Mathematics

Answer:

35° (I may be wrong)

Step-by-step explanation:

An isosceles triangle has an interior angle sum of 180° (like all triangles).

So...

180°-40°= 140°

And because we know that isoceles triangles and two congruent sides, we just have to divide 140° by 2.

140°÷2=70°

But the picture says 2h and h is a side so...

70°÷2=35°

4. Builtrite D is considering the purchase of a new machine for $500,000 which would require a $5000 installation charge. Employ
Paraphin [41]

Answer:

Builtrite D should purchase the machine

Step-by-step explanation:

Cash outflow in year zero = $ 500,000 + $ 25,000 ( training cost ) + $ 30,000 ( Net working capital)

Cash outflow in year zero = $ 555,000

Terminal cash flow in year 10  = $ 150,000 + $ 30,000 ( NWC)

Terminal cash flow in year 10  = $ 180,000

Operating cash flow per year = [ Savings - expenses - depreciation ] X ( 1 - tax rate) + depreciation

Net present value = -500,000 + \frac{116,000}{1.15^1} + \frac{116,000}{1.15^2} +...+ \frac{180,000}{1.15^{10}}

The Net present value of purchasing the machine = $32,071.42

Builtrite D should purchase the machine

Solve the formula for the specified variable.<br><br> V=AQT for A
Nitella [24]

Answer:

A = \frac{V}{QT}

Step-by-step explanation:

To solve the problem you want to have A on one side, everything else on the other side. You can move over the variables by divind them from each side as shown:

AQT = V

AQT = \frac{V}{1}

AQ = \frac{V}{T}

A = \frac{V}{QT}
