Distance (D) = Rate (R) * Time (T)

For Car  A:  

D = 30T    {Eqn 1}

For Car B:

The Distance D and the time T is the same as for Car A

But, unlike Car A, Car B travels at two different rates.  It travels at 20mph for a time T1.  Then it passes Car A and travels at a rate of x for a period of time T2.

D = (20T1) + (x * T2)

Note that T2 must equal the total time T minus T1, so

D = (20T1) + (x * (T - T1))    {Eqn2}

Substitute Eqn 1 into Enq 2 :   30T = 20T1 + xT - xT1

Rewrite as:  30T = 20T1 + x(T-T1)  {Eqn 3}

At what point do the two cars pass one another?  

Car A travels 30T1  = D1

Car B is traveling in the opposite direction at 20T1 = D2

D2 = D - D1 (where D is the total circular length of the track)

Substituting, 20T1 = D - 30T1.   Or 50T1 = D   {Eqn 4}

Now we can establish a relationship between T and T1 by substituting Eqn1 into Eqn4

D = 30T = 50T1

30T = 50T1

(30/50)T = T1

T1 = (3/5)T   {Eqn 5}

Now substitute Eqn 5 into Eqn 3

30T = 20T1 + x (T-T1)

30T = 20(3/5)T+ x (T - 3/5 T)

30T = 12T +  xT(2/5)

18T = (2/5)x

(5/2)18 = x

45 mph = x

Recall that x is the speed that Car B must travel after it passes Car A.

Answer:

(2, 1 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = (7, 3) and (x₂, y₂ ) = (- 3, - 1) , then

midpoint = ( [tex]\frac{7-3}{2}[/tex], [tex]\frac{3-1}{2}[/tex] ) = ( [tex]\frac{4}{2}[/tex], [tex]\frac{2}{2}[/tex] ) = (2, 1 )

Answer:

μx = 17

σx = 2.2

Step-by-step explanation:

See attachment for full question.

Given:

μ = 17

σ = 22

[tex]n = 100\σ = 22[/tex]

Required

Determine (i) μx and  (ii) σx

Solving (i): μx

The mean of a sample means is calculated as thus:

μx = μ

Hence:

μx = 17

Solving (ii): σx

σx = σ/√n

So, we have:

σx = 22/√100

σx = 22/10

σx = 2.2

Answer with step-by-step explanation:

First, we have to find out how much paint Kevin used. We can write the equation as the following; 5/1 × 7/8 = 4 3/8. Now, we divide 4 3/8 by 4 to calculate how much paint will be used for each wall. 4 3/8 ÷ 4 = 35/32. So to finalize, Kevin used 35/32 gallons to paint each wall.

Answer:

A) 0

B) 0

C) 0

D) 0.5

Step-by-step explanation:

We are told that Men have XY (or YX) chromosomes and women have XX chromosomes

A) If a father has the defective x chromosome and the mother has good XX chromosomes, the four possible outcomes will be;

{xX, YX, YX, xX}

The outcome for the son is;

{YX, YX}

The son will have the disease only if it's xY. Thus, probability of son having the disease is; 0/2 = 0

B) If a father has the defective x chromosome and the mother has good XX chromosomes, the four possible outcomes will be;

{xX, YX, YX, xX}

The outcome for the daughter is;

{xX, xX}

The daughter will have the disease only if it's xx. Thus, probability of daughter having the disease is; 0/2 = 0

C) If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, the possible outcomes are;

{xX, xY, XX, XY}

Outcome for daughter is {xX, XX}

The daughter will have the disease it's xx. Thus, probability of daughter having the disease is; 0/2 = 0

D) If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, the possible outcomes are;

{xX, xY, XX, XY}

The male outcome is;

{XY, xY}

The son will have the disease only if it's xY. Thus, probability of son having the disease is; 1/2 = 0.5

Answer:

m∠EHG = 68

Step-by-step explanation:

If the two ancient step pyramids are congruent,

ABCD ≅ EFGH

All the angles and sides of the two pyramids will be congruent.

