The dimensions of a rectangular building used to store tools for electrical lineman has a length of 12x+24 feet and the width of 20x-10 feet.
1.Write the expression that represents the area of the building, in terms of x.
2. Write the expression that represents the perimeter of the building, in terms of x.
3. If the perimeter is going to be 220 feet, what are the dimensions of the building.
Answers
Answer:
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet
Step-by-step explanation:
It is given that:
Length of building = 12x + 24
Width of building = 20x - 10
Area = Length * Width
Area = (12x + 24) * (20x - 10)
Area = 12x(20x - 10) +24(20x-10)
Area = [tex]240x^2-120x+480x-240[/tex]
Area = [tex]240x^2+360x-240 = 2x^2+3x-2[/tex]
Perimeter = 2 (Length + Width )
Perimeter = 2 (12x + 24 + 20x - 10 ) = 2 (32x +14 )
Perimeter = 64x + 28
Putting Perimeter = 220
220 = 64x + 28
64x = 220 - 28
64x = 192
Dividing both sides by 64
x = 3
Length = 12(3) + 24 = 36 + 24 = 60 feet
Width = 20(3) - 10 = 60 - 10 = 50 feet
Therefore,
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet
Timothy bought groceries two days during the week: • Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday • Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday Which equation models the relationship between the cost of groceries after taxes, and the cost of groceries before taxes?
Answers
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.
We would solve this using direct proportion.
y = kx.
12.15 = 11.25k
k = 12.15 / 11.25
k = 1.08
Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.
y = kx.
59.13 = 54.75k
k = 59.13 / 54.75
k = 1.08
The equation that models the relationship will be:
y = 1.08x

what are the first 5 terms of 30-n^2
Answers
Answer:
29, 26, 21, 14, 5
Step-by-step explanation:
To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the n th term formula.
30 - 1² = 30 - 1 = 29
30 - 2² = 30 - 4 = 26
30 - 3² = 30 - 9 = 21
30 - 4² = 30 - 16 = 14
30 - 5² = 30 - 25 = 5
The first 5 terms are 29, 26, 21, 14, 5

2) 150 in^2
Step-by-step explanation:
For the first question we list the numbers according to their sign(start from negative)
For the second question we multiply height with width to find the area of the rectangle.
1. order the intergers {-10, -25, 25, 10, -50} from least to greatest. 2.what is the area of the rectangle?Answer:-
1.

negetive numbers are smaller than positive number,
According to the question,
order the intergers {-10, -25, 25, 10, -50} from least to greatest is:-

Answer:

Step-by-step explanation:
When a number increased by 4
Let that number = x
x + 4
is doubled...
2(x + 4)
the result is the same
=
when the number is increased by 20
x + 20
Find the number
2 (x + 4) = x + 20
2x + 8 = x + 20
2x - x = 20 - 8
x = 12
What does X equal? X equals 12
Check:
Insert the x = 12 into the equation;
2 (x + 4) = x + 20
2 (12 + 4) = 12 + 20
2 (16) = 12 + 20

2)Same for this. 4^2+5^2= 9^2
3)a^2+b^2 = ab^2 because since a and b are different letters/variables you cannot combine them therefore it is just ab.
4) (-1)^2 = 1 because -1 multiply by -1 again you would get positive 1. Next you do 1+0^2 = 1. Because 0^2 is just 0 because 0times 0 =0 so 1+0 = 1

Answer:
v = $312.5
Step-by-step explanation:
Let
Value of the gem stone = v
Weight of the gemstone = w
v = k * w²
Where,
k = constant of proportionality
w = 4 carat
v = $200
v = k * w²
200 = k * 4²
200 = k * 16
200 = 16k
k = 200/16
k = 12.5
Find v when w = 5 carat
v = k * w²
= 12.5 * 5²
= 12.5 * 25
= 312.5
v = $312.5
