Answer:
$0.20
Step-by-step explanation:
3.95/20 = 0.1975
0.1975 would round up to 0.20
Answer: 6 pounds of grapes
Step-by-step explanation:
There are 12 people that Joe is meant to buy for.
Each of them will receive 0.5 pounds of grapes.
All of them will therefore need:
= pounds of grapes per person * number of people
= 0.5 * 12
= 6 pounds of grapes
$27
2.65 x 2 (since he has to go both to and from work each day) = $5.30
Add the daily cost of the water bottle (1.45) to make his total cost for one day, which is 6.75
Multiply this number by 4 (because he goes 4 days a week) to get $27 for one week.
<u><em>Answer:</em></u>
K = -47.5
<u><em>Explanation:</em></u>
The zero of an equation is a number that when substituted in the equation gives the result zero
<u>We are given that:</u>
4 is a zero of f(x) = 3x³ + kx - 2
<u>This means that:</u>
When we substitute x = 4 in f(x) the result will be zero
<u>Therefore:</u>
3(4)³ + k(4) - 2 = 0
<u>Now, we simply solve for K as follows:</u>
3(4)³ + k(4) - 2 = 0
3(64) + 4k - 2 = 0
192 + 4k - 2 = 0
190 + 4k = 0
4k = -190
k = -47.5
Hope this helps :)
