Answer:
-4/5
Step-by-step explanation:
2/5 ÷ -1/2
Copy dot flip
2/5 * -2/1
-4/5
The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps
Answer:
a
Step-by-step explanation:
a because the the sin is opposite divided by hypotenuse and the opposite of a is 12 and the hypotenuse is 13 so sin a would be 12/13
this is equals to the cosine of b because cos is adjacent/hypotenuse and the adjacent of b is 12 and the hypotenuse is 13 so cos b would be 12/13
hope this helps :)
Answer:
$480
Step-by-step explanation:
From the above question, we are told that:
A saleswoman earns 60% commission on all that she sells. Last month she sold $800 worth of merchandise.
The amount of commission (In dollars) she earned last month is calculated as:
60% of $800
= 60/100 × $800
= $480
Therefore, the amount of commission shoe earned last month in dollars = $480
The given triangle is a right angle .
In this triangle for angle A side AC is adjacent side ,BC is opposite side and AB is hypotenuse.
Sin of any angle is the ratio of opposite and hypotenuse .

Substituting the values of opposite and hypotenuse
SinA=
