Answer:
12. -11
13. 2
Step-by-step explanation:
12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction
For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.
From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.
Your new equation is -10-8+7 = -11
13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))
keep in mind there’s an addition between the twoDivision and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17
Second multiply 5 x -3 = -15
Now you can combine the two answers using addition: 17 + (-15) = 2
what is the perimeter of PQR with vertices P(-2, 9), Q(7, -3) R(-2, -3) in the coordinate plane?
Answer:
[tex]p (perimeter) = 36[/tex]
Answer:
36.
Step-by-step explanation:
The perimeter = PQ + QR + RP
= √[(-2 -7 )^2 + (9- (-3))^2)] + √[(7 - (-2))^2 + (-3 - (-3)^2)] + √((-2 -(-2)^2+(-3-9)^2)]
= √(81+144) + √81 + √144
= √225 + √81 + √144
= 15 + 9 + 12

6. Find the equation of the line perpendicular to y=2 through (1,5). * A. y 2 B.X D.X=2 耕
Answer:
Step-by-step explanation:
To convert the measurements of metric system into another units of metric system we have to either multiply it by 10, 100, 1000, 10000, 100000, etc or divide by 10, 100, 1000, 10000, 100000, etc.
If we have to convert bigger unit into smaller unit then we have to multiply the unit by the multiples of 10, then the decimal point is shifted to right by 1 or 2 or 3 or 4 , etc. places.
For example, 1.2 kg is converted into g so we have to multiply it by 1000, so decimal point is shifted to right by 3 places, i.e.,
1.2 x 1000 = 1200 g
If we have to convert smaller unit into bigger unit then we have to divide the unit by the multiples of 10, then the decimal point is shifted to left by 1 or 2 or 3 or 4 , etc. places.
For example, 12 cm is converted into m so we have to divide it by 100, so decimal point is shifted to left by 2 places, i.e.,
12 / 100 = 0.12 m

Skye wants to buy 3 erasers each for her 4 best friends. If erasers cost $0.72 each, how much money does Skye need?
Answer:
3 x 4 = 12 erasers 12 x $0.72 = $8.64
Step-by-step explanation:
Answer: Skye will need $8.64
Step-by-step explanation:
We can start by seeing how many erasers she needs in total. We can multiply the 3 erasers for all 4 of her friends.
3 x 4 = 12 Erasers
Now we multiply the cost of one eraser by the total amount she needs, 12.
0.72 x 12 = 8.64
So the amount of money Skye needs for all her friends to have 3 erasers is $8.64

Divide (long division)
(4n^4+4n^3+16n^2)+4^2
9514 1404 393
Answer:
n^2 +n +4
Step-by-step explanation:
Since the divisor has only one term, the quotient is formed by dividing the terms one at a time.
[tex]\dfrac{4n^4+4n^3+16n^2}{4n^2}=\dfrac{4n^4}{4n^2}+\dfrac{4n^3}{4n^2}+\dfrac{16n^2}{4n^2}=\boxed{n^2 +n +4}[/tex]
__
Your long division tableau will subtract n^2×4n^2 = 4n^4 to form the new dividend 4n^3+16n^2. Then you will subtract n×4n^2 = 4n^3 to get the new dividend of 16n^2. The final quotient term is 4, and you will subtract 4×4n^2 to get a remainder of 0. You will have written the quotient as n^2+n+4.
A car travels at a constant speed of 20m/s.Work out the distance travelled [in meters] by the car after (a) 4seconds (b) 12seconds (c) 3mins (d) 2hrs
Answer:
This is quite an easy question u should try it yourself
Step-by-step explanation:
The formula is
V= d / t
Therefore the distance is
D = vt
So since they alredy gave u that v = 20m/s

what is (-11/21)+9/21 simplified
Explanation:
Ignore the denominators for now.
The numerators -11 and 9 add up to -11+9 = -2
Then we place that result over the common denominator 21 to get the final answer -2/21
This trick only works if the denominators are all the same. If not, then you'll need to find the LCD first before you can add the fractions. Luckily, all of the denominators were the same at 21.
(-11/21)+9/21
= (-11+9)/21
= -2/21.ans...

h=54+1/2at^2 solve for a
Im lost on if I should square the 1/2at first?
Other answer formats are possible.
===========================================================
Explanation:
Let's say we want to solve the equation h = 54 + 10a for the variable 'a'. This is relevant to the problem at hand don't worry.
What we'd do is two things
Subtract 54 from both sides Divide by 10So the steps look like this
h = 54 + 10a
h-54 = 10a
(h-54)/10 = a
a = (h-54)/10
Now let's say we wanted to solve this equation: h = 54 + ca, where c is a constant and can stand in place of any number. The steps would be pretty much identical. Instead of dividing both sides by 10, we divide both sides by c. We can do this as long as c isn't zero of course.
That means the equation h = 54+ca solves to a = (h-54)/c
---------------------------
Why did I do those examples? To build up to the equation your teacher gave you.
Let's replace c with 0.5t^2
This is because 1/2 = 0.5
The 1/2at^2 is the same as (1/2t^2)a
So instead of a = (h-54)/c, we'd get a = (h-54)/(0.5t^2)
As a last optional and encouraged step, we can multiply every term by 2 to get rid of that decimal value.
Doing so makes a = (h-54)/(0.5t^2) turn into a = (2h-108)/(t^2)
---------------------------
Here's another way to solve:
h = 54 + (1/2)at^2
h-54 = (1/2)at^2
2(h-54) = at^2
2h-108 = at^2
(2h-108)/(t^2) = a
a = (2h-108)/(t^2)
In the second step, I subtracted 54 from both sides. Immediately afterward, I multiplied both sides by 2 so I could clear out the fraction. Then I divided both sides by t^2 to fully isolated the variable 'a'.
