Answer: -7/2
Using multiplication, the equation has the solution is -7/2.
What is multiplication?
The multiplication is "the process of multiplying one number is to multiply to its certain number of times".
According to the question,
[tex]\frac{8}{x} + 3 = \frac{1}{x} +1[/tex]
[tex]\frac{(8+3x)}{x} = \frac{1+x}{x}[/tex]
8 + 3x = 1 + x [By cancel 'x' on both denominator]
8 - 1 = x - 3x
7 = -2x
x = - [tex]\frac{7}{2}[/tex]
Hence, using multiplication the equation has the solution is -7/2.

Find the surface area of the cube for 1/4
Answer:
6a^2Step-by-step explanation:
This is the answer
"To find the surface area of a cube, use the formula: surface area = 6s^2, where s is the length of one of the sides. If you don't know the length of the sides, you can find the surface area using volume. Just find the cube root of the volume, which is equal to the length of one side of the cube."
Hope this helps!A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 35% salt and Solution B is 80%
salt. She wants to obtain 90 ounces of a mixture that is 40% salt. How many ounces of each solution should she use?
Solution A:
Solution B:
Answer:
80? bc yhu cant use solution a because it only has 35...i think
Step-by-step explanation:
if im wrong sorry
The requried scientist should use 80 ounces of Solution A (35% salt) and 10 ounces of Solution B (80% salt) to obtain a 90-ounce mixture that is 40% salt.
Let's assume the scientist uses x ounces of Solution A and y ounces of Solution B to obtain the desired mixture.
From the information given, we can set up the following equations:
Equation 1: The total amount of solution is 90 ounces, x + y = 90
Equation 2: The amount of salt in the mixture can be expressed as, 0.35x + 0.80y = 0.40 * 90
Simplifying Equation 2:
0.35x + 0.80y = 36
To solve these equations, we can use substitution or elimination. Let's use the substitution method.
From Equation 1, we can express x = 90 - y and substitute it into Equation 2:
0.35(90 - y) + 0.80y = 36
31.5 - 0.35y + 0.80y = 360
45y = 4.5y = 10
Substituting y = 10 back into Equation 1:
x + 10 = 90
x = 80
Therefore, the scientist should use 80 ounces of Solution A (35% salt) and 10 ounces of Solution B (80% salt) to obtain a 90-ounce mixture that is 40% salt.

Answer:
would be 4cm x 4 cm = 16 sq.cm. 6 surfaces of the cube would be 6 x 16 = 96 sq.cm. By definition, a cube has congruent sides. So, each side has an area A = s^2.
Step-by-step explanation:
hope this helps
The total surface area of the cube is 96 square centimeters.
We have,
Given that each side of the cube measures 4 cm, the formula to calculate the surface area is:
Surface Area = 6 * (side length)²
Substituting the value of the side length,
Surface Area = 6 * (4 cm)²
Surface Area = 6 * 16 cm²
Surface Area = 96 cm²
Therefore,
The total surface area of the cube is 96 square centimeters.

In a lab, a colony of 100 bacteria is placed on a petri dish. The population triples every hour.
1. How would you estimate the population of bacteria in. Make the minutes into a decimal and tell me what to substitute. Be specific on what you would do
a. 90 minutes?
b. 30 minutes?
2. How would you estimate the number of hours it would take the population to grow to 1,000 bacteria. Be specific on what you would do.
Reply as answers 1a, 1b, 2.
Answer:
1.a 519.615
1.b 173.21
2. It would take approximately 2.1 minutes
Step-by-step explanation:
If the population triples every hour then after one hour the population must be:
population(0) = 100
population(1) = 100*3 = population(0)*3
After two hours:
population(2) = population(1)*3 = population(0)*3*3 = population(0)*3²
After three hours:
population(3) = population(2)*3 = population(0)*3²*3 = population(0)*3³
Therefore the equation that will model the growth of the population is:
population(n) = 100*3^n
1. a.
We first need to convert the time from minutes to hours, to do that we must divide by 60. We have:
time = 90/60 = 1.5
We then apply this value in the "n" from the equation above:
population(1.5) = 100*3^(1.5) = 519.615
1.b.
We have to follow the same steps as before:
time = 30/60 = 0.5
population(0.5) = 100*3^(0.5) = 173.21
2.
We now use the same equation as before, but we want to solve for n isntead of "population". We have:
1000 = 100*(3^n)
100*(3^n) = 1000
3^n = 1000/100
3^n = 10
ln(3^n) = ln(10)
n*ln(3) = ln(10)
n = ln(10)/ln(3) = 2.095
It would take approximately 2.1 minutes
