Answer:

0.75 or 3/4 = r

Step-by-step explanation:

To figure out the value of r, you must find the square root of both sides, which would cancel the square. Now the equation would be 4r = 3. From there, you can divide both sides by 4 to get r by itself. so now, the equation is r=3/4 or 0.75

Hey there! :D

Pay attention to the given angles.

We know that a circle is equal to 360 degrees.

We know two angles, and the other 2 are the same measure.

170+44= 214

Subtract that from 360, since that is what the circle equals.

360-214= 146

Divide that by two, since there are 2 equal angles left.

146/2= 73

<DOB= 73 degrees.

You were correct, so good work!

I hope this helps!

Describe the relationship between the values of the given digit. The 4s in 44,000

Juli2301 [7.4K]

Answer:

one of them has a value that is ten times the value of the other one

Step-by-step explanation:

The most-significant 4 has a value of 40,000.

The least-significant 4 has a value of 4,000.

The most-significant 4 has a value that is 40,000/4,000 = 10 times that of the least-significant 4.

The basis of a place-value number system is that the value of a digit is multiplied by the value of the base when the digit is placed one more place to the left in the number. That is, the digit in the 5th place to the left of the decimal point will have a value that is 10 times the value of the same digit in the 4th place to the left of the decimal point.
