Selena earned $4,283.30 last month. She used of her earnings to pay her bills. With the remaining money, she
bought two shirts for $19.99 each and a pair of sunglasses for $12.99. How much money does Selena have left from last
month's earnings?
Answer:
$4,256.31
Step-by-step explanation:
4,283.30 - 2(19.99) + 12.99 = x
Initial value (last month's earnings) - the two shirts, which were both 19.99 and the pair of sunglasses, which were 12.99.
4256.31 = x

Suppose there is an excess demand for cell phones. In a market without price controls market pressures will cause the price of cell phones to ____ until it reaches the equilibrium price
Answer:
Step-by-step explanation:
rise/increase/grow
Answer:
Step-by-step explanation:
The key word is increase.
People who don't have a cell phone will bid the price up until some of the people wanting a cell drop out of the bidding. Then only those willing to pay a higher price will be left to buy the cell at a much higher price than was initially thought to be the right price.
Phew. Try reading that sentence a couple of times. It's right, but there should be an easier way to say it.
500 is what percent of 125?
Answer:
400
Step-by-step explanation:
Solution for 500 is what percent of 125:
500:125*100 =
(500*100):125 =
50000:125 = 400
Now we have: 500 is what percent of 125 = 400
Question: 500 is what percent of 125?
Percentage solution with steps:
Step 1: We make the assumption that 125 is 100% since it is our output value.
Step 2: We next represent the value we seek with [tex]x%[/tex].
Step 3: From step 1, it follows that $100%=125$.
Step 4: In the same vein, $x%=500$.
Step 5: This gives us a pair of simple equations:
100%=125(1)
x%=500(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left-hand side) of both equations have the same unit (%); we have
[tex]\frac{100\%}{x\%}=\frac{125}{500}[/tex]
Step 7: Taking the inverse (or reciprocal) of both sides yields
[tex]\frac{x\%}{100\%}=\frac{500}{125}[/tex]
[tex]\Rightarrow x=400\%[/tex]
Therefore, 500 is 400% of 125
Hope this answer helps and answers your question! Have a great day/night!
What is the present value of an investment that will be worth $6000 at the end of five years? Assume an APR of 6% compounded monthly. (Round your answers to the nearest cent.)
Answer:
4448.23
Step-by-step explanation:
[tex]AV=PV(1+\frac{i}{n})^{nt}\\\\6000=PV(1+\frac{.06}{12})^{5*12}\\\\6000=PV*1.3488\\\\PV= 4448.23[/tex]
The present value of an investment that will be worth $6000 at the end of five years is, $4448.23
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Annual value = $6,000
Time = 5 years
Rate = 6%
Hence, We get;
A = P (1 + r/n)ⁿˣ
Substitute all the values, we get;
⇒ 6000 = P (1 + 0.6/12)⁶⁰
⇒ 6000 = P × 1.3488
⇒ P = $4448.23
Thus, The present value of an investment that will be worth $6000 at the end of five years is, $4448.23

2(2x+2) ????????????????????????
Answer:
4x+4
Step-by-step explanation:
2(2x+2)
Distribute the first 2 to each term inside the parentheses
2 * 2x + 2 *2
4x+4
Answer:4x+4
Step-by-step explanation:
Multiply the numbers in the parentheses by 2
2 times 2x=2x+2x=4x
2 times 2=4
So....4x+4 is the answer

Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with μ=101 and σ=24. (a) what proportion of children aged 13 to 15 years old have scores on this test above 83 ? (note: please enter your answer in decimal form. for example, 45.23% should be entered as 0.4523.)
Answer:
a) 0.7734
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 101, \sigma = 24[/tex]
(a) what proportion of children aged 13 to 15 years old have scores on this test above 83 ?
This is 1 subtracted by the pvalue of Z when X = 83. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{83 - 101}{24}[/tex]
[tex]Z = -0.75[/tex]
[tex]Z = -0.75[/tex] has a pvalue of 0.2266
1 - 0.2266 = 0.7734
The answer is 0.7734

An account earns annual simple interest. Find the balance of the account.
$5,000 at 6% for 9 months.
Answer:
$7700
Step-by-step explanation:
As the account earns 6% interest, if we find 6% of $5000 we get $300, the interest is simple and given every month, meaning you get $2700 in interest as $300 x 9 months = $2700
$5000 initial + $2700 interest = $7700
EDIT:
It could be that the interest is 6% yearly, which means that yearly you get 6% interest, and the answer is $5225.
6% interest is $300 per year
$300÷12= $25 per month
$25 x 9 months = $225
$5000 initial plus $225 interest = $5225 total
Micah jogged 8/10 of a mile. Sarah jogged 3 times this distance. How far did Sarah jog? Explain
Answer:
2.4 miles or 12/5 miles
Step-by-step explanation:
well if we take the amount Micah jogged (8/10 miles) and we multiply that by 3 in order to get Sarah's distance
it leaves us with
24/10 and that simplified will be
12/5 miles
in decimals that would be
2.4 miles

A football player completes a pass 67.9% of the time.Find the probability that the first pass he completes is the second pass.
Answer:
0.2587 = 25.87% probability that the first pass he completes is the second pass.
Step-by-step explanation:
Probability that the first pass he completes is the second pass.
Misses the first, with a 100 - 67.9 = 38.1% = 0.381 probability.
Completes the second, with 0.679 probability. So
0.381*0.679 = 0.2587
0.2587 = 25.87% probability that the first pass he completes is the second pass.
