Answer:
10.50
Step-by-step explanation:
16.50-6
Year 1990, dolphins were 243,000
2.3% of 24300
= ( 2.3 / 100 ) * 243000
= ( 0.023 ) * 243000
= 5589
So every year, the population of dolphins decrease by 5589.
Now from 1990 to 2030 will be
= 2030 - 1990
= 40 years
Therefore, for a year = 5589 decrease
For forty years, it will be
= 40 * (5589)
= 223560 dolphins will be lost after forty years
The remaining ones
= 243000 - 223560
= 19440 dolphins will be left
Answer:
105 divided by 7
Step-by-step explanation:
to find out you need to divide

Answer:
Point {eq} \ B displaystyle (x, y) {/ eq} divide la AC de una manera tal que {eq} \ displaystyle AB = \ frac {2} {3} AC {/ eq}B ( x , y )si(X,y)A B = 2 3A CUNAsi=23UNAC
Significa {eq} \ displaystyle AB: BC = 2: 1 = m: n {/ eq} A B : B C = 2 : 1 = m : nUNAsi:siC=2:1=metro:norte
Y las coordenadas del punto {eq} \ displaystyle A (1, -5) ~ \ text {y} ~ C (-5,4) {/ eq} A ( 1 , - 5 ) y C ( - 5 , 4 ) UNA(1,-5 5) y C(-5 5,4 4)
Entonces las coordenadas del punto B son:
B ( x = m x 2 + n x 1 m + n, y = m y 2 + n y 1 m + n )si(X=metroX2+norteX1metro+norte, y=metroy2+nortey1metro+norte)
Sustituir los valores,
B ( x = 2 × ( - 5 ) + 1 × 1 2 + 1, y = 2 × 4 + 1 × ( - 5 ) 2 + 1
