Cross multiply
$49*5=35*n$
$n= \frac{49*5}{35}=7$
Please mark me as brainiest.

Answer: n=7

Step-by-step explanation:

We are given an equation : $\dfrac{35}{49}=\dfrac{5}{n}$

To find n , we multiply n on both the sides , we get

$\dfrac{35}{49}\times n=\dfrac{5}{n}\times n$

$\Rightarrow\ \dfrac{35n}{49}=5$

Now, we multiply 49 on both sides , we get

$\dfrac{35n}{49}\times49=5\times49$

$35n=245$

Divide both sides by 35, we get

$\dfrac{35n}{35}=\dfrac{245}{35}\\\\\Rightarrow\ n=7$

segment BC is an are of a circle with radius 30.0 cm, and point P is at the center of curvature of the arc Segment DA is an arc

Elan Coil [88]

Answer:

The magnetic field is $B = 3.87 *10^{-6} \ T$

Direction is inward

Step-by-step explanation:

The diagram for this question is shown on the first uploaded image

From the question we are told that

The radius of BC is $r_{BC} = 30 \ cm = 0.30 \ m$

The radius of DA is $r _{DA} = 20 \ cm = 0.20 \ m$

The length of CD is $r_{CD} = 10 cm = 0.1 \ m$

The length of AB is $r_{AB} = 10 cm = 0.1 \ m$

The current is $I = 11.4A$

The magnetic field is mathematically represented as

$B = B_{BC} + B_{DA} + B_{CD} + B_{AB}$

$B = \frac{\mu_o I}{4 \pi } [ \frac{\theta_{DA}}{r_{DA}} + \frac{\theta_{BC}}{r_{BC}}+ \frac{\theta_{CD}}{r_{CD}}+\frac{\theta_{AB}}{r_{AB}}]$

Where

$\theta_{BC} = \theta_{DA} = \frac{2\pi}{3}$

Where $\frac{2 \pi}{3} = 120^o$

$\theta_{CD} = \theta_{AB} = 0^o$

$B = \frac{\mu_o I}{4 \pi } [ \frac{\frac{2\pi}{3} }{0.20} - \frac{\frac{2\pi}{3}}{0.30}}+ \frac{0}{0.10}+\frac{0}{0.10}]$

$B = 3.87 *10^{-6} \ T$

The direction is into the page

This because the magnitude of the magnetic field due to arc BC whose direction is outward is less than that of DA whose direction is inward

This is because according to Fleming's Left Hand Rule the direction of current is perpendicular to the direction of magnetic field so since current in arc BC and DA are moving in opposite direction their magnetic field will also be moving in opposite direction

If a line falls on the points (3, 1) and (9,5), what is its slope? Enter your

Anvisha [2.4K]

<h3>Answer: 2/3</h3>

============================================================

Use the slope formula to get that answer

m = (y2-y1)/(x2-x1)

m = (5-1)/(9-3)

m = 4/6

m = 2/3

We have a rise of 2 and a run of 3.

In other words, we move up 2 and over to the right 3.

Eddie's fishing. He has 1 1/4 ounces of weights on his line, but his bait isn't getting to the bottom of the lake. Eddie add ano

mario62 [17]

The initial weight is given by:
$1 \frac{1}{4} = 1.25
$
Then, we add a second weight:
$\frac{1}{2} = 0.5
$
Finally, we add a third weight:
$\frac{3}{4} = 0.75
$
Adding the three added weights, we can find the total weight.
We have then:
$1.25 + 0.5 + 0.75 = 2.5
$
The total weight is:
$2.5 = 2 \frac{1}{2} 
$
Answer:
eddie now has $2 \frac{1}{2}$ ounces on his line
