What is the gradient of the blue line?
X
Answer:
1/4
Step-by-step explanation:
Using points (0 ; 1) and (4 ; 2)
m= y2-y1 / x2-x1
= 2-1 /4-0
= 1/4
The gradient of the blue line is, 1/4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the blue line are (3, -3) and (3, -6).
Now,
Since, The equation of line passes through the points (4, 2) and (8, 3).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 2) / (8 - 4)
m = 1 / 4
m = 1/4
Thus, The gradient of the blue line is, 1/4

The prices of commodities X,Y,Z are respectively x, y, z, rupees per unit. Mr. A purchases 4 units of Z and sells 3 units of X and 5 units of Y. Mr. B purchases 3 units of Y and sells 2 units of X and 1 units of Z. Mr. C purchases 1 units of X and sells 4 units of Y and 6 units of Z.in this process A and C earn Rs. 6000 and Rs. 13000 respectively. While B neither lose nor gain. Find the prices per unit of the three commodities by using appropriate method.
please help me!!
Answer:
[tex](x,y,z)=(1477, 1464, 1437)[/tex]
Step-by-step explanation:
Consider the selling of the units positive earning and the purchasing of the units negative earning.
Case-1:Mr. A purchases 4 units of Z and sells 3 units of X and 5 units of YMr.A earns Rs6000So, the equation would be
[tex]3x + 5y - 4z = 6000[/tex]
Case-2:Mr. B purchases 3 units of Y and sells 2 units of X and 1 units of ZMr B neither lose nor gain meaning he has made 0₹hence,
[tex]2x - 3y + z = 0[/tex]
Case-3:Mr. C purchases 1 units of X and sells 4 units of Y and 6 units of ZMr.C earns 13000₹therefore,
[tex] - x + 4y + 6z = 13000[/tex]
Thus our system of equations is
[tex]\begin{cases}3x + 5y - 4z = 6000\\2x - 3y + z = 0\\ - x + 4y + 6z = 13000\end{cases}[/tex]
Solving the system of equations:
we will consider elimination method to solve the system of equations. To do so ,separate the equation in two parts which yields:
[tex]\begin{cases}3x + 5y - 4z = 6000\\2x - 3y + z = 0\end{cases}\\\begin{cases}2x - 3y + z = 0\\ - x + 4y + 6z = 13000\end{cases}[/tex]
Now solve the equation accordingly:
[tex]\implies\begin{cases}11x-7y=6000\\-13x+22y=13000\end{cases}[/tex]
Solving the equation for x and y yields:
[tex]\implies\begin{cases}x= \dfrac{223000}{151}\\\\y= \dfrac{221000}{151}\end{cases}[/tex]
plug in the value of x and y into 2x - 3y + z = 0 and simplify to get z. hence,
[tex]\implies z= \dfrac{217000}{151} [/tex]
Therefore,the prices of commodities X,Y,Z are respectively approximately 1477, 1464, 1437

The radius of a circle is 9 feet. What is the Area and the circumference of the circle?
Answer:
area is 254.34 circumference is 56.52
Step-by-step explanation:
To find the area you need to follow the formula r^2(pi)
so it would be 9x9x3.14 which is 254.34
to find circumference you need to find diameter which is double the radius (9x2) so the diameter is 18
To find circumference to need to do radius x pi
18x3.14 is 56.52

A cup of hot water is left out to cool. The water is currently 19°C above room temperature. If the heat difference decreases by 5% every minute, what will the difference be in 13 minutes?
Answer:
The difference will be 0.65 °C above room temperature after 13 minutes.
The difference in temperature in 13 minutes will be 6.65° C.
What is an expression?The expression is defined as the relations of the numbers and the variables combined together to form the equation by the use of mathematical algebraic symbols like equal greater than or less than.
Given that a cup of hot water is placed on the counter to cool. The temperature of the water is currently 19°C above room temperature. If the temperature difference falls by 5% every minute.
The heat difference will be calculated as:-
Total decrease = 13 x 5 = 65%
[tex]H = 19\times\dfrac{100-65}{100}[/tex]
[tex]H = 19\times \dfrac{35}{100}[/tex]
H = 19 x 0.35
H = 6.65°
Therefore, the temperature will be 6.65°.

Answer:
side: 17 inchesaltitude: 6 inchesStep-by-step explanation:
The formula for the area of a triangle gives a relationship between area, height, and base length. The problem statement gives the area, and it gives another relation between height and base length. Using these two relations, you can solve for the dimensions of the triangle.
__
setupThe side to which the altitude is measured is called the "base" in the area formula. The altitude is called the "height." The relation between them given by the area formula is ...
A = 1/2bh
51 = 1/2bh . . . . . . using the given value for area
The other relation given by the problem statement is that the base is 1 less than 3 times the height:
b = 3h -1 . . . . . . . base is 1 less than 3 times altitude
__
solutionUsing this second equation to substitute for 'b' in the first equation, we have ...
51 = 1/2(3h -1)h
102 = 3h² -h . . . . multiply by 2, eliminate parentheses
3h² -h -102 = 0 . . . . . put in standard form
3h² -18h +17h -102 = 0 . . . . . prepare to factor
3h(h -6) +17(h -6) = 0 . . . . . factor pairs of terms
(3h +17)(h -6) = 0 . . . . . . . . finish factoring
Solutions are the values of h that make these factors zero:
3h +17 = 0 ⇒ h = -17/3
h -6 = 0 ⇒ h = 6
We know that dimensions in a geometry problem must be positive, so the solution here is h = 6. Then b = 3h -1 = 3(6) -1 = 17. The dimensions are all in inches.
The length of the side is 17 inches; the altitude to that side is 6 inches.

Let's solve this problem step-by-step:
1. Let's put this in a fraction format:
6834 ÷ 17 = [tex]\frac{6834}{17}[/tex]
2. Now we know 6834 = 6800 + 34
⇒ so:
[tex]\frac{6834}{17} =\frac{6800+34}{17} =\frac{6800}{17} +\frac{34}{17}[/tex]
3. Now let's convert the fractions to denominators
[tex]\frac{6800}{17} +\frac{34}{17} =[/tex] (6800 ÷ 17) + (34 ÷ 17)
Let's check:
6834 ÷ 17 = 402(6800 ÷ 17) + (34 ÷ 17) = (400) + (2) = 400 + 2 = 402
Answer: (6800 ÷ 17) + (34 ÷ 17) or Choice (C)
