Answer:
26°
Step-by-step explanation:
same side same angle
the total of angles in triangle is always 180
part a: –2°F > –6°F
part b: the inequality is representing the temperatures of city R and city S, comparing the difference in their temperatures.
part c: (marking city R at –2 on the number line and marking city S at –6 on the number line), using the number line to show the values of the city temperatures, city R is warmer because it is closer to 0 while city S is farther from zero and in the case that these are negative temperatures, the temperature closest to zero is the warmest.
Answer:
a) 91 1/6 gallons
b) 2502 miles
Step-by-step explanation:
You are given a number of miles and a number of gallons for the car. The ratio of these numbers is ...
(261 mi)/(14.5 gal) = 18 mi/gal
We presume this value is constant for this car. Then the questions can be answered by forming and solving a proportion:
a) 1641 miles/(gallons) = 18 mi/(1 gal)
Multiplying by gallons and dividing by 18 mi/gal, we get
1641/18 gal = (gallons) = 91 1/6 gal
It will take 91 1/6 gallons of gasoline for Mary to drive to her friend's house.
___
b) Same deal, but the miles are unknown.
(miles)/(139 gal) = (18 mi)/(1 gal)
Multiplying by 139 gal gives ...
(18 mi)·139 = (miles) = 2502 mi
139 gallons of gasoline will let Mary drive 2502 miles.
Answer:
1. The corresponding sides of the two triangles must be proportional.
Step-by-step explanation:
Option 1, is the only statement that makes GHI = JKL true. If the triangles are congruent, it means that the sides have to be proportional.
