Can you help me I will mark you brainiest if you awnser all of them please put work into this

Answer:

Answer:

note:[tex]\theta =y[/tex]

Your answer is in the attachment.

we have

siny(cosy-siny)

taking - common from this

-siny(-cosy+siny)

-sin y(siny-cosy)

Answer:

divide by 4, 12, 21

Step-by-step explanation:

first, look at 20, and 5. How do you get there?

well, there are 2 possible ways.

20/4=5, or 20-15=5

we take it into the next pattern to get

44/4=11, and 44-15=29.

so now we know that the rule is to divide by 4

____________________________________________

36/4 = 12

84/4=21

Answer:

1. 36 / 4 = 9

2. 84 / 4 = 21

Rule: The input divided by 4. (I / 4 = O)

Step by Step explanation:

Look at the first input and output, what do you see? Well, 5 is a multiple of 20, but if 5 is the output, this means that instead of multiplication we're doing division. How many times does 5 go into 20? 4 times, so that's our rule, I / 4 = O. If we use this rule for the rest of the questions, you get the answer.

The surface area of the cone is 56.52 in².

An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.

As per the given diagram:

slant height of the cone (l) = 7 inch

radius of the cone (r) = 2 inch

For the surface area of the cone:

= πr(l+r)

= (22/7) × 2 × (7 + 2)

= (396/7)

= 56.52 in²

Hence, the surface area of the cone is 56.52 in²

Answer:

Number of shirts= 6

Step-by-step explanation:

Giving the following information:

The cost for several shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25.

First, we need to calculate the net total price paid  for the shirts:

Net total cost= 77.49 - 3.99= $73.5

Now, the number of shirts bought:

Number of shirts= 73.5 / 12.25

Number of shirts= 6

Answer:

the length of PQ is 8.9 m

Step-by-step explanation:

The computation of the length of PQ in meters is shown below:

Here we applied the Pythagoras theorem

c² = a² + b²  

 = 4² + 8²

 = 16 + 64

= 80

Now square root to the both sides

c = √80

=  8.94427191

= 8.9 m

Hence, the length of PQ is 8.9 m

Answer:

in big TRAINGLE

by using Pythagoras law

other side =√(6²+8²)=10yd

perimeter of composite figure =6+4+4+4+4+10=32yd

Answer:

(x-1)x4+1

each value is increasing by exactly 4 for each step shown, starting with 1.

so, 2 becomes

(2-1)= 1

1x4= 4

4+1=5

Answer:

ighhhhhhhhhhhh

Step-by-step explanation:

2 angles are complementary if the sum of their measures is 90°.

a) 90°-55°=35°

The complement is 35°

2 angles are supplementary if the sum of their measures is 180°.

b) 180°-53°=127°

The supplement is 127°

I found the question you were talking about here:-

Answer:

49 dollars

Step-by-step explanation:

10% of 50 is 5

50 - 5 = 45

8% of 50 is 4

45 + 4 = 49

Answer:

90

Step-by-step explanation:

88 plus 89 plus 90 is equal to 267

Answer:

a=8 b=6

Step-by-step explanation:

Using the Pythagorean theorem, a^2+b^2=c^2, and in this case, a^2+b^2=10^2 = 100

so a^2+b^2=100

8^2+6^2=100

64+36=100 ✔

and since A is longer than B, a=8, b=6

Answer: a= [tex]5\sqrt{3}[/tex] b= 5

Step-by-step explanation:

sin 60=a/10

[tex]\frac{\sqrt{3} }{2}[/tex]=a/10

[tex]10\frac{\sqrt{3} }{2} =a[/tex]

[tex]5\sqrt{3}=a[/tex]

cos 60=b/10

.5=b/10

5=b

every triangle adds up to 180 sort of, in this case, turn 4 into 40. 40+20=60 so add 80 to be 180!!!

Answer:

1,950 cubic units

Step-by-step explanation:

The computation of the volume of the prism is shown below:

Area of the rectangle = length × breadth

= 10 units × 13 units

=  130 units^2

Now the volume of the prism is

= Base × height

= 130 units × √(17^2 - 8^2)

= 130 units × 15 units

= 1,950 cubic units

Answer:

1,950 Cubic Units

Step-by-step explanation:

Because I said so.

Answer:

790 units^2

Step-by-step explanation:

Take the area of each side and add them all up. Remember each side is there twice.

Formula: SA = 2(15*5 + 15*16 + 5*16)

SA = 2(75 + 240 + 80)

SA = 2(395)

SA = 790
