Let the ratio be termed as 4x and 2x.
Now,
4x + 2x= 90
or,6x=90
or,x=90/6
or,x=15
So the measure of angles are,4x= 4×15
= .........
and,2x=2×15 =.....

One shape is approaching a poor from the east traveling west at 15 mph and its presently 3 miles east east of the port I second
valentinak56 [21]

Answer:

DL/dt = 17 mph

Step-by-step explanation:

The ships and the port shape a right triangle

Ship  going west ( x-direction)   is traveling at 15 mph

Ship going north  (y-direction) is traveling at 10 mph

The distance L between ships is:

L²  = x² + y²

Tacking derivatives on both sides of the equation with respect to time

we get

2*L*DL/dt = 2*x*Dx/dt  + 2*y*Dy/dt    (1)

In that equation we know:

Dx/dt  = 15 mph

Dy/dt  = 10 mph

At the moment  ship traveling from the east is at 3 miles from the port

then x = 3 m  and the other ship is at 4 miles north

then by Pythagoras theorem

L = √ 3² + 4²    L = 5

By substitution in equation 1

2*5*DL/dt  = 2*3*15 + 2*4*10

10* DL/dt  =  90  +  80

DL/dt = 170 / 10

DL/dt = 17 mph

if you’re good with set theory and this sudoko puzzle in math 30 please help with question 33!! real answers only !!
Sidana [21]

Answer:  A) 2, 7, 9

<u>Step-by-step explanation:</u>

In a sudoku puzzle, there are three rules:

  1. Each vertical line must contain the numbers 1 - 9, with no duplicates
  2. Each horizontal line must contain the numbers 1 - 9, with no duplicates
  3. Each 3 x 3 box must contain the numbers 1 - 9, with no duplicates.

Using logic:

2 must go in the 1st box. It cannot go in the 2nd or 3rd shaded square because 2 is already in that 3 x 3 box.

That leaves the 2nd and 3rd shaded square.  

9 cannot go in the 2nd shaded square because 9 is already in that vertical line.

Therefore, 9 must go in the 3rd shaded square.

That leaves the 2nd shaded square.

7 must go in the 2nd shaded square because it is the only number remaining (2 and 9 have already been placed in the other squares).
