The value of x in the triangle is 0.21
<h3>How to determine the value of x?</h3>
The given parameters are:
mA = 90°
cos(B) = 7x - 0.55
sin (C) = x + 0.71
Since the angle is a right triangle, then
C + B = 90
In a right triangle;
If C + B = 90, then
sin(C) = cos(B)
So, we have:
7x - 0.55 = x + 0.71
Evaluate the like terms
6x = 1.26
Divide both sides by 6
x = 0.21
Hence, the value of x in the triangle is 0.21

Answer:
1. The median.
Step-by-step explanation:
First arrange in ascending order:
5.8 6.1 6.1 6.2 6.2 6.2 6.3 6.8 6.8 7
The median = 6.2. On the box plot the median is marked at 6.3 so that is incorrect. All the others are correct
Answer:
adults : 0 children: 600
Step-by-step explanation:
x + y = 600
6x+4y = 2400
4×(x + y = 600) = 4x+4y = 2400
(6x+4y = 2400) - (4x+4y = 2400) = x=0
so y=600
Giả sử cho A1 = {1,2,3,4}, A2 = {1,2,7,12}, A3={0,1,2,4,8,16,32} và A4 = {-3,-2,-1,0,1,2,3}

Maria had 2 yards of trim when she started.
Step-by-step explanation:
Step 1:
All of the sides of the triangle is 22 inches long each.
The total length of the sides of the triangle
So the total length of the trim for the banner is 66 inches long.
If Maria still has a foot of trim left, she had 6 inches of the trim left.
The length of the trim when she started inches.
Step 2:
Now we need to convert the 72 inches into yards.
We have 1 inch = 0.0277778 yards.
So 72 inches
So Maria had 2 yards of trim when she started.
