Step-by-step explanation:
Pi x radius² = area of a circle
Sixteen inches is the diameter and since the radius is half the diameter, this must mean the diameter is eight inches.
Therefore, if we substitute this into the equation, pi x eight² is the area.
This could be written as sixty four pi or 201.06192983 in²
This means the closest answer is C
Answer:
C
Step-by-step explanation:
Area= π(r squared)
Area= π(8 squared)
Area= 200.96 in squared

What is the equation of the line that passes through the point (-4, 2) and has a
slope of 1/4?
Answers
Answer:
y = (1/4)x + 3
Step-by-step explanation:
I have put my answer in slope-intercept form as that is usually the most common. Inputing the slope as "m" into the equation "y=mx+b" and substituting the x and y coordinates given to find b gives the equation "2=(1/4)(-4)+b" By solving this we get "b=3" to finish the equation.
Answer:
y=1/4x+3
Step-by-step explanation:
y-2=1/4(x-(-4))
y-2=1/4(x+4)
y-2=1/4x+1
y=1/4x+1+2
y=1/4x+3
Can someone please help me with math
Answers
Answer:
B
Step-by-step explanation:
they want us to find the equation in slope intercept form
which is y= mx + b
where m = slope and b = y intercept
the slope is change in y over change in x
as y goes up 1 x goes up 1 so the slope is 1 or m=1
the y intercept is at point (0,1)
so the y intercept is 1
now we add it all together and get that the equation Is
y=x+1

What is the y-intercept of the line y+8= -2(x-2.5)
Answers
Answer:
The y intercept is -3 or (0, -3)
Step-by-step explanation:
y+8= -2(x-2.5)
y + 8 = -2x + 5
y = -2x -3
y= mx + b
b = y-intercept
Answer:
y-intercept = -3
Step-by-step explanation:
y + 8= -2(x - 2.5)
y + 8= -2x + 5
subtract 8
y = -2x -3
y-intercept = -3

4x + 5y = 9
4x - 2y = 2
Answers
Answer:
x = 1 and y = 1
Step-by-step explanation:
Let's solve your system by substitution.
4x + 5y = 9 ; 4x − 2y = 2
- Solve 4x + 5y = 9 for x:
4x + 5y = 9
4x + 5y + − 5y = 9 + − 5y (Add -5y to both sides)
4x = − 5y + 9
[tex]\frac{4}{x} = \frac{- 5y + 9}{4}[/tex]
[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]
Then Substitute [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex] for x in 4x - 2y = 2
4x − 2y = 2
4([tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]) − 2y = 2
− 7y + 9 = 2 (Simplify both sides of the equation)
− 7y + 9 + − 9 = 2 + − 9 (Add -9 to both sides)
− 7y = − 7
[tex]\frac{- 7y}{- 7} = \frac{- 7}{- 7}[/tex] (Divide both sides by -7)
y = 1
Substitute 1 for y in x = [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]
[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]
[tex]x = \frac{- 5}{4} (1) + \frac{9}{4}[/tex]
x = 1
So, x = 1 and y = 1

Step-by-step explanation:
From the question, we are informed that Ed's birthday is less than 16 days
away and that Ann writes the inequality
d< 16, where d equals the number
of days, to represent this.
The inequality d < 16 is correct as it explains that the number of days left is less than 16.
Answer:
Ann is correct because d is less than 16.
Step-by-step explanation:
Ed's Birthday is *less than 16* days away so d<16

*6. Five brothers each bought two hot dogs & a bag of chips. If the chips

A. $1.35 per hot dog
B. $1.45 per hot dog
C. $1.55 per hot dog
D. $1.65 per hot dog
Answers
Take the amount of the bag of chips which is 1.25 and multiply it by 5 because that’s how many people there are and they each bought one bag
1.25 x 5= 6.25
Next you want to subtract that amount from the total so we can just have the amount of money spent on hot dogs
22.27-6.25=16.50
Then you want to divide 16.50 by 5 because they all bought the same amount of hot dogs and this will get us to the amount of to hot dogs
16.50/5=3.30
Finally you want to divide 3.30 by 2 which will get us the price for 1 hot dog
3.30/2=1.65
There you go!!

What is the area of the shaded quadrilateral? (see attachment)
Answers
Answer:
B. 36 [tex]cm^{2}[/tex]
Step-by-step explanation:
The shaded quadrilateral has a shape of a trapezium.
Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the side length parallel to the base, b is the base and h is the height.
The height of the figure = 11 - (4 + 1)
= 11 - 5
= 6
The height of the figure is 6 cm.
The length of its base = 11 - (1 + 2)
= 11 - 3
= 8
The length of its base is 8 cm.
The length of the side parallel to base = 11 - (4 + 3)
= 11 - 7
= 4
The parallel side length to base is 4 cm.
Area of quadrilateral = [tex]\frac{1}{2}[/tex](a + b)h
= [tex]\frac{1}{2}[/tex](4 + 8)6
= 12 x 3
= 36
Area of quadrilateral = 36 [tex]cm^{2}[/tex]

Answer:
Y = 5 - 2/x
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
You want to isolate x so first, you have to multiply the whole equation by 1/4 so it will look like 1/4(2y+4/x=10). Simplify this to get 1/2y+x=5/2. You want to isolate x, so you have to subtract 1/2 from each side, this will make the equation x=5/2-1/2. Simplify this to get x=4/2 which can also be simplified to x=2. Therefore, the answer is x=2

Answer:
[tex]x=3[/tex]
Step-by-step explanation:
Normally, linear equations would be written in slope-intercept form, [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis). However, linear equations for horizontal or vertical lines are organized differently.
Here, we're given a vertical line. Vertical lines are written like [tex]x=d[/tex], where [tex]d[/tex] is the x-intercept, or the value of x when the line crosses the x-axis.
From the graph, we can tell that the x-intercept is 3. Therefore, our equation would be [tex]x=3[/tex].
