7. Current greenhouse gas emissions are about 5 billion metric tons per year in the United States. If this amount were cut by
1% each year for 10 years compounded annually, what would
be the final rate for greenhouse gas emissions?

In 2017, the United States emitted 6.5 billion metric tons of greenhouse gases (CO2e). Carbon dioxide accounted for the largest percentage of greenhouse gases (82%), followed by methane (10%), nitrous oxide (6%), and other greenhouse gases (3%).

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.
