What is the measure of AngleJHG? A protractor shows line J H G. An arc represents the angle between J H G. H G is horizontal to

the bottom of the protractor and line H J goes up to Point J at 70 degrees. The measure of AngleJHG is degrees.

Answer:  m\angle JHG=70\°

Step-by-step explanation:  

The missing image is attached.

It is important to remember that a protractor is a measuring instrument that is used to measure angles in degrees.

Then, in order to measure an angle in degrees using a protactor, you can follow these steps:

1. You must place the center point of the protractor on the vertex of the angle.

2. Then, you must line up the base line of the proctactor with one side of the angle.

3. Finally, you can read the angle in degrees.

  In this case, you can observe in the image attached that the protractor is placed on the vertex "H" of the angle JHG.

Therefore, based on the explanation shown before, you can identify that the meausre in degrees of the angle JHG is the following:

m\angle JHG=70\°

A square has an area of 75 square meters. Which of the following is closest to the length of a side of the square?
Ilya [14]

The formula for the area of a square of side s is A = s^2.

Then s^2 = A, and s = +√A.

Here, the approx. side length is s = +√(75 m^2), or 8.7 m

What is the recursive rule for the sequence 2, -1, 1/2 , -1/4
Helga [31]

Answer:

a_n=\frac{-1}{2}a_{n-1}

a_1=2

Step-by-step explanation:

The recursive rule is a term defined in terms of other terms in the sequence.

The is a geometric sequence because it has a common ratio.

The common ratio can be found by dividing a term by previous term.

For example, all of these are equal:

\frac{-1}{2}

\frac{\frac{1}{2}}{-1}

\frac{\frac{-1}{4}}{\frac{1}{2}}

They are all equal to \frac{-1}{2}.

So we are saying:

\frac{\text{term}}{\text{previous term}}}=\frac{-1}{2}

More formally:

\frac{a_n}{a_{n-1}}=\frac{-1}{2}.

Multiply both sides by a_{n-1}:

a_n=\frac{-1}{2}a_{n-1}

When doing recursive form, you need to state a term of the sequence (or more depending on the recursive form you have).

So the first term is 2.

So the full thing for the answer is:

a_n=\frac{-1}{2}a_{n-1}

a_1=2

In a triathlon , Jenny swam for 1 hour , biked for 1.75 hours , and ran for 1 hour. Her average biking speed was 2 times her ave
Naddika [18.5K]

Jenny average swimming speed was 2.5 km/h, her average biking speed was 24 km/h and her average running speed was 12 km/h.

<h3>Speed</h3>

Speed is the ratio of total distance travelled to total time taken. It is given by:

Speed = distance / time

Let a represent the average swimming speed, b the average biking speed and c the average running speed.

Her average biking speed was 2 times her average running speed, hence:

  • b = 2c  (1)

Her average running speed was 8 times her average swimming speed. Hence:

  • c = 8a   (2)

Total distance of the triathlon was 55.5 kilometers. Hence:

a * 1 hour + b * 1.75 hour + c * 1 hour = 55.5   (3)

From equation 1, 2 and 3:

a = 2.5, b = 24, c = 12

Jenny average swimming speed was 2.5 km/h, her average biking speed was 24 km/h and her average running speed was 12 km/h.
