Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack. The weight of the blue marlin way 12 times as great of the amberjack. The combined weight of both fish was 273 pounds. How much did each fish weight
Answer:
The weight of the blue marlin = b = 252 pounds
The weight of the amber jack = a = 12 pounds
Step-by-step explanation:
Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack.
Let
The weight of the blue marlin = b
The weight of the amber jack = a
The weight of the blue marlin weigh 12 times as that of the amberjack.
b= 12a
The combined weight of both fish was 273 pounds.
= a + b = 273 pounds
b = 12a
Hence
a + 12a = 273 pounds
13a = 273 pounds
a = 273 pounds/13
a = 21 pounds
b = 12a
b = 12 × 21 pounds
= 252 pounds
Hence:
The weight of the blue marlin = b = 252 pounds
The weight of the amber jack = a = 12 pounds
1/4(B-16)=7

A CD usually sells for $18.00. If the CD is 10% off, and sales tax is 6%, what is the total price of the CD, including tax?
1) Find the inverse of the function below. Use g-1(x) to indicate the inverse 5 points
function. Use SQRT to indicate square root and use parenthesis for
fractions. Example: 9-1(x)=SQRT{(x-2)/3)-6 *
g(x) = 2(x – 3)2 + 4
Your answer
Answer:
g-1(x)=SQRT{(x-4)/2} + 4
Step-by-step explanation:
I assume that the 2 is the exponent so ^ represents exponent
We know your function is g(x)=2(x-3)^2+4
For inverse functions we swap x and y values, note g(x) is like the y value
Isolate for y
y=2(x-3)^2+4
x=2(y-3)^2+4
(x-4)/2 = (y-3)^2
SQRT{(x-4)/2} + 4 = y
Therefore g-1(x)=SQRT{(x-4)/2} + 4

Answer:
Part 3: 9 Dogs
Step-by-step explanation:
It says that the ratio they want you to put it in is dogs/students, so dogs are x, and students are y, so if there are 4 students for every dog, 36 students would require 9 dogs
And if the roles were switched it would be students x, dogs y, and there would be 9 students for 36 dogs :D

(2+3i)(1-2i)
What is the product of the complex number
Answer:
(2+3i)(1-2i) = (8-i)
Step-by-step explanation:
The given complex number is :
Z = (2+3i)(1-2i)
We need to find the product of the complex number
[tex]Z=2(1)+2(-2i)+3i(1)-6i^2\\\\=2-4i+3i-6i^2[/tex]
We know that, [tex]i^2=-1[/tex]
[tex]Z=2-i-6(-1)\\\\=2-i+6\\\\=8-i[/tex]
Hence, the product of the complex number is (8-i).
Y-4=3(x - 1)
Identify slope
and what is an “anchor point”
Find the equation of the line.
Use exact numbers.
y =
x+
Can I please get an explanation :)
Answer:
the equation is in form
y=mx+b where
m=slope
and
b=y-int (the y value for the vertex)
first we look to see what the y value is for the point where x=0 and we can see that it is 5 so b=5
then we look at the slope, slope it the amont of units up then to the side are needed to reach the next point, in this case the line goes up 1 then to the right 1 so the slope is 1/1 (1) so the full equation is
y=x+5
Step-by-step explanation:
What is the slope of the line that passes through the points (-3, -3) and (-9, 5) Write your answer in simplest form.
Step-by-step explanation:
The slope of the line is -4/3.

Answer:
consecutive interior angles equal 180 not equal to each other
Step-by-step explanation:
Answer:
6x− 1 0 = 4 + 4 0
6x-10=4x+40
6x−10=4x+40
Solve
1
Add
1 0
10
10
to both sides of the equation
6 − 1 0 = 4 + 4 0
6x-10=4x+40
6x−10=4x+40
6 − 1 0 + 1 0 = 4 + 4 0 + 1 0
6x-10+{\color{#c92786}{10}}=4x+40+{\color{#c92786}{10}}
6x−10+10=4x+40+10
2
Simplify
Add the numbers
Add the numbers
6 = 4 + 5 0
6x=4x+50
6x=4x+50
3
Subtract
4 4x 4x
from both sides of the equation
6 = 4 + 5 0
6x=4x+50
6x=4x+50
6 − 4 = 4 + 5 0 − 4
6x{\color{#c92786}{-4x}}=4x+50{\color{#c92786}{-4x}}
6x−4x=4x+50−4x
4
Simplify
Combine like terms
Combine like terms
2x=50
5
Divide both sides of the equation by the same term
2x=50
2 /2 = 5 0 /2
\frac{2x}{{\color{#c92786}{2}}}=\frac{50}{{\color{#c92786}{2}}}
22x=250

A right square pyramid is shown. The height of the pyramid is 6 units. The distance from the center of the base of the pyramid to vertex D is 2.5 units, as shown. Find the length of segment AD, in units.
Answer:
Length of side AD is 6.5 units.
Step-by-step explanation:
Let the center of the rectangular base of the given pyramid is O,
From the picture attached,
m∠AOD = 90°
By applying Pythagoras theorem in the right triangle AOD,
AD² = AO² + OD²
AD² = 6² + (2.5)²
AD = √42.25
AD = 6.5 units
Therefore, length of side AD is 6.5 units.

Answer:
midpoint formula is the answer
Help plz quick ASAP I just need help
Answer:
$11.60
Step-by-step explanation:
$9.39
Tax: 3.5%
3.5 ÷ 100 = 0.035 × 9.39 = 0.33
Tax 0.33
9.39 + 0.33 = $9.72
Tip: 20%
20÷ 100 = 0.2 × 9.39 =1.88
tip 1.88
9.72 + 1.88 = 11.60
total $ 11.60
Solve for x. 5x - 29> -34 OR 2x +31 < 29
Answer:
x > -1 or x < -1
Step-by-step explanation:
In this question, you would solve the inequalities.
Solve:
Inequality 1:
5x - 29> -34
Add 29 to both sides
5x > -5
Divide both sides by 5
x > -1
Inequality 2:
2x +31 < 29
Subtract 31 from both sides
2x < -2
Divide both sides by 2
x < -1
Your answer would be: x > -1 or x < -1
