84 words = 2 min
1 word = 2/84 = 1/42
420 words = 1/42 x 420 = 10 mins
Answer: 10 mins
Answer:
John has 2 dollars and 46 cents left after his purchases.
Step-by-step explanation:
50 - 17.50 = 32.50
32.50 - 24.99 = 7.51
7.51 - 6.99 = 0.52
0.52 + 5.00 = 5.52
5.52 - 3.06 = 2.46
i think itss this 45 45 90 triangle ratio
In a 45 45 90 triangle, the ratios are equal to: 1 : 1 : 2 for angles (45° : 45° : 90°) 1 : 1 : √2 for sides (a : a : a√2)Jun 26, 2020
Step-by-step explanation:
a) The circumference of a circle is 360 degrees. so:
7x+15+8x+6x+30=360
21x+45=315
21x=135
x=<u>15</u>
b) This means 7(15)+15=120, 8(15)=120, and 6(15)+30=120. Thus, by the inscribed angle theorem, all the angles measure 60 degrees, and the triangle is thus <u>equilateral</u> and <u>isosceles</u>.
