Kevin drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 9 hoursWhen Kevin drove home, there was no traffic and the trip only took 4 hours. his average rate was 40 per hour faster on the trip home, how far away does Kevin live from the mountains? Do not do any rounding
Answer:
288 miles
Step-by-step explanation:
Kevin's trip took 9 hours one way, and 4 hours the other way, driving 40 mph faster. You want to know the one-way length of Kevin's trip to the mountains.
SetupThe relation between time, speed, and distance is ...
speed = distance/time
Using d to represent the one-way distance Kevin drove, we can relate his speeds with ...
d/4 = 40 +d/9 . . . . . . speed coming home was 40 mph more than going
SolutionMultiplying by 36 to clear fractions, we have ...
9d = 1440 +4d
5d = 1440 . . . . . . . subtract 4d
d = 288 . . . . . . . divide by 5
Kevin lived 288 miles from the mountains.

Answer:
83° 59'
Step-by-step explanation:
The numbers given refer to degrees and minutes for two angles
We read them as follows
62° 18' ==> 62 degrees and 18 minutes
21° 14' ==> 21 degrees and 41 minutes
60 minutes make up 1 degree
We simply add the individual components together. If the number of minutes is 60 or greater then we have to convert those minutes to degree and minutes and add to the total degrees
In this case it is a simple addition since 18' + 41' = 59' and is less than 60
So 62° 18' + 21° 14'
==> Add the degrees separately ==> 62 + 21 = 83°
==> Add the minutes separately ==> 18' + 41' = 59'
Put the two components together to get
83° 59'

A sale at a store is 15%. If the sale price after
the discount is $35.70. What was the original
price of the sweatshirt (S)?
Answer:
$42.00
Step-by-step explanation:
Let x = the original cost of the sweatshirt
x - .15x = 35.70 We don't know the original cost so we will call it x. I know that we are taking 15 off of this number to get the sale's price. 15% means per 100, so as a fraction this would be 15/100. To make this a decimal, I would divide 15 by 100 to get .15
x - .15x = 35.70 Combine the like terms
.85x = 35.70 This is say that 85% if the original price is the sale price of 35.70
Divide both sides of the equation by .85 and we get x = 42.00
Check:
42 - .15(42) = 35.70
42 - 6.30 = 35.70

On September 22, 2021, the market value of the investments contained in the Martindale Balanced Fund, a mutual fund, was $39,400,000, Liabilities for the
fund were $3,940,000.
If the fund had 1,380,000 shares outstanding, calculate the net asset value per share. Round your answer to the nearest cent.
Answer:
$25.70 (nearest cent)
Step-by-step explanation:
Given:
Market value = $39,400,000Liabilities = $3,940,000Outstanding shares = 1,380,000[tex]\begin{aligned} \textsf{Net Asset Value}_{\textsf{(Per Share)}} & =\dfrac{\textsf{Fund Assets}-\textsf{Fund Liabilities}}{\textsf{Total number of Outstanding Shares}}\\\\\implies \textsf{Net Asset Value}_{\textsf{(Per Share)}} & = \dfrac{\$39,400,000-\$3,940,000}{\$1,380,000}\\\\& = \dfrac{\$35,460,000}{\$1,380,000}\\\\& = \$25.69565217...\\\\\end{aligned}[/tex]
Therefore, the Net Asset Value (NAV) per share is $25.70 (nearest cent).
The given information is,
→ x = $39,400,000
→ y = $3,940,000
→ z = 1,380,000
Formula we use is,
→ (x - y)/z
Now the net asset value per share is,
→ (x - y)/z
→ (39400000 - 3940000)/1380000
→ 35460000/1380000
→ 25.6956521739
→ ≈ $25.70
Hence, the net asset value is $25.70.
Scott rented a truck for one day. There was a base fee of $18.99, and there was an additional charge of 92 cents for each mile driven. Scott had to pay $150.55 when he returned the truck. For how many miles did he drive the truck?
I need to find how many miles
Answer:
143 miles
Step-by-step explanation:
Let x = number of miles
Let y = total cost
150.55 = .92x + 18.99 Multiply all the way through by 100 to clear the decimal
15055 = 92x + 1899 Subtract 1899 from both sides
13156 = 92x Divide both sides by 92
143 = x
The table below models a particular physical situation.
x −9 −3 4 10
y 9 1 −7 10
Find the piecewise linear equation that models the data above. Round to three decimal places if needed.
y={
___ x + ___. −9 ≤ x ≤ −3
___ x + ___. −3 < x ≤ 4
___ x + ___. 4 < x ≤ 10
The piecewise linear function that models the situation is given as follows:
y = -4/3x + b, −9 ≤ x ≤ −3,y = -8/7x - 17/7, −3 < x ≤ 4,y = 17/6x - 110/6, 4 < x ≤ 10.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.A piecewise function is a function that has different definitions based on the input.
For x between -9 and -3, the function decreases by 8 when x increases by 6, hence the slope is given by:
m = -8/6 = -4/3, hence:
y = -4/3x + b.
When x = -9, y = 9, hence we use it to find b as follows:
9 = -4/3(-9) + b
9 = 12 + b
b = -3.
Thus the first definition is:
y = -4/3x + b, −9 ≤ x ≤ −3
For x between -3 and 4, the function decreases by 8 when x increases by 7, hence the slope is given by:
m = -8/7
y = -8/7x + b.
When x = -3, y = 1, hence we use it to find b as follows:
1 = -8/7(-3) + b
1 = 24/7 + b
b = -17/7
Thus the second definition is:
y = -8/7x - 17/7, −3 < x ≤ 4.
For x between 4 and 10, the function increases by 17 when x increases by 6, hence the slope is given by:
m = 17/6
y = 17/6x + b.
When x = 10, y = 10, hence we use it to find b as follows:
10 = 17/6(10) + b
b = 10 - 170/6
b = -110/6
Thus the third definition is:
y = 17/6x - 110/6, 4 < x ≤ 10

