Answer:

14 10 cent coins

Step-by-step explanation:

Assumption method:

Assume all are 10 cent

10x48=$4.80

8.20-4.80=3.40

10x47=$4.70

1x20=$0.20

$4.70+$0.20=$4.90

Gap= $3.40

Difference=$4.90-$4.80=$0.10

Gap÷Difference= $3.40÷0.10=34 20 cent coins

48-34=14 10 cent coins

I think its like this.

A circle has a circumference of 6. It has an arc of length 1.

s344n2d4d5 [400]

Answer:

60 degrees

Step-by-step explanation:

s = r (theta)

(theta) = s/r

= 1 / (3/π) = π/3

as a degree π/3 x 180/π = 60

60 degrees

*Circumference = 2πr

6 = 2πr

r = 6/2π = 3/π

THE DECIMAL 104.3 BECOMES 1,043 WHEN MULTIPLIED BY 10. THE SAME NUMBER BECOMES 10.43 WHEN MULTIPLIED BY 0.10 EXPLAIN WHY

cricket20 [7]

Since 0.10 is a decimal, multiplying 104.3 by 0.10 is actually dividing 104.3 by 10. Thus 104.3 multiplied by 0.10 is 10.43.

Complete the point-slope equation of the line through (2,3 and (7,4). Use exact numbers.

uysha [10]

The point-slope equation of the line is $y-3=\frac{1}{5}(x-2)$

Step-by-step explanation:

The form of the point-slope equation is $y-y_{1}=m(x-x_{1})$ , where

m is the lope of the line
$(x_{1},y_{1})$ is a point lies on the line

The slope of a line $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ , where

$(x_{1},y_{1})$ and $(x_{2},y_{2})$ are two points on the line

∵ The line through (2 , 3) and (7 , 4)

∴ $x_{1}$ = 2 and $x_{2}$ = 7

∴ $y_{1}$ = 3 and $y_{2}$ = 4

- Substitute these value in the rule of the slope

∵ $m=\frac{4-3}{7-2}=\frac{1}{5}$

∴ the slope of the line is $m=\frac{1}{5}$

Let us substitute the value of the slope and the coordinates of point $(x_{1},y_{1})$ in the form of the equation

∵ $y-y_{1}=m(x-x_{1})$

∵ $x_{1}$ = 2 and $y_{1}$ = 3

∵ $m=\frac{1}{5}$

∴ $y-3=\frac{1}{5}(x-2)$

The point-slope equation of the line is $y-3=\frac{1}{5}(x-2)$
