Answer:
The tree is 14 ft. tall.
Step-by-step explanation:
If Ryan is 6 ft. tall and his shadow is 12 ft. tall than his shadow is twice his size. So if the trees shadow is 28 ft. tall then you would divide. Here is the equation:
28 ÷ 2 = 14
To check our work you would do 14 * 2 = 28.
Hope this helps!!
Answer:
Step-by-step explanation:
the answer is D
I'm assuming that you meant to write 'two 100-w per hour light bulbs used a total of 400w. how many hours did the bulbs run'
so each used 100w per hour and there are 2 light bulbs so in 1 hour 200w is used
200wh times x hour=200wx=400w
divide both sides by 200w
x=2
they ran for 2 hours
Answer:
y = -8
Step-by-step explanation:
When y = -2/5, the slope is 0.
Seeing this, we can make the equation the same as the y-value of the point given.
Hence,
y = -8

This is the rule for any calculation of this type. Note that you can replace X(B) by X(A) and the same for Y because the answers are squared and you'll always get the same value
