Answer:

5 x 9 = 45

Step-by-step explanation:

A good way to estimate this would be rounding to the nearest whole number.

First we'll look at 4.73. If we're rounding to the nearest whole number, then that means we'll look at the digit one place to the right of 4. The digit to the right of 4 is 7. 7 is greater than 5 so we round up. We get 5. If we do the same for the other number we see that it also gets rounded up to 9. So our new equation is: 5 x 9. That is a simple multiplication equation and when we multiply we get 45.

Hope this helped!

Answer:

Matias divided 7.6 by 10 raised to the power of -2.

Step-by-step explanation:

Given : Matias preformed an operation with 7.6 and a number. He ended up moving the decimal point in 7.6 two places to the left.

To find : Matias divided 7.6 by 10 raised to the power of ?

Solution :

Matias preformed an operation with 7.6 and a number.

He ended up moving the decimal point in 7.6 two places to the left we have to multiply it with 0.01

i.e. $7.6\times 0.01=\frac{7.6}{100}=0.076$

So, Matias divided 7.6 by 10 raised to the power of -2.

The cost see for manufacturing X units of a certain product is given by C equals X squared -10 X +35 find the number of units ma

Marianna [84]

Answer:

110 units

Step-by-step explanation:

Fill in the given value and solve for x.

c = x^2 -10x +35

11035 = x^2 -10x +35

11025 = x^2 -10x +25 = (x -5)^2 . . . . subtract 10 to complete the square

x = 5 +√11025 = 5 +105 . . . . find the positive solution

x = 110

The number of units manufactured at a cost of 11,035 is 110 units.
