Answer:

Felicia, these questions are tough for a lot of reasons, so it makes sense to me that nobody is giving you the right answers.   here is a right one  :)

Step-by-step explanation:

1st we need a strategy.  brainstorm :P   we are given the cost of material for boxes in area,  we are asked how much 12 boxes would cost.  let's find the area of the material for one box multiply that by the given cost. and then multiply that by 12  for the total cost.  seem good?  Yes there are other good ways to solve this problem if you're thinking that.  this is just how I'm arbitrarily choosing to solve it.

1) surface area of prism box

1a) triangles on ends

1/2* b*p  ( I think 6.2 is P for you, not positive about that)

1/2*6.4*6.2= 19.84  

1b) flat sides

6.4*25 =160 ( this is B )

1c) add up the 5 sides

160*3 + 19.84 * 2  = 839.68 [tex]cm^{2}[/tex]

2) find the cost on 1 box

839.68 [tex]cm^{2}[/tex] *  $0.0001 = 0.8397

about $0.84

3) find the cost for 12 boxes

0.8397 * 12 = 10.076

about $10.08

try those answers :)

Answer:

2t-7

Step-by-step explanation:

Not sure what you need ;( hope this helps!

answer:

2t−7

step-by-step explanation:

distribute:

=(2)(t)+(2)(−4)+1

=2t+−8+1

combine like terms:

=2t+−8+1

=(2t)+(−8+1)

=2t+−7

good luck :)

hopefully, this helps

have a great day !!

Answer:

$3200

Step-by-step explanation:

First divide 40,000 by 100, which givse you 400

Now multiply the 400 by 8, which mulitplies to 3200.

Answer:

8% as a decimal is .08

simply multiply the 40,000 by .08.

40000 x .08= 3200

Answer:

Step-by-step explanation:

area of triangle is 1/2xbasexheight.

So the answer would be 18. GL!

_______

1/2bh

so 1/2 12x3

1/2x36.

and that equals 18! <3

Answer:18

Step-by-step explanation:

Remember- area of triangle = bh/2

So, 12 x 3

36

–––

2

So, 18 inch ^2

Answer:

  D) $304.47

Step-by-step explanation:

The value of the account is found using the compound interest formula:

  A = P(1 +r/n)^(nt)

where interest rate r compounded n times per year for t years is applied to principal P.

  A = $300(1 +0.0148/365)^(365·1) ≈ $304.47

Answer:

D

Step-by-step explanation:

Answer:

a. no the graph fails the vertical line test

Answer: 61.6%

Step-by-step explanation:

The afternoon humidity average is 20% of the morning average.

The morning average is 77% so the afternoon average must be:

= Morning average * ( 1 - percentage decrease)

= 77% * (1 - 20%)

= 77% * 80%

= 61.6%

Answer:

We know that in a triangle, if two angles have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units

Answer:

AB=9

Step-by-step explanation:

[tex]\frac{DC}{BC}=\frac{EC}{AC}\\ \frac{4}{3}=\frac{16}{AC}\\\\ AC=12\\\\ AB=AC-BC\\ AB=12-3=9[/tex]

Answer:

136

Step-by-step explanation:

For the second question, it is 136 because for triangles all side when added always equal to 180, so if you add 24 and 20 (which = 44) and subtract it from 180, it gives you 136, which is the answer and the angle of n.

Answer:

hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

Step-by-step explanation:

Answer:

Slope-intercept form is

y = mx + b

We want to get the y by itself on one side of the equation.

0 = 18x + 6y – 2

First let's subtract 6y from both sides.

-6y = 18x – 2

Next let's divide both sides by -6.

y = (18 / -6)x - (2 / -6)

y = -3x + 1/3

...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)

Answer:

$25

Step-by-step explanation:

10*2=20

20+5=25

Answer: x=112

Step-by-step explanation: If you add 35 and 33 you would get 68 and if you subtract 68 from 180 you will get 112. I hope this helps!

Step-by-step explanation:

Answer:

[tex](3x+1)[/tex]

[tex](x+4)[/tex]

Step-by-step explanation:

Assuming that the given surface is two-dimensional, one can simply factor the given polynomial to find the dimensions of the surface.

[tex]3x^2 + 13x + 4[/tex]

Just by looking at the polynomial, it is fairly obvious that the factors are;

[tex](3x+1)(x+4)[/tex]

One can check this by distributing, multiply every term in one of the parenthesis by every term in the other. Then combine like terms,

[tex]3x^2 + 12x + x + 4\\\\3x^2 + 13x + 4[/tex]

Without further information, it is impossible to determine which is the length, and which is the width, one just knows that the dimensions of the surface are;

[tex](3x+1)\\\\(x+4)[/tex]

Answer:

A. 6.96 square cm

Step-by-step explanation:

A = 5.8 x 2.4 x 1/2

A = 5.8 x 1.2

A = 6.96

Hope that helps!

Answer:

6.96

Step-by-step explanation:

The area of a triangle is base times height over 2. The base is 5.8 and the height is 2.4. The product of these numbers is 13.92. We now have to divide this by 2. This gives our final answer of 6.96
