Answer:
72.624 kg
Step-by-step explanation:
1g = 0.001 kg
104g = 0.104kg
weight of 1 bag = 12.104kg
weight of 6 bags = 12.104 x 6
weight of 6 bags = 72.624kg
The pH of solution measures its acidity and can be determined using the formula pH= -log(base of 10 )C, where is the concentration of hydronium ions in the solution. measured in moles per litre .A lower pH indicates a more acidic solution.
The concentration of Hydronium ions type of coffes is 1.3 x 10above-5 moles per liter .
Calculate the pH of the coffee.
The value of pH of the coffee is 4.89
How to determine the pH of the coffee?pH is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution
Given: The formula pH= -log₁₀ C,
where is the concentration of hydronium ions in the solution measured in moles per litre
The concentration(C) of Hydronium ions type of coffee is 1.3 x 10⁻⁵ moles per liter
To calculate the pH, we will substitute the value of the concentration (C) into the given formula:
pH= -log₁₀ C (C = 1.3 x 10⁻⁵ moles per liter)
pH = -log₁₀(1.3 x 10⁻⁵) = 4.89
Therefore, the pH of the coffee is 4.89

Your friend uses the figure to say that all the exterior angles of any isosceles triangle are congruent. Is your friend correct? Explain your reasoning
Answer:
All the exterior angles of any isosceles triangle are congruent - FALSE statementStep-by-step explanation:
We know that the exterior angle of a triangle is the sum of remote interior angles.
If the triangle is equilateral then the sum of any two interior angles is same otherwise, with any isosceles triangle, we get different sums and therefore the friend is wrong.
Answer:
No.
Step-by-step explanation:
An isosceles triangle has two sides of equal length. Therefore, only two of its interior angles are congruent.
The exterior angle of a triangle is equal to the sum of the two opposite interior angles (remote interior angles). Therefore, as not all of the three interior angles of an isosceles triangle are congruent, all the exterior angles will also not be congruent.

The equation of the transformation of the exponential function y = 2ˣ in the form y = A·2ˣ + k, obtained from the simultaneous found using the points on the graph is y = (-2)·2ˣ + 3
What is an exponential equation?An exponential equation is an equation that has exponents that consists of variables.
The given equation is y = 2ˣ
The equation for the transformation is; y = A·2ˣ + k
The points on the graphs are;
(0, 1), (1, -1) and (2, -5)
Plugging the x and y-values to find the value A and k gives the following simultaneous equations;
When x = 0, y = 1, therefore;
1 = A·2⁰ + k = A + k
1 = A + k...(1)
When x = 1, y = -1, which gives;
-1 = A·2¹ + k
-1 = 2·A + k...(2)
Subtracting equation (1) from equation (2) gives;
-1 - 1 = 2·A - A + k - k
-2 = A
1 = A + k, therefore;
1 = -2 + k
k = 2 + 1 = 3
k = 3
Which gives;
y = -2·2ˣ + 3 = 3 - 2·2ˣ

What is multiplication?
A mathematical formula that specifies the objects to be multiplied, known as a factor, produces a product. For instance, the product of 6 and 5 is 30.
Given: The operation * is defined as,
a*b = a + b - 2ab
We have to find the value of 2*(3*5) and (2*3)*5

The box must be added with 7 cubic feet of sand
What is volume?Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also be defined as the capacity of an object.
It is measured in cubic units.
The volume of a box is length × width × height
represent the original length, width and height by x ,y ,z respectively
This shows that the volume of the original box= x× y× z = 1cubic foot
when the original length, width and height are doubled to give the new dimensions
Therefore the new length,width and height will be 2x, 2y and 2z
the volume of the new formed box = 2x×2y×2z
= 8xyz

We have to calculate the monthly payment P for a $75,000 loan with a 20-year term (n = 240 months) and an annual interest rate of 4% (let r=.9967).
We know that,
Formula for monthly payment is P(i(1+i)ⁿ/(1+i)ⁿ-1)
Here,
P is principal amount $75,000
n is number of months 240 months
i is interest rate 4% is 0.04
=P(i(1+i)ⁿ/(1+i)ⁿ-1)
