Steve went to Macy's to buy clothing, Steve got to the checkout, and he had
$96.30 worth of clothing in his arms. If he has a 30% of coupon, how much
would be his final bill?
Answer:
$67.41
Step-by-step explanation:
We want to find out how much 30% off of $96.30 is. To do that, we need to first multiply $96.30 to find out how much 30% would be. Don't forget to change 30% into its decimal form (30% - > .3).
96.30 x .3 = 28.89
This means that Steve got $28.89 dollars removed from his final bill. To find the actual final bill, subtract 28.89 from 96.30.
96.30 - 28.89 = $67.41

Square ABCD has a side length of 4 inches. The square is dilated by a scale factor of 4 to
form square A'B'C'D'. What is the side length of square A'B'C'D' ?
Answer:
The side of square A'B'C'D' is 16 inches
Step-by-step explanation:
Given
Length of Square ABCD = 4 inches
Dilated with a scale factor of 4
Required
Length of square A'B'C'D'
To dilate something means to enlarge or reduce the size of that thing, depending on the scale factor.
Consider the following conditions
When the scale factor is greater than 1, then the size of new shape will be bigger than the dilated shapeWhen the scale factor is equal to 1, the new shape will maintain the same size as the dilated shapeWhen the scale factor is less than 1 but greater than 0, the size of new shape will be smaller than that of the dilated shape.Having mentioned the conditions of dilation, Here, the "thing being dilated" is a square (ABCD) on a scale factor of 4.
The scale factor is greater than 1; so, the new shape (A'B'C'D) will be bigger than the previous shape (ABCD)
Now, how is the new size calculated?
The new size is calculated by multiplying the length of the previous shape by its scale factor;
In other words,
New Length = Old Length * Scale Factor
Where
Old Length = Length of ABCD = 4 inches
Scale Factor = 4
By Substitution,
New Length = 4 inches * 4
New Length = 16 inches
Hence, the side of square A'B'C'D' is 16 inches

The cylinder below has a volume of 2,512 cubic cm and a height of 8 centimeters. What is the diameter of the cylinder? Use 3.14 for pi.
Answer:
Radius=10cm
Diameter=20cm
Step-by-step explanation:
The Diameter of the cylinder is 20 centimeters.
It is given that the cylinder has a volume of 2,512 cubic cm and a height of 8 centimeters.
It is required to find the diameter of the cylinder.
What is a volume?It is defined as a three-dimensional space enclosed by an object or thing.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2h[/tex]
Where r is the radius of the cylinder and h is the height of the cylinder.
We have V = 2512 cubic centimeters and
h = 8 centimeters
[tex]\rm 2512 =3.14\times r^2\times8[/tex]
[tex]\rm \frac{2512}{3.14\times8} = r^2[/tex]
[tex]\rm r^2 =100[/tex]
r = 10 centimeters
Diameter = 2r = 2×10 ⇒ 20 centimeters.
Thus, the Diameter of the cylinder is 20 centimeters.

Carbon-14 is a radioactive isotope of carbon that is used to date fossils. There are about 1.5
atoms of cafbon-14 for every trillion atoms of carbon in the atmosphere, known as 1.5 ppt
(parts per trillion). Carbon in a living organism has the same concentration as carbon-14. When
an organism dies, the carbon-14 content decays at a rate of 11.4% per millennium (1000 years).
Write an equation for carbon-14 concentration (in ppt) as a function of time (in millennia) and
determine how old a fossil must be that has a measured concentration of 0.3 ppt.
Answer:
Function: A=1.5(1+0.114)^1000
Step-by-step explanation:
1.5 is the initial amount and 0.114 in the rate and the 1000 is the time
In carbon dating, the Carbon-14 concentration decays exponentially, and can be described by a formula involving its initial concentration and decay rate. To find a fossil's age with a concentration of 0.3 ppt, we use this decay formula, solve for t (time in millennia), and calculate the fossil's age.
Explanation:To determine the Carbon-14 concentration as a function of time and the age of a fossil with a concentration of 0.3 ppt, we will use the formula of exponential decay based on the half-life concept in carbon dating.
The formula for the carbon-14 concentration as a function of time (t, in millennia) is:
C(t) = C_0 × (1 - 0.114)^t
Where:
C(t) is the Carbon-14 concentration at time t,C_0 is the initial Carbon-14 concentration (1.5 ppt), and0.114 is the rate of decay per millennium (11.4%).To find the age of a fossil with a measured concentration of 0.3 ppt, we solve for t in the above equation with C(t) set to 0.3 ppt:
0.3 = 1.5 × (1 - 0.114)^t
Dividing both sides by 1.5 and taking the natural logarithm:
t = ln(0.3/1.5) / ln(1 - 0.114)
Solving this gives us the age of the fossil in millennia.

