A and b are positive integers and a-b=2. Evaluate the following:
(27^1/3b)/ ( 9^1/2a)
(this is urgent)
(I have tried 1, 25, and 1/27. None of them are correct)
Answer:
[tex]\displaystyle\displaystyle \frac{27^{1/3b}}{9^{1/2a}}=\frac{1}{9}[/tex]
Step-by-step explanation:
We are given that a and b are positive integers such that:
[tex]a-b=2[/tex]
And we want to evaluate:
[tex]\displaystyle \frac{27^{1/3b}}{9^{1/2a}}[/tex]
First, note that 27 = 3³ and that 9 = 3². Therefore:
[tex]\displaystyle =\frac{(3^3)^{1/3b}}{(3^2)^{1/2a}}[/tex]
Simplify:
[tex]=\displaystyle \frac{3^b}{3^a}[/tex]
Using the quotient property of exponents:
[tex]=3^{b-a}[/tex]
From our given equation, we can divide both sides by -1 to acquire:
[tex]-a+b=-2\text{ or } b-a=-2[/tex]
Therefore:
[tex]=3^{-2}[/tex]
Hence, our answer is:
[tex]\displaystyle\displaystyle \frac{27^{1/3b}}{9^{1/2a}} =\frac{1}{3^2}=\frac{1}{9}[/tex]

A cereal box has a height of 10 inches, a length of 8 inches, and a width of 2 inches. What is the surface area of the cereal box?
Answer:
232 in^2
Step-by-step explanation:
Using the formula for surface area A=2(wl+hl+hw)
A=2(16+80+20)
A=232
The surface area of the cereal box is 232 square inches
What is the surface area of cuboid?The surface area of a cuboid is the total area of all its surfaces. Since a cuboid is a three-dimensional solid shape, the value of its surface area depends on the dimensions of its length, width, and height. The change in any of the dimensions of a cuboid changes the value of the surface area of a cuboid. The surface area of a cuboid is expressed in square units.
Total Surface Area of Cuboid
= 2 (length*width + width*height + length*height)
According to the question
A cereal box has a height = 10 inches
A cereal box has a length = 8 inches
A cereal box has a width = 2 inches
Now ,
Applying the formula of Total Surface Area of Cuboid as cereal box is also a cuboid
Total Surface Area of Cuboid
= 2 (length*width + width*height + length*height)
substituting the values
Total Surface Area of Cuboid
= 2 (8*2 + 2*10 + 8*10)
= 2 (16 + 20 + 80)
= 2(116)
= 232 square inches
Hence, the surface area of the cereal box is 232 square inches

Aiden invested $98,000 in an account paying an interest rate of 2 % compounded
continuously. Autumn invested $98,000 in an account paying an interest rate of 2%
compounded quarterly. After 11 years, how much more money would Autumn have in
her account than Aiden, to the nearest dollar?
Answer:
Aiden would have $67 more than Autumn.
Step-by-step explanation:
Aiden compounded continuously, which uses the formula: [tex]P(t)=P_oe^r^t[/tex]
Plugging in what we know about Aiden's investment: [tex]P(11)=98000e^0^.^0^2^*^1^1[/tex]
That gives us: 122115.5196
Autumn invested using regular compound interest, which has the formula: [tex]A=P(1+\frac{r}{t})^n^t[/tex]
Since Autumn's investment is getting compounded quarterly, n=4 because it gets compounded 4 times a year.
Plug in Autumn's investment: [tex]A=98000(1+\frac{0.02}{4})^4^*^1^1[/tex]
That gives us: 122048.5974
Now just subtract the two and round to the nearest dollar:
[tex]122115.5196-122048.5974=66.92215187[/tex]
OR
$67. Aiden would have $67 more than Autumn after 11 years.
37 1/2 of what number is 60
37.5 is 60% of 62.5#
Explanation:
First, let's call the number we are looking for
n
.
"Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as
60

When dealing with percents the word "of" means "times" or "to multiply".

Hi!
So to find out the slope, we can use the equation change in y value over change in x value -- or vertical change over horizontal change.
Find two points on the graph that line up exactly on the lines of the graph, like (20, 0) and (12, 0).
Then, take the change in y value (20-0 = 20) and divide it by the change in x value (0 - 12) to get -20/12, or -5/3.

Answer:
Las longitudes que se forman entre los vértices y el centro de un polígono regular son;
Los radios del círculo circunscrito
Step-by-step explanation:
Cada círculo de radio, 'r', tiene un polígono que se puede inscribir polígono regular que tiene 'n' lados, donde n ≥ 3 y viceversa, todos los polígonos regulares se pueden inscribir (dibujar) en un círculo, que luego se conoce como la circunferencia del polígono
Dado que un polígono regular se puede inscribir en un círculo, de modo que sus vértices descansen sobre la circunferencia del círculo, entonces el centro del polígono es el centro del círculo que lo circunscribe.
Por lo tanto, las longitudes (iguales) que se forman entre los vértices y el centro del polígono regular son el radio del círculo que lo circunscribe..

Answer:
See explaination and answer below
Step-by-step explanation:
Relationship:
Complementary angles add up to 90 degrees
JKL + MNP = 90
Solve for x:
(2x - 3) + (5x + 2) = 90
7x - 1 = 90
7x = 91
x = 13
Solve for JKL:
JKL = 2x - 3
JKL = 2(13) - 3
JKL = 23 degrees
Solve for MNP:
MNP = 5x + 2
MNP = 5(13) + 2
