Answer:

60 km/hr

Step-by-step explanation:

Let the speed at the initial average speed from Town X to Town Y be a.

We are told that it journeyed to Town Z at an average speed 20 km/h faster than its initial average speed. Thus, its average speed here is (a + 20) km/hr.

Town Y was 200 km from Town Z.

Thus, time spent here is;

t_2 = 200/(a + 20)

Time from X to Y is; t_1 = 150/a

We are told that it took the same time to travel for both parts of the journey.

Thus; t_1 = t_2

150/a = 200/(a + 20)

Cross multiply to get;

150(a + 20) = 200a

150a + 3000 = 200a

200a - 150a = 3000

50a = 3000

a = 3000/50

a = 60 km/hr

B. (b+3c)+(b+3c)

C. 2(b)+2(3c)

Step by Step instruction :)))

we have

2 (b+3c)

Distribute the number 2

2(b+3c) = 26 + 2(3c) = 26 + 6c

Verify each case

Case A) 3(b+2c)

distribute the number 3

3(b + 2c) = 36 + 3(2c) = 36 + 6c

3b + 6c is NOT equal to 2b + 6c

therefore

Choice A is not equivalent to the given expression

Case B) (b+3c)+(b+3c)

Combine like terms

b + 3c) + (b + 3c) = (b + b) = 3c + 3c = 26 + 6c

2b + 6c = 26 + 6c

therefore

Choice B is equivalent to the given expression

Case C) 2(b)+2(3c)

Multiply both terms by 2

2(b) + 2(3c) = 2b + 6c

2b + 6c = 26 + 6c

therefore

Choice C is equivalent to the given expression

The camera's final price will be $588.24.

Step-by-step explanation:

First you want to turn the percent into a decimal. 9.75%=.0975

Then, you want to multiply 535.98 by .0975.

You get $52.26 when you round to the nearest cent. The you add 52.26 to the original price and you get your answer!

Answer:

22.5/3

Step-by-step explanation:

Hey, the idea is to set up an equation that you can solve

36 ounces of tea = 3 cups(some ounces of tea) + 13.5 ounces left

Now just solve for how much tea is in each cup.

36-13.5 = 3(X)

3X = 22.5

x = 22.5/3

Answer:

x=3

Step-by-step explanation:

5(2x+1)=35

Step 1: Simplify both sides of the equation.

5(2x+1)=35

(5)(2x)+(5)(1)=35(Distribute)

10x+5=35

Step 2: Subtract 5 from both sides.

10x+5−5=35−5

10x=30

Step 3: Divide both sides by 10.

x=3

The required mean absolute deviation of the number of goals is 0.8.

The mean of the values is the ratio of the total sum of values to the number of values.

The mean absolute deviation of the number of goals is a measure of how far the individual scores deviate from the mean (average) score.

To find the mean (average) score:

Mean = (2 + 3 + 5 + 3 + 2) ÷ 5 = 15 ÷ 5 = 3

Next, we find the absolute deviation for each score:

Absolute deviation for score 2: |2 - 3| = 1

Absolute deviation for score 3: |3 - 3| = 0

Absolute deviation for score 5: |5 - 3| = 2

Absolute deviation for score 3: |3 - 3| = 0

Absolute deviation for score 2: |2 - 3| = 1

Mean absolute deviation is given as,
= (1 + 0 + 2 + 0 + 1) ÷ 5 = 4 ÷ 5 = 0.8

So, the mean absolute deviation of the number of goals is 0.8.

Answer:

y = 35x + 5

Step-by-step explanation:

Slope-intercept form is y = mx + b

m is the slope, b is the constant, or y-intercept.

In this case, 5 is our constant. You pay a one-time fee of $5 for a life jacket. This price doesn't change nor do you have to pay it again, so this is your constant.

35 is our slope. 35 represents the $35 you pay for each hour with the boat. This is our slope because it will change overtime, based on x, or the number of hours you are renting the boat.

y is the total cost, since you have to add up $35 times the number of hours you are renting, plus the $5 for the life jacket.

Answer:

The cost of the present is $22.20

Answer:

246.50

Step-by-step explanation:

Answer:

angles on a line add up to 180 degrees

180 - 40 = 140

180 degrees in a triangle. going to work out the base angles for the isosceles triangle as its top angle is 140 degrees.

180 - 140 = 40

base angles are equal so 40/2 = 20 degrees

X = 20 degrees

90 degrees angle has been indicated.

90-20 = 70

180 - 70 - 40 = 70

y = 70 degrees

Answer:

8.25

Step-by-step explanation:

(-10,-7) (-8,1) find the distance between the two points show work.

The formula for calculating the distance between the two points is expresses as;

D = √(x2-x1)²+(y2-y1)²

D = √(-8+10)²+(1+7)²

D = √(2)²+8²

D = √4+64

D = √68

D = 8.25

Hence the distance between the two points is 8.25

So, kids are divided into 8 total parts.

7 - 1 = 6 more parts that are boys. The 48 extra boys are those 6 parts.

48/6 = 8 boys per part

All parts have the equal number of kids, so one part girls also has 8.

There are 8 girls (and 56 boys. 8:56 = 1:7).
