3,680 sq. in.
(36*20)*4= 2880
(20*20)*2= 800
7.95 ÷ 1.06 = $7.50
This works as by dividing 7.95 by the percentage multiplier 1.06 it will give you the original amount.
An alternative method is to find out what 100% (7.95) is, then divide by 10 to find 10% and then divide by 10 again to find 1% and then multiply the 1% by 6 and subtracting the answer from 7.95.
Since 10 is a positive the opposite must be negative. Opposite integer of 10 is -10 ( negative 10).
Happy studying ^-^
Answer:
my day is going good just got on the school
Answer:
x = 61
Step-by-step explanation:
Left hand triangle containing 1 angle of 74
Label the other angle opposite the marked side also as 74
Find the third angle. Call it y.
y + 74 + 74 = 180 Combine like terms
y + 148 = 180 Subtract 148 from both sides.
y = 180 - 148
y = 32
=============
Now work with the triangle on the right.
label the angle making up the right angle = z
32 + z = 90 These two angles are complementary = 90
32 - 32 + z = 90 - 32 Subtract 32 from both sides
z = 58 Use 58 wherever you see z
x + x + z = 180 Substitute
2x + 58 = 180 Subtract 58 from both sides
2x = 122 Divide by 2
x = 61
