A nut mixture of peanuts and pecans at a small fair is $1.00 per pound of peanuts and $2.85 per pound of pecans. Over the entire

day, 97 pounds of the nut mixture were sold for $254.25. If p is the number peanuts and n is the number of pecans, then the system of equations that models this scenario is:
p+n=97
p+2.85n=254.25

Determine the correct description and amount of pounds for peanuts and pecans that were sold.

A.(75.0, 22.0) There were 75.0 pounds of peanuts and 22.0 pounds of pecans sold at the fair.
B.(12.0, 85.0) There were 12.0 pounds of peanuts and 85.0 pounds of pecans sold at the fair.
C.(22.0, 75.0) There were 22.0 pounds of peanuts and 75.0 pounds of pecans sold at the fair.
D.(85.0, 12.0) There were 85.0 pounds of peanuts and 12.0 pounds of pecans sold at the fair.

Answer:

  B.  (12.0, 85.0) There were 12.0 pounds of peanuts and 85.0 pounds of pecans sold at the fair

Step-by-step explanation:

Subtract the first equation from the second:

  1.85n = 157.25

  n = 157.25/1.85 = 85 . . . . . divide by the coefficient of n

Only one answer choice has 85 pounds of pecans—the one shown above.

Which of these statements best describes the relation shown in Item 1?
Oksi-84 [34.3K]

Answer:

The relation is 'a function that is one-to-many'.

Step-by-step explanation:

From the table, we can see that element 10 i.e. y=10 in the range, corresponds to two elements i.e. x=-5, and x=5 in the domain.

In other words, the given table represents the many-to-one function as an element of the range y = 10 corresponds to more than one element in the domain.

Therefore, the relation is 'a function that is one-to-many'.

Noah wants to put $1,000 in a savings account with a 1.5% annual interest rate. How much more money will he have after one year
11111nata11111 [884]
Assuming that the 1.5% annual interest is split into monthly basis with the same amount, then the monthly interest should be: 1.5%/12= 0.125%.
If you put $1000 for annual interest, the saving account would become: $1000*(100%+1.5%)= $1015

If you put $1000 for monthly interest, the saving account would become: ($1000*(100%+0.125%)= $1000*1.0151035559= $1015.10

Then, the money difference should be:  $1015.10-$1015= $0.10

Analyze the diagram to complete the statements. The m∠MXN is the m∠YZX. The m∠LZX is the m∠ZYX + m∠YXZ. The m∠MYL is 180° − m∠ZY
Xelga [282]

By using the picture that was provided below, you can see that

m<MXN is greater than m<YZX.  

Angles m<LZX is equal to m<ZYX + m<YZX and

m<MYL is equal to 180 degrees minus M<ZYX.


I hope this helps! Have a good day
