The ratio of rainbow trout to mackinaw released into a lake was 4:7. A total of 682 fish were released. How many were mackinaw?
Answer:
There are 450 trout in the lake.
B - brown trout;
R - rainbow trout.
B : R = 6 : 9 = 2 : 3
B = 2 t
R = 3 t
2 t + 3 t = 5 t
5 t = 450
t = 450 : 5
t = 90
R = 3 * 90 = 270
Answer:
There are 270 rainbow trout in the lake.

You are having a movie marathon. Each movie lasts about 12 hours.
If you want to watch 4 movies, how long will your movie marathon last?
Answer:
Your movie marathon will last 6 hours.
Step-by-step explanation:
This question can be solved using a rule of three.
Each movie lasts hours. How much do 4 movies last?
So
1 movie - 1.5 hours
4 movies - x hours
x = 4*1.5 = 6
Your movie marathon will last 6 hours.
Answer:
48 hours or 2 days
Step-by-step explanation:
There are 4 movies
Each movie lasts 12 hours
4 x 12 or 12 x 4 equals 48
The marathon lasts 48 hours

Evaluate (y - 9) + (3 + x), when y = 15 and x = 5
Answer:
14
Step-by-step explanation:
It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5'.
So we'd put 15 in y's place. It'll look like this (15 - 9).
Then we'd put 5 in x's place. It'll look like this (3 + 5).
You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!

Answer:
b. 55°
Step-by-step explanation:
Complementary angles have a sum of 90°.
∠ABC +∠CBD = 90° . . . . . . the given relation
∠ABC + 35° = 90° . . . . . . . . . substitute the given value
∠ABC = 55° . . . . . . . . . . . . . . subtract 35° from both sides
∠ABC = ∠EBF = 55° . . . . . . vertical angles are congruent
HELP PLEASE ! Write an equation of a line that passes through the point (4, 3) and is perpendicular to the graph of the equation y= -1/3x+4
Answer:
y = 3x - 9
Step-by-step explanation:
✔️Find the slope of the line perpendicular to the given graph of equation:
A line that is perpendicular to the graph of the equation y = -⅓x + 4, will have a slope value that is the negative reciprocal of the slope of the graph of the given equation.
The slope of y = -⅓x + 4 is -⅓.
Negative reciprocal of -⅓ = 3
Slope of the line (m) = 3
✔️Find the y-intercept (b):
Substitute (x, y) = (4, 3) and m = 3 into y = mx + b
3 = 3(4) + b
3 = 12 + b
3 - 12 = b
-9 = b
b = -9
✔️Write the equation:
Substitute m = 3 and b = -9 into y = mx + b
y = 3x + (-9)
y = 3x - 9

A surfboard that has a regular price of $150 is on sale at a 40% discount. What is the sale price with a 9% tax?
Answer:
$98.10
Step-by-step explanation:
150 decrease 40% =
150 × (1 - 40%) = 150 × (1 - 0.4) = 90
90 increase 9% =
90 × (1 + 9%) = 90 × (1 + 0.09) = 98.1

Answer:
x=20, y=100
Step-by-step explanation:
3x+2x=7x-40
5x=7x-40
2x=40
x=20
7x-40=y
140-40=y
100=y
y=100
According to the exterior angle theorem, the two remote interior angles are equal to the exterior angle. This is why we set 3x+2x equal to 7x-40.
According to the vertical angles theorem, two angles that are opposite and formed by two intersecting straight lines are equal. This is why we set 7x-40 equal to y.
Because we already knew that x was 20, we could put it into our equation. (7*20)-40=y.

Given :
△AFB≅△DECSince triangle AFB is congruent to triangle DEC their corresponding parts will be equal.
Which means :
m∠AFB = 37°m∠ABF = 90°Sum of all angles of a triangle = 180°
Measure of ∠CDE :
[tex] = \tt180 - 37 + 90[/tex]
[tex] = \tt180 - 127[/tex]
[tex] = \tt53[/tex]
Thus, the measure of angle CDE = 53°Then, the measure of angle BAF = 53°Therefore, m∠A = 53°
My answer :[tex]\hookrightarrow\boxed{\color{plum}\bold {\tt \: \bold{m∠A = 53°}}}[/tex]

In a certain year, a magnitude 7.8 earthquake struck California. In another year, a magnitude 5.8 quake struck Kansas. How many times as intense as the Kansas quake was the California quake?
Answer:
The California quake was 1.34 times as intense as the Kansas quake.
Step-by-step explanation:
To find how many times as intense as Kansas (K) quake was the California (C) quake first, we need to find the ratio of intensity (I) between those earthquakes:
[tex] \frac{I_{C}}{I_{K}} = \frac{7.8}{5.8} = 1.34 [/tex]
Now, by multiplying the above number for the intensity of the Kansas quake we should have the intensity of the California quake:
[tex] I_{K} = 1.34*5.8 = 7.8 [/tex]
Therefore, the California quake was 1.34 times as intense as the Kansas quake.
I hope it helps you!
Solve for x. What is the value of
Pls help me
Answer
x = 21
HOS = 68
Explanation
The arrows beside x point to 12 and 6, which is a straight angle. Straight angles always add up to 180 degrees.
So that means 3x+5 plus 5x+7 must equal 180 degrees.
3x+5+5x+7 = 180
Combine like terms.
8x+12 = 180
Subtract 12 from both sides.
8x = 168
x = 21
But BE CAREFUL.
The problem is asking for the angle HOS.
To do this, just substitute what you got for x into the expression.
3(21)+5 = 68
The value of HOS is 68 degrees.
