Answer 2

Answer:

Answer:

x = 115°

Step-by-step explanation:

We know that a triangle has 180° in total when you add up all the interior angles. So in order to find the value of x°, we need to find the missing angle in the triangle itself:

180°-(75°+40°)

= 180° - 115°

= 65°

To find x°, we know that the 65° angle + x° is equal to 180° because it's a supplementary angle. So:

x° + 65° = 180°

x° = 115°

Find the product. 0.75(68)

Answers

Final answer:

To find the product of 0.75 and 68, multiply 75 by 68 to get 5100, then shift the decimal two places to the left to get the final result: 51.

Explanation:

The question is asking you to find the product of 0.75 and 68, which is a multiplication problem. To solve this, simply multiply 0.75 by 68. Here is how:

First, multiply 75 by 68, which gives you 5100.
Then, since 0.75 has two decimal places, move the decimal two places to the left in your result. This gives you 51.00 or just 51.

What is 9-4(2p-1)=45?

Answers

9 - 4(2p - 1) =45
5(2p - 1) = 45
10p - 5 = 45
10p = 45 + 5
10p = 50
p = 50/10
p =5 (ans)

9-4(2p-1)=45
5(10p-5)=45
10p-5=45
10(5)-5=45
50-5=45
45=45

Line AB contains points A (−2, 6) and B (4, 5). The slope of line AB is −6 negative 1 over 6 1 over 6 6

Answers

Answer:

The slope is negative $1$ over $6$

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

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

we have

$A(-2,6)\ B(4,5)$

Substitute the values

$m=(5-6)/(4+2)$

$m=-(1)/(6)$

To work out the slope of a line, you have to divide the difference in y by the difference in x

The difference in y = 5-6 = -1
The difference in x = 4--2 = 6

So, -1/6 is the answer

Please help! Correct answer only!Cooper and Alice made a list of 7 psychology experiments they want to try at home. Each experiment tackles one specific psychology topic. 5 of the experiments involve cats.

If Cooper and Alice randomly choose 4 experiments to try over the summer, what is the probability that all of them involve cats?

Write your answer as a decimal rounded to four decimal places.

Answers

Answer:

Probability = 0.2603

Step-by-step explanation:

Consider the steps below;

$Probability of Experiment Involving Cats - 5 / 7,\nProbability That 4 Chosen Experiments Are All Involving Cats - ( 5 / 7 )^4,\n\n5 / 7 * 5 / 7 * 5 / 7 * 5 / 7 =\n\nConclusion; Probability - 625 / 2401$

Solution; Probability = ( About ) 0.2603

A particular computer takes 11 minutes to download a 44 minute TV show. How long will it take the computer to download a 1.5 hour movie?

Answers

44/11= 4
4 minutes of the movie are downloaded each minute.
1.5 hours= 90 min
90/4= 22.5 minutes

Divide 44 by 11 which equals 4Then 1.5 is 1 hour and 30 minutes so add 60 +30 Which equals 90Then multiply 90 ×4 = 360 minutes
