Its 130°
Heheheheh because 25+25=50
180-50=130
Answer:
the answer is in the highlighted box
Step-by-step explanation:
Percent means parts out of 100
120%=120/100=1.2
80%=80/100=0.8
'of' means multiply
1.2 times a=0.8 times b
a=12
1.2 times 12=0.8 times b
14.4=0.8 times b
divide both sides by 0.8
18=b
so
a=12
b=18
a+b=12+18=30
Answer:
width = 47
Length = 100
Step-by-step explanation:
The perimeter of the rectangle has the formula
P = 2(L + W)
P = 2L + 2W
Length = 6 yards longer than double it's width.
Mathematically,
length = 6 + 2W
We put this into the formula for perimeter
P = 2(6+2W)+2W
294 = 12+4W+2W
294 = 12+6W
Collect like terms
294-12 = 6W
282 = 6w
Divide through by 6
W = 282/6
W = 47
This is the width
Remember length = 6 + 2(W)
So
Length = 6+2(47)
= 6+94
= 100
Width = 47
L = 100
These are the dimensions
1st round table has a center located ate (-4,6)
radius is 4 feet and each unit is equal to one foot.
edge of the round table will land at (-8,6)
an additional 5 feet must be added to give space for the guests to walk between tables.
edge of the 2nd table to the left of the 1st table, (-13,6)
to get the center of the 2nd round table, add 4 feet: distance (-17,6)
The center of the table found immediately to the left of the 1st table is (-17,6)
