Answer:

nevada will earn $300 interest and the total balance after 18 months is $4,300.

Step-by-Step Explanation:

we use this following formula to find how much interest nevada has :

simple interest = principal * interest rate * time

since the amount of time is in months, we have to convert it into years. we use interest in years ONLY.

1 year = 12 months

1.5 years = 18 months

now that we have the correct values to use this formula in, we now substitute the numbers in.

simple interest = principal * interest rate * time

simple interest = $4,000 * 0.05 * 1.5

here, we converted the percentage rate into a decimal because obviously, you cannot directly multiply percentages by money or normal numbers.

simple interest = principal * interest rate * time

simple interest = $4,000 * 0.05 * 1.5

simple interest = $200 * 1.5 (we multiplied the first two values first so it's easier to get the final answer)

simple interest = $300

we now have to find the total balance on nevada's account after 18 months by using the following formula :

total amount = principal + simple interest

since we know the amount of principal and interest already, all we have to do is substitute the numbers in.

total amount = principal + simple interest

total amount = $4,000 + $300

total amount = $4,300

therefore, nevada's total balance on her account after 18 months is $4,300.

Answer:

∠ 1 = 123°

Step-by-step explanation:

One way

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ 1 is an external angle of the triangle, thus

∠ 1 = 90° + 33° = 123°

Second way

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 for third angle in Δ

third angle = 180° - (90 + 33)° = 180° - 123° = 57°

The third angle and ∠ 1 form a straight angle and are supplementary, thus

∠ 1 = 180° - 57° = 123°

The number of kilograms, y, of original oxygen that remain in the body after t hours can be modeled by the equation y = 0.32(0.7
Artist 52 [7]

Answer:

24%

Step-by-step explanation:

The number of kilograms, y, of original oxygen that remain in the body after t hours can be modeled by the equation y = 0.32(0.76)^t . What is the rate of decrease of original oxygen?

The formula for Exponential Decrease is given as:

y = a(1 - r)^t

Where

y = Amount after time t

a = Original amount

r = Rate of decrease

t = Time

Comparing both Equations

y = 0.32(0.76)^t = y = a(1 - r)^t

We know that

0.76 = 1 - r

Solving for r

Collect like terms

r = 1 - 0.76

r = 0.24

Converting to Percentage

= 0.24 × 100

= 24%

Therefore, the rate of decrease of original oxygen is 24%

Butoxors [25]

Answer:

55 days or about 7 weeks

Step-by-step explanation:

9(7)= 63              because there are 7 days in one week

1(7)=7

7+6=<u><em>13</em></u>

68-13=55
