Which statement explains whether Juli is correct?
a. She is correct because she can multiply 6 and 10 by any number to form an equivalent ratio.
b. She is correct because 6:10 can be written as 1:2 and there are an infinite number of ratios for 1:2.
c. She is not correct because the multiplication table does not include multiples of 10.

Scientists sometimes use analogies, or comparisons to other ideas and objects, to explain the nature of science. Are scientific ideas MORE like a piece of glass or a piece of aluminum foil?
Answers
Answer:
Step-by-step explanation:
How about both?
Glass permits you to see what is going on inside a closed container. Usually it is microscopic view of something that is very tiny to start with.
It's like foil in that what you are looking at can change dramatically very quickly. If you take an ink drop and put it water, the random motion of the water molecules diffuses the ink (spreads it out). This is called diffusion or Brownian movement.
It is like the foil because the crumpled foil has no set pattern.
Answer:
I would see it as a piece of glass since these ideas can be proven otherwise at any time.
Step-by-step explanation:
Throughout history, analogies have played an important role in scientific discoveries, not as proof, but as inspiration. Analogies have also played an important role in explaining those discoveries (Kaiser, 1989).

PLS I NEED HELP ON THIS QUESTION
Answers
Answer:
Step-by-step explanation:
First, you should find the angle x because it will help in solving the angle y. A straight line adds up to 180 degrees, therefore x+y = 180
For the triangle on the left, sum up the angles and set it to 180 degrees.
60 + 38 + x = 180
x = 82 degrees
Now solve for y by doing this
82 + y = 180
y = 98 degrees
While I'm here, Ill solve for z because it will most likely ask in the next question.
26 + 98 + z = 180
z = 56 degrees

This is (compound) probability: Picking two numbers from 1-10 and getting a multiple of 3 both times.
Answers
Answer:
There are 10 counters in the bag and you want the 4
As their is only one for the probability is
1/10
There are now 9 counters left in the bag.
You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)
There are only four even counters in the bag of nine counters so the probability is
4/9
As you want both of these to occur, you need to multiply them
1/10 x 4/9 = 49/90
Step-by-step explanation:
The probability of getting a multiple of 3 both times is 2/30.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
We are randomly picking two numbers from 1-10.
Multiple of 3 between 1 and 10 are 3, 6, 9.
To find the probability:
Here, we are considering the that the numbers are chosen without replacement.
The probability of getting a multiple of 3 both times,
= 3/10 x 2/9
= 6/90
= 2/30
Therefore, the probability is 2/30.

Jack is making lemonade and mixes 3 liters of sugar with 8 liters of lemon juice. Which ratio of liters of sugar to lemon juice will make the concentration of lemonade?
A: 15 to 32
B: 9 to 6
C: 12 to 32
D: 6 to 24
Answers
Answer:
C. 12 to 32
Step-by-step explanation:
The simplified ratio would be 3:8
So multiply 3*4=12
And multiply 8*4=32
12:32
The reason the other ones wouldn't work is because 3 and 8 are not multiplied by the same number
For example
A.)15 to 32 wouldn't work because there not multiplied by the same number
3*5=15
8*4=32

The measures of the angles of △ABC are given by the expressions in the table.
Angle Measure
A (6x−1)°
B 20°
C (x + 14)°
What are the measures of angles A and C?
Answers
Answer:
First You add all given angles up to equal 180 to give you x then you plug x into equations
Step-by-step explanation:
A= 125 degrees
C= 35 degrees
Answer:
Angle A = 125°
Angle C = 35°
Step-by-step explanation:
This is the equation you would have to solve:
Angle A + Angle B + Angle C = 180°
Fill in the values given:
(6x-1)° + 20° + (x+14)° = 180°
The parentheses don't really matter here. Go on to combine like terms. This gives you:
7x + 33 = 180°
Solve for x. Subtract 33 on both sides. This gives 7x = 147. Divide both sides by 7. This gives x = 21.
Now, go back and fill in 21 for x in the expressions for angles A & C.
Angle A:
6(21) - 1 = 125°
Angle C:
21 + 14 = 35°
You can check your answers using the first equation I mentioned:
Angle A + Angle B + Angle C = 180°
125° + 20° + 35° = 180°
This is a true equation. Therefore, the final answers are:
Angle A = 125°
Angle B = 20°
Angle C = 35°

The quotient of a number decreased by 7 and -2 is -10.
Answers
Step-by-step explanation:
First, a quotient is the answer to a division equation.
So its like y÷z=x
X is our quotient.
Since x is -10 when decreased by 7 and -2, we can write:
x-7-(-2)=-10
x-7+2=10
x-5=10
x=15
We now know that x is 15.
Using that, we can write out our equation.
Since you say do not solve, i have purposefully NOT solved this.
You should use y as a dividend and z as a divisor!
Good luck.
