To find the unit value, you divide the numerator and denominator of the given rate by the denominator of the given rate.
Answer:
x = 8 cm
Step-by-step explanation:
The first step in solving this problem is to determine which trig function applies. The diagram shows that this triangle is a right triangle, that side x is opposite the 25-degree angle, and that the hypotenuse has a length of 18 cm.
The sine function of an angle Ф is defined as the ratio of the opposite side to the hypotenuse. In this case, sin Ф (or sin 25 degrees) equals x/(18 cm).
We need to determine the value of x. Adapt the above equation to this particular situation: sin 25 degrees = x/(18 cm).
To solve for x, multiply both sides of the most recent equation, above, by (18 cm). The following results: (18 cm)(sin 25 degrees) = x.
Next, use a calculator to find the value of sin 25 degrees: It is 0.4226.
Then the desired value of x is (18 cm)(0.4226), or x = 7.61 cm. This should be rounded off to x = 8 cm to reflect the level of accuracy of the given 18 cm.
0.27 divided by 0.03 = 9
think of it this way it's like doing it 27 divided by 3 which is = 9
but then u see
9x3=27
9x0.3=2.7
so that must mean
9x0.03=0.27
u basically move the decimal point, in this problem its moved 2 or 3 times.
What i would do since $22.10 for 2.6 find out how much 1 pound of salmon is
so divide $22.10 by 2.6
which would equal $8.50
$8.50 per pound of salmon
hope this helped :>
