It depends but it's most like a A.
I'd say a 98/99% is an A+
Answer:
A 92% on any exam would just be an A, because it's closer to a 90% than an 100%.
Step-by-step explanation:
If it's a 95% or higher, then you can consider that an A+.

Answer:
x=8
Step-by-step explanation:
9(8)+12= 84 which makes the other angel of the traingle 96. 7(8)+6 is equal to 62. Adding 62 with 22 and 96 gives you 180, making the traingle complete. Hope this helps :)
Answer:
x = 8
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
9x + 12 is an exterior angle of the triangle , then
9x + 12 = 7x + 6 + 22
9x + 12 = 7x + 28 ( subtract 7x from both sides )
2x + 12 = 28 ( subtract 12 from both sides )
2x = 16 ( divide both sides by 2 )
x = 8

The roots of the quadratic function describing the relationship between number of
products produced and overall profit margin are x = 0 and 28. The vertex is a minimum
at (14, -40)
The company actually loses money on their first few products as it costs them more to
make them, but once they hit items they break even again.
The worst case scenario is that they produce items, as they will have a profit of
dollars. The first root tells us that the profit will be 0 when products are
sold.

Find the value or expression for 0.
1. sin(55) = cos( )
2. sin ( ) = cos(28)
3. cos(y) = sin( )
Using complementary angles, it is found that the values for the expressions are given as follows:
1. sin(55) = cos(35).
2. sin (62) = cos(28).
3. cos(y) = sin(90 - y).
What are complementary angles?
Two angles are called complementary if the sum of their measures is of 90º; If two angles are complementary, the sine of one is the cosine of the other.
Hence, since 55 + 35 = 62 + 28 = 90, we have that the values are given as follows:
1. sin(55) = cos(35).
2. sin (62) = cos(28).
3. cos(y) = sin(90 - y).

Answer:
12
Step-by-step explanation:
(x / 2) + 4 = 10
(x + 2 * 4 ) / 2 = 10
x + 8 = 20
x = 20 - 8
x = 12
or just
x /2 = 10 -4 = 6
x = 6 * 2 = 12
Answer:
x = 12
Step-by-step explanation:
First multiply everything by 2 getting x alone giving you x + 8 = 20 then move 8 to the other side giving you x = 20 - 8 and then subtract giving you x = 12
At the local dairy farm, Kareem buys a 32-oz container of yogurt for $2.56. Jonah buys a 6-oz container of yogurt for $0.48. Are the cost, y, in dollars and the amount of yogurt, x, proportional? Explain. Write an equation to represent this relationship.
Answer:
The ratios 2.56/32 and 0.48/6 are equivalent; y = 0.08x.
Step-by-step explanation:
$2.56 for 32 oz is a unit price of $2.56/(32 oz) = $0.08/oz
$0.48 for 6 oz is a unit price of $0.48/(6 oz) = $0.08/oz
The unit prices are equal, so the cost of both sizes are proportional.
If x is the weight in oz, multiply the weight by 0.08 to get the cost, y, in dollars.
y = 0.08x
The ratios 2.56/32 and 0.48/6 are equivalent; y = 0.08x.

The graph of a linear equation contains the points (6,7) and (-4,13) find another point that lies on the graph
Answer:
(10,4.6)
Step-by-step explanation:
We need to find the equation for the line first
Find the slope:
m = y2-y1/x2-x1
m = 13 - 7 / -4 - 6
m = 6 / -10
Now we need the y intercept (b)
subtitute one of the points into the equation
y = -6/10x + b
7 = -6/10(6) + b
7 = -3.6 + b
10.6 = b
Now we have the full equation for the line
y = -6/10x + 10.6
and we can input any value into x to find the y of the point
y = -6/10(10) + 10.6
y = -6 + 10.6
y = 4.6
Answer:
(11, 4)
Step-by-step explanation:
Find the slope = rise/ run or (change in y values)/(change in x-values)
Using points (6, 7) and (-4, 13) ; Slope = (13 - 7)/(-4 - 6) = 6/-10 = -3/5
From this point if the slope is -3/5 this means the rise is -3 and the run 5.
remember that a negative rise you will move down on the rise from the point and a positive run means you will move across from the point.
Using point (6, 7) .
The run is the x movement on a graph so start at 6 and move to the right 5 places, you in up at x= 11.
The rise is the y movement on the graph so start at 7 and move down 3 places, you are at y = 4
Point (x, y) on the graph is (11, 4)
to check the problem
you from the slope = -3/5 . If you solve for "b" in y = mx + b. The equation of the line in slope intercept form is y = -3/5x + 53/5. Graph the line and check the point or substitute any value for x and solve for y.

