Can somebody help me? Thanks

Answer:

the answer is E

Step-by-step explanation:

We want to find how many integers are between 2020 and 2400 such that a criteria is meet, and the criteria is that the four digits are different and are arranged in increasing order.

We will see that there are 15 of these numbers between 2020 and 2400, so the correct option is C.

---------------------------

To count the number of digits that meet the given criteria, we first need to analyze how the criteria is.

If the numbers must be in increasing order, then the smallest number that can be in the hundreds place is 3 (the smaller integer larger than 2).

so we have:

23__

The number next to the 3 can be a 4, for example:

234_

And the final number can be any number larger than 4, so we have {5, 6, 7, 8, 9} a total of 5 options.

If instead of a 4, the number next to the 3 is a 5, we have:

235_

And the number next to the five can be any digit larger than 5, so now we have 4 options.

Now, we can't have another number than a 3 in the hundreds place, because if we put a 4 there, we are out of the range, and 3 is the smallest digit that we can use there.

Then we already saw all the possible numbers that we can make, adding the numbers of options that we got above we will get:

5 + 4 + 3 + 2 + 1 = 15

This means that are 15 of these numbers between 2020 and 2400. Then the correct option is C.

Answer:

$150.66

Step-by-step explanation:

Let that amount of money Roger has = x

The amount of money Roderick has = y

Roger has four dollars more than double the amount that Roderick has in his wallet.

x = 2y + 4

Together, they have a total of $224.

x + y = $224....... Equation 1

We substitute 2y + 4 for x in Equation 1

2y + 4 + y = $224

3y + 4= $224

3y = $224 - 4

3y = $220

y = $220/3

y = $73.333333333

y = $73.33

How much money does Roger have?

x = 2y + 4

x = 2(73.33) + 4

x = $146.66 + 4

x = $150.66

Roger has $150.66

Answer:

  y = 26

Step-by-step explanation:

You have already correctly solved for x, so you know that ...

  m∠8 = 4(17)+10 = 78

Angle 12 is an alternate interior angle with respect to angle 8, so is congruent to angle 8.

  m∠12 = m∠8

  3y = 78

  y = 78/3 . . . . divide by the coefficient of y

  y = 26

Answer:

Assuming its "Modeling a Water Wheel" from EDGE its

Distance: a= 1/2 b=1 c=3/2

Heights: d=1  e=0  f=-1

Step-by-step explanation:

The solution is, a = 6, b = 7, c = 8, d = 7 and e = 6.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

Let's remember that the complete revolution of the wheel is 360 degrees, and the distance traveled by a complete revolution is the length of the circumference: 2*pi*radius.

The inicial height of the point is 6 ft, and the radius of the wheel is 1 ft.

When the distance traveled is 0, the wheel turned 0 degrees, and the point will be in its inicial position (the lower position of the wheel), which is 6 feet high.

So the height will be a = 6 + 0 = 6 ft

When the distance traveled is pi/2, the wheel turned 90 degrees, and the point will be half the complete height of the wheel, which is 2 feet.

So the height will be b = 6 + 1 = 7 ft

When the distance traveled is pi, the wheel turned 180 degrees, and the point will be at the top of the wheel, which is 2 feet higher than the lower point of the wheel.

So the height will be c = 6 + 2= 8 ft

When the distance traveled is 3pi/2, the wheel turned 270 degrees, and the point will be half the complete height of the wheel, which is 2 feet.

So the height will be d = 6 + 1 = 7 ft

When the distance traveled is 2pi, the wheel turned 360 degrees, and the point will be in its inicial position (the lower position of the wheel), which is 6 feet high.

So the height will be e = 6 + 0 = 6 ft

So the answers are:

a = 6, b = 7, c = 8, d = 7 and e = 6

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

y ∝ x

y = kx

Where k is a constant and it can be any integer.

If y varies directly with x.

Yes, it is possible to determine by how much y increases or decreases as x increases.

If x increases by 2 then y also increases by 2.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

y varies directly with x.

This can be written as an equation,

y ∝ x

y = kx

Where k is a constant and it can be any integer.

Now,

If x increases by 2.

y = 2k

If k = positive integer

Then y will increase by 2k.

If k = negative integer

Then y will decrease by -2k

So,

Yes, it is possible to determine by how much y increases or decreases.

Thus,

Answer:

y = 5x + 9

Step-by-step explanation:

Assuming you require the equation of the line.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5, thus

y = 5x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = - 5 + c ⇒ c = 4 + 5 = 9

y = 5x + 9 ← equation of line

Answer: x= -10

Step-by-step explanation:

Let's solve your equation step-by-step.

6x−9=8x+11

Step 1: Subtract 8x from both sides.

6x−9−8x=8x+11−8x

−2x−9=11

Step 2: Add 9 to both sides.

−2x−9+9=11+9

−2x=20

Step 3: Divide both sides by -2.

−2x /-2= 20/-2

x=−10

Answer:

The answer is 3

Step-by-step explanation:

The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope of a line that passes through (x₁, y₁) and (x₂, y₂) is,

Slope = (y₂ - y₁)/(x₂ - x₁)

Since the given line is passing through (0,0) and (3,9).

Slope = (9 -0)/(3 - 0)

Slope = 3

Since the line is passing through the origin (0,0) so we can do it by mental math to divide y and x coordinate directly like 9/3 = 3.

Hence "The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3".
