Answer:

6 {x}^{2}  = 726 \\  \frac{6 {x}^{2} }{6}  =  \frac{726}{6}  \\  {x}^{2}  = 121 \\ x =  \sqrt{121}  \\ x = 11

PLEASE HELP! Daniela has a rectangular yard with a pool in the shape of a semicircle. How many square feet of grass does Daniela
GalinKa [24]

Answer:

Part 1) Area of rectangle 3,600\ ft^{2}

Part 2) Area of semicircle 1,413\ ft^{2}

Par 3) Total area of grass 2,187\ ft^{2}

Step-by-step explanation:

we know that

The total area of grass is equal to the area of rectangle minus the area of semicircle

step 1

Find the area of rectangle

The area of rectangle is equal to

A=45*80=3,600\ ft^{2}

step 2

Find the area of semicircle

The area of semicircle is equal to

A=\frac{1}{2}\pi r^{2}

we have

r=60/2=30\ ft -----> the radius is half the diameter

substitute

A=\frac{1}{2}(3.14)(30)^{2}

A=1,413\ ft^{2}

step 3

Find the total area of grass

3,600\ ft^{2}-1,413\ ft^{2}=2,187\ ft^{2}

Which gives the best estimate and the exact product of (5.9)(8.28)? A: estimate: 40; exact product: 48.852
Evgesh-ka [11]
I think B gives the best estimate and exact product because

1). 5.9 x 8.28 is very similar to 6 x 8 which equals 48.

and 

2. 5.9 x 8.28 = 48.852.

Hopefully that made sense. :)

Brand X costs $1.65 for 11 ounces. Brand Y costs 2 cents more per ounce. What is the cost of 15 ounces of brand Y?
34kurt

Answer:

$2.25

Step-by-step explanation:

You can find the answer by setting up a simple equation.

Brand X is 1.65 for 11 ounces

we can find the cost of one ounce of Brand X by using division

1.65/11

.15

this means that for every ounce of Brand X, it costs 15 cents

Since brand Y costs two cents more per ounce that would make it be 17 cents per ounce

now all you need to do is multiply and solve.

.15 * 15 = $2.25
