Answers

Answer 1

Answer:

38.4895

Step-by-step explanation:

area of circle = pi * r^2

3.142 * 7^2 = area of the whole circle

as we only have 1/4 of the circle we divide our area by 4

(3.142 *7^2) / 4 = 38.4895

Answer 2

Answer:

38.4895

Step-by-step explanation:

basically you are finding a quarter of the area of the circle. So the formula is 1/4πr^2

so that's 3.142×7^2 and then divided by 4.

hope this helps

How many angles are alternate exterior angles with angle 5?

Answers

Answer:

The alternate exterior angles with angle 11 are angle 13 and angle 5.

Step-by-step explanation:

Two angles are called Alternate exterior angles if

1. They are on the exterior side of parallel lines and

2. Lie on the opposite sides of the transversal line.

It is given that

[tex]r||s[/tex] and [tex]t||u[/tex]

From the figure it is noticed that the angle 13 and angle 5 are on the exterior side of parallel lines and they lie on the opposite sides of the transversal line.

Therefore alternate exterior angles with angle 11 are angle 13 and angle 5.

Answers

The nature of solutions to equations can be finite, infinite or no solution. The solution to the system of equation 3x + 6 = -1-3 + 4x is 10

Solution to system of equations

The nature of solutions to equations can be finite, infinite or no solution.

Given the linear solution as shown:

3x + 6 = -1-3 + 4x

Collect the like terms

3x - 4x = -1 -3 -6

-x = -10

Multiply both sides by -1

-(-x) = -(-10)
x = 10

Hence the solution to the system of equation 3x + 6 = -1-3 + 4x is 10

Answer:

120 cars

Step-by-step explanation:

The given function is

[tex]C(x)=0.5x^2-120x+21,481[/tex]

and its parent function would be

[tex]f(x)=ax^2+bx+c[/tex]

So,

[tex]a=0.5[/tex]

[tex]b = -120[/tex]

and

[tex]c = 21,481[/tex]

The minimum cost would be found using:

[tex]x = -\frac{b}{2a}[/tex]

So just input a and b into the function:

[tex]x= -\frac{-120}{2(0.5)}[/tex]

[tex]x=-\frac{-120}{1}[/tex]

[tex]x = 120[/tex]

Therefore there must be 120 cars made to minimize the cost.

Gina is buying 24 oranges. Two stores offer the following deals:
Store A: 12 oranges for $6.48
Store B: 5 oranges for $2.65
Gina can buy oranges individually.
How much will Gina save if she buys 24 oranges at Store B?
Show your work.

Answers

Answer:

She saves 24 cents by buying 24 oranges at store B

Step-by-step explanation:

Price per orange A = 6.48 / 12 oranges = .54 per orange

.54 * 24 oranges = 12.96 for store A

Price per orange B = 2.65 / 5 = .53 per orange

.53 * 24 oranges = 12.72 for store B

12.96 - 12.72 = .24 dollars (24 cents)

What is coordinate geometry?

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Line segment FG begins at (-1, 5) and ends at (-1, -3). The segment is translated right 10 units and down 5 units to form line segment F'G'. Then the coordinate of F' and G' will be

F' = (-1 + 10, 5 - 5) = (9, 0)

G' = (-1 + 10, -3 - 5) = (9, -8)

Then the equation of the line passing through F' and G' will be

[tex]\rm y + 8 = \dfrac{-8-0}{9-9}(x - 9)\\\\y + 8 = 0[/tex]
