Answer:
d = 5,35 ft
Step-by-step explanation: See annex
Figure in annex is clear,
sin ∠42⁰ = d / 8
And
sin ∠42⁰ = 0.669
d/8 = 0,669
d = 0,669*8
d = 5,35 ft
Answer:
3,000 words
Step-by-step explanation:
we know that
Emilio cay type 850 words in 17 minutes
Remember that

so
using proportion
Find out how many words can Emilio type in 60 minutes (one hour)
Let
x ---> the number of words

3 + 4x = 2y - 9
2y = 4x + 3 + 9
2y = 4x + 12
y = 2x + 6
if it's parallel, than if y = ax + b, a = 2 and you need to find b
(4, -4)
x = 4
y = -4
-4 = 2*4 + b
-4 = 8 + b
b = -12
so an equation is:
y = 2x - 12
Answer:
3 spoons and 6 forks
Step-by-step explanation:
9 = x + y; x= 9-y
44 = 4x + 6y
44 = 4(9-y) + 6y
44 = 36 - 4y +6y
44 = 36 +2y
2y = 44-36 = 12
y = 12/2 =6
x= 9-y = 9-6 =3
