Answer:
17%
Step-by-step explanation:
If 30% of the school is girls and 10% wear glasses, that means that at least 3% of the school wears glasses. (10 percent of 30%) If 70% of the school is boys and 20% of boys wear glasses, at least 14% of the school wears glasses. (20% of 70%) If you add both of those numbers together it adds up to 17%.
Answer:y = (19 - 8x)/3
Step-by-step explanation:
add 8x to both sides ,
-3y = -19+8x
dividing both sides by -3
y = (19 - 8x)/3
6.040892193 E-4
which equals to
0.000604<span>0892193
move your decimal place 4 units to the left
because it's a negative (E-4), which makes your number smaller
OR
multiply that number by 10^-4</span>

Answer:
485.9 mm³
Step-by-step explanation:
The volume of a sphere is 4/3 π r³. So the volume of a hemisphere is half of that:
<h3>V = (2 / 3) π r³</h3>
V = 128π/3
The formula for the volume of a cylinder is V = Bh or V = πr²h .
The radius of the cylinder is 4mm and the height is 7mm
Substitute 4 for r and 7 for h in the formula V = πr²h .
<h3>V=π(4)²(7)</h3>
V = 112π
Since the figure is made up of a hemisphere and cylinder so volume will be sum of these two shapes
<h3>V = 128π/3 + 112π</h3>
= 485.9 mm³
