m ≥ 15 graph the inequality

Answers

Since the sign is greater than or equal to, it’s a closed circle. I think that means it has a solution. Draw your number line than draw a circle on the 15th line. Make sure the circle is shaded in. Then draw a n arrow a cross the number line, pointing to the right because this equation is say the variable m is greater than or equal to 15

-4 (y - 2) = 12

what would “y” be?

Answers

Answer:

y = -1

Step-by-step explanation:

When solving this equation use the distributive property and get...

-4 (y - 2) = 12

-4y + 8 = 12

-4y = 12 - 8

-4y = 4

y = -1

Answer:

40⁰

Step-by-step explanation:

Main principles:

1.Alternate angles equal

2.Vertically opposite angles are equal

If angle 2 is 40⁰, then using the second principle,angle 3 is also 40⁰

Then, using the first principle,(alternate angles/angles that form any variation of "z"), angle 6 is also 40⁰.

There are other ways to do this like using co-interior angles, straight angles and other methods, these are the easiest to understand

It’s 40 degrees. Have a nice day!

PLEASE HELPPPP!!! Find the measure of angle A

Answers

Answer: 40

========================================================

Explanation:

The three angles of this triangle are

20x9026x-2

The square angle marker represents 90 degrees. It's also referred to as "a right angle".

As a rule, the three angles of any triangle always add to 180. Let's use this fact to solve for x

(angle1)+(angle2)+(angle3) = 180

(20x)+(90)+(26x-2) = 180

(20x+26x) + (90-2) = 180

46x+88 = 180

46x = 180 - 88 .... subtract 88 from both sides

46x = 92

x = 92/46 ........ divide both sides by 46

x = 2

Now that we know what x is, we can find angle A

angle A = 20x = 20*2 = 40 degrees

-------------

As extra info, we could also find the other angle with this x value

26x - 2 = 26*2 - 2 = 52 - 2 = 50 degrees

The three angles of the triangle are: 40, 50, 90 which add to 40+50+90 = 180. This helps confirm our answer.

Answers

Answer:

3.39 × [tex]10^{3}[/tex]

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. Since the decimal is going right, the exponent will be positive

What does a=? b=? Angle B=?

Answers

Answer:

If you were solving the right triangle, it would be:

m∠A = 46°

m∠B = 44°

m∠C = 90°

AB = 32

BC ≈ 23

AC ≈ 24

Step-by-step explanation:

To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:

m∠A = 46° (given)

m∠B = x

m∠C = 90° (given)

180 - (46 + 90) = x

180 - 136 = x

44 = x

m∠B = 44°

To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.

Recall that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

So:

sin46 = BC/32

BC = 32 (sin46)

BC ≈ 23

tan46 = BC/AC

AC = BC/tan46

AC = (23.01887361...) (tan46)

AC ≈ 24

One hundred forty-four of the 180 seventh-grade students attended the school dance last Saturday night. What percentage of seventh-grade students did NOT attend the dance?

Answers

Answer:

20%

Step-by-step explanation:

Because 144 OUT OF the 180 seventh grade students attended, this would represent 144/180.

But since we are trying to solve how many did NOT attend the dance, you must subtract 144 from 180 which equals 36. So 36/180 did not attend the dance.

But to make it a percentage, you divide 36/180. Fraction and percentage are like buddies! That's why it is very simple to make a fraction into a percentage.

36/180 can be simplified to 1/5, which as a decimal, is 0.20.

0.20 is same as 20%, so this should be the students that did not attend the dance.

I hope this helps. If this is wrong, I truly apologize...
