Answer:
SP=Rs.700
Step-by-step explanation:
cost price of a copy=R's.25
cost price of 20copy=20×25=Rs.500
profit=Rs.200
selling price of 20 copies=?
Now, we know that,
profit=sp-cp
or, 200=sp-500
or, 200+500=sp
thus, SP=Rs.700
Hence, the selling price of 20copies is 700.

A homeowner is deciding on the size of tiles to use to fully tile a rectangular wall in her bathroom
that is 80 inches by 40 inches. The tiles are squares and come in three side lengths: 8 inches, 4
inches, and 2 inches. State if you agree with each statement about the tiles. Explain your
reasoning
1. Regardless of the size she chooses, she will need the same number of tiles.
2. Regardless of the size she chooses, the area of the wall that is being tiled is the same.
3. She will need two 2-inch tiles to cover the same area as one 4-inch tile.
4. She will need four 4-inch tiles to cover the same area as one 8-inch tile.
5. If she chooses the 8-inch tiles, she will need a quarter as many tiles as she would with 2-inch
tiles.

Step-by-step explanation:
Susie divided a 3-pound bag of apples into 2 equal piles. How many pounds of apples are in each pile?
Answer:
1.5 pounds of apples are in each pie
Step-by-step explanation:
to show our work, lets multiply 1.5 by 2.
(this is the distributive property. the method shown in the image is long multiplication, but they follow the same idea)
for the sake of simplicity, we will write 1.5 as 15.
5×2=10
10×2=20
10+20=30
dont forget the decimal point! since we have one digit in the decimal place, we move the decimal behind one digit in 30.
30.0 --> 3.0 or simply, 3.
this proves that there are 1.5 pounds of apples in each pie. hope this goes more in depth !!! :)

Hi there!
The numbers you have written there are correct.
[tex]-5<x<0[/tex] is true for any value of x that is greater than -5 or less than 0.
When a number is less than 0, we know that it has to be negative.
However, it cannot be more negative than -5. It cannot be -5 either.
So, x could be -1, -2, -3, -4, -1/2, -2.3, -4.9, the list goes on.
I hope this helps!

Answer:
(b) 6^10/7^6
Step-by-step explanation:
The applicable rules of exponents are ...
(a/b)^c = (a^c)/(b^c)
(a^b)^c = a^(bc)
__
This means you have ...
[tex]\left(\dfrac{6^5}{7^3}\right)^2=\dfrac{(6^5)^2}{(7^3)^2}=\dfrac{6^{5\cdot2}}{7^{3\cdot2}}=\boxed{\dfrac{6^{10}}{7^6}}[/tex]
__
Additional comment
I find it helpful to remember that an exponent signifies repeated multiplication. Then ...
[tex]\left(\dfrac{6^5}{7^3}\right)^2=\left(\dfrac{6^5}{7^3}\right)\cdot\left(\dfrac{6^5}{7^3}\right)=\dfrac{6^5\cdot6^5}{7^3\cdot7^3}=\dfrac{6^{5+5}}{7^{3+3}}=\dfrac{6^{10}}{7^6}[/tex]

The mean number of guests on 5 nights is 90. When an extra night of guests is added the mean is 91 . What was the number of guests on the extra night ?
Answer:
96
Step-by-step explanation:
The mean number of 5 nights is 90. It means that the quantity of guests who came these nights is 90*5=450
The mean number of the six nights is 91. So the quantity of guests is 6*91=546
546-450= 96- the quantity of guests that came on the extra night

how do i convert mixed frations into improper fractions\
Answer:
how to convert
Step-by-step explanation:
To convert a mixed number to an improper fraction, follow these steps: Multiply the denominator of the fractional part by the whole number, and add the result to the numerator. Use this result as your numerator, and place it over the denominator you already have. This method works for all mixed numbers
Answer:
Change the whole numbers
Step-by-step explanation:
For example
5 3/6
A whole number written as a fraction for this problem is 6/6.
If the problem was 7 4/9, it would 9/9
I'd the problem was 2 3/4, it would be 4/4.
So basically a whole number written as a fraction is when both the top and bottom number are the same. when divide by each other they equal one. 6 divided by 6 is 1, 9 divided by 9 is 1, 4 divide by 4 is 1.
First
Turn 5 3/6 into 5/1 + 3/6
Now add them to together
To add fractions together they have to have the same denominator or bottom number.
What is a number 1 and 6 have in common ?
6 because 1 can be multiplied with any number but 6 can never be multiplied to create 1.
5 is simple 5 whole numbers
so 5/1 × 6/6= 30/6
30/6 + 3/6 = 33/6
now it's an improper faction. There is no whole number, it been converted into a fraction where the top is bigger than the bottom hence why it is improper
define onto relation.

