2/5 + k/4 = 9/10 (solve with work)

Alla [95]

The LCD of 2/5 + k/4 = 9/10 is 20. Applying this LCD, we get:

8 + 5k = 18. Subtracting 8 from both sides: 5k = 10. Then k = 10/5, or k = 2.

A video game randomly chooses your car color and type. The probability of getting a red car is 0.25, and the probability of gett

EleoNora [17]

In probability 2 events are independent if the occurrence of 1 event does not affect the occurrence of the other event. Mathematically, if event A and event B are independent, then $P(A\&B)=P(A)\times P(B)$ . For our two events in this problem we have that $P(A)=0.25$ and $P(B)=0.40$ . If these two events are independent, then we should have that,

$P(A\&B)=P(A)\times P(B)\\P(A\times B)=0.25\times 0.4=0.1.$

.A and B are independent events if the probability of A and B is 0.1

How do you rewrite 6/9 in two different ways

Naya [18.7K]

We have to represent the fraction $\frac{6}{9}$ in two different ways.

Let us multiply the numerator and denominator of the given fraction by '2'.

Therefore, $\frac{6}{9} = \frac{6 \times 2}{9 \times 2} = \frac{12}{18}$

Therefore, $\frac{12}{18}$ is the first way to represent the given fraction.

Now, Let us multiply the numerator and denominator of the given fraction by '3'.

Therefore, $\frac{6}{9} = \frac{6 \times 3}{9 \times 3} = \frac{18}{27}$

Therefore, $\frac{18}{27}$ is the second way to represent the given fraction.

Therefore, $\frac{12}{18}$ and $\frac{18}{27}$ are the different ways to represent the fraction $\frac{6}{9}$ .

What is the value of p in the question below. 10x9/2x4= px 5

ycow [4]

Answer:

p = 5

Step-by-step explanation:

We have that:

$\frac{x^{a}}{x^{b}} = x^{a-b}$

So

$\frac{x^{9}}{x^{4}} = x^{9-4} = x^{5}$

10/2 = 5

Then

$\frac{10x^{9}}{2x^{4}} = 5x^{9-4} = 5x^{5}$

Finding p:

$5x^{5} = px^{5}$

$p = \frac{5x^{5}}{x^{5}}$

$p = 5$
