Answer:

is the name of your account from little mermaid?  :DDD

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

now just refer to the above ( also copy and paste the above on your computer some where so you have it always)

sin( D )= 28 / 53

sin( E ) = 45 / 53

cos(D) = 45 / 53

cos(E) = 28 / 53

  1. 7:15 A.M.
  2. 1 hour and 45 min = 105 min
  3. 3 hour 45 min= 225 min
  4. 1 hour and 15 min = 105 min
  5. 105(2)+ 225= 435 min= 7 hours and 25 min.
  6. Add that to the original total you get 14:40 P.M

Juan scored 15 points more on this test than
maw [93]

Juan's least integer scores in both tests will be 85 and 100 respectively.

  • Test average of his two scores is atleast 92

Let :

  • Score on test 1 = b
  • Score on test 2 = b + 15

Average score can be related thus:

  • (Sum of score ÷ number of test) ≥ 92
  • (b + b + 15) ÷ 2 ≥ 92
  • (2b + 15) ÷ 2 = 92
  • 2b + 15 = 184
  • 2b = 184 - 15
  • 2b = 169
  • b = 169 ÷ 2
  • b = 84.5

Therefore, since both scores are integers, his least scores on both tests will be ::

  • 85 and (85 + 15) = 100

N is a positive intiger. Explain why 2n+1 must be an odd number.​
pogonyaev

Answer:

Because the number would be multiplied by an even number, which is 2. If the number (odd or even) is multiplied by two, then the result would be an <em>even number</em>.

Proof:

2(1) = 2

2(6) = 12

2(7) = 14

2(3) = 6

The number would then be added by an odd number, which is 1. If an even number is added with an odd number, then the result would be an odd number.

Proof:

2 + 1 = 3

12 + 1 = 13

14 + 1 = 15

6 + 1 = 7

What is the surface area of this rectangular pyramid?
Alexxx [7]

Answer:

304m^2

Step-by-step explanation:

First find the surface area of the base by multiplying the length by the width.

(12m) (8m)= 96m^2

Second, find the surface area of the front and back triangles using the formula <em>1/2 (base) (height)</em>. Use the length for the base.

1/2 (12m) (10m)= 60m^2

Next, find the surface area of the side triangles using the formula <em>1/2 (base) (height). </em>Use the width as the base.

1/2 (8m) (11m)= 44m^2

Last, add the surface area of each section. Make sure you add the area of each face.(we only solved for 1 of the front/ back triangles and 1 of the side triangles) To make it easier to understand I wrote out an equation to show how I added the surface areas.

base=a, front/ back triangles= b, side triangles=c

SA= a + 2b +2c  or SA= a +b +b +c +c

Using one of the equations above solve for the total surface area.

SA= (96m^2) + (60m^2) +(60m^2) +(44m^2) +(44m^2)

or

SA= (96m^2) + 2(60m^2) +2(44m^2)

SA=  (96m^2) +(120m^2) +(88m^2)

SA= 304m^2
