Answer:
To multiply radicals with different indices, we need to find a common denominator, which is the lowest common multiple (LCM) between the roots. Once we obtain the LCM, we can multiply each root and exponent in the radicand to obtain the LCM, and rewrite as one radical
When we multiply two radicals with the same type of root (both square roots, both cube roots, and so on), we simply multiply the radicands (the expressions under the radical signs) and put the product under a radical sign
Anna's cars can travel to 8 miles on 6 gallons of gas write an equation to represent the distance y and mild and car driven on x gallons of gas
Answer:
a. [tex]y=38x[/tex].
Step-by-step explanation:
Let y represent distance in miles and x represent gallons of gas.
a. First of all, we will find mileage of Ann's car by dividing total distance traveled by total fuel consumed.
Mileage of Ann's Car: [tex]=\frac{228 miles}{6 gallons}[/tex]Mileage of Ann's Car:[tex]=\frac{38 miles}{gallon}[/tex]Since Ann's can travels 38 miles per gallon, so distance covered by using x gallons on gas would be [tex]38x[/tex] .
Therefore, our required equation would be [tex]y=38x[/tex].

Canon borrows $3,000 at a yearly simple interest rates of 1.6% for 2 years how much does he owe in interest and how much does he need to pay back in all
Interest is Rs.96 and Total amount payback is Rs.3096.
Principal (P) = Rs.3000
Rate of interest (R) = 1.6%
Number of years (N) = 2 yrs
Simple interest = PNR/100
= (3000*1.6*2)/100
=(9600/100
=96Rs
Total Amount (A) = P+I
=3000+96
=3096Rs
The principal, or initial balance of your account, is where interest is calculated. This could be the initial sum of a loan or an investment. The simplest way to compute interest is as a percentage of the principal .Only relatively short-term loans frequently include one-time basic interest charges. Interest is frequently paid on a daily, monthly, quarterly, or annual basis for loans with longer terms. In that scenario, interest would be consistently earned.
Hence, the interest for the above principle is 96Rs and the total amount to be payback is 3096Rs.

Edgar and Paul are playing video games. Edgar's score is 160 and he scores 5 points per second. Raul's score is 100 and he
scores 8 points per second. How long will it be before Raul takes the lead?
Answer:
21 seconds
Step-by-step explanation:
First let's find out how long it would take for them to have the same score.
160 + 5s = 100 + 8s
160 = 100 + 3s
60 = 3s
20 = s
Since it takes 20 seconds to get the same score and Raul get's more points every second, it would take 21 seconds for Raul to take the lead.

In a shipment of 53 vials, only 13 do not have hairline cracks. if you randomly select 2 vials from the shipment, what is the probability that none of the 2 vials have hairline cracks?
Calculating the likelihood of experiments happening is one of the branches of mathematics named as probability. The probability that none of the 2 vials have hairline cracks is 0.0565.
What is meant by probability?The study of probabilities, which exists defined by the ratio of favorable occurrences to probable cases, exists comprehended as probability.
The probability that there won't be any hairline cracks = 13/53
If you choose two vials at random from the delivery
Probability (avoiding hairline cracks) = 13 - 1/53 - 1
Probability (avoiding hairline cracks) = 12/52
To find the chance that neither of the two vials has a hairline crack is

(2,58),(6,105),(8,88),(8,118),(12,117), , (16,137),(20,157),(20,169)
A scatter plot is a series of points plotted on horizontal and vertical axes. If there is no correlation between variables, the points appear randomly scattered on the coordinate plane. The points will be clustered around a straight line if the correlation is high. A scatter chart is a data visualization tool that helps show trends.
The scatter plot shows not only the magnitude of the correlation but also the direction of the correlation.
As the vertical (or Y-axis) variable increases, the correlation is positive as the horizontal (or X-axis) variable increases.
The correlation is negative if the y-axis variable decreases and the x-axis variable increases, or vice versa.
The correlation is zero if none of the above criteria can be established.

How to determine the family of constants associated to non-real roots of a quadratic equation
The nature of the roots of quadratic equations of the form a · x² + b · x + c = 0 can be inferred by the understading of its discriminant under the following condition:
b² - 4 · a · c < 0
Where a, b, c are the coefficients of the polynomial.
If we know that a = 2 · q, b = q and c = - 1, then the equation of the discriminant is:

The density of the material is 0.4 kg/cubic cm.
Given that:-
Height of the cylinder = 54.5 mm
Diameter of the cylinder = 53.0 mm
Weight of the cylinder = 1 kg
We have to find the density of the cylinder.
We know that,
Density = mass/volume
Here, mass = 1 kg
We know that,
Volume of a cylinder = [tex]\frac{1}{3} \pi r^2 h[/tex]
Where,
r is the radius of the cylinder, and
h is the height of the cylinder
Here, h = 54.5 mm, and
r = 53/2 = 26.5 mm
Hence,
Volume of cylinder = (1/3)*(22/7)*(26.5)(26.5)*54.5 ≈ 2566.088 ≈ 2566 cubic mm. = 2566/(10*10*10) cubic cm = 2.566 cubic cm

A regulation volleyball has a circumference of about 66 centimeters. The ratio of the surface area of that ball to the surface area of a children's ball is approximately 1.6: 1 . What is the circumference of the children's ball? Round to the nearest centimeter.
The circumference of the children's ball to the nearest centimeter is 52 centimeters.
If a regulation volleyball has a circumference of about 66 centimeters, solve for its radius using the formula for the circumference of a circle given by:
C = 2πr
66 centimeters = 2πr
r = 33/π centimeters
Then, solve for the surface area of this regulation volleyball using the formula given by:
A = 4πr^2
A = 4π(33/π centimeters)^2
A = 4356/π square centimeters
If the ratio of the surface area of that ball to the surface area of a children's ball is approximately 1.6 : 1, then
surface area of regulation volleyball : surface area of a children's ball = 1.6 : 1
surface area of a children's ball = 4356/π square centimeters/1.6
surface area of a children's ball = 2722.5/π square centimeters
If the children's ball has a surface area of 2722.5/π square centimeters, solve for its radius using the formula for the surface area given by:
A = 4πr^2
2722.5/π square centimeters = 4πr^2
r = 26.0887907/π centimeters
Solving for the circumference:
C = 2πr
C = 2π(26.0887907/π centimeters)
C = 52.17758139 centimeters