Two jets leave an airbase at the same time and travel in opposite directions, One jet travels 71mi/h faster than the other. If two jets are 7014 miles apart after 6 hours what is the speed of each jet?
jet1 = 549 mi/h
jet2 = 620 mi/h
x= jet1
x + 71 = jet2
6 hours
6 * x
6 * x + 71
6x + 6x + 426 = 7014
12x = 7014 - 426
12x = 6588
x = 6588/12
x= 549
x + 71 = 620

the volume of the cone is given by the formula V = 1/3 pie r^2 h, where r is the radius of the base and h is the height of the cone. based on this formula, whatis the height, h, of the cone in terms of the volume and height
answer is h=3v/pie r^2. need help with showing work

Answer:
h = 3V/(πr²)
Step-by-step explanation:
The formula can be solved for h by multiplying both sides by the inverse of the coefficient of h.
[tex]V=\dfrac{1}{3}\pi r^2h=\dfrac{\pi r^2}{3}h\\\\(\dfrac{3}{\pi r^2})V=(\dfrac{3}{\pi r^2})(\dfrac{\pi r^2}{3})h\\\\\boxed{\dfrac{3V}{\pi r^2}=h}[/tex]

Additional comment
Whenever a variable has a coefficient you don't want, you can make that be 1 by multiplying the equation by the inverse of the coefficient. This is the same as dividing by the coefficient. This makes use of the fact that for any non-zero 'a', the ratio a/a has a value of 1. Anything multiplied by 1 is unchanged.
V = ah ⇒ V/a = (ah)/a = h(a/a) = h·1 = h
Note that we multiply the whole equation (both sides of the equal sign) by 1/a. The basic rule of equality is that you can do whatever you like to an equation, as long as you do it to both sides.

Given XZ with X(-4,3) and Z(6.-2), find
the coordinates of Y if Y divides XZ one-fifth
of the way from X to Z.
Answer:
Y = (-2,-4)
Step-by-step explanation:
The ratio would be 1:5
so
1/5(6 - -4) + -4 , 1/5(-2 -3) +3
Endpoints of the segment XZ are [tex]X(x_1,y_1)[/tex] and [tex]Z(x_2,y_2)[/tex].
If a point Y(h, k) divides it in the ratio of m : n.
Then the coordinates of the point Y will be,
[tex](\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})[/tex]
If the endpoints are [tex]X(-4,3)[/tex] and [tex]Z(6,-2)[/tex]and point [tex]Y(h.,k)[/tex] divides the this segment in the ratio of [tex]1:5[/tex].
(h, k) = [tex](\frac{1(6)+(5)(-4)}{1+5},\frac{1(-2)+5(3)}{1+5})[/tex]
= [tex](-\frac{14}{6},\frac{13}{6})[/tex]
= [tex](-\frac{7}{3},\frac{13}{6})[/tex]

What is the overall net gain of ATP in cellular respiration per one molecule of glucose?
Between 0-10
between 10-20
between 30-40
between 40-50
The correct answer would be - between 30 to 40 ATPs per molecule of glucose.
In aerobic respiration macromolecules such as glucose break in the presence of oxygen to produce energy. That occurs in mitochondria. The stages of aerobic respiration are glycolysis, the Krebs cycle and ETS.
Glycolysis is the first stage of cellular respiration that is a metabolic pathway of glucose that takes place in the cytosol. Here, the glucose molecule converts into two molecules of pyruvic acid or pyruvate that forms ATP and NADH as energy.
In glycolysis - six ATP molecules are produced. The citric acid cycle is the second stage where In the citric acid cycle, two molecules of ATP are produced. Oxidative phosphorylation of cellular respiration that produces FADH₂ two and eight NADH molecules that produce ATP.Two ATP molecules are produced by one molecule of FADH₂ and therefore the number of ATP produced from 2 FADH₂ is 4 ATP.
NADH produces three ATP molecules by each molecule and therefore the number of ATP produced from 8 NADH is 24 ATP.
The number of ATP produced from the one glucose molecule under aerobic respiration is given as follows:
From glycolysis = 6 ATP
From citric acid cycle = 2 ATP
From FADH₂ = 4 ATP
From NADH = 24 ATP
total 36 ATPs.
Under aerobic respiration 36 molecules of ATP are produced from one molecule of glucose thus, the correct answer would be - between 30 - 40.

write the additive inverse of rational number -11/5
Answer:
Additive inverse of -11/5 => + 11/5
hope that helps uh..☺
Answer:
If " a " represent any rational number then " a + ( - a ) = 0" or " ( - a ) + a = 0 ". Thus " a " and " - a " are additive inverse of each other. Hence " 11 / 5 " is the additive inverse of " - 11 / 5 " .

x/3=y/8=z/5 và 2x+3y-z=50
Step-by-step explanation:
z = 5y/8
x = 3y/8
2x + 3y - z = 50
6y/8 + 3y - 5y/8 = 50
6y/8 + 24y/8 - 5y/8 = 50
25y/8 = 50
25y = 400
y = 16
x = 3y/8 = 3×16/8 = 3×2 = 6
z = 5y/8 = 5×16/8 = 5×2 = 10
