Answer:
rhombus sides are equal.
7y=4y+21
7y-4y=21
3y=21
y=21/3
y=7
3x=45°(by alternate interior angle)
x=45/3
x=15
y
Answer:
The answer is in the explanation, parentheses are very important
Step-by-step explanation:
(-10)2 you use distribution so it will be -20
and the -102 would just be some number if with out the parentheses
Answer:
It would be a/c
Step-by-step explanation:
Since you're solving for angle F, you have to look at it from the angle F's perspective. Sin is opposite/hypotenuse. I recommended labeling the sides with H, O and A to make it less confusing. The letter opposite angle F is a, so you can label that "O". The side adjacent to angle F is b, so label that side "A" and the side c can be labeled as "H". Since sin is O/H, the correct answer would be a/c.
Cut it up
1 cylinder and a half sphere
V cylinder=hpir^2
Vsphere=(4/3)pir^3
find each
H=7
r=4
sub
Vcylinder=7pi4^2
V=7pi16
V=112pi
Vsphere (multiply by 1/2 later)
V=(4/3)pi4^3
V=(4/3)pi64
V=(256/3)pi
V=85.33333333333333pi
multply by 1/2 since 1/2 sphere
V=42.6666666666pi
add them
Vclliner+1/2sphere=112pi+42.66666666666pi=154.666666666666pi
pi=3.14 for problem
Vtotal=485.6533333333333333333
hundreth
V=485.65 in^3
