Answer:
45 miles per hour.
Step-by-step explanation:
you have to times 15 by 3 to get 45
and 20 times three is 60
I don’t know which one you need help with so I’ll answer #1. A triangle cannot have two right angles because the angles in a triangle have to add up to 180°. Since a right angle is 90°, two of those will make 180°. Since a triangle has three angles, that doesn’t leave anything for the third angle, and you can’t have a 0° angle. Also, you could have figured this out by trying to draw it, it’s impossible! This is because it would require a fourth line to complete the shape, which makes it a square!
Answer:
c. 3/8
Step-by-step explanation:
For each toss, there is a 50/50 probability that it lands on heads or tails. Let T be a tails and H be a heads, the sample space of this experiment is:
S={HHH, HHT ,HTT ,HTH, TTT, TTH, THH, THT}
The experiment has 8 possible outcomes. Only three of those outcomes have exaclty two heads (HHT, HTH, THH). Therefore, the probability of getting exactly two heads is 3/8.
Answer:
x=70
Step-by-step explanation:
sum is angles of a Pentagon=540°
x°+138°+2x°+80°+112°=540°
3x°+330°=540°
3x°=540°-330°
3x°=210°
3x°/3°=210°/3°
x=70

Alrighty
vsphere=(4/3)pir^3
vcylinder=hpir^2
vempty=vcylinder-2vsphere
first the cylinder volume
ok, the height=2 times the diameter=2 times 2 times radius=4 times 3.75=15 cm
the radius is 3.75
v=15pi3.75^2
v=15pi14.0625
v=210.9375pi
vsphere=(4/3)pir^2
vsphere=(4/3)pi3.75^2
vsphere=(4/3)pi14.0625
vsphere=(56.25/3)pi
vsphere=18.75pi
2vsphere=37.5pi cm^3
so vcylinder-2vsphere= 210.9375pi cm^3-37.5pi cm^3=173.4375pi cm^3
using pi=3.141592
vempty=544.8698625 cm^3
about 545 cm³
