There are 6 red marbles, 9 blue marbles, and 10 green marbles in a bag.
Several trials are performed with the results shown in the table. What is the experimental probability of randomly drawing a red marble?
Red Blue Green
16 30 34
32%
25%
20%
16%
I need help!
Answer:
I would guess 20%
Step-by-step explanation:
16+30+34)/4)x5 (this is how I think u would get it to be 100)
16/4)x5 = 20
20/100 = 20%
Im less certian about this one than the other but if u think its correct u can try it

15. The floor plan of the basement of a shopping centre is drawn to a scale of 1:400.
If a supermarket has an area of 0.25 m² on the plan, find its actual area in hectares. (1 hectare = 10 000 m²)
Answer:
4 hectaresStep-by-step explanation:
The scale factor is:
k = 1/400Applied to the area we consider k² as the area is the product of two dimensions.
Find the actual area:
0.25 m² : (1/400)² = 0.25 m² * 160000 = 40000 m² = 40000 * 1/10000 hectares = 4 hectaresHow can you use 5, 5, 5, 5, to make 24 using addition, multiplication, subtraction, or division, but without using other numbers.
Step-by-step explanation:
5×5×5=125
125-5=120
120÷5=24
Step-by-step explanation:
Find: 11/3 ÷ 2/3
The quotient is 5 and ?
Answer:
11/3 ÷ 2/3 = 5 1/2
Step-by-step explanation:
When doing divison of fractions, you do these steps
11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.
11/3 × 3/2. Now all you have to do is multiply
11/3 × 3/2 = 33/6, simplify that down is 5 3/6, which is 5 1/2
Answer 1/2
Step-by-step explanation:
i think hope this helps you friend!
Please help! Greatly appreciated. Thank you!
Answer: Q(7,-2), S(-3,6)
Step-by-step explanation:
The model shows the expression 30 +12. Which expression is equivalent to thi sum?
Answer:
There are many answers to this question like:
7x6
21x2
84/2
27+15
Step-by-step explanation:
If 30+12=42, all you really have to do is check each answer to see if it either adds up to 42, multiplies to get 42, divides to get 42, or subtracts to get 42.
Answer:
6(5+2)
3(10+4)
Step-by-step explanation:
These are just a couple of equivalent sums, I am assuming this is a sort of short response and not a multiple choose so i believe you can use this.
I WILL MARK BRAINLIEST! Solve for X
Answer:
Step-by-step explanation:
You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional. So set up two ratios that are = to each other
On the left
long side small triange / long side large triangle = base small triangle / base large triangle
On the right
hypotenuse/longest leg = hypotenuse / longest leg.
Problem A
Set up the similar Proportion
5/40 = x/20 Cross Multiply
40x = 20*5
40x = 100 Divide by 40
x = 100/40
x = 2.5
Problem B
Again set up the similar triangle proportion
15/10 = x/2 Multiply by 2
15*2/10 = x
3 = x

Jinny is selling bracelets for $2.50. So far, she has earned $175.00. She needs to earn more than $230.00 in order to meet her goal.
How many more bracelets, x, does she need to sell in order to reach her goal? Select the inequality that includes the fewest number of bracelets that she can sell and still reach her goal.
Answer: 25
Step-by-step explanation:
she’s earned 175 so far she needs 230. So 230-175=55, so she needs 55 more dollars. 55÷2. 50(price of each bracelet) = 25

3 fewer than a number squared and four
Answer:
([tex]n^{2}[/tex]+4)-3
Step-by-step explanation:
since it says "and four" i think it means it is in parenthesis
Answer:
n^2 + 1
Step-by-step explanation:
Let the unknown number be n. Then "a number squared and four" is
n^2 + 4, and 3 fewer than this result is
n^2 + 3 - 3, or n^2 + 1

Circle question of the rug
That you needed answer for is ;
3/4 pi^2
Step-by-step explanation:
Proof 1/4 pi r^2
We can state the radius of small rug is 3ft
to show Area pi 3^2 = pi 9
If the large rug is 3x this size
then pi 9^2 = pi81
So the ratio here is 1 : 9 when 3 cm or 1 : 3 radius
Ratio is 1 : 9 when 1cm or 1 : 3 radius
When 1 : 9 cm when 5cm or 1 : 3 radius
So if we are considering an expression of the larger rug
that shows 3: 1 more radius to that of the small.
1/4 pi^2 becomes 3/4 pi^2 of the smaller rug
As this is 3 x 1/4 pi^2 we show 3/4pi r^2

Answer:
2x^11
Step-by-step explanation:
distributing x^8(2x^3) makes 2 * x^3 * x^8. To multiply exponents, just add the powers together to make 11. This makes 2x^11.
Answer:
[tex]8x^1^1[/tex]
Step-by-step explanation:
Hi there!
[tex]x^8*(2x)^3[/tex]
Distribute the exponent into the parentheses:
[tex]= x^8*2^3x^3\\= x^8*8x^3\\= 8*x^3*x^8[/tex]
When two powers have the same base, add the exponents:
[tex]= 8*x^3^+^8\\= 8*x^1^1\\= 8x^1^1[/tex]
I hope this helps!
A number has many factors including 3 and 8. What other number must also be a factor of the same number?
Two "factors" are multiplies together to product another number (the product). So, for example, the prime factors of 10 are 2 and 5. Prime factors that, themselves, have only factors of 1 and themselves. Non-prime numbers, like 10, have prime factors. Note that 1 is a factor of all integers.
If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."
Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).
Practice:
What is the square root of 49?
What is the square root of 100?
What is the square root of 625?
Memorize the squares of the numbers from 1 to 10, or 1 to 20 -- that will be very helpful in math classes.
