Answer:
(a) 120 square units (underestimate)
(b) 248 square units
Step-by-step explanation:
<u>(a) left sum</u>
See the attachment for a diagram of the areas being summed (in orange). This is the sum of the first 4 table values for f(x), each multiplied by 2 (the width of the rectangle). Quite clearly, the curve is above the rectangle for the entire interval, so the rectangle area underestimates the area under the curve.
left sum = 2(1 + 5 + 17 + 37) = 2(60) = 120 . . . . square units
<u>(b) right sum</u>
The right sum is the sum of the last 4 table values for f(x), each multiplied by 2 (the width of the rectangle). This sum is ...
right sum = 2(5 +17 + 37 +65) = 2(124) = 248 . . . . square units
Answer: 5 green buckets and 3 white buckets
Step-by-step explanation: each green bucket is 7 liters so if Austin buys 5 of them that'll equal 35 liters already. And each white bucket is 1 liter so if he buys 3 of those that'll get him to 38
First of 3/7 of a week is 3 days because there are 7 days in a week e out of seven so you get it?
1. The question is asking you how much barrels of raisins is used in three days but first you need to find out how much they use in 1 day (this is how I would do it) so turn all the fractions into a decimal
4/9 = 0.4444...
6/5= 1.20
3/7= 0.43
So now you got your decimals
2. Multiply 0.4444 by 1.20 now you got how much you get a day for cosmos bakery which is 0.53
3. Now go back to the 3/7 of a week which is 3 days and now you need to multiply 0.53 by 3 and you will get your answer
ANSWER!
1.59 a day for cosmos bakery
I HOPE THIS HELPED YOU TO SOLVE THIS PROBLEM AND SOME FUTURE ONES!
Answer: x ≥ 5
Step-by-step explanation:
7 is increased by the product of a number and 3: 7 + 3x
Is at least 22: ≥ 22
Your equation is: 7 + 3x ≥ 22
subtract 7 from both sides
3x ≥ 15
divide both sides by 3
x ≥ 5
