PLEASE HELP 15 POINTS!! I'm baffled

Mathematics
1 answer:
frez [133]4 years ago
5 0

Answer:

The solution that I am getting when simplifying this expression is

\sqrt{3} (x+3)^{\frac{1}{4} } which is also (\sqrt{3}) \sqrt[4]{x+3} As this is not one of the options I can only assume that there was a part of the answer that you were not able to write. If this is not the case, feel free to delete this response.

Step-by-step explanation:

First, I'd like to confirm that I have the right information

Expression: \sqrt{3\sqrt{x+3} }

a. (3+x)\sqrt{3}

b. 2x\sqrt{3}

c. 3+x\sqrt{3}

\sqrt{3\sqrt{x+3} }\\\\\sqrt{3} (\sqrt{\sqrt{x+3} } )\\\\\sqrt{3} (x+3)^{\frac{1}{4} }

Melissa buys a 10-pound box of apples. The box has 32 apples that are all identical. What is the weight of each apple in ounces?
Shalnov [3]

Answer:

Each apple weighs 5 ounces.

Step-by-step explanation:

This question can be solved using rules of three.

Each pound has 16 ounces.

So a 10-pound box will have 16*10 = 160 ounces

The box has 32 apples that are all identical. What is the weight of each apple in ounces?

So 32 apples have 160 ounces. How much does each apple weighs?

32 apples - 160 ounces

1 apple - x ounces

32x = 160

x = \frac{160}{32}

x = 5

Each apple weighs 5 ounces.

A fabricator is hired to make a 27 foot long solid metal railing for the stairs at a local library. the railing is 2.5 inches hi
Furkat [3]
The complete question in the attached figure

we know that
volume of <span>the railing=volume of a rectangular prism+volume </span><span>a half cylinder

convert 27 ft to inches--------> 27*12-----> 324 in
step 1
find the </span>volume of a rectangular prism
volume of a rectangular prism=L*W*H-----> 324*2.5*1.25-----> 1012.5 in³

step 2
find volume a half cylinder
volume a half cylinder=(1/2)*pi*r²*h
r=1.25 in
h= 324 in
volume a half cylinder=(1/2)*pi*1.25²*324---> 795.22 in³

step 3
volume of the railing=volume of a rectangular prism+volume a half cylinder
volume of the railing=1012.5+795.22------>1807.72  in³------> 1808 in³

the answer is
1808 in³

ZABD and ZCBD are adjacent. Given that m_ABC is 68º. MZABD= (2x + 5)º, and mZCBD= (3x+8)º, find mZCBD.
konstantin123 [22]

Answer:

I think that the required options are wrong.

Answer is given below with explanations.

mZCBD = 41 degrees

Step-by-step explanation:

from \: the \:  \: above \: mentioned \: diagram \\ we \: can \: say \: that \:  \\( angle \: ABD) + (angle \: DBC) = 68 \\ given \: that \:  \: angle \: ABD = 2x + 5 \\ and \: \:  angle \: CBD = 3x + 8 \\ on \: substituting \: the \: values \\ (2x + 5) + (3x + 8) = 68 \\ 5x + 13 = 68 \\ 5x = 68 - 13 \\ 5x = 55 \\ x =  \frac{55}{5}  \\ x = 11 \\ angle \: CBD = 3x + 8 \\  \:  \:  = 3(11) + 8 \\  \:  \:  = 33 + 8 \\  \:  \:  angle \: CBD= 41
