Answer:

2

Step-by-step explanation:

The equation is mx+b=y

The equation is not simplified yet.

2y-4x=1

Add 4x to both sides

2y=1+4x

Divide by 2

1/2+2x

For this just identify. M=slope. The number next to the x is 2. So the answer is 2

Answer:

Slope is 2: y = 2x + 1/2

Step-by-step explanation:

2y - 4x = 1

    + 4x   + 4x (Add 4x to both sides to leave y by itself on one side)

------

2y/2 = 4x/2 + 1/2 (Divide both sides by 2 in order to leave y with no coefficient)

y = 2x + 1/2

Answer:

11

Step-by-step explanation:  Since the question does not specify wether the temperature dropped every hour or if it was the total, in this case we can assume this was in total. If you ended up with -2 after subtracting 13, to get the starting temperature you can add -2 to 13.

-2 + 13 = 11

Answer: XYZ = 144 degree

Step-by-step explanation:

The non overlapping angles are said to be adjacent angles of a common vertex and a common side but do not overlap.

If WYZ has a measure of 32 degree.

And XYW has a measure of 112 degree

Then, the measure of XYZ will be

XYZ = WYZ + XYW

XYZ = 32 + 112

XYZ = 144 degree

Step-by-step explanation:

Answer:

Step-by-step explanation:

The radius of the sphere with a volume of 32/81 π cubic yards is 2/3 yards. This is found by equating the given volume to the volume of a sphere formula and solving for the radius step-by-step.

To find the radius of a sphere given its volume, we can use the formula for the volume of a sphere, which is V = (4/3)πr³. In this case, we have the volume V= 32/81 π cubic yards. We need to solve for r (the radius).

First, we set the given volume equal to the volume formula:

32/81 π = (4/3)πr³

To solve for r³, we divide both sides by (4/3)π:

r³ = (32/81 π) / ((4/3)π) = (32/81) / (4/3) = 32/81 * 3/4 = 32/108 = 8/27

Now, to find r, we take the cube root of both sides:

r = ³√(8/27)

Since ³√8 = 2 and ³√27 = 3, the radius r is 2/3 yards.

It appears the first two digits in the code is the two digits out front multiplied together. The next digit or two are the sum of the two numbers. The last number or two is the difference.

7x3 = 21

7+3 = 10

7-3 = 4

(7)(3) = 21104

It's the same process for the (9)(4) = 36135

So for (8)(5) would be:

8x5=40

8+5=13

8-5=3

(8)(5)= 40133

Answer:

40133

Step-by-step explanation:

Basically,

The first 2 digits you multiply 8 and 5. Which is 40. Then you add 8 and 5 which is 13. Then subtract 8 and 5 which is 3.

So putting them together you get 40133

The probability of a dart hitting the yellow region of the target can be calculated by determining the area of the yellow region, in this case about 1130.97 cm^2, and dividing it by the total area of the target, which is about 1385.44 cm^2. The resulting probability is approximately 0.82, or 82%.

To solve this, we must first understand that the probability of the dart hitting a certain zone on the target will be proportional to the area of that zone. In this case, the entire area of the target is the area of the circle with a diameter of 42 cm. The radius of the target, therefore, is 21 cm.

The formula for the area of a circle is πr^2, so the area of the target is π * (21)^2, or about 1385.44 cm^2.

While the yellow zone is the ring with 18 cm diameter. Using the formula for the area of a circle again, the inner boundary of the yellow zone will have an area of π * (9)^2, or about 254.47 cm^2. The area of the yellow zone is the difference between these two values, which is around 1130.97 cm^2.

To find the probability of a dart hitting the yellow zone, we divide the area of the yellow zone by the total area of the target. This gives us a probability of around 0.82, or 82%.

