Answer:

c=99

Step-by-step explanation:

Im assuming you mean 12 + (1/3c) - 36 = 9 in which case c=99 you can isolate c by combining 12 and -36, creating -24 and adding 24 on both sides making 1/3c=33, then multiplying both sides by 3 making c=99

and not

1) (12+1)/(3c-36)=9 ; c=12.48 or 12+13/27

2) (12+1)/3c -36=0; c=0.09629

Answer:

52 degrees

Step-by-step explanation:

We're given:

The sum of the two angles is 180 degrees, because they construct a straight edge together. A straight line has an angle measure of 180 degrees.

Knowing this, we can form the following equation and solve for x:

\(5x-2+2x=180\\7x-2=180\\7x=182\\x=26\)

Therefore, x is 26. Find 2x to find the measure of Angle 2:

\(2*26=52\)

Therefore, Angle 2 has a measure of 52 degrees.

Answer:

52

Step-by-step explanation:

Angle 1 and angle 2 are on a straight line so their measure add up to 180 and they are supplementary

m<1 + m<2 = 180

5x - 2 + 2x = 180 add like terms

7x - 2 = 180 add 2 to both sides

7x = 182 divide both sides by 7

x = 26

To find the measure of angle 2 replace x with the value we found

m<2 = 2x

2*26 = 52

Step-by-step explanation:

At the bottom of the histogram you see the number of prizes, the 4-7 prizes  bar goes up to 6 students.

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answer:

It will take them 8,100 minutes.

Step-by-step explanation:

If it takes a group of 24 students 1,296 minutes to study for an upcoming test, it takes 54 minutes for each student. (=> 1,296/24 = 54)

150 x 54 minutes = 8,100 minutes.

It will take them 8,100 minutes.

Answer: The total percentage decrease in the investor's stock account is 34%

Step-by-step explanation:

The investor's stock in Company A= $3800

The investor's stock in Company B= $3400

Percentage decline in stock of company A= 22%

Decline in value of stock of company A= 3800× 22/100

= 38×22

= $836

Percentage decline in stock of company B= 3400×12/100

= 34×12

=$408

Total decline in wealth of investor= 836+ 408

= $1244

Total percentage decline in wealth= 1244×100/7200

= 124400/7200

= 17.27%

The percentage decrease in investor's stock is 17.27%

Answer:

25

Step-by-step explanation:

4a +12 -2c + c

4( ) + 12 - 2( ) + ( )

4(4) + 12 - 2(3) + 3

16 + 12 - 6 + 3

28 - 6 + 3

22 + 3

25

Helping in the name of Jesus.

Therefore,  4a  +   12   -   2c   +   c  =   25

       a  =   4  

       c  =   3

        4a  +   12   -   2c   +   c

       (4)(4)  +  12  -     (2)(3)   +    3

         16     +   12   -   (2)(3)   +    3

         28      -            (2)(3)    +    3

         28     -   6     +     3

         22    +      3   =   25

Draw a conclusion:

     4a  +   12   -   2c   +   c   =  25

The answer to your RSM question is \(m=\frac{11}{10}\)

Step-by-step explanation:

It is given that the two ratios are equal.

How much bigger is the right side of the equation than the left side?

Eight times bigger because 7x8=56.

Therefore we divide the 3.2 by 8 and get 0.4.

We can make an equation to find m:

\(\frac{4}{11}m=0.4\)

You solve and you get \(m=\frac{11}{10}\)

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

x = -3 +/- sqrt(17)

Step-by-step explanation:

-((x^2) + 6x + 8) = 0

(x^2) + 6x + 8 = 0

(x + 3)^2 - 1 = 0

(x + 3)^2 = 1

x + 3 = +/- sqrt(1)

x + 3 = +/- 1

x = -3 +/- 1

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Answer:

The Range Stays 48°.

Step-by-step explanation:\

Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.

Hope this helps!

Answer:  B.  The range stays 48

Step-by-step explanation:

The largest answer is 105 and the smallest answer is 57.  The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest

Range = 105 - 57

Range = 48

The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.

So answer is B. The range stays 48

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

Explanation:

I'm assuming you meant to type 8x^2 + bx + 2 = 0

Compare this to ax^2 + bx + c = 0

We have a = 8, b = unknown, c = 2.

We'll use the discriminant formula which is D = b^2 - 4ac to find that

D = b^2 - 4ac

D = b^2 - 4*8*2

D = b^2 - 64

Since we want one real solution, we set the discriminant equal to zero.

D = b^2 - 64

0 = b^2 - 64

64 = b^2

b^2 = 64

b = sqrt(64) or b = -sqrt(8)

b = 8 or b = -8

So the equation 8x^2 + 8x + 2 = 0 has one solution. So does the equation 8x^2-8x+2 = 0
