Answer:
-2.1
Step-by-step explanation:
2.5(x+4)=4.75
or,2.5x+10=4.75
or,2.5x=4.75-10
or,2.5x= -5.25
or,x =-5.25/2.5
or,x= -2.1
∴x=-2.1
(Ans)

Answer:
5.0 
Step-by-step explanation:
The volume of a rectangular prism is given as:
V = L * W * H
where L = length
W = width
H = height
Put all the dimensions in the same unit, metre (m).
Length = 5 m
Width = 40 cm = 40 / 100 = 0.4 m
Height = 2500 mm = 2500/1000 = 2.5 m
The volume of the prism is:
V = 5 * 0.4 * 2.5 = 5.0 
590000
The 1000 place is 1 which is less than 5 so it gets rounded down
Answer:
22 ft^2
Step-by-step explanation:
The area of a table with diameter 6 ft
A = pi r^2 = pi (6/2) ^2 = pi 3^2 = 9pi
The area of a table with diameter 8 ft
A = pi r^2 = pi (8/2) ^2 = pi 4^2 = 16pi
Subtract 16pi-9pi = 7pi
Using 3.14 for pi
7 * 3.14
21.98 ft^2
To the nearest square foot
22 ft^2
Answer:
The sum of the interior angle measures of a triangle
is 180°. You can find the sum of the interior angle
measures of any n-gon, where n represents the
number of sides of the polygon, by multiplying
(n - 2) 180°. In a polygon, an exterior angle forms a
linear pair with its adjacent interior angle, so the
sum of their measures is 180°. In a triangle, the
measure of an exterior angle is equal to the sum of
the measures of its two remote interior angles.
