Answer:
For the first one
x= About 32.02
y= About 27.58
z= About 55.16
For the second one
x= 6
y= 12
z= about 16.97
Step-by-step explanation:
Their all really simple
These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.
Now for the first one ]
Lets find Z first
Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n
(I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for N
so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.
For the second one this is easier
We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N and we just plug in the n with 12 and solve it!
Answer:
10.2
Step-by-step explanation:
Length of arc=(2*pi*r)*(theta/360)
Length of arc=(2*pi*3)*(195/360)=10.2
Answer:
108
Step-by-step explanation:
<u>find the volume of the cooler</u>:
V=πr²h
π×6²×16= 1809.56
<u>find the volume of the cup</u>:
V=πr²(h/3)
π×2²×(4/3)= 16.76
<u>divide the volume:</u>
1809.56/16.76= 107.969
Assuming that the cooler is full to the max, and cups are filled almost to the top, the cooler contains 108 cups of water.
Answer:
Fourth and fifth ones are right
Step-by-step explanation:
Step-by-step explanation:
(8 x 3) + (8 x 2) = 8 x (3 + 2)
24 + 16 = 8 * 5
40 = 40
Hope it will help :)❤
