Answer:
[tex]P(Red) = \frac{3}{20}[/tex]
Step-by-step explanation:
Given
[tex]Red = 3[/tex]
[tex]Trials = 20[/tex]
Required
Determine the experimental probability of next marble being red
This is calculated as:
[tex]P(Red) = \frac{n(Red)}{Trials}[/tex]
Substitute values for n(Red) and Trials
[tex]P(Red) = \frac{3}{20}[/tex]

What is 2074 as a percent?
Answer:
207400%
Step-by-step explanation:
Look at the decimal number 2074 as 2074 out of one. Furthermore, percent means per hundred. So the task is to convert 2074 out of one to 2074 out of one hundred.
The equation to solve the problem is displayed below where x is the 2074 as a percentage.
2074
/1
=
x
/100
Please mark brainliest if correct and have a blessed day!
We solve the equation for x above by first multiplying each side by one and then multiplying each side by one hundred. Thus, the answer to 2074 as a percentage is:
207400%
Answer:
the answer is 207400% I do believe
There are two routes Lucas can take to walk to school. Route A is 2 and StartFraction 1 over 8 EndFraction miles and is StartFraction 3 over 8 EndFraction mile longer than route B. The equation b + StartFraction 3 over 8 EndFraction = 2 and StartFraction 1 over 8 EndFraction can be used to represent this situation, where b is the length of route B. How many miles will Lucas walk if he takes route B?
1 and one-half miles
1 and three-fourths miles
2 and one-fourthmiles
2 and one-half miles
Answer:
I know im late, but it would be B!
Answer:
If Lucas walks through route B, the length of route B is 1 and 3/4 miles. Then the correct option is B.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
There are two routes Lucas can take to walk to school.
Route A is 2 and 1/8 miles, and Route A is 3/8 mile longer than route B. The equation b + 3/8 = 2 + 1/8 can be used to represent this situation, where b is the length of route B.

Then, add those two area: 36 + 9 = 45 square inches
Mary ordered dinner for 10 people.Three people ordered the 4.75 chicken dinner, two people ordered the 4.95 fish dinner and five had beef dinner at cost of 6.75 each. What was the average cost of each dinner at Mary's party
Answer: 5.79
Step-by-step explanation:
From the question,
3 people ordered the 4.75 chicken dinner. The cost will be:
= 4.75 × 3
= 14.25
2 people ordered the 4.95 fish dinner. The cost will be:
= 4.95 × 2
= 9.9
5 had beef dinner at cost of 6.75 each. This cost will be:
= 6.75 × 5
= 33.75
Total cost will be:
= 14.25 + 9.9 + 33.75
= 57.9
Therefore, the average cost of each dinner at Mary's party will be:
= Total cost / Number or people
= 57.9 / 10
= 5.79

10x-8x=9+19
2x=28
X=28/2
X=14
14 is the answerr
Answer:
14
Step-by-step explanation:
because u bring the 8x to 10x which would be 2x. and the u bring the 19 to nine, and it would be 28. u take away the 2 and bring it to the 28, and divide it by 2. u would get 14
How much is 78 cents per pound for 5 pounds

A car dealership increased the price of a certain car by 13%. The original price was $47400 what is the new price?
Answer:
Step-by-step explanation:
To get the new price of the car multiply the original price by the percent increase in decimal form +1. 11% in decimal form is 0.11 = 11/100. Add one to this and you get 1.11 = 1 + 0.11. So now multiply $49,800 * 1.11 = $55,278. If the problem had said they decreased the price by 11% you would use 1 - 0.11 = 0.89 because 89% is 11% less than 100%.

how do I simify by combining like terms
Answer: Like terms are combined together in algebraic expression so that the result of the expression can be calculated with ease. For example, 7xy + 6y + 6xy is an algebraic equation who's like terms are 7xy and 6xy. Therefore, this expression can be simplified by combining like terms as 7xy + 6xy + 6y = 13xy + y.
Step-by-step explanation:
Answer:
If in a equation there are numbers that have the same letters you can just add them or subtract them depending on the signs.
Step-by-step explanation:
For example this equation:
2x + 7b - 7x + 9b + 1a - 22a
So you just put them in different categories(Remember to bring them with the sign that's in front of each number) after that you just add or subtract them
category x(only numbers that have x's go here): +2x-7x = -5x
category b (only numbers that have b's go here): +7b+9b = +16b
category a (only numbers that have a go here): +1s-22b = -21a
now just put them in the same equation:
-5x+16-21a
and done!^^
Hope this example helped~

Subtract 2x^2+ 6x - 5 from 7x^2+ 3x + 4.
Answer:
− 5[tex]x^{2}[/tex] + 13x −6
By subtracting "[tex]2x^2+ 6x - 5[/tex]" from "[tex]7x^2+ 3x + 4[/tex]" we get "[tex]5x^2-3x+9[/tex]". A further solution is below.
Given equations are:
→ [tex]2x^2+6x-5[/tex]...(equation 1)
→ [tex]7x^2+3x+4[/tex]...(equation 2)
By subtracting "equation 1" from "equation 2", we get
→ [tex](7x^2+ 3x + 4)-( 2x^2+ 6x - 5)[/tex]
→ [tex]7x^2+3x+4-2x^2-6x+5[/tex]
→ [tex]5x^2-3x+9[/tex]
Thus the above solution is the appropriate one.

What is the greatest common factor of the terms of the polynomial below? 8x^4 - 12x^3 + 20x^2
Answer: I think the greatest common factor is 4x^2
Step-by-step explanation:
Find the numerical common factors. Which are 8, -12, and 20. Find the variable common factors for x^4, x^3, and x^2. Multiply them together. Then break down the factors on both sides and pick the biggest one. Finally multiply them together. (I’m sorry, I’m very bad at explaining things.)

Step-by-step explanation:
Distribute 3 to all the numbers on the other parenthesis and the answer would be: 3x^2-6x-3
Now distribute x to that same parenthesis which would be like distributing one so it will be kept the same: x^2-2x-1
Now combine like terms:
