Find The Value Of X.

Answers

Answer 1

Answer:

45 degrees

Step-by-step explanation:

Before we start, it is important to know that the sum of all angles of a triangle adds up to 180. Since one of the angle measure is already given to us, 90, we can subtract this from 180.

180-90=90

This tells us that the two remaining angles will add together to equal 90. In addition, it also tells us that the two remaining angles are equal. This means we can divide 90 by 2, and it leaves us that x= 45 degrees.

Answer 2
the angles inside a triangle = 180°.

You can see that this is a right triangle so one of the angles equals 90°. 180-90= 90°.

Now we can see the remaining two angles add up to 2x. So if we put all our work together 2x= 45°.
Divide both sides by 2 to get x alone

And we come to that x equals 22.5.

x= 22.5°

Brian rolls a fair dice 12 times. How many times would Brian expect to roll a number greater than 4?

Answers

Brian is expected to roll a number greater than 4, 4 times

How to determine the expected row?

In a fair die, we have:

Faces = 6

Faces greater than 4 = 2 i.e. 5 and 6

So, the probability to roll a number greater than 4 is:

p = 2/6

When the dice is rolled 12 times, the expected value is:

Expected = 2/6 * 12

Evaluate

Expected = 4

Hence, Brian is expected to roll a number greater than 4, 4 times

I think a fair argument for the green marbles is that it will be chosen 15/100 times, because if you add all marbles up you get 20 marbles in total, with 3 being green. If you multiply this by five you will get 15/100, therefore this is a reasonable prediction.

Answer: MN = 8.5

Step-by-step explanation:

Form it into a right triangle with MN being the hypotenuse (side opposite the right angle)

To make this a right triangle, plot a point at (8,-2) and connect the sides. The lengths of the legs that form the right angle are both 6 units. Use the Pythagorean theorem to solve for length of MN. a^2+b^2=c^2. (a and b are the legs that form the right angle and c is the hypotenuse)

6^2+6^2=c^2

36+36=c^2

72= c^2

8.48528137 = c.

Question says to round to nearest tenth of a unit

8.5 = c (line MN)

The regular price of a video game is $59.,95. This week it is on sale for 15% off. What does the game cost this week (before taxes)

Answers

Answer: $50.96

Step-by-step explanation:

The regular price of a video game is $59.95 and we are told that this week it is on sale for 15% off.

The game cost this week before taxes will be:

= 59.95 - (15% × 59.95)

= 59.95 - (0.15 × 59.95)

= 59.95 - 8.9925

= $50.9575

= $50.96

The amount this week is $50.96

Step-by-step explanation:

x² + y² -2x - 10y + 17 = 0

Find the center and radius of this circle

We have the equation

x² + y² -2x - 10y + 17 = 0

We collect like terms

x² - 2x + y² - 10y = -17

x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²

The center of the circle is point: C=(1,5).

The radius of the circle is r=3.

The average grade Jared received on 4 tests was 94. If he drops his lowest test grade of 85, what will his new average be?

A.72.75
B.76
C.89.5
D.97

Pls help TT

Answers

Answer:

total points on the 4 tests- 94x4= 376

376- 85= 291

291/3= D. 97

Answer:

D. 97

Step-by-step explanation:

x = sum of 4 test grades Jared received

[tex]\frac{x}{4} = 94[/tex]

x = 376

If he drops lowest test grade of 85, then subtract 85 from Jared's sum of all test grades:

x - 85 --> 376 - 85

= 291

Now that one of his test grades are not considered, this means there are only 3 test grades to consider.

291 must be divided by 3 to get the average:

[tex]\frac{291}{3}[/tex] = 97

The answer is D) 97

You Should get

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.  

8y^{2}+6y/2
