Answer:
D. 105 ft²
Step-by-step explanation:
The total surface area is the sum of the base area and the triangular face areas.
Area of base:
A = s²
A = (7 ft)² = 49 ft²
Area of 4 triangles:
A = 4(1/2)bh
A = 2(7 ft)(4 ft) = 56 ft²
Total surface area:
base area + triangle area = 49 ft² +56 ft² = 105 ft²
Answer:
Second graph
Step-by-step explanation:
The second graph is the correct one. Why? because the y intercept is (0, 3), and also because the base, 1/5, is between 0 and 1, which leads to a decaying exponential graph.
Answer:
The width W is :
![W=\frac{3}{5}](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B3%7D%7B5%7D)
Step-by-step explanation:
<em>Let A be the area of the rectangle </em>
<em>Let L be the length of the rectangle</em>
<em>Let W be the width of the rectangle </em>
______
Formula:
A = L × W
__________
![\begin{aligned}A &=L \times W \\\Rightarrow W &=\frac{A}{L} \\\Rightarrow W &=\frac{\frac{3}{8}}{\frac{5}{8}} \\&=\frac{3}{8} \times \frac{8}{5} \\&=\frac{3 \times 8}{8 \times 5} \\&=\frac{3}{5}\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7DA%20%26%3DL%20%5Ctimes%20W%20%5C%5C%5CRightarrow%20W%20%26%3D%5Cfrac%7BA%7D%7BL%7D%20%5C%5C%5CRightarrow%20W%20%26%3D%5Cfrac%7B%5Cfrac%7B3%7D%7B8%7D%7D%7B%5Cfrac%7B5%7D%7B8%7D%7D%20%5C%5C%26%3D%5Cfrac%7B3%7D%7B8%7D%20%5Ctimes%20%5Cfrac%7B8%7D%7B5%7D%20%5C%5C%26%3D%5Cfrac%7B3%20%5Ctimes%208%7D%7B8%20%5Ctimes%205%7D%20%5C%5C%26%3D%5Cfrac%7B3%7D%7B5%7D%5Cend%7Baligned%7D)
Im pretty sure that she has 12 cups.
Answer:
2(4x^2+1)
Step-by-step explanation:
The greatest common factor of 8x^2 and 2 is 2.
We can factor:
2(4x^2+1)
How did we get the expression in the parentheses?
It is just 8x^2 divided by 2 and 2 divided by 2
Hope this helps!
