T = 44
j = 50
t - j = 6ft/sec
120ft ÷ 6ft/sec = 20s
(44 * 20) + 120 = 880 + 120 = 1,000 ...
50 * 20 = 1,000 ...
Ans = 20 secs...//
Answer:
i would go with the third option. III, II, I, IV
Step-by-step explanation:
Draw a line connecting the point to the center of the circle.
Construct the perpendicular bisector of that line.
Place the compass on the midpoint, adjust its length to reach the end point, and draw an arc across the circle.
Where the arc crosses the circle will be the tangent points.
Answer:
240
Step-by-step explanation:
Since David has 60 fewer storybooks than Huiling, take the total number of storybooks, which is 460 and minus it by 60.
460-60=400
Now, there are 5 units, 5units=400
1unit=80
Since Jenny has 3 times as many storybooks as David, Jenny has 3 units, 3unit=80x3=240
Tip: Draw a model to help you visualise the question better.
The answer when you simplify is 3e^2+6f-9
Basically what this is, is:
100% = 100/100
Basically, to get the fraction, you just set the denominator as 100 and move the percentage up. You can then multiply by as many powers of 10 as needed or simplify the fraction as many times as needed.
Ex:
78.7% = ?/100
Just put 78.7 into that question mark spot to get:
78.7/100 = 78.7%
Now, you multiply the whole thing by 10/10:
787/1000
So that's your fraction.
29% = ?/100
Then it would be,
29/100.
55.8%: 558/1000, you could simplify that by dividing both the numerator and denominator by 2, and you would get 279/500.
28.2%: 282/1000, simplify that: 141/500
82%: 82/100, 41/50
74%: 74/100, 37/50
91.8%: 918/1000, 459/500
72%: 72/100, 18/25
129%: 129/100
15.8%: 158/1000, 79/500
24.3%: 243/1000
93%: 93/100
