Answer:

D.) 4 1/20

Step-by-step explanation:

2 1/4 * 9/5

Change 2 1/4 to an improper fraction

4*2+1 = 9/4

9/4 * 9/5

Multiply straight across the numerators and then straight across the denominators

9 * 9 = 81 4 * 5 = 20

81/20

Change this back into a mixed number

81 divided by 20 = 4 1/20

your car broke down and the final bill was $306.50. The part that was replaced cost $119 and the charge mechanics labor was 75 p

erastova [34]

Answer:

$\huge\boxed\text{Equation:}$ $\huge\boxed{\text{Equation: }119+75x=306.50}\\$

$\huge\boxed{\text{Hours worked on: } 2.5}$

Step-by-step explanation:

We can create an equation for this problem by converting the words to an equation.

The <em>flat fee</em> was $119. We then add $75 for every hour worked. This means that this becomes $119+75x$ . Since the total cost was $306.50, the equation is $119+75x=306.50$ .

We can now solve for x, the amount of hours worked, to find it’s value.

$119 + 75x = 306.5\\\\75x=187.5\\\\x = 2.5$

Hope this helped!

Natasha_Volkova [10]

Step-by-step explanation:

Given:

Wavelength of wave : 3.3m

Frequency of wave : 100Hz.

speed/velocity : ?

As we know

velocity = wavelength × Frequency

= 3.3 × 100

=330ms−1

So the speed of the wave is 330 ms·¹
