Answer:
r = -14
Step-by-step explanation:
3 = r + 17
r + 17 = 3
r + 17 - 17 = 3 - 17
r = -14
Assuming that the base is 5 cm and the height is 12 cm, so
by dilating the legs by a scale factor of 2/3, the new dimensions are:
base = 5 cm * (2 / 3) = 10/3 cm
height = 12 cm * (2 / 3) = 8 cm
So the area of a right triangle is calculated using the
formula:
A = b h / 2
A = (10/3) * 8 / 2
<span>A = 13.33 cm^2</span>
Answer:
He'll need 288 cups to make a waffle on his 24 foot diameter circular griddle.
Step-by-step explanation:
In order to find out how much batter Danny needs we first need to compute the area of the first pans, since it is a circular pan their area is given by A = 2*pi*r. So we have:
Area of the first pan = 2*pi*(6/2) = 18.84 square inches
Area of the second pan = 2*pi*(24/2) = 75.36 square foots
We now need to convert these values to be in the same unit, we'll convert from square foots to square inches:
Area of the second pan = 75.36 * (12)^2 = 10851.84 square inches
We can now use a proportion knowing that the batter and the thickness of the waffles are the same. If 0.5 cup of flour can make a waffle on 18.84 square inches then x cup of flour can make a waffle on 10851.85 square inches. Writing this in a mathematical form, we have:
0.5/x = 18.84/10851.84
18.84x = 0.5*10851.85
x = 10851.85*0.5/18.84 =288 cups
Answer:
m= 1/2 or y= 1/2x - 2
