Step-by-step explanation:
The percent change from 45 to 90 is
A change from 45 to 90 represents a positive change (increase) of 100%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old|Old| × 100%
Percent change = 90 - 45|45| × 100% =
4545 × 100 = 100% (increase)
Where: 45 is the old value and 90 is the new value. In this case we have a positive change (increase) of 100 percent because the new value is greater than the old value.

Answer:
? = 13
Step-by-step explanation:
40.5/9 = 4.5
9 x 4.5 = 40.5
X x 4.5 = 58.5
4.5X = 58.5
4.5X/4.5 = 58.5/4.5
x = 13
Answer:
13
Step-by-step explanation:
We are given the sides of one of the triangles. If you take 9/40.5, you get .2222222. We can then use that to find the base. If you take 58.5, multiply it by .22222, you get 13!

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.

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.

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
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.

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.

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.

SOMONE EXPLAIN CALCULUS TO MEEEE
Answer:
Calculus is when you make that amount of time tinier and tinier and tinier, and that makes the distance tinier and tinier and tinier too, so that, at that moment, the tiny distance divided by the tiny time is 31 miles per hour, but a second later it might be 30 mph or 32 mph or something else.
Step-by-step explanation:
Calculus is a branch of mathematics that involves the study of rates of change. ... Calculus helped to determine how particles, stars, and matter actually move and change in real time. Calculus is used in a multitude of fields that you wouldn't ordinarily think would make use of its concepts.
Categories
It has two major branches, differential calculus and integral calculus; the former concerns instantaneous rates of change, and the slopes of curves, while integral calculus concerns accumulation of quantities, and areas under or between curves.

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).
