The fee for a balance transfer is 3% of the amount of the transfer. If b represents the amount of the balance transfer ana

DiKsa [7]

f=0.03b represents the relationship between fee charged and amount of transfer.

Step-by-step explanation:

Given,

Amount of balance transfer = b

Fee charged on balance transfer = f = 3%

Amount of fee charged on balance transfer = 3% of amount of balance transfer

Amount of fee charged = $\frac{3}{100}*b$

Amount of fee charged = 0.03b

Therefore,

f=0.03b

f=0.03b represents the relationship between fee charged and amount of transfer.

How to solve for x 15 + 8x = 45 + 6x

Reil [10]

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

15+8x=45+6x

Step 1: Simplify both sides of the equation.

8x+15=6x+45

Step 2: Subtract 6x from both sides.

8x+15−6x=6x+45−6x

2x+15=45

Step 3: Subtract 15 from both sides.

2x+15−15=45−15

2x=30

Step 4: Divide both sides by 2.

x=15

Answer:

x=15

Jerald jumped from a bungee tower. If the equation that models his height, in feet, is h = –16t2 + 729, where t is the time in s

Snezhnost [94]

Answer. First option: t > 6.25

Solution:

Height (in feet): h=-16t^2+729

For which interval of time is h less than 104 feet above the ground?

h < 104

Replacing h for -16t^2+729

-16t^2+729 < 104

Solving for h: Subtracting 729 both sides of the inequality:

-16t^2+729-729 < 104-729

-16t^2 < -625

Multiplying the inequality by -1:

(-1)(-16t^2 < -625)

16t^2 > 625

Dividing both sides of the inequality by 16:

16t^2/16 > 625/16

t^2 > 39.0625

Replacing t^2 by [ Absolute value (t) ]^2:

[ Absolute value (t) ]^2 > 39.0625

Square root both sides of the inequality:

sqrt { [ Absolute value (t) ]^2 } > sqrt (39.0625)

Absolute value (t) > 6.25

t < -6.25 or t > 6.25, but t can not be negative, then the solution is:

t > 6.25

Answer:

9x + 4y < 110

Step-by-step explanation:

This inequality works because its the cost of hammers ($9) multiplied by how many hammers are bought (x) plus the cost of wrenches ($4) multiplied by how many wrenches are bought (y). The total cost has to be less than 110.
