A Japanese beetle has length between 0.3 and 0.5 inches.Find two lengths that are within the given span. Write them as fraction
Wittaler [7]
<span>A Japanese beetle’s length are equals to
=> 0.3 inches
=> 0.5 inches

Now let’s find the length that is between the span of the two given length:
But before that let’s convert the 2 given numbers in decimal points to fraction:
=> 0.3 = 3/10
=> 0.5 = 5/10

Find the fraction between the given 2 numbers:
=> 0.3
=> 0.4
=> 0.5

Therefore the number we are looking 0.4
=> 0.4 = 4/10
Now, we have the complete length of Japanese beetles, the 0.3, 0.4 and 0.5</span>

The equation cos(35o) =a/25 can be used to find the length of . What is the length of bc? Round to the nearest tenth
poizon [28]
The equation cos (35°) = can be used to find the length of one side of a triangle It could be the length of the altitude or the length of the base depending of which the angle 35° was assigned. But in order for us to proceed with the calculation, we also need the length of the hypotenuse since cos (x) are<span> equal to the length of the adjacent side divided by the hypotenuse. The answer is 20.5 </span>

Please help me<br><br> In circle Y, what is mTU?<br><br> 59°<br> 67°<br> 71°<br> 118°
yawa3891 [41]

we know that

The measure of the angle formed by 2 chords that intersect inside the circle is \frac{1}{2} the sum of the chords' intercepted arcs. (Angles of intersecting chords theorem)

so

in this problem

63=\frac{1}{2}*(SR+TU)\\ \\ 63=\frac{1}{2}*(55+TU)\\ \\ TU=63*2-55\\ \\ TU=126-55\\ \\ TU=71

therefore

the answer is

The measure of the arc TU is equal to 71degrees
