2. Two rectangular fields with identical shapes and areas are to be fenced side by side. The total area enclosed is 8mi^2 and the perimeter for all the fencing is 16 miles. Find the possible dimensions of one of the fields (2 possible answers).
Step-by-step explanation:
Let length is x and breadth is y.
The formula for the area and the perimeter of a rectangle is given by :
A = xy
P = 2(x+y)
Here, A = 8 mi² and P = 16 miles
Putting all the values,
xy = 8
y=8/x ......(1)
2(x+y) = 16
x+y = 8 .....(2)
Put equation (2) in equation (1) as follows :
[tex]x+\dfrac{8}{x}=8\\\\x^2+8=8x\\\\x^2-8x+8=0[/tex]
When we solve, we get :
x = 6.82 miles, 1.17 miles
Put the value of x in equation (1)
When x = 6.82 miles,
y = 8/6.82
y = 1.17 miles
When x = 1.17 miles,
y = 8/1.17
y = 6.82 miles
Hence, the dimension of the field is 6.82 miles and 1.17 miles.

The state fair charges $14 for admission. Each ride costs $6.
What is the function that relates the amount spent, S, to the number of rides, r?
Answer:
S = 6r + 14
Step-by-step explanation:
14 is the intercept(which wont increase), and 6 is the slope which will increase with every ride

Answer:
1. y=-4/3x+9
2. y=-4x+6
Step-by-step explanation:
1.y=-4/3x+b
put in 3,5 into equation
5=-4/3(3)+b
5=-4+b
9=b
so y=-4/3x+9
2. y=4x+b
2=4(-1) +b
2=-4+b
6=b
y=-4x+6
g(x)= 3x-5
h(x)=2/2x+3
write h(g(x)) as an expression terms of x
Answer: h(g(x))= 2/6x-7
Step-by-step explanation:
1.h(g(x))= 2/(g(x))+3
2.g(x)= 3x-5
h(g(x))= 2/2(3x-5)+3
=2/6x-10+3
=2/6x-7
Jason used 0.5 cup of kernels to make 16 cups of popcorn how many cups of popcorn would he make if he used 0.75 cup of kernels.
A. 32
B. 28
C. 24
D. 20
PLEASE HELP ME IM DAILING MATH
Answer:
Option C: 24 is the correct answer.
Step-by-step explanation:
Given that:
Jason used 0.5 cup of kernels to make 16 cups of popcorn
Ratio of cup of kernel to cups of popcorn = 0.5 : 16
Let,
x be the cups of popcorn made from 0.75 cups of kernel
Ratio of cups of kernel to cups of popcorn = 0.75 : x
This is a direct proportion as the cups of kernel is increasing.
0.5 : 16 :: 0.75 : x
Product of mean = Product of extreme
16*0.75 = 0.5x
12=0.5x
0.5x=12
Dividing both sides by 0.5
[tex]\frac{0.5x}{0.5}=\frac{12}{0.5}\\x=24[/tex]
Jason can make 24 cups of popcorn from 0.75 cups of kernel.
Hence,
Option C: 24 is the correct answer.

