I had $13.00. My mom gave $10.00 my dad gave $30. My Aunt, My uncle and grandma gave me $100. I had another $7.00. How much did I have?

Answer:

3600 watt-hours consumed per day.

Step-by-step explanation:

First we'll want to find how many hours are in 3 days and 6 hours.

3 x 24 = 72 + 6 = 78

78 hours is 3 days and 6 hours.

We then divide 11700 by 78 to find out how many watt-hours it will consume per hour.

11700 / 78 = 150

Now that we know how many watt-hours it will consume per hour, we can multiply it by 24 to find out how many it will consume in a day.

150 x 24 = 3600

Answer:

4x² - 16.

Step-by-step explanation:

(2x-4)² =?

(2x-4)² = (2x)² - (4)²

= 4x² - 16.

Answer:

x = 2

Step-by-step explanation:

To solve , equate to zero, that is

(2x - 4)² = 0, so

2x - 4 = 0 ( add 4 to both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Answer:

Both are equal to [tex]\frac{1}{16}[/tex]

Step-by-step explanation:

If the exponent is negative we can turn it into a fraction and make it positive.

This means the number goes to the denominator and the numerator becomes one. Therefore the following.

[tex]4^{-2} = \frac{1}{4^{2} } =\frac{1}{16}[/tex]

[tex]2^{-4} =\frac{1}{2^{4} } = \frac{1}{16}[/tex]

Step-by-step explanation:

3-r/8=-9/2

r/8=3-(-9/2)

r/8=3+9/2

Answer:

x*(x+3)*(x^2)

Step-by-step explanation:

Width: x meters, length: x + 3 meters, height x^2 meters

It's an expression, so there's no simplifying needed.

x(x+3)(x^2)

But if I'm wrong and it's supposed to be simplified, Read the rest.

First, multiply x by x + 3

x(x + 3)

x^2 + 3x

Now, multiply x^2 + 3x by x^2

(x^2)(x^2 + 3x)

x^4 + 3x^3

Answer:

x = -1.791 and x = 2.791

Step-by-step explanation:

To solve this problem, we have to plot this graph using  tool so we also know which of the lines is right.

The solution to this equation is at -1.791 and +2.791 and the graph that looks like the equation is the line in green color.

A given quadratic equation is an equation that has the highest degree of 2. Further more, when plotted on a graph, it has a parabolic shape.

The given equation is

[tex]3= x^2 - x - 2\\y = x^2 - x -5[/tex]

Let's proceed to plot this graph and we would see the solutions at the point in which the lines curves.

Using that, the solution to this equation is at -1.791 and +2.791 and the graph that looks like the equation is the line in green color.

The solution are

Answer:

f(10) = -130

Step-by-step explanation:

f(x) = -x² - 3x

f(10) = -(10)² - 3(10)

f(10) = -100 - 30

f(10) = -130

The original price of the racket is $30

Let the original price be x

If there is 30% off the original price, then the new price will  be 0.7x

If the price of tennis racquet is now $21, hence;

0.7x = 21

Divide both sides by 0.7

0.7x/0.7 = 21/0.7

x = 21/0.7

x = $30

Hence the original price of the racket is $30

Answer:

12s^2 - s - 20

Step-by-step explanation:

It's simplest form is when it's fully expanded.

To expand: (3s-4)(4s+5)

(3s * 4s) + (3s * 5) + (-4 * 4s) + (-4 * 5)

= 12s^2 + 15s -16s -20

= 12s^2 - s - 20

Step-by-step explanation:

3+2y-24=14-3y

first solve 3+2y-24 by collecting like terms together

2y+3-24

2y-21

substitute (2y-21) into 3+2y-24=14-3y

2y-21=14-3y

collect like terms together

2y+3y=14+21

5y=35

5y/5=35/5

y=7

Answer:

See explanations below

Step-by-step explanation:

Given the equation

6x-9 = 15

Add 9 to both sides

6x-9+9 = 15+9

6x = 24

x = 24/6

x = 4

For the equation

16x - 20 = 44+ 5x

Since we have x variables on both sides, we will collect the like terms

16x - 5x = 44+20

11x = 64

Divide both sides by 11

11x/11 = 64/11

x = 64/11

x = 5.82

Hence the value of x is 5.82

Answer: It's an acute triangle.

Step-by-step explanation: I have the same problem, and I tried each choice, acute was the correct answer

The triangle with side lengths 8, 12, 14 is an obtuse triangle.

A triangle is a three-sided polygon that consists of three edges and three vertices.

To determine whether the triangle is acute, obtuse, or right, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.

8² + 12² = 64 + 144 = 208

14² = 196

Since 208 is greater than 196, we can see that the triangle does not satisfy the Pythagorean theorem. Therefore, the triangle is not a right triangle.

Since the longest side is 14 and the sum of the squares of the two shorter sides is less than the square of the longest side, we can conclude that the triangle is obtuse.

Therefore, the triangle with side lengths 8, 12, 14 is an obtuse triangle.
