Answer:
First option: 6y^2sqrt(10) + 12sqrt(5y)
Step-by-step explanation:
3sqrt(10) * (2y^2 + 2sqrt(2y)
= 6y^2sqrt(10) + 6sqrt(20y)
= 6y^2sqrt(10) + 12sqrt(5y)
Answer:
74 and 27
Step-by-step explanation:
let x and y be the numbers
x + y =101........eqn 1
x - y = 47.......eqn 2
solve simultaneously
from equation 2, make x the subject
x= 47 + y........eqn 3
put eqn 3 into eqn 1
(47+y) + y = 101
47 + 2y = 101
2y= 101 - 47
2y=54
y= 54/2
y= 27
put y=27 into eqn 3
x = 47 + 27
x = 74
M < 2 = m < 6...corresponding angles
m < 5 = m < 8....vertical angles are congruent
Answer:
650/per hour
Step-by-step explanation:
I got this answer by dividing 1,625 by the amount of hours it took to fill that much water, 2.5 so basically i divided 1,625/2.5 to get my answer.
In similar triangles the ratio of the corresponding sides is equal.
Therefore in this case; the two triangles are similar;
hence;
5 in/ 15 in = 8 in / x
Where x is the unknown side
x= (8 × 15)/5
= 120/5
= 24 in
Therefore, the value of x is 24 inches
