The perimeter of a rectangular parking lot is 286 m.
If the width of the parking lot is 56 m, what is its length?
Answers
Answer:
87 metres
Step-by-step explanation:
The perimeter of the parking lot is 286 metres, while it is 56m in width.
The formula for the perimeter of a rectangle is:
[tex]P = 2(l+w)\\P = 2l + 2w[/tex]
with l and w as the the length and width, respectively.
The problem has two givens, perimeter and width.
[tex]286 = 2l + 2w\\286 = 2l + 2(56)\\286 - 112 = 2l\\174 = 2l\\\frac{174}{2} = l\\l=87[/tex]
The length of the lot is 87 meters.

A milk truck has a diameter of 10 and feet and a height of 50 feet. How much milk can the truck hold?
Answers
Answer:
The mentioned milk truck can hold:
3927 ft^3 of milk.Step-by-step explanation:
As you can see, the question is asking about the volume of the milk truck, to obtain the volume of a cylinder, first we must to find the area of the surface side, in this case is a circle, to find the area of a circle when we have the diameter is:
Area of a circle = [tex]\pi *\frac{\ D^{2} }{4}[/tex]Where D is the diameter given (10 feet), now we replace and operate:
Area of a circle = [tex]\pi *\frac{\ (10 ft)^{2} }{4}[/tex]Area of a circle = [tex]\pi *\frac{\ 100 ft^{2} }{4}[/tex]Area of a circle = [tex]\pi *25 ft^{2}[/tex]Area of a circle = 78.54 ft^2 approximatelyNow, with the data of the area, we can calculate the volume with the formula below:
Volume of a cylinder = Area of the circle * heightVolume of a cylinder = 78.54 ft^2 * 50 ftVolume of a cylinder = 3927 ft^3With the calculations, we can see the milk truck can hold 3927 cubic feet of milk with those dimensions.

Bella says the lateral area of a square pyramid is 1,224 inches squared. Do you agree or disagree with Bella? Use numbers and words to support your answer. If you disagree with Ella, find the correct answer. The height is 25in and the bases are 18in. (2 bases)
Answers
Answer:
[tex]900\ \text{in}^2[/tex] Disagree
Step-by-step explanation:
[tex]b[/tex] = Length of side of base = 18 in
[tex]h[/tex] = Height of each triangle = 25 in
Lateral area of the pyramid is
[tex]A=\dfrac{4hb}{2}=2hb[/tex]
[tex]\Rightarrow A=2\times 25\times 18[/tex]
[tex]\Rightarrow A=900\ \text{in}^2[/tex]
The actual lateral area of the pyramid is [tex]900\ \text{in}^2[/tex] so, I disagree with Bella.

Three yrs hence, a men will be three time his brother age and the sum of present age is 18 find their present age
Answers
Answer:
Step-by-step explanation:
Let the age of a man = x
Age of his brother = y
Three yrs hence, a man will be three time his brother age
This is written as:
x + 3 = 3(y + 3)
x + 3 = 3y + 9 .... Equation 1
The sum of present age is 18
= x + y = 18
x = 18 - y
We substitute 18 - y for x in Equation 1
find their present age
18 - y + 3 = 3y + 9
Collect like terms
21 - 9 = 3y + y
12 = 4y
y = 12/4
y = 3 years
x = 18 - y
x = 18 - 3
x = 15 years
Carmela randomly selected 85 stamps from a stamp collection. Eleven of these were commemorative stamps.
What is the interval estimate for the proportion of commemorative stamps in the entire collection if the sampling method had a margin of error of ±0.035 ?
(0.075, 0.145)
(0.285, 0.355)
(0.082, 0.089)
(0.095, 0.165)
Answers
Answer:
(0.095, 0.165)
Step-by-step explanation:
Confidence interval :
Phat ± margin of error
Margin of Error = 0.035
Phat = x / n
Phat = 11 / 85 = 0.1294117
Hence,
Phat ± 0.035
Lower boundary = 0.1294117 - 0.035 = 0.0944
Upper boundary = 0.1294117 + 0.035 = 0.1644
(0.0944, 0.1644)
Answer:
The answer is (0.095, 0.165)

C. Distribute 2 to all necessary terms
The function in standard form is f(x)=
Answers
Answer:
y = 2x^2 + 12x + 14
Step-by-step explanation:
Write this equation in standard form. Start by performing the exponentiation:
y = 2(x^2 + 6x + 9) - 4
Perform the indicated multiplication:
y = 2x^2 + 12x + 18 - 4, or
y = 2x^2 + 12x + 14: This is the quadratic function in standard form.
The value of the quadratic function in standard form is,
⇒ f (x) = 2x² + 12x + 14
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The function is,
⇒ f (x) = 2 (x + 3)² - 4
Now, We get;
The value of the quadratic function in standard form is,
⇒ f (x) = 2 (x + 3)² - 4
⇒ f (x) = 2 (x² + 9 + 6x) - 4
⇒ f (x) = 2x² + 18 + 12x - 4
⇒ f (x) = 2x² + 12x + 14
Thus, The value of the quadratic function in standard form is,
⇒ f (x) = 2x² + 12x + 14

Answers
Answer:
first option
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = - 2 and (a, b ) = (4, - 4 ) , then
y - (- 4) = - 2(x - 4) , that is
y + 4 = - 2(x - 4)
