35 divided by 2.5 is 14, so she biked 14 miles in 1 hour. So 14*3= 42

She can bike 42 miles in 3 hours.

40 - 4 equals 36 divided by three equals 12
12 times 3 + 4 = 40
50- 2 = 48 divided by 4 = 12
12 times 4 + 2 = 50

The potential in a region between x = 0 and x = 6.00 m is V = a + bx, where a = 15.4 V and b = -5.10 V/m.
Minchanka [31]

Answer:

V(0)=15.4\\V(3)=0.1\\V(6)=-15.2

Step-by-step explanation:

The potential in a region between x = 0 and x = 6.00 m is V = a + bx.

Put a = 15.4 V and b = -5.10 V/m.

So, V=15.4-5.10x

To find: Potential at x =0, 3, 6

Solution:

Potential at x = 0:

V=15.4-0=15.4

Potential at x = 3:

V=15.4-5.10(3)=15.4-15.3=0.1

Potential at x = 6:

V=15.4-5.10(6)=15.4-30.60=-15.2

Therefore,

V(0)=15.4\\V(3)=0.1\\V(6)=-15.2

Answer:

<h2>               XN = 6</h2>

Step-by-step explanation:

If XY is bisector of angle AXN then:   \dfrac{YN}{AY}=\dfrac{XN}{AX}

\dfrac4{12}=\dfrac{XN}{18}\\\\XN=\dfrac4{12}\cdot18\\\\XN=6

Tanya spent 1/5 of her allowance on candy and 2/3 on food. What fraction of her allowance did Tanya spend on food and candy alto
kari74 [83]
13/15 of her allowance was spent in total.

To solve this, you'd need to find the least common denominator (LCD) so that both fractions have the same number on the bottom. In this case, the first number that you could get with 5 and 3 was 15.

Next, you'd have to multiply the numerator by the same amount as the denominator, so that the fractions are proportionate. So, for 1/5, since we had to multiply 5 by 3 to get 15, we'd multiply 1 by 3 as well, giving us 3/15. Doing the same with 2/3, we'd get 10/15.

Then, you add the two fractions together (10/15 + 3/15 = 13/15).

Now, in any other case, you could probably simplify the fraction after you've solved the problem. If we got 12/15 instead of 13/15, then we could simplify that to 4/5, since both 12 and 15 are divisible by 3. But in this case, this is the simplest form of that fraction.

Hope this helped!!!
