As seen in the diagram below, Shandra is building a walkway with a width of xx feet to go around a swimming pool that measures 8 feet by 6 feet. If the total area of the pool and the walkway will be 168 square feet, how wide should the walkway be?
The total surface area of the building is the sum of the total faces an object contains. The walkway should be about 2.57feet
How to calculate the total surface area the building?The total surface area of the building is the sum of the total faces an object contains. The formula is expressed as:
TSA = 2(lw + wh + lh)
where
l is the lengthw is the widthh is the heightGiven the following parameters
TSA = 168 square feet
length = 8feet
Height = 6 feet
Required
Width of the walkway
Substitute
168 = 2(lw + wh + lh)
84 = (8(6) + 6w + 8w)
84 = 48 + 14w
14w = 84 - 48
14w = 36
w = 2.57feet
Hence the walkway should be about 2.57feet

A graph is a way to represent a lot of data in a visual format. The graph can be drawn as using the equation y=100x+24.
What is a graph?A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.
Given a factory-made 424 items in 4 hours at a constant rate. Also, the table is given, therefore, the slope of the line can be written as,
m = (400-300)/(4-3) = 100
Therefore, the equation can be written as y=100x+C
now, substituting the point we will get,
424 = 100(4) + C
424 - 400 = C
C = 24
Therefore, the graph can be drawn as using the equation y=100x+24.

Stuck on this. 60 points!
Answer:
Statement 1 and 2
Step-by-step explanation:
If you take t^2 - 16t + 55 and find some of its graphical values, you will get:
Turning point: (8,-9)
Roots: (5,0) and (11,0)
When this graph is plotted and you imagine the x axis to be time (as stated in the question), each of the roots (x - intercept) must be when the swimmer goes under and when they come back up.
This means that the swimmer dived under the water at 5 seconds and came back up at 9, making the first 2 statements correct.
Now the fourth statement is ruled out.
The fifth statement is not plausible as the graph would have to have more than 2 roots for the swimmer to enter the water twice.
That leaves the third statement. If you imagine the depth of the swimmer to be the y axis of our imaginary graph, and we know that the y axis of the turning point is -9, that means that the swimmer's deepest dive was 9 feet under the water, ruling out the third statement too.
Hope this helps :D
Answer:
[tex]h(t)= (t-5)(t-11)[/tex]
The swimmer comes back up 11 seconds after the timer is started.
The swimmer dives into the water 5 seconds after the timer is started.
Step-by-step explanation:
Given function:
[tex]h(t)=t^2-16t+55[/tex]
To factor a quadratic in the form [tex]ax^2+bx+c[/tex],
find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]:
[tex]\implies ac=55[/tex]
[tex]\implies b=-16[/tex]
Two numbers that multiply to 55 and sum to -16 are: -11 and -5
Rewrite b as the sum of these two numbers:
[tex]\implies t^2-11t-5t+55[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies t(t-11)-5(t-11)[/tex]
Factor out the common term (t - 11):
[tex]\implies (t-5)(t-11)[/tex]
Therefore, the given formula in factored form is:
[tex]h(t)= (t-5)(t-11)[/tex]
The swimmer's depth is modeled as h(t). Therefore, when h(t) = 0 the swimmer will be at the surface of the water.
[tex]\implies h(t)=0[/tex]
[tex]\implies (t-5)(t-11)=0[/tex]
[tex]\implies t-5=0\implies t=5[/tex]
[tex]\implies t-11=0 \implies t=11[/tex]
Therefore, the swimmer will be at the surface of the water at 5 s and 11 s.
The swimmer's maximum depth is the vertex of the function. The x-value of the vertex is the midpoint of the zeros. Therefore, the x-value of the vertex is t = 8.
Substitute t = 8 into the function to find the maximum depth:
[tex]\implies h(8)=8^2-16(8)+55=-9[/tex]
So the swimmer's maximum depth is 9 ft.

The swimmer comes back up 11 seconds after the timer is started.

