Answer:
x = 5/4
y = 7/4
Step-by-step explanation:
The smaller triangle and the larger one are similar, so the sides are proportional.
(x+5)/5 = 10/8
x/5 + 1 = 1/4 + 1 . . . . . divide it out
x/5 = 1/4 . . . . . . . . . . .subtract 1
x = 5/4 . . . . . . . . . . . . multiply by 5
___
For y, you can do exactly the same computations, replacing every instance of 5 with a 7. Then you get ...
y = 7/4
Jake's guesses are illustrations of probabilities.
The probability that Jake's guesses are correct is 1/720
The sample size is:
--- 10 different numbers
The probability that Jake's guesses are correct is as follows:
- 1st guess = 1/10
- 2nd guess = 1/9
- 3rd guess = 1/8
So, the required probability is:
Hence, the probability that Jake's guesses are correct is 1/720

<h2>Given:-</h2>
<h3>perimeter of rectangle=26cm</h3>
<h3>Area of rectangle=>30cm²</h3>
<h3>{•°• perimeter of rectangle=2(l+b) }</h3>
<h3>{•°•. Area of rectangle=lxb}</h3>
<h3>So, 2(l+b)=26</h3><h3> =>(l+b)=26/2</h3><h3> =>l+b=13</h3><h3> =>l=(13-b) ----------(1)</h3>
<h3>Again,</h3>
<h3> =>lxb=30</h3><h3> =>(13-b)xb=30 {putting the value of l from equation 1}</h3><h3> </h3><h3> =>13b-b²=30</h3><h3> =>b²-13b+30=0</h3><h3> =>b²-10b-3b +30=0</h3><h3> =>b(b-10)-3(b-10)=0</h3><h3> =>(b-10)(b-3)=0</h3><h3> </h3><h3>or,</h3>
<h3> =>b=10 or b=3</h3>
<h3>putting the value of b in equation (1)</h3>
<h3> =>l=(13-b)</h3><h3> =>l=13-10=3 { taking b=10}</h3><h3> =>l=13-3=10 { taking b=3}</h3>
<h3>Hence, length=3 when breadth=10</h3><h3> length=10 when breadth=3</h3>
