Answer:

The system of linear equations can be used to determine the number of pounds of each dried fruit in the mixture is:

p + c = 6....... Equation 1

4p + 5c = 4.40(6)....... Equation 2

Step-by-step explanation:

A health food store sells dried peaches (p) for $4 per pound and dried cherries (c) for $5 per pound. A six pound mixture of the two dried fruits cells for $4.40 per pound. Which system of linear equations can be used to determine the number of pounds of each dried fruit in the mixture?

Let the number of pounds of dried peaches = p

the number of pounds of dried cherries = c

We are told: health food store sells dried peaches (p) for $4 per pound and dried cherries (c) for $5 per pound. A six pound mixture of the two dried fruits cells for $4.40 per pound.

Hence: The system of equations is given as:

p + c = 6...... Equation 1

$4× p + $5 × c = $4.40(6)

4p + 5c = 26.4.......Equation 2

A person invests $1,150 in an account that earns 5% annual interest compounded continuously. Find when the value of the investme
AfilCa [17]

Answer:

11.1 years

Step-by-step explanation:

The formula for interest compounding continuously is:

A(t)=Pe^{rt}

Where A(t) is the amount after the compounding, P is the initial deposit, r is the interest rate in decimal form, and t is the time in years.  Filling in what we have looks like this:

2000=1150e^{{.05t}

We will simplify this first a bit by dividing 2000 by 1150 to get

1.739130435=e^{.05t}

To get that t out the exponential position it is currently in we have to take the natural log of both sides.  Since a natural log has a base of e, taking the natual log of e cancels both of them out.  They "undo" each other, for lack of a better way to explain it.  That leaves us with

ln(1.739130435)=.05t

Taking the natural log of that decimal on our calculator gives us

.5533852383=.05t

Now divide both sides by .05 to get t = 11.06770477 which rounds to 11.1 years.

13. What is the result of adding 5.4a + 7.1 and -1.28 - 6.3?
den301095 [7]

Answer:

C. 4.2a + 0.8

Step-by-step explanation:

Given:

The two binomials given for addition are:

5.4a+7.1 and -1.2a-6.3

Now, adding both the binomials, we get:

5.4a+7.1+(-1.2a-6.3)

Distributing the positive sign inside the second binomial, we get:

5.4a+7.1-1.2a-6.3

Now, combining like terms using the commutative property of addition, we get:

(5.4a-1.2a)+(7.1-6.3)

Simplifying the above expression, we get:

(5.4-1.2)a+0.8\\4.2a+0.8

Therefore, the resulting addition of the given binomials is 4.2a+0.8

Hence, option C is the correct answer.
