Answer:
Step-by-step explanation:
<2 + <1 + 20 = 180 A straight line has 180 degrees.
<2 is given as 90 degrees.
90 + <1 + 20 = 180 Combine like terms
<1 + 110 = 180 Subtract 110 from both sides
<1 = 180 - 110
<1 = 70
<1 + <2 + <3 = 180
<1 = 70
<2 = 90
70 + 90 + <3 = 180
160 + <3 = 180 Subtract 160 from both sides
<3 = 180 - 160
<3 = 20
20 + 20 + <4 = 180 Straight line theorem stated above.
40 + <4 = 180 Subtract 40 from both sides
<4 = 180 - 40
<4 = 140
Answer:
R(p) = -4p^2 + 300p when p=20.
R(p) = -4(20)^2 + 300(20)
R(p) = -1600 + 6000
R(p) = 4400
The mass when p=20 years is 4400.
Answer:
x=3,0
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
x
=
3
,
0
It would be B. because if you put the numbers on a number line, you notice that -14 is further down than -3 since -3 is closer to 0, so -14 is less than -3
