Answer:
=(m2p+−2r7)(m+−5p4r2)
=(m2p)(m)+(m2p)(−5p4r2)+(−2r7)(m)+(−2r7)(−5p4r2)
=m3p−5m2p5r2−2mr7+10p4r9
=10p4r9−5m2p5r2−2mr7+m3p

What is the area of the circle using π = 3.14?
113.04 in2
452.16 in2
1,017.36 in2
4,069.44 in2
Answer:
1017.36 in²
Step-by-step explanation:
Information we need to know:
Radius = diameter ÷ 2
Area of circle = πr²
1) Find the radius of the circle
We have to make sure the we are using the radius of the circle instead of the diameter as the formula using the value of r. If we were to use the diameter our answer would be wrong.
2) Find the area
To find area we can distribute the numbers given into the formula...
Hope this helps, have a lovely day! :)
Answer:A z-score is measured in units of the standard deviation. ... is two, the value 11 is three standard deviations above (or to the right of) the mean. ...

weeks she can make withdrawals from her account.
Answer:
400-40x x=6
Step-by-step explanation:
400 in total. minus 40 each week (x)
40 × 6= 240
400-240=160
Answer:
Step-by-step explanation:
608,000
you go to thousands look next number left and round up or down and the rest after the thousands becomes zeros
608,149 rounded to the nearest thousand is 608,000. The process involved looking at the digit in the hundreds place, determining it was less than 5, and therefore replacing it and all numbers to its right with zeroes.
To round 608,149 to the nearest thousand, you need to look at the digit in the hundreds place. This is the 1 in 608,149. Because 1 is less than 5, you leave the number in the thousands place (the 8 in 608,149) as it is, and change all the numbers to its right (149) in the original number to zeros. So 608,149 rounded to the nearest thousand is 608,000.

Weare given a regular figure, and asked for the measure of some indicated angles as shown below:
Notice that this is regolar figure (all sides of the same size) and also that is has 8 sides. Therefore, the central angle (360 degrees) must be divided by 8 to find the measure of angle <1:
angle <1 = 360 / 8 = 45 degrees.
Now, since the little triangles that the polygon is divided into, are all isosceles triangles (have the two sides connected to the center of the polygon, equal, then the other two angles inside each triangle must be equal (let's call them "x").
Now, for each little triangle we use the property that the addition of its internal angles must equal 180 degrees:
<1 + x + x = 180
45 + 2 x = 180
2 x = 180 - 45
2 x = 135
x = 67.5 degrees
Then <1 = 45 degrees , and <2 = 67.5 degrees.
