10X^5 + 5x^3 - 14x^2 - 7
= 5x^3(2x^2 + 1) - 7(2x^2 + 1)
= (5x^3 - 7)(2x^2 + 1) answer
Answer:
30 mi/ 24 mi (6 mi slower)
Step-by-step explanation:
distance = rate x time
distance = 20 mph * X hr = 20 X miles
return trip:
distance = 16 mph * X hr + 6 miles = 16X + 6
They are the same:
20X = 16X + 6
4X = 6
X = 6/4 = 3/2
20 mph * 3/2 hr = 30 miles.
On the return trip: 16 mph * 3/2 hr = 24 miles, which is 6 miles short of 30 mi.
The distance is 30 miles.
The bird flies all 30 miles in 3/2 hr = 1 and 1/2 hour = 1 hour 30 minutes.
On the return trip, the bird flies 24 miles in 1.5 hours, which is 6 miles short.
Answers: choice C and choice D
The ratio can be thought of as a fraction. Let's say that a country is $100 in debt and has a GDP of $50. These are simplified smaller numbers of course just for the purpose of an example. The debt-to-GDP ratio would be debt/GDP = 100/50 = 2 meaning that for each dollar of GDP, there are 2 dollars of debt. Put another way, the amount of debt is double that of GDP.
Let's say that debt goes up but GDP says the same. Let's make debt jump up $50 to get to $150 in debt. The ratio is now 150/50 = 3. So the ratio has gone up (from its previous value of 2). This example shows how choice D is true.
Now let's consider debt staying the same but GDP going down. If we drop the GDP from 50 to 25, then the ratio is: 100/25 = 4 and we see the ratio has gone up (from the previous value of 2). This shows how choice C is true.
Note: If scenario C and scenario D happen at the same time, then the ratio would also go up.
Answer:
Parte dividida o separada de un todo considerada por separado.
Step-by-step explanation:
Answer:
for first car
c = 250 + 0.02*$115,075 = 2551.5
for second car
c= 250 + 0.02*$21,640 = 682.8
total commission= 2551.5 +682.8 = 3234.3
