PLS HELP What is the cos and sin for angle of rotation 30 degrees?

Answer:

the correct solution is B:3

Answer:

Our solution is option b, or in other words 3.

Step-by-step explanation:

This is more of a " guess and try " question. Say that 3 is the solution. If that is so, let us prove it, by arranging the values such that their addition is equivalent to 3 in each row.

Take - 3 as the first value in the first row. What other combinations can go with this, but still meet our requirement of a total of 3? The other two numbers must have a sum of 6, so let's list all possibilities -

{ 5 and 1 }

{ 4 and 2 }

Let us try 5 and 1. We should receive the following table so far -

| - 3 | 5 | 1 |

|   ?  | ? | ? |

|   ?  | ? | ? | ...... Now for this second row let - 2 be the starting value. The only possible values in the row should have a sum of 5 to have a total of 3 -

{ 3 and 2 }

This is the only possibility we have here. Plug it into our table,

| - 3 | 5 | 1 |

| - 2 | 3 | 2 |

|   ?  | ? | ? | .... Let's begin with the value - 1 for the third row. The only remaining values that could fill this row are 0 and 4. { - 1, 0, and 4 } add to 3, and hence the sum of the number in each row is a constant, 3. It has been proved.

| - 3 | 5 | 1 |

| - 2 | 3 | 2 | - This is our table.

| - 1  | 0 | 4 |

Answer: 16 more seniors than juniors stay at the after-school program

Step-by-step explanation:

50 * 60% = 50 * .6 = 30

30 * 80% = 30 * .8 = 24

50 - 30 = 20

20 juniors and 30 seniors in total

———————————————

20 * 40% = 20 * .4 = 8

24 - 8 = 16

16 more seniors stay after school or

Answer:

i dont know but ii wish i could help

Step-by-step explanation:

Answer:

1, 4 or 7

Step-by-step explanation:

The divisibility rule/shortcut for 3 is that the sum of its digits is divisible by 3. So, you currently have 29 (7+1+7+6+2+6+0), and you have to make that number divisible by 3.

adding 1 gets you 30, which we know is divisible by 3.

then, instead of trying every digit, we can note that

30 , 33 , 36 , 39 ....

are divisible by 3.

But the most we can add to the sum of 29 is 9 (because that is the highest digit possible)--so numbers above 38 are irrelevant

so, we want to find out if we can make 29 into 30, 33, or 36

adding 1 to 29 = 30

adding 4 to 29 = 33

adding 7 to 29 = 36

So, by making the first digit 1 , 4 , or 7, you make the number divisible by 3 (making the sentence true)

Answer:

35

Step-by-step explanation:

10 times 1/10 equals 1, so you don't need that since you are multiplying, but if you do, you end up with 35 x 1, which is still 35

35 is your answer

Hope this helps!

Answer:

see below

Step-by-step explanation:

y-intercept: (0,1)

rate of change: 2/3

Y-intercept: I found this because the y-intercept is when x=0, and where the line crosses through the y-axis.  So, we can see that the y-intercept is (0,1)

Rate of change: The rate of change is another word for slope, or rise/run, so we can see, from point (0,1), that the rise is 2 units up and 3 units to the right to another point where the line crosses a whole number point.

Hope this picture helps:

I like doing it first in mixed number.

50 goes into 200, 4 times.

1/5 of it is left so you add that to there =

Answer: 3 whole cupcakes

Step-by-step explanation:

3 halfs, 2 of those make 1, then you have 1 half left and 2 quarters, 2 quarters make one more half, then those two remaining halves make a whole which leaves you with 3

Answer:

\(2 \frac{1}{6} \)

Step-by-step explanation:

So we have

\(16 \frac{5}{6} \: and \: 18 \frac{2}{3} \)

If you have the same denominator for each fraction, you'd be able to subtract the numerators like regular subtraction

Seeing the 2/3, if we multiply each number by 2, you get

\(18 \frac{4}{6} \)

Now you have 5/6 and 4/6. Since they both have 6 at the bottom, you can subtract 5 and 4.

5-4=1

Now you have 1/6.

Then you can just subtract the 18 and 16 like normal giving you 2.

After we combine our numbers, we get 2 1/6. Hope this helps

5 is the answer.

What is a cuboid?

A cuboid is a rectangle, but in 3D form.

Do we calculate area or volume in a cuboid?

We calculate the volume for 3D shapes. For 2D shapes, area is used.

If/Then:

Now, if the volume of the cuboid is 24 units³ then:

x × x × y

Now, lets fit all our options to see which one is NOT the dimensions.

Option A:

x × x × 3 = 24 units³

x × x = 12 units³ ✔

This is possible.

Option B:

x × x × 4 = 24 units³

=> x × x = 6 units³ ✔

This is possible.

Option C:

x × x × 5 = 24 units³

=> x × x = 24/5 units³ ❌

This is not possible. This will be our answer.

Option D:

x × x × 6 = 24 units³

=> x × x = 4 units³✔

This is possible.

Conclusion:

So after working on our problem, we can conclude that C is our answer. Hoped this helped.
