Answer:
[tex]\dfrac{1}{64}[/tex]
Step-by-step explanation:
[tex](-32)^{-1.2} = \dfrac{1}{(-32)^{\frac{6}{5}}} = \dfrac{1}{(\sqrt[5]{-32})^6}} = \dfrac{1}{(-2)^{6}} = \dfrac{1}{64}[/tex]

A bus drives for 3 1/2 hours at an average speed of 56mph.
How far does the bus drive?
Answer:
196 km
Step-by-step explanation:
Distance = speed x time
So to work it out, it would be 3.5 x 56
= 196km
Answer:
A bus drives for 3 1/2 hours at an average speed of 56mph.
To Find :
How far does the bus drive?
Step-by-step explanation:
Times of journey(T)=3 1/2 =7/2hours
Average speed of bus(v)=56mph
We know the formula:
Average speed (v)=total distance (d)/Time(T)
So:
Total distance (d)=qverage speed(v)×time(t)
Total distance (d)=56×7/2
Total distance(d)=28×7=196 miles
It means distance travel by bus is 196 miles.

Becky is using the expression 2z + 3 to represent the number of chairs in her classroom. There are twice as many chairs as tables, and there are three extra chairs in the back. What does z represent?
The number of chairs.
The number of tables.
The number of chairs at tables.
The number of chairs and tables.
Answer:
The number of chairs
Step-by-step explanation:
The equation is 2z + 3
2 ( = multiply by)
z ( # of chairs)
+3 ( the 3 extra chairs in the back)
Answer:
The number of tables
Step-by-step explanation:
Sens there is twice as many chairs as tables, the number 2 represents the chairs. The 3 represents the 3 extra chairs in the back. so the only logical object to represent z is the number of tables.

the nearest tenth.
Answer:
P=23.4
Step-by-step explanation:
so using the pytogoren theroum
c2-b2= a2
so a= 6.9
so P= 6.9+6.8+9.7=23.4

Montana is known for having very chilly winters. One night, the temperature was falling by 2 degrees Fahrenheit each hour. At sunset, the temperature was -5 degrees Fahrenheit. How many hours will it take for the temperature to reach -19° F?
Answer:
7 hours
Step-by-step explanation:
We are given that
At sunset, the temperature=-5 degrees Fahrenheit
Each hour, temperature falling=2degrees Fahrenheit
We have to find time taken to reach the temperature -19° F.
Let x be the time time taken to reach the temperature -19° F
According to question
[tex]-5+x(-2)=-19[/tex]
Where we taking 2 negative because temperature decreases.
[tex]-5-2x=-19[/tex]
[tex]-5+19=2x[/tex]
[tex]14=2x[/tex]
[tex]x=\frac{14}{2}[/tex]
[tex]x=7[/tex]
Hence, it will take 7 hours for the temperature to reach -19° F.

Answer:
Area = 113.01 m²
Step-by-step explanation:
From the picture attached,
Area of the quadrilateral ABCD = Area of triangle ABC+ Area of triangle ACD
Construction to be done → Draw a perpendicular from a point A to the opposite side CD
Area of Δ ABC = [tex]\frac{1}{2}(AB)(BC)[/tex]
= [tex]\frac{1}{2}(12)(10)[/tex]
= 60 m²
Area of triangle ACD = [tex]\frac{1}{2}(AE)(CD)[/tex]
From ΔAEC,
sin(29°) = [tex]\frac{AE}{AC}[/tex]
AC = [tex]\sqrt{(12)^2+(10)^2}[/tex] [By Pythagoras theorem]
AC = [tex]\sqrt{244}[/tex]
AC = 15.62 m
Therefore, AE = 15.62sin(29)
= 7.57 m
Area of ΔACD = [tex]\frac{1}{2}(7.57)(14)[/tex]
= 53.01 m²
Area of ABCD = 60 + 53.01
= 113.01 m²

If these two shapes are similar, what is the measure of the missing length b?
Answer:
B = 7mm
Step-by-step explanation:
This is probably an enlargement problem.
To solve this:
the blue triangle has all of it's measurements you need. Let's start with that.
6/36 =
We know that one side, the bottom side of the green triangle is 42mm.
6/36 = b/42
We could simplify 6/36 into 1/6
1/6 = b/42
AHA! the denominators are easy! 6 times 7 is equal to 42, so 1 times 7 should equal b!
1/6 = 7/42
Check:
6/36 = b/42
36b = 6*42
36b = 252
b = 252/36
b = 7
So yes! B is 7 mm. Pls mark me brainliest, as I never have a single brainliest.
