Given. That 2x+1=32, find the value of x
Answer:
x=15.5
Step-by-step explanation:
2x+1=32
2x=32-1
2x=31
x=15.5
Answer:
x = [tex]\frac{31}{2}[/tex]
Step-by-step explanation:
Given
2x + 1 = 32 ( subtract 1 from both sides )
2x = 31 ( divide both sides by 2 )
x = [tex]\frac{31}{2}[/tex]
There are 40 students in the 5th grade. 22 of them play soccer. What percentage of the students in the class do NOT play soccer? Please show work i need help
Step-by-step explanation:
If there are 40 kids and 22 of them play soccer that leaves you to subtract 22 from 40 which gives you 18. After that, you put the rest of the 18 students over a total of 40 and divide to get the decimal .45 and if you convert that into a percent you are left with 45%.
1. 40-22=18
2.18/40=.45
3.45=45%

what type of function best models the data in the graph?
ANSWER: quadratic
which quadratic equation best models the data in the graph?
ANSWER: y=0.433x^2
ANSWER: quadratic
which quadratic equation best models the data in the graph?
ANSWER: y=0.433x^2
The function that models here is quadratic.
We know,
The curve-shaped graph of a quadratic function is known as a parabola. The vertex of a parabola is one of its focal points. On the graph, it is either the highest or lowest point.
As, The graph shows that the value of x and value of y both increase.
Also, the value of y increases almost as the value of x.
Here the graph represent the Quadratic Equation.

x - (2x + 1) = 8 - (3x + 2)
Answer:
x=7/2
Step-by-step explanation:
Answer:
x=7/2
Step-by-step explanation:
x-(2x+1)=8-(3x+2)
x-2x-1=8-3x-2
-x-1=6-3x
+x on both sides
-1=6-2x
-6 on both sides
-7=-2x
7=2x
÷2 on both sides
7/2=x

A cube root function has a turning point located at (-2,3). Write an equation that could represent this function
Answer:
f(x) = A*∛(x + 2) + 3
Step-by-step explanation:
Suppose a generic cube as:
f(x) = A*∛(x - b) + C
We will have a turning point at the x value:
x = b
Then if we have a turning point at (-2, 3)
This means that the turning point is at x = -2 and y = 3
Then b = -2
And our cube root function will be something like:
f(x) = A*∛(x - (-2)) + C
f(x) = A*∛(x + 2) + C
And we know that f(-2) = 3
then:
f(-2) = A*∛(-2 + 2) + C = 3
f(-2) = A*∛(0) + C = 3
= C = 3
Then the general equation will be something like:
f(x) = A*∛(x + 2) + 3

A square-based rectangular aquarium is filled with water. The side length of the
base is 40 cm. The height of the aquarium is 50 cm. The height of the water is
equal to half the height of the aquarium. A solid cube with side length 20 cm is
then thrown into the aquarium and sinks to the bottom.
Does the water level now reach the top of the tank? If not, how far below the top
of the tank does the water reach?
Answer:
From bottom = 30 cm
Below top = 20 cm
Step-by-step explanation:
Length & breadth of the aquarium = 40cm(as it is square)
Volume of aquarium = l x b x h
volume of aquarium = 40 x 40 x 50 = 80000 cm³
Volume of water = ½ half of aquarium
Volume of water = ½ x 80000 = 40000 cm³
Volume of the solid cube = a³ = (20cm)³ = 8000cm³
Surely, 40000>>>8000, level doesnt reach the top of the tank.
Volume acquired = 40000+8000=48000 cm³
Now, let it has reached reached a height h from the ground(bottom).
Volume = 48000 => lx b x h = 48000
=> 40 x 40 x h = 48000
=> h = 30 cm
The height at which water has reached is 30 cm(from bottom).
Thus, below the top it has reached = total height - 30 cm = 50 - 30 = 20 cm

Find the one of the following sets of side lenghts could represent a right triangle
Answer:
B
Step-by-step explanation:
Using the pythagorean theorem A^2 + B^2 = C^2 the only numbers that work are those in choice B. 8 short leg, 15 long leg, 17 hypotenuse.
8^2 + 15^2 = 17^2 = 64 +225=289 = 289=289 therefor proving these set of numbers are a right triangle.

Help me
Answer:
30
Step-by-step explanation:
i believe that the 13 is there to throw you off. anyway to solve just do 5•12=60
60÷2=30 so 30 is area of triangle
area of triangle =1/2×base×height
area of triangle=1/2×12×5
area of triangle=30 unit²

Alexandria has $50 that their parents gave them to go to a soccer game with. The game cost $22 to get in, how much more money can they spend?
I think I understand what you mean. If Alex got $50 and already spent 22 to get into the actual game, then they would have $28 after getting into the actual game.
So $28 dollars.
(Hope that's what you meant.)
