Answer: 5 yards

Step-by-step explanation:

1. Look at the vertical parts of the drawing from right to left

2. Notice that the longest vertical part is 11 yards

3. Notice that the other labels vertical part is 6 yards

4. Notice that the third vertical part, the one with the ? is 11 yds - 6 yds since the two shorter vertical parts would make a line as long as the longest vertical part of they were put together. Since this is the case the missing part is 11 yds-6 yds = 5 yds.

Answer:

I think its C

Step-by-step explanation:

The correct answer is A

Explanation:

An orthographic drawing shows a three-dimensional figure from different perspectives or sides. Indeed, the orthographic drawing in the question shows how the object looks if you see this the front, side, and top of this. This implies the foundation drawing needs to match the figures of the orthographic drawing.

According to this, the correct figure is A because this is the only one that has a rectangle shape, and due to this, if you look at this from any different sides you will always see a rectangle. For example, the top view shows a rectangle of approximately 2x3 squares, and this view only fits with option A because B and C are not complete rectangles and therefore their top view is not a rectangle.

The term that should be added to the expression to make the expression perfect square trinomial is 169/4. The expression then becomes : (y - 13/2)²

What is meant by a perfect square trinomial?

By multiplying a binomial by another binomial, perfect square trinomials—algebraic equations with three terms—are created. A number can be multiplied by itself to produce a perfect square. Algebraic expressions known as binomials are made up of simply two words, each of which is separated by either a positive (+) or a negative (-) sign. Similar to polynomials, trinomials are three-term algebraic expressions.

A perfect square trinomial expression can be created by taking the binomial equation's square. If and only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is said to be a perfect square.

Given expression y² - 13y + ?

Comparing with the general equation

a = 1

b = -13

For perfect square trinomial

b² = 4ac

(-13)² = 4 * 1 * c

169 = 4c

c = 169/4

So the expression becomes,

y² - 13y + 169/4 = (y - 13/2)²

Therefore the term that should be added to the expression to make the expression perfect square trinomial is 169/4.

Step-by-step explanation:

1. Adding the numbers of those who study a given subject counts ...

That total is 40 +48 +44 = 132. When we subtract from this the total number of students, we get 132 -80 = 52, the number who study exactly 2 subjects plus twice the number who study all three.

From this, we can subtract the number who study exactly 2 subjects, leaving twice the number who study all three. 52 -32 = 20. So, 10 students study all three subjects.

__

2. Adding the numbers of those who study physics and another subject, we have 20+24 = 44. Subtracting twice the number who study all three gives the total of those how study only two subjects, one of which is physics. That total is 44 -20 = 24. So, of those 32 who study exactly two subjects, the remaining 32 -24 = 8 must be students who study only math and chemistry.

_____

It may be helpful to see the matrix of equations the problem statement describes. If we use the variables m, p, c, mp, mc, pc, mpc in that order to represent numbers of 1-subject, 2-subject, and 3-subject students, the augmented matrix looks like this.

Ella has 2/5 gallons of lemonade left. The value of n is (2/5) gallon for the given equation.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

To determine the amount of lemonade Ella has left after drinking 1/5 gallon for lunch, we can subtract the amount she drank from the original amount she had:

Amount of lemonade left = (3/5) gallon - (1/5) gallon = (2/5) gallon

Therefore, Ella has 2/5 gallons of lemonade left.

We could also write an equation to solve for n, the amount of lemonade that is left:

n = (3/5) gallon - (1/5) gallon

Simplifying the right-hand side:

n = (2/5) gallon

Thus, Ella has 2/5 gallons of lemonade left.

As per the given perimeter of the rectangular area, the maximum area without fencing is 788544 square feet.

Perimeter of rectangle

Perimeter of the rectangle is defined as the total length or distance around the boundary of a rectangle.

And the formula that is used to measure the perimeter of the rectangle is

P = L x B

Where

L refers the length

B refers the breadth

Given,

A farmer has 1776 feet of fencing available to enclose a rectangular area bordering a river.

Here we need to find if  no fencing is required along the river, then what will be the dimensions of the fenced area that will maximize the area.

Let us consider L and W be the length and width of the rectangular respectively.

And also, let the river run along L.

So, the perimeter to be covered by fence is written as,

=> P = L + 2W.

Therefore, when we apply the value of perimeter in it, then we get,

=> 1776 =L + 2W

Here we need the value of L, so, the equation is rewritten as,

=> L = 1776 - 2W

Now, we have to apply these value on the area formula, then we get,

A = (1776-2W) x W

When we simplify it, then we get,

=> A = 2700W-2W²

This is in the form of quadratic equation.

So, let us assume that the vertex of the rectangular at maximum area will give maximum width.

Then it can be obtained as, (W,A),

where the value of

W = -b/2a

Here the value of b = 1776 and a = -2

By applying these values on the formula, then we get the value of W as,

=> W = -1776/2*(-2)

=> W = -1776/-4

=> W = 444ft.

Therefore, the length is

=> L = 1776 - 2(444)

=> L = 1776 - 888

=> L = 888

Maximum area, A=888*888 = 788544 square feet.

The monthly costs of each plan as functions of the number of movies watched:

A(x) = 22 + x

To graph these functions, we can plot several points for each one, as shown in follow fig.

A(x) - B(x) < 0

(22 + x) - (14 + 3x) < 0

22 + x - 14 - 3x < 0

Rounding to the nearest liter, the volume of the liquid in the pipe is approximately 0.01 liters. Therefore, none of the options A, B, C, or D provided is the correct answer.

To calculate the volume of the liquid in the cylindrical steel pipe, we need to find the difference in volume between the solid cylinder (hollow part) and the hollow cylinder.

Given:

Length of the cylindrical steel pipe (hollow part) = 21 cm

Radius of the solid cylinder = 0.4 cm

Radius of the hollow cylinder = 0.1 cm

First, let's calculate the volume of the solid cylinder (hollow part):

V1 = π × \(r1^2\) × h

V1 = π × \((0.4 cm)^2\) × 21 cm

Next, let's calculate the volume of the hollow cylinder:

V2 = π × \(r2^2\) × h

V2 = π × \((0.1 cm)^2\) × 21 cm

Now, we can find the volume of the liquid in the pipe by subtracting V2 from V1:

Volume of liquid = V1 - V2

Let's calculate these values:

V1 = π ×\((0.4 cm)^2\) × 21 cm ≈ 10.572 cm³

V2 = π × \((0.1 cm)^2\) × 21 cm ≈ 0.693 cm³

Volume of liquid = V1 - V2 ≈ 10.572 cm³ - 0.693 cm³ ≈ 9.879 cm³

To convert the volume from cubic centimeters (cm³) to liters (L), we divide by 1000:

Volume of liquid in liters ≈ 9.879 cm³ / 1000 ≈ 0.009879 L

Rounding to the nearest liter, the volume of the liquid in the pipe is approximately 0.01 liters.

Therefore, none of the options A, B, C, or D provided is the correct answer.