Answer:
5a. ΔGKM ~ ΔSPM by SAS
b. ΔABC is not similar to ΔDEF
6. The missing side is 2[tex]\sqrt{11}[/tex]
Step-by-step explanation:
5a. Yes, the triangles are similar.
<KMG ≅ <PMS (vertically opposite angles)
ΔGKM ~ ΔSPM by SAS
Ratio: GM:SM OR KM:PM
3:6 OR 2:4
1:2 OR 1:2
Ratio: 1:2
b. No, the triangles are not similar
ΔABC is not similar to ΔDEF
Ratio: AC:DF OR AB:DE
4:6 OR 2:4.5
1:1.5 ≠ 1:2.25
Ratio: not similar
6. let the missing side of the triangle be represented by x. Since the triangle is a right angled triangle, then applying the Pythagoras theorem we have;
[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/12/^{2}[/tex] = [tex]x^{2}[/tex] + [tex]/10/^{2}[/tex]
144 = [tex]x^{2}[/tex] + 100
[tex]x^{2}[/tex] = 144 - 100
= 44
x = [tex]\sqrt{44}[/tex]
= [tex]\sqrt{4 *11}[/tex]
= 2[tex]\sqrt{11}[/tex]
x = 2[tex]\sqrt{11}[/tex]
The missing side is 2[tex]\sqrt{11}[/tex].
A submarine hovers at 66 and two-thirds yards below sea level. If it ascends 24 and StartFraction 1 over 8 EndFraction yards and then descends 78 and three-fourths yards, what is the submarine's new position, in yards, with respect to sea level?
Answer:
- 121 7/24
Step-by-step explanation:
Initial Position = 66 2/3 below sea level
Ascent = 24 1/8
Descent = 78 3/4
New position of submarine :
Since initial. Position is below sea level, we finite with a negative sign :
-66 2/3 = - 200 /3
Ascent is positive ; 24 1/8 = 193 / 8
-200 /3 + 193 / 8
(-1600 + 579) / 24
= - 1021 / 24
Descent = 78 3/4 (negative) downward
78 3/4 = - 315/ 4
-1021 / 24 - 315/4
(-1021 - 1890) / 24
= - 2911 / 24
= - 121 7/24
121 7/24 below sea level
The change in the value of stock is represented by the rational number -5.90. Describe, in words, what this means.
Answer:
DEFINITION of Value Change
Value change is an adjustment made to a stock's price to reflect the number of outstanding stock shares issued and currently held by investors. A value change allows the group of stocks to be equally weighted and, therefore, more easily evaluated. Since the number of shares held by investors changes daily, this number can be updated daily to reflect the changes.

A wire is attached to a 425-foot tower that is perpendicular to the ground. The wire makes an angle of 26.5o to the ground. what is the length of the wire in feet
Answer
952.49feet
Step-by-step explanation:
This set up will be a right angled triangle
Height = opposite side = 425foot
Length of wire = hypotenuse= x
Angle of elevation= 26.5°
Using the SOH identity
Sin 26.5 = opp/hyp
Sin26.5 = 425/x
x = 425/sin26.5
x =425/0.4462
x = 952.49feet
Hence the length of the wire is 952.49feet

An airplane is flying from nyc to la. The distance it travels in miles,d, is related to the to the time in seconds, t, by the equation d=0.15t
Answer:
It will cover 4.5 miles in 30 seconds.
Step-by-step explanation:
An airplane is flying from nyc to la.
The distance it travels in miles,d, is related to the to the time in seconds, t, by the equation :
d=0.15t ...(1)
Let us assume we need to find the distance at t = 30 s.
Put t = 30 s in equation (1).
d=0.15 × 30
d = 4.5 miles
Hence, it will cover 4.5 miles in 30 seconds.

Using mental math, the approximate tip to leave for a bill of $81.79, if you tip 15% would be _____.. a. $8.20 b. $10.30 c. $12.30 d. $16.40 Please select the best answer from the choices provided A B C D
Step-by-step explanation:
The approximate tip is - 12.30$
Because bill is 81.79$
and tip - 15%
therefore bill amount divided by 15/100
==> 81.79* 15% is 12.30$

Answer:
1. W = 50 ft
2. L = 110 m
3. L = 61 m
Step-by-step explanation:
Area of a Rectangle
Given a rectangle of width W and length L, its area is calculated by the formula:
A = W.L
We are given three rectangle-shaped figures and are required to find different measures as explained below.
1. Length L=94 ft, Area = 4,700 square ft
We'll find the width by solving for W:
[tex]\displaystyle W = \frac{A}{L}[/tex]
[tex]\displaystyle W = \frac{4,700}{94}[/tex]
W = 50 ft
2. A=8,250 square m, W=75 m
We'll find the length by solving for L:
[tex]\displaystyle L = \frac{A}{W}[/tex]
[tex]\displaystyle L = \frac{8,250}{75}[/tex]
L = 110 m
3. A=1,586 square m, W=26 m
We'll find the length by solving for L:
[tex]\displaystyle L = \frac{A}{W}[/tex]
[tex]\displaystyle L = \frac{1,586}{26}[/tex]
L = 61 m
