11. Max is designing a hot tub for a local spa.
He wants the hot tub to have a diameter of 89 inches, What is
the approximate area required for the installation of the hot tub?
(Use 3.14 for pi.)
NO PDF PLZ
Answer:
Area required for circular hot tube = 6,218 inch² (Approx.)
Step-by-step explanation:
Given:
Diameter of circular hot tube = 89 inches
Value of π = 3.14
Find:
Area required for circular hot tube
Computation:
Radius of hot tube = Diameter / 2
Radius of hot tube = 89 / 2 inches
Area required for circular hot tube = Area of circle
Area of circle = πr²
Area required for circular hot tube = πr²
Area required for circular hot tube = (3.14)(89/2)²
Area required for circular hot tube = (3.14)(7921 / 4)
Area required for circular hot tube = (3.14)(1,980.25)
Area required for circular hot tube = 6,217.985
Area required for circular hot tube = 6,218 inch² (Approx.)

the volume of the square pyramid is ___ cubic meters
Answer:
6000 m^3
Step-by-step explanation:
The basic formula for the area of a pyramid is 1/3 * b * h
where b is the base and h is the height.
The base is a square, so, we can find the area by squaring the side:
30^2 = 900.
Now, we can plug the values we have into the formula from above:
1/3 * 900 * 20
6000 m^3

Amanda has already run 14 miles on her own, and she expects to run 5 miles during each track practice. How many tracks would it take for Amanda to run 29 miles? heeeeeeeelllllppppp mmmmmeeeee!
Answer:
It will take Amanda 3 track practices to run 29 miles.
Step-by-step explanation:
29-14=15
15/3=5
or
14+5x=29
subtract 14 from both sides
5x=15
divide both sides by 3

What do you used to find perimeter
Answer:
Perimeter = 2 ( l + w )
if u r given for rectangle thats the formula
Step-by-step explanation:
To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).
Determine if the three numbers form a
triangle. If they do, is it an acute, obtuse,
or right triangle?
12, 20, 24
A. acute
B. right
C. obtuse
D. not a triangle
Answer:
In order for three numbers to form a triangle, the sum of any of the two numbers must be greater than the third number. In this case, 12+20>24, 20+24>12, and 12+24>20. Therefore, this is a triangle.
c^2_a^2+b^2
24^2_12^2+20^2
576_144+400
576_544
576>544
This is an obtuse triangle, as c^2>a^2+b^2.

Step-by-step explanation:
You see 2x2 = 4 right and since this is operation 2 / 10 = 5 and 6-5 = 1 so add 1 and that gives you 5
2x2 = 4 / 10/2 = 5 / 6-5 = 1 +4 = 5
Answer:
= 4x + -4
Step-by-step explanation:
Let's simplify:
[tex]2x(2) + 6 -10 \\ = 4x + 6 - 10[/tex]
Combine Like Terms:
[tex]=4x+6+−10

Skyler leased a car for 36 months. Her contract said she can drive 5,000 miles per year
and will have to pay $0.30 per mile above the allowance. If she turns in the car after her
lease term with 25,000 miles driven, how much will Skyler have to pay for the extra
miles (if any)?
Answer:
She has to pay an extra $3,000
Step-by-step explanation:
36 months is 3 years. She is allowed 5,000 miles per year, so 3 x 5,000 = 15,000 miles allowed. But she drove 25,000.
25,000 - 15,000 = 10,000 extra miles
10,000 x 0.30 cents/mile = 3,000
Skyler have to pay for 10000 miles the amount is $3000.
What is the equation?A equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
Skyler leased a car for 36 months.
Her contract said she can drive 5,000 miles per year and will have to pay $0.30 per mile above the allowance.
If she turns in the car after her lease term with 25,000 miles driven.
There are 12 months in a years so in 36 months,
[tex]=\dfrac{36}{12}\\\\=3 \ \rm years[/tex]
There are 3 years in 36 months.
Her contract said she can drive 5,000 miles per year, so in 3 years he drives the car;
[tex]\rm = 5000\times 3\\\\=15000 \ miles[/tex]
If she turns in the car after her lease term with 25,000 miles driven, how much will Skyler have to pay for the extra miles is;
= 25000 - 15000
= 10000
He has to pay extra amount for 10,000 miles which is;
[tex]= 10000\times 0.30\\\\= 3000[/tex]
Hence, Skyler have to pay for 10000 miles the amount is $3000.

