1 answer:
-BARSIC- [3]3 years ago
7 0

Answer: 3.3

Step-by-step explanation:

200(x-0.3)=600

Multiply x by 200 and 0.3 by 200

200x-60=600

Add 60 to both sides

200x-60=600

        +60  +60

Add them

200x=660

Divide

660/200 = 3.3

Answer: 3.3

Saleem has $20. A fish tank that he wants to buy costs $140. He earns $23 per day at a restaurant. Saleem wants to know how many
mr_godi [17]

Answer:

Since he can't work a fraction of a day, he'll have to work at least 6 days to have enough money for the tank. The inequality hat represents his situation is 23*x + 20 >=140.

Step-by-step explanation:

In order to create an inequality to this problem we first need to take the initial amount he has and sum it with the days he has to work "x" multiplied by the amount he earns each day. We then have:

saleem money = 20 + 23*x

Since he wants to buy a $140 fish tank he needs to work until his money is greater or equal than this amount. So we have:

23*x + 20 >= 140

23*x >= 140 -20

23*x >= 120

x >= 120/23

x >= 5.22

Since he can't work a fraction of a day, he'll have to work at least 6 days to have enough money for the tank. The inequality hat represents his situation is 23*x + 20 >=140.

A triangle's measures are in the extended ratio of 2:4:9 find the measures of angles
Margaret [11]

Answer:

24°:48°:108°

Step-by-step explanation:

Since the sum of angles in a triangle is 180°, we can do 180÷15 to find the degree for 1 in the ratio. 180÷15 = 12.

12°×2 = 24°

12°×4 = 48°

12°×9 = 108°

The ratio is 24°:48°:108°

The correct statement compares the means of the data in the dot plots is option C; the mode is greater for Mrs. Ramos’s class.

<h3>What are the median and mode of the data?</h3>

Median represents the middle value of the given data when arranged in a particular order.

Mode is that number that appears most frequently in the given set of data.

Given;

The Number of pets in Mr. McIntyre’s class ;

0,0,0,0,0,1, 1, 1, 1, 1, 4, 4, 4, 4, 1,

Median = 1

Mode = 0 and 1

The Number of pets in Mrs. Ramos’s Class;

0, 1, 1, 2, 2, 3, 3, 3, 3, 4, 4, 4, 3, 3, 3

Median = 3

Mode = 4 and 5

Hence, C; The mode is greater for Mrs. Ramos’s class.

The remaining part of the question is

"Which statement correctly compares the measures of center of the data in the dot plots?

The median is greater for Mr. McIntyre’s class.

The median is the same for both classes.

The mode is greater for Mrs. Ramos’s class.

The mode is the same for both classes."
