Pierre ran 19 and 13/20 miles.
Given:
marathon length : 26 2/10 miles
pierre's length ran : 3/4 of the way.
Multiply the fractions.
Convert the marathon length from a mixed fraction into a fraction.
26 2/10 = ((26*10)+2)/10 = (260+2)/10 = 262/10
262/10 * 3/4 = (262*3) / (10*4) = 786/40 = 19 26/40
19 26/40 simplified to 19 13/20 miles
26 ÷ 2 = 13
40 ÷ 2 = 20
Answer:
No it can'tright angle triangle
Step-by-step explanation:
2, 2, √4 can't make a right triangle
By Pythagoras theorem the square of two sides equal to the third side of the triangle.
2^2+2^2=(√4)^2
4+4=4
8 is not equal to 4 so it not make right angle triangle.
Answer:
y=-3/2x+5
Step-by-step explanation:
3x+2y=10
2y=10-3x
2y=-3x+10
y=-3/2x+10/2
y=-3/2x+5
Solution
The diagram below will be of help
Note: Area of a Sector Formula
![Area=\frac{\theta}{360}\times\pi r^2](https://tex.z-dn.net/?f=Area%3D%5Cfrac%7B%5Ctheta%7D%7B360%7D%5Ctimes%5Cpi%20r%5E2)
Here
![\begin{gathered} r=15 \\ \theta=55^{\circ} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20r%3D15%20%5C%5C%20%5Ctheta%3D55%5E%7B%5Ccirc%7D%20%5Cend%7Bgathered%7D)
Substituting the parameters
![\begin{gathered} Area=\frac{\theta}{360}\pi r^{2} \\ Area=\frac{55}{360}\times\pi\times15^2 \\ Area=\frac{275}{8}\pi \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Area%3D%5Cfrac%7B%5Ctheta%7D%7B360%7D%5Cpi%20r%5E%7B2%7D%20%5C%5C%20Area%3D%5Cfrac%7B55%7D%7B360%7D%5Ctimes%5Cpi%5Ctimes15%5E2%20%5C%5C%20Area%3D%5Cfrac%7B275%7D%7B8%7D%5Cpi%20%5Cend%7Bgathered%7D)
There are two shaded portion (with the same Area)
Therefore, the area will be
![\begin{gathered} Area=2\times\frac{275}{8}\pi \\ Area=\frac{275}{4}\pi \\ Area=215.9844949 \\ Area=215.98\text{ square unit \lparen to the nearest hundredth\rparen} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Area%3D2%5Ctimes%5Cfrac%7B275%7D%7B8%7D%5Cpi%20%5C%5C%20Area%3D%5Cfrac%7B275%7D%7B4%7D%5Cpi%20%5C%5C%20Area%3D215.9844949%20%5C%5C%20Area%3D215.98%5Ctext%7B%20square%20unit%20%5Clparen%20to%20the%20nearest%20hundredth%5Crparen%7D%20%5Cend%7Bgathered%7D)
The answer is
Answer:
56 because a triangle is always 90 degrees so 90 minus 22 plus 12 equals 56
