Answer:
Step-by-step explanation:
∠ADC = 90°
∠ADB + ∠BDC = 90
20 + ∠BDC = 90
∠BDC = 90 - 20 = 70
∠BDC = 70°
16) ∠PSR = ∠PSQ +∠QSR
= 60 + 10
= 70
18) ∠PSR = 130
∠PSQ + ∠QSR = 130
90+ ∠QSR = 130
∠QSR = 130 - 90
∠QSR = 40
19)∠ADC = ∠ADB + ∠BDC
= 120 +20
= 140
20) ∠PSR = 125
Answer:
The answer is approx 75 months.
Step-by-step explanation:
We have P = 3000
r = 14%
Monthly payment = $60
We will use the formula :
![[(0.14/12) \times3000] / [1- (1+(0.14/12)^{-12n}]](https://tex.z-dn.net/?f=%5B%280.14%2F12%29%20%5Ctimes3000%5D%20%2F%20%5B1-%20%281%2B%280.14%2F12%29%5E%7B-12n%7D%5D)
Solving this we get n = approx 75 months. After 75 months few dollars will be left. And in the 76th month the balance will become negative.
For easy and better understanding, I have attached an excel sheet.
The answer is approx 75 months.
Twelve and nine thousandths
The ratio of flowers to bouquets is
64:8
With 80 flowers, the ratio would be
80:x
so...
64:8 divide each by 8 to get 8:1
multiply each by 10 to get
80:10
10 bouquets
3•2•7=42•2=84
12•10•7=840
84+840=924in^3
