Answer:
1. c=13
2. a=12
Step-by-step explanation:
We have to use the Pythagorean theorm
a^2+b^2=c^2
(5*5)+(12*12)=c^2
25+144=c^2
169=c^2
Now we have to square root 169 to find c
[tex]\sqrt{169}[/tex]
c=13
For this one we have to do c^2-b^2=A^2
(15*15)-(9*9)
225-81=a^2
144=a^2
[tex]\sqrt{144}[/tex]
a=12

Which of the following is a polynomial?
Answers
Answer:
C
Step-by-step explanation:
Polynomials should consist of only non-negative integer powers of x. Thus B and D are definitely not. It might be possible to simplify A into something that looks like a polynomial, but it’s a bit difficult. If you just need to choose one, then C is definitely a good choice.
My incomplete attempt of factorizing A:

Answer:
h ≈ 448.0 m
Step-by-step explanation:
The relevant trig function is the one that relates adjacent side length, opposite side length, and angle:
Tan = Opposite/Adjacent
Solving for the adjacent side length, we get ...
Adjacent = Opposite/Tan
For the two angles given, we want the value of the difference of the adjacent side lengths:
168 m = h/tan(41.2°) -h/tan(52.5°)
Then h is found by dividing by its coefficient:
h = (168 m)/(1/tan(41.2°) -1/tan(52.5°))
h ≈ 448.0 m

A number is 4 times another number. Their sum is 30.
Answers
Answer:
24 and 6 are the 2 numbers
Step-by-step explanation:
let the 2 numbers be x and y , then
x + y = 30 → (1)
y = 4x → (2) [ one number is 4 times the other ]
Substitute y = 4x into (1)
x + 4x = 30
5x = 30 ( divide both sides by 5 )
x = 6
Substitute x = 6 into (2)
y = 4 × 6 = 24
The 2 numbers are 24 and 6

You have a box of 11 art projects that weighs 24 pounds. If you give your mom 7 of
your art projects, how much would her box weigh?
Answers
Answer:
15.2726
Step-by-step explanation:
so you figure out how much individual box weighs by dividing 24 by 11, which equals 2.1818. Then you times what you figured out what a single art project weighs (2.1818) by seven, and that gets you 15.2726
Answer:
15.27 ≅ 15 pounds if I'm not wrong :(
Step-by-step explanation:
11 projects : 24 pounds
7 projects : x pounds
x = (24 × 7) ÷ 11 = 15.27

Expalin or show your reasoing
Answers
Answer:
The answer is below
Step-by-step explanation:
The volume of a box with a length of l, width of w and a height of h is given by the formula:
volume of the box = length * width * height = lwh
The volume of a cylinder with a height of h, and radius r is given by the formula:
volume of the cylinder = π * radius² * height = πr²h
Since the box and the cylinder have the same height and the cylinder is wide enough for the box to be placed inside, this means that the box has a volume greater than that of the cylinder. Hence:
If the box can take 8 cups, the cylinder would be able to take 10 cups.

Answer:
x = 15
Step-by-step explanation:
Simplifying
3x + (8x + 15) = 180
Reorder the terms:
3x + (15 + 8x) = 180
Remove parenthesis around (15 + 8x)
3x + 15 + 8x = 180
Reorder the terms:
15 + 3x + 8x = 180
Combine like terms: 3x + 8x = 11x
15 + 11x = 180
Solving
15 + 11x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 11x = 180 + -15
Combine like terms: 15 + -15 = 0
0 + 11x = 180 + -15
11x = 180 + -15
Combine like terms: 180 + -15 = 165
11x = 165
Divide each side by '11'.
x = 15
Simplifying
x = 15
Answer:
x=15 Hope this helps :)

A 2-column table with 9 rows. The first column is labeled year with entries 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010. The second column is labeled pounds of trash with entries 3.25, 3.25, 3.66, 3.83, 4.57, 4.52, 4.74, 4.69, 4.44.
The table shows the average number of pounds of trash generated per person per day in the United States from 1970 to 2010. Use the statistics calculator to calculate the mean and median. Round the answers to the nearest hundredth.
Answers
Answer:
The median of a list of numbers is the center number when you order the numbers from least to greatest.
Since there are 9 numbers; the center number is the fifth number. Four numbers below and four numbers above. Median is 4.44 and the mean or average is 4.09.
Step-by-step explanation:
List in order from least to greatest
(3.25, 3.25, 3.66, 3.83) 4.44 ( 4.52, 4.57, 4.69, 4.74) Notice 4 numbers below 4.44 are lower and 4 numbers above 4.44 are higher. So the median number is 4.44
For the mean you add all the number and divide the sum by the number of numbers you have. We know you have 9 numbers from the first part. So, add the numbers from the list (3.25 +3.25+ 3.66 + 3.83 + 4.44 + 4.52 + 4.47 + 4.69 + 4.74) = 36.85 Then divide by 9 = 4.09
