Answer:

x = 26.4      y= 17

Step-by-step explanation:

Set up proportions.


To find x:

Set 12 over x is equal to 10 over 22.


12 times 22 = 264

264 / 10  =x


x =  26.4


To find y:

Set y over 37.4 is equal to 10 over 22.


37.4 times 10 =  374


374 / 22


y = 17

Answer:

The answer to your questions are:

15.- 45 mg

16.- 25 kg

17.- 185 pounds

18.- 6 mg

Step-by-step explanation:

                                            D = (a M)  / (a + 12)

15.-

a = 4 years

M = 180

                                      D = (4 x 180) / (4 + 12)  = 720 / 16

                                      D = 45 mg

16.-                                1 pound --------------- 0.4535 kg

                                   55 pounds ------------  x

                                  x = 55 x 0.4535 / 1  

                                 x = 24.94 ≈25 kg

17.-                                1 pound --------------- 0.4535 kg

                                    x             ---------------   84.09 kg

                           x = 84.09x 1 /0.4535

                          x = 185.42 pounds  

18.-  M = 18 mg        what is 1/3 of the adult dose?

                          M = 18/3 = 6 mg

15. A cylindrical glass 10 cm tall and 8 cm in diameter is filled to 1 cm
ANTONII [103]

Answer:

No. The new height of the water is less than the height of the glass(6.33 cm<10 cm)

Step-by-step explanation:

-For the water in the glass to overflow, the volume of the inserted solid must be greater than the volume of the empty space or the ensuing height of  water >height of glass.

#Volume of the golf ball:

V=\frac{4}{3}\pi r^3\\\\=\frac{4}{3}\pi \times 4^3\\\\\approx 268.08\ cm^3

#The volume of the water in the glass:

V=\pi r^2 h\\\\=\pi \times 4^2\times 10\\\\\approx 50.27\ cm^2

We then equate the two volumes to the glass' volume to determine the new height of the water:

V=\pi r^2h\\\\(206.08+50.27)=\pi r^2 h\\\\h=318.35/(\pi \times 4^2)\\\\=6.33\ cm

Hence, the glass will not overflow since the new height of the water is less than the height of the glass(6.33 cm<10cm).
