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

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:

123.8 cm

Step-by-step explanation:

well we know that STUV is a parallelogram (given)

so by properties of a parallelogram we know that opposite sides are congruent (in other words equal)

so we have that

VU=TS

and we know that VU=123.8 cm (given)

so TS=123.8

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).

Answer:

a(n-1)+d

d=5

The anser is A

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

x = 140

Answer:

140° ?

Step-by-step explanation:

Since Angle CAD is 20°, and CEA is 180°. Angle CED has to equal to 20°. I added angle CAD to CED and got 40°. Then I subtracted 40 from 180 and got 140 °.

Hope this Helps!!!

Answer:

Step-by-step explanation:

To write an equation that is perpendicular to a given line, take the negative reciprocal of the given slope. the given slope is 4/3, so the negative reciprocal is -3/4.

Using slope-intercept form of a linear equation, y=mx+b substitute in -3/4 for "m" the slope.

y=-3/4x+b

Now you need to "b" the y-intercept using the given point (-4,-1). Substitute the values in the equation. -1=-3/4(-4)+b simplify

                           -1= 3 + b    subtract 3 for both sides

                           -4=b

         substitue -4 for b.   Now you have    y= -3/4x - 4    this is your answer.

Answer:

The answer would be option 2) 51 miles/3 gallons.

Step-by-step explanation:

First, every 17 miles needs 1 gallon. If you add 17 more miles, it'll be 34 miles and you'll need a 2nd gallon, so you can already eliminate options 3 and 4. If you add another 17 miles and a gallon, it'll give you 51 miles 3 gallons. Option 1 would not be the answer because if you did 3/51, you'll get a whole different answer in decimals. So the only other option to choose from is option 2.

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

Answer:

50 and 80 or 65 and 65

Step-by-step explanation:

two angles in an isosceles are the same.

Answer:

2 seconds later

Step-by-step explanation:

Since the required equation is lacking, let the equation modeled by the height be expressed as y = -16t² + 64

The ball hits the ground at y =0. Substitute y = 0 into the expression and find t;

Since y = -16t² + 64

0 =  -16t² + 64

16t² = 64

t² = 64/16

t² = 4

t = ±√4

t = 2 and -2

Time cannot be negative, hence the ball hits the ground 2 seconds later.

Note that the equation used was assumed. Similar solution can be applied for any given equation.

Answer:

  9

Step-by-step explanation:

  (f ◦ g)(3) = f(g(3))

Each of the coordinate pairs for g correspond to ...

  (x, g(x))

Then g(3) can be found by looking for the pair that has 3 in the first location. That ordered pair is ...

  (3, 4)

so we know that g(3) = 4.

Now, we know that f(g(3)) = f(4). This tells us to look for the ordered pair in the f relation that has 4 as its first value. That ordered pair is ...

  (4, 9)

so we know that f(4) = 9.

__

In summary, ...

  (f ◦ g)(3) = f(g(3)) = f(4) = 9

from both sides of the equation

6 = 4 + 5 0

6x=4x+50

6x=4x+50

6 − 4 = 4 + 5 0 − 4

Answer:the original price is $680

Step-by-step explanation:

1/4(x)=170

4×1/4(x)=4×170

x=$680

The original price of the nightstand is $680.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Krystal bought a nightstand on sale for $170, which was one-fourth of the original price.

Let the original price of nightstand be x.

Now, 1/4x =170

x=170×4

x=$680

Therefore, the original price of the nightstand is $680.
