Answer:
see below
Step-by-step explanation:
The symbol ≤ means the dot at -9 will be solid, because the value -9 is part of the solution set. The line is shaded for values less than -9, because that is what the inequality is telling you are values of r that are in the solution set.

Answer:
(b) 13.5
Step-by-step explanation:
The upper vertex would be ...
3/2(3, 3) = (4.5, 4.5)
and the right vertex would be ...
3/2(4, 0) = (6, 0).
The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...
A = (1/2)bh
A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle
Jess rounds a number, x to one decimal place
The result is 9.8
Write down the error interval for X
Answers
The error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.
The number that is rounded off is:
x = 9.8
9.8 can be rounded off for 9.75 to 9.84
So, this means that:
9.75 ≤ x
or 9.84 ≥ x
So, the error interval becomes:
9.75 ≤ x ≤ 9.84
Therefore, we get that, the error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.

Find the missing terms 14.5_,_,18.4
Answers
The 4th term is a + 3d = 18.4
We know what a is so we can substitute it into the above equation...
14.5 + 3d = 18.4
3d = 3.9
d = 1.3
So the common difference is 1.3... now you just have to add that to the first term so...
14.5 + 1.3 = 15.8 (2nd term)
15.8 + 1.3 = 17.1 (3rd term)

we have rectangle that has the side, 8 and 15
P(r)=2(8)+2(15)=16+30=46
we also have half of the circle with the diameter =8 and r=4
Circumference =2*3.14*r
C=2*3.14*4=25.12
we need just half of the circle 25.12/2=12.56
P figure=46+12.56=58.56
Area= rectangle=l*w=8*15=120
Area(circle)=3.14*r^2=3.14*16=50.24

An airplane descends 1.5 miles to an elevation of 6.05.Find the elevation of the plane befor its descent the intial elevation of the plane was blank miles
Answers
Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles
