Answer:
In B) y = x/7 , the constant of proportionality is 7.
Step-by-step explanation:
Two quantities X and Y are said to be in proportion if and only if
X = kY or, 
,
where k = Proportionality Constant.
Here, 7 is the constant of proportionality. Then,
A . y = 14x
here, 
≠ 7
B . y = x/7
here, 
= constant of proportionality .
C. y = x
here, 
≠ 7
Answer:
Length = 80 m and breadth = 60 m If one moves along the two adjacent sides, one covers 80+60 = 140 m. Diagonal of the rectangle = √ ( length^2 + breadth^2) ...
Answer:
r≈4.75
Step-by-step explanation:
Answer:
A. $1500.00
Step-by-step explanation:
Assuming this is a simple interest savings account.
<u>Simple interest formula</u>
I = Prt
where:
- I = total interest
- P = principal amount
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- I = $225
- r = 3% = 0.03
- t = 5 years
Substitute the given values into the formula and solve for P:
⇒ I = Prt
⇒ 225 = P(0.03 ×5)
⇒ 225 = P(0.15)
⇒ P = 225 ÷ 0.15
⇒ P = 1500
Therefore, Timothy started the account with $1500.00.
