Answer:
is correct, he determines it correctly, he solved it correctly, 238.5
Step-by-step explanation:
Warning: This might be rough...
First draw it out. Label the angles at the corners of the triangle 60 (definition of equilateral triangles). Now draw a line from the center of the circle to the corner, splitting the corner in half. Label this line R and a corner as 30 degrees. No to find the height of this triangle, you do rsin(30). The base of this triangle is 2rcos(30). Now find the area of this mini triangle (rsin(30)*2rcos(30)/2=r/2*rsqrt(3)/2=r^2sqrt(3)/4). Now multiply this by 3 because you have 3 mini triangles... to get...

Answer: 19/50
Step-by-step explanation: To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100. In this case, 38% can be written as the ratio 38 to 100 or 38/100. Notice however that 38/100 is not in lowest terms so we need to divide the numerator and denominator by the greatest common factor of 38 and 100 which is 2.
38 ÷ 2 = 19
100 ÷ 2 = 50
<em>Therefore, 38% can be written as the fraction 19/50 which is in lowest terms.</em>
Answer:
18
Step-by-step explanation:
3*5=15
Therefore, every time she completed 3 pages that was a mark down.
3= 1/6 12=4/6
6=2/6 15=5/6
9=3/6 18=6/6 or 1 whole
The like terms are 23y & 2y and 7x & x because they have the same variables
