Answer 1

Answer:

8 crabs and 2 octopi

Step-by-step explanation:

Let c represent the amount of crabs and o represent the amount of octopi.

We can use this to set up a system of equations:

6c+8o=64

c=4o

We can solve this system using substitution. In this case, we can substitute 4o for c:

6(4o)+8o=64

24o+8o=64

Combine like terms

32o=64

Divide both sides by 32

o=2

Substitute 2 for o to solve for c:

c=4o=4(2)=8

There are 8 crabs and 2 octopi

This is the decision that provides a person with the maximum possible profits or advantages.

What is the Maximax decision in this case?

In this case, the maximax decision is a very large gasoline station because the possible profits add up to $325,000 ($25,000 + $300,000) and the possible losses are $100,000. This implies with this type of gasoline station Susan could maximize her profits even though there is a risk.

Marissa recently started working part time for a store that pays her $10. 80 per hour. She is expected to work a total of 19 hours per week. She will have the following deductions made from her gross pay for the week: Social Security (6. 2%) Medicare (1. 2%) State Income Tax (2. 5%) Federal Income Tax (12%) How much will her net paycheck be for the week?.

Answers

If Marissa get  $10. 80 per hour. and She work a total of 19 hours per week. and if She will have the following deductions made from her gross pay for the week: Social Security (6. 2%) Medicare (1. 2%) State Income Tax (2. 5%) Federal Income Tax (12%) then her net pay-check be for the week is $160.26

What is percentage ?

Percentage is a number or ratio expressed as a fraction of 100.

Given that per hour salary is $10.80

and she works 19 hours a week

so per week salary =[tex]19\times10.80=205.2\\[/tex]

Now she have following deduction

Social Security (6.2%)

Medicare (1. 2%)

State Income Tax (2. 5%)

Federal Income Tax (12%)

So total  deduction = 6.2+1.2+2.5+12=21.9%

Remaining after deduction =100-21.9=78.1%

So her net pay-check for the week can be calculated as

[tex]\frac{78.1}{100} \times205.2\\\\\\=160.26[/tex]

If Marissa get  $10. 80 per hour. and She work a total of 19 hours per week. and if She will have the following deductions made from her gross pay for the week: Social Security (6. 2%) Medicare (1. 2%) State Income Tax (2. 5%) Federal Income Tax (12%) then her net pay-check be for the week is $160.26

R is partly constant and partly varies with E, when R=530,E=1600 and when R=730,E=3600
Find the formular which connects R and E
Find R when E=1300

Answers

Hi there!

Please check the answer of the image attached for explanation.

Hope this helps....

The value of R at E = 1300 is 500 and the Equation that satisfies R and E is 10R = E + 3700.

What is a linear equation?

Because a straight line emerges when we attempt to display the graph of the provided linear function, a linear equation is known as linear.

Given, R is partly constant and partly varies with E, when R=530, E=1600, and when R=730, E=3600

Since R is partly constant and partly depends on E.

Let b Be the constant part of R and a be the part of R that varies with E

Thus,

R = a * E + b...(1)

Given at E is equal to 1600 R is 530 and at E is 3600 R is 730

Substituting these values in equation 1

530 = 1600a  + b......(2)

730 = 3600a + b........(3)

From comparing equation 2 and equation 3

2000a = 200

a = 1/10

from equation 2

b = 370

Thus, the equation in R and E:

R = 1/10 E + 370

=> 10R = E + 3700

Value of R at E = 1300

R = 130 + 370

r = 500

Therefore, the Equation that satisfies R and E is 10R = E + 3700.

Find an overestimate for 42 x 59 by adjusting each factor up to the next ten.

Answers

Answer:

Step-by-step explanation:

"To the next ten" means we will turn 42 into 50 and 59 into 60.

Since we are adding 8 to 42 and 1 to 60 this will not be exactly right, hence why it is an overestimate.

If, 5 * 6 = 30

Then, 50 * 60 = 3,000

the popularion of a city increases by 7% every year. if its population today is 300,000, what will its population be in 4 years. Write as an expression.

Answers

Answer:

Expression : 300,000 + 7x% = a

a = 384,000

Step-by-step explanation:

a = population in 4 years

x = every year increased

Expression: 300,000 + 7x% = a

300,000 + 7x% = a

replace x what will its population be in x years variable (this is 4)

300,000 + 7(4)% = a

multiply 7(4)

300,000 + 28% = a

Add 28% of 300,000 to 300,000

384,000 = a

The basketball reaches a maximum height of 86 feet after 1.5 seconds, so the vertex is (1.5, 86).f(x) = a(x − 1.5)² + 86We know the initial height is 50 feet, so plug in the point (0, 50) to find the value of a.50 = a(0 − 1.5)² + 86-36 = 2.25aa = -16f(x) = -16(x − 1.5)² + 86Simplify to get the standard form.f(x)
