Answer: 8.5 bushels weighs 238kg.
Explanation: 112/4 = 28
Each bushel weighs 28kg.
28 x 8.5 = 238kg.
Answer: B
. $23.42 is your answer
Hailey went to Frank’s Market and bought 1 3/4 pounds of coffee at $13 a pound and 8 1/2 pounds of rice at $0.45 per pound. If Hailey paid for her purchase with a $50 bill, how much change did she receive?
Answer:
$23.43
Step-by-step explanation:
First, you need to find the total amount she needs to pay for the items she purchased:
1 3/4=1.75
8 1/2=8.5
Total purchase=(1.75*$13)+(8.5*$0.45)
Total purchase=22.75+3.82
Total purchase=26.57
No, you need to subtract the total amount you have to pay for your purchase from $50:
$50-$26.57=$23.43
According to this, the answer is that she received $23.43 as change.
Answer: B. 17,621
Step-by-step explanation:
The growth rate is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 + r)^ t
Where
y represents the population after t years.
t represents the number of years.
b represents the initial population.
r represents rate of growth.
From the information given,
b = 16600
r = 1% = 1/100 = 0.01
t = 6 years
Therefore
y = 16600(1 + 0.01)^6
y = 16600(1.01)^6
y = 17621
Answer: This represents a function
Step-by-step explanation: In this problem, we are given a relation in the form of a mapping diagram and we are asked if it represents a function. The easiest way to do this problem is first translate the mapping diagram into a list of ordered pairs.
Notice that the 1 is connected with the 40, the 2 is connected with the 80, the 3 is connected with the 120, the 4 is connected with the 160, and the 5 is connected to the 200. We can also represent this as followed.
{(1,40), (2,80), (3,120), (4,160), (5,200)}
Now to determine if the relation is a function, we can simply look at the x-coordinates of each ordered pair. Notice that all the coordinates we have are different so this means that this relation must be a function.
Therefore, the relation shown here is a function.
