Describe two different ways that you could find the product 8 x 997 using mental math. Find the product and explain why your met

jolli1 [7]

One method is to round 997 up to 1000, multiply by 8, and then subtract 8 times 3. This would give you the solution of 7976.

Another method (Which I personally wouldn't use) is to recursively double 997. This is more difficult, although effective. After you double 997, double the resulting number, and then double the resulting number from that, you have the solution. This is because 2^3 is 8.

Using the digits 0 to 9 at most one time each. Fill in the boxes below to write three equations whose solution is 1/2

n200080 [17]

Step-by-step explanation:

There are many possible solutions. For example:

3x + 0 = 1x + 4

4x + 1 = 2x + 5

5x + 2 = 3x + 6

InWrite the equation of the line that passes through (7, - 4) and (- 1, 2) slope- intercept form.

blondinia [14]

Answer:

General Equation of a Line

$General Equation \\(y - y_{1} )= m (x-x_{1}) \\Slope=m= \frac{x_{2}-x_{1} }{y_{2}-y_{1} } \\\\Given:\\p_{1}=(7,-4)\\p_{2}=(-1,2)\\Solution:\\m=(\frac{-1-7}{2-(-4)}) =\frac{-8}{6}\\y-(-4) = (\frac{-8}{6} )(x-7)\\y+4=\frac{-8x}{6} + 56\\y=\frac{-8x}{6} + 52 \\\\The\\ equation \\ is \\ y=\frac{-8x}{6} + 52$

Step-by-step explanation:

Find the slope first and then place the values on the general formula. The final step is to solve for y

SI on rs 5000 at 10percent for a certain period is rs 500 less then the interest on rs 6000 at 10 percent p.A for the same perio

svet-max [94.6K]

Answer:

The time period was of 5 years.

Step-by-step explanation:

The formula to compute the simple interest is:

$SI=\frac{P\times r\times t}{100}$

The information provided is as follows:

$P_{1}=5000\\\\r_{1}=10\%\\\\P_{2}=6000\\\\r_{2}=10\%\\\\SI_{1}=S_{2}-500$

The time period is same for both the amounts.

Compute the time t as follows:

$SI_{1}=SI_{2}-500$

$SI_{2}-SI_{1}=500$

$\frac{P_{1}\times r_{1}\times t}{100}-\frac{P_{2}\times r_{2}\times t}{100}=500$

$\frac{6000\times 10\times t}{100}-\frac{5000\times 10\times t}{100}=500\\\\$

$600t-500t=500\\\\$

$100t=500\\$

$t=5\ \text{years}$

Thus, the time period was of 5 years.

If m ∠4 = m ∠5, then r||s. Summarize the postulate or theorem that makes this a true statement.

coldgirl [10]

The statement, m∠4 = m∠5, then then r||s is true based on the converse of corresponding angles theorem.

<h3>What is the Converse of Corresponding Angles Theorem?</h3>

Based on the converse of corresponding angles theorem, if two corresponding angles, angles 4 and 5 are congruent or equal to each other, then the lines on which they lie on, lines r and s are congruent.

Therefore, based on the converse of corresponding angles theorem, m∠4 = m∠5, then then r||s.
