Answer: 1) 9 days
2) a)37.5%
b)50%
c) 33.33%
Step-by-step explanation:
1) - Let's call:
x: number of days the company supposed to finish the order.
- You know that the company had to produce 40 items daily, but it produced 20 items more daily and finished the order 3 days ahead of time. Therefore, you can express this as following:
[tex]40x=(40+20)(x-3)\\40x=60(x-3)[/tex]
- Solve for [tex]x[/tex]:
[tex]40x=60x-180\\-20x=-180\\x=9[/tex]
(The answer is 9 days)
2) a) The percent that belongs to three people if eight eight people share equally in an inheritance, can be calculated as following:
[tex]\frac{3}{8}*100=37.5[/tex]%
b) The percent that belongs to three people if six people share equally in an inheritance (because two of the people are disinherited) can be calculated as following:
[tex]\frac{3}{6}*100=50[/tex]%
c) - The increase goes from 1/8 to 1/6, therefore, you must subtract them:
[tex]\frac{1}{6}-\frac{1}{8}=\frac{1}{24}=0.04167[/tex]
- Divide the result by 1/8 and multiply by 100 to obtain the percent:
[tex]\frac{0.04167}{\frac{1}{8}}*100=33.33[/tex]%

Ohn has taken out a loan for college. He started paying off the loan with a first payment of $100. Each month he pays, he wants to pay back 1.1 times the amount he paid the month before. Explain to John how to represent his first 20 payments in sequence notation. Then explain how to find the sum of his first 20 payments, using complete sentences.
Answer:
Ohn has paid $5730 in first 20 installments
Step-by-step explanation:
As per the question Ohn payed the first installment =$100
Next month Ohn payed the installment = 1.1×$100
Similarly subsequent installment =1.1×1.1×$100
So we can write first 20 installments as
⇒100+100×1.1+100×1.1²+100×1.1³.........+100×[tex]1.1^{20}[/tex]
And we know in geometric series
1+x²+x³+...........[tex]x^{20}[/tex] = (1-[tex]x^{n-1}[/tex])÷(1-x)
Therefore sum of first 20 installments will be
⇒100(1+1.1²+1.1³............[tex]1.1^{20}[/tex] =(1- [tex]1.1^{20}[/tex])÷(1-1.1)
= 100(1-6.73)÷(-.1)
=100×5.73÷.1
= $5730
So Ohn has paid $5730

Seattle, wa and san francisco, ca lie on the same longitudinal line. san francisco is at 38° latitude and seattle is at 47° latitude. if the earth is a sphere of radius 4000 miles, use arc length to find the distance between the cities. [use π = 3.14, and round to the nearest mile.]
Step 1.
Calculate measure of angle α:
[tex]47^o-38^o=9^o[/tex]
Step 2.
Calculate what fraction of the angle 360° is the angle α:
[tex]\dfrac{9^o}{360^o}=\dfrac{1}{40}[/tex]
Step 3.
Calculate the circumference of the Earth (circle):
[tex]C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi[/tex]
Step 4.
The length of arc is equal 1/40 of the circumference:
[tex]\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi[/tex]
[tex]\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi[/tex]
The distance between Seattle, WA, and San Francisco, CA, calculated using their latitudinal difference on a sphere with a radius of 4000 miles, is approximately 628 miles.
The question is asking for the distance between Seattle, WA and San Francisco, CA based on their respective latitudes and assuming they are on the same longitudinal line. To find the arc length and thus the distance between the two cities, you can use the formula for arc length on a sphere: [tex]\(Arc \ length = (\Delta Latitude \times \pi/180) \times \ Radius \ of\ Earth\)[/tex]. Here, [tex](\Delta Latitude\)[/tex] is the difference in latitude between the cities, which is [tex]\(47^\circ - 38^\circ = 9^\circ\)[/tex]. The radius of Earth is given as 4000 miles. Plugging these values into the formula, you get:
[tex]\(Arc \ length = (9 \times \pi/180) \times 4000\)[/tex]
[tex]\(Arc \ length = (9 \times 3.14/180) \times 4000\)\\\(Arc \ length = (0.157) \times 4000\)\\\(Arc \ length = 628 \ miles\)[/tex]
Therefore, the distance between Seattle and San Francisco, based on latitude and assuming they are directly north and south of each other, is approximately 628 miles.

