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

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).

Answer: $4.64

Step-by-step explanation:

The first ounce is charged at $0.79 and then every additional ounce is $0.55.

There are 8 ounces to send.

The cost will therefore be:

= Cost of first ounce + Cost of 7 additional ounces

= 0.79 + (0.55 * 7)

= 0.79 + 3.85

= $4.64

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.

We are given radius, r = 7 inches

We know that :

Circumference = 2πr

⟹ Circumference = 2π × 7 inches

⟹ Circumference = 14π inches

Hence, circumference of circle is 14π inches.

Answer:

151

Step-by-step explanation:

Volume of a cone can be found using the equation below

V=π(r^2)(h/3)

divide diameter by two to find the radius: 8/2=4

Plug the values into the equation: V=π(4^2)(9/3)

Simplify

V=π(4^2)(9/3)

V=π(16)(3)

V=150.79

Rounds up to 151

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.

Since we are talking about money, we are often expected to round to the nearest cent.  So the cost-per-unit is $.06

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

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

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)

Step-by-step explanation:

3÷1.5 = 2

10÷2 =5

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

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

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%

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
