Value of x is 30°

Step-by-step explanation:

Step 1: Find value of x by using the trigonometric ratio cosine of x. Here, given that adjacent side is 16 and hypotenuse is 18

cos x° = adjacent side/hypotenuse = 16/18 = 8/9

x° = cos inverse(8/9) = 27.12° = 30° (Rounded off to nearest ten)

At a certain hospital 39080 patients had their falls reported in the winter of 2004, thisrose to 42045 patients in the winter of

Natali [406]

Answer:

Percentage rise in patients from 2004 to 2014 = 7.59%

Explanation:

The number of patients in 2004 = 39080

The number of patients in 2014 = 42045

Increase in the number of patients = (The number of patients in 2014) - (The number of patients in 2004)

Rise in the number of patients = 42045 - 39080

Rise in the number of patients = 2965

$\begin{gathered} \text{Percentage rise in patients = }\frac{\text{Rise in the number of patients}}{\text{Number of patients in 2004}}\times100 \\ Percentage\text{ rise in patients = }\frac{2965}{39080}\times100 \\ \text{Percentage rise in patients = }7.59\text{ \%} \end{gathered}$

Percentage rise in patients from 2004 to 2014 = 7.59%

a bakery has 4 trays with 16 muffins on each tray the bakery has 3 trays of cupcakes for 24 cupcakes on each tray if 15 cupcakes

stira [4]

64 muffins and 57 cupcakes. Since no muffins were sold, the amount of muffins wouldn't change. Since 15 cupcakes were sold, you just subtract 15 from the total amount of cupcakes (3 * 24 = 72; 72 - 15 = 57).
