Answer: 
Step-by-step explanation:
In order to round to the nearest thousandth, you must observe the digit to the right of the digit in the thousandth place and then:
- If it is less than 5, you must round down.
- If it is greater than or equal than 5, you must round up.
In this case, given the number:
You can notice that the digit to the right of the digit in the thousandth place is 9.
Since 
, you must round up. Then:
Finally, to express this as a single-digit times a power of ten, move the decimal point three places to the right. Then you get:
You need 3 trucks of sand that hold 5 tons and 2 trucks that hold 3 tons to move all the sand in one trip
= x(8 -8) +(10 +13)
= 0 +23
= 23
Selection D is appropriate.
Answer:
10 MPH
Step-by-step explanation:
Well since there is 60 minutes in an hour, you can easily take 6 and multiply it by 10 since that will equal 60. 1 mile takes 6 minutes and because we multiplied the amount by 10, we can multiply the amount of miles by 10 as well. If Philip runs at a constant rate for 60 minutes straight, he will be going at 10 MPH. Hope this helps!
Answer:
Part 1) The draw in the attached figure
Part 2) 
Step-by-step explanation:
Part 1) Draw the described circle
The draw in the attached figure
Part 2) What is the measure of angle ABD
step 1
Find the measure of arc AD
Remember that
----> by complete circle
substitute the given values
step 2
Find the measure of angle ABD
we know that
The measurement of the external angle is the half-difference of the arches that comprise
In this problem
The measure of angle ABD is an external angle
so
![m\angle ABD=\frac{1}{2} [arc\ AD-arc\ AC]](https://tex.z-dn.net/?f=m%5Cangle%20ABD%3D%5Cfrac%7B1%7D%7B2%7D%20%5Barc%5C%20AD-arc%5C%20AC%5D)
substitute the given values
![m\angle ABD=\frac{1}{2} [168^o-68^o]=50^o](https://tex.z-dn.net/?f=m%5Cangle%20ABD%3D%5Cfrac%7B1%7D%7B2%7D%20%5B168%5Eo-68%5Eo%5D%3D50%5Eo)
