anthony bought an 8 foot board.He cut off 3/4 of the board to build a shelf,and gave 1/3 of the rest to his brother for an art p
e-lub [12.9K]
Convert your feet to inches.
So 8 times by 12 = 96 inches
if you have 3/4 of the board used. 
3/4= .75 
if you were to times 96 by .75 = 72 inches.
So you used 72 inches and you have 24 inches left

now do 1/3= .33
times .33 by 24= 8
8 inches is how long you would give to Anthony's brother.

Given the line with equation 7 − 2 = 8,
timurjin [86]

Hey there!!

The basic slope-intercept formula :

y = mx+ b where ' m ' is the slope and ' b ' is the slope-intercept.

Given equation : 7x - 2y = 8

We will have to isolate the ' y '

... 7x - 2y = 8

Subtract 7x on both sides

... -2y = -7x + 8

Divide by - 2 on both sides

... y = ( 7x / 2 ) - 4

Hence,

slope = 7/2 = 3.5

y-intercept = ( 0 , -4 )

Hope it helps!!

19. A spherical balloon has a circumference of 19cm. what is the approximate surface area of the balloon to the nearest square c
Tamiku [17]
The main formula of a spherical surface area is SA= 4 x Pi x r²
the circumference is C= 19cm =2 Pi r, so r = C/ 2Pi = 19 / 6.28 =3.02cm
so the surface area can be found by computing
SA= 4x 3.14x 3.02² =114.5, the nearest square centimeter is <span>A) 114 cm^2</span>
