What is 0.000012 pounds in word form

1 answer:

6 0

The answer is twelve millionth

In a scientific notation, you have to put a decimal right after the first number (unless it is a zero). How many times you move the decimal from its original spot determines the answer. (FYI: In a number like 196 the decimal point is 196.000<--here)
<span>
1.46000000 (moved the decimal point 8 times, so the answer is --->)
1.46×</span> $10^{8}$

Find the angles of the rhombus if the ratio of the angles formed by diagonals and the sides of the rhombus is 6:5.

Ainat [17]

Answer: Angles are $(\frac{1080}{11}) ^{\circ}$ and $(\frac{900}{11})^{\circ}$

Step-by-step explanation:

Here, the ratio of the angles formed by diagonals and the sides of the rhombus is 6:5.

Let the angles formed by diagonals and the sides of the rhombus are 6x and 5x.

Where x is any number.

Thus, By the property of rhombus,

Diagonals perpendicularly bisect each other.

Therefore, $6 x + 5 x + 90^{\circ} = 180^{\circ}$

⇒ $11 x + 90^{\circ} = 180^{\circ}$

⇒ $11 x = 90^{\circ}$

⇒ $x = \frac{90}{11}$

Therefore, the angles formed by diagonals and the sides of the rhombus are $(\frac{540}{11} )^{\circ}$ and $(\frac{450}{11})^{\circ}$

⇒ The angles of rhombus are $(\frac{1080}{11} )^{\circ}$ and $(\frac{900}{11})^{\circ}$

7 − 9x − (x + 12) less than or equal to 25?

Nonamiya [84]

Answer:

x ≥-3

Step-by-step explanation:

7 − 9x − (x + 12) less than or equal to 25

7 − 9x − (x + 12) ≤ 25

Distribute the minus sign

7 − 9x − x - 12 ≤ 25

Combine like terms

− 10x −5 ≤ 25

Add 5 to each side

− 10x −5+5 ≤ 25+5

− 10x ≤ 30

Divide by -10. Remember that this flips the inequality

− 10x/-10 ≥30/-10

x ≥-3

Grace has to remember a total of 108 measures of

Lemur [1.5K]

9514 1404 393

Answer:

52 measures

Step-by-step explanation:

Let s represent the length of the second song. Then the first song's length is 108 -s, and the difference in length is ...

(108 -s) -(s) = 4

108 -2s = 4 . . . .collect terms

54 -s = 2 . . . . divide by 2

52 = s . . . . . add s-2

Grace's second song is 52 measures long.

What are the zeros of f(x)= x^2+x-30

Westkost [7]

Answer:

Step-by-step explanation:

The zeros of the function is the roots and solutions. To find them, factor the equation into two binomials.

$x^2 + x -30\\(x+6)(x-5)$

To solve, set each binomial to 0 and solve for x.

x+6 = 0

x = -6

x-5=0

x=5

The data depicted in a histogram show approximately a normal distribution if the distribution

Slav-nsk [51]

Answer:

bunches up in the middle and tapers off symmetrically at either end

Step-by-step explanation:

By definition a normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Because the data towards the mean is more frequent in occurrence, the graph peaks at the center. The data occurs less frequently at the tail ends of the distribution, thus the shape of the distribution is a bell shape that peaks at the center and tapers off towards the tails. The key characteristic is that the distribution of data is perfectly symmetrical.

This is why the answer is:

The data depicted in a histogram show approximately a normal distribution if the distribution <u>bunches up in the middle and tapers off symmetrically at either end.</u>
