Answer:
4.1145
Step-by-step explanation:
You can use the following formula to solve this kind of problems,
[tex] log_{a}(b) + log_{a}(c) = log_{a}(bc) [/tex]
So, let's start of with log4_(300). Since the question have already gave log4_(3) =0.7925 and log4_(5) =1.1610. It means that you have to split the 300 into the simplest form where almost all of the numbers are 3 and 5.
[tex] log_{4}(300) = log_{4}(4 \times 5 \times 3 \times 5) \\ = log_{4}(4) + log_{4}(5) + log_{4}(3) + log_{4}(5) \\ = 1 + 1.1610 + 0.7925 + 1.1610 \\ = 4.1145[/tex]

What is the product?
Answer:
product is the result of multiplication or an expression that identifies factors to be multiplied..
The product of the given expression (7x²)(2x³ + 5)(x² - 4x - 9) is,
[tex]14x^{7} - 56 x^6 - 126 x^5 + 35x^{4} - 140x^{3} - 315 x^2[/tex]
The product between expressions can be defined as the outcome or result obtained by multiplying two or more numbers, terms, or quantities together. It represents the combined value or the total when multiple factors are multiplied.
The given expression is,
(7x²)(2x³ + 5)(x² - 4x - 9)
Multiplying the first two expressions,
[tex](7 \times 2 x^{2+3} + 7\times 5x^2)(x^2 -4x -9)\\(14 x^5 + 35 x^2)(x^2 -4x -9)\\[/tex]
Now again multiplying these two expressions
[tex]14x^{5+2} - 4 \times 14 x^5 - 14 \times 9 x^5 + 35x^{2+2} - 35 \times 4x^{2+1} - 35 \times 9 x^2[/tex]
Simplifying this we get,
[tex]14x^{7} - 56 x^6 - 126 x^5 + 35x^{4} - 140x^{3} - 315 x^2[/tex]
Hence,
The product of the given expression is,
[tex]14x^{7} - 56 x^6 - 126 x^5 + 35x^{4} - 140x^{3} - 315 x^2[/tex] .

When I started here, there were 500 employees. Since then, we have added 35% more employees, so we now have a total of ______ employees
Answer: 675
Step-by-step explanation:
Since the starting amount of employees is 500 we can say that 100%=500.
Adding 35% more employees means that we're adding 35% to the existing 100%, which means we need to find 135% of 500.
To solve we must multiply 135% by 500. 135% as a decimal is 1.35, so we multiply 1.35(500)=675.
Therefore, they now have a total of 675 employees.

Step-by-step explanation:
Perimeter of a rectangle
Perimeter = 2(width + length)
Given information:
[tex]\textsf{width} = 3\sqrt{8}[/tex]
[tex]\textsf{length} = 4\sqrt{20}+2\sqrt{24}[/tex]
Equivalent Expression 1
Substitute the given information into the formula:
[tex]\sf Perimeter = 2(3\sqrt{8}+4\sqrt{20}+2\sqrt{24})[/tex]
Equivalent Expression 2
Using the distributive property law, this can also be written as:
[tex]\sf Perimeter = 2(3\sqrt{8})+2(4\sqrt{20}+2\sqrt{24})[/tex]
Equivalent Expression 3
Distribute the parentheses and simplify the radicals:
[tex]\begin{aligned}\sf Perimeter & = \sf 2(3\sqrt{8}+4\sqrt{20}+2\sqrt{24})\\& = \sf 6\sqrt{8}+8\sqrt{20}+4\sqrt{24}\\& = \sf 6\sqrt{4 \cdot 2}+8\sqrt{4 \cdot 5}+4\sqrt{4 \cdot 6}\\& = \sf 6\sqrt{4}\sqrt{2}+8\sqrt{4}\sqrt{5}+4\sqrt{4}\sqrt{6}\\& = \sf 6 \cdot 2 \sqrt{2}+8 \cdot 2 \sqrt{5}+4 \cdot 2 \sqrt{6}\\& = \sf 12 \sqrt{2}+16 \sqrt{5}+8 \sqrt{6}\end{aligned}[/tex]
Equivalent Expression 4
Distribute the parentheses and rewrite the square roots as [tex]\sf \sqrt{a}=a^{\frac{1}{2}}[/tex] :
[tex]\begin{aligned}\sf Perimeter & = \sf 2(3\sqrt{8}+4\sqrt{20}+2\sqrt{24})\\& = \sf 6\sqrt{8}+8\sqrt{20}+4\sqrt{24}\\ & = \sf 6 \cdot 8^{\frac{1}{2}}+8 \cdot 20^{\frac{1}{2}}+4 \cdot 24^{\frac{1}{2}}\end{aligned}[/tex]
Equivalent Expression 5
Rewrite the square roots as [tex]\sf \sqrt{a}=a^{\frac{1}{2}}[/tex] :
[tex]\sf Perimeter=12 \cdot 2^{\frac{1}{2}}+16 \cdot 5^{\frac{1}{2}}+8 \cdot 6^{\frac{1}{2}}[/tex]

Write 0.2 repeating as a fraction in simplest form.
0.2 Repeating Decimal is 2/9 as a Fraction
Answer:
2.9
Step-by-step explanation:
We let 0.2 be x.
Since x is recurring in 1 decimal places, we multiply it by 10.
10x = 2.2
Next, we subtract them.
10x - x = 2.2 - 0.2
9x = 2
Lastly, we divide both sides by 9 to get x as a fraction.
Answer: x = 2.9 or 2/9.

The trolley rolled at a rate of 10 feet per second how far does it go in a minute
9514 1404 393
Answer:
600 feet
Step-by-step explanation:
There are 60 seconds in a minute, so the trolley travels 60 times as far as it does in one second.
(60 seconds/minute) × (10 feet/second) = 600 feet/minute
The trolley goes 600 feet in a minute.
Thr area of a square is 36 centimeters what is the length of each square
Answer:
6 cm
Step-by-step explanation:
The area of a square is its side squared(multiplied by itself). In order to find the length of the square, you would need to find a number which is multiplied by itself to get 36. This number is 6, meaning the length of the square is 6 cm.

Suppose you write each letter of the alphabet on a different slip of paper and put the slips into a hat. What is the probability of drawing one slip of paper from the hat at random and getting a vowel?
Answer:
5/26 chance because there is only five vowels in the alphabet
Answer:
Not counting y as a vowel: 5/26 or a 19.23% chance
Step-by-step explanation:
There are a total of 26 letters in the alphabet.
There are 5 vowels (a, e, i, o, u)
Picking a vowel has a 5 in 26 chance of occurring.
