Answer:

The opposite of 45 is equal to the absolute value of -45.

Absolute value means switching to to a negative if it's a positive and if it's a negative to a positive. For 0, it remains 0 and doesn't switch to a -/+.

How do i use Scientific notation on these problems? Because I don't know...

saveliy_v [14]

Answer:

Simplify the problems first

Step-by-step explanation:

Before you can convert it to scientific notation, you should simplify it first.

#1 for example:

$(4 \times 10^5)^2\\$

Use PEMDAS to solve the equation:

$(4 \times 10^5)^2\\= 400000^2\\= 160000000000$

So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be $1.6 \times 10^{11}$ since there are 11 places after the decimal.

In which triangle is the measure of the unknown angle, x, equal to the value of sin–1(StartFraction 5 Over 8. 3 EndFraction)?.

almond37 [142]

The triangle is a right-angled triangle with a perpendicular side of 5 and a hypotenuse of 8.3.

<h2 /><h2>Given to us</h2>

$\theta = sin^{-1}\dfrac{5}{8.3}$

as we know that sine for any angle is the ratio of its perpendicular to the hypotenuse, and trigonometry is only applicable to a right-angled triangle.

therefore,

$\theta = sin^{-1}\dfrac{5}{8.3}\\\\sin \theta=\dfrac{5}{8.3}=\dfrac{Perpendicular}{Hypotenuse}\\$

Hence, the triangle is a right-angled triangle with a perpendicular side of 5 and a hypotenuse of 8.3.

Hailey rolls a twelve sided die, to choose a random number from one to twelve. What is the probability that the number hailey ro

Lemur [1.5K]

Answer:

7/12

Step-by-step explanation:

12 sided die has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 as the sides.

Two digits are 10, 11, and 12.

Even numbers are 2, 4, 6, 8, 10, and 12.

So two digits or even numbers are 2, 4, 6, 8, 10, 11, and 12. (7 total numbers)

P(Two digits or even) = 7/12
