=13+18-3
=31-3
=28
the answer is 28
Answer:
28
Step-by-step explanation:
According to Order of Operations rules, we must multiply here before adding or subtracting.
In 7 +6 - 9(-2) + (-3) the very first thing we must do is to evaluate the product -9(-2). This comes out to 18, so now we have:
7+6 + 18 +(-3).
Next, remove the remaining parentheses, obtaining:
7 + 6 + 18 - 3, or
13 + 15 = 28

What is the measure of angle A?
(x + 15)
Enter your answer in the box
mZA=
Answer:
<A = 133degrees
Step-by-step explanation:
Find the diagram attached
Using the theorem that "the sum of opposite angle of a cyclic quadilateral is 180 degrees, hence;
m<A + m<C = 180
4x+5 + x + 15 = 180
4x+x+5+15 = 180
5x+20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32degrees
Get the measure of angle A
<A = 4x+5
<A = 4(32)+5
<A = 128+5
<A = 133degrees

Answer:
44 degree
Step-by-step explanation:

Help me you will get the brain thing I need help with number 1
Answer:
A = (5, 4)
B = (4, 3)
C = (5, 2)
D = (6, 3)
Step-by-step explanation:
Before I do anything, I will write the figure's coordinates for ABCD
A = (2, 3)
B = (1, 2)
C = (2, 1)
D = (3, 2)
Now, a translation means adding and or subtracting the x and y coordinates within the ordered pairs.
3 units right means add 3 units to the value of coordinate x. Coordinate x will always be for any horizontal movement (left and right).
1 unit up means add 1 unit to the value of coordinate y. Coordinate y will always be for any vertical movement (up and down).
Make these adjustments to each ordered pair:
A = (2 + 3, 3 + 1)
A = (5, 4)
B = (1 + 3, 2 + 1)
B = (4, 3)
C = (2 + 3, 1 + 1)
C = (5, 2)
D = (3 + 3, 2 + 1)
D = (6, 3)
Unfortunately I cannot graph the points for you, but if you mark each ordered pair I've given and then connect them together with lines, it will be graphed.

The value of a car with an initial purchase price of $15,250 depreciates by 16% per year. How much is the car worth after 6 years? Find f(6):
a=15,250
r=0.016
x=6
Please correct me if my rate is wrong please provide the work.
Answer:
$13842.43
Step-by-step explanation:
Given data
Value of car=$15,250
Rate of depreciation= 16%
Time = 6 years
We can use the exponential function below to model the value of the car after 6 years
v(t)= a(r)^x
But r= 1-0.016----------Because the value is depreciating
a=15,250
r=0.016
x=6
Substitute
v(t)= 15250(1-0.016)^6
v(t)= 15250(0.984)^6
v(t)= 15250*0.9077
v(t)= $13842.43
Hence the value will be $13842.43 after 6 years

Step-by-step explanation:
Which is an example of a quadratic function whose graph opens downward and has its vertex at (0, 1)?
A. y = −x^2 + 1
B. y = x^2 + x − 1
C. y = x^2 + 4x + 1
D. y = x^2 − 1
Given:
The graph of a quadratic function opens downward and has its vertex at (0, 1).
To find:
The quadratic function.
Solution:
The vertex form of a quadratic function is:
[tex]y=a(x-h)^2+k[/tex] ...(i)
Where, a is a constant and (h,k) is the vertex.
If a<0, then graph opens downward and if a>0, then graph opens upward.
It is given that the quadratic function opens downward and has its vertex at (0, 1). It means a must be negative.
Putting h=0 and k=1 in (i), we get
[tex]y=a(x-0)^2+1[/tex]
[tex]y=ax^2+1[/tex]
For [tex]a=-1[/tex],
[tex]y=(-1)x^2+1[/tex]
[tex]y=x^2+1[/tex]
So, option A is correct.
In other options the leading coefficient is positive it means their graphs open upward. So, options B, C and D are incorrect.
Therefore, the correct option is A.

