Answer:

1/2x = 4 1/2

Where x = Number of servings = 9 servings

Step-by-step explanation:

Mini made a recipe that yields 4 and 1 over 2 cups.

1 recipe = 4 1/2 cups

1 serving = 1/2 cups

1/2 cups = 1 servings

4 1/2 cups = x servings

Cross Multiply

1/2 × x = 4 1/2

x = 4 1/2 ÷ 1/2

x = 9/2 ÷ 1/2

x = 9/2 × 2

x = 9 servings.

Therefore, the expression tha will help Mini to determine the number of servings her recipe will yield is

1/2x = 4 1/2

Where x = Number of servings = 9 servings

Answer:

\huge\boxed{A.\ -\dfrac{9}{4}+2i}

Step-by-step explanation:

The standard form of a complex number:

z=a+bi\\\\a,\ b\in\mathbb{R}

3i+\left(\dfrac{3}{4}+2i\right)-(3+3i)=3i+\dfrac{3}{4}+2i-3-3i\\\\=\left(\dfrac{3}{4}-3\right)+(3+2-3)i=-2\dfrac{1}{4}+2i=-\dfrac{9}{4}+2i

Kids bought a package with 2 9/ 16 lb of ground meat to make hamburgers he was he has 2/5 pound of ground meat left about how ma
poizon [28]

Answer:

The quantity of ground meat he use for hamburgers is                                   2 \frac{13}{80} pounds

Step-by-step explanation:

Given as :

The total quantity of ground meat bought to make hamburgers = 2 \frac{9}{16}

Or, The total quantity of ground meat bought to make hamburgers = \frac{41}{16} pound

The quantity of ground meat left after use = \frac{2}{5} pound

Now, let The quantity of ground meat used for hamburgers = x pound

So, x = The total quantity of ground meat bought - The quantity of ground meat left

Or, x = \frac{41}{16} pound -  \frac{2}{5} pound

Or, x =  \frac{205-32}{80} pound

I.e x = \frac{173}{80}

∴  x = 2 \frac{13}{80} pounds

Hence The quantity of ground meat he use for hamburgers is                        2 \frac{13}{80} pounds  . Answer

At a rate of 36 miles per hour, it takes Henry 15 minutes to drive from the library to his house. Show how to find the distance
EastWind [94]
This is applying the formula
distance=rate*time

We have a slight problem, though, because we are measuring rate in miles per hour, and we are measuring time in minutes. To make this problem solvable, we need to convert to either miles per minute or convert the time to hours. I'm going to convert the 15 minutes into hours:
15min*\frac{1 hour}{60 min}=\frac{1}{4}hour

Now that all of the units match, we have:
distance=36\frac{mi}{hr}*\frac{1}{4}hr

You can finish from there I'm sure.
