Answer:

The numbers are 30, 60, and 10

Step-by-step explanation:

Let's start by assigning variables to the three numbers.

We can call them x, y, and z.

From the problem, we know that:x + y + z = 100

We also know that the first number is a multiple of 15, so we can write:

x = 15a, where a is some integer.

Furthermore, we know that the second number (y) is ten times the third number (z), so we can write:

y = 10z

Now we can substitute equations (2) and (3) into equation (1) to get an equation in terms of z:

15a + 10z + z = 100

Simplifying, we get:

15a + 11z = 100

To find a possible solution for this equation, we can try different values of a and see if we get a whole number solution for z.

Let's start with a = 1. Substituting a = 1, we get:

15(1) + 11z = 100

z = (100 - 15)/11

z = 8.64

Since z is not a whole number, we need to try a different value of a.Let's try a = 2.

Substituting a = 2, we get:15(2) + 11z = 100

z = (100 - 30)/11

z = 6

Now we have a whole number solution for z. Substituting z = 6 into equations (2) and (3), we get:x = 15a = 15(2) = 30

y = 10z = 10(6) = 60So the three numbers are 30, 60, and 10.

This should output: The value of the car in 2025 will be $11730.3 which function means that the value of the car in 2025 will be approximately $11,730.30.

A function appears to be a hyperlink between two sets of numbers in mathematics, where each member of the first set (referred as the domain) corresponds to a certain representative of the second set (called the range). In other utterance, a function takes input from a set and produces output by another. Inputs are frequently represented by the variable x, and outputs are represented by the variable y. A function can be represented by a formula or a graph. The method y = 2x + 1 is an example of a conceptual model in which each value assigned to x yields a value of y.

To calculate the value of the car in 2025, we need to determine the value of the car after each year of depreciation from 2020 to 2025. We can represent this situation using the following function:

[tex]value = 25000 * (0.86 ** years)\\ return value\\value_2025 = car_value(5)\\print("The value of the car in 2025 will be $" + str(round(value_2025, 2)))\\[/tex]

The total volume of the hemisphere mounted on the cuboid is 3574.76 cubic yards.

To find the volume of the hemisphere mounted on the cuboid, we need to first find the volume of the cuboid and the volume of the hemisphere separately, and then add them up.

The volume of the cuboid is given by the formula:

V_cuboid = l x w x h

where l, w, and h are the length, width, and height of the cuboid, respectively. Substituting the given values, we get:

V_cuboid = 17 yd x 14 yd x 12 yd

V_cuboid = 2856 cubic yards

Next, we need to find the volume of the hemisphere. The diameter of the hemisphere is given as 14 yd, which means that the radius is 7 yd. The volume of the hemisphere is given by the formula:

V_hemisphere = (2/3) x π x [tex]r^{3}[/tex]

V_hemisphere = (2/3) x 3.14 x [tex]7^{3}[/tex]

V_hemisphere = 718.76 cubic yards

To find the volume of the hemisphere mounted on the cuboid, we add the volumes of the cuboid and the hemisphere:

V_total = V_cuboid + V_hemisphere

V_total = 2856 + 718.76

V_total = 3574.76 cubic yards

The approximate diameter of the pile of sand in the cone that sand was dumped in is 9.30 feet.

What is the approximate diameter?

A cone is a 3-dimensional object that consists of a ciruclar base and a vertex. The diameter is twice the length of the radius.

Radius = √[volume / (1/3 x π x height)]

=> Radius=√[136 / (1/3 x 22/7 x 6)]

=> Radius=√[136 / 6.29 = 4.65

If the number of school districts in Indiana were proportional to the number of school districts in Illinois, we would expect to see 440 school districts in Indiana.

Ratios are used to compare different parts of a whole, to compare different amounts of something, or to compare different measurements of the same thing.

The expected number of school districts in Indiana can be calculated by using the population of the two states.

We know that Illinois has 859 school districts and 12.9 million people, and Indiana has 295 school districts and 6.6 million people.

To determine how many school districts we would expect to see in Indiana if they were proportional to the number in Illinois, we can set up a proportion:

⇒number of school districts in Indiana/number of school districts in Illinois = population of Indiana/population of Illinois

⇒number of school districts in Illinois/number of school districts in Indiana = population of Illinois/population of Indiana

We can rearrange this proportion to solve for the number of school districts in Indiana:

⇒number of school districts in Indiana/number of school districts in Illinois = population of Indiana/population of Illinois

⇒number of school districts in Illinois/number of school districts in Indiana = population of Illinois/population of Indiana

Substituting the given values, we have:

number of school districts in Indiana =

6.6/12.9×859 ≈ 440

number of school districts in Indiana=

12.9 /6.6 ×859≈440

According to the solution we have come to find that, There are 50 gallons of water in the tank after 15 minutes.

what is calculus?

Calculus is a branch of mathematics that deals with rates of change and how things change over time. It has two main branches: differential calculus and integral calculus.

Differential calculus deals with instantaneous rates of change and how things change at a particular moment or instant. It involves concepts such as derivatives, limits, and rates of change.

