Answer:

CBD =31

Step-by-step explanation:

CBD + DBE equal 90 since together they form a right angle

CBD + 59 = 90

Subtract 59 from each side

CBD +59-59 = 90-59

CBD =31

4^2/4^6<br><br> Options:<br> 4^-3<br> 4^3<br> 4^-4<br> 4^4
Vlad [161]
Hello!

The rule regarding the division of exponents states the following:

\frac{ B^{x} }{ B^{y} } = B^{x-y}

Insert any known values into the formula above:

\frac{ 4^{2} }{ 4^{6} } = 4^{2-6}

Simplify the expression:

4^{2-6} = 4^{-4}

We have now proven that \frac{ 4^{2} }{ 4^{6} } is equal to 4^{-4}.

I hope this helps!

Draw a line between the points representing wicket 3 and wicket 9 on the diagram. Then, find the
zalisa [80]

Based on the calculations, the area of a rectangle to the nearest hundredth is equal to 1143.92 ft².

<h3>How to calculate the area of a triangle?</h3>

Mathematically, the area of a triangle can be calculated by using this formula:

Area = 1/2 × b × h

<u>Where:</u>

  • b represents the base area.
  • h represents the height.

By drawing a line between the points representing wicket 3 and wicket 9, we can logically deduce that wicket 2 forms a perpendicular bisector. Thus, the distance between the points representing wicket 3 and wicket 9 is given by:

Distance = 1/2 × 36.77

Distance = 36.77/2

Distance = 18.39 ft.

For the height of this triangle, we would apply Pythagorean's theorem:

h² = 25.02² - 18.39²

h² = 626.0004 - 338.1921

h² = 287.8083

h = √287.8083

h = 16.97 ft.

Area of triangle = 1/2 × b × h

Area of triangle = 1/2 × 36.77 × 16.97

Area of triangle = 311.99 ft².

For area of the rectangle, we have:

Mathematically, the area of a rectangle can be calculated by using this formula;

Area = LW

Area = 36.77 × 31.11

Area = 1143.92 ft².

finlep [7]

Answer:

8 meters

Step-by-step explanation:

First you calculate 10% of 1,015 which is about 101.

Then you add 101 to 1,015 for the second lap distance, which is 1,116

Then you find 11/12 of 1,116 which is 1,023

Finally you subtract 1,023 by 1,015 to get 8.
