Hey user!!!
given the radius of the cylindrical mold is 2 inches and height is 3 inches.
volume of the cylindrical mold = πr²h
= 3.14 × 2 × 2 × 3
= 37.68 in³
radius of the spherical mold is given = 2 inches
volume of the spherical mold = 4/3πr³
= 4/3 × 3.14 × 2 × 2 × 2
= 100.48/3 in³
difference between the amount of wax needed = 37.68/1 - 100.48/3
= ( 113.04 - 100.48 ) / 3
= 12.56/3
= 4.186...
so approximately 4.19 in³
hence, correct option is 4.19 in³
cheers!!!
Answer:
10+6+9+5= 40
So there are
are yellow cards 
are green cards 
are orange cards 
red cards
now we have to get the percentages
= 
= 
= 
= 
so the probability of getting...
<u>yellow is 25%</u>
<u>green is 15%</u>
<u>orange is 22.5%</u>
<u>red is 12.5%</u>

So first of all you can find x and y because all triangles have interior angles that add up to 180 degrees.
X= 10 degrees
Y= 60 degrees
Looking at the options, we see that the first statement is true. And if the angles are not equal, the triangles are not able to be similar.
Q1
Divide each distance by its time to find the speed for each driver.
T: 380 km / 4 hr = 95 km/h
M: 530 km / 5 hr = 106 km/h
Martine's average speed was greater.
Q2
Bronze to aluminum is 25:2
The alloy is bronze plus aluminum, so by adding 25 + 2 you get 27.
Bronze to total is 25:27
25 is 27 as x is to 55
25/27 = x/55
27x = 25 * 55
x = 50.926
Answer: 50.926 kg of bronze
Q3
Manipulative toys to art toys is 30:40
Total toys = 30 + 40 = 70
manipulative toys are 30 out of 70
30/70 * 100 = 42.9%
I believe it would be -16k^3 + 3v^4 - 9k^3 + 6v^4
