how do I solve the ratio of somthin​

Answers

Answer 1
Add the ratio terms to get the whole. Use this as the denominator. 1 : 2 => 1 + 2 = 3.
Convert the ratio into fractions. Each ratio term becomes a numerator in a fraction. 1 : 2 => 1/3, 2/3.
Therefore, in the part-to-part ratio 1 : 2, 1 is 1/3 of the whole and 2 is 2/3 of the whole.

Step-by-step explanation:

Answer:

6,300,000,000,000,000

Step-by-step explanation:

First, you want to find out much the answer will be for the powers. That means doing 10 to the 8th power and 10 to the 6th power. Once you get that, put it aside. Next, you want to go ahead and multiply 7 and 9. After you do that all you will have left is 100000000 x 1000000 x 63. Last, all you have to do is multiply 100000000 by 1000000 and that's easy because all you have to do is add the 0's and end up getting 100000000000000. Now, all you do is multiply that by 63 and you get 6,300,000,000,000,000. Hope this was helpful.

Question Help Use the GCF and the Distributive Property to find the sum. 42 + 66 Write each number as a product using the GCF as a factor, and apply the Distributive Property. 42 + 66 = (Use the operation symbols in the math palette as needed. Do not simplify.)​

Answers

Answer:

40 plus (2)42 plus 6x11

Step-by-step explanation:

Multiply

Using GCF and Distributive property on the sum of 42 and 66 gives us;

((6 * 7) + (6 * 11) = 6(7 + 11)

      GCF simply means the greatest common factor. Now, to find the GCF of 42 and 66, let us state their factors;

Factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42

Factors of 66 = 1, 2, 3, 6, 11, 22, 33, 66

       The highest factor common to 42 and 66 is 6. Thus, we can say that the GCF of 42 and 66 is 6.

We want to add 42 to 66.

42 + 66

The distributive property states that;

a(b + c) = ab + ac

Thus;

Since GCF of 42 and 66 is 6, then we have;

42 + 66 = ((6 * 7) + (6 * 11)

Using distributive property;

((6 * 7) + (6 * 11) = 6(7 + 11)

4 movie tickets cost $48. At this rate, what is the cost of:
a. 5 movie tickets?
b. 11 movie tickets?

Answers

5 movie tickets cost $60
11 movie tickets cost $132


For a you would divide 48 by 4 to see how much each ticket is which is 12, and then you would multiply 12 by 5 which is 60

For B you would do the same thing except multiply 12 by 11 which is 132

Answer:

a=60 b=132

Step-by-step explanation:

48/4=12

a=12*5

b=12*11

Whats a good explanation for a bag contains 120 marbles. Some are red and the rest are black. There are 19 red marbles for every black marble. How many red marbles are in the bag?

Answers

Answer: 114 marbles

Step-by-step explanation:

From the question, we are told that a bag contains red and black marbles which are 120 marbles in total. We are further told that there are 19 red marbles for every black marble.

Let the number of black marbles be represented by a.

The red marbles will be: = 19 × a = 19a

Based on the information given in the question,

Black marbles + Red marbles = 120

a + 19a = 120

20a = 120

a = 120/20

a = 6

Black marbles = 6

Red marbles = 19a = 19 × 6 = 114 marbles

Customers at the gym pay a membership fee to join and then a fee for each class they attend. Here is a graph that represents the situation.
•what does the slope of the line shown by the points mean in this situation?____
•what does the vertical intercept mean in this situation?_____

Answers

Answer:

Step-by-step explanation:

Customers at the gym pay a membership fee and fee for each class they attend.

From the graph attached,

- Slope of the line shown by the points means, fee per class paid by the customers.

- Vertical intercept means the membership fee to join the gym.

The slope means that each class cost $20, while the vertical intercept mean that the membership fee is $60.

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the total fee paid for undergoing x classes.

The graph passes through the point (0, 60) and (6, 180). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-60=\frac{180-60}{6-0}(x-0)\\\\y=20x+60[/tex]

The slope means that each class cost $20, while the vertical intercept mean that the membership fee is $60.
