Answer:
P = 1.5x.
Step-by-step explanation:
Let the length of each side of the first triangle be x, then
Perimeter of this triangle
= 2x + 1.5x
= 3.5x.
So perimeter of smaller triangle is:
P = 1/2 * 3.5x
P = 1,.5x.
Her investment was $4500. To get this, you take 1890 and divide it by 7, giving you 270. This is 6% of 4500. To prove this, you would multiply 4500 by .06, giving the answer of 270, which can then be multiplied by 7 (years) to equal $1890.
2x+5x-4=31
7x-4=31
7x=35
X=5
ST=5x-4= 5.5-4=25-4=21
<h3>
Answer: 0.14</h3>
=======================================================
Explanation:
There are
- 5 students who got an A
- 35 students total
We divide these two values to get the probability we want
5/35 = 1/7 = 0.142857 which is approximate
This rounds to 0.14 when rounding to the nearest hundredth.
There's about a 14% chance of randomly selecting someone who got an A.
