*. Your club is trying to raise money for a trip to Atlanta. They purchase boxes of candy to help fund the trip. Each box contains 60 candy bars. Each box costs $45. How much money does the club have to charge for each candy bar to make a profit of $39 per box? A. $2.60 per candy bar B. $1.25 per candy bar C. $1.40 per candy bar D. $2.69 per candy bar​

Answers

The school has to sell each box for $40 to make a profit of $10 per box because each box costs $30.
There are 50 candy bars per box.
$40/50=$0.80 per candy bar
It's costing the school $30/50=$0.60 per candy bar to buy.
The school sells each candy bar for $0.80, making a profit of $0.20 per candy bar.
50*$0.20=$10.00

Which equation can be used to solve for x in the parallelogram below?


A) 3x-12=6x+12

B) (7x-8)+(6x+12)=90

C) 3x-12=2x+8

D) (7x-8)+(6x+12)=180

Answers

Answer:

B. (3x - 12)° = (2x + 8)°

Step-by-step explanation:

This equation can be used to solve x.

3x - 12 = 2x + 8

3x - 2x = 12 + 8

x = 20°

-------------------------------------------------------------------

Verification:

3(20) - 12 = 2(20) + 8

60 - 12 = 40 + 8

48° = 48°

Determina el número de átomos que tiene una
muestra de 0.7 gramos de uranio puro si la
masa de un átomo de uranio es de 4 x 10^-25 kg​

Answers

Tomando el cociente entre la masa de la muestra y la masa de un átomo, veremos que hay 1.7*10^21 átomos de uranio en la muestra.

¿Como podemos determinar el número de átomos?

Para determinar el número de átomos en la muestra, simplemente debemos dividir la masa de la muestra (0.7 gramos) por la masa de un átomo de uranio (4*10^(-25) kg)

Donde la complicación viene por que tenemos distintas unidades.

Para resolver esto, podemos escribir la masa de la muestra en kilogramos.

Sabemos que: 1g = 1*10^-3 kg

Entonces podemos reescribir la masa de la muestra como:

0.7g = (0.7)*(10^-3 kg) = 7*10^-4 kg

Ahora si podemos tomar el cociente, el número de átomos esta dado por:

[tex]N = \frac{7*10^{-4}kg}{4*10^{-25}kg} = 1.7*10^{21}[/tex]

Así podemos concluir que hay 1.7*10^21 átomos de uranio en la muestra.

Autumn's family took a road trip to Mount Rushmore. Autumn fell asleep 39% of the way through the trip. If Autumn fell asleep after they had travelled 351 miles, what was the total length of the trip?

Answers

Answer:

900 miles long

Step-by-step explanation:

Given data

Le the total mile of the trip be x

Autumn fell asleep at 39% of the trip, which is equal to 351 miles

so

=39/100*x= 351

0.39x= 351

divide both sides by 0.39

x= 351/0.39

x= 900 miles

Hence the trip is 900 miles long

PROMT: Should the developed world care about and aid in the accessibility of education (science) and technology worldwide? My essay- Did you know that 32 million children in the Sub-Saharan area of Africa are uneducated. What should developed countries do to help this problem? I believe that to solve uneducation, developed countries should put forward more money and time into helping these countries with access to technology and education. One way that developed countries can aid developing countries is by giving access to technology. Access to technology will affect developed countries positively. One it will affect developing countries is that students will be able to access information better and have a higher chance of succeeding in school. Teachers in developing countries will also be affected because they can use it track the work of children better and will be to present information in an efficient manner. It can also affect the country by boosting is economy and help create new business. Even if technology can help developing countries, it won't be easy. First of all, most developing countries do not have power, and a lot of people don't bother going to school. These two things will make it harder because if there is no power how will the technology be used and if people don't really study then it won't aid that country at all. Despite the problems that technology will cause, there are solutions. The developed countries can give money towards constructing power lines in developing countries. Technology will encourage the people of developing countries to try to get and education, and this will cause more people to be educated. But even if that does happen, there will still be some problems in the way. In developing countries, some teachers don't know how to use technology in the correct way. Also some countries rarely have any schools, meaning that the developed countries will need to construct schools. Despite the amount of problems that will be caused due to developed countries aiding developing countries, it doesn't mean it's impossible. This will push Developing countries into trying to complete the goal of aiding developing countries in the aid of technology and education. pls look at the image and answer quickly!
