I say C because 1/2 is only half the day so multiply 4/5 by 2 to get 8/5

I think that it’s A) 2/5. I just multiplied the fractions with each other.

What other angle between O and 360 degrees has the same TAN value as 71

atroni [7]

Answer:

-289 degrees

Step-by-step explanation:

You are looking for what is called Coterminal Angles.

To find a coterminal angle between 0 and 360 you add or subtract 360.

In this case, we subtracted 360 from 71
71 - 360 = -289
tan(-289) = 2.90
If TAN 71 = 2.90 and TAN -289 = 2.90, you know -289 is your answer.

Write an equation in slope-intercept form of the line with the given characteristics:

kobusy [5.1K]

Answer:

1. y = -3x + 5

2. y = 1/4x - 2

Step-by-step explanation:

y=mx+b

1. 5 = -3(0) + b, so b = 5

y = -3x + 5

2. (-2-(-1))/(0-4) = -1/-4 = 1/4

-2 = 1/4(0) + b, so b = -2

y = 1/4x - 2

A salesman used three types of order forms: A, B, C. He used 40 of Form A. Of Form B he used four times as many as Form A plus 1

mixas84 [53]

Answer:

The correct option is A. 440

Step-by-step explanation:

Let a, b and c represents the number of orders from forms A, B and C,

According to the question,

$a = 40$ ,

$b = 4a + \frac{1}{2}c$

$c = a + \frac{1}{2}c$

From these equations we get,

$b = 160 + \frac{1}{2}c----(1)$

$c = 40 + \frac{1}{2}b---(2)$

Substitute the value of b from (1) to (2),

$c = 40 + \frac{1}{2}(160 + \frac{1}{2}c)$

$c = 40 + 80 + \frac{1}{4}c$

$c-\frac{1}{4}c = 120$

$\frac{4c-c}{4}=120$

$\frac{3c}{4}=120$

$c=\frac{480}{3}=160$

From (1),

$b = 160 + \frac{1}{2}(160)=160 + 80 = 240$

$\because a + b + c = 40 + 240 + 160 = 440$

Hence, he used 440 forms total,

i.e. OPTION A is correct.
