A solenoid has a magnetic field of magnitude 0.50T when carrying a current of 400 A. The solenoid is 8.0 m long. What is the number of turns in this solenoid, assuming that it is an ideal solenoid?
Answer:
The correct answer is "995.22 turns".
Step-by-step explanation:
The given values are:
Magnetic field,
B = 0.50 T
Current,
i = 400 A
Length of solenoid,
L = 8.0 m
As we know,
⇒ [tex]B=\mu_0ni[/tex]
then,
⇒ [tex]n=\frac{B}{\mu_0i}[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{0.50}{4 \pi\times 10^{-7}\times 400}[/tex]
⇒ [tex]=\frac{0.50}{5.024\times 10^{-4}}[/tex]
⇒ [tex]=995.22 \ turns[/tex]

THERE ARE 7 CONSECUTIVE NUMBERS.
IF THE LARGEST NUMBER 15 99, WHAT
IS THE SUM OF ALL THE GIVEN NUMBENS.
Answer:
S₇ = 672
Step-by-step explanation:
If there are 7 consecutive numbers and the largest is 99, then there are 6 smaller consecutive numbers:
Smallest number = 99-6 = 93
The sequence is 93, 94, 95, 96, 97, 98, 99.
Where:
a₁ = 93
an = 99
n = 7
Sum of the sequence:
Sn = n/2(a₁ + an)
S₇ = 7/2 (93 + 99)
S₇ = 7/2 (192)
S₇ = 7(96)
S₇ = 672
Greta currently works 45 hours per week and earns a weekly salary of $729. She
will soon be starting a new job where her salary will be increased by 10% and her
hours reduced by 10%.
How much more will she be earning per hour at her new job?
Answer:
Step-by-step explanation:
current rate = $729/(45 hours) = $16.20/hour
increased salary = 1.10×$729 = $801.90
decreased hours = 0.90×45 = 40.5
increased rate = $801.90/(40.5 hours) = $19.80/hour
increase in rate = $19.80/hour - $16.20/hour = $3.60/hour

Answer:
Equation: y = 2x
Graph: see attachment
Step-by-step explanation:
Pieces of paper = x
Number of Valentines = y
The equation is a proportional equation and can be represented as y = kx
k is the constant of proportionality
k = y/x
Using (2, 4),
k = 4/2 = 2
To find the equation, substitute k = 2 into y = kx
Thus:
y = 2x

A garden has an area of 24 square feet. The garden is 2 feet longer than
it is wide. What is the width of the garden?
w = 4.8 feet
w = 4 feet
W = 8 feet
w = 3 feet
Answer:
w = 4ft
Step-by-step explanation:
b × w = a
(w + 2)(w) = 24
Simplify.
w² + 2w = 24
Solve
w = 4
Double check.
4 × 6 = 24

Equivalent expression of 10+(x divided 16)
Answer:
x/16 + 10
Step-by-step explanation:
10+(x÷16)
To add or subtract expressions, expand them to make their denominators the same. Multiply 10 times 16/16.
10 x 16 / 16 + x/16
Since 10 x 16 / 16 and x/16 have the same denominator, add them by adding their numerators.
10 x 16 + x / 16
Do the multiplications in 10×16+x.
160 + x / 16 = x/16 + 10

1. Determine the intervals for which the function shown is:(not multiple choice)
a. increasing
b. decreasing
c. constant.
Fully explain the basis for each answer
9514 1404 393
Answer:
a) (-1, 2)
b) (-4, -1)
c) (2, 5)
Step-by-step explanation:
a) "Increasing" means points to the right are higher. This is the case for points in the interval from x = -1 to x = 2. In interval notation, the function is increasing in (-1, 2).
__
b) "Decreasing" means points to the right are lower. This is the case for points in the interval from x = -4 to x = -1. In interval notation, the function is decreasing in (-4, -1).
__
c) "Constant" means points to the right have the same value. This is the case for points in the interval from x = 2 to x = 5 (or higher). In interval notation, the function is constant in (2, 5).
Dear Mate,
your answer is
a = (-1, 2 )
b = (-4 , -1 )

- 6 + \sqrt{9 - 8a} = 1−6+
9−8a
=1
Answer:
[tex]a = -5[/tex]
Step-by-step explanation:
Given
[tex]- 6 + \sqrt{9 - 8a} = 1[/tex]
Required
Solve for a
[tex]- 6 + \sqrt{9 - 8a} = 1[/tex]
Add 6 to both sides
[tex]6- 6 + \sqrt{9 - 8a} = 1+6[/tex]
[tex]\sqrt{9 - 8a} = 7[/tex]
Square both sides
[tex]( \sqrt{9 - 8a})^2 = 7^2[/tex]
[tex]9 - 8a = 49[/tex]
Subtract 9 from both sides
[tex]9-9 - 8a = 49-9[/tex]
[tex]- 8a = 40[/tex]
Make a the subject
[tex]a = -\frac{40}{8}[/tex]
[tex]a = -5[/tex]
a. Renard let’s t= the number of taffy bags and c= the number of Carmel bags. Help him write two equations to represent the information in the problem.
b. Now are are is stuck. He says, “if both of the equations were in the form ‘t= something’, I could set the two expressions equal to each other to find the solution.” Help him rewrite the equations into a form he can use to solve the problem.
c. Solve Renard’s system of equations to find the number of bags of Carmel and number of bags of taffy that Ariel bought.
d. How you can verify that your solution is correct?
Answer:
20 taffy bags and 15 caramel candy bagsStep-by-step explanation:
Given:
t = the number of taffy bagsc = the number of caramel bagsNumber of taffy's are 5 more than caramel bagsTaffy bags weigh 8 ounces and caramel bags weigh 16 ouncesTotal weight is 400 ouncesEquations:
t = c + 5 (the difference in number of bags)8t + 16c = 400 (the weight of the bags)Simplify the second equation by dividing all terms by 8:
t + 2c = 50Substitute t and solve for c:
c + 5 + 2c = 503c = 50 - 53c = 45c = 45/3c = 15Find the value of t:
t = 15 + 5 = 20Answer:
