Answer:
4212 square feet.
Step-by-step explanation:
If the blueprint's scale is 1 inch : 9 feet.
Square both sides
(1in)² = (9ft)²
1in² = 81ft²
Given the gym's area as 52 square inches, hence;
52in² = x
Divide both expressions
1/52 = 81/x
x = 52 * 81
x = 4212ft²
Hence the area of the actual gym is 4212 square feet.

J. If two lines are parallel, what does this mean?
K. If you are told that two lines are perpendicular, what does this mean?
L. What are the similarities between parallel lines?
M. What is the relationship between two lines that are perpendicular?
Answer:
A) y=mx+b
B) The slope of a line is a number that describes both the direction and the steepness of the line. The slope of the line is either increasing, decreasing, horizontal or vertical.
C) m= rise/run =y2-y1/x2-x1
D) A rate of change describes how one quanity changes with respect to the other. The rate of Change for a line is the slope, the rise over run, or the change in y over the change in x.
E)The y-intercept of the line is the value of y where the line crosses the y-axis.
F)The x-intercept of the line is the value of x where the line crosses the x-axis.
G) The point-slope formula is y-y1=m(x-x1)
H)HOY stands for Horizontal line, slope =0, their equations are in the form y= a constant
I)VUX stands for Vertical line, slope =Undefined, their equations are in the form x= a constant
J)If two lines are parallel, this means that the slopes are the same and the y-intercept are different.
K) The slope of perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees
L) The similarities between parallel lines are they have the same steepness, or same angle from the horizontal. Since they have the same steepness they have the same slope.
M)The relationship between two lines that are perpendicular intersect at right angles. they are coplanar lines

Consider the following equation.
[tex]5^{-x}[/tex]+7=2x+4
Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a starting point.
a. x=[tex]\frac{7}{4}[/tex]
b. x=[tex]\frac{27}{16}[/tex]
c. x=[tex]\frac{13}{8}[/tex]
d. x=[tex]\frac{25}{16}[/tex]
Answer:
C
Step-by-step explanation:
I think
The solution to the equation above using three iterations of successive approximation is x = 25/16
What is an equation?An equation is an expression that is represented by the equality or equal to sign i.e "="
The equation is given as:
[tex]5^{-x} + 7 =2x + 4[/tex]
Equate to 0
[tex]5^{-x} + 7 -2x - 4 = 0[/tex]
Express as a function
[tex]f(x) = 5^{-x} + 7 -2x - 4[/tex]
The equation has a solution when f(x) = 0.
From the graph, we have:
x = 1.5
So, we have:
[tex]f(1.5) = 5^{-1.5} + 7 -2*1.5 - 4[/tex]
Evaluate
f(1.5) = 0.089
Set x to 1.52 to determine a closer value of f(x) to 0.
[tex]f(1.52) = 5^{-1.52} + 7 -2*1.52 - 4[/tex]
Evaluate
f(1.52) = 0.047
Set x to 1.54 to determine a closer value of f(x) to 0.
[tex]f(1.54) = 5^{-1.54} + 7 -2*1.54 - 4[/tex]
Evaluate
f(1.54) = 0.004
Notice that 0.004 is closer to 0 than 0.047 and 0.089
From the list of options, the closest value to 1.54 is 25/16
Hence, the solution to the equation above using three iterations of successive approximation is x = 25/16

find two numbers if their sum is 3/5 and their difference is 7 1/5
Answer:
A = 3 + 9/10
B = -(3 + 3/10)
Step-by-step explanation:
We have two numbers, A and B, such that:
A + B = 3/5
A - B = 7 + 1/5
To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:
A = 3/5 - B
Now we can replace this in the other equation:
A - B = 7 + 1/5
(3/5 - B) - B = 7 + 1/5
3/5 - 2*B = 7 + 1/5
-2*B = 7 + 1/5 - 3/5
-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5
B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)
Now that we know the value of B, we can use the equation
A = 3/5 - B
To find the value of A:
A = 3/5 - ( -(3 + 3/10))
A = 3/5 + (3 + 3/10) = 6/10 + 3 + 3/10 = 3 + 9/10
The numbers are:
A = 3 + 9/10
B = -(3 + 3/10)

What is the slope of the line that passes through the points (5, 1) and (2, -7)?
Answer:
8/3
Step-by-step explanation:
We need to find the slope of the line that passes through points , (5,1) and (2,-7) . We can find the slope as ,
=> m = y₁ - y₂/ x ₁ - x ₂
=> m = -7 - 1 / 2 - 5
=> m = -8/-3
=> m = 8/3
Hence the slope of the line is 8/3 .NEED HELP ASAP!!

10) Calculate angle u, v and w
A
Y
с
88
68
Answer:
u = 24, v = 92, and w = 184
Step-by-step explanation:
According to circle theorem, we have;
∠ACD = ∠ABD = 88° by angle inscribed in a circle and also subtending the same chord
∠DOA = 2 × ∠ABD by angle subtended at the center = 2 × Angle subtended at the circumference
∴ ∠DOA = 2 × ∠ABD = 2 × 88° = 176°
w° + ∠DOA = 360 by the sum of angles at a point
∴ w° = 360° - ∠DOA = 360° - 176° = 184°
w° = 184°
w° = 2 × v° by angle subtended at the center = 2 × Angle subtended at the circumference
∴ v° = w°/2 = 184°/2 = 92°
v° = 92°
In triangle ΔCDY and ΔABY, we have;
∠ABD = ∠ABY by reflexive property
∠ACD = ∠ACY by reflexive property
∠ACD = ∠ABD = 88°
∴ ∠ABY = 88°
∠CYD = ∠AYB by vertically opposite angles are equal
∴ ∠CYD = 68° = ∠AYB
u° + ∠ABY + ∠AYB = 180° by angle sum property
∴ u° = 180° - (∠ABY + ∠AYB)
u° = 180° - (88° + 68°) = 24°
u° = 24°.

From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles
Complete question :
From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles. Find the experimental probability of randomly selecting a marble that is NOT yellow.
Answer:
Step-by-step explanation:
Total number of marbles :
Blue = 1 ; yellow = 6 ; red = 7 ; green = 4 ; purple = 6
Total = (1 + 6 + 7 + 4 + 6) = 24 marbles
Probability of selecting marble that is not yellow :
Number of marbles that aren't yellow / total number of marbles
Marbles that aren't yellow = 24 - 6 = 18
P(selecting a marble that isn't yellow) = 18 / 24 = 3/4
