Ashton is depositing money into a checking account. After 3 months there is $120 in the account. After 6 months, there is $240 in the account. Determine the constant rate of change of the account.
Answers
The constant rate of change of the account is $40 or Increasing by $40 per month.
Step-by-step explanation:
Consider the provided information.
Joanne is depositing money into a bank account. After 3 months there is $120 in the account. After 6 months there is $240 in the account.
Rate of change is known as how one quantity change in relation to other.
The rate of change can be calculated as:
y2-y1/x2-x1
Now use the above formula to calculated the rate of change.
240 - 120/6-3
120/3
40
Hence, the constant rate of change of the account is $40 or Increasing by $40 per month.

Step-by-step explanation:
You have to set up a proportion for this!
Because ABC and PAQ are similar triangles (same angles and PQ || BC), you can assume that all the equivalent sides are proportional!
If you solve the proportion for x:
[tex]\frac{x}{40} =\frac{7}{35}[/tex]

k with be the number multiplied by 20 and then N will be the answer
The expression for the total amount she charged can be represented as A = 20n.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
For example 2x = 54
An expression is a mathematical proof of the equality of two mathematical expressions.
Given that,
She will charge $20 for every lawn
Number of lawns she mows = n
Total charge let's represent by A
Then,
A = 20n will be the correct expression.
Hence "The expression for the total amount she charged can be represented as A = 20n".

the 200th term of the arithmetic progression 10 97,94,91,.............is
Answers
Answer:
-500
Step-by-step explanation:
Given sequence;
97, 94, 91 ......
Unknown;
The 200th term of the sequence;
Solution:
Since we were given an arithmetic progression, we need to first find the common difference;
Common difference = second term - first term
= 94 - 97
= -3
To find the 200th term, we use the expression below;
Sn = a + (n-1)d
a is the first term
n is the nth term
d is the common difference
S₂₀₀ = 97 + (200 - 1 ) x -3 = -500
Determine if the product CA is defined. If the product is defined, state its dimensions. Do not calculate the product.
Answers
Answer:
The product can be calculated.
The resulting matrix will have 3 rows and 3 columns.
Step-by-step explanation:
Matrix multiplication
To find the product of two matrices is only possible when the number of columns of the first matrix is equal to the number of rows of the second matrix.
If X is the first matrix with dimensions (n x m) and Y is the second matrix with dimensions (m x p), the product XY is possible and the dimensions of the resulting matrix are (n x p).
Matrix A has two rows and three columns (2x3)
Matric C has three rows and two columns (3x2)
If we wanted to calculate the product CA, the number of columns of C must be equal to the number of rows of A.
Since both numbers are 2, the product can be calculated.
The resulting matrix will have 3 rows and 3 columns.

Given:
(2x⁵ + 3y⁴)(-4x² + 9y⁴)
Required:
Find an equivalent polynomial
Solution:
(2x⁵ + 3y⁴)(-4x² + 9y⁴)
Using distributive property of multiplication
2x⁵(-4x² + 9y⁴) + 3y⁴(-4x² + 9y⁴)
-8x⁷ + 18x⁵y⁴ - 12x²y⁴ + 27y⁸
There are no like terms to add or combine, therefore:
(2x⁵ + 3y⁴)(-4x² + 9y⁴) = -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸

A volunteer is buying 10 blankets for the animal shelter. Shipping the blankets will cost $12 and the volunteer has $75 total to spend. What is the maximum amount the volunteer can spend for each blanket? Write an inequality that would represent the situation and solve the inequality. Show your work to justify your answer.
Answers
Answer:
6.3
Step-by-step explanation:
10 blankets with an unidentified price plus 12 for shipping is equal to 75
10x+12=75
minus 12 from both sides
10x=63
divide 10 from both sides
x=6.3
Now, let's prove the answer is true.
10x+12=75
Replace x with 6.3
10(6.3)+12=75
10 times 6.3
63+12=75
75=75
The statement is true.

Answer:
The graph of g(x) has a lesser y intercept
Step-by-step explanation:
Given
f(x) = 100(-x + 4)
Required
Determine the relationship between f(x) and g(x)
First, we need to get the equation of g(x).
From the question, we have that:
Initial Value = 360
Rate = -90 yearly
[It is negative because the rate shows decrement]
Hence, the equation of g(x) is:
g(x) = Initial Value + Rate * x
Where x represents number of years
g(x) = 360 + (-90 * x)
g(x) = 360 - 90x
g(x) = -90x + 360
Recall that
f(x) = 100(-x + 4)
f(x) = -100x + 400
To solve y intercept, we set x = 0.
f(0) = -100 * 0 + 400 = 0 + 400 = 400
g(0) = -90 * 0 + 360 = 0 + 360 = 360
By comparison, the graph of g(x) has a lesser y intercept
To solve x intercept, we set y = 0
For f(x)
0 = -100x + 400
100x = 400
x = 4
For g(x)
0 = -90x + 360
90x = 360
x = 4
By comparison, they have the same x intercepts.

In a survey, of the voters support a particular referendum. If 40 voters are chosen at random, find the mean and variance for the number of voters who support the referendum.
Answers
This question is incomplete, the complete question is;
In a survey, 55% of the voters support a particular referendum. If 40 voters are chosen at random,
find the mean and variance for the number of voters who support the referendum.
Answer:
a) The Mean is 22
b) Variance is 9.9
Step-by-step explanation:
Given that;
55% of the voters support a particular referendum p = 0.55
q = 1 - p = 1 - 0.55 = 0.45
sample size n = 40
a)
Mean = sample size n × p
Mean = 40 × 0.55
Mean = 22
Therefore the Mean is 22
b)
Variance = n × p × q
so we substitute
Variance = 40 × 0.55 × 0.45
Variance = 9.9
Therefore the Variance is 9.9

Steve ran for class president against Mandy. Steve received 5 votes for every 3 votes that Mandy received. Mandy received 420 votes. If all the students only voted once?how many students voted in the election? Pls help ASAP!!
Answers
Answer:
1120
Step-by-step explanation:
The ratio Steve : Mandy is 5 : 3.
We use a proportion to find the number of votes Steve received.
x = number of votes Steve received.
5/3 = x/420
3x = 5 * 420
x = 5 * 140
x = 700
Steve received 700 votes.
The total number of votes is the sum of the votes Steve receive and Mandy received.
420 + 700 = 1120
A painter uses 1.2 liters of the paint to cover 1m2 of the wall.
How many square meters he can cover with 6.6 liters of paint?
Answers
12)/1.2=120/12=10m^2
4.8/1.2=48/12=4m^2
6.6/1.2=66/12=11/2=5.5m^2
this is another way you can do it
1. 12/1.2 times as much paint, so 12/1.2 times as much area.
2. 6.6/1.2 times as much paint, so 6.6/1.2 times as much area.
3. 4.8/1.2 times as much paint, so 4.8/1.2 times as much area.
