The answer is left two places.
For example 5.% would be 0.05 as a decimal.
Answer:
![Area = 2,031ft^2](https://tex.z-dn.net/?f=%20Area%20%3D%202%2C031ft%5E2%20)
Total weight of gravel on the roof = ![24,372 pounds](https://tex.z-dn.net/?f=%2024%2C372%20pounds%20)
Step-by-step Explanation:
The area Adams planned to cover with gravel can be divided into 3 rectangles as shown in the diagram attached.
We would have 3 rectangles. See the attachment below to check out how we arrive at the dimensions of the 3 rectangles.
Area of rectangle = L*W
Area to be covered by gravel = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
Area to be covered with gravel = ![(30*17) + (13*9) + (52*27)](https://tex.z-dn.net/?f=%20%2830%2A17%29%20%2B%20%2813%2A9%29%20%2B%20%2852%2A27%29%20)
![Area = (30*17) + (13*9) + (52*27) = 2,031ft^2](https://tex.z-dn.net/?f=%20Area%20%3D%20%2830%2A17%29%20%2B%20%2813%2A9%29%20%2B%20%2852%2A27%29%20%3D%202%2C031ft%5E2%20)
Total weight of gravel on the roof = 12 pounds per square foot multiplied by total area of the roof to be covered = ![12 * 2031 = 24,372 pounds](https://tex.z-dn.net/?f=%2012%20%2A%202031%20%3D%2024%2C372%20pounds%20)
Answer:
length = 12 cm
Breadth = 4 cm
Step-by-step explanation:
Let length = l
breadth = ![\frac{1}{3}l](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dl)
Area of rectangle = 48 sq.cm
length * breadth = 48
![l * \frac{1}{3}l = 48\\](https://tex.z-dn.net/?f=l%20%2A%20%5Cfrac%7B1%7D%7B3%7Dl%20%3D%2048%5C%5C)
![\frac{1}{3}l^{2}=48\\\\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dl%5E%7B2%7D%3D48%5C%5C%5C%5C)
![l^{2}=48*3\\\\l^{2}=144\\\\ l = \sqrt{144}\\\\](https://tex.z-dn.net/?f=l%5E%7B2%7D%3D48%2A3%5C%5C%5C%5Cl%5E%7B2%7D%3D144%5C%5C%5C%5C%20%20%20l%20%3D%20%5Csqrt%7B144%7D%5C%5C%5C%5C)
l = 12 cm
breadth = ![\frac{1}{3}l = \frac{1}{3}*12 = 4 cm](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dl%20%3D%20%5Cfrac%7B1%7D%7B3%7D%2A12%20%3D%204%20cm)
length = 12 cm
Breadth = 4 cm
Answer:
y = 4![(2)^{x}](https://tex.z-dn.net/?f=%282%29%5E%7Bx%7D)
Step-by-step explanation:
An exponential function in standard form is
y = a ![b^{x}](https://tex.z-dn.net/?f=b%5E%7Bx%7D)
Use ordered pairs from the table to find a and b
Using (0, 4), then
4 = a
( note that
= 1 ), so
a = 4, then
y = 4 ![b^{x}](https://tex.z-dn.net/?f=b%5E%7Bx%7D)
Using (1, 8)
8 = 4
= 4b ( divide both sides by 4 )
b = 2
y = 4
← represents the values in the table
