Step-by-step explanation:

c= 2(pi)r

c= 2(3.14)(11.4)

c=71.592

c= 71.6

2(3u-8)= 38

6u-16=38

take 16 on the other side..

6u = 38 +16

6u = 54

u = 9

Answer:

u=9

Step-by-step explanation:

Divide both sides by 2

3u-8=19

Add 8 to both sides

3u=27

divide both sides by 3

u=9

Answer:

C. 3 5/18

Step-by-step explanation:

What we know:

Joel purchased 5 7/9 lb of grapes, while Jim purchased 2 1/2 lb.

What we need to find out:

How many more pounds of grapes does Joel have than Jim.

What we need to do:

Subtract 2 1/2 from 5 7/9.

But first, we need a common denominator.

2 and 9 don't have any common factors so multiply normally.

2 * 9 = 18

5 7/9 becomes 5 14/18, and 2 1/2 becomes 2 9/18.

Now to subtract.

(5 - 2) + ((14-9)/18)

3 + ((14-9)/18

3 + 5/18

Joel has 3 5/18 more pounds of grapes than Jim, so the answer is C.

Answer:

C

Step-by-step explanation:

5 7/9 - 2 1/2 = 5 14/18 - 2 9/18 = 3 5/18

Answer:

y + 6 = 3/5(x - 4)  

Step-by-step explanation:

Point-slope is the general form y-y₁=m(x-x₁)

y1 = -6, x1 = 4

y - (-6) -> y +6

y +6 = 3/5(x - 4)

Answer:

x = -2 and y = -21

Step-by-step explanation:

Given equations are :

[tex]y=15x+9\ .....(1)\\\\y=\dfrac{x}{2}-20\ ....(2)[/tex]

From equation (1) and (2)

[tex]15x+9=\dfrac{x}{2}-20\\\\15x-\dfrac{x}{2}=-20-9\\\\\dfrac{29x}{2}=-29\\\\x=-2[/tex]

Put the value of x in equation (1)

y = 15(-2) + 9

= -30 + 9

y = -21

So, the solution of the equations are (-2,-21).

Answer:

Hi, I just wanted to say that I got this question a few days ago on my test!

I haven't gotten my grade yet and I dont know if I got it right but I hope you figure it out! Best of luck to you!

The equation of a line in point slope form is :

Y - y1 = m(x -x1)

M is the slope given as 8

Y1 and x1 are the x and y values of the given point:

Y - (-6) = 8(x - (-3))

Rewrite as:

Y + 6 = 8(x + 3)

The answer is D

Answer:

Step-by-step explanation:

From the given information.

An ordinal scale measurement does not give room to know the actual difference that coexists between the two measurements in a variable but in an interval scale of measurement, it is possible to deduce the actual difference that coexists between the two measurements in a variable.

Similarly, the ordinal scale only shows the rank of observations as per size and magnitude but in case of interval scale, it consists of classes with equal size, differentiated into direction and magnitude.

Answer:

The standard deviation of the age of the customers was of 2.08 years.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

[tex]\mu = 24[/tex]

85% of the customers are between the ages of 21 and 27 years.

Since the normal distribution is symmetric, this means, for example, that 27 is the 50 + (85/2) = 92.5th percentile, that is, when [tex]X = 27[/tex], Z has a pvalue of 0.925. So when [tex]X = 27, Z = 1.44[/tex]. We use this to find [tex]\sigma[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.44 = \frac{27 - 24}{\sigma}[/tex]

[tex]1.44\sigma = 3[/tex]

[tex]\sigma = \frac{3}{1.44}[/tex]

[tex]\sigma = 2.08[/tex]

The standard deviation of the age of the customers was of 2.08 years.

minutes: 47+34= 81 minutes= 80-60(one hour)=20 min leftover

seconds: 50+45=95 sec= 95-60(one min)= 35 sec leftover

Answer: Shorter side = 10 feet

Longer side = 24 feet

Hypotenuse = 26 feet

The side lengths of the triangle are 10ft, 24ft and 26ft.

Step-by-step explanation:

Let the length of the shorter leg be x.

The length of the longer leg of a right triangle is 4ft more than twice the length of the shorter leg. This will be: = 2x + 4

The length of the hypotenuse is 6ft more than twice the length of the shorter leg. This will be: = 2x + 6

Note that the square of the hypothenuse will be equal to the square of the other two sides. This will be:

x² + (2x + 4)² = (2x + 6)²

x² + (2x + 4)(2x + 4) = (2x + 6)(2x + 6)

x² + 4x² + 8x + 8x + 16 = 4x² + 12x + 12x + 36

x² + 4x² + 16x + 16 = 4x² + 24x + 36

5x² + 16x + 16 = 4x² + 24x + 36

Collect like terms

5x² - 4x² + 16x - 24x + 16 - 36 = 0

x² - 8x - 20 = 0

x² - 10x + 2x - 20 = 0

x(x - 10) + 2(x - 10) = 0

Therefore, x - 10 = 0

x = 10

a. length of the shorter side = 10ft

b. Length of the longer side = 2x + 4 = 2(10) + 4 = 20 + 4 = 24ft

c. length of the hypotenuse = 2x + 6 = 2(10) + 6 = 20 + 6 = 26ft

d. The side lengths of the triangle are 10ft, 24ft and 26ft.

Answer:

A. 0.72

Step-by-step explanation:

We take the amount spent on the necklaces and divide that by the amount she bought. So that would be $11.52/8. When we divide this, we get 1.44, and since this is not an option, I went and divided it by the two friends to get 0.72. So I believe A. would be the answer.

The cost for each necklace is given as $0.72.

In order to calculate the cost of one item, divide the total cost of items by the total number of items.

It is also called the unit rate of that item.

Total money spent on 8 neckless is $11.52.

The number of friends Rosa has 2.

Then, total number of  necklaces is 8 × 2 = 16

Now, the cost of each necklace can be calculated as,

Total cost of necklace ÷ Number of necklace

= $11.52 ÷ 16

= $0.72

Hence, the cost of each necklace for each of the friends is $0.72.

:

Trying to factor as a Difference of Cubes:

2.1      Factoring:  343x3-27  

Theory : A difference of two perfect cubes,  a3 - b3 can be factored into

             (a-b) • (a2 +ab +b2)

Proof :  (a-b)•(a2+ab+b2) =

           a3+a2b+ab2-ba2-b2a-b3 =

           a3+(a2b-ba2)+(ab2-b2a)-b3 =

           a3+0+0-b3 =

           a3-b3

Check :  343  is the cube of  7  

Check :  27  is the cube of   3  

Check :  x3 is the cube of   x1

Factorization is :

            (7x - 3)  •  (49x2 + 21x + 9)  

Trying to factor by splitting the middle term

2.2     Factoring  49x2 + 21x + 9  

The first term is,  49x2  its coefficient is  49 .

The middle term is,  +21x  its coefficient is  21 .

The last term, "the constant", is  +9  

Step-1 : Multiply the coefficient of the first term by the constant   49 • 9 = 441  

Step-2 : Find two factors of  441  whose sum equals the coefficient of the middle term, which is   21 .

     -441    +    -1    =    -442  

     -147    +    -3    =    -150  

     -63    +    -7    =    -70  

     -49    +    -9    =    -58  

     -21    +    -21    =    -42  

     -9    +    -49    =    -58
