When this 3 digit number is rounded to the nearest hundred it rounds to 900.The digit in the ones place is the fifth odd number
gizmo_the_mogwai [7]

Answer:

949

Step-by-step explanation:

If the 3 digit number is rounded to 900, then this number is between 900 and 950.

The digit in the ones place is the fifth odd number begginning with 1, so this number is number 9.

Lastly, the sum of digits is 22.

Putting our number as 9x9, where x is the tens digit, we know that 9 + x + 9 = 22, so we have that x = 4

So, our number is 949

I need help finding the angles. The answer Isn't even
mart [117]

The 3 inside angles of a triangle equal 180.

Add the 3 angles together to equal 180:


X + (5x-20) + 4x = 180

Simplify the left side by adding like terms:

10x-20 = 180

Add 20 to each side:

10x = 200

Divide both sides by 10:

x = 20


Angle A = x = 20

Angle B = 4X = 4(20) = 80

Angle C = 5x-20 = 5(20) -20 = 100-20 = 80

A printer has a contract to print 100,000 posters for a political candidate. He can run the posters by using any number of plate
yulyashka [42]

Answer:

25

Step-by-step explanation:

From the given information;

Numbers of posters that can be printed in an hour = no of impression/hour × no of plate utilized in each impression.

= 1000x

Thus, the required number of hours it will take can be computed as:

\implies \dfrac{100000}{1000x} \\ \\ =\dfrac{100}{x}

cost per hour = 125

If each plate costs $20 to make, then the total number of plate will equal to 40x

∴

The total cost can be computed as:

C(x) = (\dfrac{100}{x}) \times 125 + 20 x --- (1)

C'(x) = (-\dfrac{12500}{x^2})  + 20  --- (2)

At C'(x) = 0

\dfrac{12500}{x^2} = 20

\dfrac{12500}{20} = x^2

x^2= 625

x = \sqrt{625}

x = 25

C'' (x) = -12500 \times \dfrac{-2}{x^3} +0

C'' (x) = \dfrac{25000}{x^3}

where; x = 25

C'' (x) = \dfrac{25000}{25^3}

C''(x) = 1.6

Thus, at x = 25, C'' > 0

As such, to minimize the cost, the printer needs to make 25 metal plates.
