With reference to the figure, sin x =
TEA [102]
Cos y = 16 / 17.89 = 0.8944
y = cos^-1 (0.8944) = 26.57°

tan 26.57 = BA / 17.89
BA = 17.89 tan 26.57 = 8.95

tan x = 17.89 / 8.95 = 1.999
x = arctan 1.999 = 63.43

sin x = sin 63.43 = 0.8944

lilavasa [31]

#Circle A

\\ \bull\tt\longmapsto 2πr=16

\\ \bull\tt\longmapsto 2(3.14)r=16

\\ \bull\tt\longmapsto 6.28r=16

\\ \bull\tt\longmapsto r=\dfrac{16}{6.28}

\\ \bull\tt\longmapsto r=2.6units

#Circle B

\\ \bull\tt\longmapsto πr^2=25

\\ \bull\tt\longmapsto r^2=\dfrac{25}{π}

\\ \bull\tt\longmapsto r=\sqrt{\dfrac{25}{π}}

\\ \bull\tt\longmapsto r=\dfrac{5}{\sqrt{π}}

\\ \bull\tt\longmapsto r=\dfrac{5}{\sqrt{3.14}}

\\ \bull\tt\longmapsto r=\dfrac{5}{1.74}

\\ \bull\tt\longmapsto r=2.94units

Circle B has bigger radius

Melinda says that 500 divided by 50 is 10. Use the drop-down menus to explain
IRISSAK [1]

Answer:

Melinda's statement is true.

Step-by-step explanation:

Division implies determination of the number of times that a given number would divide another given number. Example, dividing 100 by 20 means that how many 20s can we get from 100.

Melinda dividing 500 by 50 is trying to determine how many 50s can be found in 500. So that this gives 10.

i.e               \frac{500}{50}   =  10

Therefore, 50 would go in 500 in 10 times. Melinda's statement is true.
