Use I = PRT to solve.
(time is in years)
1 = $312.50
R = 25%
T = 0.25 years
Find P.
Please help :)) for 35 points !
Answer:
Step-by-step explanation:
I = PRT
PRT = I
P = I/RT
P = 312.50/(.25)(.25)
P = 312.5/.0625
P= $5000
Principal for the given interest, rate of interest and time period is $5000.
Given that, I = $312.50, R = 25% and T = 0.25 years.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.
Now, SI=(P × R × T)/100
312.50= (P × 25 × 0.25)/100
⇒ P × 25 × 0.25 = 31250
⇒ P = 31250/6.25
⇒ P = $5000
Therefore, principal for the given interest, rate of interest and time period is $5000.

A population of 30 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain 600 deer. The population would grow by 30 percent per year
Complete question :
A population of 30 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain 600 deer. The population would grow by 30 percent per year
how many after one year
how many after two years
Answer:
39 deers
51 deers
Step-by-step explanation:
The question can be expressed using the compounding rate formula:
A = P(1+r)^t
A = final population ; P = initial population ; rate, r = 30% = 0.3 ; t = time
After 1 year, t = 1
A = 30(1 + 0.3)^1
A = 30(1.3)^1
A = 39 deers
B.)
After 1 year, t = 2
A = 30(1 + 0.3)^2
A = 30(1.3)^2
A = 50.7
A = 51 deers approximately

Answer:
497 inches²
Step-by-step explanation:
Hi!
I have never done a problem like this in my life but I see exactly how it is meant to be solved. Lets try it out.
Let us first remind ourselves of the formulas we need for this.
Formula for a circle and the formula for a triangle.
Circle :
A = [tex]\pi[/tex] x r²
(or Area = pi x radius²) (Note that [tex]\pi[/tex] = 3.14)
Triangle :
A = b x h x 1/2
(or Area = base x height x 1/2)
Now lets see what the question wants from us and what we are given :
Gives us :
Diameter XY = 30 inches
YZ = 20 inches
XZ = 21 inches
And it wants the total area of the shaded regions to the nearest square inch. (Inches²)
Alright so first lets solve this triangle :
We need to do Base x Height x 1/2 :
Input your numbers given :
Base = 21in
Height = 20in
And lets multiply this out :
Base x Height x 1/2
21 x 20 x 1/2
21 x 20 gives us 420
Now we have :
420 x 1/2
Note that this is literally saying it wants half of 420. So we can actually just make it easier and do :
420/20
This gives us 210.
Great! Now we have the area of the triangle which is 210, this will be important later but for now lets move onto the circle.
Alright so we need radius to solve this but it really doesn't give us much about the circle.
But...
If you take a look at ∠YX you can see that it says 30in. This is actually the diameter of the circle and we can use this to find the radius of the circle.
The radius of a circle is 1/2 of the diameter.
And the diameter of a circle is 2 × the radius.
So in this case to find the radius we can actually take the 30inch diameter and divide it by 2 to find our radius.
30/2
=
15
Radius = 15inches!
Now lets look back to our wonderful circle formula.
A = [tex]\pi[/tex] x r²
or if we write it out :
Area = pi x radius²
So now lets plug in the radius we found and then solve to find the area of this circle.
Area = pi x 15²
(Don't forget the tiny 2 next to the 15!)
Now we can multiply this :
pi x 15²
=
706.858347058
Round to the nearest square inch :
707 inches²
(pi = [tex]\pi[/tex])
So now what we have is the area of both shapes. It is smooth sailing from this point on. Let us recap :
Triangle Area = 210 inches²
Circle Area = 707 inches²
Now we have to find the area of the shaded area which is really simple subtraction.
The shaded area is the circle but the triangle is overlapping this shaded area so all we have to do is subtract the triangles area from the circles area so all that will be left is the shaded area of the circle.
So we do :
Circles area - Triangles area = Our answer
707 - 210 = 497
There we go!
Our answer is 497 inches²
This took a minute I am sorry about that but I hope this helps!

One number is 6 less than 5 times the other number. Their sum is 60. Find the numbers.
Answer:
The numbers are 11 and 49.
Step-by-step explanation:
x = 5y - 6 This is just the first sentence written as an equation.
x + y = 60 This is just the second sentence written as an equation.
5y - 6 + y = 60 Substitute x for what you know it is equal to
6y - 6 = 60 Collect like terms
6y = 66 Add 6 to each side
y = 11 Divide each side by 6
x = 5 × 11 - 6 Substitute y for what you know it is
x = 55 - 6 Simplify by working out 5 × 11 = 55
x = 49 Subtract 6 from 55 to get 49

Step-by-step explanation:
2[tex]\sqrt{2x}[/tex] = a
Divide both sides by 2.
[tex]\sqrt{2x}[/tex] = [tex]\frac{a}{2}[/tex]
Square both sides.
2x = ([tex]\frac{a}{2}[/tex])²
= [tex]\frac{a}{2}[/tex] × [tex]\frac{a}{2}[/tex]
2x = [tex]\frac{a^{2}}{4}[/tex]

How many more people like to swim than hike?
Show how you added or subtracted to find the answer
The number of people who likes to swim than hike is given by the equation A = 2 people
What is an Equation?Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.
It demonstrates that the expressions on the left and right sides are connected in the same way.
An equation has components like as coefficients, variables, operators, constants, terms, expressions, and the equal to sign. The "=" sign and terms on both sides are required when generating an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number of people who likes to swim be s= 4 people
Let the number of people who likes to hike be h = 2 people
Let the number of people who likes to bike be b = 3 people
Now , the equation will be
The number of people who likes to swim than hike A = number of people who likes to swim - number of people who likes to hike
The number of people who likes to swim than hike A = s - h
The number of people who likes to swim than hike A = 4 - 2
The number of people who likes to swim than hike A = 2 people
Hence , the number of people who likes to swim than hike is A = 2 people

Step 1: Define Variables
Stuffed bears = b
Stuffed dogs = d
Step 2: Define Systems
$7b + $8d = $3800
b + d = 500
Step 3: Rewrite Systems
b + d = 500
[Equality Property] Multiply everything by -7: -7b - 7d = -3500Step 4: Redefine Systems
7b + 8d = 3800
-7b - 7d = -3500
Step 5: Solve for d
Elimination
Combine 2 equations: d = 300Step 6: Define Answer
d = 300 means that the students bought 300 stuffed dogs.
Answer:
D
Step-by-step explanation:
Remark
Let the stuffed bear = x
Let the stuffed dog = y
Equations
x + y = 500 (1)
7x + 8y = 3800 (2)
Solution
There are two ways you could do this. You can use substitution or you could use multiplying equation 1 by either 7 or 8 to get rid of the x or y.
Multiply (1) by 7
7x + 7y = 3500 (3) Write equation (2) below (3) and subtract
7x + 8y = 3800 Subtract
-y = - 300 Multiply by - 1
y = 300
Use the result for y to get x using equation 1
x + y = 500
x + 300 = 500 Subtract 300
x = 500 - 300
x = 200
Stuffed bears = 200
Stuffed dogs = 300
