Step 1: 8 + 16x
Step 2: 4(4) + 4(12x)
Step 3: 4(4 + 12x)
Step 4: Dimensions of the rectangle are 4 and 4 + 12x


In which step did the student first make an error and what is the correct step?

1)

Step 3; 4 + (4 + 12x)


2)

Step 3; 4 + (4 ⋅ 12x)


3)

Step 2; 4(2) + 4(4x)


4)

Step 2; 4(2) + 4x(2)

Answer:

vertical; x=25

4x-25=75

4x=75+25=4x=100

4x/4=100/4 x=25

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

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.

Answer:

x < 1

Step-by-step explanation:

To solve for x, we need to get x by itself

2(5 - x)>8

Distribute the 2

2*5 -2*x >8

10- 2x >8

Subtract 10 from both sides

10-10 -2x >8 -10

-2x > -2

Divide both sides by -2

-2x/-2> -2/-2

Since we divided by a negative number, we must flip the inequality sign

x < 1

Answer:

x < 1

Step-by-step explanation:

Given

2(5 - x) > 8 ( divide both sides by 2 )

5 - x > 4 ( subtract 5 from both sides )

- x > - 1

Multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.

x < 1

Answer: x=10 and x= 3.66667

Step-by-step explanation:

you would need to at 110 to both side to get c before you can solve the quadratic formula, once you have done that you should get 3x2-41x+110=0 than you can now put it in to the formula(-b[tex]\frac{-b(+-)\sqrt{b^{2-4ac} } }{2a}[/tex]) which will now be [tex]\frac{-(-41)(+-)\sqrt{41^{2-4(3)(110)} } }{2(3)}[/tex]  than solve [tex]\frac{41(+-)\sqrt{1681-1320} }{6}[/tex] now combined to get [tex]\frac{41(+-)\sqrt{361} }{6}[/tex] the discriminant [tex]b^{2}[/tex]-4sc > 0 so there are two real roots which are, [tex]x= \frac{41(+-) 19}{6}[/tex]  simplify the radicals, x [tex]\frac{60}{6}[/tex]=  and x = [tex]\frac{22 }{6}[/tex] that will turn into x = 10 and x= 3.66667

Answer: 4

Step-by-step explanation:

Simply plug in each answer choice

320(pi)= 1005.309

pi x 4^2 x 20= 1005.309

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

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

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

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%.

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.

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.
