Answer:
[tex]p=\frac{200-5s}{11}[/tex]
Step-by-step explanation:
Let
p ---> the price of one piranhas
s ---> the price of one shark
we know that
The price of one piranhas multiplied by 11 plus the price of one shark multiplied by 5 must be equal to the budget of £200
so
The linear equation that represent this situation is
[tex]11p+5s=200[/tex]
Solve for p
That means ----> isolate the variable p
subtract 5s both sides
[tex]11p=200-5s[/tex]
Divide by 11 both sides
[tex]p=\frac{200-5s}{11}[/tex]
Find the average rate if change in the function f(x) = x^2 +2 over the interval x= -5 to x= -2
If f(x) = x^2 +2 and 5<= x <= -2 :
F(-5)=(-5)^2+2=25+2=27
F(-4)=(-4)^2+2=16+2=18
F(-3)=(-3)^2+2=9+2=11
F(-2)=(-2)^2+2=4+2=6
Average =
(27+18+11+6)/4
=62/4
=15.5

Cousin Hector drove 1,851 miles to the reunion. He lives in Mexico and drove 747 miles through that country to the United States border. How many miles did he drive in the United States?
Answer:
1104 miles
Step-by-step explanation:
Say he lives in a place in Mexico which is at a distance of a miles from the Mexico-America border point and the reunion is at b miles from the same border point, in America.
So the total distance travelled is ( a + b ) miles
( this is just sum of distance travelled in Mexico + that in America )
Given , a=747 and a+b=1851
that implies:
747 + b = 1851
So, b = 1104 miles.
Therefore he has travelled 1104 miles in America,
A survey of all beings on planet Tott found that 12 beings preferred
hab juice to all other juices. If 40 beings were surveyed altogether,
what percent of them preferred hab juice?
Answer:
4.8
12 x 40
100
= 4.8
Step-by-step explanation:
The percentage of beings that preferred hab juice, is 30% of beings preferring hab juice.
The question is asking to find the percentage of beings that preferred hab juice out of a total of 40 surveyed on planet Tott. To do this, we use the basic formula for percentage:
Percentage = (Part / Whole) * 100
In this case, 12 beings out of 40 preferred hab juice. So we have:
Percentage = (12 / 40) * 100 = 0.3 * 100 = 30%
Therefore, 30% of the beings surveyed preferred hab juice.

(4,7) and (5,1) as an equation
Answer:
y = -6x + 31
Step-by-step explanation:
In order for us to make this an equation of the form y = mx + b we have to find the slope.
The formula for slope is rise/ run. The rise is 6 and the run is -1.
So, the slope is 6/-1 or -6.
Our equation is now: y = -6x + b
Substituting 4,7 into the equation we get 7 = -24 + b
So, b = 31.
To check out answers we substitute 5,1 in and it works.

(7,2) and (5,2)
Answer: 0
Step-by-step explanation:
describes a horizontal line
so slope = 0
Answer:
0/2
Step-by-step explanation:
you have to subtract the x's and then then the y's, y is always on top. So, y=2-2/ x= 7-5 making 0/2 When the 0 is on the "top" of the fraction, that would mean that the two y-values are the same.

How do you round to 630 to the nearest hundred
Answer: Here we will tell you what 630 is rounded to the nearest hundred and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the hundred that is nearest to 630.
First, 630 rounded to the nearest hundred is: 600
When rounding to the nearest hundred, like we did with 630 above, we use the following rules:
A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
Step-by-step explanation:
Rounding 630 to the nearest hundred results in 600.
To round the number 630 to the nearest hundred, consider the tens digit of the number.
In this case, the tens digit is 3.
If the tens digit is 5 or greater, you round up to the next hundred.
If the tens digit is 4 or less, you round down to the current hundred.
Since the tens digit in 630 is 3, which is less than 5, you round down.
Therefore, rounding 630 to the nearest hundred results in 600.

