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:

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:

It will go up.

Step-by-step explanation:

Since blakes personal "mean" is 80% then the average will go up.

Answer:

To find the "Unit rate" you need to find the price for one ounce.  So, you need to divide 1.29 by 20.

When you do this you get the following decimal

0.0645

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:

$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

Step-by-step explanation:

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:

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)

Option d is true.

Answer:

The coordinates of H after the dilation is (-6,6)

Step-by-step explanation:

Here, we want to get the coordinates of the image given the coordinates of the pre-image

with the dilation factor and the coordinates, what we have to do is to simply multiply each of the coordinates of the point on the vertex by 3

Mathematically, we have this as;

H’ = 3H

so;

(-2,2) becomes; (3 * -2, 3 * 2) = (-6,6)

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.

Step-by-step explanation:

Given

3(3x - 4) - 2(2x - 1)

= 9x - 12 - 4x + 2

= 5x - 10

= 5(x - 2)

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

Answer:

b) $4.60

Step-by-step explanation:

a)

2 panels at $923.40 each = $1846.80

Total with installation: $1944.80

Installation $1944.80-$1846.80 = $98

b)

2 panels at $940.50 each = $1881.00

Total with installation: $1983.60

Installation $1983.60-$1881.00 = $102.60

Substract a from b

102.60-98 = 4.60

Paul went to a solar panel store and paid $923.40 per solar panel for two solar panels and a flat rate fee for installation for a total of $1944.80. Brad went to another solar panel store and paid $940.50 per solar panel for two solar panels plus a per solar panel installation fee for a total of $1983.60.

4(3)+12=24, which is less than 28, so the inequality would be true

Answer:

The answer is A)3

Step-by-step explanation:

4 multiplied by 3 is 12, 12+12 is 24, less than 28

2 multiplied by 6 is 24+12 is 36, greater than 28

4 multiplied by 7 is 28, already over 28

4 multiplied by 10 is 40 is already way over 28

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:

yes you can simplify it because both the denominators have common denominator of 15.

Answer:

Yes

Step-by-step explanation:

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

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).

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.
