The current flow to a transformer's primary circuit measures 16 amps. The transsformer's secondary current measures 80 amps. What the transformer's turns ratio?
Answer:
1/5
Step-by-step explanation:
The transformer formula is as expressed as
Ns/Np= Ip/Is
Ns and Np are the number of turns in the secondary and primary coil respectively
is and Ip are the currents in the secondary and primary coil respectively
Given the following
Ip = 16A
Is = 80A
Substitute into the formula
Ns/Np = 16/80
Ns/Np = 1/5
Hence the transformer's turn ratio is 1/5
Answer: for pf, 1:5 is WRONG!

Step-by-step explanation:
The plastic cylinder has a diameter of 2 cm. There is a rectangular 0.6 cm square prism through the middle of the cylinder, extending from the top to the bottom. The height of the cylinder is 6 cm. Find the volume of the cylinder without the prism.
Answer:
16.69 cm³
Step-by-step explanation:
In finding the volume of the cylinder without the prism you find the volume of the cylinder assuming it has no prism in it then minus the volume of the prism
Volume of the cylinder assuming there is no prism through it
V=πr²h where r is radius of the cylinder and h is height of the cylinder
Given that diameter = 2, then r= 1 cm and height, h = 6cm
V= π * 1 * 1 * 6
V= 18.85 cm³
Volume of the rectangular prism
V= l*w*h
V= 6*0.6*0.6
V= 2.16 cm³
The volume of the cylinder without the prism
18.85 cm³-2.16 cm³ = 16.69 cm³

Kelly typed a 36 word paragraph is 2/3 minute what is his typing speed in words per minute?
Answer:
His typing speed is 24 wpm. (Words Per Minute).
Step-by-step explanation:
The first thing you would have to do is convert 2/3 into a decimal, so 2/3 converted into a decimal is 0.66666666666667, then you would take that number, and multiply that by 36, the you would get you answer of 24. So, Kelly's typing speed is 24 wpm. (words per minute).
Given that

THE CORRECT ANSWER WILL BE BRAINLIEST
Answer:
x=4.8
Step-by-step explanation:
5x:9 = 8:3
It can also be written as
5x/9 = 8/3
Cross multiply
5x*3 = 8*9
15x = 72
Divide both sides by 15
15x/15 = 72/15
x =4.8

Solve for the value of x
-3x - 8 = -20
A. 4
B. 28/3
C. -28/3
D.-4|
Answer:
A. 4, X = 4
Step-by-step explanation:
-3x - 8 = -20
Move the constant to the right-hand side and change its sign
-3x = -20 + 8
Calculate the sum
-3x + -12
Divide both sides of the equation by -3
x = 4
Solution
x = 4
Is quadrilateral UVWX a parallelogram? Why or why not?
Answer:
C
Step-by-step explanation:
Slope of UV = 0 = Slope of XW
So UV is parallel to XW.
Slope of UX = [6-(-4)]/[-7-(-3)] = -5/2
Slope of VW = [6-(-4)]/(0-4) = -5/2
Slope of UX = Slope of VW i.e. UX is parallel to VW.
It is a parallelogram because opposite sides are parallel.
Answer:
Yes, because opposite sides are parallel.

Given:
In a right angle triangle,
Perpendicular = 8 units
Base = x units
Hypotenuse = 17 units
To find:
The exact value of x.
Solution:
The given triangles is a right angle triangle. So, side lengths form a Pythagorean triplet.
[tex](Hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]
[tex](17)^2=(x)^2+(8)^2[/tex]
[tex]289=x^2+64[/tex]
[tex]289-64=x^2[/tex]
[tex]225=x^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{225}=x[/tex]
[tex]\pm 15=x[/tex]
Side cannot be negative. So, [tex]x=15[/tex].
Therefore, the required value is [tex]x=15[/tex] and yes, the side lengths form a Pythagorean triplet, i.e., (8,15,17).
What is the distance from C to D?
A. 5 units
B. 1 unit
C. 25 units
D. 7 units
Answer:
Option A
Step-by-step explanation:
According to the distance formula , for any 2 points P & Q whose coordinates are (x¹ , y¹) and (x² , y²) respectively. So ,
[tex]PQ = \sqrt{(x^{2} - x^{1} )^{2} + (y^{2} - y^{1})^{2} }[/tex]
NOTE = HERE x² , y² DOESN'T MEAN THE SQUARES OF x & y . THEY ARE JUST COORDINATES.
According to the question ,
Coordinate of C = (2 , -1)
Coordinate of D = (5 , 3)
Using distance formula ,
[tex]CD = \sqrt{(5-2)^{2} + (3 -(-1))^{2} }[/tex]
[tex]=> CD = \sqrt{3^{2} + 4^{2} } = \sqrt{9 + 16} = \sqrt{25} = 5[/tex]

Step-by-step explanation:
sophie buy a guitar during the sale if the original price was $90.64 how much does sophie pay
Answer:
$67.98
Step-by-step explanation:
The discount was 25%, so you would need to multiply 90.64 and 0.25.
90.64*0.25= 22.66
However, that isn't your final answer because 22.66 is how much Sophie saved.
90.64-22.66= 67.98
Therefore, your answer would be $67.98.
Hope this helps :)

Write an equivalent expression using the Distributive Property.
Enter the correct answers in the boxes.
35+21=7(_+_)
Answer:
35 + 21 = 7(5 + 3)
Step-by-step explanation:
In this question, we have to write an equivalent expression to the one on the left, while using the distributive property.
Our equation is: 35 + 21 = 7(_ + _), we have to find the missing values.
In the equation, we can see that 7 is divisible to 35 and 21, which means we can simply divide in order to get our missing numbers.
Divide:
35/7 = 5
21/7 = 3
When we plug those values into our equation, it would be:
35 + 21 = 7(5 + 3)
When you use distributive property by distributing the 7 to the number inside the parenthesis, you would get this:
35 + 21 = 35 + 21
When you simplify, you would get the same answer.
56 = 56.
Therefore, your answer would be 35 + 21 = 7(5 + 3)
Answer:35 + 21 = 7(5 + 3) is the answer.

Sally has a budget for school stationery of $37, but has already spent $22.72 on books and folders. Let p represent the amount that Sally can spend on other stationery. Write an inequality that shows how much she can spend on other stationery, and solve for p.
Answer:
[tex]p\le 14.28[/tex]
Step-by-step explanation:
Total budget for school stationery = $37
She has already spent $22.72 on books and folders.
Left amount = $37 - $22.72
= $14.28
Let p represent the amount that Sally can spend on other stationery. It implies that "p" must be less than or equal to $14.28 .
Hence, the required inequality is :
[tex]p\le 14.28[/tex]
