Auntie Sammy buys a hand bag. There was a discount
of 20%.
If Auntie Sammy paid $245, what was the original price?
Answer:
Step-by-step explanation:
I think the original proce would be $265
1. Subtract the percentage discount from 100
100 - 20= 80
2. Multiply the final price($245) by 100
245 × 100= 24,500
3. Divide the answer in step 2 by the answer in Step 1
24,500 ÷ 80= $306.25
answer is $306.25
How to check to ensure your answer is correct:
1. Multiply the "answer" by the discount price divided by 100. This will give the discount percentage in dollars.
$306.25 × 0.2( which is 20÷100)= $61.25(discount in dollars)
2. Subtract the discount in dollars from the "answer"
$306.25 - $61.25= $245(final price is the same as in the problem so it is correct)
OR
1. Multiply the original price by the number you get from step 1 in your problem divided by 100
$306.25 × 0.8(80 from the very first step divided by 100)= $245(the final price is the same given in the question)

1,863
Step-by-step explanation:
If cos A= 1/8 With A in QIV, find sec A/2
Show work
Recall the half-angle identity,
cos²(x/2) = (1 + cos(x))/2
The angle A terminates in the fourth quadrant, so 270° < A < 360°. Then the corresponding half-angle terminates in the second quadrant, since 135° < A/2 < 180°, so cos(A/2) < 0. This means
cos(A/2) = - √((1 + cos(A))/2) = -3/4
so that
sec(A/2) = 1/cos(A/2) = -4/3.
The figure below shows ∠ABC formed by the hands of the clock at 4 o’clock. What is the measure of ∠ABC?
Answer:
120°
Step-by-step explanation:
30° x 4 = 120°
Full turn is 360
half is 180
and 180 degree = 6 parts

Your company paid a dividend of $2.00 last year. The growth rate is expected to be 4 percent for 1 year, 5 percent the next year, then 6 percent for the following year, and then the growth rate is expected to be a constant 7 percent thereafter. The required rate of return on equity (ks) is 10 percent. What is the current stock price?
Answer: Calculation of the dividends:- Year 1 = 2 * (1.04) = $ 2.08 Year 2 = 2.08 * (1.05) = $ 2.184 Year 3 = $ 2.184 * (1.06) = $ 2.31504 Year 4 = $ 2.31

Step-by-step explanation:
Alicia sews costumes for schools
She takes 86 minutes to sew one costume
Therefore the time taken to sew 16 costumes can be calculated as follows
86 mins= 1 costume
x= 16 costume
Cross multiply
x= 86×16
= 1376 minutes

Answer:
-368.8 ft
Step-by-step explanation:
distance = velocity × time
Here, we'll use a negative for speed downward, and positive for speed upward.
elevation = (-4.5 ft/s)(98 s) +(1.9 ft/s)(38 s) = -441 ft +72.2 ft
elevation = -368.8 ft

Dolores deposited $2500 into a savings account which interest compounded monthly at a rate of 2.12%
How much interest will they earn after 8 years? Round to the nearest dollar
Help pleaseeeeeeeeeee
Answer:
2961.63
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.12/100
r = 0.0212 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 2,500.00(1 + 0.0212/12)(12)(8)
A = 2,500.00(1 + 0.001766667)(96)
A = $2,961.63
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $2,500.00 at a rate of 2.12% per year compounded 12 times per year over 8 years is $2,961.63.

A website administrator is considering using one of the two models above to predict the total number of purchases, P, made x weeks after the website's advertisin(g campaign begins. How many more purchases are predicted by the exponential model than by the linear model 5 weeks after the advertising campaign begins?
P = 2000x
P= 500(2^x)
A. 6000
B. 8000
C. 10,000
D. 16,000
9514 1404 393
Answer:
A. 6000
Step-by-step explanation:
Use x=5 and evaluate each model.
Linear model
P = 2000(5) = 10,000
Exponential model
P = 500(2^5) = 500(32) = 16,000
The difference in the predicted value is ...
16,000 -10,000 = 6,000 . . . more are predicted by the exponential model

|x- 13| - 5= -5
Answer: x=13
Step-by-step explanation: Hope this help :D
Answer:
One Solution
__________
x = 13
__________
Explanation:
| x – 13 | – 5 = -5
[Add 5 to both sides to isolate | x – 13 | and cancel out –5]
| x – 13 | – 5 + 5 = -5 + 5
[Reduce]
| x – 13 | = 0
[An absolute value can include both a positive and negative value so |x| = n → x = ±n ]
x – 13 = ± 0
[Add 13 to both sides to get the value of x]
x – 13 + 13 = 13 ± 0
x = 13 ± 0
[Adding or subtracting zero will leave you with the same number]
x = 13

The half-life of Palladium-100 is 4 days. After 12 days a sample of Palladium-100 has been reduced to a mass of 7 mg.
Answer:
I think this is correct but im not sure..
Step-by-step explanation:
12 days is 3 half-lives ... so, 1/8 initial ... (1/2)^3 = 1/8
... initial is 8 mg
4 weeks is 7 half-lives ... 8 mg * (1/2)^7 = ?
Answer:
56 mgStep-by-step explanation:
Let the initial mass of sample is x mgWe have the following equation:
x* [tex](\frac{1}{2}) ^{12/4}[/tex]= 7x*[tex](\frac{1}{2}) ^{3}[/tex] = 7x*[tex](\frac{1}{8} )[/tex] = 7x = 7*8x = 56 mgPianni Beverages produce two ready-mixed cocktail drinks; the Zombie and the Skyjack.
