If log103 ~ 0.4771,
evaluate log100.0003.
Give your answer to four decimal places.
WILL GIVE BRAINLIEST!!!
Answer:
Step-by-step explanation:
log₁₀0.0003 = log₁₀(3 × 10⁻⁴)
= log₁₀3 + log₁₀(10⁻⁴)
= log₁₀3 + (-4)
≈ 0.4771 - 4
= -3.5229
If the value of log₁₀3 is 0.4771. Then the value of the log₁₀0.0003 will be negative 3.5229.
What is a logarithm?Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.
The logarithm is given below.
log₁₀3 ≅ 0.4771
Then the value of log₁₀0.0003 will be
This can be written as
log₁₀0.0003 = log₁₀ (3 x 10⁻⁴)
We know the property of the logarithm, then we have
log₁₀ (ab) = log₁₀ a + log₁₀ b
log₁₀ aⁿ = n log₁₀ a
log₁₀ 10 = 1
Then we have
log₁₀ (3 x 10⁻⁴) = log₁₀ 3 + log₁₀ 10⁻⁴
log₁₀ (3 x 10⁻⁴) = 0.4771 - 4 log₁₀ 10
log₁₀ (3 x 10⁻⁴) = 0.4771 - 4 x 1
log₁₀ (3 x 10⁻⁴) = 0.4771 - 4
log₁₀ (3 x 10⁻⁴) = -3.5229

Answer:
A. 2/3
Step-by-step explanation:
Fraction is another way to divide , So in some math problems they want you to either flip the fraction or divide the numbers .
Option A is correct, the expression 2÷3 written as a fraction is 2/3.
What is Fraction?A fraction represents a part of a whole.
We have to write 2÷3 as a fraction.
Two divided by three.
We have to split the number two by three parts.
We know that any division expression can be written as a fraction, the numerator is a part and denominator is a whole.
Two is the numerator and three is the denominator.
The numerator represents the part and three represents the whole.
This we can write in fraction as 2/3.
Two by three is the fraction form of two divided by three.

The population of a city increases by 1.5% per year. If this year's population is
288,000, what will next year's population be, to the nearest individual?
Answer: 292,320
Step-by-step explanation:
Find the increase, 1.5% of 288,000:
1.5/100 = 0.015
288,000 * 0.015= 4,320
Add the increase to the current population:
288,000+4,320= 292,320
What are the dependent and independent
variables?
Answer:
The dependent variable depends on the value of some other number also known as the independent variable. Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5.

A school club spends $75 on supplies to set up a car wash fundraiser. The students are going to charge $6.00 per car. Write a linear model in the form y=mx+b where y represents the amount of profit the students earn for washing x number of cars.
Answer:
Y=6x-75
Step-by-step explanation:
If you take the beginning amount spent which is $75 you would want that on the graph to be in the negatives. With it starting in the negatives it will show you whether the amount of cars (x) will cause a profit or a deficit.
For instance, say they washed 7 cars (x=7). You would take 6 and multiply it by 7 to get 42. Then you would take 42 and take away 75 to find the profit/deficit. 42-75= -33
This shows that washing 7 cars will cause them to lose $33.
If you take another situation where they wash 15 cars (x=15). In this case they would earn a total of $15.
Find the area of the composite figure
Area of the triangle=
Area of rectangle A=
Area of rectangle B=
Total Area of composite=
Answer:
Area of the triangle = 31.25 yd²
Area of rectangle A = 50 yd²
Area of rectangle B = 48.75
Total Area of composite = 130 yd²
Step-by-step explanation:
✔️Area of the triangle = ½*b*h
b = 10 yd
h = 6.25 yd
Area of the triangle = ½*10*6.25 = 31.25 yd²
✔️Area of rectangle A = L*W
L = 10 yd
W = 7.5 - 2.5 = 5yd
Area of rectangle A = 10*5 = 50 yd²
✔️Area of rectangle B = L*W
L = 7.5 yd
W = 6.5 yd
Area of rectangle B = 7.5*6.5 = 48.75 yd²
✔️Total Area of Composite = 31.25 + 50 + 48.75 = 130 yd²

The Rileys are buying a home that costs $250,000. They are paying 3% in closing costs and 12% for a down payment. Complete the statement. The Rileys will pay a total of in costs for the closing costs and down payment on their mortgage.
Answer:
37,500 and non recurring
Step-by-step explanation:
The Riley's will pay a total of $7,500 in costs for the closing costs and $30,000 down payment on their mortgage.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Rileys are buying a home that costs $250,000.
12% for a down payment
So, down payment is
12% of 250,000
= 12/100 ×250,000
= 12×2500
= $30,000
They are paying 3% in closing costs
3% of 250,000
= 3/100×250,000
= $7,500
Therefore, the Riley's will pay a total of $7,500 in costs for the closing costs and $30,000 down payment on their mortgage.

what is the answer of 3x+235+237
Answer:
3x + 472
Step-by-step explanation:
Answer:
3x + 472
Step-by-step explanation:
We have the expression 3x + 235 + 237 and are asked to find the answer.
We are not solving for x, neither are we doing anything complicated, we need to focus on like terms, which are certain numbers having different symbols, in which they can only be added with the numbers with the same symbols as them.
In this equation, we have two terms, variables and constant. We can only add the constants because once again, you cannot add two terms that don't have the same symbol.
Therefore :
3x + 235 + 237
235 + 237
472.
The answer is 3x + 472
