Jessica buys a coat online for $70. If shipping and handling are an additional 20% of the price, how much shipping and handling will Jessica pay?
Answer:
$14 in shipping and handling
Step-by-step explanation:
20 percent as a decimal is .2, so multiply 70 by .2 to determine what twenty percent of 70 is. You should get 14, which is how much shipping and handling she will pay.

What single percentage change is equivalent to a 9% increase followed by a 17% increase?
Answer:
27.53%
Step-by-step explanation:
Initial number = 100
9% increase
100*1.09= 109
17% increase
109*1.17= 127.53
The difference with the initial number is:
127.53 - 100 = 27.53
27.53/100*100% = 27.53%
This is the single percentage change

Find all real solutions Tan pi/3 x-3=0
Step-by-step explanation:
If the question is like this,
[tex] \tan( \frac{\pi}{3}x - 3 ) = 0[/tex]
We take the arc tan of both sides.
[tex] \tan( - 1) ( \tan( \frac{\pi}{3}x - 3 ) = \tan {}^{ - 1} ( {}^{ }0 ) [/tex]
[tex] \frac{\pi}{3} x - 3 = 0[/tex]
[tex] \frac{\pi}{3} x = 3[/tex]
[tex] = \frac{9}{\pi} [/tex]
Since the period of a tan function, is pi, we divide pi by pi/3 since pi/3is the coeffeicent of the x variable
[tex] \frac{\pi}{ \frac{\pi}{3} } = 3[/tex]
So the answer is
[tex] \frac{9}{\pi} + 3n[/tex]
If this the question,
[tex] \tan( \frac{\pi}{3} x) = 3[/tex]
[tex] \frac{\pi}{3} x = 1.249[/tex]
[tex]x = \frac{3.747}{\pi} [/tex]
The period is once again 3 so we have
[tex] \frac{3.747}{\pi} + 3n[/tex]
where n is a interger.
How many solutions does the system of equations below have?
y = 3x + 4
y+ 6 = 3x
O A. Exactly 1 solution
O B. More than 1 solution
O C. At least 1 solution
O D. No solution
Answer:
No solution
Step-by-step explanation:
Let's solve your system by substitution.
y=3x+4;y+6=3x
Step: Solvey=3x+4for y:
y=3x+4
Step: Substitute3x+4foryiny+6=3x:
y+6=3x
3x+4+6=3x
3x+10=3x(Simplify both sides of the equation)
3x+10+−3x=3x+−3x(Add -3x to both sides)
10=0
10+−10=0+−10(Add -10 to both sides)
0=−10

let f(x) = -2x -7 and g(x) = -4x+3. Find (f.g) (-5)
Answer:
-53
Step-by-step explanation:
I assume your question is asking for x = -5 when (f.g).
Simply plug in the equation g(x) into the variable x of the f(x) function.
[tex](fog) = -2(-4x+3)-7[/tex]
Plug in x = -5 and the answer will be -53.
Write these values in order, starting with the smallest.
0.15
1/10
12%
1/20
Rewrite them all as a decimal to compare them:
0.15
1/10 = 0.10
12% = 0.12
1/20 = 0.20
Now write them in order : 1/10, 12%, 0.15, 1/20
Suppose the distributor charges the artist a $50.00 cost for distribution, and the streaming services pay $ 5.00 per unit. (Note: One unit = one thousand streams) Model the profit for the total number of streams by answering the questions below:
1. Use the cost for distribution to build the y-intercept. What is the y-intercept?
Hint: the y-intercept is a point on the y axis, so the answer should be an ordered pair
(x,y). Keep in mind that money is being spent, and therefore must be deducted from the profit. If the y-intercept is incorrect, all related numbers will be incorrect.)
2. Use the payment per unit to build the slope. What is the slope?
Equation in slope intercept form
y=mx+by=5x+50Slope:-m=5
Y intercept=b=50
The y-intercept of the function is (0, 50) and the slope of the function is 5
How to calculate the slope and y-intercept of a function?Slope is defined as the rate of change of function. Given the following parameters
Fixed price = $50
If the streaming services pay $ 5.00 per unit, then the rate of change is $5
The required profit for the total number of streams is given as:
P(x) = 50 + 5x
1) The y-intercept is the point where the value of x is zero
P(x) = 50 + 5x
P(0) = 50 + 5(0)
P(0) = 50
Hence the y-intercept of the function is (0, 50)
For the slope
mx = 5x
m = 5
Hence the slope of the function is 5

In Mr. Kagame's Algebra 1 class, 7 students took the Unit 7 test. The class average was 78% (rounded). Six students' scores are known:HELPPP
The score of the seventh student will be given by:
[tex]x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]
What is the score of the last student?
So you know the scores of 6 of the students, let's define these as:
a₁, a₂, a₃, a₄, a₅, a₆.
And let's define x as the score of the 7th student.
We know that the average of the scores is 78% (rounded).
Then we can estimate the value of x using the average equation:
[tex]\frac{a_1 + a_2 + a_3 + a_4 + a_5 + a_6 + x}{7} = 78[/tex]
Now you can solve that for x, to get:
[tex]x = 78*7 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6\\\\x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]
That is the equation to get the score of the seventh student as a function of the six known scores.

4b) Find the area of the following shapes.
Answer:
180
Step-by-step explanation:
To find the area of the rectangle, multiply 15 by 9
15 x 9 = 135
To find the area of the triangle, multiply 15 by 6, then divide by 2
15 x 6 = 90
90/2 = 45
Now add these two numbers to get the total area.
135 + 45 = 180

if RST is an equilateral triangle, find x and the measure of each side.
S 12x - 22 R 10x - 6 T 7x + 18
O X=8
O X=6
O X=4
O X=2
Answer:
x = 8
Step-by-step explanation:
In equilateral, the length of the sides are equal.
12x - 22 = 10x - 6
Add 22 to both the sides
12x = 10x - 6 + 22
12x = 10x + 16
Subtract '10x' from both sides,
12x -10x = 16
2x = 16
Divide both sides by 2
x = 16/2
x = 8
