Answer:
The coordinates of the science lab is:
x = -14/3 , y = 1
Step-by-step explanation:
∵ P is (-8 , -1) and Q is (2 , 5)
∵ The point of the science lab is (x , y)
∵ The science lab point divided PQ at ratio 2 : 1 from Q (two thirds PQ)
∴
∴
∴
∴
∴ The point of science lab = (-14/3 , 1)
Answer:
0.0875 km²
Step-by-step explanation:
1km = 1000m
1km²=1000*1000=1000000m²
6500m²=6500/1000000 km²
= 0.0065 km²
total area= 0.0065+0.08=0.0875 km²
Answer: None of the above
Step-by-step explanation:
Answer:
s ≤ 60 - (3 ÷ 1/15)
Step-by-step explanation:
Minimum of blankets to crochet = 3
She has 60 days to crochet
She crochet at a rate of 1/15 of a blanket per day
Therefore to crochet 1 blanket
Number of days needed =x
1 blanket = rate per day * x days
1 = 1/15 * x
1 = 1/15x
Divide both sides by 1/15
x = 1 ÷ 1/15
= 1 × 15/1
= 1×15
x = 15
15 days needed to crochet 1 blanket
To crochet 3 blanket = 15 days × 3 blanket
=45 days needed.
Darcie can skip = 60 days - 45 days
= 15 days
The inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.
s ≤ 60 - (3 ÷ 1/15)
Solving the inequality
s ≤ 60 - (3 ÷ 1/15)
s ≤ 60 - (3×15/1)
s ≤ 60 - 45
s ≤ 15
Answer:
B
Step-by-step explanation:
You're trying to isolate the m so add 16 to both sides to cancel the -16
