find area of 1 small bubble
πr² = π × 5²
= 78.54
total area of 4 small bubble
78.54 × 4 = 314.16
total area of 4 small bubble = area of big bubble
= 314.16
find it's radius
πr² = 314.16
r² = 314.16 ÷ π
r² = 100
r = √100
r = 10
Answer:
8/10,3/4, -3/4,-7/10
Step-by-step explanation:
From greatest to least, they -7/10 and -3/4 is a negative so thats the least because its below zero. 8/10 and 3/4 is positive so thats a decimal. The greatest is 8/10 because if you divide it, it give you .8 and 3/4 is .75. .8 is greater because it refers to 80 and .80 is greater that .75
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
