Marcus is buying a pair of running shoes that are discounted 20% from the original price
of $100. The store is also having a holiday sale, so they will take an additional 20% off the
sale price. How much will Marcus pay for his shoes?
Answer: $64
Step-by-step explanation:
20% of 100 is 20 so 100-20=80. Also 20% of 80 is 16. So 80-16=64. So that’s the answer.

[tex]\frac{x}{5}[/tex] + 7 = -3
Answer:
[tex]\huge{\fbox{\sf{ x = -50}}}[/tex]
Step-by-step explanation:
[tex]\frac{x}{5} + 7 = -3[/tex]
Take the L.C.M of 5 and 1 ( i.e 5 )
⇒[tex]\frac{x+7 * 5}{5} = -3[/tex]
⇒[tex]\frac{x+35}{5} = -3[/tex]
Do cross multiplication
⇒[tex]x + 35 = -3 * 5[/tex]
⇒[tex]x + 35 = -15[/tex]
Move 35 to right hand side and change its sign
⇒[tex]x = -15 - 35[/tex]
Remember : The negative integers are always added but posses the negative ( - ) sign.
⇒[tex]x = -50[/tex]
The value of x is [tex]\boxed{\sf{ -50}}[/tex]

Here's a linear equation in variable x and we have to compute the value of x for the above equation.
Given equation:
[tex] \large{ \rm{ \dfrac{x}{5} + 7 = - 3}}[/tex]So, Let's start solving the above equation:
Move 7 to the Right hand side,
Remember: Inverse of addition is subtraction
[tex] \sf{ \dfrac{x}{5} = - 3 - 7}[/tex]
[tex] \sf{ \dfrac{x}{5} = - 10}[/tex]
Now multiplying 5 in other side because again the inverse of division is multiplication,
[tex] \sf{ x = - 10 \times 5}[/tex]
[tex] \sf{x = \boxed{ \red{ - 50}}}[/tex]
And the required value for x is -50. So, we are done....

What is the effective annual rate for an APR of 10.60 percent compounded quarterly?
Answer:
The effective annual rate is 11.03%
Step-by-step explanation:
The effective interest rate is calculated through the formula:
[tex]r = (1 + i/n)^n - 1[/tex]
In this formula, r represents the effective interest rate, i represents the stated interest rate or APR, and n represents the number of compounding periods per year.
For a quarterly compounded interest, n=4. The APR i=10.60%=0.106
Given an APR r, the effective annual rate for a quarterly compound is:
[tex]r = (1 + 0.106/4)^4 - 1=1.0265^4-1[/tex]
[tex]r=1.11029-1=0.1103[/tex]
The effective annual rate is 11.03%

During the first half of a football game, a running back ran for 9 total yards. In the second half, he ran for a loss of 12 yards. What was the running back's total yardage?
Answer:
21
Step-by-step explanation:
The running back's total yardage is 21 yards
From the question we are given the following parameters
Distance travelled in the first half of the game is 9 yards
Distance travelled in the second half of the game is 12 years
In order to determine the running back's total yardage, we will take the sum of the distance travelled as shown
Total distance travelled = 9 yards + 12 yards
Total distance travelled = 21 yards
Hence the running back's total yardage is 21 yards

Consider the population of the city of Beaumont. Over the course of a year, 800 people move into town. Of those that moved in, 180 have dark hair, 260 have red hair, and the remaining 360 are blonde. During this year a total of 1070 people move out, 470 with dark hair, 270 redheads, and 330 blondes. There are 223 newborns, 47 with dark hair, 90 with red hair, and 86 blondes. Finally, there are 168 deaths, 31 with dark hair, 66 with red hair, and 71 with blond hair. (Assume no one goes bald or changes their hair color.) What is the accumulation of red-haired people in Beaumont, for this year
Answer:
There were 14 red-haired people accumulated in Beaumont, for this year.
Step-by-step explanation:
The number of people who moved into town is = 800Number of dark haired people = 180
Number of red haired people = 260
Number of blonde haired people = 360
The number of people who moved out of town is = 1070Number of dark haired people = 470
Number of red haired people = 270
Number of blonde haired people = 330
The number of newborns in town is = 800Number of dark haired = 47
Number of red haired = 90
Number of blonde haired = 86
The number of deaths in town is = 168Number of dark haired people = 31
Number of red haired people = 66
Number of blonde haired people = 71
Compute the accumulation of red-haired people in Beaumont, for this year as follows:
Red hair = #Moved in - #Moved out + #Newborn - #Deaths
= 260 - 270 + 90 - 66
= 14
Thus, there were 14 red-haired people accumulated in Beaumont, for this year.
What is the rate if change for y = x - 4
Answer:
The rate of change is 1
Step-by-step explanation:
This is because the slope is x, and -4 is just the y-intercept, which has nothing to do with the slope. Because the slope is x, that means that it is positive 1.
Answer:
Rate of Change = 1
Step-by-step explanation:
Rate of Change = Slope = m
y = mx + b
y = (1)x -4
m = 1

