The NEC permits 20% of the cross sectional area in a wireway to be occupied by conductors.for an 8"×8"×6' long wireway the conductors can occupy. In squared?

Answers

Answer 1

Answer:

Step-by-step explanation:

Sjaoa

Answer 2

The required cross-sectional area in a wireway is 12.8 In squared.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

We have been given an 8"×8"×6' long wireway the conductors can occupy.

Since the NEC permits 20% of the cross-sectional area in a wireway to be occupied by conductors

So the required cross-sectional area in a wireway is

⇒ 20 % of ( 8"×8" )

⇒ 0.20 × (64 )

⇒ 12.8 In squared

Thus, the required cross-sectional area in a wireway is 12.8 In squared.

=> 2y=9

=> y=4.5

Second find the value of X

=> x+6=4x

Answers

Answer/Step-by-step explanation:

A1. Reference angle = 41°

Hypotenuse = x

Adjacent = 7

Thus, applying trigonometric ratio, we would have:

Cos 41 = 7/x

Multiply both sides by x

x × cos 41 = 7

Divide both sides by cos 41

x = 7/cos 41

x = 9.3 (nearest tenth)

A2. Reference angle = 65°

Hypotenuse = 6

Opposite = y

Thus, applying trigonometric ratio, we would have:

Sin 65 = y/6

Multiply both sides by 6

6 × sin 65 = y

5.4 = y (nearest tenth)

y = 5.4

A3. Reference angle = 50°

Hypotenuse = z

Opposite = 8

Thus, applying trigonometric ratio, we would have:

Sin 50 = 8/z

Multiply both sides by z

z × sin 50 = 8

Divide both sides by sin 50

z = 8/sin 50

z = 10.4 (nearest tenth)

B1. Reference angle = 49°

Hypotenuse = x

Opposite = 7

Thus, applying trigonometric ratio, we would have:

Sin 49 = 7/x

Multiply both sides by x

x × sin 49 = 7

Divide both sides by sin 49

x = 7/sin 49

x = 9.3 (nearest tenth)

B2. Reference angle = 25°

Hypotenuse = 6

Adjacent = y

Thus, applying trigonometric ratio, we would have:

Cos 25 = y/6

Multiply both sides by 6

6 × cos 25 = y

y = 5.4 (nearest tenth)

B3. Reference angle = 40°

Hypotenuse = z

Adjacent = 8

Thus, applying trigonometric ratio, we would have:

Cos 40 = 8/z

Multiply both sides by z

z × cos 40 = 8

Divide both sides by cos 40

z = 8/cos 40

z = 10.4 (nearest tenth)

Combine like terms: 2x-8=10

Add 8 to both sides: 2x=18

Divide by 2 on both sides: x=9

Answer:

x=9

Step-by-step explanation:

16x-8-14x=10

16x+-8+-14x=10

(16x+-14x)+(-8)=10 ( Combine like terms)

2x-8=10

Add 8 to both sides

2x-8=10

+8 +8

2x=18

Divide both sides by 2

In ΔRST, r = 52 cm, s = 55 cm and ∠T=48°. Find the length of t, to the nearest centimeter.

Answers

Answer:

44

Step-by-step explanation:

delta math

The length of t is approximately 43.60 cm, to the nearest centimeter.

What are the properties of Triangle?

The properties of the triangle are:

1. The sum of all the angles of a triangle (of all types) is equal to 180°.

2. The sum of the length of the two sides of a triangle is greater than the length of the third side.

3. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

To find the length of side t in triangle RST, we can use the law of cosines, which relates the lengths of the sides and the cosine of one of the angles in a triangle:

[tex]c^2 = a^2 + b^2 - 2ab cos(C)[/tex]

where c is the length of the side opposite the angle C, and a and b are the lengths of the other two sides.

In this case, we know that:

r = RS = 52 cm

s = ST = 55 cm

∠T = 48°

So, we want to find the length of t, which is the side opposite the angle T.

Let's call the length of t "c". Then, applying the law of cosines, we have:

[tex]c^2 = r^2 + s^2 - 2rs cos(T)\\\\c^2 = (52 cm)^2 + (55 cm)^2 - 2(52 cm)(55 cm) cos(48^0)\\\\c^2 = 1901.57[/tex]

Taking the square root of both sides, we get:

c= 43.60 cm

Therefore, the length of t is approximately 43.60 cm, to the nearest centimeter.

Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality.

As per the given diagram:

A line is drawn and a certain range of values are marked on the line,

To find the compound inequality that could be represented by the graph.

Because a number line with only real numbers is displayed in the provided graph.

We identify the solution set for each option by considering it separately.

1) -4 ≤ x ≤ 4

Since, the solution set contain only numbers between -4 and 4.

So it is false.

2) -2 ≤ x ≤ -1

This is a wrong representation.

3) x ≤ -1 or x ≥ 0

This represents all real numbers, excluding numbers between -1 and 0

So it is false.

4) x ≤ 3 or x ≥ -1

So it represents all the real numbers on number lines as shown in the graph below.

So, it is true.

x ≤ 3 or x ≥ -1 represent the given graph.
