Note: Consider the base of all is 3 instead of comma.
Given:
Consider the given value is [tex]\log_37=1.77[/tex].
To find:
The value of [tex]\log_363[/tex].
Solution:
Using properties of logarithm, we get
[tex]\log_363=\log_3(9\times 7)[/tex]
[tex]\log_363=\log_3(3^2\times 7)[/tex]
[tex]\log_363=\log_3(3^2)+\log_3(7)[/tex] [tex][\because \log ab=\log a+\log b][/tex]
[tex]\log_363=2+ \log_3(7)[/tex] [tex][\because \log_aa^x=x][/tex]
[tex]\log_363=2+1.77[/tex] [tex][\because \log_37=1.77][/tex]
[tex]\log_363=3.77[/tex]
Therefore, the value of [tex]\log_363[/tex] is 3.77.
Applying logarithm properties, it is found that:
[tex]\log_3{63} = 3.77[/tex]
We want to find [tex]\log_3{63}[/tex], considering that [tex]63 = 7 \times 9 = 7 \times 3^2[/tex], we have that:
[tex]\log_3{63} = \log_3{(7 \times 3^2)}[/tex]
The first property applied is:
[tex]\log{a \times b} = \log{a} + \log{b}[/tex]
Hence:
[tex]\log_3{63} = \log_3{(7 \times 3^2)} = \log_3{7} + \log_3{3^2}[/tex]
The next property is:
[tex]\log_a{a^b} = b[/tex]
Hence:
[tex]\log_3{7} + \log_3{3^2} = 1.77 + 2 = 3.77[/tex]

Simplify. 8(2x - 3) + 11x
Answer:
27x-24
Step-by-step explanation:
Using distributive property, we can simplify 8(2x-3) to 16x-24. That becomes 16x-24+11x.
Then, we can add 16x and 11x to get 27x.
The answer will be 27x-24.

Shayla bought 24 cupcakes. Each cupcake cost $0.35, including tax. Of the cupcakes she bought, 2 3 2 3 were vanilla, 1 12 1 12 were chocolate, and the rest were strawberry. What was the total cost of only the vanilla cupcakes?
Answer:
[tex]Vanillas = \$5.6[/tex]
Step-by-step explanation:
Given
[tex]Cup\ Cakes = 24[/tex]
[tex]Cost = \$0.35[/tex] (each)
[tex]Vanilla = \frac{2}{3}[/tex]
[tex]Chocolate = \frac{1}{2}[/tex]
Required
Determine the cost of all vanilla cupcakes
First, we need to determine the number of vanilla cakes.
This is calculated by multiplying the fraction of Vanilla by number of cupcakes
So:
[tex]Vanilla = \frac{2}{3} * 24[/tex]
[tex]Vanilla = \frac{2 * 24}{3}[/tex]
[tex]Vanilla = \frac{48}{3}[/tex]
[tex]Vanilla = 16[/tex]
Since 1 cupcake costs $0.35.
16 would cost 16 * $0.35
So:
Vanillas: ;;;;; [tex]16 * \$0.35 = \$5.6[/tex]

Lee sold 16 hats.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Cost of 1 hat= $8
Cost of shirt = $12
Total cost of spirit wear= $272
let the number of hats sold be x
and, let the number of shirts sold be y
So, 8x+ 12y= 272
and, x+ y= 28
Solving the above equations we get
8(28- y) + 12y= 272
224 - 8y + 12y = 272
4y = 48
y = 12
and x= 28- 12 = 16
Hence, Lee sold 16 hats.

Complete question :
Misaki cut some wood for a bookcase she is building.She needs to find how many 1/3 ft boards she can make from a 5 ft board.Explain how to model with fraction bars to solve the problem
Answer:
15
Step-by-step explanation:
Total Size of board = 5 feets
Size of board to be made = 1/3 feets
Number of 1/3 feets board to be made from 5 feets board :
Total size of board / size of board to be made
5 feets ÷ 1/3 feets
5 feets * 3 / 1 feets
= 15
Hence, number of 1/3 feets board that can be made from 5 feets board = 15

What rule would you allow to test weather (x,y) is on line l
Answer:
Step-by-step explanation:
If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.
Slope of a line passing through two points C(4, 5) and D(8, 10),
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{10-5}{8-4}[/tex]
m = [tex]\frac{5}{4}[/tex]
Equation of the line passing through C(4, 5) and slope m = [tex]\frac{5}{4}[/tex]
y - y' = m(x - x')
y - 5 = [tex]\frac{5}{4}(x-4)[/tex]
y = [tex]\frac{5}{4}x-5+5[/tex]
y = [tex]\frac{5}{4}x[/tex]
If point B(4, 0) lies on the line CD,
0 = [tex]\frac{5}{4}(4)[/tex]
0 = 5
Which is not true.
Therefore, point B doesn't lie on line CD.

In the equation, we are told that d(t) = 300,000t, where t is the time in seconds and d(t) is the distance in kilometers.
1. In this part of the question, it asks for the distance after 15 seconds. To solve we plug 15 in for t.
d(t) = 300,000(15)
d(t) = 4500000 kilometers
2. In this part of the question, it is asking for time after going 12,000,000 kilometers (twelve million). To solve, we solve for t by dividing 300,000.
12,000,000 = 300,000(t)
40 = t

Answer:
The value of n for this data is 6
Step-by-step explanation:
The given data is:
3, 12, 15, 25, 30, 40
In a set of given data, n is used to represent the number of values in a dataset. The values are also called observations. Hence, the total number of observations in a dataset are denoted by n.
In the given dataset, total values are 6.
So,
n = 6
Hence,
The value of n for this data is 6

Rectangles P, Q, R, and S are scaled copies of one another. For each pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1. Four rectangles, labeled P, Q, R and S. Each rectangle is a scaled copy of one another. Ranked in order from least to greatest, the area of the rectangles are as follows: the area of P is equal to S, which are less than the area of Q, which is less than the area of R. From P to Q from P to R from Q to S from Q to R from S to P from R to P from P to S
I attached a diagram that will aid the understanding of the question.
Firstly, I would love to review what a scale factor is before going into the question.
If you have two shapes that are similar, that is they have corresponding angles, then the scale factor of one to the other is simply the ratio of any two corresponding lengths in the two similar geometric figures.
Looking at these figures in the question, we see that R is an enlargement of the other rectangles while Q is an enlargement of P and S. With this information we can answer the questions:
1. From P to Q, the scale factor greater than one because Q is bigger than P.
2. From P to R, the scale factor is greater than one for the same reason.
3. From Q to S, the scale factor is less than one because S is smaller than Q.
4. From Q to R, the scale factor is greater than one because R is bigger than Q.
5. From S to P, the scale factor is equal to one because they are equal.
6. From R to P, the scale factor is less than one because p is smaller than R.
7. From P to S, the scale factor is equal to one because they are equal.

Find the limit !!!!!!
Answer:
1/8.
Step-by-step explanation:
Use l'Hopitals rule - we find the derivative of top and bottom of the fraction.
Derivative of the numerator = 0 - 1/2 (16 - x)^-1/2 -1
= 1 / [ 2 * (16 - x)^1/2
Derivative of the denominator = 1
When x approaches 0 this is 1 / (2*4)
= 1/8.
Another way to do this is to multiply top and bottom by 4 + (16 - x)^1/2
This becomes 16 - (16 - x) / x(4 + (16-x)^1/2)
= 1 / (4 + (16 + x)^1/2
When x ---> 0
this = 1 /(4 + 4)
= 1/8.
