Answer:

21.8 square units

Step-by-step explanation:

The shaded area is made up of two sectors. Each sector has a central angle of 50 degrees.

Add the two 50 deg angles, to get 100 deg.

The shaded area is the are of a sector with 100-deg central angle.

$A_{sector} = \dfrac{n}{360^\circ}\pi r^2$

where n = measure of central angle of sector.

$A_{sector} = \dfrac{100^\circ}{360^\circ}(\pi)(5^2)$

$A_{sector} = 21.8~square~units$

Bobby put 1/3 of his lawn mowing money into his savings and uses the remaining 2/5 to buy a video game. If he has $12 left, how

Alexeev081 [22]

Given:

Bobby put 1/3 of his lawn mowing money into his savings

He uses the remaining 2/5 to buy a video game.

He has $12 left.

To find:

The amount did he have at first.

Solution:

Let x be the initial amount.

Bobby put 1/3 of his lawn mowing money into his savings. So, the remaining amount is

$x-\dfrac{1}{3}x=\dfrac{2}{3}x$

He uses the remaining 2/5 to buy a video game. Then the remaining amount is

$Remaining=\dfrac{2}{3}x-\dfrac{2}{3}x\times \dfrac{2}{5}$

$Remaining=\dfrac{2}{3}x-\dfrac{4}{15}x$

$Remaining=\dfrac{10x-4x}{15}$

$Remaining=\dfrac{6x}{15}$

$Remaining=\dfrac{2x}{5}$

It is given that the remaining amount is $12.

$12=\dfrac{2x}{5}$

$12\times 5=2x$

$60=2x$

Divide both sides by 2.

$\dfrac{60}{2}=x$

$30=x$

Therefore, Bobby have $30 at first.

Luda [366]

Answer:

b = -1.8

Step-by-step Solution:

Subtract or add to obtain your answer.

b + (−1.9) = −3.7
=> b - 1.9 = -3.7
=> b = -3.7 + 1.9
=> b = -1.8

Hence, the value of b is -1.8
