Give the correct answer step by step​

Answer:

a=2, b=2, c=-12

Step-by-step explanation:

Since it's in factor form, you would first distribute using foil to get [tex]2x^{2} -4x+6x-12[/tex] and then combine like terms when necessary. In this case, the fully simplified version is [tex]2x^{2} +2x-12[/tex]. Therefore your a is 2, b is 2, and c is -12.

Answer:

33.33

Step-by-step explanation:

Answer:

$33.3333333333 or 33 dollars and 33 cents

Step-by-step explanation:

Convert 1/6 into a decimal

which is 0.16666666666667

then do 200 times 0.16666666666667

and you get 33.3333333333

Alt:

200 times 1 divided by 6

which is also 33.3333333333

Answer: 2205

Step-by-step explanation:

Ratio of the number of students accepted to the number of students applying for admission = 2:7

Number of students accepted = 630 students

Number of students that applied will then be represented by x. This will be:

2/7 = 630/x

2 × x = 630 × 7

2x = 4410

x = 4410/2

x = 2205

The number of students that applied to the university was 2205

Answer:

2x + 3

Step-by-step explanation:

6x + 9 = 3*2 *x + 3*3 = 3*(2x + 3)

[tex]\frac{6x+9}{3}=\frac{3*(2x+3)}{3x}=2x + 3[/tex]

Answer:

2x+3

Step-by-step explanation:

(6x+9)/3                6/3=2, 9/3=3

2x+3

Answer:

[tex]Probability = \frac{8}{25}[/tex]

Step-by-step explanation:

Given

See attachment for graph

Required

Determine the probability of getting a score of 8 - 11 points in the next game

From the attachment, the frequency of the class 8 - 11 is:

[tex]Class\ 8 - 11 = 8[/tex]

Also, from the attachment, the total frequency is:

[tex]Total = 3 + 5 + 8 + 6+2+1[/tex]

[tex]Total = 25[/tex]

The required probability is:

[tex]Probability = \frac{n(8 - 11)}{Total}[/tex]

[tex]Probability = \frac{8}{25}[/tex]

Answer:

Step-by-step explanation:

3/4 of 3/8 is 0.28125 or 9/32

Answer:

Step-by-step explanation:

3/8 (left over - from party) of 3/4 : 3/4 of 3/8 = 9/32

Answer:

1- 3520

2- 3328

3- 30

4- 3432

Step-by-step explanation:

========================================================

Explanation:

To find the prime factorization, we'll start by dividing 180 by the smallest prime number

Divide 180 by 2 to get 180/2 = 90

Divide that by 2 to get 90/2 = 45

Then note how 45/2 = 22.5 isn't a whole number, so that means we move onto the next prime number 3

45/3 = 15

15/3 = 5

The denominators we used, in order, were: 2, 2, 3, 3

This means that 2*2*3*3 is part of the factorization. We can condense that to 2^2*3^2

The last term 5 is the final missing piece of the factor puzzle

Meaning, 2^2*3^2*5 = 180

I recommend you use a calculator to confirm this.

Answer:

25%

Step-by-step explanation:

Answer:

25,390

Step-by-step explanation:

The computation is shown below

Given that

There is a number i.e. 25387

Based on the above information

The given numbers should be written in 4 significant figures

So here the number after considering 4 significant figures is 25,390

Hence, the above represents the answer

Answer:

I think it would be finding the quantity in each group.

Step-by-step explanation:

Because there would be more than 1 group. there is only one group. so you are trying to find the number of hours each person in the group will get.

i think that is right sorry if not.

Answer:

The quantity, the kids would be the groups, we are not looking for the number of kids because we already know that. We're looking for the amount, or quantity each group (kids) gets.

Answer:

40

Step-by-step explanation:

because to find surface area, you need to know this formula: length * width * height.

so, 5 * 1 * 8 is 40

Answer:

hello did you find the answer

Answer:

Use the formula for the volume of a triangular pyramid: V=13Ah , where A = area of the triangular base, and H = height of the pyramid.

Given:

The system of equation is

[tex]y=-8x-3[/tex]

[tex]x+y=7[/tex]

To find:

Whether (3,4) is a solution of the given system or not.

Solution:

We have,

[tex]y=-8x-3[/tex]          ...(i)

[tex]x+y=7[/tex]            ...(ii)

Putting the value of y in (ii) from (i), we get

[tex]x+(-8x-3)=7[/tex]

[tex]x-8x-3=7[/tex]

[tex]-7x=7+3[/tex]

[tex]-7x=10[/tex]

Divide both sides by -7.

[tex]x=\dfrac{10}{-7}[/tex]

[tex]x=-\dfrac{10}{7}[/tex]

Putting [tex]x=-\dfrac{10}{7}[/tex] in (i), we get

[tex]y=-8\times (\dfrac{-10}{7})-3[/tex]

[tex]y=\dfrac{80}{7}-3[/tex]

[tex]y=\dfrac{80-21}{7}[/tex]

[tex]y=\dfrac{59}{7}[/tex]

So, the only solution of the given system is [tex]\left(-\dfrac{10}{7},\dfrac{59}{7}\right)[/tex].

Hence, (3,4) cannot be a solution of given system, Hence the correct option is B.

Answer:

66.7%

Step-by-step explanation:

Given that,

Weight in first five weeks = 4.5 pounds

Weight at eight weeks = 7.5 pounds

We need to find the increase in precentage. The percentage increase in any value is given by :

[tex]\%=\dfrac{\text{final-initial}}{\text{initial}}\times 100\\\\=\dfrac{7.5-4.5}{4.5}\times 100\\\\=66.7\%[/tex]

So, the increase in precentage is 66.7%.

Answer:

A. 12

Step-by-step explanation:

$1,150.89 - $200.13 = $950.76

$950.76 / $79.23 weekly = 12 weeks

To check:

12 weeks x $79.23 = $950.76

$950.76 + $200.13 = $1,150.89

Answer:

angle ABC is 130 degrees

Step-by-step explanation:

This is the quickest and simplest way to gind the answer.

Angle CBD and angle ABC are linear pairs. Linear pairs are supplementary meaning angle CBD and angle ABC equal 180 degrees. Since angle CBD is 50 degrees and you know both angles need to add up to 180 degrees all you need to do is subtract 180 from 50 degrees.

Answer:

Step-by-step explanation:

sin30=a/17

a=17sin30

a=8.5 m

3.5 or 7/2 if you need a fraction

Its 20 because, 32 -  9 = 23 and your rounding so its 20
