Answer:

1\frac{5}{8}

Step-by-step explanation:

When working with mixed numbers, the first thing you would want to do is make them into improper fractions so that they are easier to work with.

2\frac{3}{5} ÷ 1\frac{3}{5} = \frac{13}{5} ÷ \frac{8}{5}

To change the ÷ sign to a × sign, swap the denominators and the numerators of the second fraction.

\frac{13}{5} ÷ \frac{8}{5} = = \frac{13}{5} × \frac{5}{8}

Directly multiply. (Numerators with numerators and denominators with denominators)

\frac{13}{5} × \frac{5}{8} = \frac{65}{40}

Simplify to mixed numbers.

\frac{65}{40} = 1\frac{25}{40}

1\frac{25}{40} = 1\frac{5}{8}

Jack earns $40 in interest each year on an investment. What is his interest rate if his principal was $200
Fudgin [204]

Answer:

The interest rate is 20%.

Step-by-step explanation:

In order to calculate the interest rate, we need to compute how many percents the value he recieves is related to the total he invested. In this case he recieves 40 every year and he invested 200, to calculate that we will apply a rule of three. We have:

$200 -> 100%

$40 -> x%

200/40 = 100/x

200*x = 40*100

200*x = 4000

x = 4000/200 = 20

The interest rate is 20%.

1) g=-y+c/x, solve for X
Sindrei [870]

Answer:

the solution  x = \frac{c}{g-y}

Step-by-step explanation:

<u>Step 1:-</u>

Given problem g=\frac{-y+c}{x}

here l.cm is x

g = \frac{x y+c}{x}

cross multiplication we get ,

g x = x y +c

<u>Step 2</u>:-

subtracting x y on both sides , we get

g x - x y = c

taking common 'x' we get,

x(g-y) = c

<u>Final answer</u>:-

x = \frac{c}{g-y}

A circle with radius of 6 cm sits inside a circle with radius of 9 cm.
taurus [48]

Answer:

Equation for the area of a circle- π r²

The 2 radiuses are 6 and 9.

6 squared is 36 and 9 squared is 81.

The smaller one is 36π and the larger one is 81π.

The difference between them is the area of the shaded region.

81π - 36π = 45π

Use 3.14 for π.

45 x 3.14 = 141.3 u²

Hope this helps!
