Answer-
The cost of one tetra is $2.5 and one rainbow fish is $8.5
Explanation
Let the cost one tetra be 'x';
Cost of rainbow fish = x + 6;
According to question;
8x + 2(x + 6) = 37;

The expression for r is n(4t-v) and the expression for the width is (P-2l)/2
Subject of formulaThis is a way of representing a variable with another variable.
Given the expression below:
r/n + t = 4v
Making r the subject
r/n = 4v - t
r =. n(4t-v)
Hence the expression for r is n(4t-v)
For the expression
P = 2l + 2w
P - 2l = 2w
2w = P - 2l
w = (P-2l)/2
Hence the expression for the width is (P-2l)/2

In a food court there are people eating hamburgers, burritos & pizza. P(h) = 0. 38 and P(b) = 0. 31. If there are 35 people eating pizza, what is the total number of people in the food court?
Answer should be rounded to the nearest WHOLE NUMBER
The total number of people in the food court eating pizza, burritos, and hamburgers is 113 (Approximate) or (Whole number)
People eating hamburger P(h) =0.38
People eating burritos P(b) = 0.31
Number of people eating pizza = 35
Let's suppose the total number of people is 1
So,
By adding the total number of people eating hamburgers and burritos
= 0.38+0.31
= 0.69
The ratio of the total number of people eating pizza = 1.00 - 0.69
= 0.31
So total number of people eating pizza = 0.31 = 35
By solving :
1 = 35 / 0.31
= (35*100)/31
= 3500/31
= 112.9 (we have to write it down in the nearest whole number)
Here we writing the approximate value of 112.9 = 113 (Approximate)
Hence, the total number of people in the food court in the nearest whole number is 113

Here are the first four terms of a quadratic sequence
3 10 21 36
Work out an expression for the nth term
Please please answers this question ill give u like and mark as brainlist
Answer:
2n² + n
Step-by-step explanation:
Given sequence:
3, 10, 21, 36, ...
Work out the first differences between terms:
[tex]3 \underset{+7}{\longrightarrow} 10 \underset{+11}{\longrightarrow} 21 \underset{+15}{\longrightarrow} 36[/tex]
As the first differences are not the same, work out the second differences.
[tex]7 \underset{+4}{\longrightarrow} 11 \underset{+4}{\longrightarrow} 15[/tex]
As the second differences are the same, the sequence is quadratic and will contain an n² term.
The coefficient of n² is always half of the second difference. Therefore, as the second difference is 4, the coefficient of n² is 2.
To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare with the given sequence:
[tex]\begin{array}{|l|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4 \\\cline{1-5} 2n^2 & 2 & 8 & 18 & 32\\\cline{1-5} \sf Operation & +1 & +2& +3& +4\\\cline{1-5} \sf Sequence & 3 & 10 & 21 & 36\\\cline{1-5}\end{array}[/tex]
Therefore, we need to add n to 2n² to match the sequence.
Therefore, the nth term of this sequence is 2n² + n.

In the diagram, what is the ratio of patterned circles to plain circles?
Four arrays of circles are represented. First array has a plain circle. Second array has 4 patterned circles and 1 plain circle. Third array has 1 patterned circle and 4 plain circles. Fourth array has a plain circle.
The ratio of the patterned circles to plain circles is 6 : 7.
We are given the four arrays of the circles.
In the first array, we have only 1 plain circle.
In the second array, we have 4 patterned circles and 1 plain circle.
In the third array, we have 1 patterned circle and 4 plain circles.
In the fourth array, we have only 1 plain circle.
So, total patterned circles = 5 + 1
Total patterned circles = 6
Total plain circles = 1 + 1 + 4 + 1
Total plain circles = 7
Ratio of patterned circles to plain circles will be given as:
6 : 7
Therefore, we get that, ratio of the patterned circles to plain circles is 6 : 7.

Answer:from least to greatest:
1) g (x)
2) f (x)
3) h (x)
Step-by-step explanation:
Answer:
For f (x):
f (x) = (x + 3) ^ 2 - 2
For x = -1
f (-1) = (-1 + 3) ^ 2 - 2
f (-1) = (2) ^ 2 - 2
f (-1) = 4 - 2
f (-1) = 2
For x = 3
f (3) = (3 + 3) ^ 2 - 2
f (3) = (6) ^ 2 - 2
f (3) = 36 - 2
f (3) = 34

m = 1/2
The function g (x) is:
g (x) = (1/2) x - 3/2
For x = -1
g (-1) = (1/2) (- 1) - 3/2
g (-1) = -1/2 - 3/2
g (-1) = -4/2
g (-1) = -2
For x = 3
g (3) = (1/2) (3) - 3/2
g (3) = 3/2 - 3/2
g (3) = 0
AVR = ((0) - (- 2)) / ((3) - (- 1))
AVR = 1/2
For h (x):
Using the table we have:

D. (78 − 6x)°
The measure of the complement of angle K is (78 - 6x)°. The correct option is D. (78 − 6x)°
Complement of an AngleFrom the question, we are to determine the complement of the given angle measure
From the given information, the measure of angle K (m ∠K) is (6x + 12)°
NOTE: If two angles are complementary, the measures of the angles sum up to 90°
Let the complement of angle K be angle L.
Thus,
∠K + ∠L = 90°
(6x + 12)° + ∠L = 90°
6x° + 12° + ∠L = 90°
∠L = 90° - 12° - 6x°
∠L = 78° - 6x°
∠L = (78 - 6x)°
Hence, the measure of the complement of angle K is (78 - 6x)°. The correct option is D. (78 − 6x)°

Answer:
7
Step-by-step explanation:
hope this works :)
consecutive numbers means 2 numbers next to eachother like 8 and 9 or 3 and 4
product means basically the result of numbers multiplying together, e.g. the product of 8×9 = 72
so if you use trial and error you will find 6 × 7 = 42 and since mav is older she must be 7 years old
Answer:
mav is 7
Step-by-step explanation:
let justin's age be n then mav is n + 1 and the product is
n(n + 1) = 42
n² + n = 42 ( subtract 42 from both sides )
n² + n - 42 = 0 ← in standard form
(n + 7)(n - 6) = 0 ← in factored form
equate both factors to zero and solve for n
n + 7 = 0 ⇒ n = - 7
n - 6 = 0 ⇒ n = 6
since n > 0 then n = 6
mav is n + 1 = 6 + 1 = 7
set up the equation relating the new ratio of broth to solution to the new percentage of broth to solution. 25/60
The new percentage of broth to solution 25/60 is 41.67
Broth, also known as bouillon is a savory liquid made of water in which meat, fish or vegetables have been simmered for a short period of time .It can be eaten alone, but it is most commonly used to prepare other dishes, such as soups.
Commercially prepared liquid broths are available, typically chicken, beef, fish, and vegetable varieties. Dehydrated broth in the form of bouillon cubes were commercialized beginning in the early 20th century.
Broths have been used as a nutrition source for the sick in Great Britain since at least the early 1700s, such as for dysentery patients
Let,
60 represents the 100% of the broth to solution
25 represents the x percentage of the broth to solution
Now,
Solving for the 25 which represents the x percentage of the broth to solution.
25/100 = x/100*
25/60 = x/100*x
25(100) = 60x
x = 2500/60
x = 41.67
