Answer:

\frac{\pi }{2}

Step-by-step explanation:

One way to do this would be to find the circumference of the entire circle and divide it by 4, considering that the arc measure is 90 degrees

The radius is 1, and the circumference can be found by taking 2\pi r

So, the circumference of this circle is 2\pi

Now, all we have to do is divide that by four to get our answer

\frac{2\pi }{4} = \frac{\pi }{2}

Which number-line model represents the sum of 1.25+(-0.75)?
SIZIF [17.4K]

Solution:

<u>A few tips...</u>

  • Tip-1: If "+" and "-" are multiplied, it gives a result of "-".
  • Tip-2: If "-" and "-" are multiplied, it gives a result of "+".
  • Tip-3: If "+" and "+" are multiplied, it gives a result of "-".

<u>Changing the sign of the given equation.</u>

  • 1.25 + (-0.75)
  • => 1.25 - 0.75                                        [Sign changes according to tip-1.]

This could only mean that the arrow would go to <u>1.25 units forward.</u> Then a second arrow will be drawn to go <u>0.75 units back.</u>

The graph that matches with the above info is Option C.

PLZZZ HELP WILL MAKE BRAINLY
attashe74 [19]

Answer:

56

Step-by-step explanation:

To divide 364 into two parts in the ratio 15:11, add 15+11 to get 26. Now divide 364 by 26 to get 14. This counters 14 for each part, and we have 26 parts. If each part is x, and x=14, x times 15 will equal 15x=210, so the first number is 210. x times 11 will equal 11x=154, so the second number is 154. 210-154=56, so the first number is 56 bigger than the second.

And slope of the linear equation y+8=3(x−5)<br> ?
Triss [41]

Answer:

slope:  3; vertex:  (5, -8)

Step-by-step explanation:

Compare the given y+8=3(x−5) to the slope-vertex form y - k = m(x - h).  We see that the slope, m, must be 3 and the vertex must be (h, k):  (5, -8).
