Answer:5 times more
Step-by-step explanation:
9.1 x 5 is 45.5
0.1 x 5 = 0.5
9.0 x 5= 45.0
0.5 + 45.0 = 45.5
Solve for x: 2 over 5 (x - 4) = 2x

Answer:
84
Step-by-step explanation:
Total students he surveyed: 27
Amount that found it something OTHER than easy: 14 (11 moderate + 3 difficult)
This means that found it something other than easy
Multiply that by 162 to find the proportion for the larger population:
162 * (14/27), and we get 84.
Answer:
A and B: slope = 0
S and T: slope = undefined
Step-by-step explanation:
To find the slope of the line that passes between a pair of points, use the slope formula, . Substitute the x and y values of two points into that formula and simplify.
1) Let's try this with the first problem. Substitute the x and y values of (4,5) and (-3,5) into the formula, then solve:
So, the slope of the line between A and B is 0.
2) Do the same with the second problem, substituting the x and y values of (3,-6) and (3,-9):
However, we can't divide by zero. So, the slope between points S and T must be undefined.
Answer:
C
Step-by-step explanation:
the area (A) of the hexagon can be calculated as
A = pa ( p is the perimeter and a the apothem )
p = 6 × 10 = 60 and a = 5 , then
A = × 60 × 5
= 30 × 5
= 150
≈ 259.8 cm² ( to the nearest tenth )
