Answer:
Step-by-step explanation:
The total amount of students is 240
240(50%) = 120 > 60 so, the first true or false is False
240(5%) = 12 = 12 so, the the second true or false is True
240(60%) = 144 = 144 so, the third true or false is True
132 + 12 = 144

A stock loses half its value each week. If the stock started at $125, what is it worth after 4 weeks?
Answer: 7.81
The formula is
y = 125* (1/2)^4
y = 125 / 16
y = 7.81
So at the end of the 4th week, the stock is worth only 7.81 dollars.
If that is not the motive and the first week doesn't count then the formula changes to...
y = 125 * (1/2)^(n-1)
y = 125 * (1/2)^3
y = 15.625 could be the other answer if you looked at it in that perspective
However, I would go with 7.81 as the answer.
Hope I helped :)

use graph to answer question
Answer:
cos(θ) = 3/5
Step-by-step explanation:
We can think of this situation as a triangle rectangle (you can see it in the image below).
Here, we have a triangle rectangle with an angle θ, such that the adjacent cathetus to θ is 3 units long, and the cathetus opposite to θ is 4 units long.
Here we want to find cos(θ).
You should remember:
cos(θ) = (adjacent cathetus)/(hypotenuse)
We already know that the adjacent cathetus is equal to 3.
And for the hypotenuse, we can use the Pythagorean's theorem, which says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, this is:
3^2 + 4^2 = H^2
We can solve this for H, to get:
H = √( 3^2 + 4^2) = √(9 + 16) = √25 = 5
The hypotenuse is 5 units long.
Then we have:
cos(θ) = (adjacent cathetus)/(hypotenuse)
cos(θ) = 3/5

Alyssa opened a bank account that earns 1.5% simple interest. Over 4 years, she earned $72 in interest. How much money did
she initially deposit into the bank account?
Answer:
1200
Step-by-step explanation:
72/4=$18 interest each year
amount x interest rate = interest
amount x .015 = 18
amount = 18/.015
amount = 1200
Triangle ABC is given by the points A(3, 2), B (4, 4), and C(5, 1). Select True or False for each statement.
Answer:
C. The perimeter of ΔABC is 7.6 units.
Step-by-step explanation:
Triangle ABC is given by the points A(3, 2), B(4, 4), and C(5, 1). Determine if each statement is True or False.
A. The perimeter of ΔABC is 9.9 units.
B. ΔABC is an equilateral triangle.
C. The perimeter of ΔABC is 7.6 units.
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, acute, obtuse and right angled triangle.
The distance between two points (x₁, y₁) and (x₂, y₂) in the coordinate plane is:
[tex]Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Given the vertices of triangle ABC as A(3, 2), B(4, 4), and C(5, 1). Therefore we have to calculate the side lengths of the triangle:
[tex]AB=\sqrt{(4-3)^2+(4-2)^2}=\sqrt{1+4}=\sqrt{5} \\\\AC=\sqrt{(5-3)^2+*(1-2)^2}=\sqrt{4+1}=\sqrt{5} \\\\BC=\sqrt{(5-4)^2+(1-4)^2}=\sqrt{1+9}=\sqrt{10}[/tex]
1) Perimeter of the triangle = AB + AC + BC = √5 + √5 + √10 = 7.6 units
2) Since only two sides of the triangle are equal (i.e. AB = AC), hence the triangle is an isosceles triangle.

An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded. Which could be the number of scoops sold if they rounded to the nearest thousand? Choose all answers that apply
Answer:
B - 12,111
C - 11,589
Step-by-step explanation:
Here are the options
A - 10, 999
B - 12,111
C - 11,589
In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit
Rounding off 10,999 to the nearest thousand is 11,000
the hundred figure is greater than 5, so one is added to the thousand figure. The
Rounding off 12,111 to the nearest thousand is 12,000
the hundred figure is less than 5, so zero is added to the thousand figure.
Rounding off 11,589 to the nearest thousand is 12,000
the hundred figure is equal to 5, so one is added to the thousand figure.

How can I solve for y and what is the answer
Answer:
y = 38
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the angles in the large outer triangle, then
x + 46 + 78 = 180
x + 124 = 180 ( subtract 124 from both sides )
x = 56
Consider the 3 angles in the smaller inner triangle, then
y + x + 86 = 180 , that is
y + 56 + 86 = 180
y + 142 = 180 ( subtract 142 from both sides )
y = 38
Darren has a wooden board that is Three-fifths of a meter long. He cuts the board into 3 equal parts. How long is each section of board?
Answer:
Each section of the board is 1/3 or 0.334(0.333333333333) of a meter
Step-by-step explanation:
3/5 divided by 3 is the equation we have to do.
3/5 divided by 3 is also equal to 3/5 times the reciprocal of 3 or 1/3
3/5 * 1/3
3*1 = 3
5*3 = 15
3/15 which can simplify to 1/3. (divide numerator and denominator by 3.)
Each section of the board is 1/3 or 0.334(0.333333333333) of a meter

what is the median of the following strings of value 34,63,28,7,15,8,92,37,85,3
Answer:
3,7,8,15, 28,34, 37,63,85,92
median is 28+34=62 divide 62 by 2= 31
31 is the answer
Step-by-step explanation:
put the numbers in ascending or descending order and find the number middle number. if you need to you can take the average of the two numbers in the middle if you don't have a single middle number.
Answer:
The median is equal to 31.
Step-by-step explanation:
In order to find the median we first have to arrange the values in order from least to greatest, so we get...
3, 7, 8, 15, 28, 34, 37, 63, 85, 92
Since, there is an even amount of values, in order to find the median we have to take the two middle numbers and find their average (if there would be an odd number of values the middle number would be the median). The middle numbers are 28 and 34, and their average is...
(28 + 34) / 2 = 62 / 2 = 31
Therefore, the median is equal to 31.

What is the value of x?
x = [ ? ]
Answer:
Step-by-step explanation:
The tangent to the angle makes an angle of 90° with the radius.
The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.
By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore
x = 60-30 = 30°.
