1. 1.1 kg

2. 1.8 kg

3. 5.5 kg

4. 4.7 kg

2.5 lbs * (1 kg/2.2 lbs) =

Solve the proportion using number sense. 2/8 = x/ 48

1. 6

2. 12

3. 16

4. 8

8 * 6 = 48

so what is 2 times 6 ?

or another way

1/4 * 48 = 12

Solve the proportion using cross products. 18/20 = k/110

1. 99

2. 122

3. 3.3

4. 2.9

20 k = 18*110

2 k = 18 *11

k = 9 * 11

Are the ratios 8/12 and 10/25 proportional? Explain

8/12 = 2/3

10/15 = 2/3 so no way 10/25 is 2/3

Which of the following is an equation of the line that crosses through (-3,4) and (3,6)?
Mama L [17]

Answer:

y=(1/3)x+5

Step-by-step explanation:

Slope-intercept: y=mx+b

m=((y2-y1)/(x2-x1)) = (6-4)/(3+3)= 2/6= (1/3)

y=(1/3)x+b

plug in one of the points (3,6)

6=(1/3)(3)+b

6=1+b    5=b

Answer:

Step-by-step explanation:

The diameter of each curved path is 200 feet. Since the two curved semi circular paths are equal, they would form a circle. It means that the distance around the two semi circular paths would be the circumference of the circle. Formula for determining the circumference of the circle is π × diameter. It becomes

200 × 3.14 = 628 feet

Total distance around the track would be

300 + 300 + 628 = 1228 feet

5280 feet = 1 mile

1228 feet = 1228/5280 = 0.23 mile

If he runs around the track exactly 15 times, it means that the number of miles covered is

0.23 × 15 = 3.45 miles

Since he will collect $4.50 for every mile he runs, the amount of money that he collected is

4.5 × 3.45 = $15.5
