Clayton is at most 2 meters above sea level. Using C for Clayton, which inequality correctly represents this statement?
Nataly [62]

Answer:

C ≤ 2

Step-by-step explanation:

Given that :

Clayton is at most 2 meters above sea level ;

Let Clayton = C

Clayton's distance can be represented by the inequality :

2 meters above sea level is positive, +2

At most 2 meters above sea level means, Clayton could be anywhere between + 2 metwrs but not more than 2 meters

Hence, Clayton's distance can be represented by the inequality :

C ≤ 2

The sum of Sally and Beth's age is 60. Six years ago, Sally was 3 times as old as Beth. What are their present ages?
andrew-mc [135]
It's quite simple. Look:

Lets let S- be the age of Sally and B- can be the age of Beth

S+B=60
S-6=3(B-6)

S-6=3B-18
S=3B-18+6
S=3B-12

3B-12+B=60
4B=60+12
4B=72
B=72/4
B=18

B=60-18
B=42

The ages are (B)18 and (S)42

Hope this helps!! :)

An arrow is shot vertically upward at a rate of 280 feet per second. Use the projectile formula
vfiekz [6]

Time is 16.75 seconds when the arrow reaches 200 ft

Step-by-step explanation:

  • Step 1: Find time at height of 200 ft

Height = 200 ft

v = 280 ft/s

Projectile formula, h = -16t² + vt

⇒ 200 = -16t² + 280t

⇒ 16t² - 280t + 200 = 0

⇒ 2t² - 35t + 25 = 0 (dividing by common factor 8)

Using quadratic formula to find t

t = (35 ±√35² - 4×2×25)/2×2

t = (35 ±√1225 - 200)4 = 35 ± 32.02/4

∴ t = 67/4 or 3/4  

t = 16.75 seconds
