Let us assume that Timmy and Jared are eating 2 cupcakes combined. As it is not given if they are eating 2 each.
Time taken by Timmy and Jared to eat 2 cupcakes = 3 minutes
Time taken by both of them to eat 18 cupcakes in =
=27
Hence, Timmy and Jared can eat 18 cupcakes in 27 minutes.
Answer:
B
Step-by-step explanation:
The level of the river is 34 feet, so that is the constant. It drops at a rate of .5 feet per day. This means that the water level is getting lower, so we would be subtracting in this case.
Answer: from 10 to 15
Step-by-step explanation: Toby didn’t run as much in those five minutes, compared to his other times.
Answer:
x = 31.12
Step-by-step explanation:
First find the base (hypotenuse) of the smaller triangle (the isosceles triangle): Its three sides are 11, 11 and b. b can be found using the Pythagorean Theorem: b^2 = 11^2 + 11^2 = 242. Then b = √242, or b = approximately 15.56.
b (which is approximately 15.56) is the shorter leg of the large (right) triangle. The trig function needed to solve for x is the cosine:
adjacent side
cos 60 degrees = ----------------------
hypotenuse,
15.56
which becomes (1/2) = ------------
x
Solving this for x, we get: x = 2(15.56) = 31.12
