177.8 centimeters.

<h3>What is the formula for cos θ?</h3>
  • The symbol for it is Cosθ, and it has the following form: adjacent/hypotenuse = cosθ. In other words, it divides the length of the hypotenuse by the length of the neighboring side, which is the side next to the angle (the longest side of a right triangle).
  • When working with right-angled triangles, the Cos Theta Formula is particularly helpful. The Cosine of an angle in a right triangle is always equal to the hypotenuse's length divided by the length of the neighboring side. This makes it an excellent tool for resolving Cosine-related issues.

The shortest distance between the tip of the cone and its rim:

cos θ= base/Hypotenuse

cos 77°=\frac{40}{H}

0.22495=\frac{40}{H}

H=177.8

The shortest distance between the tip of the cone and its rim exits 51.11cm.

<h3>What is the shortest distance between the tip of the cone and its rim?​</h3>

If you draw a line along the middle of the cone, you'd finish up with two right triangles and the line even bisects the angle between the sloping sides. The shortest distance between the tip of the cone and its rim exists in the hypotenuse of a right triangle with one angle calculating 38.5°. So, utilizing trigonometry and allowing x as the measurement of the shortest distance between the tip of the cone and its rim.

Cos 38.5 = 40 / x

Solving the value of x, we get

Multiply both sides by x

$\cos \left(38.5^{\circ}\right) x=\frac{40}{x} x

$\cos \left(38.5^{\circ}\right) x=40

Divide both sides by $\cos \left(38.5^{\circ}\right)$

$\frac{\cos \left(38.5^{\circ}\right) x}{\cos \left(38.5^{\circ}\right)}=\frac{40}{\cos \left(38.5^{\circ}\right)}

simplifying the above equation, we get

$x=\frac{40}{\cos \left(38.5^{\circ}\right)}

x = 51.11cm

The shortest distance between the tip of the cone and its rim exits 51.11cm.

What is a number mulitplyed by 8 and added by 6?
HACTEHA [7]
Xy = 8
x + y = 6

     x + y = 6
x - x + y = -x + 6
           y = -x + 6

                                 xy = 8
                       x(-x + 6) = 8
                   x(-x) + x(6) = 8
                        -x² + 6x = 8
                   -x² + 6x - 8 = 0
     -1(x²) - 1(-6x) - 1(8) = 0
              -1(x² - 6x + 8) = 0
                          -1           -1
                    x² - 6x + 8 = 0
             x² - 4x - 2x + 8 = 0
 x(x) - x(4) - 2(x) + 2(4) = 0
           x(x - 4) - 2(x - 4) = 0
                  (x - 2)(x - 4) = 0
      x - 2 = 0    or    x - 4 = 0
        + 2 + 2             + 4 + 4 
           x = 2       or      x = 4

   x + y = 6
   2 + y = 6
 - 2        - 2
         y = 4
   (x, y) = (2, 4)

           or
    x + y = 6
    4 + y = 6
  - 4        - 4
          y = 2
    (x, y) = (4, 2)

The two numbers that add up to 6 and multiply to 8 are 4 and 2.

1. Scientific Notation and Percent. (Based on the ideas in Objective 1 and Objective 4.) 6 points
vlabodo [156]

Answer: 1.715*10^{12} skin cells were not burned.

Step-by-step explanation:

<h3><u> The complete exercise is: Two percent of Sennie's skin cells were burned when she escaped from a fire. If 3.5*10^{10} of her skin cells were burned then, how many skin cells were not burned?​</u></h3><h3 />

Let be "x" the number of Sennie's skin cells that were not burned when she escaped from the fire.

According the the data given in the exercise, you know that 2% represents 3.5*10^{10} of Sennie's skin cells that were burned. This means that the percent of her skin cells that were not burned is:

100\%-2\%=98\%

With this information you can write the following proportion:

\frac{3.5*10^{10}}{2}=\frac{x}{98}

Solving for "x", you get:

(98)(\frac{3.5*10^{10}}{2})=x\\\\x=171.5*10^{10}

To express the result in Scientific notation, the decimal point must be after the first digit; then you must  move the decimal point two places to the left:

x=1.715*10^{12}
