Answer:

Trisha made 2 pans of brownies.

Step-by-step explanation:

Let the number of pans of brownies made by Trisha be 'x'.

Given:

Number of pans contributed by Rachel = 5

Number of squares in each pan = 12

Total number of squares (S) = 84

Total number of pans (N) = Number of pans by Trisha (x) + Number of pans by Rachel

So, [tex]N=x+5[/tex] -------- (1)

Total number of squares (S) = Number of squares in each pan × Number of pans (N).

[tex]S = 12N\\84=12N---- (2)[/tex]

Plug in the value of 'N' from equation (1) in equation (2). This gives,

[tex]84=12(x+5)[/tex]

Solve for 'x'.

[tex]12(x+5)=84\\\\x+5=\frac{84}{12}\\\\x+5=7\\\\x=7-5=2[/tex]

Therefore, Trisha made 2 pans of brownies.

Answer: Both Technicians

Step-by-step explanation: A drive shaft which is also called the propeller shaft,is a major part of a the drive train/ unit of a vehicle with the role of Transmitting TORQUE POWER TO THE WHEELS,it is usually made up of STEEL.

Drive shaft is elongated,it is round and it requires needle bearing for friction reduction and taping to prevent it from falling off when the shafts are removed during servicing. Both Technicians are correct as both options are needed.

Both technicians are correct. Technician A's suggestion to tape the U-joint caps is a preventative measure to prevent loss of needle bearings. Technician B is correct that needle bearings are used with U-joints.

Both Technician A and Technician B are correct in their assertions. Technician A's suggestion to tape the U-joint caps when servicing a drive shaft is a basic preventative measure to ensure they do not come loose and cause a problem. This is because losing a cap can lead to a loss of the needle bearings, which are crucial to U-joint function.

Technician B's statement is also correct that needle bearings are indeed used with these type of U-joints. Needle bearings allow the U-joints to rotate smoothly under the high pressure of the drive shaft. If the needle bearings were to fail or come out, it can cause the U-joint to fail.

Answer:the equation relating E to H is

E = 20H

Step-by-step explanation:

Let E represent her earnings (in dollars) after tutoring for H hours.

For each hour that she tutors, she earns 20 dollars. This means that in H hours, her total earnings would be

E = 20H

To find Mai's earnings after tutoring for 17 hours, we would substitute H = 17 into the equation. It becomes

E = 20 × 17

E = $340

Mai's earnings [tex](\(E\))[/tex] after tutoring for 17 hours would be $340, calculated as [tex]\(E = 20 \times 17\).[/tex]

To relate Mai's earnings [tex](\(E\))[/tex] to the number of hours she tutors [tex](\(H\))[/tex], we can use the following equation:

[tex]\[E = 20H\][/tex]

This equation represents that Mai earns $20 for each hour she tutors. By multiplying the number of hours [tex](\(H\))[/tex] by the rate of $20 per hour, we get her total earnings [tex](\(E\))[/tex].

Now, to find Mai's earnings after tutoring for 17 hours, we can plug in [tex]\(H = 17\)[/tex] into the equation:

[tex]\[E = 20 \times 17\][/tex]

[tex]\[E = 340\][/tex]

So, Mai's earnings after tutoring for 17 hours would be $340.

Answer: the number of hotdogs that were sold is 35

the number of orders of fries is 52

Step-by-step explanation:

Let x represent the number of hotdogs that were sold.

Let y represent the number of orders of fries.

You sold a total of 87 hotdogs and orders of fried combined. This means that

x + y = 87

Each hot dog costs 1.50 and each order of fries costs 0.50. At the end of the night you made a whopping $78.50! This means that

1.5x + 0.5y = 78.5 - - - - - - - - - - -1

Substituting x = 87 - y into equation 1, it becomes

1.5(87 - y) + 0.5y = 78.5

130.5 - 1.5y + 0.5y = 78.5

- 1.5y + 0.5y = 78.5 - 130.5

- y = - 52

y = 52

Substituting y = 52 into x = 87 - y, it becomes

x = 87 - 52

x = 35

Answer:

[tex]\sqrt{29}[/tex]

Step-by-step explanation:

The complex number x + yi can be expressed in coordinate form as

x + yi → (x, y ), thus

4 + 3i → (4, 3 )

6 - 2i → (6, - 2 )

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (4, 3) and (x₂, y₂ ) = (6, - 2)

d = [tex]\sqrt{(6-4)^2+(-2-3)^2}[/tex]

   = [tex]\sqrt{2^2+(-5)^2}[/tex]

   = [tex]\sqrt{4+25}[/tex]

Answer:

Amy's car tank capacity is 16 gallons.

Step-by-step explanation:

Let the capacity of the tank be 'x'

Given:

Amount of gas in the car till it is refilled = [tex]\frac{1}{8}\times x = \frac{1}{8}x \ gallons[/tex]

Amount of gas added = 14 gallons.

We need to find the capacity of the tank.

