Hey there, since we already have common denominators (the common denominators are 12) we are going to keep the denominator the same and add the numerators, 6+6=12. So, we have 12/12. And you asked to simplify it so 12/12=1. Therefore, 6/12+6/12=1. Hoped I helped. :)

Its 1 whole because if u add the numerator 6+6 its 12 and the denominator dtays the same so it would be 12/12 which equals 1

What is the surface area of the triangular prism?<br><br> I need answer ASAP
Nezavi [6.7K]

Answer: 81 ft^2

Hello! The surface area of the rectangular prism will follow this process:

Right triangle area: (1/2)bh

So that 6ft (4.5ft) = 27ft^2/2; though when one multiplies that by 2 (as there are two right triangles), we get a surface area of 27ft^2.

For the rectangle's area, it's slightly more deviated since each face is different in length: bh

Face 1 = 3ft(7.5ft) = 22.5ft^2

Face 2 = 3ft(6ft) = 18ft^2

Face 3 = 4.5ft(3ft) = 13.5 ft^2

Thus, if we add these all together (27ft^2. + 22.5ft^2 + 18ft^2 + 13.5 ft^2), we get 81 ft^2

Survey data indicate that 42% of customers at Mega Hit video rental stores subscribe to premium movie channels through their cab
omeli [17]

Answer:

P=0.17

Step-by-step explanation:

If A and B are dependent events, then we have a Rule of Addition:

P(A\cup B)=P(A)+P(B)-P(A\cap B)

Let A represent event that customer at Mega Hit is subscribed to premium movie channels while B represent event that customer at Mega Hit owns a DVD, so, we get the following:

P(A)=0.42\\P(B)=0.31\\P(A \cup B)=0.56\\\\

We need to find P(A \cap B) or probability that a randomly selected Mega Hit customer both owns a DVD and subscribes to a premium movie channels.

Using Rule of Addition, we get:

0.56=0.42+0.31-P(A \cap B)\\\\0.56=0.73-P(A\cap B)\\P(A\cap B)=0.73-0.56\\P(A\cap B)=0.17

So, the required probability is 0.17.

IRISSAK [1]

Answer:

x = 10

Step-by-step explanation:

In the last step, you can see that the fraction \frac{1}{5} has been multiplied by its reciprocal \frac{5}{1}, making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply \frac{6}{3} · \frac{5}{1} :

6 · 5 = 30

3 · 1 = 3

<u><em>So now you should have the fraction:</em></u>

x = \frac{30}{3}

<u><em>But, you can still simplify the fraction by dividing 30 by 3:</em></u>

x = 10

A line passes through (3, 7) and (6, 9). Which equation best represents the line? (4 points) y = 3 over 2 x + 5 y = 2 over 3 x +
kotykmax [81]

Given two points, the equation of the line may be determined by,

y - y1 = ((y2 - y1) / (x2 - x1))(x - x1)

Substituting the given values,

y - 7 = ((9 - 7) / (6 - 3))(x - 3)

Simplification will yield to an answer of,

y = 2x/3 +5

Therefore, the answer is the second choice.