Integral calculus deals with the accumulation of quantities and how things add up over time. It involves concepts such as integrals, area under a curve, and accumulation of volumes.

a. To calculate the rate of change, we need to find the slope of the line connecting the two given points on the table. Using the formula for slope, we get:

slope = (change in y) / (change in x)

slope = (70 - 90) / (6 - 3)

slope = -20 / 3

Expressing the slope as a ratio, we get:

rate of change = -20/3

b. The rate of change is negative, indicating that the amount of water in the tank is decreasing over time. Water is leaving the tank. We know this because the slope of the line is negative, meaning that as time goes on, the amount of water in the tank is decreasing at a constant rate.

c. To find the amount of water in the tank after 15 minutes, we need to first find the equation of the line that passes through the two given points. Using the point-slope form of the equation of a line, we get:

y - 90 = (-20/3)(x - 3)

Simplifying, we get:

y = (-20/3)x + 110

Now we can substitute x = 15 to find the amount of water in the tank after 15 minutes:

y = (-20/3)(15) + 110

y = 50

Therefore, there are 50 gallons of water in the tank after 15 minutes.

This cathedral's ceiling features a standard octagon with a 64-foot diameter and a 10.5-foot radius. The apothem is roughly 9.7 feet long, while the normal octagon is roughly 310.8 square feet in size.

The perimeter of the octagon is the sum of the lengths of its sides, so each side has a length of 64/8 = 8 feet.

Draw a line from the centre of the octagon to the midpoint of one of its sides. This line segment is the apothem, which is also the radius of a triangle formed by two consecutive vertices and the centre of the octagon. This triangle is an isosceles triangle, with a base length of 8 and apothem 10.5. We may get the triangle's height using the Pythagorean theorem:

[tex]height^2 = \frac{apothem^2 - base^2}{4}[/tex]

[tex]height^2 = \frac{10.5^2 - 8^2}{4}[/tex]

[tex]height^2[/tex] = [tex]\frac{110.25 - 64}{4}[/tex]

[tex]height^2[/tex] ≈ [tex]\frac{46.25}{4}[/tex]

[tex]height[/tex] ≈ 9.7

So the length of the apothem is approximately 9.7 feet.

The area of the octagon is given by the formula A = (1/2)ap, where a is the apothem and p is the perimeter. With our current values substituted, we obtain:

A =(1/2)×9.7×64

A ≈310.8

A ≈310.8 [tex]ft^2[/tex]

So the area of the regular octagon is approximately 310.8 square feet.

The base 10 logarithmic function is a continuous function, which means that the distance between any two consecutive values on the number line is the same. Therefore, if 2 is halfway between 1 and 3, the value of the logarithm that is halfway between log 1 and log 3 should be the average of log 1 and log 3, which is:

(log 1 + log 3) / 2 = (0 + 0.477) / 2 = 0.2385

To find the value of x such that 10^x = 505, we can take the logarithm of both sides using base 10:

log 10^x = log 505

x = log 505

Using a calculator, we can find that log 505 is approximately 2.702.

To find the value of x such that 10^x = 100, we can take the logarithm of both sides using base 10:

log 10^x = log 100

x = log 100

Using a calculator, we can find that log 100 is exactly 2.

Therefore, the logarithm that is equal to 2 is log 100, not log 505.

Attribution theory provides a description of how people explain the causes of their own and others' behaviors. Option d is the correct choice.

The theory referred to in the question is attribution theory. Attribution theory explains how people make inferences about the causes of behaviors, events, or outcomes. It suggests that people usually make two types of attributions: dispositional (internal) and situational (external). Dispositional attributions refer to explanations based on the person's traits or characteristics, while situational attributions refer to explanations based on external factors or circumstances.

Attribution theory also describes how people make judgments about their own behavior and that of others. In summary, attribution theory is a social psychology theory that helps to understand how people explain the causes of behavior. Hence option d is correct.

You want a graph and the x-intercept of the line through (-3, 4) with y-intercept 1.

The slope formula gives you the slope you can use with the slope-intercept equation.

  m = (y2 -y1)/(x2 -x1)

One point is given as (-3, 4). The y-intercept is (0, 1), so the slope is ...

  m = (1 -4)/(0 -(-3)) = -3/3 = -1

Then the equation for the line is ...

  y = mx +b

  y = -1x +1

  y = -x +1 . . . . simplify

The x-intercept is the point that has y-coordinate 0:

  0 = -x +1

We are told that ∠2 is 16 more that 3 times ∠1.

Thus:

∠2 = 3(∠1) + 16

Thus:

3(∠1) + 16 + ∠1 = 180

4(∠1) = 180 - 16

It is the first option 4, 17, and 23

There is a rule of sides in a triangle that states "the sum of the lengths of two sides is always greater than the third side"

so how you would solve this is by process of elimination. Add two lengths from each number set to see if they follow the rule.

When you do this, all of the number sets follow the rule except for the first one, because 4 plus 17 is 21, and it is less than 23. This means it does not follow the rule.

f(b) = f(8) = 6 ← point (8, 6 ) on graph

f(a) = f(- 5) = 0 ← point (- 5, 0 ) on graph

then

average rate of change = [tex]\frac{6-0}{8-(-5)}[/tex] = [tex]\frac{6}{8+5}[/tex] = [tex]\frac{6}{13}[/tex]
