Answer: 18 green fish
Step-by-step explanation:
We will write what we know using mathematical equations. Let y be yellow fish and g be green fish. Please note that a percent, 40%, divided by 100 becomes a decimal, 0.4.
-> The aquarium has 6 fewer yellow fish than green fish.
y = g - 6
-> 40 percent of the fish are yellow.
y = 0.4 * (y + g)
[tex]--------------------------------------------[/tex]
Now, we can solve them as a regular system of equations. First, we will find the number of green fish. There are 18, as shown by the work.
y = 0.4 * (y + g)
(g - 6) = 0.4 * ((g - 6) + g)
g - 6 = 0.4 * (2g - 6)
g - 6 = 0.8g - 2.4
g = 0.8g + 3.6
0.2g = 3.6
g = 18
There are 18 green fish in the aquarium.

In a music competition, a participant has to score a total of at least 40 points in the first four rounds combined to move on to the fifth and final round. Glenn scored 4 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Glenn scored in each of the second, third, and fourth rounds if he earned a place in the finals?
a 4 + 3p ≤ 40
b 4 + 3p ≥ 40
c 4p + 3 ≥ 40
d 4p + 3 ≤ 40
Answer:
b 4 + 3p ≥ 40
Step-by-step explanation:
he needs more than 40 points, so we need to pick and answer with a greater than or equal to sign that faces the side with Glenn's points. This leaves b or c for our answers. Glenn played 3 different rounds in which he scored a value represented by the variable p. Additionally, he scored a value of 4 points is given. Therefore, because he scored p in 3 different rounds, p is multiplied by 3 to make 3p. So, 4+3p≥ 40 (answer b) is correct
Answer:
b 4 + 3p ≥ 40

Answer:
30%
Step-by-step explanation:
To express percentage as a fraction, the denominator must be 100.
Given ,
[tex]\frac{18/60}{60/60}\\= \frac{0.3}{1} \\= 0.3 * 100\\= 30%[/tex]
Answer:
1) Percent of skateboards that are longboards is 18÷60 or 30%
2) Number needed for equivalent ratio is 30 longboards
Step-by-step explanation:
1) Percentage= part divided by whole
18÷60 = 0.3
0.3 = 30%
2) Create a proportion, let x = # longboards needed for a equivalent ratio
(18÷60)=(x÷100)
x=30

Answer: C
Step-by-step explanation:
Step 1: Find the unit rate (tomatoes per bowl)
Last time, the ratio was 9:12, or 9 tomatoes for 12 bowls of soup. To finndd the unit ratet, dividde the ffirst given unnit by the 2nd. In this case, tomatoes is the first unit, and bowls is the second. So the unit rate is:
9÷12= 0.75, or 3/4 of a tomato per bowl of soup.
Now, the ratio is 6:8, or 6 tomatoes for 8 bowls of soup. The unit rate is
6÷8= 0.75, or 3/4of a tomato per bowl of soup.
Step 2: Compare
As you can see, the number of tomatoes per bowl of soup hasn't changed at all. So the answer is C.
Hope this helps :)
Answer:
Todays’s soup will taste the same.
Step-by-step explanation:
9 tomatoes for every 12 cups of soup- ratio= 9/12=3/4
6 tomatoes for every 8 cups of soup- ratio=6/8=3/4
They both end in the same ratio, which is 3/4.

John works as a part time waiter in a restaurant. He gets a monthly salary of ₹4,410.Calculate John’s daily, weekly and annual salary.(Take 1 month= 30 days)
1 month is aprox. 30 days, so
To find john's daily salary:
For a month, the salary is 4,410 rupees, so for a day how much?
days salary
30 4,410 (This is how I learnt to solve these kind of problems)
1 ?
Then you crisscross the equation which becomes
4,410/30=147 rupees
To find weekly salary:
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?
You multiply the salary for one day and the number of days: 147×7=1,029 rupees
To find salary for a year (annual):
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 365 days (1 year) how much?
You multiply the salary for one day and the number of days: 147×365=53,655 rupees

Answer:
(d) x = -3/4; y = -3 1/2
Step-by-step explanation:
You are asked for the coordinates of the point of intersection of the lines on the graph. This requires interpolation, because not all grid lines are marked, and the point is not on any grid line.
InterpolationThe idea of "interpolation" is figuring the value of a point that lies between points whose values are known. The answer choices here suggest that we are to interpolate to the nearest 1/4 unit. This requires that you mentally (or actually) divide the space between grid lines into 4 equal sections, and figure where the point lies relative to those divisions.
In the case of the x-coordinate, the first grid line left of the y-axis is not marked, but we notice it lies halfway between x=0 and x=-2. That means we can safely assume that the unmarked vertical grid line has a value of x=-1.
Applicationhorizontal coordinate
The location of the point of intersection of the two lines is horizontally closer to the -1 (unmarked) grid line than it is to the y-axis. Its x-value will be between -1 and 0. The answer choices tell us it is -3/4, consistent with it being about 3/4 of the distance toward -1 from 0.
x = -3/4
vertical coordinate
The location of the point of intersection of the two lines is vertically about halfway between -3 and -4. The answer choices tell us it is -3 1/2.
y = -3 1/2

Answer:
one paperback = 0.6 pounds
one textbook = 3.6 pounds
Explanation:
Let the mass of one paperback be 'p' and one textbook be 't'.
Equation one:
sum of mass = total mass in box
20p + 9t = 44.4Equation two:
20p + 5p + 9t + 1t = 5125p + 10t = 51make 't' subject
10t = 51 - 25pt = 5.1 - 2.5pInsert this into equation one:
20p + 9(5.1 - 2.5p) = 44.4
20p + 45.9 - 22.5p = 44.4
20p - 22.5p = 44.4 - 45.9
-2.5p = -1.5
p = 0.6
The weight of 1 paperback is 0.6 pounds.
The weight of 1 textbook:
t = 5.1 - 2.5p
t = 5.1 - 2.5(0.6)
t = 3.6
The weight of 1 textbook is 3.6 pounds.
