Noah says to find 20% of a number he divides the number by 5. Is this true explain your answer

Nutka1998 [239]

Answer:

yes

Step-by-step explanation:

note that 20% = $\frac{20}{100}$ = $\frac{1}{5}$

Hence to find 20% of a number, dividing the number by 5 is correct

20% of £30 = $\frac{30}{5}$ = £6

32x - 4 = 4x2 + 60 For the equation shown, choose the description of the solutions.

Furkat [3]

All to one side:

4x^2-32x+64 = 0,

divide by 4:

x^2 -8x + 16 = 0

apply formula or see that it is (x-4)^2!, so only x =4 is a root and it is double.

If M is the midpoint of segment CD with CM = 3x + 1 and MD = 8x - 24, find CD.

ra1l [238]

X = 5 so that would mean if you plug it into both equations, segment CD would be 32 units long.

The length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81 degrees. What is the ap

GuDViN [60]

Answer:

A. 5.19 units

Step-by-step explanation:

$\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle)}$

Given:

$\theta$ = 81°
Arc length = 7.34 units

Substituting given values into the equation and solving for r:

$\implies 7.34=2 \pi r\left(\dfrac{81^{\circ}}{360^{\circ}}\right)$

$\implies 7.34=r\left(\dfrac{18 \pi}{40}\right)$

$\implies 7.34 \cdot 40=18 \pi r$

$\implies 293.6=18 \pi r$

$\implies r=\dfrac{293.6}{18 \pi}$

$\implies r=5.19 \sf \: units \:(2\:dp)$
