Answer:
7 days
Step-by-step explanation:
(a) Filling in the given information will result in two equations in the two unknowns. Dividing one by the other will tell you the value of b.
n=2
1.8 = A₀·b²
n=3
2.4 = A₀·b³
Dividing the second equation by the first gives ...
2.4/1.8 = (A₀·b³)/(A₀·b²) = b
4/3 = b
__
(b) Substituting this into the first equation, we can find A₀.
1.8 = A₀·(4/3)²
1.8(9/16) = A₀ = 1.0125
A₀ is the value of A when n=0. It is the area of the patch at the beginning of observation, before any days passed.
__
(c) The area will be 7 cm when ...
1.0125·(4/3)^n = 7
(4/3)^n = 7/1.0125 . . . . . . . . . . . . divide by A₀
n·log(4/3) = log(7/1.0125) . . . . . . take logarithms
n = log(7/1.0125)/log(4/3) ≈ 6.72092
It will take about 7 days for the area of the patch to exceed 7 cm.

An animal shelter has fixed weekly expenses of $750. Each animal in the shelter costs an additional $6 a week. a. During the summer months, the weekly expenses are at least $1170. Write and solve an inequality that represents the number of animals at the shelter for expenses to be at least $1170 a week.
Answers
Answer:
1170≥6x+750 x=70
Step-by-step explanation:
We can put these numbers into a slope equation, y=mx+b, the fixed weekly expense ($750) represents b. And the $6 per animal is the slope or m. So our equation become y=6x+750. Now the weekly expense is $1170 and will represent the y in the equaion, 1170=6x+750. First subract 750 from both sides, 420=6x, divide by 6 and get that there was 70 animals in the shelter that week.
The number of animals the shelter needs to house in order for expenses to be at least $1170 per week is calculated as 1170≥6x+750 x=70
Explain about the Inequality?In mathematics, an inequality is a link that compares two numbers or other mathematical expressions unfairly. Size comparisons between two numbers are commonly made on the number line.
In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to one another.
These figures can be entered into the slope equation y=mx+b, where the fixed weekly expense ($750) stands in for b. Additionally, the slope or m costs $6 per animal. We now have the equation y=6x+750. The current weekly expense of $1170 will serve as the y-coordinate in the equation, 1170=6x+750. First, divide 750 from both sides by 420 to obtain 6x, then divide that result by 6 to get the number of animals in the shelter that week 70.

Use the inequality 12>6(12x+2). Complete parts a and b.
Answers
Answer/ Step-by-step explanation:
12>6(12x+2)
Divide both sides by 6. Since 6 is positive, the inequality direction remains the same.
12/6 >12x+2
Divide 12 by 6 to get 2.
2>12x+2
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
12x+2<2
Subtract 2 from both sides.
12x<2−2
Subtract 2 from 2 to get 0.
12x<0
Product of two numbers is <0 if one is >0 and the other is <0. Since 12>0, x must be <0.
x<0

someone please help me.. i can’t figure out what to do. but i need this explained step by step so i know what to do next time.
Answers
Answer:
Step-by-step explanation:
½(x-2) = 8 + 5x
Multiply both sides by 2
2⋅½(x-2) = 2(8 + 5x)
1(x-2) = 2(8 + 5x)
Apply the distributive rule
x - 2 = 16 + 10x
Subtract x from both sides
-2 = 16 + 9x
Subtract 16 from both sides
-18 = 9x
Divide both sides by the coefficient of x
-18 ÷ 9 = 9x ÷ 9
-2 = x

Answer:
See below for the journals.
Step-by-step explanation:
Note: The instructions of the question are as follows:
Instructions
(a) Prepare the journal entries to record these transactions on the books of Bramble Co. using a periodic inventory system.
(b) Assume that Bramble Co. paid the balance due to Tamarisk Company on May 4 instead of April 15. Prepare the journal entry to record this payment.
The journal entries will look as follows:
(a) Prepare the journal entries to record these transactions on the books of Bramble Co. using a periodic inventory system.
Date Details Debit ($) Credit ($)
April 5 Inventory - merchandise 41,700
Accounts Payable 41,700
(To record the purchase of merchandise inventory on account from Tamarisk.)
April 6 Inventory 790
Cash credit 790
(To record the payment of freight costs on merchandise.)
April 7 Equipment 27,100
Accounts Payable 27,100
(To record the purchase equipment on account.)
April 8 Accounts Payable 5,700
Inventory 5,700
(To record the return of damaged merchandise to Tamarisk.)
April 15 Accounts Payable (w.1.) 36,000
Cash (w.3.) 35,280
Inventory (discount) (w.2.) 720
(To record the payment of the amount due to Tamarisk Company in full.)
(b) Assume that Bramble Co. paid the balance due to Tamarisk Company on May 4 instead of April 15. Prepare the journal entry to record this payment.
Date Details Debit ($) Credit ($)
May 04 Accounts payable (w.1.) 36,000
Cash 36,000
(To record the payment of the amount due to Tamarisk Company in full.)
Working:
For the payment made on April 15, this implies the payment was made within 10 days and that Bramble Co. will enjoy 2% discount. Therefore, we have:
w.1. Accounts payable = Beginning inventory – Returns = $41,700 - $5,700 = $36,000
w.2. Discount = w.1. * 2% = $36,000 * 2% = $720
w.3. Cash = w.1. – w.2. = $36,000 - $720 = $35,280

Arianna put $250 in a savings account with an interest rate of 3%. If Arianna does not deposit or withdraw any money, what is the amount of interest that Arianna will earn at the end of six MONTHS?
Answers
Answer:
She will earn 485.13075 in interest.
Step-by-step explanation:
Assuming the interest rate is monthly and it is simple interest, the equation is Total = amount * (1 + rate) * time
Fill that out and solve the equation
T = 2500 * (1.03) * 6
T = 2500 * (1.1940523)
T = 2985.13075
To find the interest subtract T by 2500
2985.13075 - 2500 = 485.13075
