ANSWER

The correct answer is A.

EXPLANATION

If you know the diagonals of a kite you can easily find the area.

The area of a kite is half the product of the diagonals.

From the graph, the from -5 to 4.

Using the number line approach. The longer diagonal is

|4 -  - 5|  =  |4 + 5|  =  |9|  = 9 \:  \: units

Similarly the shorter diagonal is from -4 to 4

|4 -  - 4|  =  |4 + 4|  =  |8|  = 8 \:  \: units

The area of the kite is:

Area= \frac{1}{2}  \times 8 \times 9

Area=4 \times 9

This implies that

Area=36 \: square \:  \: units

The first choice is correct.

Step-by-step answer:

Area of a kite is half of the product of the diagonals.

The length of diagonal in the x-direction is 4+5 = 9

The length of diagonal in the y-direction is 4+4 = 8

Therefore

Area of kite = 8*9/2 = 36 units.

Given:
Diameter = 8 cm
Height = 12 cm
Value of pi = 3

radius is 1/2 of the diameter. r = 8cm/2 = 4cm
Volume = π r² h
V = 3 * (4cm)² * 12 cm
V = 3 * 16cm² * 12 cm
V = 576cm³

Volume of the can is 576cm³. It is also the amount of milk inside the can.<span><span>COMMENTS </span> <span>REPORT</span></span>

Nicole has a job transporting soft drinks by truck. Her truck is filled with cans that weigh 14 ounces each and bottles that wei
Rufina [12.5K]

Answer:

W_{total} =  -56X + 68600

Step-by-step explanation:

We wil define:

1) "x" as number of cans inside the truck.

2) "y" as number of bottles inside the truck.

We now that the amount of both cans and bottles inside the truck is "980". This quantity is equal to the sum of cans and bottles, so now we can write:

X+Y=980

We will call this expression equation n° 1.

On the other hand, we know that the total weight is a sum of the weight of the cans and the weight of the bottles. The total weight of the cans, for example, is the result of  multiplying the numbers of cans in the truck with the weight of each can, like here: (W_{cans} = X * 14 oz

So now we can write:

W_{total} = (X*14oz) + (Y*70oz)

We well call this expression equation n° 2.

From equation n°1 we obtain "y", like this:

X + Y = 980\\Y = 980 - X

And we replace it in equation n°2:

W_{total} = (X*14) + (Y * 70)\\\\W_{total}  = 14X + 70Y\\W_{total}  = 14X + 70(980-X)\\W_{total}  =  14X + 68600 - 70X\\W_{total} =  -56X + 68600

Now we have the expression of the total weight considering the amount of cans in the truck.

*** IMPORTANT: there is a character similar to an "A" that i can't erase, maybe is a mistake from brainly. Do not consider it as part of the solution.
