Answer:
Well first you would do (12.4-315) then you would -315 and you would get
Step-by-step explanation:
12.4-315=-302.6- -315
But the -315 becomes positive 315 because the minus and neg symbols rule each other out. So the next part would be -302.6-315= -617.6

If the side length of a square is 4 inches, its area is? And its perimeter is?
Answer:
The area would be 16, and the perimeter would be 16.
Step-by-step explanation:
Since it is a square we know that all the sides are the same length. The area formula is A = lw. You have to multiply 4 x 4 which is 16.
The perimeter formula is A = l(2) + w(2) 4 times 4 is 8. 8 plus 8 is 16. The perimeter is 16.
If this helped, I would appreciate it if you marked me brainliest. Have a nice day!
Answer:
wouldn't the perimeter be 20 cause its a square and a square has 4 equal sides so 4+4+4+4=20.

What is the solution to the system f(x) = 3x + 5 and g(x) = 3x + 12?
Answer:
The solution of the system of equation is x = 3.5
Step-by-step explanation:
The given system of equation is;
f(x) = 3·x + 5 and g(x) = x + 12
To find the common solution, we equate the values of both functions as follows;
3·x + 5 = x + 12
We collect like terms;
3·x - x = 12 - 5
2·x = 7
x = 7/2 = 3.5
x = 3.5
Therefore, the solution of the system of equation is x = 3.5
How many soap cakes can be placed in a box of size 56 cm x 0.4 m 0.26 m, if the size
of a soap cake is 7 cm x 5 cm x 2.5 cm?
Answer:
length of box = 56cm
breadth = 0.4m = 40cm
height = o.25m = 25cm
Volume of Box = Volume of soap × n
n = number of soaps.
LBH = lbh × n
56 × 40 × 25 = 7 × 5 × 2.5 × n
n = 56×40×25/35×2.5
n = 56000/87.5
n = 640
so, 640 soaps can be placed in the box.

Noah built a fenced dog run that is 8 yards long and 5 yards wide. He placed posts at every corner and every yard along the length and width of the run.
Answer:
The question is not complete, below is the completed question
Noah built a fenced dog run that is 8 yards long and 6 yards wide. He placed posts at every corner and every yard along the length and width of the run. How many posts did he use?
Answer
There are 28 posts in total
Step-by-step explanation:
Attached to this answer is a picture showing the fenced dog run and the position of the posts.
The number of posts is determined as follows:
Number of posts for the four corners = 4 posts
Number of posts for the 8-yard side = 7 posts
N:B There are 7 posts instead of 8 posts because one post has been counted as a corner post already, hence we will not count it twice.
∴ Total number of posts for both 8-yard sides = 7 × 2 = 14 posts
Number of posts for the 6-yard sides = 5 posts (same reason as above)
Ttal number of posts for both 6 yard sides = 5 × 2 = 10 posts.
Total number of posts = 4 + 14 + 10 = 28 posts
∴ There are 28 posts in total

-2x - 6y = -24
X-8y = -10
Answer:
x = -26 and y = -2
I hope this is the answer you are looking for
Step-by-step explanation:
x-8y = -10 => add 8y to both sides
+8y = +8y
x = -10+8y
-2(-10+8y) -6y = -24 => intersect what you got into the first equation
20-16y-6y = -24 => Distribute the -2
20-22y = -24 => subtract 20 in both sides
-20 = -20
-22y = -44 => divided by -22 in both sides
/-22 = /-22
y = -2
x-8(-2) =-10 => intersect the y into the other equation
x+16 = -10 => multiply -8*-2
-16 = -16
x = -26 => subtract 16 in both sides.