Log 6 (1/36)
6 is the base. How to evaluate this?
We can write the argument of the logarithm as a power of 6:
[tex]\log_6\dfrac1{36}=\log_6\dfrac1{6^2}=\log_66^{-2}[/tex]
Then using the property that [tex]\log_ba^n=n\log_ba[/tex], we get
[tex]\log_6\dfrac1{36}=-2\log_66[/tex]
and since [tex]6=6^1[/tex], we have [tex]\log_66=1[/tex], so the value of this expression is simply -2.
The value of [tex]\(\log_6 \left(\frac{1}{36}\right)\)[/tex] is -2.
To evaluate [tex]\(\log_6 \left(\frac{1}{36}\right)\)[/tex], we can use properties of logarithms and exponents.
Let's set up the equation:
[tex]\[\log_6 \left(\frac{1}{36}\right) = x\][/tex]
This equation means:
[tex]\[6^x = \frac{1}{36}\][/tex]
We know that [tex]\(\frac{1}{36}\)[/tex] can be rewritten as [tex]\(6^{-2}\)[/tex] because:
[tex]\[36 = 6^2 \quad \text{so} \quad \frac{1}{36} = 6^{-2}\][/tex]
Thus, the equation [tex]\(6^x = \frac{1}{36}\)[/tex] becomes:
[tex]\[6^x = 6^{-2}\][/tex]
Since the bases are the same, we can equate the exponents:
x = -2
Therefore,
[tex]\[\log_6 \left(\frac{1}{36}\right) = -2\][/tex]
A dress is selling for $100 after a 20 percent discount. What was the original selling price?
SHOW ALL WORK
Answer:
$125
Step-by-step explanation:
original cost - discount = discounted price
discount = original cost * .2
original cost - original cost *.2 = 100
Factor out the original cost
original cost ( 1-.2) = 100
original cost *.8 = 100
Divide each side by .8
original cost *.8/.8 = 100/.8
original cost = 125

Step-by-step explanation:
Use the substitution method to solve the system of equations. Choose the correct ordered pair. y = 5x + 7 x = 8 A. (8, 47) B. (0, 7) C. (8, 15) D. (0, 8)
Assuming the system is composed of the equations y = 5x+7 and x = 8, then the answer is (8,47) which is choice A
To get this answer, we simply replace x in the first equation with 8, and then compute
y = 5x+7
y = 5*8+7 .... replace x with 8
y = 40+7
y = 47
So together x = 8 and y = 47 pair up to get us the solution (x,y) = (8,47)
After solving the equation by substitution method, the correct pair for x and y will be (8, 47). Hence, option A is correct.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given data provided by the question,
The equation is,
y = 5x + 7
Substitute x = 8 in the equation,
y = 5 (8) + 7
y = 47.
So, after substituting the x=8 the value obtained for y is 47.

A standard deck of playing cards has 52 cards: 13 spades, 13 clubs, 13 hearts, and 13 dimonds. What is the probabipity of drawing a spade from a standard 52 card deck, replacing it, then drawing another spade? Show your work or explain how you got your answer.
Final answer:
The probability of drawing a spade, putting it back, and then drawing another spade is 6.25%. This is calculated by multiplying the probability of drawing a spade twice with replacement.
Explanation:
The probability of drawing a spade from a standard deck of 52 cards is 13/52, since there are 13 spades in a deck. If you replace the card and reshuffle, the condition remains the same for the second draw.
Therefore, the probability of drawing another spade is also 13/52. To find the combined probability of two independent events, you multiply the probabilities of both events occurring.
Thus, the probability of drawing a spade, replacing it, and then drawing another spade is:
(13/52) × (13/52)
When you calculate that, you get:
= 169/2704
= 0.0625 or 6.25%
This means that there is a 6.25% chance of drawing a spade, replacing it, and drawing another spade on two consecutive draws from a standard deck of cards.
Nina buys a used car from Leon’s Used Cars and pays a $500 down payment and $299 per month for 48 months. The cash price is $12,500.00. How much interest does Nina pay if she chooses NOT to pay the cash price?
Answer:
The interest is $1852
Step-by-step explanation:
We are given
down payment = $500
$299 per month for 48 months
per month installment =$299
total months =48
total amount paid = (per month installment)*( total months)
now, we can plug values
total amount paid is
[tex]=299\times 48[/tex]
[tex]=14352[/tex]
total amount paid is $14352
The cash price is $12,500.00
so,
interest = (total amount paid)-( cash price)
so, interest is
[tex]=14352-12500[/tex]
[tex]=1852[/tex]