Answer:
8x+19=9x+9
Step-by-step explanation:
Simplifying
(8x + 19) = (9x + 9)
Reorder the terms:
(19 + 8x) = (9x + 9)
Remove parenthesis around (19 + 8x)
19 + 8x = (9x + 9)
Reorder the terms:
19 + 8x = (9 + 9x)
Remove parenthesis around (9 + 9x)
19 + 8x = 9 + 9x
Solving
19 + 8x = 9 + 9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x' to each side of the equation.
19 + 8x + -9x = 9 + 9x + -9x
Combine like terms: 8x + -9x = -1x
19 + -1x = 9 + 9x + -9x
Combine like terms: 9x + -9x = 0
19 + -1x = 9 + 0
19 + -1x = 9
Add '-19' to each side of the equation.
19 + -19 + -1x = 9 + -19
Combine like terms: 19 + -19 = 0
0 + -1x = 9 + -19
-1x = 9 + -19
Combine like terms: 9 + -19 = -10
-1x = -10
Divide each side by '-1'.
x = 10
Simplifying
x = 10
Answer:

Step-by-step explanation:
using the tangent ratio in the right triangle
tan63° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{IJ}{JK}[/tex] = [tex]\frac{1}{x}[/tex] ( multiply both sides by x )
x × tan63° = 1 ( divide both sides by tan63° )
x = [tex]\frac{1}{tan63}[/tex] ≈ 0.5 ( to the nearest tenth )
Answer:
x = 0.5
Step-by-step explanation:
We can use tan Θ to find the value of x.
tan Θ = Opposite ÷ Adjacent

tan 63 = 1 ÷ x
1.9626 = 1 ÷ x
x = 1 ÷ 1.9626
x = 0.5095

Yes, she did not use the correct area formula for a rectangle. Yes, she calculated the cost incorrectly. No, she didn’t make any errors.
Answer:
Yes, she should have only added the area of five of the six faces.
Step-by-step explanation:
The formula for determining the surface area of a cuboid or box is expressed as
Surface area = 2lw + 2lh + 2wh
Where l, w and h represents length, width and height of the box respectively.
2lw represents the area of the top and the bottom of the box. Since she doesn't want to cover the bottom, it becomes lw. Therefore,
Surface area = 15 + 6 + 6 + 10 + 10 = 47 in².
The cost would be
0.25 × 47 = $11.75
Therefore,
Yes, she should have only added the area of five of the six faces.

13 = m/4 + 7 can you show work too
The correct value of this equation is m = 24
Resolution methodThis equation contains a fractional term. We note that the denominator of this equation is the term 4. Therefore, we will multiply the sides by 4:
13 = m/4 + 7
13 . 4 = 4(m/4) + 7 . 4
52 = m + 28
Now, let's isolate the variable "as negative" and after the equality - we'll be subtracting the terms:
52 = m + 28
-m = 28 - 58
-m = -24
m = 24
Therefore, the correct value of this equation will be m = 24
Find CE.

The length of the chord CE is 24.46 in
To find the length of the chord CE, we solve the question using pythagoras' theorem
What is a chord?A chord is a line segment touching two points in a circle.
What is pythagoras' theorem?Pythagoras' theorem states that in any right angled triangle with sides a, b and c where c is the hypotenuse side, we have that
c² = a² + b²
The required triangle
Now form the diagram the radius of the circle BE forms a right angled triangle with the perpendicular to the chord, BO and the midway between the chord, OE.
BO = BD - OD
= 20 in - 5 in
= 15 in
From pythagoras,
BE² = DE² + BO²
making DE subject of the formula, we have
DE = √(BE² - BO²)
DE = √((20 in)² - (15 in)²)
DE = √(400 in² - 225 in²)
DE = √(175 in²)
DE = 13.23 cm
The length of the chord
Since the chord CE = 2DE,
So, CE = 2 × 13.23 in
= 26.46 in
So, the length of the chord CE is 24.46 in
