What is the rate of change (Slope) of the cost with respect to the number of miles for the Yellow Cab Company?
Answer:
The slope would be 2
Step-by-step explanation:
All you do is pick two order pairs: (2,6) and (4,10), then you do y1 - y2, so 10-6 to get 4 then do x1 - x2, so 4 - 2 which is 2, then you divide 4 by 2 to get 2.

In ΔHIJ, h = 40 cm, ∠J=20° and ∠H=93°. Find the length of j, to the nearest centimeter.
Given:
In ΔHIJ, h = 40 cm, ∠J=20° and ∠H=93°.
To find:
The length of j, to the nearest centimeter.
Solution:
According to Law of sine,
[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
In ΔHIJ, using law of sine, we get
[tex]\dfrac{j}{\sin J}=\dfrac{h}{\sin H}[/tex]
[tex]\dfrac{j}{\sin (20^\circ)}=\dfrac{40}{\sin (93^\circ)}}[/tex]
[tex]j=\dfrac{40\times \sin (20^\circ)}{\sin (93^\circ)}}[/tex]
On further simplification, we get
[tex]j=\dfrac{40\times 0.34202}{0.99863}[/tex]
[tex]j=\dfrac{13.6808}{0.99863}[/tex]
[tex]j=13.69958[/tex]
Approximate the value to the nearest centimeter.
[tex]j\approx 14[/tex]
Therefore, the length of j is 14 cm.

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric fence. With 1500 m of wire at your disposal, what is the largest area you can enclose, and what are its dimensions
Step-by-step explanation:
Let x be the length and y be the width of the rectangular plot.
The plot is bounded on one side by a river and on the other three sides by a single-strand electric fence. It means,
x+2y = 1500
x = 1500 - 2y ....(1)
We know that the area of a rectangular plot is given by :
A = xy ....(2)
Put the value of x from equation (1) in (2)
[tex]A=(1500-2y)y\\\\A=1500y-2y^2[/tex] .....(3)
For largest area, differentiate above area equation wrt y.
[tex]\dfrac{dA}{dy}=\dfrac{d}{dy}(1500y-2y^2)\\\\=1500-4y\\\\\text{Put}\ \dfrac{dA}{dy}=0\\\\1500-4y=0\\\\y=\dfrac{1500}{4}\\\\=375[/tex]
Put the value of y in equation (1).
x = 1500-2(375)
= 750 m
Put the value of y in equation (3).
[tex]A =1500(375)-2(375)^2\\A=281250\ m^2[/tex]
Hence, the largest area is 281250 m² and its dimensions are 750 m and 375 m.
evaluate - 31 - 8 + 31
Answer:
-8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
Step 1: Define
-31 - 8 + 31
Step 2: Evaluate
Subtract: -39 + 31Add: -8The difference between two numbers is 8. Twice the number is 4 more than the larger number. What is the smaller number?
Answer:
If the two numbers are x and y, then:
x + y = 8
18 - 2x = 4y - 2.
When we subtract y from both sides in our first equation we get:
x = 8 - y, so:
18 - 2(8 - y) = 4y - 2
18 - 16 + 2y = 4y - 2
2 + 2y = 4y - 2
2y = 4
y = 2
Since x + y = 8, and y = 2, x = 6, and since 6 > 2, the larger number is 6.

If a tree casts a 45-foot shadow at the same time that a 6-foot tall man casts a 7.5-foot shadow, find the height of the tree.
1 ft
36 ft
45 ft
56.25 ft
Answer:
36 feet
Step-by-step explanation:
I believe this is the answer
1/3(9x +45) - x = 6x +4
1/3(9x+45)-x=6x+4
we can move the numbers on the right and the x's on the left
9x/3+45/3-x=6x+4
3x-x-6x=4-15
-4x=-11
x=11/4
