Answer:
Step-by-step explanation:
Given that:
Initial psi yesterday = 40 psi
psi today = 38 psi
If trend continues and tire loses the same percentage of air. How much air will be left in tire at the end of the week
1 week ( 7days)
Total loss after 7 days = (amount lost per day * number of days)
Total psi lost per day= [(40 - 38) = 2
% psi lost = (2/40) * 100
= 5%
Applying the exponential loss functin:
A = I ( 1 - r)^t
t = 7days ; r = 5% = 0.05 ; A = amount left ; I = Initial amount
A = 40(1 - 0.05)^7
A = 40(0.95)^7
A = 40 * 0.69833729609375
A = 27.933
A = 27.9 psi

A function that changes in the same way all the time is?
Answer:
A function that changes the same way can be a linear function.
y = a*x + b.
Where the rate of change (this is, how much changes y when x increases or decreases) is defined by the coefficient a, that is constant.
for example, suppose that when x = x0, we have y = y0
y0 = a*x0 + b.
Now x0 increases by one unit, to (x0 + 1)
y = a*(x0 + 1) + b = (a*x0 + b) + a = y0 + a.
Then if x increases (or decreases) 1 unit, y increases (or decreases) a units.
Now, we can define the rate of change of a function as it's derivate with respect to some variable.
In this case, if we derive with respect to x, we have:
y' = a
Then the rate of change is constant.

Question 5
Dwight owns 1600 acres of farmland. He wants to split the PLEASE HELP TIMED TEST !!
land into fourths and sell off each of the parcele, which expression shows the amount of acres that each parcel will contain? Select ALL that apply
1600 =
1600-4
1600
B
С
D
16.4
E
1600-
1600+
F
Answer:
Options (B) and (C)
Step-by-step explanation:
Farmland owned by Dwight = 1600 acres
He wants to divide his farmland into four equal parts.
So the area of each part of the land will be = [tex]\frac{\text{Area of the farmland}}{\text{Number of parts of the farmland}}[/tex] = [tex]\frac{1600}{4}[/tex]
This expression can be written in different ways,
[tex]\frac{1600}{4}=[/tex] 1600 ÷ 4
[tex]=1600\times \frac{1}{4}[/tex]
Therefore, Options (B) and (C) will be the correct options.

Round 8.1785 to the nearest hundredth
Answer:
I believe its 8.18 hope I helped. =)
Answer:
8.1785 to the nearest hundredth is 8.18.
Step-by-step explanation:
1. I left 8. and change the .1785 because 17 is the hundredths place. Next I took the .1785 and rounded it to .18 because the 85 is above 50.
2. I put the two numbers together (8. & .18) and I got 8.18.
I hope this helps:)

Find the distance between the points (-9,2) and (-1,4). Round to the nearest tenth if necessary.
Answer:
The answer to the nearest tenth is 8.2
Step-by-step explanation:
In order to find the distance between any two points, you must use the distance formula. when you plug in the points into the formula you end up with 8.246, rounded to the nearest tenth would be 8.2. I hope this helps!

What is the scale factor
Answer:
1/3
Step-by-step explanation:
33/11=3
so its 1/3 of it
Answer:
1/3
Step-by-step explanation:
If you divide one of the sides in figure A by 3, then you will get the corresponding side for figure B.
So if I divide the uppermost side, which is 33units by 3, I will get the uppermost side in figure B, which is 11units.
Since dividing b 3 is like multiplying by 1/3 then the scale factor is 1/3

What is 2/3 divided by 4/5???????
Answer:
10/12 also 5/6
Step-by-step explanation:
Answer:
10/12 or the simplified version 5/6
Step-by-step explanation:
you have to multiply 2/3 by the reciprocal of 4/5 which is 5/4
so you write down 2/3 times 5/4 (just multiply across so it's 2x5 over 3x4)
2x5=10 and 3x4=12
10 is the numerator and 12 is the denominator
simplify if the problem calls for it by dividing the top and bottom numbers by 2
10x + 1 + 12x - 5 = 180 Find x
Answer:
x = 92/11
Step-by-step explanation:
10x + 1 + 12x - 5 = 180
*group the like terms*
(10x + 12x) + (1-5) = 180
*simplify*
22x - 4 = 180
*add four on both sides to cancel out -4*
+4. +4
*simplify*
22x = 184
*divide both sides by 22 to cancel out the quantity and solve for x*
÷22 ÷22
*simplify*

Infinitely many because if you subtract 7x from both sides, you get 4 = 4, which is true at all times no matter what x is.
