Answer:
Step-by-step explanation:
4.
a)
P = 2width + 2length
8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length
length = 3x
b)
sides= 1/4 of 3x = 3x/4
perimeter of square = 4* side = 4*3x/4 = 3x
c)
x= 4
P rectangle =8x= 8*4= 32
P square = 3x = 3*4 = 12
32-12 = 20 cm greater is the P rectangle than P of square
d)
A rectangle = 2x*x = 2*4*4 = 32
A square =(3x/4)² = (3*4/4)² = 9
32-9 = 23 cm² greater is the A rectangle than A of square
5.
4Comic+1 Nonfiction
4comic = 8y so 1 comic = 2y
1 nonfiction = (3+7y)+ 2y
a)
1 nonfiction = 7y+2y+3 = 9y+3
b)
total= 8y+9y+3 = 17y+3
if y=4
total = 17*4 +3 = $71
Answer:
Step-by-step explanation:
3y=7x+2
one pair is (1,3)
go on adding 3 in x=1,you get corresponding value of y.
x=4,y=10,(4,10)
and so on .
Answer:
DGF=226
Step-by-step explanation:
Angle 113 is a inscribed angle since two it is on the exterior of the circle. We can find the central angle by multiply 2 by 113.
113×2=226
Since the central angle measure 226, that means the arc DGF measures 226 degrees.
DGF=113
Answer:
The 40% marked up price of refrigerator is $1260.
Step-by-step explanation:
The cost price of the refrigerator = $900
Now, the mark up should be 40%
Calculating the markup on the cost price , we get
40 % of $900 = 
or, 40 % mark up = $360
Now, the Marked up cost = Cost Price + Marked up Price
= $900 + $360 = $1260
Hence, the 40% marked up price of refrigerator is $1260.
