Given:
Neelam's daily income is ₹800.
Her daily savings amount is ₹100.
To find:
The ratio of her SAVINGS to her EXPENDITURE.
Solution:
We have,
Income = ₹800
Saving = ₹100
Expenditure = Income - Saving
= ₹800 - ₹100
= ₹700
We need to find the ratio of her SAVINGS to her EXPENDITURE.
[tex]Ratio=\dfrac{Savings}{Expenditure}[/tex]
[tex]Ratio=\dfrac{100}{700}[/tex]
[tex]Ratio=\dfrac{1}{7}[/tex]
[tex]Ratio=1:7[/tex]
Therefore, the correct option is b.

Tanya is n years old today. How old will she be in 5 years
Answer:
n+5
Step-by-step explanation:
Answer:
n + 5 or 5 + n
Step-by-step explanation:
add 5 to n, tanya's current age, to find how old she'll be in 5 years.
since the variable n is not defined, the answer cannot be simplified further than n + 5.
if n had been defined, you would be able to figure out her exact age after 5 years, which would be the fully simplified answer. for example, if n were to equal 10, then tanya would currently be 10 years old. by plugging in 10 for n in n + 5, you would figure out that in 5 years (aka 10 + 5) tanya would be 15.
i hope this helped! have a great day <3
pls help with this problem if u do thx <3
======================================
Work Shown:
c = price of coat before discount
0.33c = discount = amount you save
c - 0.33c = original price minus discount = final price
c - 0.33c = 1c - 0.33c = (1-0.33)c = 0.67c = final price
In short, c - 0.33c = 0.67c
They are two ways of expressing the same thing.
You can think of it like saying 100% - 33% = 67%
If you save 33%, then you still have to pay the remaining 67% of the original cost.
-------------
Example:
Let's say the coat is $100 before the discount
c = 100
0.33*c = 0.33*100 = 33 dollars is how much you save
c - 0.33c = 100 - 33 = 67 dollars is the final price
0.67c = 0.67*100 = 67 matches with the previous figure above

Find the incorrect step in each solution and explain whit it is incorrect.
Answer:
Step-by-step explanation:
Mai:
She subtracted 5x instead of distributing. This is incorrect, because since it is in ( ), it has to be multiplied by 3.
Correct: 3(5x + 9) = 15x + 27
12x + 3 = 15x + 27
Noah:
Added 15x instead of subtracting. This is incorrect, because to combine like terms on each side you would add a negative number and subtract a positive number.
Correct: 12x + 3 = 15x + 27
12x - 15x = 27 - 3
-3x = 24
x = 24 / -3
x = -8

Think About the Process Van purchased a DVD player on sale. The original
selling price was $175.90. The sale price was $149.62. What is the first step in
finding the percent markdown? Find the percent markdown.
much appreciated if helped :(
Answer:
14.940306992% or 15%
Step-by-step explanation:
To solve for percent or price markdown, you first have to find the difference between the original selling price and the sale price.
$ 175.90 - $ 149.62 = $26.28
Then, find the percentage that $26.28 is of the original selling price. You are decreasing the original by this much to get to the sale price.
$26.28 / $175.90
= 0.14940306992
Finally, multiply by 100 and round up to reach a percentage.
15%

Step-by-step explanation:
Kiera and Hannah have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Kiera earns a base wage of $6 per hour, as well as $1 for every subscription that she sells. Hannah gets $2 per subscription sold, in addition to a base wage of $4 per hour. If they each sell a certain number of subscriptions in an hour, they will end up earning the same amount. How many subscriptions would that be? Write a system of equations, graph them, and type the solution
Answer:
Hannah sold 4
Kiera sold 6
Total Subscriptions = 10
Step-by-step explanation:
K = number of Kiera subscriptions
H = number of Hannah subscriptions
T = hours
6+K = 4+2H
K = 2H-2
K+H = 10
K= 10-H
substitute for K
2H-2 = 10-H
simplify
3H = 12
H = 4
K = 6

F(x)=4x^2+4x-15 Write the function D in intercept form. Use this form to list the zeros of the function.
Answer:
Zeros are x = 1.5, -2.5
Step-by-step explanation:
Given function is,
F(x) = 4x² + 4x - 15
= 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]
F(x) = 4(x² + 2.5x - 1.5x - 3.75)
= 4[x(x + 2.5) - 1.5(x + 2.5)]
= 4(x - 1.5)(x + 2.5)
For 'x' intercepts,
f(x) = 0
4(x - 1.5)(x + 2.5) = 0
x = 1.5, -2.5
Therefore, zeros of the given function are x = 1.5, -2.5.

ABCD ~ FECG
Y=
Please helpp
=========================================================
Explanation:
Notice how EC = 5 doubles to BC = 5+5 = 10
So the larger quadrilateral (ABCD) has side lengths that are exactly twice as long compared to the smaller quadrilateral's sides. We can say the scale factor is 2.
This must mean that side FG = 4 doubles to 4*2 = 8, which is the length of side AD. So that's how we get y = 8.
-----------------------------------
Extra info:
x = 12 because side EF = 6 doubles to this value. w = 120 because the corresponding angles of ABCD pair up with FECG, so we see that angle D = angle G = 120.z = 80 because we solve F+E+C+G = 360 to find that F = 80, which leads to angle A = 80 as well.Length of AD, y = 8
What are similar quadrilateral?Two quadrilaterals are similar if their corresponding angles are equal and also their corresponding sides must be proportional.
Given,
EC = 5
FG = 4
BE = 5
AD = y
ABCD ~ FECG,
then ratio of the corresponding sides will be equal.
BC/AD = EC/FG
(BE + EC)/AD = EC/FG
(5 + 5)/y = 5/4
10/y = 5/4
5y = 40
y = 40/5
y = 8.
Hence, 8 is value of y that is length of AD.
