Answer:

4/5 is the slope

Step-by-step explanation:

The line is written in the form

A stalk of corn casts a shadow of 117 inches, while a 8-inch ear of corn casts a shadow of 13 inches. Use similar triangles to f

Gemiola [76]

Answer: 72

We can use ratios

117 inches / 13 inches = 9

The corn cast shadow is 9 times bigger than the example we are given.

9 * 8 = 72

How many solutions can be found for the equation 5x + 3(x − 1) = 10x − x − 5? (4 points)

Svet_ta [14]

Answer:

The correct option is b.

Step-by-step explanation:

To find the number of solutions, we need to solve the equation:

$5x + 3(x - 1) = 10x - x - 5$

Let's group all the "x" on the equation.

$5x + 3x - 10x + x = 3 - 5$

Now, let's solve for "x".

$-x = -2$

$x = 2$

Therefore, the equation has one solution. The correct option is b.

I hope it helps you!

In an arithmetic sequence {an}, if a1 = 5 and d = 3, find a72. A) 216 B) 218 C) 221 D) 223

Phoenix [80]

The arithmetic sequence with the given condition is determined recursively by

$\begin{cases}a_1=5\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}$

So we have

$a_2=a_1+3$

$a_3=a_2+3=a_1+3(2)$

$a_4=a_3+3=a_1+3(3)$

and so on with the general pattern

$a_n=a_1+3(n-1)$

This means the 72nd term in the sequence is

$a_{72}=a_1+3(72-1)=5+3(71)=218$

so the answer is B.
