What is the Width, explain how you got your answer (8 points btw)

Answers

Answer:

Based off of my calculations, I got 126

Step-by-step explanation:

The formula for area would be: A = L * W

So, when finding the width (W), you would need to divide the area (A) by the length (L).

Equation: W = A / L

Now you know the equation, all you need to do is plug in the numbers:

[84 divided by 2/3]

W = 84  /  2/3

After solving this, you would get: 126

So, W = 126.

To check if we got the correct answer, we could just multiply the length times the width:

126 * 2/3

Since this equation gives us 84 as the answer, 126 is the correct width.

which step is the same in the construction of a perpendicular line through a point on a line and the construction of a perpendicular line through a point off a line?

Answers

A line is said to be perpendicular to another line if the two lines intersect at a right angle. Explicitly, a first line is perpendicular to a second line if (1) the two lines meet; and (2) at the point of intersection the straight angle on one side of the first line is cut by the second line into two congruent angles.

We want to find a perpendicular line to a given line, such that it passes through a point (and we want to separate the case where the point is on the line and when the point is not in the line, we will see that the construction is exactly the same).

Well, let's define the first line:

f(x) = a×x + b

where a is the slope and b is the y-intercept.

and the point (x₁, y₁).

We know that any perpendicular line to the above one will have a slope equal to:

s = -(1/a)

So the perpendicular line will be something like:

y = -(1/a)×x + c

Now we need to find the value of c, and here we need to use the point (x₁, y₁).

If the line passes through this point, this means that when x = x₁, the value of y must be y₁.

So we can just replace these in the equation:

y₁ = -(1/a)×x₁ + c

now we can solve for c:

c = y₁ + x₁/a

Then the equation of the line is:

y = -(1/a)×x + (y₁ + x₁/a)

And as you can see, here we did not use the fact that (x₁, y₁) belongs or not to the original line, so the construction is exactly the same in both cases.

Step-by-step explanation:

Either of these would work because it must be an even number divisible by 2.

It must end in a zero : divisible by 5 but even.

It must be a multiple of 30 as 3 only goes into 10s at 30. And that takes care of the 6 too.

But 4 doesn't go into 30, so 60?….

Yes, 60 is divisible between 2, 3, 4, 5 and 6

Andre is making paper cranes decorate for a party. He plans to make one large paper crane for a centerpiece and several smaller paper cranes to put around the table. It takes Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will only have 30 minutes to make the paper cranes once he gets home.



​Andre wrote the inequality 3x + 10 ≤ 30 to plan his time. Describe what x, 3x, 10, and 30 represent in this inequality.

Answers

Answer:

Andre can make 6 small paper cranes in 30 minutes.

Step-by-step explanation:

Given data-

Time taken by Andre to build small cranes- 3minutes

Time taken to build large crane- 10 minutes

Total time allotted to him= 30 min

His preferences- Building one large crane and several small cranes.

The Inequality equation is 3​c​ + 10 ≤ 30

Since his preference is to build atleast one large crane which takes 10 minutes, he is left with 30-10 = 20 minutes to build other small cranes.

For one crane he needs, 3 minutes

Hence, he can build 6 cranes in 18 minutes. Following this, he is left with  20-18= 2 minutes. Since he needs at least 3 min to build a small crane, he cannot build a small crane in the remaining 2 min.

he builds 6 small cranes in 30 minutes

Alternatively,

3​c​ + 10 ≤ 30

Subtracting 10 from both sides

3c ≤ 20

The maximum value of c for which this equation remains valid is 6.

Thus, he builds a total of 6 cranes (small) in 30 minutes.

I hope this helps.

the sum of angles in a triangle is 180° and if we subtract 116 from that we get 64. now since the sides of the triangle are the same we need to divide 64 with 2 and we get 32

Answer:

32 degrees

Step-by-step explanation:

So, based on the side lengths, the triangle is isosceles since two of the sides are of equal length. So, in isosceles triangles the two base angles are congruent. If there are 180 degrees in a triangle, then 180-116 would be the sum of the remaining base angles in the triangle.

180-116=64

So, divide 64 by 2 since the two angles are equal and have a sum of 64

So, x would be 32 degrees