Solution:

Now we can say that

Total Capacity of the tank is equal to sum of Amount of gas in the car till it is refilled and Amount of gas added.

framing in equation form we get;

[tex]x=\frac{x}{8}+14[/tex]

Combining the like terms we get;

[tex]x-\frac{x}{8}=14[/tex]

Now making the denominators common we will use L.C.M.

[tex]\frac{8x}{8}-\frac{x\times1}{8\times1}=14\\\\\frac{8x}{8}-\frac{x}{8}=14\\\\\frac{8x-x}{8}=14\\\\\frac{7x}{8}=14[/tex]

Now multiplying both side by 8 we get;

[tex]\frac{7x}{8}\times 8=14\times8\\\\7x = 112[/tex]

Now dividing both side by 7 we get;

[tex]\frac{7x}{7}=\frac{112}{7}\\\\x=16\ gallons[/tex]

Hence Amy's car tank capacity is 16 gallons.

Answer:

  40 mph

Step-by-step explanation:

We assume "outbound" refers to the trip to the lake. The ratio of speeds is inversely proportional to the ratio of times, so ...

  outbound speed : inbound speed = 4 : 3

These differ by one ratio unit, so that one ratio unit corresponds to the speed difference of 10 mph. Then the 4 ratio units of outbound speed will correspond to ...

  4×10 mph = 40 mph

Paul's average speed on the outbound trip was 40 mph.

___

The distance to the lake was 120 mi.

Answer:Paul's average speed on the outbound trip is 40mph

Step-by-step explanation:

Let x represent Paul's outbound trip which is the trip to the lake.

The trip to the lake took 3 hours.

Distance travelled = speed × time

It means that

Distance covered on the trip to the lake would be

3 × x = 3x

the trip back took 4 hours. He averaged 10 mph faster on the trip there than on the return trip. It means that his speed would be

x - 10

Therefore, distance travelled on return trip would be

4(x - 10) = 4x - 40

Since the distance travelled is the same, it means that

3x = 4x - 40

4x - 3x = 40

x = 40

Answer: b) y = negative one fifthx + seven fifths

Step-by-step explanation:

Equation of a line in Slope intercept form : [tex]y=mx+c[/tex]   (1)

, where m is slope and c is constant.

Given : The equation of line LM is [tex]5x - y = -4.[/tex]

Convert it into slope- intercept form, we get

[tex]y=5x+4[/tex]

Comparing it to (1) , we get

[tex]m= 5[/tex]

Let [tex]m_1[/tex] be the slope pf the line perpendicular to LM.

Since the product of slopes of two perpendicular lines is -1.

Therefore , [tex]m_1\cdot m=-1\Rightarrow m_1=\dfrac{-1}{m}=\dfrac{-1}{5}[/tex]

Equation of line passing through (-3,2) and having slope [tex]m_1=\dfrac{-1}{5}[/tex] will be :-

[tex](y-2)=\dfrac{-1}{5}(x-(-3))\\\\ y-2=(-\dfrac{1}{5})(x+3)=\dfrac{-1}{5}x-\dfrac{3}{5}\\\\\ y=\dfrac{-1}{5}x-\dfrac{3}{5}+2=\dfrac{-1}{5}x-\dfrac{10-3}{5}\\\\\Rightarrow\ y=\dfrac{-1}{5}x+\dfrac{7}{5}[/tex]

Hence, the equation of a line perpendicular to line LM in slope-intercept form that contains point (−3, 2) is [tex]y=\dfrac{-1}{5}x+\dfrac{7}{5}[/tex].

Hence, the correct answer is b) y = negative one fifthx + seven fifths.

We want to find a line perpendicular to 5x - y = -4 that passes through the point (-3, 2). We will find that the line is: y = (-1/5)*x + 7/5

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Such that a line is perpendicular to the above one if and only the slope of this other line is the inverse of the opposite of the above slope, so the perpendicular line will be something like:

y = (-1/a)*x + c

Now we start with the line that we know, we need to find its slope:

5x - y = -4

We need to isolate y

y = 5x + 4

Then the slope of this line is a = 5, so the perpendicular line will be:

y = (-1/5)*x + c

Now we need to find the value of c such that the line passes through (-3, 2), this means that x = -3 and y = 2, then we have:

2 = (-1/5)*-3 + c

2 = (3/5) + c

2 - 3/5 = c

10/5 - 3/5 = c

7/5 = c

Then the equation is:

y = (-1/5)*x + 7/5

So the correct option is b.

Answer:the angles are 12 degrees, 48 degrees and 120 degrees.

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees.

The measures of the angles of XYZ are in the ratio 1:4:10. The total ratio is the sum of the proportion of each angle. It becomes

1 + 4 + 10 = 15

Therefore, the measure of the first angle would be

1/15 × 180 = 12 degrees

Therefore, the measure of the second angle would be

4/15 × 180 = 48 degrees

Therefore, the measure of the third angle would be

10/15 × 180 = 120 degrees

Answer:

a) (n²-n+m²-m)÷((n+m)×(n+m-1))

b)(n²+m²)÷(n+m)

c) part b is larger ,check below.