Answer:

Step-by-step explanation:
Given
y = 2(x - 3)² + 1
Rearrange making x the subject
Subtract 1 from both sides
y - 1 = 2(x - 3)² ( divide both sides by 2 )
[tex]\sqrt{\frac{y-1}{2} }[/tex] = (x - 3)² ( take the square root of both sides )
± [tex]\sqrt{\frac{y-1}{2} }[/tex] = x - 3 ( add 3 to both sides )

A tepee is designed to have a diameter of 10 feet and the volume of 419 ft.³ at what height the support poles crossed with some of the tepee correctly?
Answer:
The required height is equal to 5.33 feet.
Step-by-step explanation:
Given that,
Diameter, d = 10 feet
Volume, V = 419 ft.³
We need to find the height the support poles crossed with some of the tepee correctly. Let the height is h.
The tepee is in the form of a cylinder. The volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{419}{3.14\times 5^2}\\\\h=5.33\ ft[/tex]
So, the required height is equal to 5.33 feet.

THIS IS HOW YOU CAN FIND ANY MISSING ANGLE - ALSO SOLVES FOR X IN THIS QUESTION.
So, a traingle is 180 degrees.
A line is also 180 degrees.
We know that the angles that make up the triangle are 46, 90, and a missing angle
We need to find the missing angle to find x
To find the missing angle, we must subtract the known angles by the 180 degrees of the traingle.
So:
180-90
=
90
90-46
=
44
So we know the missing angle is 44 degrees.
Let subtract the missing angle(44 degrees) by the 180 degrees of the line:
180-44
=
136
THIS IS WHAT ANSWERS THE OPTION METHOD THAT GIVES THE ANSWER
So x equals 136. This is the missing angle x.
So, remember, both the line and the traingle are 180 degrees.
They both need to find the missing value, which we know is 44
The rest of both the triangle and line is 136 degrees.
Well, 136 degrees on the triangle is the known 90+46 degrees.
Since this will be the same on the line, we can think of x as:
90+46
This looks like answer 1.
Hope this helps! :)

Solve the following system of equations using substitution.
4x + 2y = 12
x = y + 3
Answer:
x = 3
y = 0
Step-by-step explanation:
The method of substitution is when one solves an equation for one of the variables, and then substitutes the expression into the other equation. After doing so, one will solve the other equation for the remaining variable and then backsolve for the first variable.
4x + 2y = 12
x = y + 3
The second equation is already sovled for parameter (x), subttiute this into the other equation,
4(y + 3) + 2y = 12
Distribute,
4y + 12 + 2y = 12
Simplify,
6y + 12 = 12
Inverse operations,
6y + 12 = 12
-12
6y = 0
/6
y = 0
Backsolve for (x), substitute the value of (y) into the equation for (x) and solve,
x = y + 3
x = 0 + 3
x = 3
Answer: look at the picture, sorry I can’t solve x = y + 3 for x.

One angle of a triangle measures 24 more than the smallest angle in the triangle. The third angle measures twice the measure of the smallest angle.
What is the measure of the smallest angle?
24
39
52
54
Answer:
smallest angle measure 39 degrees
Step-by-step explanation:
the sum of the three interior angles in a triangle is always 180°
x= smallest
x +x+24 + 2x = 180
4x +24 = 180
4x = 156
x = 39
Answer:
B. 39°
Step-by-step explanation:
x + 24 + 2x + x = 180 is the equation I'll use.
x + 24 + 2x + x = 180 {Step 1: Combine 2x, x, x to get 4x.}
4x + 24 = 180 {Step 2: Subtract 24 from both sides (180 - 24 = 156)}
4x = 180 - 24
4x = 156 {Step 3: Divide both sides by 4 (156 / 4 = 39)}
x = 156/4
x = 39
The smallest angle is 39°. (The other two angles are 63° and 78°, respectively.)
