Answer:
I. 1,000 dollars
II. 1,061.84 dollars
III. 1,127.50 dollars
Step-by-step explanation:
Formula for continuous compound interest:
[tex]A = Pe^{rt}[/tex]
Plug in the values for one year:
A = 1000(2.71828)^(0.06)(1)
A = 1,061.84 dollars
Plug in the values for two years:
A = 1000(2.71828)^(0.06)(2)
A = 1,127.50 dollars

The Volume () of gas vanes inversely to the pressure (P). The volume of gas is 200 cm ^ 3 under pressure of 32 kg/cm^ 2 What will be the amount of pressure if the volume is 256, 000 cm ^ 3 ? Kg/ cm²
Answer:
0.025 Kg/ cm²
Step-by-step explanation:
if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable
the equation that represents inverse proportion :
[tex]y = \frac{b}{x}[/tex]
where b = constant of proportionality
to determine the answer in this question :
1. determine constant of proportionality
200 = k / 32
k = 6400
2. Determine the amount of pressure using the constant of proportionality
256, 000 = 6400 / pressure
pressure = 6400 / 256, 000 = 0.025

Find the value of x and show all steps please
Answer:
x = 88
Step-by-step explanation:
Opposite angles in a quadrilateral inscribed in a circle are supplementary
Supplementary meaning that the sum of the two angle measures is 180
The opposite angle of "x" is ∠B which has a measure of 92°
Thus, 92 + x = 180
180 - 92 = 88
Hence, x = 88

Manuel wants to build a model of Captain America's famous shield out of cardboard. The outer ring of the shield is colored red. The next ring is white. The third ring is also red. The center is blue with a white star. The radius of the whole shield is 14 inches. However, Manuel just wants to know the area of the space he needs to paint red. Use 3.14 for Pi. Round to the nearest hundredth
Answer:
615.44 in²
Step-by-step explanation:
The shape of Captain America's shield = Circular
The area of a circle = πr²
The radius of the whole shield = 14 inches.
The first ring = Red ring
Hence, the area of the red ring =
π = 3.14
3.14 × 14²
= 615.44 in²
The area of the space he needs to paint red is 615.44 in²

The sum of a man and his wife is 81 years. The ratio of their ages is 5:4 Find the age of the younger person
Answer:
Age of a younger person (wife) is [tex]36[/tex] years.
Step-by-step explanation:
The sum of a man and his wife is [tex]81[/tex] years.
Also, ratio of their ages is [tex]5:4[/tex]
Let ages of a man and his wife be [tex]5x[/tex] and [tex]4x[/tex].
Therefore,
[tex]5x+4x=81\\9x=81\\x=9[/tex]
Age of man [tex]=5x=5(9)=45[/tex] years
Age of his wife [tex]=4x=4(9)=36[/tex] years.
So,
age of a younger person (wife) is [tex]36[/tex] years.

The answer is [tex]a^{2} -(2*4)[/tex]
Step-by-step explanation:Definition of square and rectangle
A plane figure having four equal sides and four right (90°) angles in geometry is called a square.
A rectangle is a two-dimensional shape with four sides, four corners, and four right angles. A rectangle's opposite sides are the same length, with one pair being longer than the other.
The area of given square= a²
The area of rectangle= 2*4
Hence the area of shaded region= [tex]a^{2} -(2*4)[/tex]

Answer:
∠1 = 52
∠2 = 128
∠4 = 128
Step-by-step explanation:
∠3 and ∠1 are vertical angles
As we now vertical angles are congruent
So if ∠3 = 52°, then ∠1 also equals 52°
∠3 and ∠4 are supplementary angles
supplementary angles add up to equal 180
Thus, ∠3 + ∠4 = 180
If ∠3 = 52°
Then 52 + ∠4 = 180
180 - 52 = 128
Hence, ∠4 = 128
∠4 and ∠2 are vertical angles
Like stated previously vertical angles are congruent
So if ∠4 = 128 then ∠2 also equals 128
there are 14 red marbles and 19 blue marbles in a bag you randomly choose one of the marbles what is the probability of choosing a red marble write your answer as a fraction in simplest form
Answer:
4/23
Step-by-step explanation:
Probability of choosing a red marble = # of red marbles / total # of marbles
We are told that there are 4 red marbles and 19 blue marbles
So the # of red marbles = 4
And the total # of marbles = 4 + 19
4 + 19 = 23
So there are a total of 23 marbles
Recall that probability of choosing a red marble is equal to # of red marbles / total # of marbles
Hence, the probability of choosing a red marble is 4/23
Note: 4/23 is already in it's simplest form so no simplifying has to be done.
Answer:
14/33
Step-by-step explanation:
There are 14 red marbles and 19 blue marbles, meaning that there are 33 marbles in all:
14 + 19 = 33
You are randomly choosing a red marble out of the total amount of marbles. 14/33
Note that you cannot simplify the fraction anymore, and so 14/33 is your answer.

Jill counted 105 people in front of her in line for a park train ride. The train holds 12 people on each trip. How many trips will the train take before it is jill turn?
Answer:
105 divide 12 = 8.75 so therefore, there will be 8 trips before it is jill's turn
Answer:
8 trips
Step-by-step explanation:
Divide 105 by 12 to find how many trips the train will take:
105/12
= 8.75
This means that the train will take 8 trips before it is Jill's turn. Since you can only have a whole number of trips, we have to round 8.75 down to 8.
So, the train will take 8 trips before it is Jill's turn.
