Answer:
The cost for 5 songs is $5.35
Step-by-step explanation:
Find the unit rate for 1 song by dividing the total cost for 3 songs by 3
$3.21 ÷ 3 = $1.07
The unit rate is $1.07 per song, so multiply that by 5 to find the total cost for 5 songs
$1.07 * 5 = $5.35
Answer:
line
Step-by-step explanation:
you can obviously see lines in the shape
Volume of cone is 10
if the radius is r and height is h
while volume of cylinder is pi r 2nd power h,
volume of cone is 1/3 pi r 2nd power h.
hence with same r and h the volume of cone is one-third of that of cylinder and hence
volume of cone is 10.
Answer:
The height of tree house is 70.71 feet
Step-by-step explanation:
We are given that A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground
Refer the attached figure
Length of rope AC = Hypotenuse =100 feet
The top of a tree house to the ground forms a 45∘ angle of elevation from the ground =
We are supposed to find the height of tree house i.e.AB = Perpendicular
So, Using trigonometric ratio

Hence The height of tree house is 70.71 feet
The answer is "3600 ft²".
Left triangle area=(1/2) x (30 ft) x (72 ft) = 1080 ft²
Middle walkway area=(20 ft) x (72 ft) = 1440 ft²
Right triangle area
=same as left triangle area, 1080 ft²
Total area1080 ft²+1440 ft²+1080 ft² = 3600 ft²
Now you can also check that;
Parallelogram area = base x height = (50 ft) x (72 ft) = 3600 ft²
