1 answer:

7 0

The answer to the question above is option D: 18/ 9-a. If we try to analyze the word phrase above, this is the algebraic expression that matches it. When we say quotient, this is the number or the result of the division between two numbers. So the quotient of 18 and 9, this means that the answer of 18 divided by 9. And then, less than a. Less than a here means subtraction or minus. Therefore, this makes -a.

The time is 2:46 PM. What is the measure of the angle that the minute hand swept through since 2:00 PM?

Sonbull [250]

The minute hand has swept through 46 minutes on the clock. You have to set up a ratio to solve this:

$\frac{46\ minutes}{60\ minutes} = \frac{x\ degrees}{360\ degrees}$

You can compare the 60 minutes on a clock to 360 degrees because 60 minutes on a clock is one whole rotation. So then, you cross multiply and simplify:

$\frac{46\ minutes}{60\ minutes} = \frac{x\ degrees}{360\ degrees}\\\\46*360=x*60\\16560=60x\\276=x$

Therefore, the minute hand has swept through an angle with a measure of 276 degrees.

USPshnik [31]

Answer:

p=\frac{9}{7}

Step-by-step explanation:

$p - 12p + -2p - -19p + -13p = 9\\p(1-12+(-2)-(-19)+(-13)) = 9\\p(-11-2+19-13)=9\\p(7)=9\\p=\frac{9}{7}$
