<span>Each sphere of ice has a radius of 2cm
</span>one tray makes 6 spheres
<span>What is the total volume of ice the tray can make at one time?
Total volume of each sphere is </span><span>33.51 cm^3
The tray can hold 6 of these at a time
33.5 * 6
201 cm^3 total volume of ice that the tray can make at one time
Written in pi
64

cm^3
Hope this helps :)</span>
Answer:
X can be - 1/2 or 0.5
2x0.5=-1
Step-by-step explanation:
Answer:
w = 7 + x
Step-by-step explanation:
The formula for the area of a rectangle is
A = lw
56 + 8x = 8w
Divide both sides by 8
w = 7 + x
Answer:
A) ERROR
B) ∠C = 26°
Step-by-step explanation:
Houston, We have a problem!!! too much information
If we had a legit triangle, the law of sines would hold
19/sin138 = 8/sin20
28.395 = 23.390
as this is NOT an equality, the triangle does not exist as described.
IF it did, we'd get different results depending on which set we used
∠F = 180 - 138 - 20 = 22°
Law of sines
19/sin138 = DE/sin22 ⇒ DE = 19sin22/sin138 = <u>10.63697...</u>
or
8/sin20 = DE/sin22 ⇒ DE = 8sin22/sin20 = <u>8.762211...</u>
If we attempt to use Law of cosines
DE² = 19² + 8² - 2(19)(8)cos22 = <u>11.9639...</u>
so really none is correct because we attempt to use trig calculations to a non-triangle.
12) AC² = 15² + 19² - 2(15)(19)cos120
AC = 29.51270...
29.51270 / sin120 = 15/sinC
C = arcsin(15sin120/29.51270) = 26.1142... <u>26°</u>
