Answer:
[tex]\sqrt{180}[/tex] and [tex]6\sqrt{5}[/tex]
Step-by-step explanation:
The easiest way to solve this problem is to look at all the simplified radicals on the right. Then un-simplify them by bringing the coefficients under the radical. If the radican (value under the radical) of the radical on the right is equal to the radican on the left, then the two radicals are equal.
To un-simplify a radical, one will square the coefficients and then multiply that value by the current radican of expression. The result is the un-simplified value of the radical.
A.
[tex]3\sqrt{15}\\\\= \sqrt{15*(3)^2}\\\\=\sqrt{15*9}\\\\=\sqrt{135}[/tex]
[tex]\sqrt{45} \neq \sqrt{135}\\\sqrt{45} \neq 3\sqrt{15}[/tex]
B.
[tex]3\sqrt{5}\\\\=\sqrt{5*(3)^2}\\\\=\sqrt{5*9}\\\\=\sqrt{45}[/tex]
[tex]\sqrt{75} \neq \sqrt{45}\\\sqrt{75} \neq 3\sqrt{5}[/tex]
C.
[tex]9\sqrt{6}\\\\=\sqrt{6*(9)^2}\\\\=\sqrt{6*81}\\\\=\sqrt{486}[/tex]
[tex]\sqrt{54} \neq \sqrt{486}\\\sqrt{54} \neq 9\sqrt{6}[/tex]
D.
[tex]6\sqrt{5}\\\\=\sqrt{5*(6)^2}\\\\=\sqrt{5*36}\\\\=\sqrt{180}[/tex]
[tex]\sqrt{180}=\sqrt{180}\\\sqrt{180}=6\sqrt{5}[/tex]
A hexagon is inscribed in a circle As see in the picture.Find the length of an arc between consecutive vertices. Round to the nearest hundred
Need help homework
Answer:
The length of the arc between consecutive vertices is:
[tex]S=8.38\: in[/tex]
Step-by-step explanation:
The angle between consecutive vertices is 60°, it is because it forms an equilateral triangle.
Now, the length arc is defined as:
[tex]S=R\theta[/tex]
Where:
R is the radius (R = 8 in)θ is the angle of the arcWe see the angle is in grades, but we need to convert it to radians.
[tex]\theta=\frac{60^{\circ}}{360^{\circ}}(2\pi)[/tex]
[tex]\theta=1.05\: rad[/tex]
Finally, the length of the arc between consecutive vertices will be:
[tex]S=8*1.05[/tex]
[tex]S=8.38\: in[/tex]

The Peak Library Book Club was doing a bake sale. Their goal was $550 for the entire week. The sale has lasted 4 days so far and each day they raised about $135.50. Will they make their goal by day 4? If not, how much do they need on day 5 to meet it?
Answer: See explanation
Step-by-step explanation:
Since their goal was $550 for the entire week and the sale has lasted 4 days already and each day they raised about $135.50, the amount raised for the 4 days will be:
= $135.50 × 4
= $542.00
No, they won't make their goal by the 4th day.
The amount needed on the 5th day will be:
= $550 - $542
= $8
They'll need $8 on the 5th day.

answer BD is 108
Step-by-step explanation:
60^2+x^2=85^2

×^2=3625
Sq root both sides
x= 60
60+48=108

A pool is 6/7 full of water. If 1/6 of the water leaks out, how full will the pool be?
Subtract 1/6 from 6/7
First rewrite the fractions to have a common denominator:
6/7 = 36/42
1/6= 7/42
Now you have 36/42 - 7/42 = 29/42
The pool is 29/42 full

the formula for the volume of a cone is V=1/3hπr²
549.5 = 1/3(21)(3.14)(x)^2
549.5 = 7(3.14)(x)^2
549.5 = 21.98(x)^2
549.5 = 21.98(x)^2
divide by 21.98 on both sides
25 = (x)^2
sqrt 25 = sqrt x^2
5 = x

the formula for the volume of a sphere is V=4/3πr^3

v=3052.08

the formula for the volume of a sphere is V=4/3πr^3
523=4/3(3.14)r^3
523=4/3(3.14)r^3
523=(4.186)r^3
divide by 4.186 on both sides
124.92=r^3
cube root on both sides
4.998=r
