Answer:
6 seconds
Step-by-step explanation:
Initial distance of Mario from motion detector = 2 ft
Speed of Mario = 1.5 ft/sec
Total distance of Mario from motion detector = 11 ft
Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft
Given that:
Distance = 9 ft
Speed = 1.5 ft/sec
Formula:
[tex]Distance = Speed \times Time[/tex]
[tex]\Rightarrow 9 =1.5 \times Time\\\Rightarrow Time = \dfrac{9}{1.5}\\\Rightarrow Time = \bold{6\ sec}[/tex]
So, at 6 seconds, Mario will be 11 ft from the motion detector.

Nicole is making smoothies. She uses 1.2 kilograms of apples and 600 grams of strawberries. How many kilograms of fruit does Ann use in all?
Answer:
wait Ann? wasn't the question stating that Nicole was making smoothies? kinda threw me off
either way: 1.8 kilograms of fruit
Step-by-step explanation:
first you need to convert all of your measurements into a same unit, so 600 grams into kilograms, remember that 1 gram = 0.001 kilograms, so all you need to do is multiply 600 by 0.001
you'll get 0.6 and then you add that to 1.2 kilograms which is 1.8 in total. hope it helped

A 3 ft tree casts a 10 ft. shadow. How many feet long is the shadow of a 26 ft tall tree at the same time? If necessary, round to the nearest tenth.
Answer:
8 feet
Step-by-step explanation:
It is given that, a 3 ft tree casts a 10 ft. shadow. It means that 1 ft long shadow will cast by [tex]\dfrac{3}{10}[/tex] feet long tree.
Let 26 ft tall tree will cast x feet long shadow. To find it using unitary method we get :
[tex]x=\dfrac{3}{10}\times 26\\\\x=7.8\ \text{feet}[/tex]
or
x = 8 feet
So, 8 feet long is the shadow of a 26 feet tall tree.

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y = eight divided by x squared + 2
Answer:
f(x)= [tex]\frac{8}{x} +2[/tex]
g(x)=x[tex]^{2}[/tex]
Step-by-step explanation:
f(g(x) ) =[tex]\frac{8}{g(x)} +2>>>> f(g(x) ) = \frac{8}{x^{2} } +2[/tex]
