Answer: Chiara's monthly payment is $194.7
Step-by-step explanation:
The cost of the new natural gas barbecue for $2,100. She made a down payment 30% off the purchase price. This means that the amount of down payment made is
30/100 × 2100 = 0.3 × 2100 = $630
Amount left to pay would be
2100 - 630 = $1470
The formula for determining monthly loan payment is
A = P(r(1 + r)^n)/((1 + r)^n - 1)
There would be 9 monthly payments, so
n = 9
r = 0.055/12 = 0.0046
P = 1470
A = 1470(0.0046(1 + 0.0046)^9)/((1 + 0.0046)^9 - 1)
A = (1470 × 0.0049)/0.037
A = 7.203/0.037
A = 194.67
Answer:
34; 34 inches is not long enough
Step-by-step explanation:
A doormat is the shape of a rectangle and its area uses A=l*w. If the area is 714 and its length is 21, then 714 = 21*w. Solve for w.
714=21w
714/21= 21w/21
34 = w
Answer:
15.5 units
Step-by-step explanation:
If a plane flies from city a to city b, to determine how long in units the airplane's path on the map as the airplane flies along a straight line from city a located at (20, 14) to city b located at (5, 10), we will use the formula for calculating the distance between two points as shown.
D = √(x2-x1)²+(y2-y1)²
Given the location of city 'a' at a coordinate (20, 14) and city b at (5, 10)
x1 = 20, y1 = 14, x2 = 5 and y2 = 10
Distance between the two cities will be expressed as D = √(5-20)²+(10-14)²
D = √(-15)²+(-4)²
D = √225+16
D = √241
D ≈ 15.5 units
Hence, the airplane path on the map as it move from city a to b is approximately 15.5 units.
