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.

In a group of dogs and their owners, there are exactly 20 heads and 64 legs. How many dogs are in the group
Juliette [100K]

Answer:

If we assume that everyone in the group is an owner, we would have

20*2=40 legs.

64-40=24 legs

Therefore, we need 24 more legs.

These 24 additional legs can be made from the difference of legs between the owners and dogs.

In this case, dogs have 4-2=2 more legs than an owner.

24 ÷ 2 = 12.

There are 12 dogs in the group.

Question 21
RUDIKE [14]

Answer:

y=-2x+1

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals of one another.  slope 1/2 perpendicular will be -2/1=-2

y-5=-2(x-(-2))

y-5=-2(x+2)

y-5=-2x-4

y=-2x-4+5

y=-2x+1

Answer:

D)

y > x + 4

y ≥ -3x - 2

Step-by-step explanation:

Blue line's boundary is above the line and dotted (>) so the equation: y > x + 4

Red line's boundary is above the line and solid (≥) so the equation: y ≥ -3x - 2

Answer

D)

y > x + 4

y ≥ -3x - 2
