Given
Ladder is 16 ft from bottom and 12 away from the base of the wall
In another case ladder is 18 ft above the ground and let say x ft away from the base of the wall
In both the cases the length of ladder remains the same
Using Pythagoras theorem, we can write
Answer:
3/52
Step-by-step explanation:
There are 13 types of cards (A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K), out of which 3 (J, Q, K) are face cards. This means that the probability for the first half is 3/13. There are 4 suites (Club, Spade, Hearts, and Diamonds). This means the probability of attaining a club is 1/4. 3/13 * 1/4 = 3/52
Eight cats for every three goats is a ratio between the cats and goat, so it would be 8:3
The best estimate to the nearest one percent of the fraction; 7/15 is; 47%.
<h3>What is the best estimate of the fraction to the nearest percent?</h3>
From the task content, it follows that the fraction given whose estimate is to be determined is; 7/15.
The fraction expressed as a percentage is;

Set up the equation by writing the number of students in the ratio as a fraction:
3/4= (245-x)/x Cross multiply:
3x= 4(245-x) Multiply on right:
3x= 980-4x Add 4x on both sides:
7x= 980 Divide both sides by 7:
x= 140 this is how many girls there are. And:
245-140= 105= boys
