55/6.21 = x/1....55 mins to 6.21 miles = x min to 1 mile
cross multiply
6.21x = 55
x = 55/6.21
x = 8.86 minutes
Answer:
B, D
Step-by-step explanation:
Any inequality that does not include the "or equal to" case will be graphed with a dashed line.
<h3>Application</h3>
The "or equal to" case is included when the inequality symbol is one of ≤ or ≥. When symbols > or < are used, the boundary line of the solution space is dashed (or the end point on the number line is an open circle).
The inequalities that will be graphed with a dashed line are ...
- 2x -4y < 12 . . . . choice B
- x +7 > -1 . . . . . . .choice D
Method 1:
You can use the formula of an area of equilateral triangle:

a - length of side
We have a = 10 yd. Substitute:

Method 2:
Use the Pythagorean theorem (look at he picture).

<em>subtract 25 from both sides</em>

The formula of an area of a trinagle:

b - base
h - height
We have b = 10 yd and h = 5√3 yd. Substitute:

The answer is a bar graph probably.<span />
