Justin has a savings account.
• He started with $70 in his account.
• He deposits $15 into the account each week.
What is the total amount Justin will have in his account after 10 weeks?

Answers

Answer:

220

Step-by-step explanation:

Multiply 15 times 10 =150

150+70=220

Hope this helps :)

Answer:  220 dollars

==========================================================

Explanation:

After 10 weeks, he'll deposit a total of 15*10 = 150 dollars on top of the $70 already in the account. This means the grand total is 150+70 = 220 dollars

If you need to use algebra, then an algebraic expression you can use is 70+15x where x is the number of weeks. Replace x with 10 and you'll end up with 70+15*10 = 70+150 = 220. It's effectively the same idea and steps as the previous paragraph, but now we're involving a variable.

A company's flexible budget for 12,500 units of production showed sales, $50,000; variable costs, $20,000; and fixed costs, $15,000. The operating income expected if the company produces and sells 15,000 units is:

Answers

Answer: $21000

Step-by-step explanation:

First, we calculate the contribution margin which will be:

=Sales - Variable cost

= $50,000 - $20,000

= $30,000

Therefore, the contribution margin per unit will then be:

= $30,000 / 12500

= $2.4 per unit

The operating income will be the difference between the total contribution margin and the fixed cost. This will be:

The total Contribution margin will be:

= $2.4 × 15000

= $36000

Fixed costs = $15000

Operating income = $36000 - $15000

= $21,000

What is the probability of rolling a 20-sided number cube to a number that is prime or a multiple of 3?

Answers

Answer:

Probability of rolling a prime or multiple of 3 = 13/20

Probability of rolling a prime = 2/5

Probability of rolling a multiple of 3 = 3/10

Step-by-step explanation:

let's list primes and multiples of 3 from 1 to 20

Primes:

2 3 5 7 11 13 17 19

Multiples of 3:

3 6 9 12 15 18

Primes OR multiples of 3

2 3 5 6 7 9 11 12 13 15 17 18 19

There's 13 of them, so the probability of rolling a prime or multiple of 3 is 13/20

Probability of rolling a multiple of 3 is 6/20 = 3/10

Probability of rolling a prime is 8/20 = 2/5

Answer:

0.6 or [tex]\frac{12}{20}[/tex] or [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Here are the multiples of 3 (that are 20 or below) :

369121518

Here are the prime numbers (that are 20 or below):

235711131719

Some numbers are repeated in the two lists.

Here are all the numbers:

235679111213151819

12 numbers are prime or a multiple of 3.

As a fraction it will be [tex]\frac{12}{20}[/tex], or simplified to [tex]\frac{3}{5}[/tex]

As a decimal it will be 0.6

A package is shaped like a right rectangular prism. Use the dimensions shown to find the surface area of this package.

A)6 square feet
B)12 square feet
C)20 square feet
D)22 square feet

Answers

Answer:

The surface area is 22 square feet

Step-by-step explanation:

For a right rectangular prism, we have the formula for the area as;

A = 2(lb + lh + bh)

Accordingly, we have l as the length, b as the breadth and h as the height

Using the given dimensions, we have

A = 2(3(1) + 3(2) + 1(2))

A = 2(3 + 6 + 2)

A = 2(11) = 22 square feet

In fact, they prefer that she care for younger siblings instead of studying or completing a high school education. It is March. The student has told her parents that she has in-school suspension for the rest of the school year in order to have time to study, as she dreams of attending college one day.Directions: Read the scenario listed above. Complete all sections of the matrix provided below from the perspective of an individual in each of the six stages of Kohlbergs theory of moral development and the information from the provided scenario. Use complete sentences and include proper scholarly citations for any sources used.Level 1: Preconventional MoralityStageAdolescents PerspectiveRationale for your ResponsesStage 1: Obedience and Punishment OrientationThe adolescent should take care of her younger siblings because her parents want her to do so.A child assumes that those with authority hand down a set of rules which the child must obey unquestionably. In this case, the adolescent must unquestionably obey her parents desire for her to quit school to take care of her siblings (Gibbs, 2013).Stage 2: Instrumental Relativist Orientation/Exchange of FavorsThe child can go to the in-school suspension to improve her chances of going to college one day, or obey her parents and stay at home to take care of her siblings.The child recognizes that there is no single right view handled down by authorities and different individuals have different opinions. Everyone is free to pursue his/her own personal interests because everything is relative (Gibbs, 2013).Stage 3: Conventional Level/Good Boy or GirlThe adolescent should live up to her parents expectations of her taking care of her siblings. She should exhibit good intentions to her siblings by taking care of them.Goswami (2008) argues that children see morality as being more complex; people should conform to the expectations of their family and community and be good mannered. People should exhibit good behavior by having good feelings and motives such as empathy, love trust as well as concern for others.Stage 4: Maintaining the Social OrderShould go to the in-school program to enhance her knowledge.In this stage, the respondent is more concerned with the society in its entirety. They emphasize on respecting authority, obeying laws and performing ones duties to maintain the social order. One should not break the law whenever he/she feels they have a good reason (Gibbs, 2013).Stage 5: Social Contract and Individual RightsAdolescent should continue with her studies as it is her right to get basic educationRespondents believe that a good society is based on a social contract which they freely enter. They argue that basic rights should be protected (Goswami, 2008).Stage 6: Universal PrinciplesAdolescent should go to school as getting an education is a protected right.According to Gibbs (2013), Respondents in this stage almost consider the society as good. They believe people need to protect certain individual rights, and settle disputes democratically. Hoda is creating a report in Access using the Report Wizard.
