3/15 divided by 6/5

6 0

Diving by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction.

$\frac{3}{15}$ ÷ $\frac{6}{5}$ → $\frac{3}{15}$ × $\frac{5}{6}$

Now, we are multiplying fractions.

$\frac{3}{15}$ × $\frac{5}{6}$

To multiply fractions, we can multiply the numerators together and the denominators together.

3 × 5 = 15

15 × 6 = 90

15 ÷ 15 = 1

90 ÷ 15 = 6

Therefore, $\frac{3}{15}$ ÷ $\frac{6}{5}$ = $\frac{1}{6}$

Answer: 1/6

Invert 6/5 which becomes 5/6 and then multiply

3/15×5/6= 15/90

Which simplified becomes 1/6

A quadratic equation with real coefficients and leading coefficient 1, has x = -bi as a root. Write the equation in general form

andrey2020 [161]

<span>The general form of quadratic equation with real coefficients and leading coefficient 1, has x = -bi as a root
=> x = <u>-b + </u></span><u>√ b^2 – 4 ac</u><span>
2a

It is also written as:
=> ax^2 + bx + c = 0

Quadratic equation involves unknown numbers which is x, the numbers which a, b and c are called coeffecients.
There are also quadratic factorization where you factor the polynomial give to be able to get the value of the equation.</span>

Four resistors are connected in series such that their total resistance is 50ohm . If the resistance of resistors is 5 ohm , 10o

Katyanochek1 [597]

<h2>Answer:</h2>

$\boxed{R_{4}=20\Omega}$

<h2>Step-by-step explanation:</h2>

If resistors are in series, so the current $I$ is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:

$R_{eq}=R_{1}+R_{2}+R_{3}+R_{4}$

$R_{eq}$ is the total resistance $50\Omega$ . Moreover:

$R_{1}=5\Omega \\ R_{2}=10\Omega \\ R_{3}=15\Omega$

Therefore:

$50=5+10+15+R_{4} \\ \\ R_{4}=50-(5+10+15) \\ \\ R_{4}=50-30 \\ \\ \boxed{R_{4}=20\Omega}$

gallons of water can fill a pool that is 50 yards by 20 yards and is 9 feet deep? (Assume 7 1/2 gallons per cubic foot.)

saul85 [17]

L = 50 yards or 150 feet W = 20 yards or 60 feet H = 9 feet V = 150 * 60 * 9 V = 81000 cubic feet then multiply the volume, 81000, by 7.5, or 607,500 gallons.
