Answer:
Options (2), (3), (5) and (6)
Step-by-step explanation:
Let the number of bicycles = x
and the number of treadmills = y
Since, number of new bicycles must be more than 
times of new treadmills,
Inequality representing the statement will be,
x > y
Each bicycle costs $340 and each treadmill costs $670.He must spend less than $5650,
Inequality will be,
340x + 670y < 5650
And the number of bicycles and treadmills should be greater than 0.
x > 0
y > 0
Therefore, constraints for this situation are,
Option (2)
Option (3)
Option (5)
Option (6)
Answer:
22.5 grams of 10% cream is mixed with 37.5 grams of 2 % cream to prepare 60 grams of 5% cream.
Step-by-step explanation:
Let x grams of 10% cream is mixed with y grams of 2 % cream to prepare 60 grams of 5% cream.
So, x + y = 60 ............ (1) and
⇒ 10x + 2y = 300
⇒ 5x + y = 150 ............ (2)
Now, solving equations (1) and (2) we get,
4x = 150 - 60 = 90
⇒ x = 22.5 grams
So, y = 60 - x = 37.5 grams. (Answer)
Answer:
40
Step-by-step explanation:
s = 2;
h = 4
Surface area = 2s² + 4sh
= 2*2² + 4 * 2 * 4
= 2 *4 + 32
= 8 + 32
= 40 sq. units
