Answer:

The perimeter of the shape is 32.5

Step-by-step explanation:

Since the dashed line is not a perimeter,

we add the circumference of the circle plus the 3 sides of the rectangle

The circumference is of the half circle with its diameter being the opposite side of the rectangle

The opposite side is the length 10

So the radius is half of this which is 10/2 = 5

The circumference of the semicircle is thus;

pi * r = 22/7 * 5 = 15.71

full circle is 2 * pi * r

semi is half of full so we divide formula by 2

So let’s add up

15.71 + 10 + 3.4 + 3.4 = 32.51

Answer:

-9

Step-by-step explanation:

180=85+44+60+(x)-9

Answer:

A. -9

Step-by-step explanation:

A triangle equals 180 degrees so:

60 + 85 + x + 44 = 180

add like terms

x + 189 = 180

subtract 189 from both sides

x = -9

Answer:

slope = [tex]\frac{9}{4}[/tex]

Step-by-step explanation:

Equation to find slope: [tex]\frac{y1-y2}{x1-x2}[/tex]            (-3, 4) (-7, -5)

[tex]\frac{4+5}{-3+7}[/tex] = [tex]\frac{9}{4}[/tex]

Answer:

Step-by-step explanation:

we have the diameter =60 cm, the radius is 60/2=30 cm

A circle is 3.14*r^2=2827 cm^2

Answer: C. 2827 cm2

Step-by-step explanation:

The area of a circle is calculated by pir^2; r = the radius

In the diagram, the diameter is provided. The radius is half of the diameter. 60/2 = 30, so the radius is 30 cm.

Plug these values into the formula

A = 3.14*30^2

A = 2827.43, which would round to 2827 cm2

Answer:

−12x + 4

Step-by-step explanation:

Distribute:

= ( − 3 ) ( 4x ) + ( − 3 ) ( − 2 ) + − 2

= − 12x + 6 + − 2

Combine Like Terms:

= − 12x + 6 + − 2

= ( − 12x ) + ( 6 + − 2 )

= − 12x+4

Answer:

Mark's shadow would be 3 feet.

Step-by-step explanation:

If a building is 50 feet tall and casts a 25 foot shadow, then the shadow of an object is 1/2 the length of the actual object.

This can be supported by the division problem:

50 ÷ 2 = 25

If Mark is 6 feet tall, then we need to divide 6 by 2 in order to find the length of the shadow.

6 ÷ 2 = 3

Therefore, Mark's shadow would be 3 feet.

Hope this helps! :D

Answer: |10 - (-8)|  

The absolute value is 18

Step-by-step explanation:

The distance between two numbers is a subtraction equation.

10 - (-8)  Subtracting a negative is like adding a positive

10 + 8 = 18

If you look at it as the first negative sign means -1 multiplied by the next negative number, "Remember that a negative times a negative is a positive!"

Answer:

|-10 - (-8)|

Answer:

LOL i don't even know

Step-by-step explanation:

Answer:

Part 1 and 2: P represents principle, or the original cost of the mortgage. i represents the annualinterest rate (r/n), and t represents time. When you change the time it affects monthlypayments because theres either more or less time to pay off the mortgage. Having a longertime to pay off means you'll have lower monthly payments. When the interest rateincreases, the monthly payment increases. This is because the higher the interest rate, themore interest you're paying. Changing the principle means you either have more or lessmoney to pay off.P2: Increasing i will increase the total cost since more interest will be charged. Increasingtime means there's more periods for interest to gather so the total cost will increase.Shortening the time will decrease the total cost because there will be less time for interestto accumulate.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

we can see that the line goes thru the point (-1,2) and (4,-2) now to find slope we just find change in y over change in x

more visually:

(y1-y2)/(x1-x2)

so for the point (-1,2) let’s say

-1 = x1

and

2 = y1

and for the point (4,-2) let’s say

4 = x2

and

-2 = y2

to find slope we plug in the values to our slope equation and we get this:

(2-(-2))/( -1-4)

(2+2)/-5

4/-5

so slope is -4/5

because to get from (-1,2) to (-4,-2) you have to move down 4 and to the right 5

Answer:

Domain → [-5, ∞)

Range → [-2, ∞)

Step-by-step explanation:

Domain:

Domain of a function on from its graph is represented by the set of x-values (Input values).

Range:

Range of a function is a set of y-values (output values).

From the graph attached,

Graph starts from x = -5 and tends towards the infinity, so the domain will be,

Domain → [-5, ∞)

Similarly, y-values vary from y = -2 to y = ∞

Therefore, Range → [-2, ∞)

Given the graph of the function:

Domain is: [-5, ∞)

Range is: [-2, ∞)

The domain of a function are all the values of x that are plotted on the x-axis, while the corresponding y-values are the range of the function.

Thus:

From the given graph representing a function:

Domain of the function is between -5 to infinity.

Range of the function is between -2 to infinity.

Therefore, given the graph of the function:

Domain is: [-5, ∞)

Range is: [-2, ∞)
