Answer: A compound inequality is an equation with two or more inequalities joined together with either "and" or "or". So, the answer would be the first one.

Explanation: When two inequalities are joined with and, they are often written simply as a double inequality.

Example: x ≥ -6 and x < 3 ; x < -12 or x ≥ 8

A ship is sailing on the sea. It travels 50 miles at 60° to the horizontal. Then the ship travels 90 miles at 30° to the horizon

pav-90 [236]

Answer:

$(25\sqrt{3}+45)\ miles$

Step-by-step explanation:

we know that

The total vertical distance (total miles North) traveled is equal to

$d=50sin(60^o)+90sin(30^o)$

Remember that

$sin(60^o)=\frac{\sqrt{3}}{2}$

$sin(30^o)=\frac{1}{2}$

substitute

$d=50(\frac{\sqrt{3}}{2})+90(\frac{1}{2})$

$d=(25\sqrt{3}+45)\ miles$

Can someone please answer. There is a picture. It is only one question. Thank you so much!

Charra [1.4K]

We can check each of these using the Pythagorean Theorem, $a^2 + b^2 = c^2$
Option A:
$.5^2 + 1.2^2 = 1.3^2

$
.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B
$1^2 + 2^2 = 3^2$
1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:
$6^2 + 8^2 = 10^2$
36 + 64 = 100
100 = 100
This option works
Option D:
$3^2 + 4^2 = 5^2$
9 + 16 = 25
25 = 25
This option works

So, after doing the calculations, we see that option B does not work
