Answer:

exact form:1/3    

Step-by-step explanation:

Law = 99 sq.

L = 2w + 7

---

Law = 99

(2w + 7)w = 99

2ww + 7w = 99

2ww + 7w - 99 = 0

---

the above quadratic equation is in standard form, with a=2, b=7, and c=-99

---

to solve the quadratic equation, plug this:

2 7 -99

the roots of the quadratic are:

-9

5.5

---

the negative root doesn't make sense as a length, so use the positive root:

---

w = 5.5

L = 18

Answer:

y = -2x-5

Step-by-step explanation:

So to calculate the slope the equation is y1-y2/x1-x2. We substitute in two points, let's use (-3,1) as x1 and y1, and (1,-7) as x2 and y2. Put those points in the equation and you get -7-1/1-(-3), which is -2. Now you have y=-2x+b

To get b plug in a pair of points to the equations, say (1,-7). -7=-2(1)+b, solve that and you get b=-5.

So y=-2x-5.

Answer: 7.71666667

Step-by-step explanation:

To find the answer to this problem, you can tell first that the entire rhombus is 360 degrees. And PLA is the same as ANP so ANP is 122 degrees.

360 - 122 + 122 = 116

116 divided by 2 = 58

measure LPN is 58 degrees

and half of 58 is 29

so measure LPA is 29 degrees

In a unit circle, θ=180, the terminal point is (-1,0)

The terminal point is (-1, 0) in a unit circle at ø=180°.

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.

In a unit circle

∵ Ф = 180°

By using the third rule above

Therefore the terminal point is (-1, 0)

Answer:

[tex]\boxed {\boxed {\sf 30 \ Joules}}[/tex]

Step-by-step explanation:

Kinetic energy can be found using the following formula:

[tex]KE=\frac{1}{2}mv^2[/tex]

Where m is the mass and v is the velocity.

The robot has a mass of 60 kilograms and a velocity of 1 meter per second.

[tex]m= 60 \ kg \\v= 1 \ m/s[/tex]

Substitute the values into the formula.

[tex]KE=\frac{1}{2} (60 \ kg) (1 \ m/s)^2[/tex]

Solve the exponent first.

[tex]KE= \frac{1}{2} ( 60 \ kg )(1 m^2/s^2)[/tex]

Multiply the numbers in parentheses.

[tex]KE=\frac{1}{2} ( 60 \ kg*m^2/s^2)[/tex]

Multiply by 1/2 or divide by 2.

[tex]KE= 30 \ kg*m^2/s^2[/tex]

[tex]KE= 30 \ J[/tex]

The robot's kinetic energy is 30 Joules

Answer:

Cost of Wedding cakes = x = $150

Cost of Birthday cakes = y = $40

Step-by-step explanation:

Let us represent:

Cost of Wedding cakes = x

Cost of Birthday cakes = y

Crazy cakes makes wedding cakes and birthday cakes. One week they made 2 wedding cakes and 5 birthday cakes and made $500.

2x + 5y = 500..... Equation 1

The next week they made 1 wedding cake and 7 birthday cakes but only made $430.

x + 7y = 430..... Equation 2

x = 430 - 7y

We substitute 430 - 7y for x in Equation 1

2x + 5y = 500..... Equation 1

2(430 - 7y ) + 5y = 500

860 - 14y + 5y = 500

860 - 500 = 14y - 5y

360 = 9y

y = 360/9

y = $40

Solving for x

x = 430 - 7y

x = 430 - 7(40)

x = 430 - 280

x = $150

Therefore:

Cost of Wedding cakes = x = $150

Cost of Birthday cakes = y = $40

Answer:

Step-by-step explanation:

Use Pythagorean theorem.

Hypotenuse² = base² + altitude²

5)  x²  = 12² + 6²

         = 144 + 36

  x²  = 180

x = √180

x = 13.42 ft

6) 25² = x² + 19²

625 = x² + 361

625 - 361 = x²

x² = 264

x = √264

x = 16.25 m

7)  x² = 7² + 576

        = 49 + 576

        = 625

x = √625

x = 25 in

8)  2.5² = 2²+ x²

6.25 = 4 + x²

6.25 - 4 = x²

x² = 2.25

x = √2.25

x = 1.5 yd

7.25h + 9(20) = 288.75

Multiply 9 by 20:

7.25h + 180 = 288.75

Subtract 180 from both sides:

7.25h = 108.75

Divide both sides by 7.25

h = 108.75 / 7.25

h = 15

Answer:

40 feet

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as isosceles triangle, equilateral triangle, scalene triangle, right angled triangle.

The area of triangle ABC is given as:

Area = (1/2) * AC * BC * sin(C)

But C = 50°, Area = 65.1 ft², BC = 10 ft, AC = b, AB = 13 feet.

Substituting gives:

65.1 = (1/2) * b * 10 * sin(50)

3.83b = 65.1

b = 17 ft

Perimeter of ΔABC = AB + AC + BC = 17 + 13 + 10

Perimeter of ΔABC = 40 feet

Answer:

Perpendicular

Step-by-step explanation:

2x-10y=14

-2x        -2x

-10y=14-2x

/-10      /-10

y=14+1/5

in order for them to be perpendicular the slope has to be the complete opposite to be more exact the number has to be flipped and so does the sign and since -5 was flipped to +1/5 it shows that they would be perpendicular

Answer:

Equation: 2x+1 = 53 (x is 26)

Integers: 26, 27

Step-by-step explanation:

53 is the sum of 2 consecutive integers. That means one of the integers is one larger than the other. This means that twice one integer plus one equals 53, so the equation becomes x + (x + 1) = 53.

x + (x+1) = 53

Combine x and x to get 2x.

2x + 1 = 53

Subtract 1 from both sides to cancel the +1.

2x = 52

Divide both sides by 2 to undo the multiplication by 2.

x = 26

With this we know the first integer is 26. The second is one more than that, so that's 27. So the two integers here are 26 and 27.