500 values are normally distributed with a mean of 125 and a standard deviation of 10 which percent of the values lies between 115-125
The percent that the value is between 115 - 125 is 34.13%.
What is defined as the standard normal distribution?A standard normal distribution is a symmetric probability distribution with equal mean, mean, and mode values. The value of the probability of a standard normal distribution is achieved from a statistical table or computer software.For the given question;
The total number of the sample is 500.
The mean of the sample is; μ = 125.
The standard distribution is; σ = 10.
The percentage of the values must lie between 115-125.
Thus,
P(115 < X < 125) = P[(115 - 125)/10 < (x - μ)/ σ < (125 - 125)/10]
= P[-1 < Z < +0]
Z for +0 = 0.50000 and z for -1 = 0.15866 obtained from Z-score table.
P(115 < X < 125) = [0.50000 - 0.15866]
P(115 < X < 125) = 0.34134
P(115 < X < 125) = 34.13%
Therefore, the probability for percent of the values lies between 115-125 is 34.13%.

A line passes through point 6, 1 and has a slope of 43. Write an equation in =+AxByC form for this line. Use integers for A, B, and C.
Answer:
4x-3y=21.
Step-by-step explanation:
1) the common view of slope-interception form is y=slope*x+interception;
2) if according to the condition the slope=4/3, then the required equation is
[tex]y=\frac{4}{3}x +interception;[/tex]
3) in order to calculate the interception it is enough to substitute the given coordinates into this equation:
[tex]1=6*\frac{4}{3} +interception; \ = > \ interception=-7;[/tex]
4) the slope interception form of the required equation is:
[tex]y=\frac{4}{3}x-7;[/tex]
5) if to re-write the equation in slope-interception form into the required, then (A=4; B=-3; C=21):

If f(n) = 2n^2 + 2n and g(n) = n + 1, what is (f ÷ g)(n) when n = -2?
Answer:
The answer is -4.
Step-by-step explanation:
Since its f/g, we know that f(n)= 2n^2+2n and g(n)=n+1.
N= -2. You will plug in all the values of n = - 2.
So...
2n^1+2n/n+1
2(-2)^2+2(-2)/-2-1 which will give you -4.
You are about to list your house as For Sale By Owner. Suppose you need to allow
for a 3% commission for the buyer's realtor, and you need to receive a minimum of
$92,500 on the sale. What is the minimum price you can list the house at to
accommodate both of these requirements? Round to the nearest hundred dollars.
$89,725
$95,275
$95,400
$95,000
Answer:
(c) $95,400
Step-by-step explanation:
You want the listing price of your house such that you can clear $92,500 after paying a 3% commission to the buyer's realtor.
SetupThe buyer's agent will receive 3% of the sale price (P), so you receive that amount less. You want your share to be $92,500.
(1 -3%)P = 92,500
SolutionDividing by the coefficient of P, we get ...
P = 92,500/0.97 ≈ 95,361
We are asked to round this value to the nearest $100. That makes the listing price ...
$95,400 . . . . listing price
__
Additional comment
You can estimate the listing price by adding 3% of 92500 to that value, and you can estimate the added amount as 3%×90,000 = 2700. That is, you know the listing price needs to be slightly higher than ...
92500 +2700 = 95,200
Only one of the answer choices is above that value and rounded to the nearest $100. (You can eliminate the first two choices, because they are not properly rounded.)

The equation after completing the square is (z + 4)² = 80
The solutions to the given equation in the simplest radical form are z = -4 + 4√5 and z = -4 - 4√5
Completing the squareFrom the question, we are to solve the given quadratic equation by completing the square
The given equation is
z² +8z - 44 =20
First, add 44 to both sides of the equation
z² +8z - 44 + 44 = 20 + 44
z² +8z = 64
Now, divide the coefficient of z by 2, square the value and add to both sides
The coefficient of z is 8
Dividing
8/2 = 4
Squaring
4²
Now, add this to both sides
That is,
z² +8z +4² = 64 + 4²
(z + 4)² = 64 + 16
(z + 4)² = 80
The equation after completing the square is
(z + 4)² = 80
Continuation
(z + 4)² = 80
Take the square root of both sides
√(z + 4)² = ±√80
z + 4 = ±√80
z = -4 ± √80
z = -4 ± 4√5
z = -4 + 4√5 and z = -4 - 4√5
Hence,
The equation after completing the square is (z + 4)² = 80

Since this is a probability question, you have to add the marbles together and divide by the probability that it's asking for. So...
# of R marbles = 3
# of G marbles = 5
# of B marbles = 2
# of W marbles = 1.
So add it together and you will get 11.
Now, divide the number of marbles/total number of R marbles.
3/11
