Rahul's monthly income is * 25,000, out of
which he spends 20% on accommodation,
50% on household expenditure, 15% on
transportation and the rest is saved. How
much money does he save?
Answer:
3750
Step-by-step explanation:
25,000 = 100%
20% accomodation
50% household
15% transportation
Saved=100%-20%-50%-15%=15% left saved
15% of 25,000=3750
_______________________________
= 20% + 50% + 15%= 85%= 85% × $25,000 ÷ 100= $21,250= $25,000 - $21,250= $3,750RAHUL SAVES $3,750 EVERY MONTH_______________________________
Claire and Malia are training for a race.
a. Claire runs 10 km in 1 hour. How many kilometers does she run in half an hour? in 2 1/2 hours?
b. Malia runs 5 miles in 1 hour. How many miles does she run in half an hour? in 2 1/2 hours?
c. On Tuesday, Claire and Malia both ran for 2 1/2 hours. Who ran the farther distance?
Answer: hello ima say first off Malia is my name lucky me my name is being used but for more serious matters... hope this helpssss
b)Claire runs 10km in 1 hour. In 2-1/2 hours, she runs (2-1/2 x 10) = 25 km.
c) Malia runs 5 miles in 1 hour
Step-by-step explanation:
The unit rate for 65 miles in 2.7 gallons is___ miles per gallon. (Round your answer to the nearest hundredths)
Answer:
The unit rate for 65 miles in 2.7 gallons is 24.07 miles per gallon.
Step-by-step explanation:
Given that:
65 miles in 2.7 gallons
We have to find the unit rate.
Unit rate is a rate to compare quantities in which one quantity is 1.
Unit rate = [tex]\frac{65}{2.7}[/tex]
Unit rate = 24.07 miles per gallon.
Hence,
The unit rate for 65 miles in 2.7 gallons is 24.07 miles per gallon.
A rectangular field is 10m longer than wide. The area of the field is 2000m². Find the perimeter of the field.
Answer:
180m
Step-by-step explanation:
Let L = length of field,
W = width of field,
A = field area = 2000 m^2
Lenght = Width + 10m
Let Lenght= x
Width=y
A = X ×Y = (Y + 10)Y= 2000
Y^2 + 10Y- 2000 = 0
Solving using Quadratic eqn with plot
Y= 40 or -50 but we go for the positive root
Width=40m
Length= 40m +10m
= 50m
Perimeter= 2(l+w)
=2(50+40)
180m
Hence, the perimeter is 180 m

Bonnie's favorite game at the arcade is Can Em Down. In the game, players earn 7 points for each can they knock down. Bonnie earned 84 points in her best game. Let c represent how many cans Bonnie knocked down. Which equation models the problem?
Answer:
c = (total points earned in best game / points per can knocked down)
c = 12
Step-by-step explanation:
Given that :
Points earned per knockdown = 7
Total points earned in best game = 84
Number of cans knocked down, c
c = (total points earned in best game / points per can knocked down)
c = 84/ 7
c = 12

how do you factor 3y^3 - y^2 -9y + 3
Answer:
(3y - 1)(y - √3)(y + √3)
Step-by-step explanation:
Factor by grouping.
3y³ - y² - 9y + 3
= (3y³ - y²) - (9y - 3)
= y²(3y - 1) - 3(3y - 1)
= (3y - 1)(y² - 3)
= (3y - 1)(y - √3)(y + √3)

Answer:
We conclude that the rule for the table in terms of x and y is:
y = 3x+2Step-by-step explanation:
The table indicates that there is constant change in the x and y values, meaning the table represents the linear function the graph of which would be a straight line.
We know the slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept.
Taking two points
(-2, -4)(-1, -1)Finding the slope between (-2, -4) and (-1, -1)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-1\right)[/tex]
[tex]m=\frac{-1-\left(-4\right)}{-1-\left(-2\right)}[/tex]
[tex]m=3[/tex]
We know that the y-intercept can be determined by setting x = 0 and finding the corresponding y-value.
Taking another point (0, 2) from the table.
It means at x = 0, y = 2.
Thus, the y-intercept b = 2
Using the slope-intercept form of the linear line function
y = mx+b
substituting m = 3 and b = 2
y = 3x+2
Therefore, we conclude that the rule for the table in terms of x and y is:
y = 3x+2The equation A=p+prt is ued to find the accumulated amount, A, of an investment with principle, P, a certain interest rate, r, and over time, t. What is the value for r, after the equation is rearranged?
A. r= A+p/ pt
B. r= A-p/ pt
C. r= A-1/ t
D. r= A-p-pt
Answer:
B. r = A-p/pt
Step-by-step explanation:
We can rearrange the equation to make [tex]r[/tex] the subject of the equation:
[tex]A=p+prt[/tex]
[tex]A-p = p+prt-p[/tex]
[tex]A-p = prt[/tex]
[tex]\frac{A-p}{pt} = \frac{prt}{pt}[/tex]
[tex]r = \frac{A-p}{pt}[/tex]
∴ Option B is correct

Please help answer the following question
Answer:
D
Step-by-step explanation:
The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).
<2 + 40 + 40 = 180 Combine the left
<2 + 80 = 180 Subtract 80 from both sides
<2 = 180 - 80
<2 = 100 degrees.
That's not the answer. We have to solve for x
<2 = x + 106
100 = x + 106 Subtract 106 from both sides
100 - 106 = x
x = - 6

Gail has $5,500 that she wants to put in a new savings account. She is
considering two banks that are very similar. One difference she notices
are the interest rates:
• Neighborhood Bank - 0.65% interest, compounded weekly
Beautiful Day Bank - 0.65% interest, compounded daily
.
Based on interest, which bank would you suggest Gail pick if she plans to
have her money in the account for 15 years?
Answer: Neighborhood Bank - 0.65% interest, compounded weekly
Step-by-step explanation:
The bank she would suggest Gail pick if she plans to have her money in the account for 15 years is Neighborhood Bank - 0.65% interest, compounded weekly.
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
Given that Gail has $5,500 that she wants to put in a new savings account.
Neighborhood Bank - 0.65% interest, compounded weekly
Beautiful Day Bank - 0.65% interest, compounded daily
Thus, $5,500 x 0.65% = $35.75
$35.75 a day times 360 days = $12870
$12870 times 20 = $257,400.
$257,400 times 20 = $514800 (16.2mil)
Hence, The bank she would suggest Gail pick if she plans to have her money in the account for 15 years is Neighborhood Bank - 0.65% interest, compounded weekly.

Which equation represents the line that is perpendicular to y = $5 + 23 and passes through (-40,2012
- 15
y = - = - 30
= 5 + 52
= - 56
ОВ.
Ос. y =
OD.
Answer:
The question is written kinda bad, so i take the next two assumptions:
The original line is:
y = 5*x + 23
And we want to find a perpendicular line that passes through the point (-40, 2012)
Suppose that we have a linear equation:
y = a*x + b
A perpendicular line to this one, will have a slope equal to -(1/a)
Then a random perpendicular line to the one above, is:
y = -(1/a)*x + c
In this case, we start with the line:
y = 5*x + 23
Then the family of perpendicular lines to this one, will be like:
y = (-1/5)*x + c
Where c can be any real number.
Now, we also want this line to pass through (-40, 2012)
This means that when x = -40, the value of y must be 2012
We could replace these values in our equation above and solve it for c.
2012 = -(1/5)*(-40) + c
2012 = 40/5 + c
2012 = 8 + c
2012 - 8 = c = 2004
Then the equation is:
y = -(1/5)*x + 2004.
