1. You have to make a system of equations.
2. The problem gives the following information:
- <span>. Emi said wow I think the top of that waterfall is about 20 ft more than three times the height of a young Redwood.
- Margaret had a different opinion she said no I think it's about 50 ft less than 4 times the height of the Redwood.
3. So, you have:
y: the height of the waterfall.
x: </span>the height of the Redwood
4. The equations are:
y=3x+20 (i)
y=4x-50 (ii)
3x+20=4x-50
x=70 ft
y=3x+20
y=230 ft
H<span>ow tall is the Redwood and how high is the waterfall?
</span>
The Redwood: 70 ft
The waterfall: 230 ft
(3t² +t -12t - 4)(t+2)=0
(3t³ - 5t² -26t -8) =0
t = -2
Answer:
CD=7
Step-by-step explanation:
BAC angle=CED angle (alternate angles are equal)
therfore;
CB=CD(equal angle opposite sides are equal)
80% of 25
percent means parts out of 100
'of' means multiply
80% of 25 means
80/100 times 25=40/50 times 25=20/25 times 25=20
answer is 20 problems
