Answer:

If a parallelogram has at least one 90 degree angle then its opposite angle is equal and also = 90 degrees.

The 2 remaining opposite angles add up to 180 degrees and since they must be equal, they must be 90 degrees each.

So, we have a quadrilateral with four 90 degree angles and is therefore a rectangle OR it could possibly be a square.

mixer [17]

Answer:

6 tenth

Step-by-step explanation:

Place values of numbers are the values such number represents in a given number. Example, we have tens, hundreds units etc.

To obtain the value of 6 in 3.651 we have to find the decimal place equivalent of 6 in the expression.

6 in 3.651 = 6/10

Sandra sets the cruise control in her car to 69 miles per hour when she goes on road trips. Which equation can be used to find h

jarptica [38.1K]

Answer: $h=\frac{m}{69}$

Step-by-step explanation:

For this exercise is necessary to remember the following formula:

$V=\frac{d}{t}$

Where "V" is the speed, "d" is the distance and "t" is the time.

In this case you must solve for the time, then:

$tV=d\\\\t=\frac{d}{V}$

Based on the information provided in the exercise, you can identify that:

$V=69\\\\t=h\\\\d=m$

Therefore, knowing this, you can make the substitution into the formula $t=\frac{d}{V}$ .

Through this procedure you get that the equation that can be used to find the amount of hours "h" that it will take Sandra to drive "m" miles at her constant speed, is:

$h=\frac{m}{69}$
