Answer: 12 for the main square
Step-by-step explanation:
take the 4 and the 3 and multiply it, makes 12. you see how each stair is 6 inches and there is 3 full steps which makes it 1.50 feet. 12 x 1.50 is 18. that makes your main square. I'm sorry but I cant really help you with the steps but that was also confusing to me.
The area of the rectangle is 65 yd^2,and the length of the rectangle is 3 yd less than twice the width. Find the dimensions of the rectangle
Answer: Length = 10cm
Width = 6.5cm
Step-by-step explanation:
Let the width of the rectangle be represented by x.
Therefore, the length of the rectangle will be: = (2 × x) - 3 = 2x - 3
Therefore area of a rectangle = length × width
x(2x - 3) = 65
2x² - 3x = 65
2x² - 3x - 65 = 0
2x² + 10x - 13x - 65 = 0
2x(x + 5) - 13(x + 5) = 0
(2x - 13)(x + 5) = 0
2x - 13 = 0
2x = 13
x = 13/2
x = 6.5
Width = 6.5cm
Length = 2x - 3
= 2(6.5) - 3
= 13 - 3
= 10cm
Therefore, the length of the rectangle is 10cm and the width is 6.5cm.

Find the area of the wrestling mat.
Answer:
804.25
Step-by-step explanation:
The area of a circle = pi(r)^2
Given the diameter, we can find the radius by dividing the diameter in half.
r=16
pi(16)^2 = 804.25
Answer:
803.84 OR 256 pi
Step-by-step explanation:
Ok!
Step 1:
The area of a circle is Pir^2. (Sorry it’s pi r squared, I don’t have the pi symbol or the exponent function on my iPad.)
R is radius. Remember, radius is half the diameter.
32/2=16.
Step 2:
Do 16^2.
You should get 256.
Step 3:
Multiply 256 by Pi. Pi is 3.14. You should get 803.84.
Step 4:
803.84 should be the answer, I THINK (not sure) you can also write your answer as 256 pi. Depends on what your teacher wants. Hope this helps! Next time you can search up how to find the area of a circle, there are lots are tutorials!

If the discriminant of an equation is 10, then the roots are
A) real, rational, and unequal
B) real, irrational, and unequal
C) real, rational, and equal
D) imaginary
Answer:
b

Since the given discriminant is 10, hence the roots will be real, irrational, and unequal
Discriminant of an equation
The discriminant is used to determine the nature of the roots of a quadratic equation. The formula for finding the discriminant is expressed as:
D = b^2 - 4ac

Raylin went to the park with her friends and found a soccer ball. She picked up the soccer ball and kicked it as high as she could. The path of the ball can be represented by h= -16t2 +27t+3
What is the maximum height of the soccer ball? _______________________
How long will it take the ball to reach the ground?
Answer:
The maximum height is: [tex]h(t_{max})=14.39 \: u[/tex]
The ball reaches the ground in 1.79 s.
Step-by-step explanation:
We need to take the derivative and equal to zero to find the time at the maximum height.
[tex]h(t)=-16t^{2} +27t+3[/tex] (1)
[tex]\frac{dh(t)}{dt}=-32t +27=0[/tex]
[tex]t_{max} =\frac{27}{32}[/tex]
[tex]t_{max} =0.84\: u[/tex]
Now, we just need to put t(max) into equation (1) to find h(max)
[tex]h(t_{max})=-16(0.84)^{2} +27(0.84)+3[/tex]
[tex]h(t_{max})=-16(0.84)^{2} +27(0.84)+3[/tex]
[tex]h(t_{max})=14.39 \u[/tex]
If we want to get the time when the ball reaches the ground we just need to equal h(t) to zero.
[tex]0=-16t^{2} +27t+3[/tex]
Let's solve this quadratic equation.
We will get two solutions and we must choose the positive value.
t1 = 1.79 u
t2 = -0.10 u
Therefore, the ball reaches the ground in 1.79 u.

show your work I already have the answer!!
Answer:
(-.5,0) and (-1.5,0)
or b= -.5
and b= -1.5
Step-by-step explanation:
First we want one side of the equation to equal 0
we have
4b²+8b+3=0
using the quadratic formula we have
(-b±√(b²-4*a*c))/2a
(-8±√(8²-4*4*3))/2*4
(-8±√(16))/8
(-8±4)/8
now we evaulate when ± is addition
(-8+4)/8
-4/8
-.5
and evaulate once more when the ± is subtraction
(-8-4)/8
-12/8
-1.5
Therefore the two solutions are (-.5,0) and (-1.5,0)
Answer:
Step-by-step explanation:
step one - Move terms to the left side
(4b^2 + 8b + 7 = 4)
(4b^2 + 8b + 7 - 4 = 0)
step dose - Subtract the numbers
(4b^2 + 8b + 3 = 0)
step три - Use the sum-product pattern
(4b^2 + 6b + 2b + 3 = 0)

¿cuanto suman los angulos interiores de un hexagono? Escribe solo el numero que corresponda a la cantidad, sin el simbolo de grados
Answer:
La suma de los ángulos interiores de un hexágono regular es 720°
Step-by-step explanation:
Asumamos que el hexágono presentado en el enunciado sea regular, el cual es formado por seis triángulos equiláteros, Un ángulo interno del hexágono está formado dos ángulos laterales y vecinos de dos triángulos equiláteros, es decir, dos veces 60°, o sea, 120°. Si el hexágono regular tiene seis ángulos internos de igual medida, entonces la suma de los ángulos interiores es 720°.

Answer:
Graph included as picture
Step-by-step explanation:
To solve this, plot the given points on the graph
Draw a line through them.
Now select two of those values and we'll find the rate of change.
We'll be using (1,-1) and (3,3)
To find rate of change we will be using the formula: [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]y_{2} = 3\\y_{1} =-1\\x_{2} = 3\\x_{1} = 1[/tex]
[tex]\frac{3-(-1)}{3-1} = \frac{4}{2} = 2[/tex]
So the rate of change is 2
You will use this rate of change for your other function because they both have the same rate of change
Since we have the rate of change, we can create the slope intercept form formula: y = mx +b
Just substitute for the variables we know
m = rate of change/slope = 2
b = y-intercept = -3
y = 2x + -3
[If you connected all the points in your graph, that's how you found the y-intercept]
Now we have to create the formula for the second function.
We know it will have that same slope of 2
so we have y = 2x + b
To solve for b we can plug in the values we do have which would be (x,y) of (3,6)
6 = 2(3) + b
Now solve
6 = 6 + b
6 (-6) = 6 (-6) + b
0 = b
b = 0
This mean that the y-intercept will be on (0,0)
Plot that point
Now we finish the formula
y = 2x + 0
Connect the dots, make sure the line continues on both of them past the dots and now you have your graph!
I've included a picture of the graph for your reference. I hope this helps, don't be afraid to reach out with further questions!

Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the histogram is not attached.
However, the solution to your question is to select the interval with the highest frequency
Take for instance, after getting readings from the histogram, yiu have:
1 - 10: 8
11 - 20: 5
21 - 30: 11
31 - 40: 2
And so on.......
Interval 11 - 20 will represent the required interval because it has the highest frequency.
