Answer:
Jack is evil.
Step-by-step explanation:
Jack wasn't very smart, one-day jack made a science experiment to increase the temperature of frogs 2 fold every week starting from 2 degrees Celcius, the graph shows how much he cooked the poor frog in the weeks that sadly, followed.
(in case you don't know fold just means multiplied by that much so 20k$ going 10 fold is 200k$)
Answer:
10 square2
36 + 64 = 100. In other words, 6² + 8² = 10²
Answer:
1 =30 km
1/3=7,5 km
5=150
Im not sure tho but should be fine
Answer:
She can be a member for 8 months
Step-by-step explanation:
Let x be the number of months
30 + 10.5(x) = 114
30 + 10.5x = 114
10.5x = 114-30
10.5x = 84
x = 84/10.5
x = 8 mints
Answer:
4 mph
Step-by-step explanation:
Let's say m is the speed of the motor boat, and r is the speed of the river.
20 minutes is 1/3 hour, and 30 minutes is 1/2 hour.
Distance = rate × time
8 = (m + r) × 1/3
8 = (m − r) × 1/2
We want to find the value of r. Let's start by solving for m in one equation, then substitute into the other.
8 = (m − r) × 1/2
16 = m − r
m = r + 16
8 = (m + r) × 1/3
8 = (r + 16 + r) × 1/3
8 = (2r + 16) × 1/3
24 = 2r + 16
8 = 2r
r = 4
The speed of the river's current is 4 miles per hour.
