Answer:
x=16
y=23
Step-by-step explanation:
angle (4x+4) and angle (7x-44) are alternate exterior angles which are equal, so we can set up an equation like this to find x:
4x+4=7x−44
calculate it then you'll get x=16
for the next one I'm not really sure how to explain since they are not labeled but,.. since we have the measure 39 we can figure out by using the pairs 'interior angles on the same side of a transversal' and 'vertical angles' that it's equal to 141, so to find y we use the equation
8y-43=141
calculate it and you'll get y=23
Answer:
603.44
Step-by-step explanation:
solution,
radius=4 inches
height=12 inches
volume=?
we know,
volume of cylinder = πr^2h
=22/7×(4)^2×12
=22/7×16×12
=603.44 inches^3#
For each candy bar it would be 3 dollars each so
The four candy bars are a total of 12$ it self plus the 4 dollars for the soft drink so 12+4 is 16
So 3$ each candy bar
Answer:
Lavania observed 39 fruit flies after 6 days of observation
Step-by-step explanation:
Let x be the number of fruit flies on the first day of Lavania's study.
After 6 days she had nine more than five times as many fruit flies as when she began the study.
Five times as many fruit flies as when she began the study = 5x
Nine more than five times as many fruit flies as when she began the study=5x+9
The expression to find the population of fruit flies Lavania observed after 6 days is 5x+9
If she observes 20 fruit flies on the first day of the study, then x=6, then
