a)
V=p+prt
now we solve for P
V=P (1+rt)
Divide both sides by (1+rt)
P=V÷(1+rt)...answer
b)
P=V÷(1+rt)
P=3,000÷(1+0.06×5)
P=2,307.69
Step-by-step explanation:
let an amount be a
increase an amount by 10% and then by 30%
= a*1.1 *1.3 = a*1.43
Answer:







Step-by-step explanation:
Thanks!!!!
(AAA) Corresponding angles are congruent.
Therefore, the sides of the triangles are proportional:
cross multiply
use distributive property
subtract 100 from both sides
divide both sides by 100

(SAS)
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
Therefore we have the equation:

The perimeter of △PQR:

Substitute the value of y to the expression:

The first decimal point is tenth. 4.88
when rounding, we just look at the number right after the number you want to round to. it's 8 right? since 8 is closer to 10 than 0,
we round it to 4.9
(4.8 + 0.10)
