Answer:  the explanation is given below. The number is NOT an integer.

Step-by-step explanation:  We are given to check whether the number -0.5 is an integer or not.

We know that

an integer is a number where the digits after the decimal are zero, or the denominator of its fractional form is 1.

The given number is

n=-0.5.

Here, we can see that the digits after the decimal is 5, not zero. Also,  

this number can be represented as a negative fraction with denominator not equal to 1 is as follows :

n=-\dfrac{5}{10}=-\dfrac{1}{2}.

Therefore, this number is NOT an integer.

Yes, -0.5 is an integer because it is a negative number. Any number that is positive or negative is an integer.

Pyramid A is a square pyramid with a base side length of 18 inches and a height of 9 inches. Pyramid B has a volume of 3,136 cub
Basile [38]

The volume of pyramid B (3,136 in.³) is 323% bigger than the volume of pyramid B (972 in.³).

<h3>What is the Volume of a Square Pyramid?</h3>

Volume of square pyramid = 1/3(a²)h

Given the following:

  • Volume of pyramid B = 3,136 in.³
  • Base side length of pyramid A (a) = 18 in.
  • Height of pyramid A (h) = 9 in.

Volume of square pyramid A = 1/3(a²)h = 1/3(18²)9 = 972 in.³

3,136/972 × 100 = 323%

Pyramid B volume is 323% bigger than the volume of pyramid A.

A rectangular prism shaped fish tank is 14 in tall the perimeter of the base is 96 in the length of the base is 3 times the widt
Alla [95]

Using the given information find the length and width of the base:

Perimeter = 2L + 2W

L = 3W

Replace L in the first equation:

Perimeter = 2(3W) + 2w

96 = 2(3W) +2W

Simplify:

96 = 6W +2W

96 = 8w

Divide both sides by 8:

w = 96 / 8

w = 12

The width is 12 inches.

The length = 3 x 12 = 36 inches.

Volume = L x W X H

Volume = 36 x 12 x 14

Volume = 6,048 cubic inches.

Can someone help me with this task please? !!
viva [34]

Answer:

we need to get your brain thinking in this way. that you begin to understand how to do these things.

airways to say that your brain is not working that way, is not a valid excuse. we need to change that. your brain needs to get used to this way of thinking.

so, please, please, PLEASE go through the explanations below and tell me, where exactly in these explanations you stopped understanding what I was saying. so that I can better explain to you what is happening.

1. (0, -2)

2. 4

3. a geometric sequence. the common ratio is -2.0

4. the third option

5. the fourth option

Step-by-step explanation:

1. as x increases, y decreases. until, suddenly after x=0, this tendency reverses, and with increasing x also y increases. so, this is a turning point.

2. look at the line. it only starts with x>0 (it looks like x is around 1).

"input" is all the values of x the function has a defined result for (y = result values).

so, as there is no line for negative x, we can eliminate the first 2 answers.

x=0 is no valid answer either (as mentioned above, the line only starts well after x=0).

in the answer options the only x value having an y value above or below this x value is x=4.

3. look at the difference between 2 numbers next to each other in the sequence.

2.4 to -4.8

-4.8 to 9.6

and so on.

what do we need to do to get from the left to the right ?

we need to multiply by -2.

so, the relationship between "sequence item n" (an) to "sequence item n-1" (an-1) is a ratio, a multiplication factor :

an/an-1 = -2

4. it is completely simple. a function can be many things. on an x/y coordinate grid it can have gaps, it can have sharp direction changes,...

but there us one thing a function can never have : multiple different y values for one x value.

in the first graph x=2 has two different y values (-1 and -3). so, it is not clear what the result for x=2 would be. and that means, it is not a function.

in the second graph x=4 has two different y values.

in the third graph all is OK.

in the fourth graph x=-2 has two different y values.

so, only the third option is a function.

5. this function calculates the height of the thrown rock after t seconds of flight.

therefore, only the fourth answer makes sense.

A lion’s heart beats 12 times in 16 seconds.how many heartbeats will it have in 60 seconds?
Sergio [31]
Hey there!

Here is your answer:

<u><em>The proper answer to this question is "44 times".</em></u>

Reason:

You have to solve it this way:

<u><em>12 heartbeats=16 seconds</em></u>

<u><em>16+16=32</em></u>
<u><em>36+16=48</em></u>
<u><em>48+16=64</em></u>
<u><em>16-12=4</em></u>
<u><em>12+12=36+8=44</em></u>

<em>Therefore lions heart beats 44 times every 60 seconds.</em>

If you need anymore help feel free to ask me!

Hope this helps!
