Which statement best describes the acceleration of the box?
A) The box accelerates at 1.0 m/s squared to the right because the net force is 17N to the right
B) The box accelerates at 1.9 m/s squared to the right because the greater force is to the right 9
The box accelerates at 3.0 m/s squared because the combined forces cause the box to accelerate
D) The box does not accelerate, because neither force is large enough to move the box

What is problem-solving?Problem-solving is the act of defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.
Problem-solving starts with identifying the issue. As an example, a trainer may need to parent out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

Fiona is x years old thomas is 3 years older than fiona cara is twice as old as fiona the sum of their ages is 51
The ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Fiona who is [x] years old. Thomas is 3 years older than Fiona. Cara is twice as old as Fiona the sum of their ages is 51.
We can write -
Age of Thomas = [y] = x + 3
Age of Cara = [z] = 2x
and
2x + x = 51
3x = 51
x = 17
Age of Thomas = [y] = x + 3 = 20
Age of Cara = [z] = 2x = 34
Therefore, the ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.

Answer:
To find percent change, we do: ( new-old / old ) * 100
So,
30 is old, 15 is new.
15 - 30 / 30
= -15 / 30 = -1/2 (100) = -50%
Answer:
15
Step-by-step explanation:
because 30 -15 = 15

Triangle IJK is similar to triangle LMN. Find the measure of side LM. Round your answer to the nearest tenth if necessary.
Answer:
It's either 39.2 or 39.3 (a more accurate answer) because it depends on what you round by. since it's Delta Math, you should get 2 attempts.
Step-by-step explanation:
Since they are similar, they are proportional.
54/11=4.90909091 or 4.9
Multiply 11 by 4.90909091 and you get 54
Multiply 8 by 4.90909091 and you get 39.3
if you multiply by 4.9 you get 39.2

Evaluate (6 +2i) / (3-i).
Answer:
2(4 + 3i) / 5
Step-by-step explanation:
(6 + 2i) (3 + i) / (3 - i) (3 + i)
=> 18 + 12i + 2i² / 9 - i²
=> 16 + 12i / 10
=> 8 + 6i / 5
=> 2(4 + 3i) / 5
Answer:
(6 +2i) / (3-i) = (6+2i)/(3-i) x (3+i)/(3+i) = (6+2i)(3+i) / (3-i)(3+i) = 6(3+i)+2i(3+i) / (3)^2-(i)^2 = 18+6i+6i+2i^2 / 9-i^2 = 18+12i+2i^2 / 9-i^2 = 6+12i+2i^2 / 3-i^2 = 2+12i+2i^2 / 1-i^2 = 2+12i+2 / 1 = 4+12ianswer.

Solve the system of equations by inspection. Explain your reasoning
-2x + 4y = 5
-2y + 4y = 6
PLEASE HELP ♡
Answer & step-by-step explanation:
Assuming the second equation is a typo and it's -2x+4y=6
No solutions. The quantity on the LHS is the same on both equation. You're basically required to find something that is at the same time equal to 5 and 6. Which is obviously impossible.

JKLM is a triangle. Find the measure of angle KL and JM
Answer:
x = 10
m∠K = 90°
y = 15
JM = 65
Step-by-step explanation:
KJ = LM
⇒ x + 31 = 5x - 9
⇒ 40 = 4x
⇒ x = 10
From inspection of the diagram, m∠K = 90° (right angle)
KL = JM
⇒ 4y + 5 = 2y + 35
⇒ 2y = 30
⇒ y = 15
JM = 2y + 35
⇒ JM = 2(15) + 35
⇒ JM = 30 + 35
⇒ JM = 65

Math of Finance: Chapter 2 Test
When we left James, he had decided to take a job at Jimmy John's as a sandwich artist with an expected salary of
$31,200 per year. James is really looking forward to the pay increase to help take care of his wife and two kids
After working four weeks, he gets his first check. It is much less than he expected. It turns out he will only get paid
for two weeks because Jimmy John's has a delayed paying process. Everyone gets paid two weeks after they work to
give Human Resources time to prepare the tax information. Since James gets paid every two weeks, a)what is his
gross income for his checks? His pay was much less. It tums out, other people get his money first. He had to pay
Federal Income Tax. b)Use the chart on the back of the test to determine his FIT. He also has to pay State
Income Tax. Oklahoma has a flat 5% tax. c)What is his SIT at 5% of his paycheck? Also, something called FICA
was on his paystub. His employer told him it was a required 6.2% tax for Social Security Retirement and a 1.45%
tax for Medicare when he gets older. d)Find James' Social Security Tax. e)Find his Medicare Tax. What is the
amount of FICA Tax listed as being withheld(add together)? Next came the big schock. Apparently, the
Republican Party still hasn't ended required healthcare. Because of this, James has to pay for group insurance with
Jimmy John's. It is $100 every paycheck, g)what percent of James' gross income is this each month? Finally,
James looks at the other category. It has two deductions listed. First, it has Sandwich Union Body Dues. Annual
dues are $130. h)How much was taken out for SUB dues just this paycheck? The second charged deduction for
other was IRA Retirement. He remembers signing up because Jimmy Johns' offers a matching 5%. If James' is
maximizing the match, i)how much is being taken out for retirement from his paycheck? After going over all the
numbers with his boss, it looks like James' check is correct. j)How much was his net income? If these numbers
remain consistent through the year, k)how much will James bring home for the year? DWhat percent of his
expected salary is this? James was really looking forward to his big paycheck. He thought he would have enough
money to get a loan on a new car. m)Do you think he should try to get the loan or not? n>Explain your opinion.
