[tex]\bold{\displaystyle\frac{144}{169}}[/tex]
So what number times itself equals [tex]\bf{\displaystyle\frac{144}{169}}[/tex]?
Take the square root of both the numerator (144) and the denominator (169)
[tex]\bold{\sqrt{\displaystyle\frac{144}{169} }}[/tex]
The square root of 144 is 12 (12 times itself equals 144), and the square root of 169 is 13 (13 times itself equals 169)
[tex]\bold{\displaystyle\frac{12}{13}}[/tex]

find the volume of a cylinder with base diameter 140cm and height 10cm. (22/7)
Step-by-step explanation:
could not find the formula ?
the volume of a cylinder is ground area × height.
and the ground area is a circle.
so, all in all we get
pi×r²×h
with r being the radius (half of the diameter), and h being the height.
in our case we get
pi×(140/2)²×10 = pi×70²×10 = 49000×pi =

express the product of 0.54 and 0.35 in standard form
Answer:
First answer, 0.54 is 54% and for the second one, 0.35 is 35%
Step-by-step explanation:
1. You first mulitply the numerator by the denominator by 100 which would be 0.54 x 100 = 54
2. Once you get the answer you just add a percentage to the end of 54 which would equal 54% and thats your answer for 0.54 and to find 0.35 it is the same thing to find the percentage.

The data is modeling a geometric sequence because they have a common ratio of 2.
Part B:
= 48
Step by Step Answer
f(n)=f(n-1)*r
f(n)=f(5-1)*2
f(n)=f(4)*2
f(n)=(24)2
f(n)= 48
Part C:

Step by Step Answer
f(n)=f(1)*r^n-1
f(n)=3*2^8-1
f(n)=3*2^7
f(n)=3*128
f(n)=384
Aurora will complete the 10th station in 1024 minutes (or 17 hours and 4 minutes).
What is a geometric sequence?A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding terms. This ratio is regarded as one of the geometric sequence's common ratios.
aₙ=a₁(r)ⁿ⁻¹
The given data represents a geometric sequence, where the common ratio between any two consecutive terms is 2.
We can find the common ratio by dividing any term by its preceding term.
Common ratio = 4/2 = 8/4 = 16/8 = 2
Let T₁ be the time taken to complete the first station (x = 1). Then the explicit formula for the nth term of the geometric sequence is:
Tₙ = T₁ r⁽ⁿ⁻¹⁾
where r is the common ratio.
We are given the first four terms:
T₁ = 2
T₂ = 4
T₃ = 8
T₄ = 16
We can use the formula to find the time taken to complete the 10th station (x = 10):
T₁₀ = T₁ r⁽¹⁰⁻¹⁾
T₁₀ = 2(2)⁹
T₁₀ = 2 x 512
T₁₀ = 1024
Therefore, T₁₀ = 1024.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Evelyn needs to order some new supplies for the restaurant where she works. the restaurant needs at least 309 forks. there are currently 226 forks.
Let x be the minimum number of sets of forks Evelyn should buy.
The value of x can be found as follows:
x = (309 - 226)/10
x = 83/10
x = 8.3 = 9 (because the restaurant needs at least 309 forks)
Thus, the number of sets of forks Evelyn should buy is 9 if Evelyn needs to order some new supplies for the restaurant where she works.

Can someone explain how to simplify radicals? (Please leave an example) Im so confused!!
Answer:
Sure!
Step-by-step explanation:
So a radical(or a root) is the opposite of the exponent(for example square root is the opposite of the square of a number). Graphically it's not but it's more simple to think of it like that. Simplifying integer radicals is simple. For example, the square of 11 is 121, so sqr121 (√121) is equal to 11. Other radicals/powers are similar. cuberoot27= 3 because 3^3 is 27. If you add variables, the same thing happens. You can think of the √ as a funnel where only the numbers "big enough" can leave. If you have √xy^2z^3,
the x would have to stay because it's only to the first power, the √y^2 would be reduced to just y, and one pair of zs can come out resulting in z√z. The final answer to √xy^2z^3 would be yz√xz. Hope that helps :)

Answer:

Step-by-step explanation:
The initial investment of Calvin must be increased by a factor of 115.927 % to equal Marquez's investment at any time. (Correct choice: D)
How to determine the investment needed by Calvin to equal Marquez's investment at any time
In this question we must apply the concept of compound interest to derive the initial investment to be done by Calvin. According to the statement, Calvin invests money five years later than Marquez.
To determine the initial investment to be deposited by Calvin such that his investment equals Marquez's investment at any time we resort to the following expression:
[tex]1500\cdot (1+0.03)^{t+5} = C_{C}\cdot (1+0.03)^{t}[/tex] (1)
Then, we simplify the required initial investment:
[tex]C_{C} = 1500\cdot (1+0.03)^{5}[/tex]
[tex]C_{C} = 1738.911[/tex]
And the increase factor is:
[tex]r_{C} = \frac{1738.911}{1500}\times 100\,\%[/tex]
[tex]r_{C} = 115.927\,\%[/tex]
The initial investment of Calvin must be increased by a factor of 115.927 % to equal Marquez's investment at any time. (Correct choice: D) [tex]\blacksquare[/tex]

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer: x = 54°
Step-by-step explanation:
The sum of these three inter angles is equal to 180°.
36° + 90° + x° = 180
126 + x = 180
x = 54°
Step-by-step explanation:
36° +90°+ x = 180° ( sum of all angle of triangle is 180°)
126° + x = 180°
x = 180° - 126°
x = 54°