profit maximizing Q: 35profit maximizing P: $13maximum profit: $227.5Step-by-step explanation:
Labeling the columns of the spreadsheet A--F, and the rows 1--7, we want to find the values as follows.
a) The relationship between quantity, price, and revenue is ...
total revenue = quantity × price
price = (total revenue)/quantity
Then ...
B3 = 375/25 = 15 (as shown)C4 = 30×14 = 420 (as shown)__
b) The relationship between total cost and marginal cost is ...
mc2 = (tc2 -tc1)/(q2 -q1)
tc2 = (mc2)(q2 -q1) +tc1
Then ...
D6 = 9(40 -35) +227.5 = 272.5E4 = (192.5 -162.5)/(30 -25) = 6__
c) Marginal revenue is figured the same way as marginal cost.
mr2 = (r2 -r1)/(q2 -q1)
Then ...
F2 = (320 -0)/(20 -0) = 16F6 = (480 -455)/(40 -35) = 5__
d) The quantity maximizing profit will be the quantity such that marginal revenue is equal to marginal cost. That is, marginal profit is zero. That quantity is 35, where both marginal cost and marginal revenue are 7.
__
e) The price at a quantity of 35 is 13. This value is read from the given table.
__
f) The maximum profit is the difference between revenue and cost at the profit-maximizing quantity:
maximum profit = 455 -227.5 = 227.5
The question refers to Total Cost (TC) and Marginal Cost (MC) in economics; where TC is the sum of all production costs and MC is the cost of producing one more unit of a good. To fill the table, calculate the difference in total cost for each increase in produced units, as this difference reflects the MC.
Explanation:The question is referring to the concepts of Total Cost (TC) and Marginal Cost (MC) in economics. Total Cost is the complete expenditure made by a firm in the production process, including both fixed and variable costs. Marginal Cost, on the other hand, is the cost of producing one additional unit of a good. In the case of the Choco Lovers firm, it represents the cost of producing an extra box of chocolates.
To fill in the blanks in the table, the differences in total cost for each increase in the quantity of chocolate gift boxes produced should be calculated. This is because the MC at each level of output is the addition to total cost when one more box is produced. So, if total cost rises by $5 when output increases from 10 to 11 boxes, the MC of the 11th box is $5.

A trapezoid has an area of 30m^2. if all of its side lengths are tripled, what will its new area be
Answer:
270
Step-by-step explanation:
Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine
For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270
Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.
10*3=30 so we can say for this answer, the base is 3, and the height is 10.
10 tripled is 30, and 3 tripled is 9. 30*9=270
So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

The basic model of a particular car (2WD) with a power sunroof costs $29,115. When equipped with four-wheel drive (4WD) and a sunroof, the vehicle's price rose to
$31,105. The cost of the basic model with 4WD was $30,205. Find the basic price, the cost of 4wd and the cost of a sunroof
Answer:
Sunflower=$900
4WD=$1090
Step-by-step explanation:
Wheareas 2WD costs $29,115 but when converted to 4WD it costs $30,205 then it means the cost of 4WD will be $30205-29115=$1090
The total cost of converting 2WD to 4WD with inclusion of sunroof is $31,105
Therefore, the total cost of 4WD and sunroof will be $31105-$29115=$1990
To get the amount for sunroof, we deduct the total cost that includes 4WD and sunroof from $1090
Cost will be $1990-$1090=$900