Answer:

1,436 with a remainder of 4

Step-by-step explanation:

The first step is to see how many times 6 goes into 8

It goes in 1 time so you write 1 at the top and subtract 6 from 8

This gives you 2, and then you bring down the 6 from the 8,620

Now you have 26, and you see how many times 6 goes into 26

It goes in 4 times giving you 24 so you write 4 at the top

Then you subtract 24 from 26 giving you 2 and you drop down the 2

This gives you 22 and 6 goes into 22 3 times giving you 18

So you write 3 at the top and subtract 18 from 22 giving you 4

then you drop down the 0 from the 8,620 giving you 40

Then you evaluate how many times 6 goes into 40, it goes in 6 times

this gives you 36 and then you writes a 6 at the top and subtract 40 and 36

this gives you a remainder of 4

It's still negative because the positive number is not equal nor greater than the negative number so it's still negative.

To find Brianna's new quiz score after correcting a mistake, we can use two mathematical operations: 90 + 4, which adds the points back directly, or 90 - (-4), which mathematically corrects the wrongful deduction by subtracting a negative.

The question involves finding Brianna's new quiz score after correcting a mistake. At first, she earned a score of 90 on the quiz, but then discovered that 4 points had been taken off by mistake. To correct this, we should add the 4 points back to her original score of 90.

The correct mathematical operation to use would be 90 + 4, because we are adding back the points that were mistakenly deducted. Another way to express this correction is by removing the negative effect of the 4-point deduction, which mathematically would look like 90 - (-4). When we subtract a negative, it is equivalent to adding the positive value of that number.

Therefore, the two quiz scores that could be used to find Brianna's new quiz score are:

Final answer:

The correct options for calculating Brianna's new quiz score after the mistake is corrected are (2) 90 + 4 and (4) 90 - (-4), both of which correctly add 4 points to the original score of 90.

Explanation:

The correct way to calculate Brianna's new quiz score after the mistaken 4-point deduction is revoked would be by taking the original score of 90 and adding the 4 points back. Therefore, the two quiz scores we could use to find Brianna's new quiz score are:

90 + (-4), which is subtracting the 4 points that were mistakenly deducted, but since we want to reverse that deduction, this would not be used.

90 + 4, which correctly adds the 4 points back to the original score.

90 - 4, which would mistakenly subtract 4 more points instead of adding them back.

90 - (-4), which is essentially the same as adding 4 to 90, and it also gives the correct new score.

We disregard the options that subtract 4 points. Therefore, the correct options to use for finding Brianna's new quiz score are (2) 90 + 4 and (4) 90 - (-4).

Answer:

A. 6.2 X 10 ^-3

Step-by-step explanation:

First, you have to find the total weight by adding 0.0002 and 0.006 together, which gives you 0.0062. Then, follow basic setup of scientific notation by moving the decimal until one non-zero digit is to the left of the decimal, which brings the decimal to 6.2. Since you are moving the decimal right three places, the exponent is negative 3, making the notation 6.2 X 10 ^-3

The slope between the points (8,-4) and (2,-4) is 0, indicating a horizontal line.

To find the slope between two points, you use the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Let's apply this formula to the points given: (8, -4) and (2, -4).

Slope (m) = (-4 - (-4)) / (2 - 8) = (0) / (-6) = 0

Since the numerator of the slope formula is zero, the slope of the line passing through these two points is 0, which indicates a horizontal line.

Answer:

[tex]x = \dfrac{36}{y}[/tex]  

Step-by-step explanation:

We are given the following in the question:

x and y vary inversely.

[tex]x\propto \dfrac{1}{y}[/tex]

Removing the sign of proportionality and adding the constant of proportionality, we get,

[tex]x = k\times \dfrac{1}{y} = \dfrac{k}{y}[/tex]

where k is the constant of proportionality.

When x = 3, y = 12

Putting these value in the equation, we get,

[tex]3 = \dfrac{k}{12}\\\\\Rightarrow k = 12\times 3 = 36[/tex]

Putting value of k, we get,

[tex]x = \dfrac{36}{y}[/tex]

which is the required equation to model the given situation.
