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]

Refer to the Exhibit Student Grades. The professor has informed the class that 7.93 percent of her students received grades of A. What is the minimum score needed to receive a grade of A
This question is incomplete, the complete question is;
Refer to the Exhibit Student Grades. A professor at a local university noted that the grades of her students were normally distributed with a mean of 73 and a standard deviation of 11.
The professor has informed the class that 7.93 percent of her students received grades of A. What is the minimum score needed to receive a grade of A
Answer:
the minimum score needed to receive a grade of A is 88.51
Step-by-step explanation:
Given the data in the question;
Let x represent the grades of the students that were normally distributed with mean μ = 73 and standard deviation σ = 11.
so, The professor has informed the class that 7.93 percent of her students received grades of A
the minimum score needed to receive a grade of A will be:
P( X > x ) = 7.93 %
P( X > x ) = 0.0793
1 - P( X ≤ x ) = 0.0793
- P( X ≤ x ) = 0.0793 - 1
- P( X ≤ x ) = - 0.9207
P( X ≤ x ) = 0.9207
⇒ P( X-μ/σ ≤ x-μ/σ ) = 0.9207
so, x-μ/σ = InvNormal( 0.9207 )
x-μ/σ = 1.41
(x - 73) / 11 = 1.41
(x - 73) = 1.41 × 11
(x - 73) = 15.51
x = 15.51 + 73
x = 88.51
Therefore, the minimum score needed to receive a grade of A is 88.51

What was the total cost of the taxicab ride with tip?
Enter your answer in the box.
Answer:
Step-by-step explanation:
1. Find 15% of $33 to find the tip.
Find 1% of $33 (move the decimal over 2 places to the left. $0.33
2. Multiply the 1% tip by 15%
33 * 15 = $4.95
3. Add $33 and $4.95
4.95 + 33.00 = $37.95 total

x=60° because if 150°=90°+60° so a line is 180° consequently
90°+30°+x=180°
120°+x°= 180°
x°= 180°-120°= 60°

Calculate the state income tax owed on a $90,000
per year salary.
tax = $[?]
Answer:
$4918
Step-by-step explanation:
first income must be divided according to tax bracket
2% tax on first 3000 income= 2% of $3000=$60
3% tax on income after first 3000 but upto 5000= 5000-3000= $2000
=3% of 2000= $60
5% tax on income after second 5000 but upto 12000= 17000-5000
=12000 5% of $12000= $600
Lastly, 5.75% income over 17000=
90000-17000= $73000 so, 5.75 % of 73000= $4197.5
tax= $60+60+600+4197.5
= $4917.5
= $4918

1.) tan(28) = x/8
8*tan(28) = x
x = 4.25
2.) tan(28) = 8/x
8/tan(28) = x
x = 15
3.) tan(x) = 4/5
x = arctan(4/5)
x = 38.7°

Priya’s family exchanged 250 dollars for 4,250 pesos. Priya bought a sweater for 510 pesos. How many dollars did the sweater cost?
Answer:
The sweater cost 30 dollars.
Step-by-step explanation:
Set up a proportion
x/510 = 250/4250 Multiply both sides by 510
x = 250 * 510/4250 multiply 250 * 510
x = 127500 / 4250 Divide by 4250
x = 30
try filling out the table.
4250 250 dollars
425 25 dollars
425/25 1 dollar
17 1 dollar
17*3 3 dollars
51 3 dollars
51*10 30 dollars
510 30 dollars.
