Answer:

i think it's c

Step-by-step explanation:

ok so i think i get it, volume is width*length*depth so dividing the known volume by its width gives you the length*depth.

after that set up a porportion:

(L*W)of known/92 = x/46

solve for x gives you the length*depth of the unknown volume, times that but the 46 width.. i got 60

i think that's right but im not a teacher or anything

There are 10 coconuts at-the base of your tree. The coconuts are falling off the tree at a rate of 6 coconuts per week. Assume t

Sphinxa [80]

Answer: y = 6x +10.

After 7 weeks there will not be any coconut on the tree.

Step-by-step explanation: Given initial number of coconuts under the tree = 10 coconuts.

The rate of falling of coconuts each week = 6 coconuts per week.

Let us assume number of weeks be x and y be total number of coconuts after x weeks.

So, total number of coconuts after x weeks would be = Rate of falling of coconuts × number of weeks + Initial number of coconuts.

Therefore,

y = 6x +10.

a) y = 6x +10

Let us graph the linear equation with y-intercept 10 and slope rise/run = 6/1.

b) Total number of coconuts after x weeks = 52.

Plugging y=52 in above equation, we get

52 = 6x+10.

Subtracting 10 from both sides, we get

52-10 = 6x=10-10

42 = 6x.

Dividing both sides by 6, we get

42/6 = 6x/6

7 = x.

Therefore, after 7 weeks there will not be any coconut on the tree.

Find the perimeter and the area of each shape. Give your answer as a completely simplified exact value in terms of π (no approxi

nydimaria [60]

Answer:

Circumference: 12π + 8 cm,

Area: 48 ( cm )^2

Step-by-step explanation:

This figure is composed of circles, squares, and semicircles. As you can see, the squares indicate that each semicircle should have ( 1 ) the same area, and ( 2 ) the same length ( circumference ). It would be easier to take the circumference of the figure first, as it is composed of arcs part of semicircles the same length.

Circumference of 1 semicircle = $\frac{1}{2}$ ( πd ) = $\frac{1}{2}$ π( 4 ) = 2π ( cm )

Circumference of Figure (composed of 6 semicircles + 2 sides of a square),

We know that 6 semicircles should be 6 $*$ 2π, and as the sides of a square are equal - if one side is 4 cm, the other 3 are 4 cm as well. Therefore the " 2 sides of a square " should be 2

Circumference of Figure = 6 $*$ 2π + 2 = 12π + 8 ( cm )

_____________

The area of this figure is our next target. As you can see, it is composed of 3 semicircles, and the area of 3 semicircles subtracted from the area of 3 squares. Therefore, let us calculate the area of 1 semicircle, and the area of 1 square first.

Area of 1 semicircle = 1/2π $r^2$ = 1/2π $(2)^2$ = 2π ( cm ),
