To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Answer:
7 hours or 420 minutes.
Step-by-step explanation:
0.5 = 30 minutes
1.0 = 60 minutes
2.0 = 120 minutes
1.5 = 90 minutes
2.0 = 120 minutes
= 420 minutes
Every hour is 1.00 so 0.5 would be 30 minutes. I'll allow you to add up the time now.
Answer:
See below ~
Step-by-step explanation:
We need to represent the situations as inequalities.
===============================================================
<u>Students can work </u><u>no more than</u><u> 23 hours per week</u>
⇒ Let the hours per week be x
⇒ 'no more than' refers to less than or equal to (≤)
⇒ x ≤ 23
=============================================================
<u>Tutors are required to spend </u><u>at least</u><u> 2 hours per week</u>
⇒ At least refers to greater than or equal to (≥)
⇒ x ≥ 2
============================================================
<u>Tutors should spend </u><u>no more than</u><u> 7 hours per week</u>
⇒ As mentioned before, no more than refers to less than or equal to (≤)
⇒ x ≤ 7
Answer:
Step-by-step explanation:
length = 6 x 1/3 = 2 inches
width = 4 x 1/3 = 4/3 inches
height = 8 x 1/3 = 8/3 inches
volume = lwh = 2 x 4/3 x 8/3 = 64/9 cubic inches
Another approach is the following:
There are 6 x 4 x 8 = 192 cubes inside the prism,
Each cube has a volume of 1/27 cubic inches.
Therefore total volume = 192 x 1/27 = 192/27 = 9
