19,3/4 = 79/4
15,3/4 = 63/4
Perimeter = 79/4+79/4+63/4+63/4 = 284/4 = 71feet
22,1/2 = 45/2 X 4 = 90
90-71= 19 feet
Let me know if you need more of an explanation, but the answer in 19 feet (option 4)
Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
y = P(1 + r/n)^nt
Where
y = the value of the investment at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount invested
From the information given,
P = $4700
r = 4.75% = 4.75/100 = 0.0475
n = 1 because it was compounded once in a year.
Therefore, the exponential function showing the relationship between y and t is
y = 4700(1 + 0.0475/1)^1 × t
y = 4700(1.0475)^t
The answer is 121
explanation : 11 x 11 = 121
Step-by-step explanation:
I don't see question 1 and 2.
but it did be way for you : the distance from the verge of a circle to a point on the circle is always the radius.
that is the whole concept of a circle : it is the line (or curve) of all points that have the same, constant distance r from a single point.
Try this solution/explanation:
<u>way 1</u>:
rule: for an equation where no roots P+Q=0. It means, Px-Qx=0, ⇔ x(P-Q)=0, ⇔ P=Q.
for answer 'D' P=Q=15.
<u>way 2</u>:
rule: if an equation of the line has a form y=kx+b, then y₁||y₂ if k₁=k₂. It means, for y₁=Px-45 || y₂=Qx+75, then P=Q. P=Q, if 'D' answer.
Answer: D
