Answer:

  • B. sine

Step-by-step explanation:

In the given case you would use sine

  • sin  = opposite / hypotenuse
  • sin 47 = y/11
  • y = 11 sin 47
  • y = 8.0 (rounded)

Using cosine or tangent you wouldn't be able to find the value of y as the value of x is unknown

GIVEN:

p = y, b = x, h = 11, angle = 47°.

ANSWER:

We will use sin function to find the value of y,

so, sin47° = p/h

sin47° = y/11

y = sin47° × 11

y = 0.73135370 × 11

y = 8.03 or 8.0 rounded.

So, <u>Correct choice</u> - [B] Sine.

Write and solve a system of equations for this question please
andre [41]
Let b and s be the velocity of the boat and stream respectively....

3(b-s)=27

b-s=9

b=9+s  we will use this in the second equation....

2(b+s)=30

b+s=15, now use b found above in this to get:

9+s+s=15

2s+9=15

2s=6

s=3, and since from earlier b-s=9, b=9+s so

b=12

So the speed of the boat is 12mph and the stream is 3 mph

What is the slope of the line that crosses through points (0,0) and (1,2). How can Find the answer to the problem?
qwelly [4]

Answer:

The correct answer is m = 2/1 because they first point it reaches is (1,2) and so you insert those numbers (x,y) into the rise and run equation (y/x) and get the answer 2/1.

Hope this helps!

(Hint: M = Slope)

How many ways can three different numbers be selected from 10 numbers to open a keypad lock?
Paraphin [41]

There are 720 ways through which 3 numbers can be selected from 10 numbers to open a keypad lock.

Given that there are 10 numbers are 3 numbers are required to open a keypad lock.

Permutations are the number of ways in which objects can be selected without replacements to form subsets.

It is expressed as nP_{r}=n!/(n-r)!.

Factorial of a number is the product of consecutive numbers less than the number.

Total numbers available=10

Numbers to be selected=3

Number of ways can be found by using permutations.

Number of ways =10P_{3}

=10!/(10-3)!

=10!/7!

=10*9*8*7!/7!

=10*9*8

=720 ways.

Hence there are 720 ways through which 3 numbers can be selected from 10 numbers.
