Answer: 7m - 40
Step-by-step explanation:
Monday = m
Tuesday = m + 15
Wednesday = m + 15 + 30 = m + 45
Thursday = 2 × m = 2m
Friday = 2m - 20
The expression will now be:
= m + m + 15 + m + 45 + 2m + 2m - 20
= 7m- 40

Step-by-step explanation:
suppose you plunk $5000 into a one-year certificate of deposit (CD) that pays simple interest at 3% per annum. The interest you earn after one year would be $150:
The simple interest for a deposit of $ 5,000 at 3 % rate of interest for 1 year would be $ 150
What is Simple Interest?
Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Given data ,
Let the simple interest be represented as S
Now , the value of S is
The principal amount = $ 5,000
The rate of interest R = 3 %
The time period T = 1 year
So , the Simple Interest is given by the equation
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Substituting the values in the equation , we get
Simple Interest S = ( 5000 x 3 x 1 ) / 100
On simplifying the equation , we get
Simple Interest S = 150000 / 100
Simple Interest S = $ 150
Therefore , the value of S is $ 150
Hence , the simple interest for the deposit is $ 150

A dog walking service offer daily services in weekly service in the winter the ratio decor Shmurda weekly customer was 125 however in Springmore Cozumel motivate the daily service because of all the nice weather out of the chair while change the ratio was 4 to 2 if there was a 125 weekly? In the winter how many dell customer would it be in the spring
Answer:
100 customers
Step-by-step explanation:
The computation of the number of dell customers would be in the spring is shown below:
Given that
In winter season
The ratio of daily customers to weekly customers = 1:5.
In Spring season :
The ratio of daily customers to weekly customers = 4:2.
And, the Number of the weekly customer in the winter is 125
So if we can see that the weekly customers would be 5 times of daily customers
So, the daily customers in winter is
= 125 ÷ 5
= 25 customers
Now in the spring it would be
= 25 × 4
= 100 customers

A sum amount to $2400 at 15% simple interest per annum after 4 years. Find the sum
Answer:
1500
Step-by-step explanation:
We can required to find the sum which also means the value
Future value= value × [ 1 + rate×time]
2400= value × [1 + 15/100×4]
2400= value × [1 + 0.15×4]
2400= value × [1+0.6]
2400= value × 1.6
Value= 2400/1.6
= 1500

Answer:7
Step-by-step explanation: x+5=12 solve for x = 7
Answer:
"a number" = 7
Step-by-step explanation:
let "a number" = x.
x + 5 = 12
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Subtract 5 from both sides.
x + 5 (-5) = 12 (-5)
x = 12 - 5
x = 7

Your parents are building a pool that is 7 ft wide and 12 ft long. They want to put a walkway around the pool that is x ft wide on all sides. Write a polynomial that represents the combined area of the pool and walkway. Answer needs to be in standard form and use x as your variable.
Answer:
Combined area = 4[tex]x^{2}[/tex] + 38x + 84
Step-by-step explanation:
The rectangle formed by the pool and walkway is 12 + 2x long and 7 + 2x wide.
Area of the rectangle = lw = (2x + 12)(2x + 7) = 4[tex]x^{2}[/tex] + 38x + 84

y=(2/7)x-16/7 subtract 2 from both sides, 2=14/7

Consider the polynomial function q(x) = 3x^4 – 5x^3 – 2x^2 + x – 18.
What is the end behavior of the graph of q?
Answer:
a in the picture
Step-by-step explanation:
The end behaviour of the function is correctly represented by option 1.
What is the end behaviour of a function? What do you mean by domain and range of a function?The end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).
For any function y = f(x), Domain is the set of all possible values of [x] for which [y] exists. Range is the set of all values of [y] that exists for the given domain.
Given is the following function polynomial as -
q(x) = 3x⁴ – 5x³ – 2x² + x – 18
The given polynomial is -
q(x) = 3x⁴ – 5x³ – 2x² + x – 18
Graph the function. It can be seen that the domain is limited from -
x = -1.365 to x = 2.351 which is a small value. So, we can predict the end behaviour of the graph as given in option [1].
Hence, the end behaviour of the function is correctly represented by option 1.

Answer:
P(-6)
Step-by-step explanation:
1.P (-6) 2. Q (-2) 3. R (1) 4. S (5)
The absolute value of a number disregards ir removed the negative sign from the number and treats as positive.
The absolute value of the numbers given in the option above :
P(-6) = |6|
Q(-2) = |2|
R(1) = |1|
S(5) = |5|
Hence, the option which has the greatest absolute value when arranged on a number line is |6|

Select the equation that represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.
Step-by-step explanation:
25m + 10b = 400
not enough info to solve for m or b. but that's the equation you would use.
