Answer:
A. x = 212
Step-by-step explanation:
This scale is showing us that x + 122 is equal to 334 because the scale is balanced and we can see an equal sign (=) in the center. We will set up an equation and solve for x.
[Equation]
x + 122 = 334
[Subtract 122 from both sides]
x = 212
A. x = 212

Answer:
120
Step-by-step explanation:
5 factorial
There are total 120 ways to arrange the letters of word "COUNT".
What is permutation?A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
Permutation Formula[tex]nP_{r} =\frac{n!}{(n-r)!}[/tex]
Where,
P is the number of arrangements.
r is the of objects selected.
n is the total numbers of object.
According to the question.
We have a word "COUNT".
Total number of letters in word "COUNT" is 5.
⇒ Total number of objects, n = 5
Since, we have to form different words by using 5 letters of count.
⇒ Total number of objects we have to select, r = 5
Therefore, the total number of ways to arrange the letters of "COUNT" is given by
[tex]5P_{5}=\frac{5!}{(5-5)!}[/tex]
⇒[tex]5P_{5} =\frac{5!}{0!}[/tex]
⇒[tex]5P_{5} =\frac{5!}{1}[/tex] (because,0! = 1)
⇒[tex]5P_{5} = 5(4)(3)(2) = 120 ways[/tex]
Hence, there are total 120 ways to arrange the letters of word "COUNT".

A cooler has a 60-L capacity. Its internal length is 60 cm and its internal width is 35 cm. Determine the internal height and the internal surface area of the cooler.
Hint 1 cm^3=1 ml
Answer:
28.5714285714286 cm
Step-by-step explanation:
1 L = 1000 mL
1 L = 1000 cm^3
60 L = 60,000 cm^3 (multiply both sides by 60)
The cooler has volume of 60,000 cubic cm. Let V = 60000
Assuming the cooler is a rectangular prism (aka a block), then we can say
volume = length*width*height
V = L*W*H
60000 = 60*35*H
60000 = 2100H
2100H = 60000
H = 60000/2100
H = 28.5714285714286 which is approximate
And the surface area (SA) is
SA = 2*(LW + LH + WH)
SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)
SA = 9628.57142857143 which is also approximate
Units for the surface area are in square centimeters.

A statement that best compares the average values of the number of fish caught at both lakes daily:
There is a significant difference between the sample means.
What is average?The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the sum of the total number of observations by the total number of observations.
The mean number of catfish caught daily at Lake Martin is 85,
with the number of catfish ranging from 75 to 140.
The mean number of catfish caught daily at Smith Lake is 104,
with the number of catfish ranging from 96 to 183.
The difference in all the sample means,
104 - 85 = 19.
Therefore, the difference is 19.

Find: KF
m∠DFE
Answer:
So let me help you!

KF = 8 units
m∠DFE = 90°
-
We know that DK is 16 so you would just have to divide it by 2

-
Since EF is a bisector, split it right down the middle means it will be equal to 90 degrees.

Prove that any number n of the form abcabc, where a, b, and c are decimal digits, is divisible by 7, 11 and 13.
We can factorize abcabc as
abcabc = abc000 + abc
abcabc = abc (1000 + 1)
abcabc = abc × 1001
abcabc = abc × 7 × 11 × 13
so naturally each of 7, 11, and 13 must divide abcabc.

What is the surface area of the square pyramid represented by the net? 5ft 3ft 3ft 5ft 5ft 5ft
Answer:
39 ft²
Step-by-step explanation:
I assume the base is a square 3 ft by 3 ft, and the height of each triangular side is 5 ft.
SA = s² + 4 × bh/2
SA = (3 ft)² + 4 × (3 ft)(5 ft)/2
SA = 9 ft² + 30 ft²
SA = 39 ft²

Answer:
y=mx+b
Points are in (x,y) form so 5 is x and -6 is y
We know m = -1/7 (because m is slope)
So we can plug these values in to find b.
