Answer:
Mrs. Foster's class had the most students in class that Friday
Step-by-step explanation:
Mr Lopez - 92.5%
Mrs Foster - 19/20
Mr Kelly - 0.9
Let's say that there were 40 students in class
92.5% of 40 would be 37
So
Mr Lopez's Class had 37 students.
19/20 of 40 would be 38
So
Mrs Foster's Class had 38 students
0.9 of 40 would be 36
So
Ms Kelly's class had 36 students
Therefore, from looking at this, the answer would be Mrs Foster's Class

The diameter of a circle is 26 inches. What is the circle's area?
Use 3.14 for .
i will give brainliest
Answer:
530.66 inches²
Step-by-step explanation:
How do we find the radius?
The radius if 1/2 of the diameter, so 26/2 = 13 inchesHow do we find the area of a circle?
The area of a circle is πr², where r = radius. We are given the radius as 13 inches, and pi is approximated to 3.14.Solving
[tex]3.14*13^2[/tex] [tex]3.14*169[/tex] [tex]530.66[/tex]Therefore, the answer is 530.66 inches².
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Solution:
We know that:
Diameter = 26 in.Radius = Diameter/2Area of circle = πr²Finding the radius of the circle.
Radius = Diameter/2=> Radius = 26/2 = 13 in.Finding the area of the circle.
Area of circle = πr²=> Area of circle = (3.14)(13²)=> Area of circle = 3.14 x 169=> Area of circle = 530.66 in²Does this graph show a function??
Answer:
yes
Step-by-step explanation:
the function does not cross the same point of x twice.
Answer:
B.) Yes; The graph passes the vertical line test!
Step-by-step explanation:
This graph does indeed show a function! A parabola, it looks like!
A function on a graph is determined when the function passes the vertical line test, meaning no matter where you go on the function, a specific vertical line will only pass through one point!

What are the values of s and t?
Answer:
s=144
t=36
Step-by-step explanation:
you minus 180 from 36 and you get 144 for s
then you minus 180 from 144 to get t
Answer:
t = 36°
s = 108°
Step-by-step explanation:
FE and DE are congruent. This means that triangle ΔDEF is isosceles.
Base angles (∠EFD and ∠EDF) in isosceles triangles are congurent.
∠EFD is 36°. This means that ∠t is also 36°
The measure of all the angles in a triangle is 180°
[tex]36+36+x=180\\72+x=180\\x=108[/tex]
∠s = 108°
If a(x)= 2x -4 and b(x) = x + 2, which of the following expressions produces a quadratic function? O (ab)(x) O(a/b)(x) O(a-b)(x) O(a+ b)(x)
Answer:
(ab)(x)Step-by-step explanation:
Given are 2 linear functions
Only their product can produce a quadratic function
So the correct option is
(ab)(x)What is the domain of Ax) = 4*?
O A. All nonnegative real numbers
O B. All real numbers greater than 4
O C. All real numbers
O D. All real numbers greater than or equal to 4
Answer: all real numbers!! <3
Step-by-step explanation:
i need help asap, pls help!!
Answer:
see below
Step-by-step explanation:
Since the triangles are congruent
<A = <X
< B = < Y
<C = < Z
That means B = Y = 90
And C = Z = 37
The sum of the angles of a triangle are 180
A+ B+ C = 180
A + 90+37 = 180
A +127 = 180
A = 180-127
A =53
A = X = 53
We also know
AB = XY
BC = YZ
AC = XZ
AB = 3 so XY =3
YZ = 4 so BC =4
XZ = 5 so AC = 5

Write the equation of the line in slope-intercept form that passes through the following points.
(4, 7) and (1, -2)
Answer:
y= 3x - 5
Step-by-step explanation:
coordinates given: (4,7) & (1, -2)
to find m (slope) = rise/run = (y2-y1) /(x2-x1)
= ( -2-7) / (1 - 4)
= -9/-3
= 3
therefore, y=3x + b
to find b:
taken coordinate: (4,7)
y=3x + b
7=3 (4) + b
7= 12 + b
7-12 = b
-5 = b
(*the value of b will be same even if we take the other coordinate)
therefore, y = 3x -5
A metronome uses an inverted pendulum rod to control tempo. A weight can be slid up the pendulum rod to decrease tempo, or down the pendulum rod to increase tempo. A second fixed weight is hidden inside the metronome at the base of the pendulum. The longer the distance between the two weights, the slower the tempo. This equation is used to calculate the frequency of the metronome pendulum:
[tex]f = \frac{ \sqrt{ \frac{g}{l} } }{2\pi} [/tex]
Each time the metronome's pendulum completes one back and forth cycle, it produces two ticks or beats. To calibrate the metronome for beats per minute (bpm) the manufacturer needs to know the length of the pendulum for various tempos. Solve
[tex]f = \frac{ \sqrt{ \frac{g}{l} } }{2\pi} [/tex]
for L.
Answer:
Part 1
Multiply both sides by 2π
2πf = √(g/L)
Square both sides
4π²f²= g/L
Invert both sides
1/(4π²f²) = L/g
Multiply both side by g
g/(4π²f²) = L
We usually write an equation with the subject (L) n the left
L = g/(4π²f²)
________________________
Part 2
Using the above equation with the given values:
L = g/(4π²f²)
. .= 9.8 / (4π² x 1.6²)
. .= 0.097m (= 9.7cm)
________________________
By the way, where it says
“f=1.6 then there are 2 beats a second, or 192 beats per minute (bpm).”
this should say
“f=1.6 then there are 3.2 beats a second, or 192 beats per minute (bpm)”
Step-by-step explanation:
The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm)
What is equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Here, we have,
Part 1
Multiply both sides by 2π
2πf = √(g/L)
Square both sides
4π²f²= g/L
Invert both sides
1/(4π²f²) = L/g
Multiply both side by g
g/(4π²f²) = L
We usually write an equation with the subject (L) n the left
L = g/(4π²f²)
________________________
Part 2
Using the above equation with the given values:
L = g/(4π²f²)
L.= 9.8 / (4π² x 1.6²)
L.= 0.097m (= 9.7cm)
Hence, The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm).

. Find the slope of the line through the points (-5, 86) and (95, 16).
The slope's equation is:
⇒ [tex]\frac{y2-y1}{x2-x1}[/tex]
Since the two points are (-5,86) and (95,16)
⇒[tex]slope = \frac{16-86}{95--5} =-\frac{70}{100} =-\frac{7}{10}[/tex]
Thus the slope is -7/10.
