Answer:
Option no C
Step-by-step explanation:
Given:
Price of crackers $ 9 for 3 boxes
Price of Granola Bars $6 for 3 boxes
Total bought $ 20 worth of snacks
To find the equation
Solution:
Price of cracker $ 9 for 3 boxes
price of one box of a cracker = $ 9 / 3
=$ 3 per box
Price of granola bars $ 6 for 3 boxes
price of one box of a granola bars = $ 6 / 3
=$ 2 per box
Let total crackers bought are x
price of x crackers will be 3x
Let granola bars bought are y
price of y granola bars will be 2y
as total price is 20
so price of x crackes + y granolas = 20
which will be
3x + 2y = 20
which will be option no C

Answer: ASA congruency postulate
Step-by-step explanation:
Given: Parallelogram ABCD
To prove: ΔABD ≅ ΔBCD
Construction: Draw auxiliary line BD [see in the attachment]
Proof :- In ΔABD and ΔBCD
∠ADB=∠DBC [if lines are parallel, then its alternate interior angles are equal]
BD=BD [common]
∠ABD=∠BDC [if lines are parallel, then its alternate interior angles are equal]
⇒ΔABD ≅ ΔBCD [ASA congruency postulate]
⇒AD=BC and AB=CD [CPCTC]
- <em>ASA postulate tells if two angles and the included side of one triangle are equal to the corresponding parts of another triangle, then the triangles are congruent.</em>
Answer:
726
Step-by-step explanation:
The simple interest formula is as follows
AV=PV(1+it)
At time four this means that we have
AV=600(1+.042*5)
600*1.21= 726
Answer: a) yNA/100
b) NA(y-x)/100
c) (NA)/B
Step-by-step explanation:
a) The total amount of dollars owned by the shares' owner = N number of shares × A dollars per share = NA dollars
This total is then transferred to buy B shares which then appreciates by y%.
The amount of increase in portfolio from January to June = y% of total dollars invested = y% of NA dollars = yNA/100
b) If the shares were left with A, the increase in portfolio from January to June would be x% and = x% of the total Dollar amount = x% of NA dollars = xNA/100
How much more money made in that time would be the difference in interest, between taking the dollars to invest in share B or keeping the dollars on investment A
That is, (yNA/100) - (xNA/100) = NA(y-x)/100
c) Total dollars available after sale of the A stock = NA
Number of B stock this dollar can buy = Total dollars available/amount of B stock per share
That is, (NA)/B
