Answer:
720
Step-by-step explanation:
Out of 80 students the no. of students who sign up=48
So, out of 1200 students 48×1200÷80=720 students sign up.

Answer:
opposite sides of a parallelogram are equal
2x+15=x+15
2x-x=15-15
x=0
Answer:
x = 0
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, that is
ST = RU , substitute values
2x + 15 = x + 15 ( subtract x from both sides )
x + 15 = 15 ( subtract 15 from both sides )
x = 0

Answer:
B. 51
Step-by-step explanation:
In statistics, "range" generally means the difference between the maximum and the minimum. To find the range of these numbers, locate the maximum (54) and the minimum (3) and find their difference:
54 -3 = 51
The range of the numbers is 51.
_____
Additional comment
The range is used for a variety of purposes. In some cases, it can be used to estimate the variance. In other cases, it can be used to choose bin boundaries for a histogram or other chart of values.
This use of the term "range" should not be confused with the idea of the "range" of a function. That is the list (or description) of all function values.

Use what you know about the angle sum theorem for triangles and your algebra skills to solve for x and find the measure of all three angles:
Answer:
2x° = 45°, 3x° = 67.5°
Step-by-step explanation:
Sum of angles in a triangle = 180°
2x+3x+3x=180°
8x=180°
x=22.5°
2x=22.5°x2=45°

Three line segments have measures of 17 units, 11 units and 12 units. Will the segments make a triangle?
Answer:
Yes
Step-by-step explanation:
Yes, they will form a triangle. This is so because when testing for, we use the simple and logical analysis of
Adding up the two shorter sides > the third longest side.
In the example of the question we have here. The two short sides are 11 and 12 respectively. Adding them up together, we have
11 + 12 = 23
And the third longest side to be 17. Now, is 23 greater than 17 or not?
Of course it is, so yes, the sides will form a triangle.

Determine which length form a right triangle
To do this, we make use of Pythagoras theorem where the square of the largest length = the sum of the squares of the other lengths
So:
(1) 12, 35, 37 --- Yes
[tex]37^2 = 35^2 + 12^2[/tex]
[tex]1369 = 1225 + 144[/tex]
[tex]1369 = 1369[/tex]
(2) 16, 30, 34 --- Yes
[tex]34^2 = 16^2 + 30^2[/tex]
[tex]1156 = 256 + 900[/tex]
[tex]1156 = 1156[/tex]
(3) 18, 24, 42 --- No
[tex]42^2 =18^2 + 24^2[/tex]
[tex]1764 =324 + 576[/tex]
[tex]1764 =900[/tex]
[tex]1764 \ne 900[/tex]
(4) 20, 21, 29 -- Yes
[tex]29^2 = 20^2 + 21^2[/tex]
[tex]841= 400 + 441[/tex]
[tex]841= 841[/tex]
Based on the Pythagorean Triple, "12, 35, 37", "16, 30, 34" and "20, 21, 29" will form a right triangle(YES), while "18, 24, 42" will not (NO).
What is the Pythagorean Triple?The Pythagorean triple can be described as any three set of integers representing sides of a right triangle that are solutions to the Pythagorean Theorem, which is given as:
c² = a² + b².
c is the longest side of the right triangle or largest of the set of integers of the Pythagorean triple.
Thus, find out which set of lengths will form a right triangle:
12, 35, 37 will form a right triangle, because:
37² = 35² + 12²
1,369 = 1,369
Also, the rest set of lengths will form a right triangle except, "18, 24, 42".
Thus, based on the Pythagorean Triple, "12, 35, 37", "16, 30, 34" and "20, 21, 29" will form a right triangle(YES), while "18, 24, 42" will not (NO).

Step-by-step explanation:
A is incorrect, as it only shows the 1.5% raise. B is incorrect, since that would be a 15% raise. C and D are incorrect because it's impossible to add a number with a variable to one without a variable. E is correct because it properly adds 100% (the amount he made without the raise) and 1.5% (the raise) together. F is incorrect because again, it adds 15%. G is correct because it is the total amount he makes, with the raise. H is incorrect because again, it adds 15%.

Answer:
24 classes
Step-by-step explanation:
Let
x = number of classes
Devaughn is a member at the local gym = 120 + 5x
Jerome is not a member = 10x
Equate the total cost of both individuals
120 + 5x = 10x
120 = 10x - 5x
120 = 5x
x = 120/5
x = 24 classes
The total cost of Devaughn and the total cost of Jerome will be equal in 24 classes

Given - Jehle and Liam a both solving 0.5÷200.
Jehle says the quotient will be Less than 0.5.
Liam says the quotient would be more than 0.5
To find - Which student is correct ?
Proof -
Given expression is 0.5 ÷ 200
It is equivalent to
[tex]\frac{0.5}{200} = \frac{5}{2000} = \frac{1}{400}[/tex] = 0.0025 < 0.5

Equation is y = -3x + 2
Step-by-step explanation:
(0 , 2) and ( -1 , 5)
m= (y2-y1)/(x2-x1)
m= (5 - 2)/(-1 -0)
m= 3/-1
m= -3
y - y1 = m(x - x1)
y - 2 = -3(x - 0)
y - 2 = -3x + 0
y = -3x + 2
To lease his car, Greg had to pay a $1000 down payment, plus $250 per month. Write an equation that represents the total amount paid. DO NOT PUT ANY SPACES IN YOUR ANSWER.
Answer:
250x+1000
Step-by-step explanation:
The linear equation that represents the total amount paid is 1000 + 250x.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given,
Amount of down payment = $1000
Per month payment = $250
For x number of months = $250x
Total paid = 1000 + 250x
Hence "The linear equation that represents the total amount paid is 1000 + 250x".

The population of fish in an aquarium can be modeled after exponential growth. If there
were originally 3 fish and after 6 weeks there were 31 fish, how many fish would there
be after 14 weeks?
321 fish
698 fish
452 fish
815 fish
Answer:
698 fishes
Step-by-step explanation:
Generally, we can represent an exponential growth function as;
y = a•(1 + r)^t
originally, there were 3 fishes
The original value in this case means a = 3
After 6 weeks, there were 31
31 in this case is y
r is the increase percentage or rate
t is the time
So, we have it that;
31 = 3•(1 + r)^6
31/3 = (1 + r)^6
10.33 = (1 + r)^6
ln 10.33 = 6 ln (1 + r)
ln 10.33/6 = ln (1 + r)
e^0.3892 = (1 + r)
1 + r = 1.476
r = 1.476-1
r = 0.476 or 47.6%
So the growth percentage or rate is 47.6%
For 14 weeks, we simply have the value of t as 14;
So ;
y = 3•(1 + 0.476)^14
y = 3(1.476)^14
y = 698 fishes
what is the answer (2x+1)(3x−4)=0
Answer:
x= 4/3
x= -1/2
Step-by-step explanation:
2x (3x-4) +1(3x-4) = 0
Distribute
6x^-8x +1(3x -4) = 0
Multiply by 1
6x^2 -8x +3x-4=0
Answer:
(2x + 1) ( 3x - 4) = 0
solve by factoring
2x + 1 = 0
2x = -1
divided by 2 on both sides
x = -1/2
3x - 4 = 0
3x = 4
divided by 3 on both sides
x = 4/3
x¹ = -1/2 , x² = 4/3 is the solution
