24

Step-by-step explanation:

12+12=24

Answer:

First, we should know what the slope-intercept formula is.

Y = MX + B

Where M is your slope, and B is your y intercept.

Let's do the easiest part first, finding our y-intercept. The y-intercept is where the the line intersects the y-axis. In this case, y = 1, because it intersects at (0, 1).

Now we have:

y = mx + 1

Next, we need to calculate the slope, or rise over run. M is presented as a fraction. The numerator is your rise (how high or low it goes), and the denomenator is your run (how far to the right or left it goes).

If it goes LEFT, the number is negative, if it goes RIGHT it is positive.

Also, pretty points are areas in which the line hits an exact coordinate. Using these points is easiest if you want to find the slope of the line.

We can see that the line hits a pretty point every time it goes one coordinate (box) to the right, and up three boxes. What this means it is rises three 3 points, and runs to the right, 1. This is shown as [tex]\frac{3}{1}[/tex]

So let's add that to the equation!

The value of WX will be; (8y³)/(7y+8).

To find the length of WX, we need to substitute the given values of x and simplify the expression:

WX = xy/(2x+16) - xw/(7x-29)

xy/(2x+16) = xw/(7x-29)

Cross-multiplying, we get:

xy(7x-29) = xw(2x+16)

Expanding both sides;

7x²y - 29xy = 2x²w + 16xw

Rearranging terms and factoring out x;

x(7xy - 2xw) = 29xy - 16xw

Solving for x, we get:

x = (29xy - 16xw)/(7xy - 2xw)

Now we can substitute this value of x into the expression for WX to find its value. use the expression WX = xy/(2x+16):

WX = xy/(2x+16)

WX = y(29xy - 16xw)/[2(7xy - 2xw) + 16]

Simplifying the denominator,

WX = y(29xy - 16xw)/[14xy - 4xw + 16]

Finally, we can substitute the given values of xw and xy to get,

WX = y(29xy - 16xw)/[14xy - 4xw + 16] = (8y³)/(7y+8)

Therefore, WX = (8y³)/(7y+8).

Answer:

AT=48.9

Step-by-step explanation:

Formula:

step 1; Aʟ = P ʙᴀsᴇ × Ap

2

step 2; Aᴛ = Aʟ + Aʙᴀsᴇ

Ap= 7cm

Abase= 6.9cm² P️= a + b+ c

length side️=4cm

AL = (4+4+4) × 7

2

= 12 × 7

2

= 84 ÷2

AL = 42

AT = AL + Abase

= 42 + 6.9

AT = 48.9 cm

Answer:

Step-by-step explanation:

Triangle 1   given:  100° , 17 yds,  30 yds

Triangle 2 given: 30 ,17,18

law of cosines: c^2 = a^2 + b^2 − 2ab cos(C)

we'll also  need the formula for a SSS triangle

Cos(C) = a^2 + b^2 - c^2 / 2ab

keeping the above in mind we can now solve both triangles

c = AC for the first triangle

solve law of cosines for what we know

c^2= 17^2 + 30^2 - 2*17*30*Cos(100)

c = 36.96

now use SSS triangle  formula to find the angle C, but c = 17 now , not 36.96, that's b

C = arcCos(17^2+36.96^2-30^2/ 2*17*36.96)

C = 42.24°

now use 180 = 100 +42.24 +A   to solve the last angle

A= 37.75°

Triangle 1 solved

A= 37.75°

B= 100

C = 42.24°

a= 17

b=30

c=36.96

Triangle 2  

given a=17 , b= 18 , c =30

use SSS formula to find one angle, which ever one you want in this case

Cos(C) = a^2 + b^2 - c^2 / 2ab

C = arcCos(17^2+18^2-30^2 / 2*17*18

C= 117.966°

solve for A now

Cos(A) =b^2+c^2-a^2 / 2bc

A = arcCos(18^2+30^2-17^2/2*18*30)

A = 30.03

use 180 again to solve for last angle

180 = 117.966+30.03+B

32.001 = B

Triangle 2 solved

A = 30.03°

B= 32.001°

C= 117.966°

a=17

b=18

c=30

Answer:

23 or 19

Step-by-step explanation:

15+8= 23

23-4= 19

i added 15 and 8 because if you were to flatten the triangle it would be next to the base, so i added it. I subtracted 4 because side C doesn't look like it is is about 23 ft. it could be 20 too.

i am not exactly sure. sorry if you get it wrong. I am so sorry if i got it wrong.

Answer:

51ft, 17ft, 39ft

Step-by-step explanation:

longest = x

2nd = [tex]\frac{1}{3}[/tex]x

3rd = x - 12

P = 107

a + b + c = Perimeter

x + [tex]\frac{1}{3}[/tex]x + x - 12 = 107

[tex]\frac{7}{3}[/tex]x -12 = 107

[tex]\frac{7}{3}[/tex]x = 119

x = 51

[tex]\frac{1}{3}[/tex]x = 17

x - 12 = 39

9514 1404 393

Answer:

  240 ft by 480 ft

Step-by-step explanation:

Area is maximized when the long side is half the total length of the fence. That makes the short side (out from the river) be half the length of the long side.

The fenced field dimensions are 240 feet by 480 feet.

__

You can let x represent the length of the long side. Then the length of the short side is half the remaining fence: (960 -x)/2.

The total area is the product of these dimensions:

  A = x(960 -x)/2

We note that this is the equation of a parabola with zeros at x=0 and x=960. The maximum will be found on the line of symmetry, halfway between the zeros. That is at x = (0 +960)/2 = 480.

The area is maximized for a long-side dimension of 480 feet. The short sides are 240 feet.

Answer:

The field will not fit

Step-by-step explanation:

To find the angle, we will use cosine rule;

c² = (a² + b² - 2abcosC)

C in this case is θ

Thus;

15² = (8² + 20² - 2(8 × 20)cos θ)

225 = (64 + 400 - 320cos θ)

464 - 225 = 320cos θ

cos θ = 239/320

θ = cos^(-1) 0.7469

θ = 41.68°

Thus angle is not less than 40° as recommended. Thus, the field will not fit.

Answer: 0.075

Step-by-step explanation: when you are working with percentages to decimals you want to move the decimal two places to the left. If you are working with decimals and you want to make it a percentage you would move the decimal two places to the right.

Answer:

7.5% = 0.075

Step-by-step explanation:

Whenever you're converting a percentage into a decimal, you multiply the percentage by 100, or move the decimal point two points to the left. So, 7.5% as a decimal is 0.075.
