A pool is surrounded by a rectangular fence with a
perimeter of 72 yards. If the length of the fence is 3
times the width, what is the length of the fence, in yards?
Answer:
width is 33
Step-by-step explanation:
width (b) =?
length(l)=3
perimeter (p)=?
now,
perimeter = 2(l+b)
or,72= 2(3+ b)
or,72/2= 3+b
or,36= 3+b
or,36-3= b
or,33= b
therefore width is 33
Lazare is dividing 52.8 ounces of cereal equally into 9 bags. Which is the best way to estimate the amount of cereal in each bag?
If I'm not mistaken it's 5.9
Estimate amount of cereal in one bag is 5.867 ounces.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Total quantity of cereal that Lazare has = 52.8 ounces.
And number of bags into which cereal equally divides = 9
To find the amount of cereal in each bag,
Use mathematical operations,
Since, total bags are 9 and amount of cereal is 52.8 ounces.
So, in one bag amount of cereal = 52.8 / 9 = 5.8666 = 5.867
In one bag there will be 5.867 ounces of cereal.

Which equation represents a line that passes through (0,–8) and (–5,–23)?
A) y = 4x – 8
B) y = –8x + 3
C) y = 5x – 8
D) y = 3x – 8
The equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.
Given that the line passes through (0,-8) and (-5,-23).
We are required to find the equation of the line that passes through (0,-8) and (-5,-23).
Equation is like a relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation, quadratic equation, cubic equation, and many more depending on the power of the variable.
The formula to form the equation from two points is as under:
[tex](y-y_{1}) =(y_{2} -y_{1} )/(x_{2} -x_{1} ) * (x-x_{1} )[/tex] in which [tex](x_{1} ,y_{1} ),(x_{2} ,y_{2} )[/tex] are the points.
(y+8)=(-23+8/-5-0)(x-0)
y+8=(-15/-5) x
y+8=3x
y=3x-8
Hence the equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.

write the slope intercept form of the equation of each line
Answer:
Y= - 1/5x-4
Step-by-step explanation:
slope intercept form: y=mx+b
Slope formula: rise/run
(5,-5) AND (0,-4)
-5+-4= -1
5+0= 5 AKA - [tex]\frac{1}{5}[/tex] or -1/5
The m in y=mx+b is the slope, the equation above is the sloe formula meaning -1/5 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -4. Thus, when plugging in the equation, y=-1/5x-4
What is the value of y? Show you’re work
Answer:
Y = 32
Step-by-step explanation:

So 180 - 52 = 128
Then 2y + 2y = 4y
So now 128/4 = 32

A picture of a rectangle is shown. The bottom of the rectangle is labeled 16 ft. The right side of the rectangle is labeled 8 ft. At the bottom left side of the rectangle there is a label that reads 2 ft. Inside the rectangle is a shaded region. The bottom of the region is labeled 8 ft and this side is perpendicular to the left side of the rectangle. The right side of the shaded region has a perpendicular line segment extending upward that is labeled 2 ft. At the top of this line segment is another line segment perpendicular to the right that reads 2 ft. At the end of this line segment is a perpendicular line segment extending upward that reads 1 ft. There is a line segment joining the end of this line segment with the top left corner of the rectangle.

Find the midpoint of AC is at -2 and C is at 3 on a number line
The value of midpoint of AC will be 0.5.
What is Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
Point A is at - 2 and C is at 3 on the number line.
Now,
Since, Point A is at - 2 and C is at 3 on the number line.
Hence, The midpoint of AC = (- 2 + 3 ) / 2
= 1/2
= 0.5
Thus, The midpoint of AC = 0.5
