a car travels 120 km in one and a half hours. what is the average speed

Answers

Answer:

The speed would be 60kph.

Answer:

80 mph (average)

Step-by-step explanation:

Split 120 into thirds, each one being half an hour.

120/3=40

Add two of them together, getting 80.

40x2(or 40+40)=80

Since the car travels 80 miles in one hour, 80 mph is the average speed.

Answer:  20% of the teachers are from district M

There are 50 teachers from district M, so bar M is 50 units tall.

=======================================================

Work Shown:

Let's add up the bar heights of the bars shown in the chart.

J+K+L+N = 50+80+30+40 = 200

So 200 teachers are from districts J,K,L, or N.

We're told that 250 total teachers attended. This must mean M = 50. We're effectively solving 200+M = 250.

So you'll need to draw a bar over M such that it is 50 units tall. This will complete the chart.

Because there are 50 teachers from district M, out of 250 total, we can then compute the percentage to get

50/250 = 0.20 = 20%

So 20% of the teachers are from district M.

The option second “with compass point at A, construct an arc of length OA intersecting the circle” is correct.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

To construct a regular hexagon in Circle O first mark point A then, with compass point at A, construct an arc of length OA intersecting the circle.

Thus, the option second “with compass point at A, construct an arc of length OA intersecting the circle” is correct.

Answer:

1.7%

Step-by-step explanation:

Simple interest (I) is calculated as

I = [tex]\frac{PRT}{100}[/tex] ← substitute values for I, P and T

17 = [tex]\frac{500(2)R}{100}[/tex] ( multiply both sides by 100 to clear the fraction )

1700 = 1000R ( divide both sides by 1000 )

1.7 = R

Answer:

Age of Nicole x= 24 years

Age of Donald = y = 48 years

Step-by-step explanation:

Sum of their ages is 72, therefore

[tex]x+y=72[/tex] -------------- (1)

Nicole is half as old as Donald

A group of nine friends go to a baseball game. The group buys 6 hotdogs and 3 hamburgers for a total of $27.75. A hamburger costs $1.75 more than a hot dog. What is the cost of a hamburger?

Answers

Answer:

let x be cost of a hotdog

let y be cost of hamburger

so,

5x + 4y = 17.75                    eq. 1

4x + 5y = 18.25                    eq. 2

manipulate eq. 1 so solve for x:

5x = 17.75 - 4y

x = 17.75/5 - (4/5)y

x = 3.55 - (4/5)y                  eq. 3

substitute eq. 3 to eq. 2:

4(3.55 - (4/5)y) + 5y = 18.25

14.2 - (16/5)y + 5y = 18.25

14.2 + (9/5)y = 18.25

(9/5)y = 18.25 - 14.2

4.05= (9/5)y

y = 2.25

x = 3.55 - (4/5)(2.25)

x = 1.75

hotdog costs $1.75

hamburger costs $2.25
