If one kilogram equals 2.2 pounds, how many kilograms equal 112 pounds? Round your answer to the nearest hundredth, if necessary. 24.64 kilograms 50.91 kilograms 109.8 kilograms 246.4 kilograms
Answer:
B.) 50.91 kilograms
Step-by-step explanation:
Write an equation that looks like this:
[tex]\frac{kilogram}{pound}= \frac{kilogram}{pound}[/tex]
Insert the information in the appropriate section, with 1 kilogram and 2.2 pounds on the same side:
[tex]\frac{1}{2.2}=\frac{x}{112}[/tex]
Solve for x, which is the number of kilograms for 112 pounds if there is 1 kilogram per 2.2 pounds.
Solve for x. Cross multiply:
[tex]1(112)=2.2(x)\\\\112=2.2x[/tex]
Isolate the variable. Divide both sides by 2.2:
[tex]\frac{112}{2.2}=\frac{2.2x}{2.2}\\\\x= 50.909090...[/tex]
Round to the nearest hundredth (two decimal places to the right):
50.909 → 50.91
If 1 kilogram is equal to 2.2 pounds, then 50.91 kilograms is equal to 112 pounds.

i need help finding out the pattern of 3 and 4
Answer:
See below.
Step-by-step explanation:
For 3, we have:
1, 3, 6, ___, 15, 21, _____, 36, _______
Let's try to determine the pattern. From 1 to 3, we added 2.
From 3 to 6, we added 3.
So, it seems that the fourth term would be to add 4, and then add 5. Let's try it:
6+4=10
10+5=15.
So, it seems we're correct. So, we will add 6, then 7, and then 8, etc. Therefore, our correct sequence would be:
1 (+2), 3 (+3), 6 (+4), 10 (+5), 15 (+6), 21 (+7), 28 (+8), 36 (+9), 45
For 4, we have:
100, _____, 64, ______, 36, 25, _______
Notice that these all are perfect squares. 10 squared is 100, 8 squared is 64, etc. Thus, we can rewrite this as:
10², _____, 8², ______, 6², 5², ______
Therefore, our blanks would be:
10², 9², 8², 7², 6², 5², 4².
Evaluated, this woul be:
100, 81, 64, 49, 36, 25, 16.
And we're done!

You have 20 gallons of roof coating to apply to the roof of a mobile home that is 16 feet wide. Twenty gallons covers 760 to 1000 square feet. Find the interval for the length of x that you will cover before you need to buy more roof coating.
Area = length x width.
Divide the two total areas by the width to find the lengths:
760/16 = 47.5
1000/16 = 62.5
The interval is:
47.5<= x <= 6.5
The interval for the length of x that you will cover before you need to buy more roof coating will be 47.5 ≤ x ≤ 6.5.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.The space occupied by any two-dimensional figure in a plane is called the area.

A jar contains 6 yellow marbles, 4 black marbles, and 2 purple marbles. Two marbles are picked at random, without replacement. What is the probability of
selecting both yellow?
Answer:
The probability of selecting both yellow is 5/22.
Step-by-step explanation:
Given the number of yellow marbles = 6
Black marbles = 4
Purple marble = 2
Now find the total number of marbles in the jar.
Thus total marbles = Yellow marbles + Black marbles + Purples marble
Now insert the values in the above formula.
Total marbles = 6 + 4 + 2
Total marbles = 12
The probability of 2 yellow marble:
[tex]= \frac{6}{12} \times \frac{5}{11} \\= \frac{5}{22}[/tex]
Thus, the probability of selecting both yellow is 5/22.

Answer:
9
Step-by-step explanation:
we have
[tex]|\frac{27}{-3}|\\\\=|-9|[/tex]
and absolute value of -9 is 9
so answer is 9
f(x) = 9 - x, g(x) = x2 + x, h(x) = x - 2
Compute the following:
f(g(4)
Answer:
f(g(4) = -11
Step-by-step explanation:
Whenever we are given a composite function where the output of one of the functions serves as an input for the second one, the first step is to evaluate the numerical output from the first function.
Output from first function: g(x) = [tex]x^{2} + x[/tex]
g(4) will be evaluated by substitution 4 for x in the above equation.
this will give us [tex]g(x)=4^{2}+4 =20[/tex]
Output from the composite function f(g(4)
The next stage is to input our results from the function g(4) into the function
f(x) = 9 - x. The output from g(4) which is 20, will now become our input.
[tex]f(x)-9-(20)= -11[/tex]
Therefore f(g(4) = -11
-3(4x+2)=18 WHAT IS IT????
Answer:
x = -2
Step-by-step explanation:
-3(4x + 2) = 18
Divide by -3:
-3(4x + 2) / -3 = 18 / -3
4x + 2 = -6
Subtract 2:
4x + 2 - 2 = -6 - 2
4x = -8
Divide by 4:
4x / 4 = -8 / 4
x = -2

Can 6,12, and 18 make a triangle?
By definition, 3 side lengths are a triangle if any 2 side lengths add up to be greater than the third.
We can already see that the side lengths 6 and 12 will add up to a value of 18, which is equal to the last side length, meaning that the three values are not a triangle.
[tex]a=6[/tex]
[tex]b=12[/tex]
[tex]c=18[/tex]
[tex]a+b>c[/tex]
[tex]b+c>a[/tex]
[tex]c+a>b[/tex]
[tex]6+12>18[/tex] (Since this is not true, this is not a triangle)
