hello like almost everyone else on here, I'm probably gonna fail so uh help, please? In your own words explain how to multiply/divide radical expressions? How do you know if you can or cannot simplify them?
Answer: It does not matter whether you multiply the radicands or simplify each radical first. You multiply radical expressions that contain variables in the same manner. As long as the roots of the radical expressions are the same, you can use the Product Raised to a Power Rule to multiply and simplify.

Answer:
∠ B = 54°
Step-by-step explanation:
The angles are supplementary, that is they sum to 180° , then
7x + 14 + 5x - 26 = 180 , that is
12x - 12 = 180 ( add 12 to both sides )
12x = 192 ( divide both sides by 12 )
x = 16
Then
∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°
a line has this equation:y=1/4x-1. what’s a perpendicular line that goes through (3,-8)
Answer:
y = -4x + 4
Step-by-step explanation:
y = (1/4)x - 1
m = (1/4)
Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/4)
[tex]= (-1)*\frac{4}{1}\\\\=-4[/tex]
(3 , -8)
y - y1 =m(x -x1)
y -[-8] = -4(x - 3)
y + 8 = -4x + 12
y = -4x + 12 - 8
y = -4x + 4

Find the solution to the situation “the number 629 divided by the number c equals 17”. Enter your answer in the box.
Answer:
the number c is 37
Step-by-step explanation:
The computation is shown below
If a number 629 is divided by the number c that equals to 17
So,
629 ÷ number c = 17
Now the number c is
= 629 ÷ 17
= 37
Hence, the number c is 37
find the length of the bold arc. Round your answer to the nearest tenth.
Answer:
62.83 m
Step-by-step explanation:
Given that,
The radius of the circle, r = 15 cm
Major angle = 240°
We need to find the length of the bold arc. The formula used to find the arc length is given by :
[tex]l=\dfrac{\theta}{360}\times 2\pi r\\\\=\dfrac{240}{360}\times 2\pi \times 15\\\\=62.83\ m[/tex]
So, the length of the bold arc is equal to 62.83 m.
find the volume of a prism 5 feet tall whose base is a right triangle with leg lengths 3/2 feet and 9 feet
Answer:
33.75
Step-by-step explanation:
The volume of a right triangle prism is 33.75 cubic feet which is 5 feet tall.
It is given that the prism is 5 feet tall whose base is a right triangle with leg lengths of 3/2 feet and 9 feet.
It is required to find the volume of the prism.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We have 5 feet tall prism ie.
height of the prism h = 5 feet
and base b = 3/2 feet
and length = 9 feet
We know the volume of the right triangle prism is given by:
[tex]\rm V = \frac{b\times h\times l }{2}[/tex]
Putting the values of b, h, and l, we get:
[tex]\rm V =\frac{\frac{3}{2} \times 5\times 9}{2}[/tex][tex]\rm V = \frac{3 \times 5\times 9}{2\times2} \Rightarrow \frac{135}{4}[/tex]
V = 33.75 cubic feets
Thus, the volume of a right triangle prism is 33.75 cubic feet which is 5 feet tall.

Amber is on a family cell phone plan with the other 2 members of her family. The family gets 744 shared cell phone minutes a month, and each family member is limited to his or her equal share of the minutes. The only free calls are calls between family members. How many minutes per day can Amber talk on her cell phone with her friends during a 31-day month, without going over her share of the minutes?
Answer:
8 Minutes
Step-by-step explanation:
When dividing 744 by 3 family members you will get 248 minutes, but then dividing by 31 to tell the number for how long they can all be on per day you will get 8. 744 ÷ 3 ÷ 31 = 8.
