Find the sum of all 3-digit multiples of 10

Answer:

no

Step-by-step explanation:

The value of the angle ∠PRQ using sine rule is;  36.9°

The sine rule is a rule in trigonometry that states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle.

Thus;

a/sin A = b/sin B = c/sin C

Now, applying the sine rule to the given problem, we can say that;

130/sin ∠PRQ = 187.5/sin 60

sin ∠PRQ = (130/187.5) * sin 60

sin ∠PRQ = 0.6

∠PRQ =  sin⁻¹0.6

∠PRQ = 36.9°

A linear graph is a graph in which the data points are distributed along a straight line, and the relationship between the variables is represented by a linear equation.

A nonlinear graph is a graph in which the data points are not distributed along a straight line, and the relationship between the variables is represented by a nonlinear equation.

A linear equation is an equation that can be written in the form of y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of the line represents the rate of change of the dependent variable y with respect to the independent variable x. A graph that follows a linear equation will be a straight line.

On the other hand, a nonlinear equation is an equation that cannot be written in the form of y = mx + b. The relationship between the variables in a nonlinear equation is more complex and can be represented by a curve on a graph. The shape of the curve can vary and can be determined by the specific equation being used.

In summary, a linear graph is a graph that shows a straight line relationship between the variables, while a nonlinear graph is a graph that shows a more complex, curved relationship between the variables.

The required function for the given values of x and y is  y = 16/x.

If two quantities are inversely related, one will increase while the other will decrease. Building a wall would be an example of an inverse proportion in action. The time it takes to construct a wall decreases as more people work on it.

We have,

x = 2 and y = 8

Then

y ∝ 1/x

y = k/x

K is constant

So, Putting the values

Answer:

Simple interest is calculated by multiplying the principal amount (the initial deposit) by the interest rate and the number of years.

The formula for simple interest is:

I = P * r * t

Where:

I = Interest

P = Principal (initial deposit)

r = Interest rate (expressed as a decimal)

t = Time (in years)

In this case, the principal amount is $500.00, the interest rate is 4.5% (converted to 0.045), and the time is 15 years.

We can plug in the values into the formula:

I = $500.00 * 0.045 * 15 = $337.50

So, after 15 years with the same interest rate, Arisia’s account would earn $337.50 in interest.

A state function is a property that depends only on the current state of the system, and not on the path taken to reach that state.

Examples of state functions include temperature, pressure, volume, and internal energy, and they can only be measured if a substance undergoes a phase change.

A state function is a property of a system that depends only on the current state of the system, and not on the path taken to reach that state. In other words, a state function is a property that is path-independent. This means that the value of a state function does not depend on how the system arrived at its current state, only on the current state itself.

One way to think about state functions is to compare them to non-state functions, also known as path functions. A non-state function, such as work or heat, depends on the path taken to reach the current state of the system. For example, the amount of work done on a gas in a piston can be different depending on the path taken to compress the gas. If the gas is compressed slowly, the amount of work done will be less than if it were compressed quickly. However, the internal energy of the gas, which is a state function, will be the same regardless of the path taken to compress it.

According to the given information in the question the value of x is 85. Hence answer will be x = 85.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Here, we have

Given: Angle FGH is a straight angle.

The measure of angle FGJ is 95°.

The measure of angle JGH is x°

Angles that form a straight line add up to equal 180°

There is a probability of 0.64 that Hugo buys more than 2 packs to get the card of his favorite player.

Therefore P( X > 2) is 0.64.

The random variable X in this situation represents the number of packs of baseball cards that Hugo buys before he gets the card of his favorite player. Since Hugo can buy at most 4 packs and the probability of getting the desired card in each pack is 0.2, we can use this information to create the probability distribution for X.

Here is the probability distribution for X using binomial distribution:

X > 4: The probability that Hugo does not get the card in any pack is

= (1 - 0.2)⁴

= 0.4096

X = 1: The probability that Hugo gets the card in the first pack is

= 0.2

X = 2: The probability that Hugo gets the card in the second pack is

= (1 - 0.2)(0.2)

= 0.16

X = 3: The probability that Hugo gets the card in the third pack is

= (1-0.2)²(0.2)

= 0.128

X = 4: The probability that Hugo gets the card in the fourth pack is

= (1-0.2)³(0.2)

= 0.1024

Probability that Hugo has to but more than 2 pack is

P( X>2) = P(3) + P(4) + P(X > 4)

All the statements for the account balances are true.

Since the balance of Sam's account, y, based on the number of weeks spent saving, x, can be represented by y = 35x+10.

We can also represent his sister's account with equation as follows.

The general form of  the equation of a line is given by y = mx+b,

where m is the slope (rate) and b is the y-intercept (starting point)

From the graph:

Sam's sister starts with $60 i.e. b = 60

The amount she saved per week can be found by calculating the slope.

Slope = (y₂-y₁) /(x₂-x₁)

Using x₁= 0, y₁ = 60 and x₂ = 2, y₂ = 120

Slope = (120-60) /(2-0)  = 60/2 = 30

y = mx+b

y = 30x + 60

After 5 weeks:

For Sam:

y=35x+10

y=35(5) +10 = $185

For his sister:

y = 30x + 60

y = 30(5) + 60 = $210

Part A: The volume of the small fish tank is 576 cubic inches.

Part B: The length of the large fish tank is 24 inches.

Part A:

The volume of the small fish tank can be found by multiplying its length, width, and height.

Length x Width x Height
= 12 inches x 8 inches x 6 inches
= 576 cubic inches

Part B:

We know that the large fish tank's volume is two times that of the small fish tank. So:

The volume of the large fish tank

= 576 cubic inches x 2 = 1152 cubic inches

We also know that the width and height of the large fish tank are the same as the small fish tank (8 inches and 6 inches respectively). So we can use the formula for volume (length x width x height) to find the length(L) of the large fish tank:

1152 cubic inches = L x 8 inches x 6 inches

                             = L x 48 inches²

To convert the above equation "x+9+18=0" to quadratic equation form, we must transfer all of the terms to one side of the equation and set it equal to 0.

The following equation may be rewritten: x+9+18 = 0.
