Answer:
120 miles
Step-by-step explanation:
Let d represent the number of miles driven on the first day. Then 1.5 times d came to 180 miles. Dividing both sides of this equation by 1.5 to isolate d, we get:
180 miles
--------------- = 120 miles
1.5
Thefamily drove 120 miles during the first day of their trip.
According to the question requirements
v= 4/3*pi*r^3
dv/dt = 4*pi*r^2*dr/dt
when
d= 1.7
r= 0.85
and
dv/dt = 2
2= 4*pi*(0.85)^2*dr/dtthus the the speed of increasing of the balloon's diameter is
dr/dt = 1/(2pi*(0.85)^2)

Answer:
16x <= 80
It's D
16x= 16$ for each hat
80= the most he can spend
In context: Each hat cost 16$ and the most he can spend is 80, nothing more than that.
Answer:
1.y = -5/3 = -1.667
2. y = -3/2 = -1.500
Step-by-step explanation:
90 + -1 = -91
-45 + -2 = -47
-30 + -3 = -33
-18 + -5 = -23
-15 + -6 = -21
-10 + -9 = -19
-9 + -10 = -19
-6 + -15 = -21
-5 + -18 = -23
-3 + -30 = -33
-2 + -45 = -47
-1 + -90 = -91
1 + 90 = 91
2 + 45 = 47
3 + 30 = 33
5 + 18 = 23
6 + 15 = 21
9 + 10 = 19
