A person distributed his property of Rs 1000000 among his three sons and one daughter. Each son got 27% of the property. How much did the daughter get?
[tex] \mathscr{HELP!!}[/tex]
Answers
Have a good day :)
Answer:
Rs 190000
Step-by-step explanation:
Total property = Rs 1000000
For 1 son= 27% of the property
For 3 sons=27%×3= 81%
For daughter=100%-81%=19%
Now,
For daughter
19% of Rs 1000000
19/100 × Rs 100000
Rs 190000
Hence the daughter will get Rs 190000
Find the cost of purchasing 30 roses. Show how you know.
Answers
Answer:
90 dollars
Step-by-step explanation:
so first you need to solve for the rate of change or slope with the equation
y 2 - y1 / x2 - x1
here i think the independent variable is number of roses since the dollars rely on the number of roses (sorry for my explanation its kinda bad)
so since number of roses is independent we know that it is x and that the price in dollars is y
anyways we have to substitute two values into the equation
y 2 - y1 / x2 - x1
(3, 9) (6, 18)
18 - 9 / 6 - 3
9 / 3
3
knowing that the rate of change is 3, to find the price for 30 roses all we have to do is:
let p be price
p = 3x
p = 3(30)
p = 90 dollars
the picture shows a transparent piece of paper with a design drawn on it. The paper is then folded twice, as shown. what will be seen on the folded paper?

Folding the paper is an illustration of rotation
Two right triangles and one square would be seen on the diagram, when folded
How to determine the output of folding the paperFrom the figure, we have the following highlights
The paper is a squareThe paper is transparentThe designs on the paper are on either sidesThis means that when the paper is folded as shown, the designs would fall on each other, and the shapes would fit in perfectly.

Larry wanted to buy a notebook computer. He had $700 to spend. The salesman tried to
sell Larry a computer that cost $850, but Larry said that was too expensive. The
salesperson said he could give Larry 25% off of the price if he used a coupon. Sales ta
is 9%. Could Larry afford the computer? How much would it cost?
Answers
Answer:
yes, $694.88
Step-by-step explanation:
You have to find the cost after applying the coupon and sales tax. First remove 25% from the price by finding 75% of the price. 850*.75=$637.5 after applying the coupon. Then you would have to increase it by 9% to account of sales tax, so multiply by 1.09. 637.5*1.09= $694.88 after sales tax. This means that Larry can very narrowly afford the computer.
A line passes through the points (20, 15) and (19, 14) What is its equation in slope-intercept form?
Answers
Answer: y = x - 5
Step-by-step explanation:
Slope intercept form is y = mx + b
to find the slope: y2-y1/x2-x1: 15-14/20-19 = 1/1 = 1
so we can write it as y = x + b, (since the slope is 1).
To find b, plug in either point given to the formula:
15 = 20 + b
b = 15 - 20
b = -5
so the completed equation is y = x - 5
Answer:
y = x-5
Step-by-step explanation:
The form of slope intercept is y=mx+b]
To solve :
First you need to find the slope
To find the slope, you the slope equation, which is y2-y1/x2-x1
Since first you put y2-y1 at the top, it would be 14-15 and then 19-20 at the bottom since x2-x1 is put at the bottom.
Your slope equation should be : m=14-15/19-20, which should give you m=-1/-1 with m being 1.
Then you plug in the value in the slope intercept equation
To help us find the y intercepts, lets choose one our points. In this case, we will be using (20,15) since it is the first point.
Slope intercept form is y=mx+b.
we do 15= 1 x 20 +b
15=20+b, gives you b=-5
How you got b=-5:
1)Put the equation into this by switching sides :
1 (20)+b=15
2) Get rid of the parenthases :
1 x 20 + b=15
3) multiply :
1 x 20=20, so
20+b=15
4) On both sides, subtract 20
so it would be
20+b-20=15-20, which gives you b=-5

So your question 10. becomes:
(-19 + 20 + 34) / -6, which is more pleasant to the eye.
Further simplifying gives you 35 / -6 which you should write as -35/6.
