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.

Help please!!! Find x and Y
Answer:
x = 40
y = 15
Step-by-step explanation:
Given is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60°.
Therefore,
(x + 20)° = 60°
x + 20 = 60
x = 60 - 20
x = 40
4y = 60
y = 60/4
y = 15

Someone pls also include any work if they can thank you! I’ll mark brainliest!
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)

Write the equation for a vertical line going through the point
(-4,1)
Answer:
x = -4
Step-by-step explanation:
a vertical line means it will cross only the x-axis, not the y-axis
wherever it cross the axis, that will be the point in your equation

16x-8-14x=10 show work
Answer:
x=9
Step-by-step explanation:
Original equation: 16x-8-14x=10
Combine like terms: 2x-8=10
Add 8 to both sides: 2x=18
Divide by 2 on both sides: x=9
Let me know if this helps!
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
2x=18/2
x=9
eggs are packaged by the dozen. if a dozen eggs cost $1.20, what is the unit price per egg?
Answer:
$0.10
Step-by-step explanation:
$1.20 divided by 12
Answer:
Price divided by quantity
that equation will make unit price a heck of a lot easier to remember
in this case, the quantity is 12. The price is 1.20. So, divide 1.20 by 12, and you get 10 cents per egg.
The unit price is .10 cents per egg.
Ally picked 25 roses. She gave away 10 roses. What percent of the roses does Ally still have?
Answer:
She still has 60%
Step-by-step explanation:
First you make the 25 a 100 which is basically multiply by 4 which you should do the same for 10
so 40/100 is how much she game away
She gave away 40%
She still has 60%
The percent of the roses does Ally still have is 60%.
Given that,
Ally picked 25 roses. She gave away 10 roses.
Based on the above information, the calculation is as follows:
[tex]= \frac{25-10}{25}[/tex]
= 60%

Step-by-step explanation:
First find the value of Y=> 5y-8=3y+1
=> 5y-3y=1+8
=> 2y=9
=> y=4.5
Second find the value of X=> x+6=4x
=> 6=4x-x
=> 6=3x
=> x=(6/3)
=> x=2
Thus, x=2 and y=4.5 [Option C]

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

Option (4) is correct.
What is Inequality?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.
