Answer:
$76.80
Step-by-step explanation:
120/80 equals how many times the next route is larger than the first one. Which is 1.5 times larger.
Take the first earning of 51.20 and multiply by 1.5 to get 76.80
120/80=1.5
51.20*1.5=76.8
On the next route the truck driver earns $76.80.
Answer: 620≥ 427.57+ 11.38(4)+ (31.41) +57.75x
Step-by-step explanation:
So our limit is the 620$ that he has to spend. We know for a fact that the bike costs about 427.57 dollars. 4 $11.38 reflectors are purchased as well as gloves for 31.41. Now however many outfits he can purchase cannot exceed or go over his money limit of 620 so the variable (x) represents how many outfits he can buy without going over.

Answer:
Part 1) The shapes that make up the figure are two hemispheres and a cylinder
Part 2) see the explanation
Part 3) see the explanation
Part 4)
Step-by-step explanation:
Part 1) Define the shapes that make up the figure.
we know that
The shapes that make up the figure are two hemispheres and a horizontal cylinder
Part 2) Identify the volume formula(s) that will be be used for each shape in number 1.
we know that
The volume of a hemisphere is equal to
where
r is the radius of the hemisphere
The volume of a cylinder is equal to
where
r is the radius of the base of cylinder
h is the height or length of the cylinder
Part 3) Find the volume for each individual shape.
step 1
Find the volume of a hemisphere
we have
substitute
step 2
Find the volume of the horizontal cylinder
we have
substitute
Part 4) Find the composite volume of the original figure
The volume of the composite figure is equal to the volume of two hemisphere plus the volume of the cylinder
so
Convert to mixed number
