Answer:

50 degrees

Step-by-step explanation:

You know it's a right angle, so that means it is 90 degrees, just subtract 40 degrees from 90 since you know a = 40 and a+b=90

Answer:

90 (degrees) - a = b

90 (degrees) - (40) = 50 (degrees)

Step-by-step explanation:

The little box in the corner indicates that it is a right angle, all right angles are equal to 90 degrees.

They gave you the value of (a) and we know that (b) must be equal to 90 degrees when added to (a).

Subtract 90 from 40 and that gives you fifty degrees.

The Ivring Berlin Learning Center would like a possible net profit of $650,000 on its new resource manual it sells to schools. T
vazorg [7]

Answer:

Selling price should be $21 per unit.

Step-by-step explanation:

Cost price of manual = Fixed price + variable cost per package×Number of units sold

= 780000+19.85×1250000 = $25592500

Now we know Learning center wants a profit = $650000

Then profit = sale price - cost price

650000=sale price - 25592500

Sale price = 650000+25592500 = $26242500

This is the sale price of 1250000 units then selling price per unit should be = Total selling price/Number of units sold

= $26242500/1250000 =20.994 or $21

Selling price should be $21 per unit.

PLZ HELP ME what is the value of y^-5 / x^-3 for x=2 and y =-4 a)-1/128 b)10/3 c) -128 d) 128
Tomtit [17]
1st, substitute <em>x</em> and <em>y</em> with 2 and -4, which'd be \frac{-4^{-5}}{2^{-3}}.
Then, simplify, to get -\frac{1}{128}.
This would be -0.0078125 in <em>decimal</em> form, or - 1/128 in <em>fraction</em> form.

Hope this helps! ^^
