Max has two cats. Rex and Roman. If Rex weighs 11 7/18 pounds and Roman weighs 11.329 pounds, which cat weighs the most?

Vinvika [58]

Answer: Rex weighs more.

Step-by-step explanation:

You have to change both of the numbers into the same form. I did decimal form.

Rex - 11 7/18 = 11.389 (rounded to the hundredths)

Roman - 11.329

Rex is bigger.

Tan(a)+cot(b) simplify please.

Hitman42 [59]

Answer:

tan a + cot b

Step-by-step explanation:

It's already simplified.

There are alternate forms like

$sec(a)csc(b)cos(a-b)\\\\sec(a)csc(b)[sin(a)sin(b)+cos(a)cos(b)]\\\\\frac{sin (a)}{cos (a)} +\frac{cos(b)}{sin(b)}$

John is standing in his backyard and decides to estimate the height of a tree. He stands so that the tip of his shadow coincides

Andrew [12]

The tree is 820 inches tall using the similarity of triangles.

To get the height of the tree, we will use the properties of similar triangles expressed as:

$\frac{70in}{7ft} = \frac{h}{75ft+7ft}\\\frac{70in}{7ft} = \frac{h}{82ft}\\$

Note that 1 foot = 12inches

7ft = 84in and 82ft = 984in

h is the required height of the tree. Simplify the equation above to get the height "h" and replace feet with inches;

$\frac{70}{84} = \frac{h}{984}\\84h =70 \times 984\\84h = 68,880\\h=\frac{68,880}{84}\\h= 820in$

Hence the tree is 820 inches tall using the similarity of triangles.
