If d - 10. r<br> PLZ HELP ASAP I ONLY HAVE A MIN

Can somebody please help me with this math question

LekaFEV [45]

Answer:

107

Step-by-step explanation:

Since we know that the triangles have the same 3 sides, they are congruent (SSS). We also know that a triangle's angles add up to 180 degrees.

We first need to add 41 and 32 to give us the number we need to subtract from 180.

41+32=73

Now we need to subtract from 180 degrees.

180-73=107

If 107 is the measure of angle D, then according to SSS congruence it is also the measure of angle B.

1.) You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into t

rjkz [21]

Here we have 3 general algebraic problems that we need to solve. Using simple reasoning we can solve these.

1) You will buy a board of length L.

You will cut two pieces that are 1.4 ft long.

So at this point, the length of the board piece is:

L - 1.4ft - 1.4ft = L - 2.8ft.

Now, you want this to be 1.17 times longer than 1.4ft, then we need to solve:

L - 2.8ft. = 1.17*(1.4ft) = 1.638ft

L = 1.638ft + 2.8ft = 4.438ft

Rounding to the nearest tenth, we get:

L = 4.4 ft

This is the length of board you should buy.

2) Here we know:

You pay $0.13 per KW-h

This month, you pay a total of $83.96

The total number of KW-h you used is equal to the quotient between the total amount you paid and the price of a single KW-h, this is:

N = $83.96/$0.13 = 645.85

This month you used 645.85 KW-h in your home.

3) Here we know:

You pay $0.09 per KW-h.

Running the bulb for one hour consumes 0.06 KW-h

So, if you leave one of these lights on all day (24 hours) it would consume:

24*0.06 KW-h = 1.44 KW-h

If you instead leave 5 of these bulbs, you will consume 5 times that amount:

5*1.44 KW-h = 7.2 KW-h

This is in one single day, if you do this for 30 days, the total consumption is:

30* 7.2 KW-h = 216 KW-h

And you pay $0.09 for each one of these, then the cost is 216 times $0.09

Cost = 216*$0.09 = $19.44

The Pear company sells pPhones. The cost to manufacture x pPhones is C ( x ) = - 21 x² + 67000 x + 20006 dollars (this includes

pishuonlain [190]

Answer:

Company should produce 8000 phones for the maximum profit.

Step-by-step explanation:

Function representing cost to the manufacturer is,

C(x) = -21x²+ 67000x + 20006

Function that represents the revenue generated is,

R(x) = -28x² + 179000x

Function representing profit to the company,

Profit = Revenue generated - Cost price

= -28x² + 179000x - (- 21x² + 67000x + 20006)

= -28x² + 21x² + 179000x - 67000x - 20006

P(x) = -7x² + 112000x - 20006

Since this function is a quadratic function therefore, the maximum price generated will be for

$x=-\frac{b}{2a}$

From the given quadratic function, a = (-7), b = 112000 and c = -20006

Therefore, for $x=-\frac{112000}{2\times (-7)}$

Or x = 8000 the profit to the company will be maximum.

That means pear company should produce 8000 phones for the maximum profit.
