Answer:
Given: Water in a reservoir dropped by 60%
Step-by-step explanation:
let the total water level of reservoir be 100.
then, in first year
the water reservoir dropped = 60% of 100
=
* 100
= 60
therefore, total water level needed to be restored till next year= 100
remaining water level to restore till next year= 100-60
=40
percentage= 
* 100
=40%
Answer:
7y^2 - y^2z - 10yz-5
C. 7 y squared minus y squared z minus 10 y z minus 5
Step-by-step explanation:
A. y squared minus y squared z minus 10 y z minus 5
B. y squared minus y squared z minus 5 y z minus 5
C. 7 y squared minus y squared z minus 10 y z minus 5
D. 7 y squared minus y squared z minus 2 y z minus 5
Given:
3y^2 - 6yz - 7 + 4y^2 - 4yz + 2 - y^2z
Collect like terms in the expression
3y^2 + 4y^2 - 6yz - 4yz - y^2z - 7 + 2
Simplify
7y^2 - 10yz - y^2z - 5
Rewritten as
7y^2 - y^2z - 10yz-5
Option C. 7 y squared minus y squared z minus 10 y z minus 5
Is the answer
Answer: 6cups of flour
Step-by-step explanation:
3cups of sugar to 2cups of flour
9cups of sugar to xcups of flour
Let sugar rep s
Flour rep f
So we have;
3s=2f
9s= xf
Cross multiply
3s×xf=2f×9s
Xf=2f×9s/3s
Xf=6f
Therefore, 9cups of sugar will be to 6cups of flour
X^2 - 10x + 15 = 0
x^2 - 10x = -15
x^2 - 10x + 25 = -15 + 25
(x - 5)^2 = 10 <====
x - 5 = (+-)sqrt 10
x = 5 (+-) sqrt 10
solutions are :
x = 5 + sqrt 10 and x = 5 - sqrt 10
