Answer:
<h2>
150 ft tall</h2>
Step-by-step explanation:
first, lets first convert 2ft 6in to ft:
since ft=12 in, 6=0.5 ft
thus, the height of the birdbath is 2+0.5 ft=2.5ft
now, lets convert 18 inch shadow to ft:
since ft=12 in, 18=1.5 ft
now, we can use the following proportions to solve this problem:
2.5/1.5=x/90
1.5x=90*2.5
1.5x=225
x=225/1.5
x=150
Thus, the oak tree in the garden is 150 ft tall
-4x+y=1
Answer is:
y=4x-1
——————
-2x+y=1
Answer is:
y=2x+1
Answer: I don't know i'm taking a benchmark about that question an that pop up
Step-by-step explanation:
The answer is "D".
x+x+(x+11)+(x+11)=86
4x+22=86
subtract 22
4x=64
divide by 4
x=16
