Answer:

Larger number : 28

Smaller number : 14

Step-by-step explanation:

a + b = 42

a = 2b

2b + b = 42

3b = 42 (divide both sides by 3)

b = 14

a = 2 x 14

a = 28

in year 4 the store sold 112% of the total number of scooters sold during the previous three years combined determine the number

Margarita [4]

Answer:

2, 240

Step-by-step explanation:

In the table, the values should be

Year 1 725

Year 2 579

Year 3 696

Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.

$\frac{112}{100} =\frac{x}{2000}$

We solve through cross multiplication of numerator and denominator of the opposite fraction.

$112(2000)=100(x)\\224000=100x\\2,240=x$

Answer:

If 50.24cm = Circumference

Radius = 8cm

If 50.24cm^2 = Area

Radius = 4cm

Step-by-step explanation:

50.24cm what? Circumference? Area?

π = 3.14

2πr = Circumference

50.24 / 2π = r

r = 8

πr^2 = Area

50.24 / π = r^2

r^2 = 16

r = 4
