The quotient of 1/3 and 4/3
Answer:
1/ 4
Step-by-step explanation:
The question can also be written as [tex]\frac{1}{3} /\frac{4}{3}[/tex] .
Because it's division of fractions, you can multiply to find the answer by making 4/3 into 3/4. So
1/ 3 times 3/4 = 3/12 = 1/4
Answer:
if you're trying to find the quotient then the answer is: 4/9
if you're trying to add then the answer is: 5/3
if you're trying to divide then the answer is: 4/9
if you're trying to multiply then the answer is: 4/9
if you're trying to simplify then the answer is: 4/9

The area of the surface of the largest known star is about 1015 square miles. The area of the surface of the Earth is about 1011 square miles. How many times larger is the star's area?
Answer:
The surface area of the star is approximately 1.004 times larger than the earth's surface area
Step-by-step explanation:
To find the number of times b which the area of the star is larger than that of the earth, we will divide the area of the area of the star by the area of the earth.
Area of surface of star = 1015 square miles
Area of surface of the earth = 1011 square miles
∴ (Area of star) ÷ (Area of the earth)
= 1015 ÷ 1011 = 1.00395 times
Therefore the surface area of the star is approximately 1.004 times larger than the earth's surface area

Answer:
The answer is
[tex] {p}^{ - m - n} [/tex]Step-by-step explanation:
[tex] \frac{ {p}^{ - m} }{ {p}^{n} } [/tex]Using the rules of indices.
Since the bases are the same and are dividing we subtract the exponents
That's
[tex] \frac{ {x}^{y} }{ {x}^{z} } = {x}^{y - z} [/tex]So from the question we have

Three copies of this rectangle were connected along a side to make a larger rectangle. What could the perimeter of the new rectangle be? Consider all possibilities.
Answer:
388in or 202in
Step-by-step explanation:
I decided to connect three copies of this rectangle, all along the right side of the rectangle in the picture above.
When this is done the new length along the bottom and top become 45×4=180.
Now to find the perimeter, 180+180+14+14=388in
Other possibility
Connect the three copies along the top.
Now we need to do 14×4=56, which is the new side length.
Now to find the perimeter, 56+56+45+45=202in
which point is the midpoint of AE
Point D is the midpoint of points A and E for the given number line.
What is a number line?A number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.
A horizontal number line is the most common representation and can be extended infinitely in any direction.
Given the number lines with labeled points as A, B, C, D, and E.
The midpoint of AE is the mean of AE
Mean of AE ;
(A + E )/ 2 = (- 6 + 8) / 2
2 / 2 = 1 which is point D
Therefore "D" will be the midpoint of A and E.
Hence "Point D is the midpoint of points A and E for the given number line".

For the next inequality line at y = -5, we have;
1) The inequality line, starts with an open circle on the left at x = -3, which is equivalent to less than or equal to symbol, ≤ as -3 ≤ x because the point x =-3 is the left boundary. The inequality line extends to the point x = 2, where we have a closed circle (on the right), which is equivalent to a x ≤ 2 with the 2 on the right hand side because, the 2 is the right boundary of the inequality
2) The inequality can be summarized as starting from x = -3 extends to x = 2
3) As stated in point 1) the point x = 3, we have -3 ≤ x and at point x = 2, we have x ≤ 3 which can be combined as -3 ≤ x < 2, to give;
{ -5 if x ∈ -3 ≤ x < 2

Answer:
1st box = [-4, -3]
2nd box = (-3, 2]
3rd box = (2, 5]
For f(x) = -2 we see that x is between -4 to -3 with closed endpoints.
So the interval will be [-4, -3].
For f(x) = -5 we see that x is between -3 to 2 with closed endpoint at 2 and open endpoints at -3.
So the interval will be (-3, 2].
For f(x) = 5 we see that x is between 2 to 5 with open endpoint at 2 and closed endpoint at 5.
So the interval will be (2, 5].

Adult tickets for a charity concert were $5 each. Students were admitted for $2 each. The charity concert
sold 700 tickets and made $3050. How many students attended the lecture?
Answer:
students 150
adult 550
Step-by-step explanation:
x + y = 700
5x + 2y = 3050
x = 700 - y
5(700 - y) + 2y = 3050
3500 - 5y + 2y = 3050
-3y + 3500 = 3050
-3y = 3050 - 3500
-3y = -450
y = -450 / -3
y = 150
x = 700 - y
x = 700 - 150
x = 550

Answer:
3.343481472 x 10^4
Step-by-step explanation:
11.6 a = 3.25 *
6.18 * = 2.5 #
Take the first equation and solve for *
11.6 a = 3.25 *
Divide each side by 3.25
11.6 a/3.25 = *
3.569230769 a = *
Substitute this into the second equation for *
6.18 (3.569230769 a) = 2.5 #
22.05784615 a = 2.5 #
Solve for a
Divide by 22.05784615
a = 2.5 # / 22.05784615
a = .113338355
We have 2.95 x 10 ^5 a
