Answer:
10.2 m
Step-by-step explanation:
180 - 81 - 30 = 69
law of sines
x /sin 30 = 19/sin 69
x = 10.2
Answer:
1.75...?
Step-by-step explanation:
Uhh... Well if you're that desperate I'll try it.
If the actual football diameter is 21
Plug it into 1 : 12
x : 21
x / 21 = 1 / 12
12x = 21
x = 7 / 4
I don't really understand what the problem's asking though so this is probably wrong.
Answer:
h = 2
Step-by-step explanation:
I'm assuming your periods are multiplication signs.
(h + h) X (h X h) = 16
When adding two variables like the first set of parentheses, it would become 2h. When multiplying two like variables, you add the exponents. h is the same as writing h¹. So h¹ x h¹ gives you the answer of h².
So now your equation would look like:
2h X h² = 16
As above, when you multiply two like variables you would add the exponents. Also if any number are in front of the variable you would multiply those numbers. So you have 2h¹ x 1h² and that would be 2h³. If it had been
2h¹ x 2h², your answer would have been 4h³.
But so far you have 2h¹ x 1h² = 16
2h³ = 16
Dividing both sides by 2 you get
h³ = 8
To find h you have to take the cubed root of 8. What number multiplied by itself 3 times gives you 8? 2 x 2 x 2 = 8 2 x 2 = 4 and x 2 = 8.
h = 2
If you put this into the original equation you have:
(2 + 2) x ( 2 x 2) = 16
( 4 ) x ( 4 ) = 16

Answer:
i cant see the choices but i think this is khan academy
Step-by-step explanation:
A.
By using distributive property you can figure out all the answers.
A: 4*3a, 4*2= 12a + 8
B: 4*3a, 4*8= 12a + 32
C: 6*6a, 6*2= 36a + 12
D: 6*6a, 6*8= 36a + 48
