Answer:

(x, y) = (-5/13, -41/13)

Step-by-step explanation: (Assuming the following corrections:)

y = 3x-2

-7x-2y = 9

-7x-2(3x-2) = 9

-7x-6x+4 = 9

-13x = 5

x = -5/13

y = -5/13(3) - 2

y = -15/13 - 2 = -41/13

Answer:

24 kilograms of catfish

Step-by-step explanation:

Take the percentage of catfish as a decimal or fraction and multiply it by the total amount of fish caught. The percent of catfish is 40% which is the same thing as 0.4. Multiply that by the total 60 kg of fish to get 24 kg of catfish.

Answer:

x=14/5

Step-by-step explanation:

Group like terms

2x+8x+7=35

Add similar elements: 2x+8x=10x

10x+7=35

Subtract 7 from both sides:

10x+7−7=35−7

Simplify

10x=28

Divide both sides by 10

10x/10 =28/10

Simplify:

x=14/5

Answer:

[tex]2x+7+8x=35[/tex]

[tex]2x+8x+7=35[/tex]

[tex]10x+7-7=35-7[/tex]

[tex]10x=28[/tex]

[tex]\cfrac{10x}{10}=\cfrac{28}{10}[/tex]

[tex]x=\cfrac{14}{5}[/tex]

or

[tex]x=2.8[/tex]

Using quadratic function concepts, it is found that:

The height of the rocket after x seconds is given by:

[tex]h(x) = -5x^2 + 10x + 20[/tex]

Which is a quadratic function with coefficients [tex]a = -5, b = 10, c = 20[/tex].

The maximum height will be a reached at a time of [tex]x_v[/tex], and will be of [tex]y_v[/tex], considering the vertex given by:

[tex]x_v = -\frac{b}{2a}[/tex]

[tex]y_v = -\frac{\Delta}{4a}[/tex]

[tex]\Delta = b^2 - 4ac[/tex]

Then:

[tex]x_v = -\frac{10}{2(-5)} = 1[/tex]

[tex]\Delta = 10^2 - 4(-5)(20) = 500[/tex]

[tex]y_v = -\frac{500}{4(-5)} = 25[/tex]

Thus:

It hits the ground when [tex]h(x) = 0[/tex], thus:

[tex]-5x^2 + 10x + 20 = 0[/tex]

[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-10 + \sqrt{500}}{2(-5)} = -1.2[/tex]

[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{-10 - \sqrt{500}}{2(-5)} = -3.2[/tex]

We want the positive root, so, it takes approximately 3.2 seconds for the rocket to hit the ground.

Answer:

x = 10

Step-by-step explanation:

The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles. The two non-adjacent interior angles opposite the exterior angle are sometimes referred to as remote interior angles.

In the given problem, the exterior angle is < JUV, and its corresponding remote interior angles are < V and < W.

Establish the following equation according to the exterior angle theorem:

< V + < W = < JUV

88° + (5x + 1)°  = (14x - 1)°

Solve for x algebraically:

88° + 5x + 1  = 14x - 1

89 + 5x = 14x - 1

89 + 1 + 5x = 14x - 1 + 1

90 +  5x = 14x

90 + 5x - 5x = 14x - 5x

90 = 9x

90/9 = 9x/9

10 = x

Therefore, the value of x = 10.

Answer:

x = [tex]\frac{5}{4}[/tex]

Step-by-step explanation:

3(x - 5) - 5x = - 25 + 6x ← distribute parenthesis and simplify left side

3x - 15 - 5x = - 25 + 6x

- 2x - 15 = - 25 + 6x ( subtract 6x from both sides )

- 8x - 15 = - 25 ( add 15 to both sides )

- 8x = - 10 ( divide both sides by - 8 )

x = [tex]\frac{-10}{-8}[/tex] = [tex]\frac{5}{4}[/tex]

Step-by-step explanation:

use a little imagination.

the whole thing is a combination of churches and half- circles.

and you know the formula for the area of a circle ?

A = pi×r²

so, the only difficulty is to find the circles and then the radius of each involved circle.

when you look at the picture, the shaded area is almost identical to the lower half of the main circle.

2 bumps "look" over into the other side, but one equally sized bump is removed from this lower half.

so, as a first step we will calculate the area of the lower half of the main circle.

the diameter is 24 m, so the radius is half of that : 12m

the area of the large circle is therefore

pi×12² = 144×pi m²

since we only need the (lower) half, we divide this by 2 :

144×pi / 2 = 72×pi m²

the bumps up and down are actually half-circles too. just of smaller circles.

since AB = BC = CD, we know each of these lines are 1/3 of the main diameter AD.

so, the diameter of the smaller circles is 24/3 = 8 m

and their radius is half of that = 8/2 = 4m

the area of such a small circle is therefore

As = pi×4² = 16×pi m²

and a small half-circle area is then

16×pi / 2 = 8×pi m²

so, for the full shaded area I need to take the large half-circle and add 2 small half-circles, and then subtract 1 small half-circle.

so, in total I only need to add 1 small half-circle.

Ashaded = 72×pi + 8×pi = 80×pi m²

okay so..

Given

<2 = 110°

• <2 = <4 so <4 = 110°

Step-by-step explanation:

Solution

• <4 is equal with it's front facing angle(the angle next to <1) let's call that angle <x

<4 = <x = 110°

<x + <1 = 180°

110° + <1 = 180°

<1 = 180° - 110°

<1 = 70°

• <4 + <3 = 180°

110° + <3 = 180°

<3 = 180° - 110°

<3 = 70°

Rate of return

[tex]\\ \sf\longmapsto \dfrac{123}{7}[/tex]

[tex]\\ \sf\longmapsto 17.5\%[/tex]

The rate of return on the stock will be equal to 17.3%.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Total number of stocks = 35

Purchase price of each stock = $20

Then, the price of 35 stocks will be,

35 × $20 = $700

The selling price of all stocks = $815

Also, the commission for selling is $6.

So, the extra money earned will be,

815 - 700 + 6 = 115 + 6

= $121

So, the rate of return from the original price will be,

= 121/700 × 100

= 12100/700

= 17.3%
