Hank decided to invest money into a retirement fund. If the average investment return is 12% and Hank invests the yearly maximum of $6,000 how much interest will that initial investment be worth in 20 years?
Answer:
$14400
Step-by-step explanation:
Using the formula for calculating the simple interest expressed as;
SI = Principal * Rate * Time/100
Given
Principal = $6000
Rate = 12%
Time = 20 years
Substitute into the formula;
SI = 6000 * 12 * 20/100
SI = 60*12*20
SI = 14,400
hence the interest worth after 20years will be $14400

The ratio of ounces of blueberries to ounces of yogurt is 2 to 5.How many ounces of yogurt would be needed for a smoothie with 10 ounces of blueberries?
Answer: 25 ounces of yogurt
Step-by-step explanation:
Blueberries to Yogurt
2 to 5
10 to ?
The original ratio is 2 ounces of blueberries and its now 10 ounces. We got ten ounces by multiplying 2 by 5. To get the ounces of yogurt, you have to also multiply by 5.
5 x 5 = 25
So the ratio of blueberries to yogurt is now, 10 to 25.

what is 1 3/4 + 1/6 + ? = 7 1/2
Answer:
x = 5 7/12
Step-by-step explanation:
let x = ?
7/4 + 1/6 + x = 15/2
multiply the equation by 12 to eliminate fractions
12([tex]\frac{7}{4}[/tex]) + 12([tex]\frac{1}{6}[/tex]) +12x = 12([tex]\frac{15}{2}[/tex])
21 + 2 + 12x = 90
23 + 12x = 90
12x = 90 - 23
12x = 67
x = 67/12 = 5 7/12
A ball is thrown into the air from the top of a building. The height, h(t), of the ball above the ground t seconds after it is thrown can be modeled by h(t)= -16t^2+64t+80 How many seconds after being thrown will the ball hit the ground?
Answer: Also can i have brainliest?
The ball will hit the ground 5 seconds after being thrown.
Step-by-step explanation:
The correct function is: h(t)= -16t^2+64t+80
You can rewrite the Quadratic function given in the exercise with making h(t)=0. Then this is:
0= -16t^2+64t+80
Now you can simplify the equation dividing both sides by -16. So you get:
0= t^2-4t-5
To find the solution of the Quadratic equation, you can factor it. In order to do this, it is necessary to find two numbers whose sum is -4 and whose product is -5. These number would be -5 and 1.
Therefore, you get this result:
0= (t-5) (t+1)
t1=5
t2=-1
Since the time cannot be negative, you can conclude that the ball will hit the ground 5 seconds after being thrown.

A Store recudes the price of a jacket by 40%. The sale price of the jacket is $30.
A. What percent of the original price is the sale's price
B. What was the original price of the jacket.
Answer:
A. 60%
B. The original price is $50
Step-by-step explanation:
A. 60%
Sales Price = 100 - 40 = 60%
The sales price is $30.00
Therefore 60% is equal to $30.00
60% = $30
1% = 30 ÷ 60 = $0.50
100% = 5 x 100 = $50
B. The original price is $50
Percentage of the original price = 30/50 x 100 = 60%

given f(x)=2x-10 determine the value if f(x)=8
Answer:
f(x)=2x-10 ______(given)
f(x)=8 _______(given)
Therefore, according to the above problem
2x-10=8
2x=10+8
2x=18
x=18/2
x=9
9 is the right answer.The value of the input of a function given the output is found by reversing
the operations of the function.
When f(x) = 8, x is 9.
Reasons:
The given function is; f(x) = 2·x - 10
Required:
The value of x if f(x) = 8
Solution:
When f(x) = 8, we have;
f(x) = 2·x - 10 = 8
Which gives;
2·x - 10 + 10 = 8 + 10 = 18
2·x + 0 = 18
[tex]x = \dfrac{18}{2} = 9[/tex]
x = 9
When f(x) = 8, x = 9

The ratio of boys to girls is 5:1 if there are 60 more boys than girls workout how many people there are in total
Answer: 80
Step-by-step explanation:
Let the number of girls be x
Therefore, the number of boys will be: = x + 60
The ratio of boys to girls is 5:1. Using this and equating to the number of bits and girls will be:
5/1 = x + 60/ x
Cross multiply
5x = x + 60
5x - x = 60
4x = 60
x = 60/4
x = 15
Number of girls = 15
Therefore boys will be: = x + 60 = 15 + 60 = 75.
Total number of people = 15 + 75 = 80

A campsite in the shape of a rectangle FGHI has sides (3x + 6) m and (x+1) m and the length of the diagonal FH is (4x+1) m. Find the area of the campsite
Answer:
168 m²
Step-by-step explanation:
A rectangle is a quadrilateral (four sides) with two pairs of equal opposite sides. All the four angles in a rectangle are equal to 90°.
Given the sides of rectangle FGHI as (3x + 6) m and (x+1) m and the diagonal as (4x + 1) m.
Hence, from Pythagoras theorem:
(4x + 1)² = (3x + 6)² + (x + 1)²
16x² + 8x + 1 = (9x² + 36x + 36) + (x² + 2x + 1)
16x² + 8x + 1 = 10x² + 38x + 37
16x² + 8x + 1 - (10x² + 38x + 37) = 0
6x² - 30x - 36 = 0
6(x² - 5x - 6) = 0
x² - 5x - 6 = 0
x² - 6x + x - 6 = 0
x(x - 6) + 1(x - 6) = 0
(x + 1)(x - 6) = 0
x = -1 or x = 6
since x cannot be negative, therefore x = 6
Sides are (3x + 6) = 3(6) + 6 = 24 m
(x + 1) = 6 + 1 = 7 m
Diagonal = 4x + 1 = 4(6) + 1 = 25 m
Area of camp site = side * side = 24 m * 7 m = 168 m²

If a polynomial function f(x) has roots 3 and StartRoot 7 EndRoot, what must also be a root of f(x)?
Answer:
–√(7) must also be a root of f(x)
Step-by-step explanation:
Given that the roots of an equation is 3 and √(7). This means that x = 3 or √(7). Therefore, the function is definitely going to be:
f(x) = (x – 3)(x² – 7)
This is because we are dealing with √(7) and what brought about √(7) was x² = 7.
If this is the case, we know that x² = 7 will give
x = ±√(7)
Hence, our roots are x = 3 or √(7) or –√(7). Therefore, –√(7) must also be a root of f(x).

Emily draws point C on the line segment so that the ratio of AC to CB is 3 to 1. What are the coordinates of Point C?
a. (-2,2.5)
b.(-1,2)
c.(3,0)
d.(4,-0.5)
Answer:
d.(4,-0.5)
Step-by-step explanation:
We are given that the ratio of AC to CB
AC:CB=3:1
[tex]m_1=3,m_2=1[/tex]
From given figure
The coordinates of A are (-5,4)
The coordinates of B are (7,-2)
We have to find the coordinates of C
Section formula:
[tex]x=\frac{m_1x_2+m_2x_1}{m_1+m_2},y=\frac{m_1y_2+m_2y_1}{m_1+m_2}[/tex]
Using the formula
The coordinate of point C are
[tex]x=\frac{3(7)+1(-5)}{3+1},y=\frac{3(-2)+1(4)}{3+1}[/tex]
[tex]x=\frac{16}{4},y=\frac{-1}{2}[/tex]
[tex]x=4,y=-0.5[/tex]
Hence, the coordinate of point C are (4,-0.5)
