Answer:
87.5%
Step-by-step explanation:
There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.
The number is students not trying out for football last Thursday is calculated as:
376 students - 47 students
= 329 students
The percent of 8th graders that did not try out for football is calculated as:
329 students/376 students × 100
= 329/376 × 100
= 87.5 %
3sin60°+xcos30°.tan45°=xcot30°
Answer:
x = (6[tex]\sqrt{2}[/tex])/(4[tex]\sqrt{2}[/tex] -3)
Step-by-step explanation:
sin60 degree = [tex]\sqrt{3}[/tex] /2
cos30 degree = 1/2
tan 45 degree = sin45 degree / cos45 degree = ([tex]\sqrt{2}[/tex]/2)/([tex]\sqrt{2}[/tex] /2) = 1
cot 30 degree = cos30 / sin30 = ([tex]\sqrt{3}[/tex] /2)/(1/2) = [tex]\sqrt{3}[/tex]
so, let us plug the above values in the given eqution and solve for x
3([tex]\sqrt{3}[/tex] /2 ) + x(1/2) *1 = x([tex]\sqrt{3}[/tex])
3([tex]\sqrt{3}[/tex] /2 ) = x([tex]\sqrt{3}[/tex]) -x(1/2)
3([tex]\sqrt{3}[/tex] /2 ) = x(([tex]\sqrt{3}[/tex])-(1/2)) (by taking x as a common factor)
3([tex]\sqrt{3}[/tex] /2 ) = x(((2[tex]\sqrt{3}[/tex])-(1))/2)) (making the same common denominator
now devide both sides by (((2[tex]\sqrt{3}[/tex])-(1))/2))
x = 3([tex]\sqrt{3}[/tex] /2 ) / (((2[tex]\sqrt{3}[/tex])-(1))/2))
x = 3([tex]\sqrt{3}[/tex] ) / ((2[tex]\sqrt{3}[/tex])-(1))

3(5+4y)+8-2y how to do this plz
Answer:
[tex]3\left(5+4y\right)+8-2y=10y+23[/tex]
Step-by-step explanation:
Given
As the expression is given by
[tex]3(5+4y)+8-2y[/tex]
To determine
Simplify the expression
Let us simplify the expression
[tex]3(5+4y)+8-2y[/tex]
Expand 3(5 + 4y) = 15 + 12y
[tex]3\left(5+4y\right)+8-2y=15+12y+8-2y[/tex]
grouping like terms
[tex]=12y-2y+15+8[/tex]
[tex]=10y+23[/tex]
Therefore,
[tex]3\left(5+4y\right)+8-2y=10y+23[/tex]

Answer:
244.92 square inches
Step-by-step explanation:
You just have to fill in the formula with the information they gave you.
They gave you the diameter for base circle so you divide that number in half to get the radius which is what you need for the formula represent as "r".
r=3
h=10
and you know pi is 3.14
so just plug in the numbers.
SA=2x3.14x3^2+2x3.14x3x10
SA=6.28x9+6.28x30
SA=56.52+188.4
SA=244.92

Using the formula below, solve when s = 3.
1. A = 6s²
Answer:
54
Step-by-step explanation:
1. A = 6 x 9
A = 54
Hope that helps!
Answer:
heyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
ok i think this is right
Using the SA formula you'll have to substitute in the edge length for s.
SA = 6(312)²
SA = 584064
The surface area is 584,064 feet²

Answer:
so um try The y-intercept represents a starting salary of $ 3,000 for a new employee.
The slope represents an additional $ 2,500 in salary for each additional year of employment.
If the starting salary for a new employee is changed to $35,000 and the salary increase is unchanged, the new equation would be y= 2,500x + 35,000
If the yearly salary increase is changed to $ 2,500 . the new equation would be y= 3,000

Step-by-step explanation:
To find the missing leg, we need to use a^2 + b^2 = c^2.
Let's call the missing leg a, and then substitute the numbers the other numbers
a^2 + 12^2 = 13^2
Simplify
a^2 + 144 = 169
To solve, subtract 144 from both sides (169-144)
a^2 = 25
This means that a squared is 25; to find a, we need to find the square root of 25.
a = 5
Your answer is 5.
Answer:
5m
Step-by-step explanation:
set it up
[tex]12^{2}[/tex]+[tex]a^{2}[/tex]=[tex]13^{2}[/tex]
do what you know
equation becomes: 144+[tex]a^{2}[/tex]=169
subtract both sides by 144
equation becomes [tex]a{2}[/tex]=25
square root both sides
equation becomes: a=5

y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y
Answer: x = 1 and y = -1
Step-by-step explanation:
Since both equations are equal to y, that means the equations are both equal to each other
5x - 6 = -4x + 3
Solve for x how you would traditionally do it with any other one-variable equation
9x = 9
x = 1
Plug the now known x value into either equation and you will get your y value.
5(1) - 6 = -1
-4(1) + 3 = -1
anyone think they could help me with this ???
Answer:
12°
Step-by-step explanation:
As we can see the triangles are congruent so
< F = < C ( being corresponding angles of congruent triangle)
< C = 29
Now
<A +<B + <C = 180° { being sum of angles of triangle }
5x + 1 + 90 + 29 = 180°
5x = 180° - 120°
5x = 60°
x = 12°
What is the domain of the function?
X+6
f(x)=(x-7)(x+5)
A all real numbers except 7
Ball real numbers except 5 and -7
Call real numbers except -5 and 7
D all real numbers
The required domain of the function is all real numbers except -5 and 7. Option C is correct.
Given that,
f(x) = (x + 6) /[(x-7)(x+5)]
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
Given function,
f(x) = (x + 6) /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.
Thus, the required domain of the function is all real numbers except -5 and 7. Option C is correct.

ILL MARK YOU BRAINLIEST To join a health club, a person must pay a $75 one-time fee plus a charge of $30 per month. This situation can be presented by an equation of the form y=mx+b, where x = the fire in months and ythe
total cost in dollars. What is the value of b in this equation?
Answer: b=75
Step-by-step explanation: Given that the health club charges $30 per month, we know that this is the "m" varible. We know this because the total value changes as the value of x changes. The value of b would therefore be $75 dollars because it is a constant and a one time fee. The person joining the health club pays an amount of money per month, as well as an initial charge of $75.
Hope that helps!
