I really need help on these 2 questions. please help me if you can.

Answer: 167.55 units cubed

Step-by-step explanation:

To find this, you must know the formula for a cone. The area is A=πr(r+h2+r2). We can get that the A=π4(4+102+(4)2). We got this from plugging in the numbers. The radius is equal to half the diameter, so the radius is 4. The answer is 167.55 units cubed.

Answer:

a) 4x+6

b) 28

Step-by-step explanation:

The perimeter is equal to 1+x+1+x+1+1+1+x+1+x.

Simplifying we have 4x+6.

If we plug in 5.5 for x, we get 4*5.5+6=28

(c)

Step-by-step explanation:

we are given

length is x+1

width is x+3

height is x-3

(a)

we can use volume formula

now, we can plug it

now, we can simplify it

(b)

we are given volume =1001

so, we can set V=1001

and then we can solve for x

now, we can factor it

(b)

we are given volume

so, we can set

and then we can solve for x

now, we can factor it

Answer:

It's called a Diophantine Equation, and it's sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. One answer is x = 1, y = -1, and z = 2.

Step-by-step explanation:

Answer: A,B, D and E.

Step-by-step explanation:

When a cube with faces numbered 1 through 6 is rolled:

(A)The sample space is 1,2,3,4,5,6. Option A is correct

(B) P(rolling a 1) =1/6, Option B is correct

(C)P(rolling a 2)=1/6, therefore option C is incorrect.

(D)P(rolling a 6)=1/6, Option D is correct

(E)In an experimental trial, the outcome must be members of the sample space. Therefore, the outcomes in option (E), 2, 2, 2, 5, 3, 2, 6, 5, 6, 1 are valid.

Since all the sides are equal, the altitude is

10 sin60° = 5√3

To see this, draw the rhombus ABCD and drop an altitude from D to AB. Now you have a right triangle with hypotenuse=10 and base angle=60°

Answer:

C

Step-by-step explanation:

First, we have to find the equation that will give the rabbit population as a function of time and the initial population.

The equation we need turns out to be Population = a0 x 3y  where a0 is the initial population and y is the number of years,

To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.  

You can now find the difference in the number of rabbits at year 3 for the different starting populations.

Answer:

12

Step-by-step explanation:

Answer:

12 inches

There are 6 sunflowers that are 27 1/4 in, 3 27 1/2 tall and 4 27 3/4 tall. You add 6, 3 and 4 to get 13. The rest of the sunflowers add up to 7 (2+3+2), and 13-7= 6

Answer:

Answer is 71°

Step-by-step explanation:

Two angles are said to be

supplementary angles if their

sum is 180°.

******************************************

one angle ( x ) = 109°

Let the second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 109°

=> y = 71°

So,

Supplementary angle of 109° should be 71°

I hope this helps

Step-by-step explanation:

Answer:

Of the liquid surface fresh water, 87% is contained in lakes, 11% in swamps, and only 2% in rivers.

Step-by-step explanation:

The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.11

Rain and seasonal flooding cause water levels to fluctuate. In the wet soil, water-tolerant vegetation grows and helps maintain a moist, swampy condition. In many freshwater swamps in the southeastern United States, cypress and tupelo trees grow. ... Alligators, frogs, and many other animals live in these swamps.
