B 7.07
C [tex]\sqrt{50}[/tex]
Step-by-step explanation:
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
[tex]5^{2}[/tex] + [tex]5^{2}[/tex] = [tex]c^{2}[/tex]
25 + 25 = [tex]c^{2}[/tex]
50 = [tex]c^{2}[/tex]
[tex]\sqrt{50}[/tex] = [tex]\sqrt{c^{2} }[/tex]
[tex]\sqrt{50}[/tex] = c This is the exact answer. [tex]\sqrt{50}[/tex] is an irrational number. This means that it never terminates or repeats in the decimal form.

Answer(s):
[tex]5\sqrt{2}[/tex] and [tex]7.07[/tex]
Step-by-step explanation:
substitute a=5 and b= 5 into Pythagorean Theorem:
[tex]a^2+b^2=c^2\\(5)^{2}+ (5)^{2} = c^2[/tex]
Simplify:
[tex]25+25=c^{2}[/tex]
[tex]50=c^{2}[/tex]
square root of c^2 and 50
[tex]\sqrt{50} =\sqrt{c^2} \\\\\sqrt{50} =c[/tex]
Use prime factorization to reduce [tex]\sqrt{50}[/tex] to [tex]5\sqrt{2}[/tex]

tickets for a baseball game are $69 for main level seats and $39 for terrace level seats. a group of fifteen friends went to the game and spent a total of $735 for the tickets. how many of main level and how many terrace level tickets did they buy?
Answers
Tickets for a ball game are $69 for Primary Level seats and $39 for Porch Level seats. A total of $804 was spent on the tickets by a group of 16 friends who attended the game.
How many tickets were purchased for the Main Level and the Terrace Level?
No. of tickets for the Main Level = X
No. total price = 804 = 39(16 - X) + 69X = 624 - 39X + 69X = 624 + 30X 30X = 804 - 624 = 180 X = 180/30 = 6
No. of Terrace Level Tickets = 16 - X
Main Level Tickets Prace = 69X
Terrace Level Tickets Prace = 39X
Total Price = 804 = 39(16 - X) + 69X = 624 - 39X + 69X =of tickets for the Main Level, X = 6
No. of tickets for the Terrace Level: 16 - X = 16 - 6 = 10 Check:39x10 + 69x6 = 390 + 414 = 804

Answers
Answer:
-2 ( 12x - 1 )
Step-by-step explanation:
1) Simplify the equation
To simplify the equation, we have to get rid of any brackets. To do this multiply the term to left of it with everything inside the bracket
-2 x 4 = -8-2 x 12x = -24xNow we can plug these numbers into our equation
2) Collect like terms
The equation we are left with from the previous step would be 10-8-24x
The terms that are similar are 10 and -8.
To collect like terms simplify the terms down to one term
10 - 8 = 23) Find common factor and simplify
What we are left with from the previous step is -24x+2
To find the common factor you have to find a number that goes it both numbers which for 2 and 24 would be 12.
-24x ÷ 2 = -12x2 ÷ 2 = 1We are left with -2 ( 12x - 1 )Hope this helps, have a great day!

What is linear equation?An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression. Linear equations are the equations of degree 1. It is the equation for the straight line. The solutions of linear equations will generate values, which when substituted for the unknown values, make the equation true. In the case of one variable, there is only one solution. For example, the equation x + 3 = 0 has only one solution as x = -2.
the total amount of money Hannah repaid is $225+$43×w, where w is the number of weeks to repay $43.
therefore $999= $225+$43w
$43w=$ (999+225)
$43w= $1224
divide both side by $43
w= $1224/$43
w= 18 weeks
therefore it will take Hannah 18weeks to repay the money.

A recording studio charges musicians an initial fee of $ 100 to record and album. Studio time also coasts an additional $75 per hour
Write a slope intercept form equitation to model this situation
Answers
The linear model that represents the total cost of recording is f(x) = 75x + 50.
The initial fee is $50 for recording an album.
There is an additional cost per hour i.e. $75.
number of hours = x
Now based on the above information, the linear model should be f(x)=75x+50
Here 50 represent the initial fee i.e. equivalent to y-intercept
And, 75 represent the slope
Therefore we can conclude that the linear model that represents the total cost of recording is f(x) = 75x + 50.

Dr. Ellison says that the equation y = -3x + 7 has a solution f(2) = 5/3. Is Dr. Ellison right or wrong?
Answers
Dr. Ellison's equation that f(2) = 5/3 is wrong
How to determine if the doctor is right or wrong?From the question, we have the following equation that can be used in our computation:
y = -3x + 7
This equation can be expressed as a function
So, we have
f(x) = -3x + 7
In Dr. Ellison's equation, we have
f(2) = 5/3
This means that
x = 2
So, we have
f(2) = -3 * 2 + 7
Evaluate
f(2) = 1
The calculated value is different from Dr. Ellison's equation
Hence, the solution is wrong

(2) {5,6,7}
(3) {5, 6,9}

Answers
For the given function h(x) = x² +5 ,the domain of the function h(x) maps by the set { -2, -1, 0, 1, 2 } then the range of the function h(x) is given by the set { 5, 6, 9 } .
As given in the question,
Given function is equal to :
h(x) = x² +5
Domain of the function h(x) = x² +5 maps by the set { -2, -1, 0, 1, 2 }
Range of the function h(x) = x² +5 is represented by the set as follow :
Substitute the value x = -2, -1, 0, 1, 2 in the function h(x) = x² +5 we get,
h(-2) = (-2)² + 5
= 9
h(-1) = (-1)² + 5
= 6
h(0) = (0)² + 5
= 5
h(1) = (1)² + 5
= 6
h(2) = (2)² + 5
= 9
Range of the function is represented by the set : { 5, 6, 9 }
Therefore, for the given function h(x) = x² +5 ,the domain of the function h(x) maps by the set { -2, -1, 0, 1, 2 } then the range of the function h(x) is given by the set { 5, 6, 9 }.

Answers
For the given fees charged by two fitness clubs , number of months required by two fitness clubs to pay the same total amount is equal to 10 months.
As given in the question,
Number of fitness club = 2
Let 'x' represents the number of months
Charges for a month membership charged by Mike's Fitness center is equal to $30.
Charges for a month membership charged by All-Day Fitness club is equal to $22 plus $80 initiation fee.
Required equation when two clubs have same amount of charges is given by:
30x = 22x + 80
⇒ 30x -22x = 80
⇒ 8x = 80
⇒ x = 10 months
Therefore, number of months required by two fitness clubs to pay the same total amount is equal to 10 months.

Since both lines are parallel, you can assume that Angle 6 plus Angle 7 are a linear pair. Angle 1 corresponds to Angle 5 by the corresponding parts. Angle 5 is congruent to Angle 7 by Vertical angles so therefore Angle 7 is 102. Since Angle 6 + Angle 7 equal 180 degrees, you can put the equation like this,

a box is given a sudden push up a ramp. friction between the box and the ramp is not negligible. which of the following diagrams best represents the directions of the actual forces acting on the box as it moves upward after the push?
Answers
For a box given a sudden push up a ramp and the friction between the box and the ramp is not negligible, the diagrams which best represent the directions of the actual forces acting on the box as it moves upward after the push is Option A.
Friction refers to the force of resistance in the relative motion of solid surfaces in contact and sliding or rolling against each other. Frictional forces are affected by the surface texture and the amount of force impelling them together and the angle and position of the object. The actual forces acting on the box will be the normal force (always perpendicular to the surface), weight force (acting downward) and frictional force (acting opposite to the direction of push).
