Answer:
5/2<x<5
Step-by-step explanation:
-7<3-2x<-2
or -7-3<-2x<-2-3
or -10<-2x<-5
or -10/-2>x>-5/-2
or 5>x>5/2
or 5/2<x<5
Therefore, 5/2<x<5 is the solution.
<span>In the question "This figure shows the procedure for constructing a" The correct answer is "bisector of an angle" (option C).
To construct an angle bisector: Draw an arc that is centered at the vertex of the angle to intersect both sides of the angle. From the point of intersection of the previous arc and the both sides of the angle, draw two more arcs to intersect at a point. The radius for the two arcs must be equal. Then draw a straight line from the point of intersection of the later set of arcs and the vertex of the angle.</span>
Answer:
9, 13, 17
Step-by-step explanation:
The difference between the greatest value and the least is 8, the range.
Add the three numbers to total 39, then divide by 3 to get the mean, 13.
Answer:
The answer is 390 × pi.
Step-by-step explanation:
Big cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 9^2 x 15
= 1272.3 cubic inches
Small cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 3^2 x 5
= 47.1 cubic inches
1272.3 - 47.1 = 1225.2 cubic inches
1272/3.14 ≈ 390
The answer is 390 × pi.
Answer: (pi) (6 squared)
Step-by-step explanation:
Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:
Area of a circle: (pi) radius^2
The diameter (d) of a circle is equal to: 2 radius
So:
D = 2r
Replacing with the value given:
12 =2r
12/2=r
radius= 6 inches
Back with the Area formula:
A = (pi) 6^2
