Answer:
1:5, 5, 15
Step-by-step explanation:
The original ratio of red marbles to white marbles is 6:30 and you need to know how many white marbles are expected with 3 red marbles so you have to make the # of red marbles 3 so you can divide by 2 and you'll get 15 white marble or you could've divided both sides by 6 and get the ratio of red marbles to white marbles as 1:5 and you can see that for every one red marble there is 5 white marbles.

Solve the following system of equations using any method you want.
y + 2x = 2
2x - 5y = 14 please help
Answer:
y = - 2, x = 2
Step-by-step explanation:
Remove x and solve for y
2x - 2x - 5y - y = 12
-6y = 12
y = - 2
Substitute y back into the equation
-2 + 2x = 2
2x = 4
x = 2

George still has 40 percent of his book to read. If George has read 180 pages, how many pages does he still have to read? How do you know?
Answer: 72
Step-by-step explanation: so you do a line = line method the lines should look like they are fractions.
you do it for the both numbers the percent is always out of 100.
it should look like this
40% ?
--------- = -----------
100% 180
then you cross multiply 40 and 180 and than divide it by 100. your answer should be 72. you later replace the ? with 72
you know this because It is smaller than 180 and its bigger than the number 40.
The number pages left to read is 12 pages.
Given that, George still has 40 percent of his book to read.
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 "%".
Let the total number of pages be x.
Now, x-40% of x=180
⇒ x-0.4x=180
⇒ 0.6x=180
⇒ x=180/0.6
⇒ x=300
So, remaining pages = 300-180=120
Therefore, the number pages left to read is 12 pages.

A circle has a radius of 5/3 units and is centered at (9.2 -7.4)
Write the equation of the Circle.
Answer:
(x - 9.2)^2 + (y + 7.4)^2 = (5/3)^2
Step-by-step explanation:
We start with (x - h)^2 + (y - k)^2 = r^2. The center is (h, k) and the radius is r.
Then we have:
(x - 9.2)^2 + (y + 7.4)^2 = (5/3)^2

of the following numbers, which has the most factors of 3?
a) 81
b) 270
c) 999
d) 3333
Answer:
81 has the most factors of 3
Step-by-step explanation:
To conclude which of the following options has the most factors of 3, take each of the number's prime factorization, which will help us solve the problem.
( 1 ) 81 is a composite number and is 9 squared. Knowing that 3 squared = 9, we can say that the prime factorization of 81 = 3 [tex]*[/tex] 3 [tex]*[/tex] 3 [tex]*[/tex] 3, which can also be denoted as 3⁴.
( 2 ) 270 is a composite number. The exponents in the prime factorization are 1, 3, and 1, and therefore it's prime factorization is - 3 [tex]*[/tex] 5 [tex]*[/tex] 3 [tex]*[/tex] 2 [tex]*[/tex] 3, composed of 3 3s.
( 3 ) If we put all of it together we have the factors 3 x 3 x 3 x 37 = 999. It can also be written in exponential form, with 3 to the power of 3 - hence having 3 factors of 3.
And finally the value 3333 has the prime factorization of 3 [tex]*[/tex] 11 [tex]*[/tex] 101, and as you can see it has 1 factor of 3. 81, having 4 factors of 3, is present with the most factors, and therefore is our solution.
Number 81 has the most number of factor 3. Option A is correct.
A number from the options to be determined that has the most number of factor 3.
factors can be defined by splitting the value into multipliable values.
Here,
Factors of 81 = 3,3,3,3 Number of factor 3 = 4
Factors of 270 =2,3,3,3,5 Number of factor 3 = 3
Factors of 999 =3,3,11 Number of factor 3 = 2
Factors of 3333 = 3,11 Number of factor 3 = 1
As per the above comparison, 81 has the most number of factor 3.
Thus, Number 81 has the most number of factors 3.

Kathy found the volume of the figure using the expression (4 * 3 * 8) + (10 * 3 * 4). Sandy found the volume of the figure using the expression (3 * 10 x 4) + (4 * 3 * 4). Use the drop-down menus to explain who is correct. 10 cm Click the arrows to choose an answer from each menu, The expression for the volume of the figure was correctly determined by Choose... because the figure was divided into two rectangular → prisms that Choose...
Answer:
The correct options are;
1) Sandy is correct
2) The figure was divided into two rectangular prisms that are calculated separately
Step-by-step explanation:
Here we have to divide the figure into two rectangular prisms so as not to calculate for a dimension twice
Therefore, the figure can be split into a horizontal prism at the top with dimensions and volume = 10 × 4 × 3 and the vertical prism below will now have a dimension and hence, volume of 4 × 4 × 3
Therefore the volume of the figure is the sum of the volumes of the two prisms found as follows;
Volume of the figure = 10 × 4 × 3 + 4 × 4 × 3 = 168
We can try the othe way to confirm as follows
Volume of the prism below = 4 × 3 × 8 = 96
Volume of the horizontal prism above is now = 4 × 3 × 6 = 72
Volumre of the figure = 96 + 72 = 168
Therefore, since the volume = (10 × 4 × 3) + (4 × 4 × 3), Sandy is correct
Because the figure was divided into two rectangular prisms that are calculated separately.

Find the 26th term in the arithmetic sequence: 20, 26, 32, 38, ...
Answer:
170
Step-by-step explanation:
20 + (26 - 1)6
= 20 + (25)6
= 20 + 150
= 170
The 26th term in the arithmetic sequence: 20, 26, 32, 38, ... is 170
Given:
20, 26, 32, 38, ...
nth term of an arithmetic sequence is given bynth term = a + (n - 1) d
where,
a = first termd = common differencen = nth term20, 26, 32, 38, ...
a = 20
d = 26 - 20
= 6
26th term = a + (n - 1) d= 20 + (26 - 1) 6
= 20 + (25) 6
= 20 + 150
