44% of a number x is 99
44%=0.44
0.44×99= 43.56
22% of a number y is 55
22%=0.22
0.22×55=12.1
the greater number is 44% of a number is 99 so the value is 43.56
Answer:
30 out of 50 times.
Step-by-step explanation:
1 attempt represents 3 out of 5 times.
10 attempts equals 1 attempt x 10.
Multiply numbers 3 and 5 by 10.
3 x 10 = 30
5 x 10 = 50.
Therefore, your solution is 30 / 50 times.
You found CD from the Pythagorean theorem to be ...
... CD = √(5² -2²) = √21
Since triangle ADC ~ triangle ACB, the ratios of corresponding sides are the same:
... AC/AD = AB/AC
... AB = AC²/AD
... AB = 5²/2 = 12.5 . . . . . . . the base of the overall triangle
_____
Then the area (A) is ...
... A = (1/2)bh
... A = (1/2)(12.5)(√21) ≈ 28.64 square units
_____
As you see here, the altitude of a right triangle divides it into three similar triangles. From smallest to largest, they are ...
... ADC ~ CDB ~ ACB
You can figure this using AAA similarity, since the smallest and largest triangles listed above share an acute angle vertex (∠A). That, together with the right angle, means all angles are congruent. After that, then you know ∠ACD ≅ ∠CBD, so you can show the middle sized triangle is similar to the other two.
Answer:
6.4

10% of the 50 were red.
10% * 50
(10/100) * 50
(1/10) * 50
= 5
5 were red.
