A local screen-printing company sells T-shirts at various prices, in dollars, depending upon how many T-shirts are bought at the time. The piecewise function below represents their pricing structure, where n is the number of T-shirts purchased. The school volleyball team purchased 20 shirts.
How much did the volleyball team spend on shirts?
$480
$180
$220
$260
Answer:
i think it’s 260 too^^
Step-by-step explanation:
The total Amount Spent by the volleyball team spend on shirts from the given piecewise function is; $260
How to work with Piecewise Function?
From the given piecewise function, we see that;
y = {13n, 0 < n ≤ 20
y = {11n, 20 < n ≤ 50
y = {9n, n > 50
We are told that the volleyball team purchased 20 shirts.
From the first piecewise function, we can deduce that;
Amount Spent = 13n = 13 * 20
Amount Spent = $260

Solve the inequality 7y-35<2(x-5)
Answer:
x < 5
Explanation:
7*x-35-(2*(x-5))<0
(7x - 35) - 2 • (x - 5) < 0
Pull out like factors :
5x - 25 = 5 • (x - 5)
5 • (x - 5) < 0
Divide both sides by 5
Add 5 to both sides
x < 5

he slope of the line that contains the points (1, -1) and (2, 3) is 4. What is the y-intercept? A. 5 B. 4 C. -4 D. -5
Answer:
D
Step-by-step explanation:
Equation of a line given by the two-point form is:
(y-y1)/(x-x1) = (y1-y2)/(x1-x2)
(y-(-1))/(x-1) = (-1-3) / (1-2)
(y+1)/(x-1) = -4 / -1
y+1 = 4(x-1)
y = 4x-4-1
y = 4x - 5
y-intercept at x=0 is -5
Answer is D.
Solution:
We know that:
Given points: (1, -1) and (2, 3)Slope = 4Picking any point:
=> (1, -1)Using point slope form:
y - y₁ = m(x - x₁)y - (-1) = 4(x - 1)y + 1 = 4x - 4y = 4x - 4 - 1y = 4x - 5Comparing the equation with the formula:
y = (m)x + (b) and y = (4)x + (-5)⇒ m = slope = 4
⇒ b = y-intercept = -5

Cate randomly samples the out-of-state tuition and fees for 25 public universities and found a mean of $20,340 with a standard deviation of $2,494. Using the alternative hypothesis that µ < $21,706, Cate found a z test statistic of -2.74. Given the data provided, what is the p-value of the z-test statistic?
Answer:
0.003
Step-by-step explanation:
Recall for a p-value, it must be a value that is as extreme and more extreme than the test statistics. If we go to the chart for the z-score and go to the row of -2.7 and to the column 0.04, we can see the value is 0.0031 or 0.003. Since the test is a one-tailed test (note that is less than, "<"), this is the p-value.

Blank - 3/10 = 1/5 What is the blank number
Answer:
1/2
Step-by-step explanation:
Let's consider the number we want is x
x-3/10=1/5
On both sides of the equation, if we substract (or add) a certain number, say 3/10, the equality relation still exists.
That is x-3/10+3/10=1/5+3/10
Then x=1/5+3/10
You see 1/5+3/10=2/10+3/10=1/2
So x=1/2

A TV can be purchased from the manufacturer for $250. An online retailer has a markup of 30%, and a superstore has a standard markup of 40%.
(a) What is the price of the TV when purchased online?
(b) What is the price of the TV when purchased at the superstore?
(c) Which has the better deal – the online retailer or the superstore?
Answer:
(a) 325
(b) 350
(c) The online retailer has a better deal.
Step-by-step explanation:
250 * 130% = 325
25- * 140% = 350
325 is less than 350, so its the better deal.

Help Me On This Plss!!
Step-by-step explanation:
Hello, first you have to substitute x=-3 in 12-3x which is 12-3(-3)= 12+9=21. So number 1 is 21. You continue like that till you finish.
2. You substitute x=-3 in y=x^2 +3x - 2. So that would be y= - 3^2+3(-3)-2. Which is 9+(-9)-2 which will be 9-9-2=-2. So the first blank space for number 2 is - 2.

Answer:
h = 1053 ft (to the nearest foot)
Step-by-step explanation:
The sum of the interior angles of a triangle is 180°
Therefore, the angle at the bottom vertex of the triangle is:
180 - 69.2 - 65.5 = 45.3°
Sine rule:
[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
where A, B and C are the angles in a triangle, and a, b and c are the sides opposite those angles (e.g. side a is opposite angle A).
Now we can use the sine rule to calculate the length of the diagonal sides of the triangle.
Let a = the length of the right diagonal (the side with unknown length adjacent to angle 65.5°)
[tex]\dfrac{a}{\sin(69.2)}=\dfrac{880}{\sin(45.3)}[/tex]
[tex]\implies a=1157.353973...[/tex]
Now we can use the sine trig ratio to determine h:
[tex]\sin(65.5)=\dfrac{h}{1157.353973...}[/tex]
[tex]\implies h=1053.147292...[/tex]
Therefore, h = 1053 ft (to the nearest foot)
Answer:
1053 feet
Step-by-step explanation:
We choose to solve this problem using the tangent relation. It relates an acute angle to the adjacent and opposite legs of a right triangle.
Tan = Opposite/Adjacent
Opposite = Adjacent × Tan
__
For this to be useful here, we need to know the angles at the bottom of the figure. The left-side angle is 90° -69.2° = 20.8°. The right-side angle is 90°-65.5° = 24.5°. The tangent relation tells us ...
bridge left side + bridge right side = 880 ft
h×tan(20.8°) +h×tan(24.5°) = 880 ft
h = (880 ft)/(tan(20.8°) +tan(24.5°)) = (880 ft)/(0.37986 +0.45573)
h ≈ 1053.147 ft
The bridge is about 1053 feet high.
A local card store marks up the price of all the items they sell by 15%. If the store buys photo albums for $7.00 each, at what price will they sell them?
Answer:
$8.05
Step-by-step explanation:
This answer is found by making an equation that represents this word problem which uses the formula %(decimal form)(original price).
Using this formula, the equation representing this word problem is 0.15(7).
When evaluated, gives us $1.05 (the mark up).
Then, this must be added to the original price using the formula (original price+mark up);
1.05+7.00
Answer= $8.05
