3-(s+4)
less than- subtract
sum- addition
since it said 3 less than the sum of a number and 4 that means you would have to add s and 4
Answer:
<em>$</em><em>420</em>
Step-by-step explanation:
<em>Principal</em><em> </em><em>=</em><em> </em><em>$</em><em>7000</em>
<em>Rate</em><em> </em><em>=</em><em> </em><em>8</em><em>%</em>
<em>Time</em><em> </em><em>=</em><em> </em><em>9</em><em> </em><em>months</em>
<em>9</em><em> </em><em>months</em><em> </em><em>=</em><em> </em><em>3</em><em>/</em><em>4</em><em> </em><em>or</em><em> </em><em>0.75</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>year</em>
<em>Simple</em><em> </em><em>Interest</em><em> </em><em>=</em><em> </em><em>Principal</em><em> </em><em>*</em><em> </em><em>Rate</em><em> </em><em>*</em><em> </em><em>Time</em><em> </em><em>÷</em><em> </em><em>100</em>
<em>=</em><em> </em><em>$</em><em>7000</em><em> </em><em>*</em><em> </em><em>8</em><em>%</em><em> </em><em>*</em><em> </em><em>0.75</em><em> </em><em>÷</em><em> </em><em>100</em>
<em>=</em><em> </em><em>$</em><em>420</em>

Remember when you learning about the "Least Common
Multiple" and you wondered when in the world you would
ever need to use it ?
Well, here you are ! Hello !
The next time they will cross the starting line together is the
LCM (Least Common Multiple) of 30 and 40 .
Do you remember how to find it ?
Here's one easy way:
Count by 30s until you come to a number that's divisible by 40 .
Laura's first lap. . . . . . . . 30 seconds . . . not divisible by 40
Laura's two laps . . . . . . . 60 seconds . . . not divisible by 40
Laura's three laps. . . . . . 90 seconds . . . not divisible by 40
Laura's four laps. . . . . . 120 seconds . . . divisible by 40
After 120 seconds, Laura has completed four laps,
Shelby has completed only three laps.
Step-by-step explanation:
So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.
So we set up the equation
cos θ = adj/hype
cos θ = 5/8
θ = ![cos^{-1} (5/8)](https://tex.z-dn.net/?f=cos%5E%7B-1%7D%20%285%2F8%29)
θ=51.3178125...
θ=51°
