The statement is true.
Explanation.
When two triangles are similar, the ratios of corresponding sides of the two triangles will be the same.
For example,
If ΔABC ~ ΔDEF, then
AB/DE = BC/EF = AC/DF.
286 = 100 %
199.5 = x
In order to find x we need to cross multiply 286*x=199.5*100
286x=19950 / 286
x=69.8 (%)
3/4 of 52 is 39 + 1 is 40.
So the answer is 40 weeks.
Answer:
All of these terms are dollar amounts.
Step-by-step explanation:
Here, x + y = 10 (where these numerals represent counts)
(1/2)x + (1/4)y = 4 (where (1/2), (1/4) and 4 are dollar amounts)
Let's eliminate y. To accomplish this, mult. the 2nd eq'n by-4, obtaining
-2x - y = -16, and then combining this with the 1st equation, as follows:
-2x - y = -16
x + y = 10
-------------------
-x = -6, or x = 6. This represents the number of pens purchased by Terrance.
Subbing 6 for x in the first equation, we get y = 4. This represents the number of pencils he bought.
($0.50)x + ($0.25)y = $4.00 (dollar amounts)