Ann went to the bakery, she bought a cake for $15.88,
5 cookies for $.55 each and a dozen doughnuts for $.85 each.
How much did she spend in all
Answer:
$27.83
Step-by-step explanation:
15.88+5(.55)+12(.85)=28.83
Answer:
Ann spent $28.83.
Why?
We can find the answer by just multiplying the prices of cookies and doughnuts by their amounts, and adding the total prices together. 0.55 x 5 = $2.75, 0.85 x 12 = $10.20. 2.75 + 10.20 + 15.88 = 28.83. Therefore, Ann spent $28.83.

The teacher separated her class of twentyeight students into two groups. One group has 4 more than twice as many students as the other group. How many students are in each group
Answer:
The first group has 20 and the second group has 8.
Step-by-step explanation:
1. Twice as many as 8 is 16 (8x2)
2. If you add four to the total it's 20 (16+4=20)
3. So group one has four more than twice as many as group 2.
The number of students in a school is between 500 and 600. If we group them into groups of 12, 20, or 36 each, 7 students are always left over. How many students are in this school?
There are 547 students in this school.
How did we arrive at the value?Let's solve this problem step by step.
1. We know that the number of students is between 500 and 600 and leaves a remainder of 7 when divided by 12, 20, or 36.
2. To find the number of students, we need to find a number that satisfies all these conditions.
3. Let's start by finding the least common multiple (LCM) of 12, 20, and 36, which is 180.
4. Now, we can represent the number of students as 180n + 7, where n is a positive integer.
5. To find a value of n that falls within the range of 500 to 600, we can try different values for n until we get a suitable number.
Let's calculate:
For n = 3: 180 * 3 + 7 = 547 (Within the range)
For n = 4: 180 * 4 + 7 = 727 (Exceeds the range)
So, there are 547 students in this school.

Ebony has her bank account opened for 1 week and the graph shows the entire week. During that time, her greatest balance was $300.
a) Give the domain of the function.
b) Give the range of the function.
Using it's concepts, the domain and the range of the function are given as follows:
a) Domain: [0, 7].
b) Range: [0, 300].
What are the domain and the range of the function?The domain of a function is composed by the set of all possible input values of the function. Hence, on the graph, the domain is composed by the values of x.
In the context of this problem, the input of the function is the number of days. A week has 7 days, hence the domain of the function is given by:
[0, 7].
The range of a function is composed by the set of all possible output values of the function. Hence, on the graph, the range is composed by the values of y.
In the context of this problem, the output of the function is the balance of the bank account after each day. Supposing that the smallest balance of the account is of $0, and considering the greatest balance of $300 stated in the problem, the range of the function is given by:
[0, 300].
What is the missing information?The graph of the function is incomplete, hence we suppose that the minimum balance is of $0.

Round the following numbers to the nearest 100. 468 1350 6849
The solution is, rounding off the numbers to the nearest 100. 468 1350 6849, is: 500, 1300, 6800.
What is round off?Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
here, we have,
given that,
the numbers are 468, 1350, 6849
now, we have to Round the following numbers to the nearest 100.
To round a number to the nearest 100, look at the tens digit. If the tens digit is 5 or more, round up. If the tens digit is 4 or less, round down.
so, we get,
468 => 6>5, so, 468 =>500
1350 => 35 < 50, so 1350 => 1300
6849 => 4<5 , so , 6849=> 6800
Hence, The solution is, rounding off the numbers to the nearest 100. 468 1350 6849, is: 500, 1300, 6800.
