Equation Answer is 1,000!

A good way to go about this is PEMDAS
P- parentheses
E - exponents
M - Multiplication
D- Divide
A - Addition
S - Subtract
since addition is before subtraction you would add 600+600= 1000 than you would subtract! 1000-200 = 800

Use the figure to the right to find the missing lengths of the triangle.
pychu [463]

To find AB(x) and BC(y), you can do(there are multiple ways you can do this):

tan A = \frac{y}{7}

tan 60° = \frac{y}{7} or (tan 60°) · 7 = y

tan 60° = \frac{\frac{\sqrt{3} }{2} }{ \frac{1}{2} } = \sqrt{3}

√3 · 7 = y

7√3 cm = y


sin B = \frac{7}{x}

sin 30° = \frac{7}{x} or x= \frac{7}{sin 30}

sin 30° = \frac{\frac{1}{2} }{1} = \frac{1}{2}

x = \frac{7}{\frac{1}{2} } = 14

x = 14 cm


AB = 14cm

BC = 7√3 cm

An analysis of the decay of 10 grams of an unstable element over time was completed and is displayed in the computer output.

The equation of the least-squared regression line is: In(Element) = 2.305 - 0.101(Time).

<h3>What is a regression line?</h3>

A regression line displays the connection between scattered data points in any set. It shows the relation between the dependent y variable and independent x variables when there is a linear pattern.

According to the given problem,

From the table we can see,

ln(Element) is the dependent variable and Time is the independent variable.

The constant = 2.305,

Time = -0.101

Hence, we can conclude, our least squared regression line will be

In (Element) = 2.305 - 0.101 (Time).

Write a summary about decimals that are equivalent to fractions with denominators of 10 or 100. EXTRA CREDIT
Flura [38]
Decimals that contain a zero in the tenth position can be thought of as a fraction over 100 as the tenth isn't occupied and the hundredth correlates to the 100 as a denominator. The same goes for a number with the tenth position occupied. These decimals would be put over 10 as they are occupying that position in the decimal.
