Answer:

12 ft^2

Step-by-step explanation:

If you split up the 4 triangles you would have 8 right triangles

To solve for 1 right triangle you use the formula : 1/2 • l • h

1/2 • 1 • 2 = 1

Since there’s 8 right triangles you do:

8 • 1 = 8

Now the inner shape (a square):

2 • 2 = 4

Add up the areas:

8 + 4 = 12

May B. Luckie tosses a dart at the April calendar on the wall. What are the ODDS that the dart hits a date that is a prime numbe
meriva

Answer:

The ODDS that the dart hits a date that is a prime number are 1:1

Step-by-step explanation:

Odds:

An odd is writen as:

Number of desired outcomes: Number of undesired outcomes.

In this question:

April has 30 days, 15 of which are prime numbers and 15 of which are odd numbers.

So the odds are:

15:15

Simplifying by 15

1:1

The ODDS that the dart hits a date that is a prime number are 1:1

Five Questions FIFTY POINTS...look please don't just get this points I really need help in math rn. tysm for your help really ne
telo118 [61]

Answer:

1) 2 5/12

2) -3 1/30

3) 3/5

4) m = -28

5) b = -27

Step-by-step explanation:

1) You may be expected to solve this a different way, but how I prefer to solve these involves converting to "improper fractions", then making everything whole.

-11/3 = x - 5/4 (convert to improper fractions)

-44 = 12x - 15 (multiply everything by 12 to get whole numbers)

-29 = 12x (add 15 to both sides)

-29/12 = x (divide both sides by 12)

2 5/12 = x (convert to a mixed number, because that's what the question asks)

For clarity, that's two and five twelfths.

2) Same thing as above. I prefer improper fractions.

x + 17/6 = -1/5 (simplify and convert to improper fractions)

30x + 85 = -6 (multiply everything by 30 to get whole numbers)

30x = -91 (subtract 85 from both sides)

x = -91/30 (divide both sides by 30

x = -3 1/30 (convert to a mixed number, because that's what the question asks)

For clarity, thats minus/negative three and one thirtieth.

3) Same thing as above.

-(11/3)x = -11/5

-55x = -33

55x = 33

x = 33/55

x = 3/5

4) Same as above, but it's multiple choice! Yay!

-3m = 84

m = -28

5) You know the drill.

-b = 27

b = -27

I'd be happy to explain more if you need it at all. I'd recommend that next time this comes up, you post just one problem and see if you can understand the method so you can better learn how to do it on your own. Good luck (:

A. Name 3 different angles which could have a reference angle of 20 degrees. How did you arrive at this answer?.
IgorC [24]

<u>Answer:</u>

<u>Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .</u>

<u>Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .b. Reference Angle: the acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive.</u>

<u>Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .b. Reference Angle: the acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive.c. The rays corresponding to supplementary angles intersect the unit circles in points having the same y-coordinate, so the two angles have the same sine (and opposite cosines).</u>
