Answer:

option d

d ---- sin30 =5/x

Answer:

D. sin 30° = 5/x

Step-by-step explanation:

recall that for a right triange, considering one of the acute angles θ

sin θ = length of opposite side / length of hypotenuse

from the picture, we can see that

θ = 30°, length of opposite site = 5 and length of hypotenuse = x

substituting this into the above equation

sin 30° = 5/x

Answers

y = 3x - 1

The format for slope intercept form is:

y = mx + b

m represents the slope and that was given so:

y = 3x + b

Now we have to substitute the value from the given point into “y” and “x” to solve for “b”

(2) = 3(1) + b
2 = 3 + b
-1 = b

Now that we know b we can substitute it into y = 3x + b to get the equation of the line

y = 3x - 1

Step-by-step explanation:

Henry is hanging flyers on front doors for his father's pizza business. He hung 130 flyers in 95 minutes. He still has 870 flyers to hang. His brothers, Nick and Adam, come to help. Nick hangs flyers 50% faster than Henry, and Adam hangs flyers 20% slower than Henry. Find the constant of proportionality for the flyer hanging rate of Henry, Nick, and Adam combined? (round to nearest tenth)

Answers

Given:
Henry: 130 flyers in 95 minutes.
Nick hangs flyers 50% faster than Henry
Adam hangs flyers 20% slower than Henry
Remaining flyers: 870

Henry's rate per minute = 130/95 = 1.37 flyers per minute

Nick: 1.37 * 1.50 = 2.055 or 2.06 flyers per minute
Adam: 1.37 * 0.80 = 1.095 or 1.10 flyers per minute

1.37 flyers + 2.06 flyers + 1.10 flyers = 4.53 flyers per minute.

870 flyers ÷ 4.53 flyers per minute = 192 minutes

the constant proportionality for the flyer hanging of all three is 4.53 flyers per minute. They will finish hanging the remaining 870 flyer within 192 minutes.

the answer is 4.53 but you have to round to the nearest tenth so you get 4.5

For the following geometric sequence find the recursive formula: {-1, 3, -9, ...}.

Answers

Based on these first few terms, we can deduce that the next term is computed by switching the sign of the previous one, and multiplying it by 3: we start with -1, we switch the sign (1) and multiply by 3 (3); then again we switch the sign (-3) and multiply by 3 (-9), and so on.

Since switching sign is the same as multiplying by -1, we can compute every next term by multiplying the previous one by -3:

$a_1 = -1\na_2 = a_1\cdot(-3) = (-1)\cdot(-3)=3\na_3 =a_2\cdot(-3)=3\cdot(-3)=-9$

So, the recursive formula is

$a_n = -3a_(n-1)$

because it states precisely that the next term is -3 times the previous one.

It takes one and a half minutes to swim a length. How many length can I swim in 12 minutes

Answers

I think the answer is 8 because it is like a ratio.
1.5 : 1
12 : ?
so 12/1.5= 8 so to get to 12 you multiply 1.5 by 8 and you would do the same thing to the other part of the ratio, and 1*8 is 8. Hope this helped.