Simon bought a new laptop for $800 during the cyber monday sale. He paid $200 up front and will pay $60 a month until the balance is paid off. Fin the number of months ut will take simon to pay off his laptop?
Answer:
7 monthsStep-by-step explanation:
Step one:
given data
the cost of the laptop= $800
initial payment= $200
monthly payment = $60
let the number of months be x
the expression for the situation is the function for the equation of line
y=mx+c
Step two:
the expression for the situation is
800=200+60x
solve for x
800-200=60x
400=60x
divide both sides by 60
x=400/60
x=6.7

Which of the following is an arithmetic sequence?
O A. 0, 3, 8, 15, 24, 35, ...
O B. 9, 4, -1, -6, -11, -16, ...
O C. 1, 3, 6, 10, 15, 21, ...
O D. -1,0,1,0,3, 0, -..
Answer:
B. 9, 4, -1, -6, -11, -16, ...
Step-by-step explanation:
An arithmetic sequence is when there is a constant difference between terms. And in this case if you count the spaces in between each number, you get that each one is less than the last by 5. Whereas the other ones change constantly.
The sequence 9, 4, -1, -6, -11, -16, ... has same common difference. Therefore, option B is the correct answer.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.
A) 0, 3, 8, 15, 24, 35, ...
Here, common difference is 3-0=3, 8-3=5, 15-8=7.....
Common difference is not same, so the set of numbers are not in arithmetic sequence.
B) 9, 4, -1, -6, -11, -16, ...
Common difference is 4-9=-5, -1-4=-5, -6-(-1)=-5
Common difference is same, so the set of numbers are in arithmetic sequence.
C) 1, 3, 6, 10, 15, 21, ...
Common difference is 3-1=2, 6-3=3, 10-6=4
Common difference is not same, so the set of numbers are not in arithmetic sequence.
D) -1,0,1,0,3, 0, ...
Common difference is 0-(-1)=1, 1-0=1, 0-1=-1
Common difference is not same, so the set of numbers are not in arithmetic sequence.
Therefore, option B is the correct answer.

If you want to be a millionaire by age 70, and you start saving $50 a month at age 18 (with no previous savings), what expected rate of return do you need to reach your goal? A. Between 8% and 8.9% B. Between 9% and 9.9% C. Between 10% and 10.9% D. 11% or more
9514 1404 393
Answer:
B. Between 9% and 9.9%
Step-by-step explanation:
The equation for the sum of a series of monthly payments P earning interest rate r compounded monthly for t years is given by ...
A = P((1 +r/12)^(12t) -1)/(r/12)
The number of years in this case is ...
70 -18 = 52
We want to find r such that ...
1,000,000 = 50·12((1 +r/12)^(12·52) -1)/r
10,000/6 = ((1 +r/12)^624 -1)/r
We can try some values for r to see what may work.
r = 9%
((1 +.09/12)^624 -1)/.09 = 1165.60 . . . not quite enough
r = 10%
((1 +0.10/12)^624 -1)/0.10 = 176408 . . . > 1666.67
The required interest rate will be between 9% and 10%, option B.

What are complex numbers?Complex numbers are the numbers that are expressed in the form of
a + ib where, a, b are real numbers and 'i' is an imaginary number called “iota”. The value of i = ([tex]\sqrt{-1}[/tex]). For example, 2 + 3i is a complex number, where 2 is a real number (Re) and 3i is an imaginary number (Im).
From the graph we can know
[tex]Z_{1} (-5,2) = -5 +2i[/tex]
[tex]Z_{2} (5,2) = 5 +2i[/tex]
The difference between Z1 and Z2 is [tex]Z_{1} -Z_{2}[/tex]
[tex]Z_{1} -Z_{2}[/tex] = (-5 + 2i) - (5 + 2i)
= -5 + 2i - 5 - 2i
= -10 + 0i
[tex]Z_{1} -Z_{2}[/tex] locates on the real axis.
Option B is correct.

Mrs. Corn is making a turkey dinner. It is 22 pounds. It takes 20 minutes a pound to cook a stuffed turkey and 15 minutes a pound to cook an unstuffed turkey. How many more minutes does it take to cook a stuffed turkey than to cook one that is unstuffed?
Answer:
110 minutes
Step-by-step explanation:
Weight of turkey = 20 pounds
Time taken for a pound of stuffed turkey to get cooked = 20 minutes
Time taken for a pound of unstuffed turkey to get cooked = 15 minutes
Time taken for a 22 pound of stuffed turkey to get cooked = 20 × 22
= 440 minutes
Time taken for a 22 pound of unstuffed turkey to get cooked = 15 × 22
= 330 minutes
Difference of time to get cooked between a stuffed and unstuffed turkey = 440 - 330
= 110 minutes
110 more minutes are taken to cook a stuffed turkey than to cook one that is unstuffed.
