The first person who calculated pi was <span>Archimedes got really close however with the mathematics he had in his time he did not have decimal points nor could he use the number 0. So it has to latter once people recognize 0 as a number and the decimal point that we get what we have today. </span><span />
Answer:
3x +4x +5x +7x +2
19X+2
THE ANSWER IS 19x+2
Step-by-step explanation:
Answer:
152
Step-by-step explanation:
the second one, ((6 x 5) x 4) +((5 x 4) x 2) = 160
the third one, ((7 x 6) x 4) + (6 x 4) x 2) = 216
the fourth one, ((8 x 4) x 4) + ((4 x 3) x 2) = 152
Answer:
y = 3/2 x - 11
Step-by-step explanation:
y = -2/3 x + 5; slope = -2/3
Perpendicular line, slope is reciprocal and opposite so slope of the line that is perpendicular to the y = -2/3 x + 5 is 3/2
Passes through (8,1)
Equation
y -1 = 3/2 (x - 8)
y - 1 = 3/2 x - 12
y = 3/2 x - 11
Answer:
110
Step-by-step explanation:
To solve first find the measurement of the angles inside the triangle. The angle across from the 60-degree angle is also 60 degrees because the two angles are vertical.
Then you can find the missing angle in the triangle by subtracting 50 and 60 from 180 because all triangles equal 180 degrees. This means y=180-(50+60); therefore, y=70.
Finally, you can x because the 70-degree angle is complementary to x. This means when they are added they will equal 180. So to solve do x=180-70, which equals 110. Therefore, x=110.
