Given two points (x₁,y₁) and (x₂,y₂) the slope of the line passes through theses points will be:
m=(y₂-y₁)/(x₂-x₁)
We know two points (-5,-1) and (5,11), and the slope will be:
m=(11-(-1)) / (5-(-5))=(11+1)/(5+5)=12/10=6/5

Answer: C. 6/5

Answer:

Lisa bought 9 gallons of ice cream

Step-by-step explanation:

lets take "x" as the gallons of lemonade

if Lisa made purchases worth $34 that is what our equation will e equal to

ice cream:7.5 per gallon

milk: 2.5 per gallon

lemonade: 3 per gallon

since Lisa purchases 4 gallons of milk and 2 gallons of ice cream we will multiply that by the unit money for each food respectively:

7.5(2)+2.5(4)+X=34

SIMPLIFY:

15+10+x=34

15+10=25

25+x=34

25-25+x=34-25

x=9

Lisa bought 9 gallons of ice cream

hope this helps!

A mammoth bone is found to contain roughly 5% of the isotope C-14. Living elephant bones commonly contain about 40% C-14. Given

Elina [12.6K]

Answer:

The mammoth died 17.190 years ago.

Step-by-step explanation:

Given information:

Half-life of C-14 is 5.700 years.

Living elephant bones commonly contain about 40% C-14.

For every 5700 years, the elephant's bones losses a half-life of C-14. And supposing that the living mammoth bones had the same percentage of C-14.

If the mammoth when living has 40%, then:

After 5.730 years, the mammoth bones will contain 20%.
After 11.460 years(2 half-lives), the mammoth bones will contain 10%.
After 17.190 years(3 half-lives), the mammoth bones will contain 5%.

Given that the net of the square pyramid is as shown above, the surface are of the pyramid will be given by:
SA=(number of triangles)*(area of triangle)*(area of square base)
area of one triangle will be:
A=1/2*base*height
A=1/2*0.8*0.75
A=0.3 sq. inches

area of the square base will be:
A=0.75*0.75
A=0.5625
Therefore the surface area will be:
SA=4*0.3*0.5625
SA=0.675 sq. inches
