4.If D is the midpoint of CE, DE = 2x + 4, and CE = 6x + 2, then what is CD?

Answers

Answer:

1.   [tex]TV = 68[/tex]

2.  [tex]x = 7[/tex]

3.   [tex]x = 21[/tex]

4.    [tex]CD = 8[/tex]

Step-by-step explanation:

Solving (1):

Given

[tex]RT = 63[/tex]

[tex]RV = 131[/tex]

Required

Determine TV

To solve TV, we make use of the following formula;

[tex]RV = RT + TV[/tex]

Substitute values for RT and RV

[tex]131 = 63 + TV[/tex]

Make TV the subject of formula

[tex]TV = 131 - 63[/tex]

[tex]TV = 68[/tex]

Solving (2):

Given

[tex]MN = 26[/tex]

[tex]MP = x + 4[/tex]

[tex]PN = 2x + 1[/tex]

Required

FInd x

To solve x, we make use of the following formula;

[tex]MN = MP + PN[/tex]

Substitute values for MP, MN and NP

[tex]26 =x + 4 + 2x + 1[/tex]

Collect Like Terms

[tex]2x + x = 26 - 4 -1[/tex]

[tex]3x = 21[/tex]

Divide both sides by 3

[tex]x = 7[/tex]

Solving (3):

Given

[tex]HM = 4x - 12[/tex]

[tex]MJ = 3x + 9[/tex]

Required

Find x

Since M is the midpoint;

[tex]HM = MJ[/tex]

This gives

[tex]4x - 12 = 3x + 9[/tex]

Collect Like Terms

[tex]4x - 3x = 12 + 9[/tex]

[tex]x = 21[/tex]

Solving (4):

Given

[tex]CE = 6x + 2[/tex]

[tex]DE = 2x + 4[/tex]

Required

FInd CD

Since D is the midpoint;

[tex]CD= DE[/tex]

and

[tex]CE = CD + DE[/tex]

Substitute CD for DE

[tex]CE = DE + DE[/tex]

[tex]CE = 2DE[/tex]

Substitute values for CE and DE

[tex]6x + 2 = 2(2x + 4)[/tex]

Open Bracket

[tex]6x + 2 = 4x + 8[/tex]

Collect Like Terms

[tex]6x - 4x = 8 - 2[/tex]

[tex]2x = 6[/tex]

Divide both sides by 2

[tex]x = 3[/tex]

Recall that;

[tex]CD= DE[/tex]

So;

[tex]CD = 2x + 4[/tex]

Substitute 2 for x

[tex]CD = 2 * 2 + 4[/tex]

[tex]CD = 4 + 4[/tex]

[tex]CD = 8[/tex]

Help i dont understand Pls Help :( Given h(x)=4x-4h(x)=4x−4, solve for xx when h(x)=0h(x)=0.

Answers

Answer:

x=1

Step-by-step explanation:

So when it's h(5)= whatever equation you all the x in the equation to 5 and solve. When it says h(x)=0, it's asking you to find x for the equation to equal 0.

It's easy! all you have to do is set the equation to 0

so 4x-4=0

add 4 from both sides

4x = 4

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.

Answers

Step-by-step explanation:

z=y+16

y=y

:.z+y=5x where z=y+16

2y+16=5x

x=(2y+16)/5

.:z+y+x=180

y+16+y+(2y+16)/5=180

12y+80+16=900

y=67

z=16+67=83

Find the midpoint of the line segment with the given endpoints. 1) (-4, -9), (-6, -6)

Answers

Answer:

The answer is

[tex]( - 5 \: , \: - \frac{15}{2} )[/tex]

Step-by-step explanation:

The midpoint M of two endpoints of a given line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4, -9), (-6, -6)

The midpoint is

[tex]M = ( \frac{ - 4 - 6}{2} , \: \frac{ - 9 - 6}{2} ) \\ = ( - \frac{10}{2} , - \frac{15}{2} )[/tex]

We have the final answer as

Alan sells electronics, earning a base wage of $320 for one week, and a commission equal to 5% of his sales. he needs to earn at least $600 each week to cover his expenses. set up and solve an inequality to determine what Alans sales can be in order to ensure his expenses are covered.

Answers

Answer:

320 +0.05s ≥ 600sales ≥ $5600

Step-by-step explanation:

For sales of 's', Alan's earnings will be ...

  320 +0.05s

He wants that to be at least 600, so the inequality is ...

  320 +0.05s ≥ 600

__

Its solution is found by subtracting 320 and dividing by 0.05.

