<span>The correct expression is
3a^2 + 4b^2
for a = 2 and b = 3
</span> 3*(2)^2 + 4*(3)^2=48
The answer in this case is 48
Answer:
D
Step-by-step explanation:
The mean or average is calculated by summing each element and then dividing by the number of elements.
We have: 35, 30, 45, 65, 44, and 21.
There are six elements in total.
We find the sum by adding. Hence:
We will now divide by 6, the number of elements:
Therefore, the mean runs scored by the batsman is 40.
Hence, our answer is D.
Too solve for expanded form, write each number with value separately.
600,000,000 + 40,000,000 + 400,000 + 9,000 + 200 + 10 is your answer
hope this helps
Answer:
1.65x + 2.25y ≤ 15
Step-by-step explanation:
Strawberries = $1.65 per pound Raspberries = $2.25 per pound
Amount with Christine = $15
Let
pounds of strawberries = x
pounds of raspberries = y
PxQx + PyQy ≤ 15
1.65x + 2.25y ≤ 15
The inequality which represent the situation where she buys x pounds of strawberries and y pounds of raspberries is 1.65x + 2.25y ≤ 15
1.65x + 2.25y less than or equal to 15
