equilateral triangle is a triangle with all three sides equal
isosceles triangle is a triangle with two sides of the same length
scalene triangle is a triangle in which no 2 sides have equal lengths
equiangular triangle is a triangle in which all angles are equal
triangle is the union of three segments determined by 3 noncolinear points
BEST estimate of this amount is 
. Correct option A. 2 x 10^7 .
<u>Step-by-step explanation:</u>
Here we have , Hoover Dam spans the Colorado River on the Nevada-Arizona state line. For its construction, the federal government purchased 21,670,000 pounds of gates and valves. We need to find BEST estimate of this amount . Let's find out:
21,670,000 pounds
⇒ 21,670,000 pounds
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Now, Rounding of 2.167 we get 2 ,So
⇒
Hence , BEST estimate of this amount is . Correct option A. 2 x 10^7 .
It's C i took the test......
Answer:
Step-by-step explanation:
A.)
Let the equal number of hours be represented by variable h;
The two equations will be as follows;
Jack; 40 +30h
Mark; 50 +25h
Next, equate them;
40 + 30h= 50 + 25h
30h - 25h = 50 - 40
5h = 10
h =10/5
h = 2
Therefore, they charge the same amount at 2 hrs.
B.) The amount charged;
Replace the variable H in any of the two equations above with 2 to solve for the amount.
Equation 40+30h = 40 + (30*2)
=40 + 60
= $100
Answer:
D. 0.65
Step-by-step explanation:
0.05 x 5=0.25
0.01 x 5=0.05
0.07 x 5=0.35
0.25+0.05+0.35=0.65
the all must pay 0.65 each
