A candy store sells​ chocolate-covered almonds for ​\$7.50 per pound and​ chocolate-covered peanuts for ​\$5.00 per pound. The manager decides to make a bridge mix that combines the almonds with the peanuts. She wants the bridge mix to sell for ​\$7.00 per​ pound, and there should be no loss in revenue from selling the bridge mix rather than the almonds and peanuts alone. How many pounds of​ chocolate-covered almonds and how many pounds of​ chocolate-covered peanuts are required to create 65​ pounds of bridge​ mix?

32.5 lbs

Step-by-step explanation:

so divide 65 by 2 which will give you 32.5 it's eveny in half

Given f(x) = 9, find x if f(x) = -3x – 3.​

Rewrite the rational exponent as a radical by extending the properties of integer exponents. 2 to the 7 over 8 power, all over 2 to the 1 over 4 power

the eighth root of 2 to the fifth power

the fifth root of 2 to the eighth power

the square root of 2 to the 5 over 8 power

the fourth root of 2 to the sixth power

the eighth root of 2 to the fifth power .

Explanation:

What we have is:

Using the rules of exponents, we know that when we divide powers with the same base, we subtract the exponents. The base of each exponent is 2, so we subtract:

7/8 - 1/4

We find a common denominator. The smallest thing that both 8 and 2 will evenly divide into is 8:

7/8 - 2/8 = 5/8

This gives us:

When rewriting rational exponents as radicals, the denominator is the root and the numerator is the power. This means that 8 is the root and 5 is the power, which gives us:

,

or in words, the eighth root of 2 to the fifth power.

A.  2^(7/8) / 2^(1/4) = 2^(7/8) / 2^(2/8) = 2^(5/8)B.  ( 2^(1/8) ) 5 = 2^(5/8)C.  2^(8/5)D.  2^(5/8)E.  ( 2^(5/8) )^(1/2) = 2^(5/16)F.   ( 2^6 )^(1/4) = 2^(6/4) = 2^(1/3)

The area of a rectangular parking lot is 4982 m^2 if the width of the parking lot is 53m, what is it’s length of the parking lot?

92.3 m

Step-by-step explanation:

Area of rectangle = (length)(width)

4982 = (length)(53)

Length =

Length = 92.3 m (3 sf)

A large tank holds 400 gallons of salt water. A salt water solution with concentration 2 lb/gal is being pumped into the tank at a rate of 3 gal/min. The tank is simultaneously being emptied at a rate of 1 gal/min. If 100 pounds of salt was dissolved in the tank initially, how much salt is in the tank after 250 minutes?

So the tank contains 1866.67 lbs of salt after 250 minutes.

Step-by-step explanation:

The tank salt concentration at any moment is given as

Now the rate of change of concentration is given as

Here

SC_in is given as 2 lb/gal

FR_in is given as 3 gal/min

SC_tank is given in above equation

FR_out is given as 1 gal/min

Putting all in the equation gives

Multiplying by the integrating factor of on both sides

Integrating both sides with respect to t gives

For the initial condition Q(0)=100 lbs so the equation is given as

So the equation is

Solving for the t=250

Factor completely x2 + 8x - 20

For this it helps if you do a factoring table but since I will not for the sake of not having an image to show you, I will try and explain my answer.

The expression is:

x²+8x-20

In this case, since the x² doesn't have a number before it, we know that the beginning x's are solo, so we have...

(x+?)(x+?)

Now to solve the rest of the expression, we need to find two numbers that when multiplied equal -20 and when added equal 8.

a*b=-20
a+b=8

Lets look at the factor pairs of -20

(-1,20) or (1,-20) or (-2,10) or (2,-10) or (-4,5) or (4,-5)

Of all of these, only one pair have a sum of 8

So we can solve the expression

x²+8x-20=(x-2)(x+10)

X-2

The sum of two trinomials is 6x2 - 5x + 4. If one of the trinomials is 4x2 + 3x - 2, then what is the other trinomial?

Subtract the known trinomial from the total sum:

6x2 - 5x + 4 - 4x2 + 3x - 2 = 2X^2 -8x +6

The other trinomial is 2x²- 8x + 6.

Step-by-step explanation:

Consider the provided information.

The sum of two trinomials is 6x² - 5x + 4.

One trinomials is 4x² + 3x - 2,

To find the answer for this problem simply subtract them as shown:

6x² - 5x + 4 - (4x² + 3x - 2)

6x² - 5x + 4 - 4x² - 3x + 2)
