Answer: The minimum number of chaperones need for the trip is 10.

Hope this helps!

Step-by-step explanation:

171 students divided by the amount of students per two adults

171/9 = 19 since there is two adults 19/2= 9.5 but since you can't have 9 and a half adults better to round it up to 10.

Please help me guys!!! Value of X?
Arturiano [62]
The value of X is 56.66°. The sine of X (opposite/hypotenuse) is 66mm/79mm. When finding angle measurements, you would use sin−1 instead of sin, which is used for finding side lengths. So, X= sin−1(66/79). This then results to 56.66° after using the trig functions in a calculator.

Help me with this please everyone
cupoosta [38]
First, let's simplify each expression by combining like terms:

A: 9x-3x-4 = 6x-4

B: 12x-4 = 12x-4 (Already Combined terms)

C: 5x+x-4 = 6x-4

When looking at the list of equations, it is clear that only Expression A and C are equivalent. Brianna failed to combine like terms and plug in more points than 0. 

I Hope this Helps!

What is the area of a triangle with vertices at (−4, 1) , ​ (−7, 5) ​ , and ​ (0, 1) ​ ?
Mekhanik [1.2K]
Plot the points on a graph. Connect the dots into a triangle. See that the height of the triangle is from y=5 down to y=1. So the height is 4 units.
 Area of a triangle: A = (1/2)BH

You need to find the length of the base. Which is from point (-4,1) to (0,1). You can use the distance formula r just see from the graph that the base is 4 units.

A = (1/2)(4)(4)
A = 8

** Distance formula fyi
d² = (X-x)² + (Y-y)²
with points (X,Y) and (x,y)
