
r²h
V =
(10)²(24)
V = 7,540 units³
The height is 24.
We can use Pythagorean’s Theorem: a^2+b^2=c^2
substituting values we get:
a^2+7^2=25^2
Solving we get:
a^2+49=625
a^2=576
a=24.
So the height is 24.
Hope this helps!
