The farmer walks by the pen with the chickens and pigs. He counts 18 heads and 50 feet. How many of each, chicken and pigs, are there?
Answer:
chickens = 11
pigs = 7
Step-by-step explanation:
this would be solved using simultaneous equation
let c = chicken .
p = pigs
A normal pig and chicken both have 1 head. thus :
c + p = 18 equation 1
A normal pig has 4 legs and a normal chicken has 2 legs. Thus
2c + 4p = 50 equation 2
multiply equation 1 by 2
2c + 2p = 36 equation 3
subtract equation 3 from 2
2p = 14
p = 7
substitute for p in equation 1
c + 7 = 18
c = 11

a bike rental company charges $12, which includes the first 30 minutes of biking. thereafter, the company charges an additional $0.25 per minute. write a numeric sequence for the first 5 minutes of the 30 minutes.
Answer:
0.4, 0.8, 1.2 ,1.6 ,2.0
Step-by-step explanation:
First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.
Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.
Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.
The numeric sequence is 0.4, 0.8, 1.2 ,1.6 ,2.0
The calculation is as follows:
Here we have to divide $12 by 30. That will equal 0.4 a minute.
Now if we add 0.4 for each minutes
So the series be like
0.4 for the first, 0.8 is 2 minute and so on.

Emi computes the mean and variance for the population data set 87, 46, 90, 78, and 89. She finds the mean is 78. Her steps for finding the variance are shown below.
What is the first error she made in computing the variance?
A.) Emi failed to find the difference of 89 - 78 correctly.
B.) Emi divided by N - 1 instead of N.
C.) Emi evaluated (46 - 78)2 as -(32)2.
D.) Emi forgot to take the square root of -135.6.
Answer: Choice C) Emi evaluated (46-78)^2 as -(32)^2
Explanation:
The "46-78" is inside the parenthesis, so the result must also stay in the parenthesis. This means (46-78)^2 would become (-32)^2. The negative must be inside the parenthesis as well. Squaring the "-32" leads to a positive result, so every item being added is positive after the squaring operations are applied.

pls help asap 15 point and brainliest
Answer:
The distance between the two points is 10.3
Step-by-step explanation:
To find the length of the line joining the two points, we are going to use the distance formula
Mathematically, we have this as;
D = √(y2-y1)^2 + (x2-x1)^2
From the question;
(x1,y1) = (-3,4)
(x2,y2) = (2,-5)
Thus, we have it that;
D = √((-5-4)^2 + ((2-(-3)^2
D = √81 + 25
D = √(106)
D = 10.3

Given f(x) = 3x2 + kx + 19, and the remainder when
f(x) is divided by x + 3 is 37, then what is the value of k?
Answer:
[tex]f{x} = x + 3 = 0 \\ x = - 3 \\ f( - 3) = 3( - 3) {}^{2} + k( - 3) + 19 = 37 \\ f( - 3) = 27 - 3k + 19 = 37 \\ f( - 3) = 46 - 3k = 37 \\ f( - 3) = 46 - 37 = 3k \\ f( - 3) = 9 = 3k \\ f( - 3) = k = 3[/tex]

Three boxes of cereal are shared equally among
8 boys. What fraction of a box does each boy get?
Answer:
3/8
Step-by-step explanation:
We want to find out how much each person gets per box, so all we have to do is divide the three boxes by three and the 8 by three to get how much each person gets. When we do that, we get 3/8. Literally, that means each boy gets 3/8 of a box of cereal.

PLS MAKE ME BRAINLIEST
answer this qustion plz and if get right i might give you brainlist
Answer:
A
Step-by-step explanation:
SO right off the bat it cannot be c, for they do definatly change.
Next, lets find out how much they change by.
The median would now be 120. Since adding 1 more number would make it just 120. Instead of it being 120+130/2.
This is a decrease of 5. Because we can just subtract normal number by new number: 125-120=5.
Now, the mean is already 500/4. This equals 125.
So lets add 0 to that. So now we must divide it by 1 more number, 4+1=5.
That is 500/5. This equals 100.
This is a decrease of 25. Because we can again subtrasct the normal number by the new number: 125-100=25
That is 5x more of a decrease than the mean.
SO it must be A, since the mean decreased more than the median.
The temperature outside changed from 79°F to 44°F over a period of five days. If the temperature changeu
amount each day, what was the daily temperature change?

OB. -7°F
ОС.
-35°F
OD. 7°F
Answer:
B: -7°F
Step-by-step explanation:
79-44=35
Because its over a period of five days we would divide
35÷5=7
Since the numbers are going down its negative

The ratio of Warrior fans to Laker fans at a basketball game was 5 to 3. If
there were 21 Laker fans, how many Warrior fans are there
Answer:
35
Step-by-step explanation:
Create a proportion where x is the number of Warrior fans
[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{21}[/tex]
Cross multiply and solve for x
105 = 3x
35 = x
So, there were 35 Warrior fans
Answer:
[tex] \bf\huge warrior \: fans = 35[/tex]
Step-by-step explanation:
Given that :The ratio of Warrior fans to Laker fans at a basketball game was 5 to 3.If there were 21 Laker fans.to find :how many Warrior fans are there.let us assume :warrior fans is X .explanation :finding the warrior fans
⟼ warrior : laker fans = 5 : 3 = x : 21
⟼ 5 : 3 = x : 21
⟼ [tex]\frac{5}{3} \times \frac{x}{21} [/tex]
⟼ x = 5 × 7
⟼ x = 35.
⟼ warriors fans = 35.
∴ laker fans is 21 and warriors fan is 35.
∴ warriors : laker fans = 5 : 3 = 35:21.

63 in³
Step-by-step explanation:
Volume = l×w×h
2¼ = 9/4
8 = 8/1
3½ = 7/2
V = 9/4 × 8/1 × 7/2
= 504/8
= 63
So, the answer is 63 in³.
Which statement is correct regarding independent events?
OTwo events are independent if they have no outcomes in common and cannot occur at the same time.
OTwo events are independent if they have outcomes in common and can occur at the same time.
OTwo events are independent if the outcome of the first event does not affect the outcome of the second event.
O Two events are independent if the outcome of the first event affects the outcome of the second event.
Answer:
Two events are independent if the outcome of the first event does not affect the outcome of the second event.
Step-by-step explanation:
two events are independent if the occurrence or outcome of the first event does not affect the outcome or occurrence of the second event.
for example, if you flip a coin the first time and the outcome is a head and you flip a second time and you get a tail. the occurrence of these two event are independent of each other. Thus they are independent events
two outcomes are dependent if the outcome one event is determined by the outcome of the first event.
