I think she can use it 8 times
Answer:
Adam
Step-by-step explanation:
Speed is calculated with the formula distance over time.
Convert all measurements to the same unit: ft/s.
<u>Speed of Frank:</u>
d/t
=11/s
<u>Speed of Emily:</u>
d/t
=86/10
=8.6/s
<u>Speed of Adam: </u>
There are 5280 feet in a mile.
d/t
=5280/388
=13.6/s
<u>Speed of Noah:</u>
There are 60 seconds in a minute.
d/t
=600/60
=10/s
Adam runs the fastest because 13.6 > 11 > 10 > 8.6.
Third angle = 180 - (6x+7) - (10x-3)
= 180 - 6x - 7 - 10x + 3
= 176 - 16x
just minus the sum of triangle by the 2 angles and you're left with the 3rd one
Answer:
Step-by-step explanation:
<u>Given information</u>
f(x) = 3x² + x - 3
g(x) = 5x
<u>Given expression</u>
f(x) g(x)
<u>Substitute values into the given expression</u>
(3x² + x - 2) (5x)
<u>Expand the parenthesis by distributive property</u>
3x² · 5x + x · 5x - 2 · 5x
(3 · 5) (x² · x) + 5 (x · x) - (2 · 5) x
Hope this helps!! :)

Answer:
1 6/11
Step-by-step explanation:
10/4 + 1/3. 30/12 + 4/12 =34/22 = 17/11 = 1 6/11. 10/4 ×3/3 =30/12. 1/4 × 4/4 =4/12. 34/22 ÷2/2 = 17/11 = 1 6/11
