Step-by-step explanation:

Use the sine and cosine trig functions

21) cos(52)=13/x

x=13/cos(52)

x=21.1

22) sin(75)=6/x

x=6/sin(75)

x=6.2

Gennadij [26K]
M=slope=(y2-y1)/(x2-x1)=(-6-1)/(8-8)=-7/0 which is technically undefined.  This is just a vertical line namely:

x=8  (you can think of a vertical line as having infinite slope)

9 Peter walked 8,900 feet from home to school.
kow [346]

\bf \begin{array}{ccll} miles&feet\\ \cline{1-2} 1&5280\\ x&8900 \end{array}\implies \cfrac{1}{x}=\cfrac{5280}{8900}\implies 8900=5280x \\\\\\ \cfrac{8900}{5280}=x\implies 1.6856\approx x\implies \stackrel{\textit{rounded up}}{1.7=x}

Answer:

Let x rep the lenght of the shorter one

Then the longer one is 2x+1

Therefore

(2x+1) + x = 16

We now solve for x

2x + 1 + x = 16

Group and evaluate like terms

3x +1 = 16

3x = 16 -1

× = 15/3

x = 5

So the shorter one is 5 ft

The longer one is 2(5)+1= 11

Given number = 2n + 4,
=> 2n = twice a number, n represents the unknown number
=> + = add or more than
=> 4 = four
So, this can be say as = twice a number more than 4 , or four more than twice a number.
Thus, the given equation’s answer is letter B. four more than twice a number
=> Four = 4
=> more than = +
=> twice a number = 2n
=> 4 + 2n, the same as 2n + 4</span>