Five more than the product of 10 and Maliks height. Use m to represent Maliks height.
Answer: y = 10m + 5
Step-by-step explanation:
Let m be Malik's height , the product of 10 and Malik's height means 10 multiplied by Malik's height, which is 10 x m , which will be

B. 45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Size of each packet of information = 1,500 bytes
Number of packets = P
Number of bytes of information = B
2. Let's answer the questions:
A. How many packets would be needed to transmit 30,000 bytes of information?
P = 30,000 ÷ 1,500
P = 20

Scientists have discovered a new substance with a hydrogen ion concentration of 0.095811180 M. Determine the corresponding pH level for this new substance. Round your final answer 3 decimal places
Answer: 1.018
Step-by-step explanation:
The pH level of a substance indicates the concentration of hydrogen ions ([tex]H^{+}[/tex]) in a solution and is calculated by:
[tex]pH=-log(H^{+})[/tex]
In this case the hydrogen ion concentration is [tex]0.095811180 M[/tex], where
[tex]M=\frac{moles}{volume}[/tex]. Hence:
[tex]pH=-log(0.095811180 M)[/tex]
[tex]pH=1.018[/tex] This means this new substance is acid
Use Pascal’s Triangle to determine the third term of the expansion of (x + 3)4.
Answer:
In the Pascal Expansion of [tex](x+3)^4[/tex] the third term is [tex]54x^2[/tex].
Step-by-step explanation:
Here, the given expression is given as [tex](x+3)^4[/tex]
Now, by the PASCAL'S TRIANGLE EXPANSION:
[tex](a + b)^4 = 1(a)^4 + 4(a)^3b + 6(a)^2b^2 + 4(a)b^3 + 1b^4\\= 1 + 4b + 6a^2 + 4b^3 + b^4.[/tex]
Substituting a = x and b = 3, we get:
[tex](x + 3)^4 = 1(x)^4 + 4(x)^3(3) + 6(x)^2(3)^2 + 4(x)(3)^3 + 1(3)^4\\= x^4 + 12x^3 + 54x^2 + 108x+ 81[/tex]
In the given expansion, the third term is [tex]54x^2[/tex].
Hence, in the Pascal Expansion of [tex](x+3)^4[/tex] the third term is [tex]54x^2[/tex].
Final answer:
The third term is 6 times x squared times 3 squared, which simplifies to 54x².
Explanation:
To use Pascal's Triangle to determine the third term of the expansion of (x + 3)⁴, we first need to look at the row of Pascal's Triangle that corresponds to the exponent 4. This is the fifth row if we start counting from 0 and it reads 1, 4, 6, 4, 1. We use these coefficients for each term of the expansion, which follows the pattern (a + b)ⁿ = C(n,0)*aⁿ + C(n,1)*a⁽ⁿ⁻¹⁾b + C(n,2)*a⁽ⁿ⁻²⁾b² + ... + C(n,n)*bⁿ, where C(n,k) is the binomial coefficient from Pascal's Triangle.
So, the third term in the expansion is given by the third coefficient (counting from 0) from the row, which is 6, multiplied by x raised to power 4 - 2 times 3 squared. Therefore, the third term is 6x²·3², which simplifies to 54x².

Based on the information given in the exercise, you can set up the following system of equations:
[tex]\left \{ {{f=4r} \atop {f+5=3(r+5)}} \right.[/tex]
Use the Substitution Method and substitute the first equation into the second one and then solve for "r":
[tex]4r+5=3(r+5)}\\\\4r+5=3r+15\\\\4r-3r=15-5\\\\r=10[/tex]
Substitute the value of "r" into the first equation and evaluate:
[tex]f=4(10)\\\\f=40[/tex]
A surveyed was conducted at Holy Spirit High school where 50 students were randomly
chosen and asked whether they liked apples or bananas. Of the 50, 36 students said they
like apples, 30 students like bananas and 5 students do not like either apples or bananas.
How many students like both apples and bananas?
Answer:
26
Step-by-step explanation:
50 students were asked, and only 5 said that they did not like apples or bananas.This means that 45 students like either apples or bananas, or both of them. We will call these 45 students, the group of "45".We also know that, between these 45 students there are 36 who like apples and 30 that like bananas. This imply that, 45-36=9 students do not like apples, and 45-30=15 students do not like bananas.Then, there are 15 students within the group of "45" that do not like bananas, and 9 students within the group of "45" that do not like apples. This means that 9+15=24 students within the group of "45" only like bananas or apples. The rest of them, 45-24= 26 like both apples and bananas.63. What is the equation in point-slope form
