Answer:

$0.79

Step-by-step explanation:

Answer:

$0.79

Step-by-step explanation:

There are two ways to solve this. You can either set it up as a proportion or just divide 8 by $6.32. Be careful if you just divide, however, that you don't divide it the wrong way. 8 divided by 6.32 will give you a different answer than 6.32 divided by 8. Setting up a proportion may be harder and longer, but it is definitely the safer way to go.

Proportion:       [tex]\frac{6.32}{8} = \frac{x}{1}[/tex]          6.32 = 8x     6.32 ÷ 8 = 0.79      x = 0.79

79 cents is your answer.

Answer:

x = 97

Step-by-step explanation:

a^2 + b^2 = c^2

(65^2) + (72^2) = c^2

4,225 + 5,184 = c^2

9,409 = c^2

√9,409 = 97 = c^2

97 = c

Answer:

75.36

Step-by-step explanation:

r = radius

pi = 3.14

You know the diameter (2*r) is equal to 24 feet

using the formula for diameter you get 2r = 24

now, you can either solve for r (radius) and plug radius into the formula for circumference OR you can use the 2*r value of 24 feet and plug that into the formula for circumference

if you solved for r directly, you would get r = 12

- then you plug r into the circumerference formula 2*pi*r (where pi  3.14) and you would get 75.36

if you used the diameter value of 2*r, all you would have to do is multiply the given diameter value by pi (3.14) and you would get 75.36

UNIT: feet

NOTE

- you can use the diameter value and simply multiply that by pi because the formula for diameter is 2*r and the formula for circumference is 2*r*pi  

I hope this helped :)  

Answer:

[tex]h=8.48\ \text{inches}[/tex]

Step-by-step explanation:

Given that,

Radius of cone, r = 7 inches

Slant height of the cone, l = 11 inches

We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :

[tex]h^2+r^2=l^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{11^2-7^2}\\\\h=8.48\ \text{inches}[/tex]

So, the height of the cone is equal to [tex]8.48\ \text{inches}[/tex].

About half of her students plan to take time off this summer.

Step-by-step explanation:

The generalization that can be made by the piano teacher is about half of her students plan to take time off this summer.

A survey is when a particular group of people are asked about their preferences or opinion on a particular subject matter. The piano teacher asked students from the classes on Monday through to Saturday if they would take time off.

The result was that 50% of the students would take time off. Thus, it can be generalized that about half of her students plan to take time off this summer.

Answer:

0.214285714

Step-by-step explanation:

when you divide the numbers, you get 0.214285714.

36/168 = 0.214285714

Answer:

3/14

Step-by-step explanation:

first starting from 36/168, you can divide both by 3, which would be 12/56. then you can divide both numbers by 4, which would become 3/14, which is the in the most simplified form.

These points can be described the following double inequality:  -3≤x≤13.

Inequality is a mathematical expression that does not present equality between both sides. It is represented by symbols: <, ≤, > and ≥.

When the variable x is between the both extremes, the inequality will be called double inequality. Therefore, the double inequality can be written in the form below .

As the interval is represented by a closed dot, your interval inequality must be represented by signs ≤ or ≥.

Thus, the points of this question can be described as: -3≤x≤13.

Step-by-step explanation:

he is putting in by the 3/5

Answer:

C.

Step-by-step explanation:

Why its C...

You can tell that on the top it say that the total is 15 so it can not be a. So now our answer choices are B, C, ad D.

Now it says that there are 3/5 highlighted but since the rest say 3/5 we can not eliminate yet.

Next we would multiply 3 x 3 to get 9 for how many dollars there are. Cross out B.

Between C and D, C is the most reasonable answer because it says how much did he put in the bank while the other one (D) says how much did he spend?

So it would be C

Answer:

[tex]Volume = x^3 +3x^2 -16x +12[/tex]

Step-by-step explanation:

Given [missing from the question].

The dimensions are:

Length =(x + 6), Width = (x - 2) and Height = (x -1)

Required

Represent the volume as a polynomial

Volume is calculated as:

[tex]Volume = Length * Width * Height[/tex]

So:

[tex]Volume = (x + 6) * (x - 2) * (x - 1)[/tex]

Expand

[tex]Volume = (x + 6) * (x^2 -2x -x +2)[/tex]

[tex]Volume = (x + 6) * (x^2 -3x +2)[/tex]

Expand

[tex]Volume = x^3 -3x^2 +2x +6x^2-18x +12[/tex]

Collect like terms

[tex]Volume = x^3 -3x^2+6x^2 +2x -18x +12[/tex]

[tex]Volume = x^3 +3x^2 -16x +12[/tex]

the distance between balloon A and balloon B IS 1005 Feet

Height is the measurement of an object in the vertical direction and distance is the measurement of an object from a particular point in the horizontal direction.

According to the question,

Angle ADC = 60  degree

Angle BDE = 82 degree

Ac = 1400 Feet

In right angle triangle ACD,

Tan(x)= AC/CD

Tan(60) = 1400/CD

CD = 1400/[tex]\sqrt{3}[/tex]

CD = 808.3

In triangle BDE,

Tan(y) = BE/DE

Tan(82) =  1400/DE   { Tan(82) = 7.115 }

DE = 1400/7.115

DE = 196.8

the distance between balloon A and balloon B =CD + DE

                                                                               = 808.3 + 196.8

                                                                               =   1005 Feet

Hence, the distance between balloon A and balloon b is 1005 feet

it should be greater than. the reasoning for this is if you equally split a rectangle into 3 pieces and then also split the same sized rectangle into equal pieces then which pieces would be bigger? the Rectanhle that is split into 3! this is because you have less pieces to split the rectangle into so the less you have too split the rectangle to larger the pieces are!!

Answer:

2/3+2/3 is greater than 1 1/4, so Edward does not have enough oil

Step-by-step explanation:

2/3+2/3=4/3, or 1 1/3

So now it's is 1 1/3 greater than or less than 1 1/4, which is just a matter of if 1/3 is greater than 1/4. 1/3 is 0.33 repeating, and 1/4 is 0.25, so 1/3 is greater than 1/4

1 1/4 is the amount of oil he has, and 1 1/3 is the amount required, which is more than he has so therefore he can't make 2 batches

The  equation that shows the total number of shoes and soxes he bought is x+y=5.

Step-by-step explanation:

Given that statement says that Andy bought total of 5 pairs of shoes and soxes this means that the equation would indicate that the sum of the number of pairs of shoes plus the number of pairs of soxes is equal to 5, which can be expressed as:

x+y=5

The other answers are not right because the numbers of pairs of shoes and soxes are multiplied by another number and the statement indicates that the pairs of shoes and soxes is equal to 5.
