=================================================
Explanation:
When you multiply fractions, you multiply the numerators together. So in this case we multiply 3 and 3 getting 9 as the updated numerator.
We also multiply the denominators together. The updated denominator is 4*5 = 20.
Overall, (3/4)*(3/5) = (3*3)/(4*5) = 9/20
The fraction 9/20 cannot be reduced because 9 and 20 do not have any common factors other than 1.
We don't have to worry about getting the LCD (lowest common denominator) since that is only applicable for adding and subtracting fractions.

Arithmetic and geometric sequences plato/edumentuM
Answer:
A
Step-by-step explanation:
every term of the sequence is created by multiplying the previous term by -2.4
to get the ratio (or multiplication factor) of the sequence :
4 × r = -9.6
r = -9.6/4 = -2.4
and as you can easily check, the following y values use the same factor.
so, as multiplication is used, it is a geometric sequence.
if addition were used, it would be an arithmetic sequence.
but the differences between the y values are clearly not constant (as it would be, if we added a fixed constant to every term to create the next).
so, B and D are automatically wrong.
and C is wrong, because the given ratio or multiplication factor cannot be right :
4 × 0.4 = 1.6 and never -9.6
Here’s an algebra problem 20 points will mark brainliest if correct!!!
Answer:
y = 12/7xStep-by-step explanation:
Given A graph with points A, B, C, D and ETo findEquation of the line through the points C and DSolutionWe'll get the coordinates of the points C and D first and find slope and y-intercept
As per the graph, the coordinates are:
C = (0, 0) and D (7, 12)Formula of the line
y = mx + bSlope is
m = (12 - 0)/(7 - 0) = 12/7y- intercept is 0 as per point CSo the line is
y = 12/7xI’m backkkkkkkk

Find the sum of
Crystal said she used the distributive property to evaluate 5(4 + 7). These are the steps she took:
5(4 + 7) = 5⋅4 + 7 = 20 + 7 = 27
What mistake did Crystal make? What is the correct answer to 5(4 + 7)?
Type a paragraph
Answer:
Crystal's mistake was that she distributed the 5 only to the 4, not to the 7 as well.
The correct step should have been 5(4 + 7) = 5⋅4 + 5⋅7.
Using the distributive property correctly would give the sum of the two products, 20 + 35. The value of 5(4 + 7) is 55.
The value of 5(4 + 7) is 55.
It is required to find the correct answer.
What is simplification?Simplification means simplifying processes involved in work towards consistency of efforts, costs and time. It eliminates useless and disadvantageous (or unnecessary) diversity and variety.
Given that:
By the Distributive Property
If a, b, c are real numbers, then
a*(b+c)=a*b+a*c
Crystal's did mistake was that she distributed the 5 only to the 4, not to the 5 to 7 as well.
First distribute and then multiply, we get
The correct step should have been
= 5(4 + 7)
= 5⋅4 + 5⋅7.
= 20 + 35.
= 55
Therefore, the value of 5(4 + 7) is 55.

i Just need the graph points
Answer:
Step-by-step explanation:
In the graph, y is the amount of sand in mm^3 and x is time in seconds.
They are directly related as the sands drops at a constant rate of 2.5 cubic millimeters ( mm^3 ) every second.
So y = 2.5x
Input x=0, output is y=0
The first point is (0, 0)
Input x=2, y=2.5*2=5
The second point is (2, 5)
Input x=6, y=2.5*6=15
The third point is (6, 15)
You are at a trade show where you are selling baseball cards for $4 a card and buying baseball cards for $6 a card. If you started the day with $200, how much money do you have at the end of the day if you sold c baseball cards and bought b baseball cards?
Answer:
200 +4c -6b
Step-by-step explanation:
Your ending balance is the sum of your beginning balance plus sales, less your purchases. If each sale nets $4, then c sales will increase your balance by 4c. If each purchase costs $6, then b purchases will reduce your balance by 6b.
Your ending balance is ...

After four years of college, Erica has to start paying off all her student loans. Her first payment is due at the end of this month. Her bank told her that she has 7 years to pay off all of her loans, and that starting this month, the loans will be compounded monthly at a fixed annual rate of 9.1%. Erica currently has a total of $34,006.00 in student loans. Use the formula for the sum of a finite geometric sequence to determine Erica's approximate monthly payment.
Answer:
Therefore, the approximate monthly payment is $548.85
Step-by-step explanation:
The amount of student loans Erica currently has = $34,006.00
The duration over which Erica is to pay back the loan = 7 years
The annual interest rate for the loan = 9.1%
Therefore, we have the geometric sequence formula is given as follows;
[tex]A_n = P( 1 + r)^n - M \times \left [ \dfrac{(1 + r)^n-1}{r} \right ][/tex]
Where;
M = The monthly payment
P = The initial loan balance = $34,006.00
r = The annual interest rate = 9.1%
n = The number of monthly payment = 7 × 12 = 84
Aₙ = The amount remaining= 0 at the end of the given time for payment
Substituting the values into the above formula, , we get;
[tex]0 = 34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} - M \times \left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ][/tex]
[tex]M = \dfrac{34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} }{\left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ]} \approx 548.85[/tex]
Therefore, the approximate monthly payment = $548.85

Han ran 10 meters in 2.7 seconds. Priya ran 10 meters in 2.4 seconds. How long would it take han to run 50 meters.
Hans would take 13.5 seconds to run 50 meters
Priya would take 12 seconds to run 50 meters
--------------------------------------------------------------------------------
Since they each ran 10 meters for a certain amount of time you would multiply the seconds by 5 since 10x5=50
When you do that you get
13.5 for Han's time by multiplying 2.7x5=13.5
and
12 seconds for Priya's time by multiplying 2.4x5

The modified expression, x3(2x 5) – 4(2x 5), has two terms with a common factor of.
Answer:
Step-by-step explanation:
You need to use the distributive property to take out the common factor. But that doesn't tell you what the common factor is.
Look inside the brackets. You need to find something that is exactly the same on either side of the minus sign. In this case you have a huge cle about what it is.
2x^5 is it not? I'm assuming that's the correct way to read it.
So that's the answer to your question 2x^5.
The distributive property will tell you that 2x^5 can be taken out, and what is left is
2x^5 ( x^3 - 4)

If angle X and angle Y are a Linear Pair, what can be stated about the two angles?
A. Angle X and angle Y are both obtuse
B. Angle X and angle Y are complementary
C. Angle X and angle Y are supplementary
Answer:
C
Step-by-step explanation:
linear pairs equal up to 180°, so the 2 angles must be supplementary, meaning it adds up to 180°.

Find the sum of the interior angles of a polygon with 20 sides
Answer:
3240°
Step-by-step explanation:
The sum of the interior angles of a polygon is found by (n-2)(180) where n is the number of sides so (20-2)(180) = (18)(180) = 3240°
Is this sequence arithmetic or geometric? And what is the equation? 301, 358, 415, 472…
Answer:
a_n = 244 + 57n, for n ≥ 1
Step-by-step explanation:
358 - 301 = 57
415 - 358 = 57
472 - 415 = 57
There is a constant difference, so the sequence is arithmetic.
a_1 = 301
a_2 = 358 = a_1 + 57
a_3 = 415 = a_1 + 57 × 2
a_4 = 472 = a_1 + 57 × 3
a_n = a_1 + 57 × (n - 1)
a_n = 301 + 57(n - 1)
a+n = 301 + 57n - 57
a_n = 244 + 57n, for n ≥ 1
