Even with the rounded pricing at the end, the total on the register is appropriate because it is only 23 cents off, which is a decent deal.
Answer:
10°
Step-by-step explanation:
In a right triangle, the ratio of the side opposite an acute angle to the hypotenuse is the sine of the angle. Here, that ratio is 80/445, so we have ...
sin(angle of elevation) = 80/445
Using the inverse sine function we can find the angle that has this sine value.
angle of elevation = arcsin(80/445) ≈ 10.36°
The angle of elevation is about 10°.
Answer:
The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. The second example is not a function, because it contains the ordered pairs (1,2) and (1,5).
Hope this helps you with your question.
The value of 300 is divided into 120 and 180 in the ratio of 2:3.
<u>Step-by-step explanation</u>:
- The total value is 300.
- This total of 300 should be divide in the ratio of 2:3.
Let us assume that the common factor be x in the ratio.
- The value of the part A is 2x.
- The value of the part B is 3x.
It is known that, 2x + 3x = 300
⇒ 5x = 300
⇒ x = 300/5
⇒ x =60.
<u>To find the values of A and B :</u>
A= 2x
⇒ 2(60)
⇒ 120
B= 3x
⇒ 3(60)
⇒ 180
The value of 300 is divided into 120 and 180 in the ratio of 2:3.
