The measure of angle Jkl can be represented using the expression 3x+5 What is the Degree of JKL

Answers

Answer:

$65^\circ$

Step-by-step explanation:

It is given that the measure of angle JKL can be represented by $(3x+5)$ .

And from the figure we can see that the measure of angle JKL is,

$(45^\circ+x^\circ)$

Both the measures must be equal, hence equating both the angles we get,

$(3x+5)=45+x$

Solving for 'x' we get,

$3x+5=45+x$

$3x-x=45-5$

$2x=40$

$x=(40)/(2)$

$x=20$

Putting the value of 'x' we can calculate the measure of angle JKL,

$45^\circ+x^\circ=45^\circ+20^\circ=65^\circ$

Therefore, the measure of angle JKL is, $65^\circ$ .

What is 16 1/4 as a regular fraction

Answers

Answer:

16 times 4 equals 64 then plus 1 equals 65 ANSWER: 65

Final answer:

The mixed number 16 1/4 can be converted into a regular fraction by multiplying the whole number by the denominator and adding the numerator. This gives us 65/4.

Explanation:

The mixed number 16 1/4 can be converted into a regular fraction (also known as an improper fraction) by following these steps:

Multiply the whole number part (16) by the denominator of the fraction part (4). This will give you 64.
Add the result to the numerator of the fraction part (1). This will give you 65.
Write your answer over the denominator. So, 16 1/4 as an improper fraction is 65/4.

So, when expressed as a regular fraction, 16 1/4 becomes 65/4.

Bill measures the circumference of a circular fish pond to be 28 ft. What is the diameter of the fish pond, rounded to the nearest foot? Use 3.14 to approximate pi.

Answers

it would be 9 ft. using the knowledge of $\pi$ times the diameter ( $\pi$ equals aprox. 3.14) equal the circumference of a circle, and since we know the circumference, we need to divide that by $\pi$ to get the diameter.

equation: 28/3.14=8.913
rounding that would bring it to 9 ft.