Step-by-step explanation:

a)If there are n white and m black balls ,total will be n+m balls. Let's find the probability of choosing two balls white.

First ball as white n÷(n+m)  second ball to be white again is n-1÷(n+m-1) the reason why we take away 1 is because we already chose one white ball in the beginning .So the probability will be product of these to get the both balls white.

Let's find the the probability of choosing both black.Same strategy ,first ball black  is m÷(n+m),second ball black is m-1÷(n+m-1).So the probability will be product of these to get the both balls black. We should add the final products and simplify

b)Because this time they are replacing the ball ,we will not take away 1.So to get both white probability is n÷(n+m) times n÷(n+m) .The probability of both black is m÷(n+m) times m÷(n+m).Add the products .

c) b will be always larger,We should compare the final products.

In b  (n²+m²) is divided by (n+m)

In a (n²-n+m²-m)÷((n+m)×(n+m-1))  less amount divided by a bigger value ,so it will result always with a smaller quotient

Answer:

the cylinder with height 6 has a volume of 60/π in³ greater than the volume of the cylinder with height 10 (option B , if 60π is changed for 60/π)

Step-by-step explanation:

The volume of a cylinder is

V= π*R²*H  (H=height)

since the length L of the piece of paper is L=2*π*R  →R=L/(2*π) (since is rolled to form the cylinder), then:

V= π*R²*H  = π*L²/(2*π)²*H  = L²*H/(4*π)

with L=10 in and H= 6 in we have

V₂= L²*H/(4*π)

the other way around is changing H for L

V₁= H²*L/(4*π)

the difference between the volumes will be

V₂- V₁ = L²*H/(4*π)  - H²*L/(4*π) = L*H *(L-H)/(4*π)  

replacing values

V₂- V₁ = L*H *(L-H)/(4*π)  = 10*6*(10-6)/(4*π) = 60/π in³  

then the cylinder with height 6 has a volume of 60/π in³ greater than the volume of the cylinder with height 10

Answer:

[tex]a=29000 -1.28*2400=25928[/tex]

Tires that wear out by 25928 miles will be replaces free of charge

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

[tex]X \sim N(29000,2400)[/tex]  

Where [tex]\mu=29000[/tex] and [tex]\sigma=2400[/tex]

And the best way to solve this problem is using the normal standard distribution and the z score given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

He wants to give a guarantee for free replacement of tires that don't wear weel so then we need to find a value a, such that we satisfy this condition:

[tex]P(X>a)=0.90[/tex]   (a)

[tex]P(X<a)=0.10[/tex]   (b)

Because we are interested in the lower tail.

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.  

As we can see on the figure attached the z value that satisfy the condition with 0.10 of the area on the left and 0.90 of the area on the right it's z=-1.28. On this case P(Z<-1.28)=0.10 and P(z>-1.28)=0.90

If we use condition (b) from previous we have this:

[tex]P(X<a)=P(\frac{X-\mu}{\sigma}<\frac{a-\mu}{\sigma})=0.1[/tex]  

[tex]P(z<\frac{a-\mu}{\sigma})=0.1[/tex]

But we know which value of z satisfy the previous equation so then we can do this:

[tex]z=-1.28=<\frac{a-29000}{2400}[/tex]

And if we solve for a we got

[tex]a=29000 -1.28*2400=25928[/tex]

So the value of height that separates the bottom 10% of data from the top 90% is 25928 mi.  

Tires that wear out by 25928 miles will be replaces free of charge

Answer:

Step-by-step explanation:

If the relationship between cost and the number of chairs produced is linear, we would write an equation that expresses this relationship in the slope intercept form. It is expressed as

y = mx + c

Where

m represents the slope

c = intercept.

Slope = (y2 - y1)/(x2 - 1)

y2 = final value of y = 4800

y1 = initial value of y = 2200

x2 = final value of x = 300

x1 = initial value of x = 100

Slope, m = (4800 - 2200)/(300 - 100) = 2600/200 = $13 per chair.

To determine the intercept, we will substitute y = 4800, x = 300 and m = 13 into y = mx + c. It becomes

4800 = 13×300 + c = 3900

c = 4800 - 3900 = 900

The equation becomes

y = 13x + 900

To write an equation that expresses the relationship between cost and the number of chairs produced, we need to find the slope and y-intercept of the linear equation. The equation that expresses this relationship is Cost = $26(Number of Chairs) - $400.

We must determine the slope and y-intercept of the linear equation in order to build an equation that describes the link between the price and the quantity of chairs produced.

Slope = Change in Cost / Change in Number of Chairs
Using the given values, the slope is (4800 - 2200) / (300 - 100) = $26 per chair.

Now, let's find the y-intercept. We can use either of the given data points. Substituting the values of one data point, we have:
$2200 = $26(100) + b
b = $2200 - $2600 = -$400.

Therefore, the equation that expresses this relationship is:
Cost = $26(Number of Chairs) - $400.
