Two cars leave towns 760 kilometers apart at the same time and travel toward each other. One car's rate is 12 kilometers per hour less than the other's. If they meet in 4 hours, what is the rate of the slower car

Answers

Answer:

89 km/hr

Step-by-step explanation:

Distance = Rate(speed) × Time

D = R × T

T = 4 hours

One car's rate is 12 kilometers per hour less than the other's.

Hence:

First's car's rate = r × 4 = 4r

Second car's distance = (r + 12) × 4 = 4r + 48

4r + 4r + 48 = 760

8r + 48 = 760

8r = 760 - 48

8r = 712

r = 712/8

r = 89 km/hr

The rate of the slower car is 89 km/hr

no, 72 km/hr is equal to 20m per sec

Hey, There i hope you are haveing a great day :) So I look at the example so it should be the same I think like how you work out the mean by adding all the numbers and then diving them so,  (8 + 4 + 8 + 8 + 10 + 2 + 4 + 4) = 48 and now you know you have got 8 numbers there a divide them so 48/8 = 6. and then I think you take away it so, 8 - 6 = 2 4 - 6 =-2 8 - 6 = 2 8 - 6 = 2 10 - 6 = 4 2 - 6 = -4 4 - 6 = -2 4 - 6 = -2 and then 2 + -2 + 2 + 2 + 4 + -4 + -2 + -2 divide 8 = 0 and you can't divide anything by 0 so that would be the answer.

Predict the rate of change for the depth of the diver for the intervals of [3, 4], [4, 5], and [5, 6].

Answers

Answer:

The rate of change is 1

Step-by-step explanation:

Given

[tex]\{[3, 4], [4, 5], [5, 6]\}[/tex]

Required

Predict the rate of change

Average rate of change (R) is calculated using:

[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]

Here, we have:

[tex][a,f(a)] = [3,4][/tex] and

[tex][b,f(b)] = [5,6][/tex]

Substitute these values in the above equation

[tex]R = \frac{6 - 4}{5 -3}[/tex]

[tex]R = \frac{2}{2}[/tex]

[tex]R = 1[/tex]

Also, check the rate of change using:

[tex][a,f(a)] = [3,4][/tex] and

[tex][b,f(b)] = [4,5][/tex]

The equation: [tex]R = \frac{f(b) - f(a)}{b - a}[/tex] becomes

[tex]R = \frac{5-4}{4-3}[/tex]

[tex]R = \frac{1}{1}[/tex]

[tex]R = 1[/tex]

Hence, the rate of change is 1

A high school drama club is performing a musical to benefit a local charity. Tickets are $5. They also receive donations if $500. They wants to raise at least $2000. How many tickets should they sell to reach their target

Answers

Answer: 300 tickets

Step-by-step explanation:

The drama club wants to raise at least $2,000. They have already received donations of $500 so the amount left till target is:

= 2,000 - 500

= $1,500

Tickets are being sold at $5 so the number of tickets needed to get to $1,500 is:

= 1,500/5

= 300 tickets

Determine whether statement (3) follows from statements (1) and (2) by the Law of Detachment or the Law of Syllogism. If it does, state which law was used. If it does not, write invalid.(1) If you use a pencil you can erase mistakes. (2) If you can erase mistakes your paper will be neater. (3) If you use a pencil your paper will be neater. Question

Answers

Answer:

Law of Syllogism

Step-by-step explanation:

Remember, the Law of Syllogism simply states that if two statements are true, then a third statement that is true can be derived from it. In other words,

(1) If action p results in q , and

(2) If action q results in r.

Then we can derive a third true statement:  that says,

(3) If action p then r.

So in summary,

(1) If you use a pencil (action p), you can erase mistakes (results in q).

(2) If you can erase mistakes (q) your paper will be neater (r).

(3) If you use a pencil (if p) your paper will be neater (then r).

This rightly fits into the law of syllogism.

Find the equation of the line that passes through (1, -2) and is perpendicular
to the line joining the points (4, 2) and (-1, 7).

O y = -x - 3
O y = -x + 3
O y = -x + 6
O y = x - 3

Answers

Answer:

D. y = x - 3

Step-by-step explanation:

First, find the slope (m) of the line it is perpendicular to using the points of the line, (4, 2) and (-1, 7):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 - 2}{-1 - 4} = \frac{5}{-5} = -1 [/tex]

Thus, the slope (m) of the line that is perpendicular to the line that runs through (4, 2) and (-1, 7) would be the negative reciprocal of -1.

The slope (m) if the line that is perpendicular to the other line = 1

Thus, substitute m = 1 and (a, b) = (1, -2) into y - b = m(x - a)

y - (-2) = 1(x - 1)

y + 2 = x - 1

Subtract 2 from both sides

y = x - 1 - 2

y = x - 3

Write and solve a real-world problem that can be represented by the expression (–3)(5), then solve it

Answers

Answer and explanation:

(-3)(5) evaluates to -3×5=-15

A real world problem that would represent this would be a case where 5 fruit vendors each give out 3 fruits to 3 of their customers in the spirit of Christmas. Each vendor gives out(subtracts fruits from fruit stock) 3 of their fruits= -3 fruits for each vendor. There are a total of 5 fruit vendors therefore -3×5= -15 fruits given out by all 5 fruit vendors in total. To better understand this, we could compare this to if the vendor were to get(add to stock of fruits) fruits and not actually give out fruits. This would be 3×5= 15 fruits gotten by all the 5 vendors in total.