Answer:
1260
Step-by-step explanation:
12/72 is 1/6 of the students going to the play
210 students go to play
210 times 6 is 1260
Answer:
1260 students
Step-by-step explanation:
Let x be the number of students in the school.
12 of the 72 students surveyed said they would attend the school pay so
(12/72)x=(1/6)x gives the predicted number of ticket sales. (Here 12*6=72 so it becomes 1/6)
The table shows 210 students purchased tickets so( 1/6)x=210
x=6*210
x=1260 students attend the school.
Cash Orcheck had a balance of $867 in his checking account on
January 1. During January, Cash wrote checks for the following
amounts: $98. $456, $29, and $381. What was his balance at the
end of January?
Answer:
Well since he wrote the amount, he’s technically giving cash away so you basically jsut add everything.
98+456+29+381= 964
867-964= -97
His final balance would be -97
Here’s the thing, a checking account acts like a debit card. Its your own cold hard cash. That means you can’t give away more then you have.
So here are the two options
1) At least one or at most 2 checks must’ve bounced
2) He got more money in his checking account
You deposit money in an account that pays 5% interest compounded yearly. Find the balance after 5 years for the given initial amount (This is not multiple choice, you need to do a, b, and c)
a. $250
b. $300
c. $350

Answer:
X=47.68degree
Step-by-step explanation:
tanx=56/51
x=tan^(-1)(56/51)
=47.68
Answer:
What do we know?
SOH CAH TOA
SOH stands for opposite + hypotenuse
CAH stands for adjacent + hypotenuse
TOA stands for opposite + hypotenuse
We know from above: the opposite and the hypotenuse
tanx=56/51
x=tan^(-1)(56/51)
=47.68

Answer:
points (8, 0) and (3, 0)
Step-by-step explanation:
Here we're being asked to find the roots of this quadratic equation.
Set f(x) = 3(x² - 11x + 24 = 0.
This factors into f(x) = 3(x - 8)(x - 3) = 0.
Then x - 8 = 0 and x - 3 = 0, yielding x = 8 and x = 3. These correspond to the points (8, 0) and (3, 0).
Nancy goes to the Post Office to exchange money.
Exchange Rates
£1:$1.31
£1 : €1.14
*Commission Charged
$ £ €
Nancy changes $759.80 and €342 into pounds sterling.
The Post Office deducts their commission and gives Nancy £827.20
What is the percentage commission?
Answer:
6% commission
Step-by-step explanation:
Exchange Rates
£1:$1.31
£1 : €1.14
$759.80 to pounds sterling :
£1 = $1.31
x = $759.80
Cross multiply :
x = 759.80 / 1.31
x = £580
£1 = €1.14
x = €342
Cross multiply :
x = 342 /1.14
x = £300
Total = £(580 + 300) = £880
Amount deducted = commision = £880 - £827.20 = £52.80
Percentage commission :
(52.80 / 880) * 100%
0.06 * 100%
= 6% commission

A and b are positive integers and a-b=2. Evaluate the following:
(27^1/3b)/ ( 9^1/2a)
(this is urgent)
(I have tried 1, 25, and 1/27. None of them are correct)
Answer:
[tex]\displaystyle\displaystyle \frac{27^{1/3b}}{9^{1/2a}}=\frac{1}{9}[/tex]
Step-by-step explanation:
We are given that a and b are positive integers such that:
[tex]a-b=2[/tex]
And we want to evaluate:
[tex]\displaystyle \frac{27^{1/3b}}{9^{1/2a}}[/tex]
First, note that 27 = 3³ and that 9 = 3². Therefore:
[tex]\displaystyle =\frac{(3^3)^{1/3b}}{(3^2)^{1/2a}}[/tex]
Simplify:
[tex]=\displaystyle \frac{3^b}{3^a}[/tex]
Using the quotient property of exponents:
[tex]=3^{b-a}[/tex]
From our given equation, we can divide both sides by -1 to acquire:
[tex]-a+b=-2\text{ or } b-a=-2[/tex]
Therefore:
[tex]=3^{-2}[/tex]
Hence, our answer is:
[tex]\displaystyle\displaystyle \frac{27^{1/3b}}{9^{1/2a}} =\frac{1}{3^2}=\frac{1}{9}[/tex]

how do you write 3,901.25 as a scientific notation?
Answer: 3.90125×10⁻³
Step-by-step explanation:
The scientific notation consists of two parts
the number based: a, where 0<a<10the exponent based: 10ˣ, which is determined by how we change the number based "a"So the final version should be: a×10ˣ
-------------------------------------------------------------------
STEP ONE. Number based
We are given 3,901.25
In order to make it within the range of a, we should move the decimal to the left three places, or divide the number by 10³, which is times 10⁻³
We get 3.90125
STEP TWO: Exponent based
Since we changed the number by 10⁻³, this will be our exponent-based.
Therefore, it is 3.90125×10⁻³
Hope this helps!! :)
