Dairy bar 25 kg of fish flavored cat food and 35 kg of chicken flavored cat food for the cat rescue center he's going to divide the cat food and two packets of 300 g how many packets will he make
Answer:
200 packets
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Fish flavoured = 25kg or 25,000 gm
Chicken flavoured = 35 kg or 35,000 gm
Packets size = 300gm
So, we can calculate the number of packets by using following formula,
Number of packets = (25,000gm + 35,000gm) ÷ 300gm
Number of packets = 60,000 gm ÷ 300gm
Number of packets = 200 packets

if angle A=(5x+45) and angle A is a straight angle, find the value of x
Answer:
x = 27
Step-by-step explanation:
A = 180°
180 = (5x+45)
subtract 45 from each side:
5x = 135
divide both sides by 5:
x = 27
The value of x that makes angle A a straight angle is 27.
What are Angles?An angle is formed when two straight lines or rays meet at a common endpoint.
We need to find the value of x if angle A=(5x+45)
If angle A is a straight angle, it means that its measure is 180 degrees. Therefore, we have:
5x + 45 = 180
Subtracting 45 from both sides, we get:
5x = 135
Dividing both sides by 5, we obtain:
x = 27
Therefore, the value of x that makes angle A a straight angle is 27.

The probability that an adult who likes soccer ages 18-30 is approximately 0.444.
Given that the table is,
Age range
18-30 31-50 51+ Total
Football 15 19 17 51
Sport Baseball 7 12 18 37
Basketball 15 8 11 34
Soccer 12 9 6 27
Given:
Liked sport: Soccer
Age range: 18-30
To find the probability that an adult is aged 18-30 given that they like soccer, denoted as P(18-30 | S).
To calculate this probability, use the formula for conditional probability:
[tex]P(18-30 | S)= \frac{P((18-30) \cap (S))} {P(S)}[/tex]
P(18-30 ∩ Soccer) represents the probability that an adult is both aged 18-30 and likes soccer.
Looking at the provided table, the number of adults who like soccer and are aged 18-30 is 12.
P(Soccer) represents the probability that an adult likes soccer. The total number of adults who like soccer, regardless of age, is 27.
Now, calculate the probability:
P(18 - 30| S) = 12 / 27
≈ 0.444 (rounded to three decimal places)

Which of the following is not a measure of the center of a data set?
(1) the median
(2) the mean
(3) the range
(4) the mode
Answer:
i think its 4.
Step-by-step explanation:
The Range is not used to measure of the center of a data set.
Here,
We have to find, which is not a measure of the center of a data set.
What is Range?
The range of a set of data is the difference between the largest and smallest values.
Now,
Median is the middle number, when data is arranged in numerical order.
Mean is the average of a data set.
Mode is the data item the appears most frequently.
Hence,
Median, Mean, Mode all are used to measure of the center of a data set.
So, Only The Range is not used to measure of the center of a data set.

Step-by-step explanation:
A bag contains one green marble, two yellow marbles, four blue marbles and five red marbles. How many blue marbles would you need to add to make the probability of drawing a blue marble 1/2?
Answer:
You would have to add 4 blue marbles
Step-by-step explanation:
there are a total of 12 marbles, 4 of them being blue.
If you add 4 blue ones, there would be a total of 16 marbles and 8 of them would be blue.
8/16 = 1/2
Therefore, 4 blue marbles need to be added for the chance to draw one to be 1/2 or 50%
Answer:
Step-by-step explanation:
Since there is 1 green, 2 yellow, 4 blue, and 5 red we start with 12 marbles. For the probability of picking a blue to be 1/2 we must satisfy.
(b+x)/(12+x)=1/2. (Where x is the number of blue marbles added)
2(b+x)=12+x
2b+2x=12+x
2b+x=12
x=12-2b, since we started with 4 blue marbles
x=12-2(4)
x=12-8
x=4
So we would need to add 4 blue marbles to make the probability of picking a blue 1/2.

Answer: Yes these triangles are similar
Step-by-step explanation:
First lets write down what we know just to make life easier
x=9
TL should be similar to CH
LY should be similar to KH
The angles should be equal due to SAS
So the first thing we know is true is the fact that they have equal angles. Now we have to find out if the sides are similar or if they change by the same ratio to the other. If TL is similar to CH and TL=25 and CH=10 what is the change in size or dilation. Division should do the trick so 25/10=2.5 so TY is greater than CH by a factor of 10. Which means that LY should also be greater than KH by a factor of 2.5. If we are told that x=9 than side LY or 4(9)-1=35 and KH 9+5=14
So side KH is 14 and LY is 35. Now to check if they are similar then KH should be greater by a factor of 2.5. If this is not true than the sides are not similar. 35/2.5=14
Since 35 divided by 2.5 is 14 we can tell both sides TL and LY are greater than KH and CH by a factor of 2.5