By the property of congruence,

Base angles of both the pyramids will be congruent.

m∠ADC = m∠EHG = 68°

Therefore, m∠EHG = 68 will be the answer.

Answer:

They would produce 14,400 packages of zetsy and the regular profit making would be $11,340.

Step-by-step explanation:

12-ounce

regular = 65%

mild = 35%

extra sharp zesty blend = 75%

extra sharp mild = 25%

8,100 mild for = $1.30

3,500 extra sharp = $1.50

cost blend and package = $0.30

regular sold = $1.8

zesty = $2.10

first we calculate the cost of each product

conversion Of  ounces to pounds:

1 pound = 16 ounces

regular cost:

12/16 pounds x 65% mild x $1.30

= 0.63375

12/16 pounds x 35% sharp x $1.50

= 0.39375‬

+ blend and package $0.30

total = $1.3275‬

contribution: $1.8 – $1.3275

= $0,4725‬

zesty cost:

12/16 pounds x 75% mild x $1.30

= 0.73125‬

12/16 pounds x 25% sharp x $1.50

= 0.28125‬

+ blend and package 0.30

total $1,3125‬

contribution: $2.10 – $1.3125

= $0,7875‬

to maximize profit:

profit = $0.4725Regular + $0.7875zetzy

adding the  constraint:

mild = Regular x $0.4775 + Zetzy x $0.5625 = 8,100

and

sharp = Regular x $0.2625 + Zetzy x $0.1875 = 3,100

contribution generated by each product/pound:

                                 Regular        Zesty

CM                          $ 0.47250 $ 0.47250

Constrain resource

( pounds of mild)         0.48750 0.56250

CM per constrain        $ 0.9692 $ 1.4000

Constrain resource

( pounds of sharp)         0.26250 0.18750

CM per constrain           $ 1.80      $ 4.20

As zesty is better we produce as much as we can:

8,100 pounts / 0.5625 per cheese spreads: 14,400

check for possibilities of other constraint:

14,400 zesty packages x 0.1875 pounds each = 2,700 pounds

because it’s possible we only produce zetsy

profit = $0.4725 (0) + $0.7875 (14,400)

profit =  $ 11,340

You havent gaven enough information for me to solve the question, do i just freely pick how much magazine ads and tv ads i want until i get to 9k, im very confused

Step-by-step explanation:

Let's use the point-slope formula to write the equation of this line.

The point-slope formula is y - y₁ = m(x - x₁).

In the formula, x₁ and y₁ are points and the m is our slope

Now let's substitute.

y + 2 = -3/2(x - 6).

Notice that I put y + 2 above since y - (-2) means y + 2.

Now distribute the -3/2 through the parentheses.

This gives us -3/2x + 9.

Bring down your y + 2 and we have y + 2 = -3/2x + 9.

To put this in standard form, we need to multiply both

sides by 2 because we can't have any fractions.

This gives us 2y + 4 = -3x + 18.

Now move the +4 to the right by subtracting

4 from each side to get 2y = -3x + 14.

Now move your x term to the right by adding 3x to both sides.

So our final answer reads 3x + 2y = 14.

Answer:

$135

Step-by-step explanation:

first divide 36 by 8

gives you how much you earn for one hour

36/8=4.5

then multiply

4.5 by amount of hours worked

so 4.5*30=135

The amount of money earned on a job for 30 hours is $135.

The amount of money earned on a job is directly proportional to the number of hours worked.

The amount of money earned for 8 hours of work is $36.

We need to determine the amount earned for 30 hours of work.

Let us determine the amount earned per hour.

Thus,

[tex]\begin{aligned}8\;\rm{Hours \;of\;work}&=\$36\\1\;\rm{Hour \;of\;work}&=\$\dfrac{36}{8}\\&=\$4.5 \end{aligned}[/tex]

Therefore, the amount earned per hour is $4.5.

Now, multiply by 30 to get the amount earned for 30 hours.

Thus, the amount of money earned on a job for 30 hours is $135.
