Step-by-step explanation:
Let's change 2 2/3 cups to 4/3 cups and change 6 3/4 cups to 18/4 cups. Okay now we need to find a number 4 and 3 both go into bucause they're the numbers on the bottom or the denominator 4 and 3 both go into 12 so now we put our numerator (the numbers on top) over 12.
The sum is now: 54/12 + 16/12 let's change that to 4 and 4/12 + 1 and 4/12= 5 and 8/12 simplify that to 5 and 2/3
12 identical coins are placed in the cells on a chess board with 4 rows and 4 columns. If coins are not
allowed to be placed in the same cell, how many ways are there so that there are 3 coins in every rows
and columns?
Answer:
24 waysStep-by-step explanation:
If the coins are identical and not numbered, we need to find the number of patterns.
There are 4 rows and 4 columns. One cell remains empty in each row.
There are 4 options for the first row, 3 options for the second row, 2 options for the third row and 1 option for the fourth row.
The number of options reduces to avoid more than 1 empty cell in each row or column.
Number of options is:
4*3*2*1 = 24_________
[tex] \: [/tex]
4rows, and 4columns.
Soo :
= 4!
= 4 × (4 - 1) × (4 - 2) × (4 - 3)
= 4 × 3 × 2 × 1
= 24
How do I find the Derivative of a Function where the x is a number?
If I was to find d/dx g(1) for example, would I first find the value of the function g(x) at x=1 and then find the derivative of that which becomes 0 because the result would probably be a constant. Or do I first find the derivative of g(x) and then plug in x=1 to calculate it?
Thanks
Given a function g(x), its derivative, if it exists, is equal to the limit
[tex]g'(x) = \displaystyle\lim_{h\to0}\frac{g(x+h)-g(x)}h[/tex]
The limit is some expression that is itself a function of x. Then the derivative of g(x) at x = 1 is obtained by just plugging x = 1. In other words, find g'(x) - and this can be done with or without taking a limit - then evaluate g' (1).
Alternatively, you can directly find the derivative at a point by computing the limit
[tex]g'(1) = \displaystyle\lim_{h\to0}\frac{g(1+h)-g(1)}h[/tex]
But this is essentially the same as the first method, we're just replacing x with 1.
Yet another way is to compute the limit
[tex]g'(1) = \displaystyle\lim_{x\to1}\frac{g(x)-g(1)}{x-1}[/tex]
but this is really the same limit with h = x - 1.
You do not compute g (1) first, because as you say, that's just a constant, so its derivative is zero. But you're not concerned with the derivative of some number, you care about the derivative of a function that depends on a variable.

Outliers can cause the _________ to be misleading when summarizing a data set.
A. mean
B. interquartile range
C. all of these
D. median
Answer:
A. Mean
Step-by-step explanation:
Mean, because it's the average of the numbers and if one number's way off, it would throw the average off by a lot! I honestly forgot a bit about interquartile ranges, but it doesn't affect the median at all/have a very little effect so that's why it's not all of these. But mean is for sure!

What is the value of x to the nearest tenth? 6.0? 13.4? 30.0? 26.8?
Answer:
26.8
Step-by-step explanation:
2×√(18²-12²)
= 26.8328157..
= 26.8 (rounded to the nearest tenth)
Answer:
26.8
Step-by-step explanation:
We can use the Pythagorean theorem
a^2+b^2 = c^2
where a and b are the legs and c is the hypotenuse
12^2+ b^2 = 18^2
144+b^2 = 324
b^2 = 324-144
b^2 = 180
Taking the square root of each side
sqrt(b^2) = sqrt(180)
b = 13.41640
We know b = 1/2x
2b =x
2(13.41640) =x
26.83281573 =x
26.8

the area of square is 64cm square .find its length
Answer:
8 cm
Step-by-step explanation:
Because A=a*a
Area equals length times length
So, 8 is the length
64 divided by some number must equal the exact same number. Let me show what I am talking about.
Our length is a. We multiply a times itself (because that's the formula for the square's area)
Does this number exist?
Yes, it does.
And it's a whole number.
And we know from our times tables that 8*8=64

HELPPP PLZZZZ DUE SOON
Answer:
3rd option
Step-by-step explanation:
Given T is the midpoint of SU , then
ST = TU , that is
9x = 4x + 25 ( subtract 4x from both sides )
5x = 25 ( divide both sides by 5 )
x = 5
Then
ST = 9x = 9 × 5 = 45

Find 'x' in the following
First we have to find angle D
As it is a quadrilateral
[tex]\\ \sf\longmapsto <A+<B+<C+<D=360[/tex]
[tex]\\ \sf\longmapsto 45+50+35+<D=360[/tex]
[tex]\\ \sf\longmapsto 130+<D=360[/tex]
[tex]\\ \sf\longmapsto <D=360-130[/tex]
[tex]\\ \sf\longmapsto <D=230°[/tex]
Now
[tex]\\ \sf\longmapsto <D+x=360[/tex]
[tex]\\ \sf\longmapsto x+230=360[/tex]
[tex]\\ \sf\longmapsto x=360-230[/tex]
[tex]\\ \sf\longmapsto x=130°[/tex]
Answer:
x = 130
Step-by-step explanation:
Sum of all the angle of quadrilateral = 360°
50 + 45 + 35 + ∠ADC = 360
130 + ∠ADC = 360
∠ADC = 360 - 130
∠ADC = 230
x = Reflex ∠ADC
= 360 - 230
= 130
3. In a school, there are 450 students in total. If 2⁄3 of the total students are boys, find the number of girls in the school. What percent of the students are boys? Show your work or explain how you calculated your answer
Answer:
150 girls
66.7%
Step-by-step explanation:
2/3 × 450 = 300 boys
450 - 300 =150 girls
second question:
300/450 × 100
=66.66666667
=66.7% Students are boys
There are 150 girls in the school, and approximately 66.67% of the students are boys.
What percent of the students are boyslet's break this down step by step:
1. Total number of students: 450
2. Boys make up 2/3 of the total students.
Number of boys = (2/3) * 450
= 300 boys
3. To find the number of girls, subtract the number of boys from the total:
Number of girls = Total students - Number of boys
= 450 - 300
= 150 girls
Now, let's calculate the percentage of students that are boys:
Percentage of boys = (Number of boys / Total students) * 100
= (300 / 450) * 100
= 66.67%
So, there are 150 girls in the school, and approximately 66.67% of the students are boys.
