If i had 1 apple and another apple how many apples would i have?

Step-by-step explanation:

yes, they are, because both triangles have the same 3 angles :

the right angle = 90°

65°

25°

now, the side lengths can be different, but because of the same angles, the ratio between the corresponding side lengths will be the same for all sides (e.g. if one pair of sides has the scaling factor of 3 from the smaller to the larger triangle, then the other pairs will also have the same scaling factor 3).

that is the difference between equivalent and similar : for "equivalent" also the side lengths must be the same.

for "similar" only the angles need to be the same.

The correct that represents the total amount of popcorn, in quarts, produced by x scoops of unpopped kernels

If 3 scoops of unpopped kernels produce 6 quarts of popcorn, we can find the rate of popcorn produced per scoop by dividing the total popcorn by the number of scoops:

One centimeters is equal to 0.01 meters. Centimeter (cm) and meter (m) are both units of length in the International System of Units (SI).

One centimeter is equal to 0.01 meters.

This can be derived by using the conversion factor that 1 meter is equal to 100 centimeters:

1 meter = 100 centimeters

Dividing both sides by 100, we get:

1 centimeter = 1/100 meters

Simplifying this, we get:

1 centimeter = 0.01 meters

Therefore, one centimeter is equal to 0.01 meters.

A centimetre is a metric length unit that equals one tenth of a metre. It is typically used to measure short distances, such as an object's length or width, or a person's height.

When x = 6 and y = -4, the value of of the expression 50-3(x²-y²)+x is -4.

An algebraic expression is when we use numbers and words in solving a particular mathematical question.  The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.

Substitute x=6 and y=-4 into the expression 50-3(x²-y²)+x:

50 - 3(6² - (-4)²) + 6

= 50 - 3(36 - 16) + 6

= 50 - 3(20) + 6

= 50 - 60 + 6

= -4

Hence, when x = 6 and y = -4, the value of 50-3(x²-y²)+x is -4.

We can estimate that about 98 million more megawatt hours were generated from wind in 2020 than in 2016.

What is Division?

Division is a mathematical operation that involves splitting a quantity into equal parts or groups. It is the inverse operation of multiplication and is represented using the division symbol ÷ or the forward slash /.

Solution:

To estimate how many more megawatt hours were generated from wind in 2020 than in 2016, we need to make some assumptions and approximations since the problem only provides data for 2009 and 2017.

Assuming that the wind energy generation continued to increase at the same constant rate between 2017 and 2020, we can estimate the amount of wind energy generated in 2020 as follows:

1. From 2009 to 2017, the wind energy generation increased by 254 million - 74 million = 180 million megawatt hours.

2. The time period between 2009 and 2017 is 8 years, so the average annual increase in wind energy generation is 180 million / 8 years = 22.5 million megawatt hours per year.

3. Therefore, we can estimate the wind energy generation in 2020 as 254 million + 3 years x 22.5 million = 322.5 million megawatt hours.

4. Similarly, we can estimate the wind energy generation in 2016 as 74 million + 7 years x 22.5 million = 224.5 million megawatt hours.

5. The difference in wind energy generation between 2020 and 2016 is then:

322.5 million - 224.5 million = 98 million megawatt hours.

Therefore, we can estimate that about 98 million more megawatt hours were generated from wind in 2020 than in 2016.

In mathematics, an equation is a statement that asserts the equality of two expressions. It consists of two expressions separated by an equals sign (=). The expression on the left side of the equals sign is called the left-hand side (LHS), and the expression on the right side of the equals sign is called the right-hand side (RHS). Solving an equation means finding the value of the variable that makes the equation true. I

Here,

A circle with diameter 12 units and center on the y-axis has its center at (0, c), where c is a constant. The radius of the circle is half the diameter, which is 6 units.

The equation of a circle with center (0, c) and radius r is given by:

Answer:

35.35 seconds

Step-by-step explanation:

The volume of the cylindrical glass can be calculated as:

V = πr²h

where r is the radius (half of the diameter), h is the height, and π is the mathematical constant π (approximately 3.14).

Since the diameter is 3 inches, the radius is 1.5 inches. The height is 10 inches. Therefore, the volume of the glass is:

V = π(1.5)²(10) ≈ 70.69 cubic inches

To fill the glass 50%, we need half of the volume:

V/2 ≈ 35.35 cubic inches

The faucet dispenses water at a rate of 1 cubic inch per second, so the time it takes to fill the glass 50% is:

t = (V/2) / (1 cubic inch per second) ≈ 35.35 seconds

Therefore, it takes approximately 35.35 seconds to fill the glass 50%. Rounded to two decimal places, the answer is 35.35 seconds.

The rate of change of the area of a circle with respect to its radius when r = 3 cm is 6π cm2/cm, and the rate of change of the area of a circle with respect to its radius when r = 4 cm is 8π cm2/cm.

The area of a circle can be calculated using the formula, A = πr^2, where A is the area of the circle and r is the radius.The rate of change of the area of a circle with respect to its radius r can be calculated using the derivative of the equation. By taking the derivative of A with respect to r, we get the equation, dA/dr = 2πr.This equation signifies that the rate of change of the area of a circle with respect to its radius is proportional to the radius. As the radius increases, the rate of change of the area of the circle also increases.To calculate the rate of change of the area of a circle with respect to its radius when r = 3 cm and r = 4 cm, we can substitute the corresponding values of r in the equation, dA/dr = 2πr.

For r = 3 cm, the rate of change of the area of the circle with respect to its radius is dA/dr = 2π(3) = 6π cm2/cm.

For r = 4 cm, the rate of change of the area of the circle with respect to its radius is dA/dr = 2π(4) = 8π cm2/cm.

Therefore, the rate of change of the area of a circle with respect to its radius when r = 3 cm is 6π cm2/cm, and the rate of change of the area of a circle with respect to its radius when r = 4 cm is 8π cm2/cm.

Answer:

The correct answer is (A) 96 and 84. When y is directly proportional to x, it means that the ratio of y to x remains constant. In this case, when x=9, y=108, which means that the ratio of y to x is 108/9. Since the ratio is constant, we can use that ratio to find the values of y when x=8 and x=7. When x=8, y = (108/9)x8 = 96 and when x=7, y = (108/9)x7 = 84.
