A rectangular enclosure at the zoo is 35 feet long by 18 feet wide. The zoo wants to double the area of the enclosure by adding the same distance x to the length and width. Write and solve an equation to find the value of x. What are the dimensions of the enclosure?
Answer:
the value of x is 10
Step-by-step explanation:
The new length is 35+10=45 and the new width is 18+10=28.
What is Area of Rectangle?Area of rectangle is length times of breadth.
Given that enclosure at the zoo is 35 feet long by 18 feet wide. It means length is 35 feet and width is 18 feet.
Area of Rectangle=Length × Width
=35×18
=630
The zoo wants to double the area of the enclosure by adding the same distance x to the length and width.
(35+x)×(18+x)=1260
630+35x+18x+x2=1260
x2+53x+630-1260=0
x2+53x-630
Now use the quadratic formula we get
x=10.
The new length is 35+10=45
The new width is 18+10=28.
Hence the new length is 35+10=45 and the new width is 18+10=28.

Husky Shipping Company charges a flat rate of $150 plus $0.60 per pound to transport freight in the metro area. This cost is represented by the function below where w is the weight of the freight in pounds and c(w) is the cost given the weight of the freight. How much does Ferdinand Freight Company charge to transport freight weighing 1,500 pounds?
Answer:
Total cost = $1,050
Total cost = Fixed charges + Variable charges[Total weight]
Step-by-step explanation:
Given:
Fixed charges = $150
Variable charges = $0.60
Total weight = 1,500 pound
Find:
Total cost
Computation:
Total cost = Fixed charges + Variable charges[Total weight]
Total cost = 150 + 0.60[1,500]
Total cost = 150 + 900
Total cost = $1,050

a) Work out the rate of change during the first 4 seconds.
b) Work out the rate of change between 8 seconds and 12 seconds.
Answer:
a. 37.5
b. 25
Step-by-step explanation:
a. Rate of change the first 4 seconds can be calculated using the points (0, 0) and (4, 150):
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{150 - 0}{4 - 0} = \frac{150}{4} = 37.5 [/tex]
b. Rate of change between 8 seconds and 12 seconds using the points (8, 150) and (12, 250):
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{250 - 150}{12 - 8} = \frac{100}{4} = 25 [/tex]

Sara walks at a constant speed. She walked 1 mile in 15 minutes. Which equation represents the amount of time in minutes, t, that it took for her to walk a distance of d miles? *
t = (1/15)d
t = 15d
t = d + 15
t = d - 15
Answer:
t=15d
Step-by-step explanation:
The problem is asking for total time, so we can set everything equal to t. If it takes 15 minutes for 1 mile and she's walking at a constant speed, we know that the solution is t=15d.
We can plug in one mile to verify this answer.
t=15(1)
t=15

George hiked from the top of a hill to the valley floor. The elevation at the top of the hill is 127 feet above sea level. The valley floor is 52 feet below sea level. George stopped at a rest stop that is at an elevation exactly halfway between the top of the hill and the valley floor. What is the elevation, in feet, of the rest stop? Show your work
Answer:
The elevation of the rest stop is 37.5 feet above sea level.
Step-by-step explanation:
Given that the elevation at the top of the hill is 127 feet above sea level and The valley floor is 52 feet below sea level.
So, the total length from the top of the hill to the valley floor
[tex]l= 127+52 = 179[/tex] feet
So, length of halfway [tex]= l/2=179/2=89.5[/tex] feet ...(i)
Assuming that the stop for rest, the halfway between the top of the hill and the valley floor, is at x feet above sea level.
So, the length between the stop position and the valley floor [tex]= 52 +x[/tex] feet.
As the stop position is at half-way, so by using equation (i), we have,
[tex]52 + x = 89.5 \\\\\Rightarrow x =89.5-52 \\\\[/tex]
[tex]\Rightarrow x=37.5[/tex] feet
Hence, the elevation of the rest stop is 37.5 feet above sea level.

What is the elevation in feet of the road 5 miles from the starting point?
A. 1000
B. 1250
C. 750
D. 1500
Answer:
I think the answer is 1500
Step-by-step explanation:
Elevation of the road at 5 miles from the starting point is 1250 ft.
Similarity of triangles: If two triangles are similar, their corresponding sides will be proportional.
Given in the question,
Two triangles formed by a road are ΔADE and ΔABC (As shown in the figure attached).
Since, ∠A ≅ ∠A (Reflexive property)
∠AED ≅ ∠ACB (right angles)
ΔADE ~ ΔABC (By A-A property of similarity)
In these similar triangles, corresponding sides will be proportional.
[tex]\frac{AB}{BC}=\frac{AD}{DE}[/tex]
[tex]\frac{8}{2000}=\frac{5}{DE}[/tex]
[tex]DE=\frac{5\times 2000}{8}[/tex]
[tex]=1250[/tex] miles
Therefore, elevation of the road at 5 miles from the starting point will be 1250 ft.
Option (B) will be the answer.

Select the table that represents a linear function. (Graph them if necessary.)
Answer:
table B represents the linear equation which is:
[tex]y=-3x+11[/tex]
The graph of the linear function is also attached below.
Step-by-step explanation:
Given the table B values
x y
0 11
1 8
2 5
3 2
As the equation for the linear function
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
As the y-intercept can be obtained by setting x=0
From the table, it is clear that when the value of x=0, then the value of
y=11.
so (0, 11) is the y-intercept.
Also taking two points (0, 11) and (1, 8) to find the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:11\right),\:\left(x_2,\:y_2\right)=\left(1,\:8\right)[/tex]
[tex]m=\frac{8-11}{1-0}[/tex]
[tex]m=-3[/tex]
so substituting the value m=-3 and the point (1, 8) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-8=-3\left(x-1\right)[/tex]
[tex]y-8=-3x+3[/tex]
[tex]y=-3x+3+8[/tex]
[tex]y=-3x+11[/tex]
comparing the equation with the slope-intercept form of linear equation
[tex]y=mx+b[/tex]
[tex]y=-3x+11[/tex]
here
m=slope=-3b=y-intercept=11Therefore, table B represents the linear equation which is:
[tex]y=-3x+11[/tex]
The graph of the linear function is also attached below.
