Answer:
17
Step-by-step explanation:
y=4(3)+5
y=12+5
y=17
Let’s choose the first one, and do the proportions.
x/30 = 90/100
Cross multiply and you have
100x = (30)(90)
100x = 2700
x = 27
And the fourth one: multiply by the decimal equivalent of the percent.
90% = 90/100 = 0.9
0.9 x 30 = 27
You chose these because your “online tutor” finds them easiest to explain XD
Answer:
9 + f = 16
Step-by-step explanation:
So just say 9 + f = 16 since the tree grew to 16, and the f is the amount.
Answer:
a) y-2=1/2(x-6) b) The y-intercept of this line is -1.
Step-by-step explanation:
y-y1=m(x-x1)
y-2=1/2(x-6)
------------------
y=1/2x-6/2+2
y=1/2x-3+2
y=1/2x-1
y=mx+b where m=slope and b=y-intercept.

Answer: 658.3</h3>
==================================================
Explanation:
The adjacent complementary angle to that 28 degree angle is 62 degrees because 62+28 = 90.
If the reference angle is the upper acute angle 62 degrees, then the y is the opposite leg and the side 350 is the adjacent leg.
Use the tangent ratio
tan(angle) = opposite/adjacent
tan(62) = y/350
350*tan(62) = y
y = 350*tan(62)
y = 658.254262871217
y = 658.3
