what is the difference between multiplying fractions and adding/subtracting fractions? complete sentances please
Answer:
See Explanation!
Step-by-step explanation:
When multiplying fractions, you do not need a common denominator, and the entire fraction gets multiplied across, however when adding or subtracting fractions, you must have a common denominator, and then only compute the numerator, as the bases are already the same
The figures are similar. Find x
Answer:
x = 15
Step-by-step explanation:
The scale factor is 8:20, we need to set up a proportion
Setting up the proportion:
[tex] \frac{8}{20} = \frac{6}{x} [/tex]
cross-multiply
8x = 120
x = 15 | Divide both sides by 8

In a certain year, a magnitude 7.8 earthquake struck California. In another year, a magnitude 5.8 quake struck Kansas. How many times as intense as the Kansas quake was the California quake?
Answer:
The California quake was 1.34 times as intense as the Kansas quake.
Step-by-step explanation:
To find how many times as intense as Kansas (K) quake was the California (C) quake first, we need to find the ratio of intensity (I) between those earthquakes:
[tex] \frac{I_{C}}{I_{K}} = \frac{7.8}{5.8} = 1.34 [/tex]
Now, by multiplying the above number for the intensity of the Kansas quake we should have the intensity of the California quake:
[tex] I_{K} = 1.34*5.8 = 7.8 [/tex]
Therefore, the California quake was 1.34 times as intense as the Kansas quake.
I hope it helps you!

If f(0) = 2 sin 0 - cos 20, find f(pi/6)
Answer: 1/2
Step-by-step explanation:
f(Ф) = 2sin(Ф) - cos(2Ф)
f(pi/6) = 2sin(pi/6) - cos(pi/3)
Use the pi circle or a calculator
f(pi/6) = 2(1/2) - 1/2 = 1/2
One year ago, Lindsey deposited $250 into a savings
account. Her balance
deposited $250 into
now $253, Two years ago, Jenn
savings account Her balance is
now $257.50. Which account has the greater simple
interest rate? Explain,
Answer:
Jenns account has the greater simple interest rate.
Step-by-step explanation:
The formula for simple interest is:
A = P * ( 1 + r * t )
Where A is the final amount after investment, P is the initial amount, r is the rate of interest and t is the time periods.
For Lindsey:
253 = 250 * ( 1 + r * t )
Solve for r
r = ( 253/250 ) - 1 = 0.012
Lindsey simple interest was 1.2% annually
For Jenn:
257.50 = 250 * ( 1 + r * 2 )
r = ( 257.50/250 ) - 1 )/2 = 0.015
Jenn simple interest was 1.5% annually
Therefore Jenns account has the highest simple interest rate.
Answer:
Lindsay’s interest is $3 for one year. Using the formula for interest, I = prt, Lindsey’s money is earning at a rate of 1.2%. Jenn has earned $3.75 for one year. Her money is earning at a rate of 1.5%, which is a higher interest rate.

A number x increased by 6, and then sum is doubled
Using the compound interest formula, the "n" is what value when compounded annually?
Answer:
n=1
Step-by-step explanation:
N is the number of times per year
Annually would be one time per year so n =1
Answer:
If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

Need help please I would be grateful
Answer:
The correct answer is given by option A.
Step-by-step explanation:
A function is said to be increasing for intervals of x in which the values of y are increasing, that is, it trends upwards, and decreasing for intervals of x in which the values of y are decreasing, that is, it trends downwards.
In this question:
It trends upwards from the start, at negative infinity, until 0.
It trends downwards from 0, until the end, at positive infinity.
So the correct answer is given by option A.
