en una encuesta a 200niños sobre el programa de T.V. que más les gusta ver ,se encontró que a 30 niños ven dibujos animados 45 niños miran películas animadas solamente 55niños miran programas sobre animales 38 niños miran programas sobre animales y dibujos animados 32 niños miran los tres tipos de programas encuentra el porcentaje de cada grupo
Answer:
15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.
Step-by-step explanation:
Dado que en una encuesta a 200 niños sobre el programa de TV que más les gusta ver se encontró que 30 niños ven dibujos animados, 45 niños miran películas animadas, 55 niños miran programas sobre animales, 38 niños miran programas sobre animales y dibujos animados y 32 niños miran los tres tipos de programas, para determinar el porcentaje de cada grupo se deben realizar los siguientes cálculos:
30/200 = 15/100 = 15%
45/200 = 22.5/100 = 22.5%
55/200 = 27.5/100 = 27.5%
38/200 = 19/100 = 19%
32/200 = 16/100 = 16%
Así, 15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.
Mei has 2 yellow teacups and 5 brown teacups Which ratio compares the number of brown teacups to the total number of teacups
Answer: 5: 7
Step-by-step explanation:
The total number for teacups: 2 yellow teacups + 5 brown teacups = 7 teacups
the ratio compares the number of brown teacups to the total number of teacups is :
5: 7
The ratio that compares the number of brown teacups to the total number of teacups is 5: 7
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We are given that Mei has 2 yellow teacups and 5 brown teacups.
The total number for teacups is;
2 yellow teacups + 5 brown teacups = 7 teacups
Therefore, the ratio compares the number of brown teacups to the total number of teacups can be;
5: 7

You are planning a trip of 900 miles. Your car gets about 21 mpg. Gasoline costs $1.59 per gallon. How much should you budget for gas on this trip? Round answer to the nearest ten (10)
Answer:
$64.3
Step-by-step explanation:
Given the following
Total distance = 900miles
Rate per gallon = 21miles per gallon
rate = distance/time
Get the number of gallons used;
Number of gallons used = 900/21
Number of gallons = 42.857gallons
If coost of 1 gallon is $1.50
42.857gallons will cost 42.857 * 1.50
42.857gallons will cost $64.3
Hence he should budget $64.3 for the trip

Step-by-step explanation:
If you need the probability of both answers, convert 4/10 ( or 0.4 ) to 40/100 and 0.25 stays 25/100 and if you add 25 + 40 you get 65 so 0.65 or 65/100 is the probability both boys will score!
Hope this Helps! :D
Which figures appear to be congruent?
An image of 5 triangles on a 14 by 12 grid is shown.Triangle 1 has a base that is 4 units long. The upper vertex is 4 units above the midpoint of the base. To the right, triangle 2 has a horizontal leg that is 3.5 units long and a vertical leg that is 4 units long. A small square is positioned in the triangle at the lower left vertex. Below triangle 1, triangle 3 has a horizontal leg that is 3.5 units long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the upper right vertex. Triangle 4 is toward the center of the grid. It has a horizontal leg that is 1 unit long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the upper right vertex. Triangle 5 is to the lower right. It has a horizontal leg that is 6 units long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the lower left vertex.

I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am positive and prime. What number am i?
Answer:
2, 3, 5, 7, 11, 17, 19, 23
Step-by-step explanation:
The segment between - 15 and 25 has 40 numbers given by
25 - -15
= 25 + 15
= 40
Divided into 4 segments, each would contain 10 numbers such that the
1st segment is from -15 to -5 (which is -15 + 10)
2nd segment is from -5 to 5 (which is -5 + 10)
3rd segment is from 5 to 15 (which is 5 + 10)
4th segment is from 15 to 25 (which is 15 + 10)
Given that the unknown number is prime and positive this may be
2 or 3 or 5 from the 2nd segment
7 or 11 from the third segment
17 or 19 or 23 from the 4th segment

tell me if the statement below is sometimes, always, or never true. justify your reasoning, (the Expressions x - 3 + y -3 represent the same value.)
Answer:
Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true
Step-by-step explanation:
We are given two expressions: x -3 and y - 3
Here x and y are two different variables.
These expressions are equal, when the value of x and the value of y are equal.
x - 3 = y -3 if x = y.
Therefore, the two expressions have the same value in sometimes.
That is, when x = y, then the value of two expressions are the same.
Example.
If x = 2 and y = 2, then
x - 3 = y - 3
2 - 3 = 2 - 3
-1 = -1
If they have different values, for x = 2 and y = 3
x - 3 = y - 3
2 - 3 = 3 -3
-1 = 0
Which is not true.
Therefore, the answer is sometimes.

Find the simple interest and amount when principal = Rs. 6000, rate = 6% per annum and time = 4 years
Given:
Principal = Rs. 6000
Rate of simple interest = 6% per annum.
Time = 4 years
To find:
The simple interest and amount.
Solution:
Formula for simple interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest and t is the number of years.
Putting P=6000, r=6 and t=4, we get
[tex]I=\dfrac{6000\times 6\times 4}{100}[/tex]
[tex]I=60\times 6\times 4[/tex]
[tex]I=1440[/tex]
Now,
[tex]Amount=Principal+Interest[/tex]
[tex]Amount=6000+1440[/tex]
[tex]Amount=7440[/tex]
Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.
