Answer:

4w+4=-6

4w=-6-4

4w=-10

4w/4=-10/4

w=-2.5

Answer:

5.5 or simply 6

Step-by-step explanation:

6 = 33

1 = x

6x = 33

x = 5.5 ~6

Answer:

The answer is "2.5".

Step-by-step explanation:

[tex]\to \frac{(25-24.5)}{0.2}= \frac{(0.5)}{0.2}=2.5[/tex]

The pieces which does not achieve that specific weight either are below and above the average standard deviation of 2.5. The percentage of components not fulfilling their weight data is 1.1% using a Table of Z-scores.

The coordinates of the point on the unit circle at angle 225° are [tex]\bold{(-\frac{\sqrt{2} }{2}, -\frac{\sqrt{2} }{2})}[/tex]

The coordinates of the points of the circle x² + y² = r² are [tex](r~cos\theta, r~sin\theta)[/tex]

"It is a circle with radius 1."

For given example,

We have been given an angle of 225°

⇒ [tex]\theta[/tex] = 225°

We need to find the coordinates of the point on the unit circle at an angle 225°.

Here, r = 1

So, the first coordinate would be,

[tex]r~cos\theta=(1)~cos(225^{\circ})\\\\\Rightarrow r~cos(225^{\circ})=cos(270^{\circ} - 45^{\circ})\\\\\Rightarrow r~cos(225^{\circ})t=cos(270^{\circ}) cos(45^{\circ})+sin(270^{\circ}) sin(45^{\circ})\\\\\Rightarrow r~cos(225^{\circ})=0+(-1)(\frac{1}{\sqrt{2} } )\\\\\Rightarrow r~cos(225^{\circ})=\bold{\frac{-1}{\sqrt{2} }}\\\\\Rightarrow r~cos(225^{\circ})=\bold{-\frac{\sqrt{2} }{2} }[/tex]

Now we find the second coordinate of the point.

[tex]r~sin\theta=(1)~sin(225^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=sin(270^{\circ} - 45^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=sin(270^{\circ}) cos(45^{\circ})-cos(270^{\circ}) sin(45^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=(-1)(\frac{1}{\sqrt{2} } )-0\\\\\Rightarrow r~sin(225^{\circ})=\bold{\frac{-1}{\sqrt{2} }}\\\\\Rightarrow r~sin(225^{\circ})=\bold{-\frac{\sqrt{2} }{2} }[/tex]

Therefore, the coordinates of the point on the unit circle are [tex](-\frac{\sqrt{2} }{2}, -\frac{\sqrt{2} }{2})[/tex]

Answer: 24 in.²

Step-by-step explanation: Since the base of the triangle has a length of 8 inches and the height of the triangle has a length of 6 inches, the area of the triangle is 1/2(8)(6) or 1/2(48) which is 24.

So the area of this triangle is 24 in².

Answer:

24 in^2

Step-by-step explanation:

Plug known values into the equation for triangle area: [tex]A=\frac{bh}{2}[/tex] and solve.

Another way to think of this is to multiply the base value and height value together (which is how you get area of a rectangle) and divide by two because triangles are essentially rectangles cut in half.

D. direct variation

Step-by-step explanation:

Answer:

yes it is direct variation

Step-by-step explanation:

well I'm sorry I Don't know if it's going to be step by step but my own understanding is that what ever happens on one side will affect the other side so if there is an increase in A there will be an increase in B so there's a form of equilibrium. so let's say we throw two stones A and B into a fast flowing river we expect that the water will flow so the more the velocity of the river the faster the stone will flow so as the river is flowing the stone is floating as well but an indirect variation as the river increases it's velocity the stone decreases it's movement so in direct variation as the river increases it's velocity the stone does as well. I hope this is well detailed and I answered your question , thank you

Answer:

The inequality is [tex]5.5n \leq 45[/tex]

Step-by-step explanation:

Total time:

The total time to complete the test is the sum of the number of multiple-choice questions multiplied by the time it takes to solve each and the number of short-answer questions multiply by the time it takes to solve each.

In this question:

Same number(n) of both.

Multiple-choice takes 2 minutes, short-answer takes 3.5 minutes. The total time is given by:

[tex]T = 2n + 3.5n = 5.5n[/tex]

Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.?

This means that:

[tex]T \leq 45[/tex]

So

[tex]5.5n \leq 45[/tex]

The inequality is [tex]5.5n \leq 45[/tex]

Answer:

only one solution. as the lines only intersect once

Answer:

One solution

Step-by-step explanation:

This system of equations has only one solution because the lines graphed will only intersect once.

Answer:

u=−x2−x+1

Step-by-step explanation:

Let's solve for u.

2x−u−1x^2−3x+3=2

Step 1: Add x^2 to both sides.

−x2−u−x+3+x2=2+x2

−u−x+3=x2+2

Step 2: Add x to both sides.

−u−x+3+x=x2+2+x

−u+3=x2+x+2

Step 3: Add -3 to both sides.

−u+3+−3=x2+x+2+−3

−u=x2+x−1

Step 4: Divide both sides by -1.

−u/−1=x2+x−1

−1/u=−x2−x+1

Answer:

u=−x2−x+1

Answer:

A factor is a number that when its multiplied with another number, gives a product of a given number. Example: The factors of 21 are 7,3,1 and 21. A multiple is a number that can be divided by another number a certain amount of times evenly (without a remainder). Example: Some multiples of 4 are: 8, 12, 16, and 20.

Answer:

Option C

Step-by-step explanation:

System of equations have been given as,

y - 4x = 16

y = 4x + 16 ------(1)

By comparing with slope-intercept form of the linear equation,

y = mx + b

Here, m = slope of the line

b = y-intercept

Therefore, m₁ = 4

2y = 8x + 16

y = 4x + 8 -------(2)

Slope of the line m₂ = 4

m₁ = m₂

Therefore, both the lines are parallel and both will not intersect each other.

Hence, there will be no solution of the system of equations.

Option C will be the correct option.
