Answer: 360
Step-by-step explanation:
Since we are informed from the question that Alicia surveyed 50 students in the cafeteria from the population of 300 students, it simply means that she surveyed 50/300 = 1/6 of the students.
Since Thea surveyed the first 60 students who arrived at school one morning, the number of T-Shirts taht they should order will be:
= 1/6 × x = 60
x = 60 × 6.
x = 360
They should order 360 t-shirts for the students.
Answer: Look at the explanation. Note that this is from the book.
Step-by-step explanation:
Alicia: 30/50 = x/30
x=180
They should order about 180 T-shirts.
Thea: 51/60 = x/300
x = 255
They should order about 255.
Note that we got the 300 from what the question said of the population being 300 students.
Hope this helps you!

p-5 = 19
answer step by step & explain
Answer:
Step-by-step explanation:
Very simple.
p - 5 = 19
So to take out the -5 on that side, you must also do the same thing to the other side. So adding 5 in one side of the equal sign would mean you have to do the same thing on the other side of the equal sign.
SO:
p-5 +5 = 19+5
p = 24
Please find the area of the trapezoids.
By the way, the answer is NOT 10.5.
Answer:
42 square units
Step-by-step explanation:
Hello There!
The area of a trapezoid can be found using this formula
[tex]a = \frac{a + b}{2} h[/tex]
where a and b are bases and h is height
if you look at the graph we can see that the lines are counting by 2 units
knowing this we want to find the dimensions
the shown trapezoid has the following dimensions
a =2*2 or 4
b=5*2 or 10
h=3*2 or 6
having found this information we then plug it into the formula
[tex]a = \frac{4+ 10}{2} 6 \\ 4 + 10 = 14 \\ \frac{14}{2} = 7 \\ 7 \times 6 = 42[/tex]
so we can conclude that the area of the trapezoid is 42 square units
Surface Area
6. Answer the question above (use 3.14 for pi):
Preface: We know that the radius of the cylinder is 2 inches and the height is 7 inches. Using the surface area formula (for a cylindrical figure), which has been provided below, we can, through calculations, figure out that the surface area of the cylinder is...
Formula: A = 2π × r × h + 2πr2= 2πr (h + r)
Variables: The "A" is the answer; "R" represents the radius and the "H" is the variable for the height of the cylinder. For the purpose of this question, we'll substitute 3.14 for pi (π).
Surface Area ≈ 113.1, or if you want the exact solution: 113.09734.
help me pls asap its to hard my brains about to explode
Answer:
1. c = 5.75b + 25
2. y = -1/3 + 5
3. y = -1/2 + 5
4. y = I can't tell what the numbers are from the photo, but (B) will be where the line is on the y axis of the graph.
Y = MX + (B)
Edit: Okay assuming the graph is going in the directions by one, meaning 1, 2, 3, or -1, -2, -3, and not any other sequence.
The answer for question will be y = 1/2x -1
A 180 pound weight is supported by two ropes each at 30 degrees, as shown in the figure. Find the tension in each rope.
Answer:
= 41.32N
To find N amount
You find the kg weight then times it by 10 then divide that amount by 1/2
So that 180pounds = 81.6466 x 10kg
x10 = 816.466
81.6466 / 2 = 40.8233
sin(30) = 40.8233/T
T = 40.8233/sin (30) = N / sin(30) = Tension = calculator = -41.3178070464 = 41.32 N

Find the probability that a randomly selected points within a square falls in the blue shaded area (circle)
Answer:
78.8 %
Step-by-step explanation:
From the question,
Area of the square = L²
A = L²
Where L = Length of the square.
From the diagram,
L = 4 in
Therefore,
A = 4²
A = 16 in².
Also,
Area of the circle (A') = πr²
Where r = radius of the circle.
Given: r = 2 in
Therefore,
A' = 22/7(2²)
A = 12.6 in²
Hence,
The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A
Pr = 12.6/16
Pr = 0.7875
Pr(%) = 78.75
Pr(%) = 78.8 %

There is one dot at 3.45. What does that value
represent?
A school administrator claims that the average GPA of
the senior class is 3.53. You think that the average GPA
is greater than that, so you select a random sample of
100 seniors and calculate their average GPA. The
sample mean GPA is 3.70.
Using technology, you simulate selecting 100 SRS of
size n = 100 from a population of seniors for which the
mean GPA is 3.53. This dotplot shows the results.
O In one simulated SRS of 100 students, the average
GPA was = 3.45.
In one simulated SRS of 100 students, the
population mean GPA was u = 3.45.
There is a 1 out of 100 chance that the population
mean GPA is = 3.45.
O A majority of the sample of 100 students had a GPA
of r = 3.45.
Answer: In one simulated SRS of 100 students, the average GPA was x= 3.45

I know from the answer key that the answers are x=
3 \sqrt{10}310
and y=
2 \sqrt{10}210
but I'm not sure how to get there...
Answer:
x = 3/5√10
y = 2√10
Step-by-step explanation:
using the Pythagorean theorem:
y² = 7² - 3² = 49 - 9
y² = 40
y = 2√10
3/4.5 = y/5x
4.5y = 15x
substitute for y:
4.5(2√10) = 15x
15x = 9√10
divide both sides of the equation by 15:
x = (9√10)/15 = 3/5√10

Show how to use substitution or elimination to solve the following system of equations. Write your solution as an ordered pair:
7x + y = 5 , 7x + y = -2
( , )
And please tell me if you used substitution or elimination. TYSM
Answer:
x=.5, y=-5.5
Step-by-step explanation:
7x+y=5, 7x+y=-2
Simplifing 7x+y=5 first
7x+y=5
y=-7x+5
Next, 7x+y=-2
7x+y=-2
y=-7x-2
Plugging in -7x+5 into y
-7x+5=-7x-2
-14x=-7
x=.5
Plugging .5 into y=-7x-2
y=-7(.5)-2
y=-3.5-2
y=-5.5
I used substitution if your couldn't tell
Hope it helps!

Roberto orders 13 quarts of special BBQ sauce. It costs him a total of $206.57. write an equation that can be used to find how much each quart cost. solve the equation
9514 1404 393
Answer:
13c = 206.57
Step-by-step explanation:
If c is the cost of 1 quart of sauce, then 13c is the cost of 13 quarts. We are told that is $206.57, so the equation is ...
13c = $206.57
__
You may be required to leave the dollar sign out of the equation. If you leave it in, then the answer comes with its own units (dollars).
c = $206.57/13 = $15.89
