Q + n = 91
q +n -n =91-n
q= 91-n
.25q +.05n = $14.55
.25(91-n)+.05n = $14.55
22.75-.25n+ .05n= $14.55
22.75 -.20n =14.55
22.75-22.75-.20n=14.55-22.75
-.20n=-8.2
-.20n/-.20n= -8.2/-.20n
n= 41
q + 41 = 91
q +41 -41 = 91-41
q = 50
CHECK
.25(50) + 0.05(41) = $14.55
12.50 + 2.05 = $14.55
$14.55 = $14.55
Answer:
$6,824.03 is the amount the family will spend on vacations in 5 years
Step-by-step explanation:
The formula A = P(1 + r)^n is appropriate in this problem, with the understanding that A represents the amount the family will spend on vacations in n years and P is the current spending amount. Then:
A = ($7,845)(1 - 0.0275)^5, where we use -0.0275 to indicate that the amount DECREASES by 2.75% annually. Simplifying this formula, we get:
A = ($7,845)(0.9725)^5, whose value to the nearest cent comes out to:
A = $6,824.03 is the amount the family will spend on vacations in 5 years.
Use formula y = k x and find value of k using any of the coordinates
Answer:
Name: Circle A
Chords: Chord DP, Chord HC
Tangent: EFG
Step-by-step explanation:
Name a circle by the center, in this case it's A.
Chord: A chord is a line only in the circle, not outside of it, and its endpoints are right on the circle.
Tangent of a circle: "Tangent" means touching, and this is a line, in terms of a circle, that touches the circle but is not INSIDE of the circle.
