You are a civil engineer designing a bridge. The walkway needs to be made of woodes planks. You are able to use either Saka spruce planks (which weigh 3 pounds cach) wood planks which weight 4 pounds each or a combination of both The total weight of the planks must be between 600 and 900 pounds in order to meet safety code " Sitka spruce planks cout RM25 beach and basswood planks cost RM3 75 each, how many of each plank should you use to minimize cost while still meeting building code?

step-by-step explanation:

depending on others is critical to survival. my source is apex!

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
