Answer:

We are given that a store announced that their $500 appliances were on sale.

The price of the appliances after discount is $475.

We are required to find the percent discount on the appliances.

To find the percent discount, we have to use the below formula:

$\frac{(Actual-discounted)}{Actual} \times 100\%$

$\frac{500-475}{500}\times 100\%$

$\frac{25}{500} \times 100\%$

$0.05 \times 100\%$

$5\%$

Therefore, the percent discount on the appliances is 5%

10.) Part A: What is the area, in square feet, of the kitchen?

just olya [345]

The computation shows that the area of the kitchen that's in the home in square feet is 50ft².

<h3>How to calculate the area?</h3>

It should be noted that an area of a rectangular space is calculated by multiplying the length by the width.

In this case, the area of the kitchen will be:

= 5ft × 10ft

= 50ft²

Solve 4x - 3 = 18. Round to the nearest thousandth.

lorasvet [3.4K]

Answer:

$x=5.250$

Step-by-step explanation:

We have been given an equation $4x-3=18$ . We are asked to solve our given equation.

First of all, we will add 3 to both sides of our equation.

$4x-3+3=18+3$

$4x=21$

Now, we will divide both sides of our equation by 4.

$\frac{4x}{4}=\frac{21}{4}$

$x=5.25$

Upon rounding our answer to nearest thousandth (3 places after decimal) we will get,

$x=5.250$

Therefore, the solution for our given equation is $x=5.250$ .

(1 point) Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference betw

slavikrds [6]

Answer:

a. $\frac{dT}{dt}=k(T-Tm); T(0)=190$

b. $C_{0}=122$

c. $k=-0.00259$

d. $t=153.39838\\$ minutos

Step-by-step explanation:

a. Newton's law of cooling states that the speed with which a body is cooled is proportional to the difference between its temperature and that of the medium in which it is found. Then, the initial value problem is given by:

$Tm=68$

$\frac{dT}{dt}=k(T-Tm); T(0)=190$

b. The differential equation obtained is a differential equation of separable variables:

$\frac{dT}{T-Tm}=kdt\\\\\int {\frac{dT}{T-Tm}}=\int{kdt}\\\\Ln|T-Tm|=kt+C\\\\T(t)=C_{0}e^{kt}+Tm=C_{0}e^{kt}+68\\\\T(0)=C_{0}e^{k(0)}+68=190\\\\C_{0}=122$

c. After 33 minutes of serving the coffee has cooled to 180°:

$T(33)=122e^{33k}+68=180\\\\e^{33k}=\frac{112}{122}\\\\33k=Ln(\frac{112}{122})\\\\k=-0.00259$

$150=122e^{-0.00259t}+68\\\\Ln(\frac{150-68}{122})=-0.00259t\\\\t=153.39838\\\\$

The measurement of the complement of an angle exceeds the measure of the angle by 25%. Find the measurement of the angle and its

tester [92]

Let the angles be A and C

Complimentary angles, therefor 
A + C = 90 

The measurement of the complement of an angle exceeds the measure of the angle by 25% (you used a % sign so I'll use % instead of degrees) 
C = 1.25A 

Substitute 
A + 1.25A = 90 
2.25A = 90 
A = 40º <----- 
C = 50º <----- 
------------------------------ 

If you meant 25º 
A + (A + 25) = 90 
2A + 25 = 90 
2A = 65 
A = 32.5º 
C = 57.5º
