Step-by-step explanation:

slope is rise over run so on this one you had to count down to -2 for the rise and count to 6 then simplify to make -1/3

The slope of the line will be equal to 1 / 3. The correct option is D.


What is a slope?

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is the ratio of the rise to the run.

The formula to calculate the slope of the line is,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The given coordinates of the point passing through the line are (-3,4) and (3,2).

The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 4- 2 ) / ( 3 + 3 )

Slope = 2 / 6

Slope = 1 / 3

Therefore, the slope of the line will be equal to 1 / 3. The correct option is D.

I the selling
selling prices is Rs 7777 and
His loss is Rs 888 . Find the cost price of radio-
price of a radio​

Answers

Answer:

The cost price of a radio is Rs 8665

Step-by-step explanation:

There is a relation between the cost price, loss amount, and the selling price.

In the loss, the cost price must be greater than the selling price.

The cost price = selling price + Loss amount

In our question:

The selling price is Rs 7777

The loss is Rs 888

We need to find the cost price

Let us use the rule above

∵ The selling price = Rs 7777

∵ The loss = Rs 888

→ Substitute them in the rule above to find the cost price

∴ The cost price = 7777 + 888

∴ The cost price = 8665

The cost price of a radio is Rs 8665

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends. If he works 6 hours on the weekend in addition to the 35 hours during the week, how much does he earn? A. What questions do you need to answer to solve the problem.

Answers

Answer:

$513.75

Step-by-step explanation:

Let h represent the number of hours he worked in a week

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.

Hence, his pay Is represented by equation:

$498.75 + $2.50 × x

If he works 6 hours on the weekend in addition to the 35 hours during the week

$498.75 + $2.50 × 6

= $498.75 + $15

= $513.75

Therefore, he earns $513.75

After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test are as follows. P(soil | high-quality oil) = 0.20 P(soil | medium-quality oil) = 0.80 P(soil | no oil) = 0.20 How should the firm interpret the soil test? The probability of finding oil is good. Given the probability of finding good soil, the oil company is more likely to find oil. What are the revised probabilities?

Answers

Answer:

The revised probabilities are;

The probability of finding soil with oil  = 0.8  

The probability of finding soil with good oil = 0.16

The probability of finding medium quality oil =  0.64

Step-by-step explanation:

The given probability of finding soil with high quality oil, P(QO) = 0.20

The probability of finding soil with medium-quality oil, P(OM) = 0.80

The probability of finding soil with no oil, P(ON) = 0.2

Therefore, given that the probability of finding soil with no oil = 0.2, we have;

The probability of finding soil with oil, P(OP) = 1 - the probability of finding soil with no oil

P(OP) = 1 - 0.2 = 0.8

Which gives;

The probability, P(FG) of finding soil with oil and that the oil is good is given as follows;

P(FG) = P(QO) × P(OP) = 0.2 × 0.8 = 0.16

The probability of finding good oil = 0.16

Similarly;

The probability of finding medium quality oil P(FM) =  P(OM) × P(OP) = 0.8 × 0.8 = 0.64

Which gives the revised probability as follows;

The probability of finding soil with oil, P(OP) = 0.8  

The probability of finding soil with good oil, P(FG) = 0.16

The probability of finding medium quality oil, P(FM) =  0.64.

Problem number 26 of the Rhind Papyrus says: Find a quantity such that when it is added to StartFraction 1 Over 4 EndFraction of itself the result is a 15. The modern day equation that models this problem is x plus StartFraction 1 over 4 EndFraction x equals 15.. What is the solution to the equation? x = 10 x = 12 x = 15 x = 30

Answers

Answer:

[tex] x = 12 [/tex]

Step-by-step explanation:

x = the quantity to find

This quantity added to ¼ of itself gives 15.

Thus, this problem can be represented as given above:

[tex] x + \frac{1}{4}x = 15 [/tex]

Solve for x

[tex] x + \frac{x}{4} = 15 [/tex]

[tex] \frac{4x + x}{4} = 15 [/tex]

[tex] \frac{5x}{4} = 15 [/tex]

Multiply both sides by 4

[tex] \frac{5x}{4}*4 = 15*4 [/tex]

[tex] 5x = 60 [/tex]

Divide both sides by 5

[tex] \frac{5x}{5} = \frac{60}{5} [/tex]

A plumber charges a $45 fee to make a house call and then $25 for each hour of labor. The plumber uses an equation in the form y = m x + b to determine the amount to charge each customer.

