Answer:
5^2+h^2=12^2, the answer would be ~10.97 ft.
Step-by-step explanation:
I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.
Pythagorean theorem is :
a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.
Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.

Answer:
45
Step-by-step explanation:
each bracelet takes 15 min
15*3=45
1 hour = 60 minutes..
In 1 hour she makes 4
In 2 hours (120 minutes) she makes 8
So in each hour she makes 4 ( 8 /2 = 4)
So In 3 hours she will make 3 x 4 = 12 bracelets

Step-by-step explanation:
Jon is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by h(t)=5+25t-16t^2, where t is the time in seconds.
a) How much time will pass before Jon hits the ball? (round to the nearest tenth of a second)
b) What is the time in which the maximum height the ball attains? ( to the nearest hundredth of a second)
Answer: A= 1.60 sec
And I am not sure if B is correct, but I got 14.77 ft.
Step-by-step explanation:
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jon who is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by -
h(t) = 5 + 25t - 16t²
where [t] is the time in seconds.
[A] -
At h = 4ft, we can write -
4 = 5 + 25t - 16t²
- 16t² + 25t + 1 = 0
On solving, we get -
t = 1.602 seconds
[B] -
We have -
h(t) = 5 + 25t - 16t²
For maximum height -
dh/dt = 0
d/dt(5 + 25t - 16t²) = 0
0 + 25 - 32t = 0
32t = 25
t = 25/32
t = 0.79 seconds
Therefore -
t = 1.602 seconds will pass before Jon hits the ball.At t = 0.79 seconds the ball attains maximum height.To solve more questions on Equation Modelling, visit the link below -

Can someone help me
Answer:
50%
Step-by-step explanation:
because that say each square represent a Whole that is 100%
and each triangle represents the 1/2 Of a whole that is 50%
The percent is 50% because as you see that it is only shading half of that square!
We can't give you the direct answer but note: Well we cannot give the direct answers, this a a big part in the question, you can see that it gives 50% but there is also the other whole sqaure :)

Which equation can be used to solve for x in the parallelogram below?
A) 3x-12=6x+12
B) (7x-8)+(6x+12)=90
C) 3x-12=2x+8
D) (7x-8)+(6x+12)=180
Answer:
B. (3x - 12)° = (2x + 8)°
Step-by-step explanation:
This equation can be used to solve x.
3x - 12 = 2x + 8
3x - 2x = 12 + 8
x = 20°
-------------------------------------------------------------------
Verification:
3(20) - 12 = 2(20) + 8
60 - 12 = 40 + 8
48° = 48°

Which table represents a quadratic function?
Answer:
D
Step-by-step explanation:
A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

The table shows data for a car stopping on a wet road. Stopping distance formula [tex]d(v)=\frac{2.15v^{2} }{64.4f}[/tex]
Determine the value of f, rounded to the nearest hundredth.
Answer:
0.35
the next one is d(v) = 2.15v^2 / 22.54
Step-by-step explanation:
i just did this assignment. also thanks to the answer above me :)
We have that the value of f, rounded to the nearest hundredth.
f_1=0.02
f_2=0.009
f_3=0.009
From the question we are told that
d(v)= \frac{2.15v^2}{64.4f}
Generally the equation for the f is mathematically given as
f= \frac{2.15v^2}{64.4*d(v)}
Therefore
For v=20 and f=38
f= \frac{2.15(20)^2}{64.4*(38)(20)}
f=0.02
For v=30 and f=86
f=\frac{2.15(30)^2}{64.4*(86)(30)}
f=0.01
For v=40 and f=153
f=\frac{2.15(40)^2}{64.4*(153)(40)}
f=0.009

Complete the statements about the system of linear equations represented by the tables.
The equation representing the left table is
.
The equation representing the right table is
.
The solution to the system of equations is
Answer:
The equation representing the left table is:
y = 1.5x – 6
The equation representing the right table is:
y = –4x + 6.1
The solution to the system of equations is:
(2.2, –2.7)
Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The first table is
x y
0 -6
1 -4.5
2 -3
3 -1.5
Slope = -4.5+6/1
=1.5
Now let us find y intercept
-6=1.5(0)+b
-6=b
So the equation representing the left table is y=1.5x-6
Now let us find second table
x y
0 6.1
1 2.1
2 -1.9
3 -5.9
m=2.1-6.1/1=-4
Now y intercept
2.1=-4+b
b=2.1+4
b=6.1
Equation representing the right table is y=-4x+6.1
Now equate two equations
1.5x-6=-4x+6.1
1.5x+4x=6.1+6
5.5x=12.1
x=12.1/5.5
x=2.2
and y=-4(2.2)+6.1
y=-8.8+6.1
y=-2.7
Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
