Answer:
Should be $300
let me know if it's correct:)
because 96 x 3 = 288
204 x 3 = 612
when you minus 288 - 612 the answer is 324 and the estimate is 300

what is the average rate of change from x equals negative 1 to x equals 1
Answers
Answer:
This question is incomplete, so I can not give you an exact answer, but I can give you the answer for the general case.
If we have a function f(x), the average rate of change between the values:
x = a and x = b,
is given by:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
So if we want to find the rate of change from:
x = -1 to x = 1
it is just:
[tex]r = \frac{f(1) - f(-1)}{1 - (-1)} = \frac{f(1) - f(-1)}{2}[/tex]
So just to show an example, if:
f(x) = 3*x^2 - 5
the average rate of change in that interval will be:
[tex]r = \frac{f(1) - f(-1)}{2} = \frac{3*1^2 - 5 - (3*(-1)^2 - 5)}{2} = \frac{-2 - (-2)}{2} = 0[/tex]
Jane and Tannic split the cost of buying a video game. The game costs$25, and the sales is 6% markup. How much do they each pay?
Answers
Given:
The cost of game = $25
Sales markup = 6%
To find:
How much do they each pay?
Solution:
The sales markup is 6% of the cost.
[tex]\text{Sales markup}=25\times \dfrac{6}{100}[/tex]
[tex]\text{Sales markup}=1.5[/tex]
Now, the total cost after sales markup is:
[tex]25+1.5=26.5[/tex]
Jane and Tannic split the cost of buying a video game. It means they divide the cost in two equal parts. So, the amount paid by each one is
[tex]\dfrac{26.5}{2}=13.25[/tex]
Therefore, Jane and Tannic will pay $13.25 each .

slope = 4, point (3,-2) is on the line
Answers
Answer:
y = 4x + b
Step-by-step explanation:
We know that (3, -2) is on this line. So 3 = m(-2)+b.
This leaves us with two variables the slope (m) and the y intercept (b).
But wait a minute, the slope is given to us since it says slope = 4.
Our equation is now, 3 = 4(-2)+b
3 = -8 + b
b = 11.
Our final equation is now y = 4x + b.
(y,x) is a point on this line.
Hope this helped!

A rod 123.75 cm long is sawn into 16 equal lengths. If a wastage takes place of ¼ cm for each saw cut, what is the length of each piece?
Answers
Answer:
7.5 cm
Step-by-step explanation:
A rod 123.75 cm long is sawn into 16 equal lengths.
The length of each rod is calculated as:
123.75cm/16 =
= 7.734375cm
If a wastage takes place of ¼ cm for each saw cut,
The length of each piece is calculated as:
7.734375cm - 1/4 cm
7.734375cm − 0.25 cm
7.484375cm
Approximately = 7.5 cm
Therefore, the length of each piece = 7.5 cm
If AD = 5.1cm, find the height (in cm) of the triangle.
Answers
Answer:
I. AC = 15 cm
II. h = 7.4 cm
Step-by-step explanation:
I. Determination of AC
AB = 9 cm
BC = 12 cm
AC =?
The length AC can be obtained by using pythagoras theory as illustrated below:
AC² = AB² + BC²
AC² = 9² + 12²
AC² = 81 + 144
AC² = 225
Take the square root of both side
AC = √225
AC = 15 cm
II. Determination of the height.
AB = 9 cm
AD = 5.1 cm
BD = h =?
The height of the triangle can be obtained by using pythagoras theory as illustrated below:
AB² = AD² + BD²
9² = 5.1² + h²
81 = 26.01 + h²
Collect like terms
h² = 81 – 26.01
h² = 54.99
Take the square root of
h = √54.99
h = 7.4 cm
Find the missing side of the triangle. Round your answers to the nearest tenth if necessary.

Answers
Answer:
Height is same for both the towers
Step-by-step explanation:
The computation is as follows;
For 1st tower
The height is
= 128 ÷ 4^2
= 8 inches
And,
For the 2nd tower
The height is
= 288 ÷ 6^2
= 8 inches
So as we can see that the height of the both the tower is same i.e. 8 inches so the same should be considered

Line q has a slope of -8/9 , Another line r has the slope of 9/8.Are line q and line r parallel or perpendicular?
Answers
Answer:
perpendicular
Step-by-step explanation:
parallel => both lines have the same value of slope
perpendicular => the product of both slope values are -1
=> -8/9 x 9/8 = -1
If Line q has a slope of -8/9 , Another line r has the slope of 9/8.Then both lines are perpendicular but not parallel
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Two lines are parallel when the slope of two lines is same, so 1 and r are not parallel.
Two lines are said to be perpendicular when the product of two slopes is minus 1.
Line q has a slope of -8/9
Let m₁=-8/9
r has the slope of 9/8
m₂=9/8
Now let us multiply m₁ and m₂
m₁ ×m₂
-8/9×9/8
-1
The product of slopes of q and r is -1. The lines are perpendicular.
Hence Line q and line r are perpendicular but not parallel.

Runelle collected river water for an experiment. She poured it into 8 jars. Each jar had the mixed number two and three fourths pints of water. What is the total amount of river water Runelle collected?
Answers
Answer: 22 pints of water
Step-by-step explanation:
Runelle collected river water and poured in eight jars such that each jar had 2³/₄ of water.
The total amount of water collected by Runelle from the river will therefore be the sum of all the water in the 8 jars and because they are the same, we can simply multiply the quantity in one jar by 8 to see the sum:
= Amount of water in one jar * 8 jars
= 2³/₄ * 8
= 11/4 * 8
= 22 pints of water

What is the slope given the two points?
(-3,12) & (4,5)
Answers
Answer:
-1
Step-by-step explanation:
(-3 , 12) & (4, 5)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{5 - 12}{4-[-3]}\\\\= \frac{-7}{4+3}\\\\=\frac{-7}{7}\\\\= -1[/tex]
Explanation:
Let, (-3,12) be (x1,y1) and (4,5) be (x2,y2)
We know that slope = (y2 - y1)/(x2 - x1)
So, slope of given two points = (5 - 12)/(4 - (-3))
= -7/(4+3)
= -7/7
= -1
Therefore, slope of given two points = -1