Answers

Answer:

Your final equation should be y = 25 x + 45

Step-by-step explanation:

    The equation y = m x + b represents any linear equation. the m stands for slope, and the b stands for the y- intercept (when x = 0). To fill in the blanks you need to figure out which piece of information is which.

    Let's start with the y intercept. y, in this equation stands for the cost. And since the y intercept is when x equals zero, you need the cost that doesn't relate to the time the plumber was at the house. That would be the 45 dollar fee you pay the plumber to go to your house.

    Next, let's explain why the 25 dollars represents m (The slope) of this equation. You have to pay the plumber 25 dollars for every hour he spends at your house, so this cost goes up by 25 dollars every hour.

Your final equation should be y = 25 x + 45

A rock is dropped from the top of a​ 2000-foot building. After ​second, the rock is traveling feet per second. After ​seconds, the rock is traveling feet per second. Let y be the rate of descent and x be the number of seconds since the rock was dropped. Part A: Write a linear equation that relates time x to rate y. (Hint: Use the ordered pairs (1,32) and (2,64) ) Part B: Use this equation to determine the rate of travel of the rock 17 seconds after it was dropped.

Answers

Answer:

[tex]y = 32x[/tex]

The rate is 224 ft/s

Step-by-step explanation:

Solving (a):

Given

[tex](x_1,y_1) = (1,32)[/tex]

[tex](x_2,y_2) = (2,64)[/tex]

Required

Determine the linear equation

First, we need to determine the slope using

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{64 - 32}{2 - 1}[/tex]

[tex]m = \frac{32}{1}[/tex]

[tex]m = 32[/tex]

The equation is then calculated using:

[tex]y - y_1= m(x - x_1)[/tex]

[tex]y - 32= 32(x - 1)[/tex]

[tex]y - 32= 32x - 32[/tex]

Add 32 to both sides

[tex]y - 32 + 32= 32x - 32 + 32[/tex]

[tex]y = 32x[/tex]

Solving (b):

Given

[tex]x = 7[/tex]

Required

Determine y

We have that:

[tex]y = 32x[/tex]

Substitute 7 for x

[tex]y=32 * 7[/tex]

[tex]y=224[/tex]

Hence, the rate is 224 ft/s

Yuto left his house at 10 a.M. To go for a bike ride. By the time Yuto's sister Riko left their house, Yuto was already 5.25 miles along the path they both took. If Yuto's average speed was 0.25 per minute and Riko's average speed was 0.35 per minute, over what time period in minutes,t, starting from when Riko left the house, will Riko be Behind her brother?

Answers

Answer:

The time period will be ;

10 am to 10 : 52 am

(Then she will catch up at exactly 10:52 am , 30 seconds)

Step-by-step explanation:

In this question, what we simply want to calculate is the amount of time it will take Riko to cover same distance as Yuto.

Mathematically, at any point in time;

Speed = distance/time

Let the time we are looking for be x minutes

At x minutes , Riko will be at a distance of 0.35 * x = 0.35x miles

At x minutes, Yuto will be at a distance of 5.25 miles + 0.25 * x = (5.25 + 0.25x) mikes

Kindly note that, at the time x minutes, the distance covered would have been equal;

Thus;

0.35x = 5.25 + 0.25x

0.35x -0.25x = 5.25

0.1x = 5.25

x = 5.25/0.1

x = 52.5 minutes

Over a time period of 52.5 minutes, Riko will be behind her brother ;

Since Yuto left at 10 am, the time period will be ;

10am to 10:52 am

Answer:

Sample Response: The solution means that Riko will be behind Yuto from the time she leaves the house, which corresponds to t = 0, until the time she catches up to Yuko after 52.5 minutes, which corresponds to t = 52.5. The reason that t cannot be less than zero is because it represents time, and time cannot be negative.
