Answer:

The art is rectangular because (0.5)²+(1

2)²=(1.3)²

Step-by-step explanation:

This is testing your ability to recognize a rectangle is fundamentally composed of 2 right triangles, and asking you to apply the Pythagorean Theorem.

Therefore, we shall do just that:

{0.5}^{2}  +  {1.2}^{2}  =  {1.3}^{2}  \\ 0.25 + 1.44 = 1.69 \\ 1.69 = 1.69

So, the art is rectangular, and the answer is the first one.

Answer:

18) 4 * 10 ^ -10

19) t ^ 9

Step-by-step explanation:

18. When multiplying in scientific notation, just multiply the regular numbers together and add the exponents for the tens.

So it'll be 40 * 10^-11

However, the beginning number should have the decimal right after the 4, not any place after (for example, it's 3.056, not 30.56 or 3056.)

To fix this, move the decimal place forward one space from 40. to 4.0, and add 1 to the -11 power.

So the answer is now 4 * 10^-10

19. When dividing exponents, if the base number is the same, you can divide. (Basically, you can not divide x^2 and y^3 because x and y aren't the same)

Since in this case it's t, you can divide.

Dividing exponents is simple: just subtract them.

14 - 5 = 9

so the answer is t ^ 9

Use the Distance Formula to find the distance between each pair of points. (5,8) and (3,10)
andrew-mc [135]
The distance formula is shown here. If you plug your coordinates into the formula, you will get d=square root of (5-3)^2+(8-10)^2 which equals 2.828

Answer:

Option D

Step-by-step explanation:

From the spinner we see there are 5 colours in there.

These are;

Green, Yellow, Red, Purple, Blue.

This means that when it is spinned, there's possibility of getting only one colour per spin.

Since she tosses a coin as well for each spin, there's a possibility of getting either a tail or head per spin.

This means, all possible outcomes will be 5 × 2 = 10 outcomes.

With each colour possibly showing up with either tail or head.

Correct answer is Option D as it has 10 possible outcomes in the correct order.
