The shed in Stephanie’s back yard has a door that measures 6 feet high and 3 feet wide. Stephanie would like to buy and store a ladder in the shed diagonally. What is the maximum height, in feet, of a ladder she can buy to fit through the door?
Answer:
the answer is 6 ft hope it helps
The maximum height, in feet, of a ladder she can buy to fit through the door is, 6.7 feet
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
We have to given that;
The shed in Stephanie’s back yard has a door that measures 6 feet high and 3 feet wide.
Now, By using Pythagoras theorem;
The length of a ladder she can buy to fit through the door is, x
⇒ x² = 6² + 3²
⇒ x² = 36 + 9
⇒ x² = 45
⇒ x = √ 45
⇒ x = 6.7 feet
Thus, The maximum height, in feet, of a ladder she can buy to fit through the door is, 6.7 feet

I used half the sugar to make cookies then I used another 2 cups for a really big cake I had 4 cups of sugar left how many cups of sugar did I start with
Answer:
12 cups of sugar
Step-by-step explanation:
Total cups of sugar = x
Cookies = 1/2x
Big cake = 2 cups
Sugar left = 4 cups
x = 1/2x + 2 + 4
Collect like terms
x - 1/2x = 6
1/2x = 6
Divide both sides by 1/2
x = 6 ÷ 1/2
= 6 × 2/1
= 12/1
x = 12 cups of sugar

11) 6x2+ 6x3
12) -6x 2 + (-6) x3
13) 5x - 8x
Answer:
11) 6x^2+ 6x^3 = 6.x.x+6.x.x.x
12) -6x^2 + (-6) x^3 = -6.x.x + (-6).x.x.x
13) 5x - 8x = 5.x -8.x
Step-by-step explanation:
Let us solve the question one by one.
11) 6x^2+ 6x^3
In order to convert the polynomial in the factored form, we see which factors are common in all terms in the polynomial.
[tex]6x^2 = 6.x.x\\6x^3 =6.x.x.x[/tex]
The factored form is:
[tex]= 6.x.x+6.x.x.x[/tex]
12) -6x^2 + (-6) x^3
Similarly, as 11
[tex]-6x 2 =-6.x.x\\-6x^3=-6.x.x.x[/tex]
The factored form is:
[tex]=-6.x.x+ (-6).x.x.x[/tex]
13) 5x - 8x
We can clearly see that there is only one common factor in both terms which is x
[tex]5x = 5.x\\8x = 8.x[/tex]
The factored form is:
[tex]=5.x-8.x[/tex]
Hence,
11) 6x^2+ 6x^3 = 6.x.x+6.x.x.x
12) -6x^2 + (-6) x^3 = -6.x.x + (-6).x.x.x
13) 5x - 8x = 5.x -8.x
write a expression that represents the height of a tree that begins at 8 feet and increases by 2 feet per year. Let t represent the number of years. How tall will the tree be in 5 years?
Answer:
8 + 2t
In five years, 18 feet
Answer:
8 + 2(t)
Step-by-step explanation:
8 is the initial height of the tree, and 2 represents the growth per year, and each year is calculating by represnting each year as (t), so
ex.
2 years pass
8 + 2(2) = 8 + 4 = 12ft
2ft per year, 2 years = 4

Write the repeating decimal $0.\overline{51}$ as a fully simplified fraction.
Answer:
17/33
Step-by-step explanation:
The repeating decimal [tex]$0.\overline{51}$[/tex] is equal to [tex]$\boxed{\frac{17}{33}}$[/tex].
What is a fraction?A fraction is a component of a whole. Mathematically, the number is expressed as a quotient, where the numerator and denominator are divided. In a simple fraction, both are integers. In a complex fraction, a fraction can be found in either the numerator or the denominator. A suitable fraction has a numerator that is smaller than its denominator.
Let [tex]$x = 0.\overline{51}$[/tex]. Multiplying both sides of this equation by 100 gives,
[tex]$100x = 51.\overline{51}\\[/tex]. Subtracting the first equation from the second equation eliminates the repeating decimal,
giving:
[tex]\begin1100x - x &= 51.\overline{51} - 0.\overline{51}\\ \99x &= 51 \\\ \\end[/tex]
x = 51/99
Therefore, the repeating decimal [tex]$0.\overline{51}$[/tex] is equal to [tex]$\boxed{\frac{17}{33}}$[/tex].

Divide -2 on both sides: x < 6Here we see that any value x smaller than 6 would work as a solution to the inequality.
Answer:

Step-by-step explanation:
Hello!
We can solve inequalities the same way as we solve equations. The most important rule is that when you divide or multiply both sides by a negative number, flip the sign.
Solve for x-2x > -12-2x / -2 < -12 / -2 (flip the sign!)x < 6The solution set for x is all values less than 6.

So the value of n is 4A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,260 ft Determine the flag's width and length if the length is 290 ft greater than the width.
Answer:
length= 710 width= 420
Step-by-step explanation:
As we consider a rectangle we can replace "length" with l and "width" with w so that the perimeter will be:
2l+2w= 2260
With the length as:
l= w+290
The length, substituted into the perimeter is:
2(w+290)+2w=2260
Distribute:
4w+580=2260
Subtract:
4w=1680
Divide:
w=420
To find the length, take the width and add 290:
420+290=710
l=710
14 People fit comfortably in a 5 feet by 5 feet area. Use this value to estimate the size of a crowd that is 5 feet deep on both sides of the street along a 2-mile section of a parade route.
Answer:
29568
Step-by-step explanation:
Given that:
Length of road = 2 miles
Number of people who can fit in a area of 5 feet by 5 feet = 14
To find:
Number of people that can fit in the road of the given dimensions.
Solution:
Given that one side 2 miles wide and 5 feet deep.
First of all, we need to find number of 5 feet by 5 feet block that can be made in the given dimensions.
2 miles = 10560 feet
Number of blocks = [tex]\frac{10560}{5}[/tex] = 2112
Number of persons that can fit in one block = 14
Number of persons that can fit in 2112 blocks = 14 [tex]\times[/tex] 2112 = 29568
Therefore, the answer is: 29568

MATH HELP PLEASE !!!! Tickets to a local movie were sold at $5.00 for adults and $3.00 for students. If 150 tickets were sold for a total of $610.00, how many adult tickets and student tickets were sold.
Answer:
A = 80 S =70
Step-by-step explanation:
#Adults tickets = A
#Students tickets = S
A + S = 150
5A (means the price is $5 times the number of Adult tickets) equals the total amount for all of the Adult tickets altogether
3S (means the price is $3 times the number of Student tickets) equals the total amount for all of the students tickets altogether
5A + 3S = 610 (Means adding the total of all the student tickets plus adult tickets will equal $610 for all tickets sold)
Using both equations now, you can use substitution or elimination to solve for one of the variables. Then you can use the variable to substitute to solve the remaining one.
A + S = 150
5A + 3S = 610
Substitution:
A = 150 - S (Rearrange the first equation by moving S to the other side)
Substitute into the other equation
5 (150 - S) + 3S = 610
750 - 5S + 3S = 610 Combine like terms : -2S = -140
Solve for S = 70
Substitute into A + S = 150 A + (70) = 150
A = 80