Company A sells hats for $11 per hat plus a fixed $7 shipping and handling fee. Company B sells hats for $8 per hat plus
a fixed $16 shipping and handling fee. The marketing director of company A wants to set up a system of equations to find
the number of hats for which the total cost of an order for the two companies is the same. He uses the variables x and y.
He lets y represent the total cost of an order. What will x represent?
O x = total cost of an order
O x = shipping costs for company B
O x = shipping costs for company A
O x= number of hats
Answer:
Its D
Step-by-step explanation:
x represents the number of hats.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given, Company A sells hats for $11 per hat plus a fixed $7 shipping and handling fee. Company B sells hats for $8 per hat plus a fixed $16 shipping and handling fee.
Let x be the number of hats and y be the total cost for x hats
For Company A:
per hat charges = 11
charge for x hats = 11 * x
Since, shipping charges = 7
Thus,
Total cost for x hats, y = 11x + 7
For Company B:
per hat charges = 8
charge for x hats = 8 * x
Since shipping charges = 16
Thus,
Total cost for x hats, y = 8x + 16
If the Cost is the same,
11x + 7 = 8x + 16
3x = 9
x = 3
therefore, If we order 3 hats then the cost from both companies will be the same. and x represents the number of hats.

How do I work this problem -16f+13=2f-11
Answer:
f = 4/3
Step-by-step explanation:
-16f + 13 = 2f - 11
24 = 18f
Divide
24/18 = f
4/3 = f
[tex] - 16f + 13 = 2f - 11[/tex]
Subtract sides -13
[tex] - 16f + 13 - 13 = 2f - 11 - 13 \\ [/tex]
[tex] - 16f = 2f - 24[/tex]
Subtract sides -2f
[tex] - 16f - 2f = 2f - 2f - 24[/tex]
[tex] - 18f = - 24[/tex]
Negatives simplifies
[tex]18f = 24[/tex]
Divided sides by 18
[tex] \frac{18}{18}f = \frac{24}{18} \\ [/tex]
[tex]f = \frac{4}{3} \\ [/tex]

For what values of the variable does each of the following expressions make sense? We call the set of this values the domain of the expression. \sqrt{4-6a}
Given:
The expression is [tex]\sqrt{4-6a}[/tex].
To find:
The domain of the expression.
Solution:
We have,
[tex]\sqrt{4-6a}[/tex]
We know that, the square root is defined for only non-negative values. So,
[tex]4-6a\geq 0[/tex]
[tex]4\geq 6a[/tex]
Divide both sides by 6.
[tex]\dfrac{4}{6}\geq a[/tex]
[tex]\dfrac{2}{3}\geq a[/tex]
Thus, the value of variable less than [tex]\dfrac{2}{3}[/tex] make any sense.
Therefore, the domain of the given expression is [tex](-\infty,\dfrac{2}{3}][/tex].
The domain of a function is the set of input values the function can take
The domain of the expression is: [tex]\mathbf{(-\infty, \frac 23]}[/tex]
The expression is given as:
[tex]\mathbf{\sqrt{4 - 6a}}[/tex]
Set the radicand to 0
[tex]\mathbf{4 - 6a = 0}[/tex]
Add 6a to both sides
[tex]\mathbf{6a = 4}[/tex]
Divide both sides by 6
[tex]\mathbf{a = \frac 23}[/tex]
This means that, the value of a must not be greater than 2/3.
Hence, the domain of the expression is: [tex]\mathbf{(-\infty, \frac 23]}[/tex]
