Answer:
False
Step-by-step explanation:
It's been a while since I did this but here we go:
So to find if the triangle lengths are possible, we take the shorter two lengths and we add them.
Those shorter two lengths sum have to be <em>greater</em> than the longest length.
I hope this helps.
B=blue
g=green
r=red
2 times as many blue as green
b=2g
3 times as many red as blue
r=3b
subsitute 2g for b
r=3(2g)=6g
r=6g
r+g+b=765
so we subsitute
r=6g
g=g
b=2g
6g+g+2g=765
add like terms
9g=765
divide both sides by 9
g=85
subsitute
b=2b
b=2(85)
b=170
170 blue
Answer:
8.6 × 10-4
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer. Therefore, the decimal number 0.00086 written in scientific notation is 8.6 × 10-4 and it has 2 significant figures.
Answer:
Jeremy's house is 4.5 inches far from his friend's house on the map
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The house of Jeremy's friend is 72 miles away from his home
∴ The actual distance between the two houses is 72 miles
∵ The scale on Jeremy's map is 
inch is equivalent to 8 miles
∴ Each miles on the map represents actual distance 8 miles
By using the ratio method
→ Map length : Actual length
→ inch : miles
→ : 8
→ x : 72
By using cross multiplication
∵ x × 8 = × 72
∴ 8 x = 36
- Divide both sides by 8
∴ x = 4.5
x represent the distance between the two houses on the map
Jeremy's house is 4.5 inches far from his friend's house on the map
