Answer:
30
Step-by-step explanation:
Ratios always remain proportionate. In this case, the simplified ratio has 1 red car. The question tells us that there are 6 cars. 6 is 6 times bigger than 1; thus showing that the ratio has increased by a factor of 6. If one side of the ratio increases by a factor of 6, then the other side must also increase by a factor of 6. Since 5*6=30, there must be 30 employees that own a black car.
Answer:
Using the formula:
where
A is the total amount
P is the principal
I is the Simple Interest
As per the statement:
Principal(P) = 5300 rupees.
rate of interest(r) = 6.5% = 0.065
Total amount(A) = 6678 rupees.
Then using above formula we have;
Subtract 5300 both sides we get;
or
We have to find the time period.
Using formula of Simple interest:
where r is the rate of interest (in decimal)
here, r = 6.5% = 0.065
Substitute the given values top find t:
⇒
Divide both sides by 344.5 we have;
Therefore, the time period t in years is 4 years
Answer:
B. 195.5 kg
Step-by-step explanation:
Given
Weight in pounds = 430 pounds
1 kilogram = 2.2 pounds
Required
The weight in kilogram
Let x represents the weight of the humpback's whale's heart in kilogram
Such that;
By Cross multiplication
Divide both sides by 2.2lb
Approximate
Hence, the weight of the heart is 195.5kg
42
Step-by-step explanation:
