Answer:
c
Step-by-step explanation:
When we know two sides and the included angle, there is a formula we can use.
We know angle C = 35º, and sides a = 20cm and b = 19.5cm.
using the formula
Area =(½)ab sin C(angle)
Put in the values we know:
(20×19.5÷2)×sin(35)=
111.8474050885 cm^2
rounded = 111.85 cm^2
answer is c
An hourglass is turned over with the top part filled with
sand. after 3 minutes, there are 855 ml of sand in the top half. after 10
minutes, there are 750 ml of sand in the top half. This can be represents a two
points ( 3, 855) and (10, 750) . using this to solve the slope m =
(750-855)/(10-3) = -15. And using one point the equation is y = -15x + 900.
To solve this you can multiply the white
paint by
to find the amount of red paint to add which is 32/7 oz or roughly 4.5 oz
