olasank [31]

Answer:

To do this you must know the formula

absolute value of ( original-new)/original

In this problem the original is 2.4

2.4-3.00=-0.6, but take absolute value=0.6

0.6/2.4 = 0.25

0.25 as a percent is 25%

A Sixteen Foot ladder is leaning against a building. If the bottom of the ladder is sliding along the pavement directly away fro

Romashka [77]

Answer:

-0.69 feet per second

Step-by-step explanation:

We have dx/dt = 2 ft/sec, and we want to determine dy/dt.

x and y are related by the Pythagorean Theorem.

x²+y²=16²

Differentiate both sides of this equation with respect to t to get

$2x\frac{dx}{dt}+2y\frac{dy}{dt} =0$

$2y\frac{dy}{dt} =-2x\frac{dx}{dt}$

Divide both sides by 2y

$\frac{dy}{dt} =-\frac{x}{y}\frac{dx}{dt}$

When x = 5 ft, we have

x²+y²=16²

5²+y²=256

y²=256-25=231

therefore

y= $\sqrt{213}$

$\frac{dy}{dt} =-\frac{5}{\sqrt{213}}\frac{2 ft}{sec}$

=-0.69

The top of the ladder is sliding down (because of the negative sign in the result) at a rate of -0.69 feet per second.

The total price of a bag of peaches varies directly with the cost per pound. If 3 pounds of peaches cost $3.60, how much would 5

Levart [38]

<h3>Therefore the cost of 5.5 pound of peaches is $ 6.60.</h3>

Step-by-step explanation:

Given , the total price of a bag of peaches varies directly with the cost per pound. If 3 pound of peaches cost $3.60.

Therefore,

${\textrm{beg of peaches}}\propto{\textrm{cost}}$

$\Leftrightarrow {\textrm{beg of peaches}}= {\textrm{k cost}}$ .......(1) [ k is a constant]

cost = $3.60 when beg of peaches = 3 pounds

$3 = 3.60 k$

$\Leftrightarrow k = \frac{3}{3.60}$

$\Leftrightarrow k = \frac{1}{1.20}$

Therefore the equation (1) becomes

${\textrm{beg of peaches}}=\frac {cost}{1.20}$

$\Leftrightarrow {\textrm{beg of peaches}}\times 1.20={cost}$

When beg of peaches = 5.5 pound

$cost = 5.5 \times 1.20$

$\Leftrightarrow cost = 6.60$

Therefore the cost of 5.5 pound of peaches is $ 6.60.
