Answer:
She bought 5 pounds of coffee.
Step-by-step explanation:
We are looking for how many pounds so pounds would be your x.
each pound costs $8.62.
You are taking the money she payed for the coffee away from the $70 she received.
Set up your equation
70 - 8.62x = 26.90
Solve for x
Subtract 70 from both sides 70-70 (Cancels out) - 8.62x= 26.90-70
-8.62x = -43.10
Divide -8.62 from each side. -8.62/-8.62(cancels out) x = -43.10/-8.62 (two negative numbers multiplied or divided by each other makes a positive)
x=5
Answer:
27.44 square cm
Step-by-step explanation:
If the length of parallelogram is a and b and angle between side a and b is
.
Then area of parallelogram = 
Given side length 4 cm and 7 cm
angle between them = 100°
value of sin(100°) = 0.98
Thus, area of given parallelogram = 4*7*sin(100°) = 28*0.98 = 27.44
Thus, area of given parallelogram is 27.44 square cm.

Answer:
s(t) = 2.35t and distance covered in 5 minutes = 11.75 feet.
Step-by-step explanation:
A snail travels at a rate of 2.35 feet per minute.
We have to write a rule to describe the function.
If a snail covers the distance of 2.35 feet in a minute then in t minutes distance traveled by the snail will be = 2.35×(t) feet
Now if we define the distance as a function then function will be
S(t) = 2.35(t)
and distance covered by the snail in 5 minutes will be
Distance = 2.35×5 = 11.75 feet
Therefore the function is S(t) = 2.35t and distance covered in 5 minutes is 11.75 feet.
