Answer:

1.Option: d.)3000m2

2. Option: b.)5000cm3

Step-by-step explanation:

Area And Volume Units Conversion

The area can be expressed in a variety of units like square meters, square inches, square kilometers, acres, hectare, etc. A similar situation happens with the volume, which can be expressed in units like cubic centimeters, cubic feet, cubic meters, liters, gallons, ounces, etc.  

1. The first part of the question gives nothing to do. The area is given in square meters and is requested in square meters, thus

3000\ m^2=3000\text{ square meters}

Option: d.)3000m2

2. One liter has 1000 cubic centimeters or 0.001 cubic meters, so

50\ lt= 50* 1000=50,000\ cm^3

Option: b.)5000cm3

A driveway is 81 ft. long, 6 ft. wide and 4 inches deep. How many cubic feet of concrete will be required for the driveway

Answers

The equation for volume is v = length x width x height.  We are given all of these, however one of the measurements is in different units than the others, so we need to convert the units before we do our multiplication...

4 inches x 1 ft / 12 in = 4/12 = 1/3 ft

Now we can multiply our equation...

v = length x width x height
v = 81 x 6 x 1/3
v = 486/3
v = 162 cubic feet
First the units must all be in feet.
4 inches has to be converted to feet 
4 inches x 1ft/12 inches = 4/12 ft = 1/3 ft

The driveway is a rectangular prism.
Area = length x width x height
Area = 81 ft x 6 ft x 1/3 ft = 162 cubic feet

Sandy has 16 roses,8 daisies,and 32 tulips.She wants to arrange all the flowers in bouguets.Each bouguet has the same number of flowers and the same type of flower.What is the greatest number of flowers that could be in a bouguet?

Answers

So,

We basically have to find the GCF, or Greatest Common Factor.

To find the GCF, factor all of the numbers and find the common numbers within them.

16 = 2 * 2 * 2 * 2
8 = 2 * 2 * 2
32 = 2 * 2 * 2 * 2 * 2

We can see that there are 3 2's in all of the numbers.  Therefore, the GCF must be the product of 3 2's, which is:
2 * 2 * 2 = 8

Therefore, the greatest number of flowers Sandy can have in each bouquet is 8.
If you want a total of eight bouquet then there can be seven flowers in each on. There can be four tulips, one daisy, and two roses. However if you're looking for a smaller amount of then you can go for four bouquets and have a total of 14 flowers in each one. You'd then have eight tulips, two daisies, and four roses!

12 - (x+3) = 10 need the answer fast but i need it right

Answers

12 - (x+3) = 10 \n \n12-x-3=10\n \n-x=10+3-12\n \n-x=1 \ \ /*(-1)\n \nx=-1
x= -1 
So first you have to find out which is which. 
So... lets look outside of the parenthesis, you have 12 and 10, and you know your taking something away from 12 which makes 10. 
So right away, i got -1 for x
so the equation would be,   12 - (-1 + 3 ) = 10
Now, Lets use, PEMDAS
p, stands for parenthesis, so, do we have parenthesis?? yes, so we do that first.
-1 + 3 = 2
now we have 12 - 2 = 10
E, stands for exponent, we don't have any exponents so we move on, M, multiply, we don't have anything to multiply, so we skip, D is divide, nothing to divide in this equestion so we skip this step also, A is addition, there are no addition signs, so we skip that step!! Now, We have S  which is Subtraction! we have a subtraction sign, so we have to see if 12-2 DOES equal ten, well my goodness! It does! So the answer is x = -1

Hope i helped. :D

Zoey made 5 and 1/2 cups of trail mix for a camping trip. She wants to divide the trial mix into 3/4 cup servings. Ten people are going on the camping trip. Can Zoey make enough 3/4 cup servings so each person on the trip has one serving?

Answers

No she can't.  We could divide 5 1/2 cups by 3/4 cups but there is an easier way.

Let's change 3/4 to .75 and multiply by 10 since we need 10 servings.

.75 x 10 = 7.5  so she would need 7.5 cups or 7 1/2 cups
Since she only has 5  1/2 cups,  she does not have enough.
