B 20°C20°C
C 30°C30°C
D 80°F
The difference in temperature between 50°C and 30°C is 20°C.
Therefore, the correct answer is B) 20°C.
Jim is climbing a mountain that has a base 150 feet above sea level. If he climbs 233 feet then descends into a cave 64 feet, how far above sea level is Jim?
Responses
A 86 feet86 feet
B 169 feet169 feet
C 214 feet214 feet
D 319 feet
To calculate how far above sea level Jim is, we need to subtract the distance he descends into the cave (64 feet) from the sum of the distance he climbs (233 feet) and the base of the mountain (150 feet):
150 + 233 - 64 = 319 feet.
Therefore, Jim is 319 feet above sea level.
Hence, the correct answer is D) 319 feet.
The regular price of a DVD is $18, then it is put on sale for $14. Which integer represents the change in the price?
Responses
A -14-14
B -4-4
C 44
D 14
To find the change in price, we subtract the sale price from the regular price:
$18 - $14 = $4.
Therefore, the change in price is $4.
Hence, the correct answer is B) -4.
A rock climber starts at an elevation 630 feet above sea level and descends to a point 180 feet lower than his starting point. What is the rock climber's elevation?
Responses
A 450 feet450 feet
B 810 feet810 feet
C −810 feet−810 feet
D −450 feet
To calculate the rock climber's elevation, we subtract the descent of 180 feet from the starting elevation of 630 feet:
630 feet - 180 feet = 450 feet.
Therefore, the rock climber's elevation is 450 feet.
Hence, the correct answer is A) 450 feet.
The temperature started at 35°F. If the temperature went down 4°F and then up 2°F, whats is the temperature difference relative to the high temperature?
Responses
A -2°F-2°F
B -1°F-1°F
C 1°F1°F
D 2°F
To calculate the temperature difference relative to the high temperature, we add the change of 2°F to the starting temperature of 35°F:
35°F - 4°F + 2°F = 33°F.
Therefore, the temperature difference relative to the high temperature is 2°F.
Hence, the correct answer is D) 2°F.
