Find the area to the nearest square foot of the shaded region below, consisting of a square with a circle cut out of it. Use 3.1
NeTakaya

Answer:

22 square feet

Step-by-step explanation:

Area of shaded region = Area of square - Area of circle. The diameter of the circle is also the length of the side of the square as the circumference of the circle is on the circumference of the square.

Area of circle = 3.14 × r × r

r = 10 ÷ 2

= 5

Area of circle = 3.14 × 5 × 5

= 78.5

Area of square = length × length

Area of square = 10 × 10

= 100

Area of shaded region = Square - Circle

= 100 - 78.5

= 21.5

= 22 (to the nearest square foot)

I hope this helps :)

Jayden sells snow cones for $3.75 each. He started the day with a total of 300 snow cones to sell. If he made a total of $843.75
Leni [432]

Number of cone left is 75 cone

<u>Given that;</u>

Cost of each cone = $3.75 each

Starting number of cone = 300

Total amount earn = $843.75

<u>Find:</u>

Number of cone left

<u>Computation:</u>

Number of cone sale = Total amount earn / Cost of each cone

Number of cone sale = 843.75 / 3.75

Number of cone sale = 225 cone

Number of cone left = Starting number of cone - Number of cone sale

Number of cone left = 300 - 225

Number of cone left = 75 cone

Kelsey can buy 2 pounds of apples for 7$. Write an equation to represent the cost, c, for a, pounds of apples.
zmey [24]

\huge\boxed{c=3.5a}

First, we need to find how much a single pound of apples costs.

Do this by dividing.

\frac{\$7}{2\ \text{lbs.}}\div\frac{2}{2}=\frac{\$(7\div 2)}{(2\div 2)\ \text{lbs.}} = \frac{\boxed{\$3.50}}{1\ \text{lb.}}

Now, write an equation.

\large\boxed{c=3.5a}

This represents that the cost equals 3.5 times the number of apples.

erica [24]

Answer:

x=6, x= -5

Step-by-step explanation:

Factor the equation

x^2 - x - 30 = 0 ----> (x-6)(x+5)=0

Next find the solution by setting those in the paranthesis equal to zero.

x-6=0 ----> x= 6

x+5=0 ----> x= -5
