Answer:
20 days
Step-by-step explanation:
It takes 12 men 5 days to complete a job. Work out how many days it would take 3 men to complete the same job.
12 * 5 = 60
60/3 = 20
It will take 3 men 20 days to do the same job
The easiest variable you can solve for first is "z". Knowing that opposite angles of a quadrilateral inscribed in a circle are supplementary, subtract 93 from 180 to get z.
Z should equal 87.
The next variable we can solve for is "x". We know that inscribed angles are half the measure of their intercepting arc, so we know 93 is half of (112 + x). The equation would look like this:
93= (112 + x)/2
Multiply both sides by 2
186 = 112 + x
Subtract 112 from both sides
74 = x
Now we can apply the same method we used to find "x" to find y. Set up an equation like this:
80 = (y + x)/2
Substitute the value of x in
80 = (y + 74)/2
Multiply both sides by 2
160 = y + 74
Subtract 74 from both sides
86 = y
Hope this helps!
Answer:
180
Step-by-step explanation:
beacause if you did
45 x 4 = 180
180- 184 = 4
sorry it's 3 digit number
Answer:
48,970.7 in³
Step-by-step explanation:
If the diameter is 57.2 in, then the radius is half that, or 28.6 in.
The volume of a sphere is V = (4/3)πr³, and so the volume of this hemisphere is (2/3)πr³.
Substituting 28.6 in for r, we get the final answer:
(2/3)(3.14)(28.6)³ in³, or (to the nearest tenth of a cubic inch), 48,970.7 in³
