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
Answer: y=-3x-4
Step-by-step explanation:
Since we know slope, we can plug it into slope-intercept form to find the y-intercept by using the given points,
y=-3x+b
8=-3(-4)+b
8=12+b
b=-4
Now that we know the y-intercept, we can complete the slope-intercept form.
y=-3x-4
Answer:
Step-by-step explanation:
Since both the triangles are similar, their sides will be in proportion. As one side is getting doubled, by SSS test of similarity, all the other sides will get doubled as well.
As the perimeter of a triangle is sum of its sides, the doubling of all sides will result in doubling of the perimeter.
Hence, perimeter of 2nd triangle = 14 cm.
Answer:
64 cm^2
Step-by-step explanation:
2*6 = 12/2 = 6
6 * 8 = 48
48+base= 48+16 aka. 4*4
64 cm squared
Answer:
10 feet.
Step-by-step explanation:
I am assuming this is a right triangle. We use Pythagoras theorem:
h^2 = 6^2 + 8^2
h^2 = 100
h = 10 feet.
