Answer:
Total amount paid for the Car=$24,832
Finance Charge=$2,382
Step-by-step explanation:
Down payment on the Car=$2800
Number of Monthly Installments=36
Amount Paid Per Installment=$612
Total Monthly Installment Paid=36*$612=$22032
Therefore, the Total Amount Paid for the Car=Down Payment+Total Installmental Payment=2800+22032=$24,832
Next, we determine the finance charge.
Finance Charge=Total Amount Paid for the Car - Delivered Price of the Car
=24832-22450
=$2,382
Therefore:
Total amount paid for the Car=$24,832
Finance Charge=$2,382
A soup can, shaped like a cylinder, has a diameter of 3.5 inches and a height of 5 inches. Each serving of soup is 15 cubic inches. If a can of soup this size costs $1.99, what is the cost of each serving of soup? Round to the nearest cent.
Answer:
The answer to your question is Cost of a serving = $0.62
Step-by-step explanation:
Data
diameter = 3.5 in
height = 5 in
each serving = 15 in³
Cost of the can = $1.99
Process
1.- Calculate the volume of the can
Volume = πr²h
-Substitution
Volume = (3.14)(3.5/2)²(5)
-Simplification
Volume = (3.14)(3.062)(5)
-Result
Volume = 48.08 in³
2.- Use proportions and cross multiplication to find the cost of a serving.
48.08 in³ ---------------- $1.99
15 in³ ---------------- x
x = (15 x 1.99)/48.08
x = 29.85/48.08
x = $0.62
In a lab, 180 cells are present at the beginning of an experiment. During the first 9 hours, the number of cells increased by 8% each hour. Write an exponential model giving the number of cells y present t hours after starting the experiment. Estimate the time when the number of cells is 360.
Answer:
The answer is 9 hours
Step-by-step explanation:
From the initial population of 180 cells, the number grows by 8% every hour for the first 9 hours.
This represents a increased population of 108% the previous population.
108% = 108/100 = 1.08
So the new population after n hours is
180 x 1.08^n
When population is 360
360 = 180 x 1.08^n
1.08^n = 2
Take log of both sides
n x Log1.08 = Log 2
n = Log 2/Log 1.08
n = 9
A zoo has some new exhibits.
In a survey, 2400 zoo attendants are asked to choose their favorite.
The results are shown in the following table.
(a) find the percentage for each type of animal.
Answer:
Elephant 14%
Panda 18%
Tiger 29%
Bonobo 39%
Step-by-step explanation:
Divide each number by 2400 then multiply the answer by 100.
The percentage of elephants, pandas, tigers, and bonobos are 14%, 18%, 29%, and 39% respectively.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
The zoo has some new exhibits.
In a survey, 2400 zoo attendants are asked to choose their favorite.
From the table:
The total number of animals = 336 + 432 + 696 + 936 = 2400
Percentage of Elephant = (336/2400)x100 = 14%
Percentage of Panda = (432/2400)x100 = 18%
Percentage of Tiger = (696/2400)x100 = 29%
Percentage of Bonobo = (936/2400)x100 = 39%
Thus, the percentage of elephants, pandas, tigers, and bonobos are 14%, 18%, 29%, and 39% respectively.

the wheels of a bicycle are 0.6 m in diameter. If I go around the bike block, each wheel will perform 346 full turns. What distance, to the tenth of a meter ready, that represents it
Answer:
The distance that represents it is 651.9 m.
Step-by-step explanation:
In order to calculate the distance that the wheel travelled we need to find the length of the circumference of the wheel. This is given by the following formula:
length = 2*pi*r = pi*d
Since the diameter of the wheel is 0.6 m we can find the length of the wheel that is:
length = 3.14*0.6 = 1.884 m
The wheel made 346 full turns, that means that the total distance is the number of turns multiplied by the length of the wheel.
distance = 346*1.884 = 651.9 m
The distance that represents it is 651.9 m.

A 12 sided die with sides labeled 1 through 12 will be rolled once each number greater than 10?
Answer:
See the explaination
Step-by-step explanation:
Total No. of rolling each side of the 12-sided die= 12 x 12= 144 outcomes
No. of outcomes equals 10 are: (1, 9), (9, 1), (2, 8), (8, 2), (3, 7), (7, 3), (4, 6), (6, 4), (5, 5) = 9 outcomes.
No. of outcomes of rolling a No. >10: 144–9 = 135 outcomes.
Probability, Pr, of rolling a No. >10= 135/144
Pr (No. >10) = 0.9375 (to 4 dec. pl.)