  0.05s ≥ 280

  s ≥ 5600

Alan's weekly sales must be at least $5600 for his earnings to cover his expenses.

the difference of a number and 6 is the same as 5 times the sum of the number and 2

Answers

Answer:

n - 6 = 5 * ( n + 2 ) ; n = -4

Step-by-step explanation:

For this problem, we will use the words to create an equation.  The left hand side of the equation will be the difference of a number and 6 and the right hand side of the equation will be 5 times the sum of the number and 2.  Hence, we can build the equation:

n - 6 = 5 * ( n + 2 )

If we wanted, we can solve the equation for the number, n.

n - 6 = 5 * ( n + 2 )

n - 6 = 5 * n + 5 * 2

n - 6 = 5n + 10

-16 = 4n

-4 = n

Thus, we have found the missing number to be negative four.

NarStor, a computer disk drive manufacturer, claims that the median time until failure for their hard drives is more than 14,400 hours. You work for a consumer group that has decided to examine this claim. Technicians ran 16 NarStor hard drives continuously for almost three years. Recently the last drive failed. The times to failure (in hours) are given in the following table. Give the test statistic.330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814

Answers

Answer:

The test statistics is  [tex]t  =  -1.727[/tex]

Step-by-step explanation:

From the question we are told that

The data given is  

   330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814

 The population mean is  [tex]\mu  =  14400[/tex]

    The  sample  size is  n =  16

  The  null hypothesis is  [tex]\mu \le  14400[/tex]

    The  alternative hypothesis is  [tex]H_a  :  \mu > 14400[/tex]

The sample mean is mathematically evaluated as

  [tex]\= x  =  \frac{\sum x_i}{n}[/tex]

So

   [tex]\= x  =  \frac{330+ 620+ 1870 +2410+ 4620+ 6396+ 7822+ 8102+8309+ 12882+ 14419+ 16092+ 18384 +20916+ 23812+ 25814 }{16}[/tex]

=>  [tex]\= x = 10799.9[/tex]

The  standard deviation is mathematically represented as

      [tex]\sigma =\sqrt{\frac{ \sum (x_i - \=x)^2}{n}} [/tex]

So

[tex]\sigma =\sqrt{\frac{(330- 10799.9)^2 + (620- 10799.9)^2+ (1870- 10799.9)^2 +(2410- 10799.9)^2 + (4620- 10799.9)^2 +(6396- 10799.9)^2 +(7822- 10799.9)^2 }{16}}  \ ..[/tex]

   [tex]..\sqrt{ \frac{(8102 - 10799.9)^2 +(8309 - 10799.9)^2 + (12882 - 10799.9)^2 + (14419 - 10799.9)^2 + (16092 - 10799.9)^2 + (18384 - 10799.9)^2 +(20916 - 10799.9)^2  }{16}} \ ...[/tex]

  [tex]\ ... \sqrt{\frac{(23812 - 10799.9)^2 +(25814 - 10799.9)^2 }{16}}[/tex]

=>  [tex]\sigma  =  8340[/tex]

  Generally the test statistic is mathematically represented as

  [tex]t =  \frac{10799.9- 14400}{ \frac{8340}{\sqrt{16} } }[/tex]

[tex]t  =  -1.727[/tex]

From the z-table  the p-value is  

     [tex]p-value  = P(Z > t) =  P(Z >  -1.727) =  0.95792[/tex]

 From the values obtained we see that

        [tex]p-value  >  \alpha[/tex]  so we fail to reject the null hypothesis

Which implies that the claim of the NarStor is wrong

Values of k for which the quadratic equation 2x - kx + k 0 has equal roots is
a)0only
b)4
c)8 only
d)0,8​

Answers

Answer:

The answer is D.

Step-by-step explanation:

We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :

[tex]D = {b}^{2} - 4ac[/tex]

[tex]let \: D = 0 ,a = 2,b = k,c = k[/tex]

[tex]0 = {k}^{2} - 4(2)(k)[/tex]

[tex] {k}^{2} - 8k = 0[/tex]

[tex]k(k - 8) = 0[/tex]

[tex]k = 0[/tex]

[tex]k - 8 = 0[/tex]

[tex]k = 8[/tex]

Adsila fills 9 boxes every hour. How many boxes does Carlos fill every hour?

Step-by-step explanation:

If Adsila made 9 boxes an hour for 6 hours,she made 54 boxes (9*6=54). Take how many she made away from the total (126-54=72). If Carlos made 72 boxes in 6 hours, divide 72 by 6 to get 12 (72/6=12). Carlos made 12 boxes an hour.

An ad for an above-ground pool states that it is 25 m2. From the ad, you can tell that the pool is a circle. If you swim from one point at the edge of the pool to another, along a straight line, what is the longest distance d you can swim? Express your answer in three significant figures.

Answers

Answer:

d ≈ 5.64 m

Step-by-step explanation:

We are told that the pool is circular and that the area is 25 m².

Now, the longest chord that connects two points in a circle is the diameter.

Thus, the longest distance d will be the diameter

Area of circle is given by the formula;

A = πr²

Thus;

25 = πr²

r² = 25/π

r = √(25/π)

r = 5/√π

Diameter is twice the radius. Thus;

d = 2 × 5/√π

d = 10/√π

d ≈ 5.64 m
