Answer:
6.0.
Step-by-step explanation:
The line marked 20 is 2 times the line marked 3x - 8 (because the last line cuts the 2 sides of the large triangle in 2).
2(3x - 8) = 20
6x - 16 = 20
6x = 36
x = 6.0.
Answer:
76
Step-by-step explanation:
Use .25 to represent the 1/4 of a mile.
Since it is a given radius around the boulder, we would treat it as such and find the area of the circle around the boulder.
To do this, you do .25² * 3.14
.0625 * 3.14 = .19625
15/.19625 = 76 and some change, but you need to round down to 76
Answer is 76.
19 is you awnser since:
By order of operations first do the exponent and then do the multiplication and finally the subtraction
3 to the third is 27
4 times 2 is 8
so 27-8 is 19
3 to the(3)-(4)(2)
27-(4)(2)
27-8
19 is your answer