Dave determines the meal he ordered at the restaurant contains 22% of his daily sodium intake. If the meal contains 260 mg of sodium, how many mg of sodium are in Dave's daily diet? Round your answer to the nearest whole mg
Answer:
1182 mg to the nearest mg.
Step-by-step explanation:
22% is equivalent to 260 mg sodium, so
100% is equivalent to 260 * (100/22)
= 1181.82 mg.
what is percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Examples of percentages are:
10% is equal to 1/10 fraction
20% is equivalent to ⅕ fraction
25% is equivalent to ¼ fraction
50% is equivalent to ½ fraction
75% is equivalent to ¾ fraction
90% is equivalent to 9/10 fraction
Given,
Dave determines the meal he ordered at the restaurant contains 22% of his daily sodium intake
Meal contains 260 mg of sodium
22% is equivalent to 260 mg sodium, so
100% is equivalent to 260 x ([tex]\frac{100}{22}[/tex])
= 1181.82 mg.
22% is equivalent to 260 mg sodium, so
100% is equivalent to 260 * (100/22)
= 1181.82 mg.

Answer:
(x+3)(2x+7)
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
(2x2 + 13x) + 21
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 2x2+13x+21
The first term is, 2x2 its coefficient is 2 .
The middle term is, +13x its coefficient is 13 .
The last term, "the constant", is +21
Step-1 : Multiply the coefficient of the first term by the constant 2 • 21 = 42
Step-2 : Find two factors of 42 whose sum equals the coefficient of the middle term, which is 13 .
-42 + -1 = -43
-21 + -2 = -23
-14 + -3 = -17
-7 + -6 = -13
-6 + -7 = -13
-3 + -14 = -17
-2 + -21 = -23
-1 + -42 = -43
1 + 42 = 43
2 + 21 = 23
3 + 14 = 17
6 + 7 = 13 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 6 and 7
2x2 + 6x + 7x + 21
Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (x+3)
Add up the last 2 terms, pulling out common factors :
7 • (x+3)
Step-5 : Add up the four terms of step 4 :
(2x+7) • (x+3)
Which is the desired factorization
Final result :
(x + 3) • (2x + 7)

a campground owner had 150 meters of fencing to enclose a rectangualr field adjacent to a river and also bisect that field into two equal halves. No fencing required with river. what are the dimesions of the largest area that can be enclosed
Answer:
Dimension of the Rectangle : 2W - 150 by W
Step-by-step explanation:
Given
Land Size = 150 metres
This land size represents the perimeter of the land
Let P = Perimeter
So, P = 150 m
To bisect the field into two equal halves means to divide length or width of the field into two equal halves
Let L = Length of the field
Let W = Width of the field
Assuming the length of the field is to be bisected., then the campground owner is left with 0.5L (i,e half of the length)
Perimeter of a rectangle is calculated by: 2(Length + Width)
P = 2(L + W) by substitution, becomes
150 = 2(0.5L + W) ----open bracket
150 = L + 2W ---- Male L the subject the formula
L = 2W - 150
The dimension of the largest area that can be enclosed id given by (L,W)
By substitution; the expression becomes
Dimension of the Rectangle : 2W - 150 by W
Robert recently discovered a forgotten student loan bill. The amount due after 10 years is
now $10,819.33. He found some old statements and determined that after 7 years the bill
was $8831.80 and after 5 years he owed $7714.03.
1. How much did Robert borrow initially?
2. Robert is planning to pay the loan in full next year. How much will he owe then?
3. What is the interest rate on Robert’s loan?
Answer:
1.Robert borrowed $ 5,500.00
2.The amount Robert would repay next year is $ 11,576.69
3.The interest rate on the loan is 7%
Step-by-step explanation:
The interest on the loan can be computed using compound annual growth
rate
CAGR=(EB/BB)^1/n-1
EB is ending balance of $8831.80 in year7
BB is the balance of year 5 $7714.03
n=7-5=2
CAGR=(8831.8/7714.03)^(1/2)-1
CAGR==1.070000427-1
CAGR=0.070000427
CAGR=7%
The amount borrowed can be computed using the PV formula
At year 0 year 5 amount of $7714.03 is the future value
rate of interest is 7%
number of years is 5
PV=$7714.03*(1+7%)^-5
PV=$ 5,500.00
The amount Robert would pay next year is :
FV=$10,819.338(1+7%)^1
FV=$ 11,576.69
