The display at an aquarium has sea stars and eels in a ratio of 4:5. It also has 5/8 as many rockfish as sea stars. There are 40 more wolf eels than rockfish. How many Sea stars are there?
64 sea stars in the aquarium.
What is Ratio?Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
Ratio of see stars to eels = S : E = 4:5
E = 5/4(S)
Ratio of rockfish to sea strars = R : S = 5:8
R = 5/8(S)
E = R + 40
5/4(S) = 5/8(S) + 40
Multiply by 8 both the sides
10S = 5S + 320
5S = 320
S = 320/5
S = 64
Hence, 64 sea stars in the aquarium

Answer:
96 m.
Step-by-step explanation:
3 • 2 is used to find the length of the top measurement from the scale we're given, so you multiply 4 by 2 to get it in meters.
4 • 2 = 8.
You do the same to the right side of the bedroom, 3 • 3 = 9, so 4 • 3 = 12.
To find area, you multiply both sides (8 and 12).
8 • 12 = 96.

Describe, in great detail, how you would graph a line that is in slope-intercept form.
Use y=-3x+ 5 as your example.
Hi there!
»»————- ★ ————-««
Please see the explanation below.
»»————- ★ ————-««
Explanation:
Recall the meanings of the variables in the slope-intercept equation.
⸻⸻⸻⸻
[tex]\boxed{\text{\underline{Slope Intercept Form:}}}\\\\y=mx+b\\---------------\\\boxed{\text{Key:}}\\\\\rightarrow \text{m - slope}\\\rightarrow \text{b - y - intercept}[/tex]
⸻⸻⸻⸻
We already have one point given, the y-intercept. The y-intercept of a line when given a slope intercept form equation is: [tex](0, b)[/tex]Using the example, we would graph the point (0,5) as our first point.⸻⸻⸻⸻
To graph the second point, we need to understand the meaning of slope. The slope of a line can be remembered as 'rise over run'.The slope for the given equation is -3. This means we would have to go three units down and then one unit right from the y-intercept. Our new point would be (1,2).⸻⸻⸻⸻
The result should be the graph attached.»»————- ★ ————-««
Hope this helps you. I apologize if it’s incorrect.

Answer:
Step 2: 47
Step 3: 84
Step 4: 114
Step-by-step explanation:
Step 2: The width is 21, and the length is 36.
Sum is addition, so it would be 21 + 36.
21 + 36 = 47
Step 3: 47 x 2 = 84
Step 4: Perimeter is all around, whilst area is on the inside. The length is 21, so it is 21 + 21. 21 + 21 is 42. The width is 36, so it is 36 + 36, which is 72. 72 + 42 = 114.
Using inverse operations is a direct way to solving equations
What is the Golden Rule for solving equations?
Answer:
Do unto one side of the equation, what you do to the other!
Step-by-step explanation:
An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the 'scale' (or equation) balanced so that both sides are ALWAYS equal.
Answer:
Keeping the equation balanced.
Step-by-step explanation:
You need to keep the equation balanced on both sides of the equal sign, like when you need to get rid of the number 4 on one side you have to do the same thing on the other side.

Answer:
26%
Step-by-step explanation:
26 out of 100 orange squares are coloured in. To find the percentage of the shape you take:
Number of coloured sqaures / Total number of squares x 100 = %
= (26/100) x 100
= (0.26) x 100
= 26%
Question:
A running club keeps track of the number of hours each person has trained for a race and the length of time it takes the person to run the race. A scatter plot is graphed with the x-axis indicating the number of hours a runner has trained and the y-axis indicating the time, in minutes, it took to run the race. The equation y = 60 - 0.5x is used as the line of best fit of the data. What does the slope of the equation represent?
options:
a
Runners will decrease their race time by 2 minutes for every 1 hour they have trained.
b
Runners will increase their race time by 2 minutes for every 1 hour they have trained.
c
Runners will increase their race time by 1 minute for every 2 hours they have trained.
d
Runners will decrease their race time by 1 minute for every 2 hours they have traine
The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.
What is scatter plot?A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.
Here, we have,
We are given the scatter plot which shows the distance he has run and the time it took for each run.
We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?
One way to predict the time is by drawing a line that best fits the given data.
As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.
Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

Step-by-step explanation:
9. 9y = 72
Divide each side by 9
9y/9 = 72/9
y = 8
10. 3n = 63
Divide each side by 3
3n/3 = 63/3
n = 21
11. 4 = v/11
Multiply each side by 11
4*11 = v/11*11
44 = v
12. c/7 = 5
Multiply each side by 7
c/7*7 = 5*7
c = 35
What is the area of the figure below?
Answer:
68 in
Step-by-step explanation:
Because the area of the squares is 3 x 3 = 9 and because there are two squares it is 18. The area of the central figure is 50 because i divided it into 4 triangles and 2 rectangles, each rectangle is 15 in and each triangle is 5 in so 15 x 2 = 30, 5 x 4 = 20 and 30 + 20 + 18 = 68

Answer:
448
Step-by-step explanation:
I = Prt where I is the interest P is the principle r is the rate and t is the time
I = 400 * (.02) * 6
I = 48
The amount in the account is the interest plus the original amount
400 +48
448
Answer:
$ 448
Step-by-step explanation:
amount that Elena deposit (P) =$ 400
rate of interest (R)=2%
time (T)=6 years
formula to find interest is
Interest = PTR/100
=$400*6*2/100
=$4800/100
=$48
Total amout she receives after 6 years is
Amount = Interest + Principal
=$48 + $400
=$448

A sentence (sometimes also called a formula) is simply a string of characters or symbols.
E.g., “sin2 x + cos2 x = 1” is a sentence as is “5 + 4”.
A statement is a sentence that is definitely either true or false.
What are the Euclidean postulates?A straight line segment may be drawn from any given point to any other. A straight line may be extended to any finite length. A circle may be described with any given point as its center and any distance as its radius. All right angles are congruent.
What are the 5 postulates described by Euclid?Euclid's postulates were: Postulate 1: A straight line may be drawn from any one point to any other point. Postulate 2:A terminated line can be produced indefinitely. Postulate 3: A circle can be drawn with any center and radius. Postulate 4: All right angles are equal to one another.

What is the value of x and y?
Answer:
[tex] x=\boxed{2} [/tex]
[tex] y=\boxed{4}[/tex]
Step-by-step explanation:
[tex] \begin{cases} y= 6x-8... (1)\\\\y=-3x+10...(2)\end{cases} [/tex]
From equations (1) & (2), we find:
6x - 8 = - 3x +10
[tex] \therefore 6x+3x = 8+10[/tex]
[tex] \therefore 9x = 18[/tex]
[tex] \therefore x =\frac{18}{9}[/tex]
[tex] \therefore x = 2[/tex]
Plug x = 2 in equation (1)
y = 6(2)-8 = 12-8 =4
So,
