Answer:

$y = \frac{18 - 3x}{ - 6}$

Step-by-step explanation:

Given,

$3x - 6y = 18$

$- 6y = 18 - 3x$

$y = \frac{18 - 3x}{ - 6}$

This how we can solve for y.

23. Stacie is a resident at the medical facility where you work. You are asked to chart the amount of solid food that she consum

lesya692 [45]

Answer:

4.42 ounces

Step-by-step explanation:

Given:

The solid food Stacie has eaten in the noon meal:

1. $\frac{1}2$ of a 3-ounce serving of meatloaf.

2. $\frac{3}4$ of her 3-ounce serving of mashed potatoes

3. $\frac{1}3$ of a 2-ounce serving of green beans

To find:

How many ounces of solid food was consumed by Stacie (upto 2 decimal places) ?

Solution:

Let us convert the given fractions to decimal form upto 2 decimal places:

1. $\frac{1}{2}\ of\ 3\ ounces$ $= \frac{1}{2}\times 3 =1.50\ ounces$ meatloaf .

2. $\frac{3}{4}\ of\ 3\ ounces$ $= \frac{3}{4}\times 3 =2.25\ ounces$ mashed potatoes .

3. $\frac{1}{3}\ of\ 2\ ounces$ $= \frac{1}{3}\times 2 =0.67\ ounces$ green beans.

Let us add the above 3 quantities to get total solid food consumed.

Total solid food consumed = 1.50 + 2.25 +0.67 = 4.42 ounces.

So, the answer is 4.42 ounces.

Can someone please explain how to solve this? 1/2x + 3/2 (x+1) - 1/4 = 5 Thank you!!

Snezhnost [94]

Answer:

x = 1.875

Step-by-step explanation:

Step 1: Distribute

1/2x + 3/2(x + 1) - 1/4 = 5

1/2x + 3/2x + 3/2 - 1/4 = 5

Step 2: Combine like terms

4/2x + 6/4 - 1/4 = 5

2x + 5/4 = 5

Step 3: Subtract 5/4 from both sides

2x + 5/4 - 5/4 = 5 - 5/4

2x = 3.75

Step 4: Divide both sides by 2

2x / 2 = 3.75 / 2

x = 1.875

Answer: x = 1.875

Using the given information, the height of the shorter cone is 6.81 cm

<h3>Calculating volume of a cone </h3>

From the question, we are to determine the height of the shorter cone.

First, we will calculate the volume of the first cone

Using the formula for calculating the volume of a cone,

$V = \frac{1}{3}\pi r^{2}h$

Where V is the volume

r is the radius

and h is the height

From the given information,

r = 8.5 cm

h = 10 cm

Then,

$V = \frac{1}{3}\pi \times 8.5^{2}\times 10$

$V = \frac{1}{3}\pi \times 72.25\times 10$

$V = \frac{722.5}{3}\pi$ cm³

Now, for the shorter cone

r = 10.3 cm

Since the two cones have the exact same volume, we can write that

$\frac{722.5}{3}\pi= \frac{1}{3}\pi \times 10.3^{2} \times h$

$722.5= 106.09 \times h$

$h = \frac{722.5}{106.09}$

h = 6.81 cm

Hence, the height of the shorter cone is 6.81 cm.
