Please help. Calculate the area of the shaded region in each figure use 3.14 for π and round to the nearest 10th if necessary

denpristay [2]

Answer: See below

Explanation:

Find the area of circle:

A = 3.14 x 5^2
A = 3.14 x 25
A = 78.5 cm^2

Find the area of rectangle:

A = 3 x 4
A = 12

Find area of shaded region:

A(shaded) = A(circle) - A(rectangle)
A = 78.5 - 12 = 66.5 cm^2

Normally a game console costs $525, but you only have $450. How much would the game console need to be discounted (as a percent)

klemol [59]

Answer: 14.29 or rounded up to 15%

Step-by-step explanation:

525 - 450 = 75

You need at least $75 off the price to have enough money.

75/525 = x/100

Solve for X

75 * 100 = 7500

7500/525 = 14.2857143

If answer should be a whole percentage you would need the discount to be 15% in order to not fall short on funds.

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations.

Aleksandr-060686 [28]

Answer:

$\huge \colorbox{red}{(x,y)=(-1,-3)}$

Step-by-step explanation:

multiply first equation by 4 and second by 3 respectively:

$\begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}$

combine the equations:

$\underline{ \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}} \\ \displaystyle16y = - 48$

divide both sides by -48:

$\displaystyle \: \frac{16y}{16} = \frac{ - 48}{16} \\ y = - 3$

substitute the value of y to the second equation

$\displaystyle \: 4x - 4. - 3 = 8$

simplify multiplication:

$\displaystyle \: 4x + 12 = 8$

cancel 12 from both sides:

$\displaystyle \: 4x = - 4$

divide both sides by 4

$\displaystyle \: \frac{4x}{4} = \frac{ - 4}{4} \\ x = - 1$

therefore our solution is

$\displaystyle (x,y)=(-1,-3)$
