So, We Have:
4y^{2} = 256

We Need To Solve.
Lets Start By Finding the Square Root Of 256.
4y = \sqrt{256} \\
We\ Know\ That\ \sqrt{256} = 16. So,\ The\ Equation\ Becomes:\\
4y = 16\\
Divide\ Both\ Sides\ By\ 4.\\
y = 16/4\\
16/4 = 4,\ So:\\
Y = 4\\
Check:\\
4*4 ^{2} = 256\\
4*4 = 16.\\
16^{2} = 256\\
256 = 256\\
This\ Is\ True.\ So,\ y = 4.

for pet food: how would adopting a process costing system benefit the managers responsible for the production of this product? l
lapo4ka [179]

Job order costing also gives managers the advantage of being able to keep track of individuals' and teams' performance in terms of cost control, efficiency, and productivity. A disadvantage of job order costing is that employees are required to track all materials and labor used during the job.

With the standardization of products, managers track performance, productivity, and costs over time. Process costing allows for greater flexibility when making changes in the production process. Managers can target specific departments' processes or materials to lower production costs.

With process costing, companies track the flow of costs from department to department, rather than tracking costs for each individual item. Each department adds direct labor and manufacturing overhead costs, plus the cost of any raw materials it uses.

A cafeteria made 28.5 liters of lemonade. How many gallons of lemonade did the cafeteria make? (1 gallon is approximately 3.8 li
sergejj [24]

Answer:

7.5 gallons

Step-by-step explanation:

We know that 1 gal = 3.8 L, and we have 28.5 L. So, set up a proportion:

1 gal / 3.8 L = x gal / 28.5 L , where x is the number of gallons the cafeteria made

Cross-multiply:

1 * 28.5 = 3.8 * x

28.5 = 3.8x

Divide by 3.8:

x = 28.5 / 3.8 = 7.5 gallons

Can anybody help me with this one?
Murrr4er [49]

Answer:

  12 cm

Step-by-step explanation:

The rule regarding secants and/or tangents is that the product of distances from their common point to the two intersection points with the circle is the same.

For the tangent the "two" intersection points with the circle are the same point, so ...

  product of tangent lengths = product of secant lengths

  (8 cm)(8 cm) = (4 cm)(4 cm +x)

Dividing by 4 cm gives ...

  16 cm = 4 cm + x

  12 cm = x

Which equations are equivalent to Three-fourths + m = negative StartFraction 7 over 4 EndFraction? Select three options. m = Sta
marishachu [46]

Answer:

1)  m = negative StartFraction 10 over 4 EndFraction

2) m = negative five-halves

3) m = -\frac{7}{4} - \frac{3}{4}

Step-by-step explanation:

<u>The given equation is:</u>

=> \frac{3}{4} +m = -\frac{7}{4}

Subtracting 3/4 to both sides

=> m = -\frac{7}{4} - \frac{3}{4}

=> m = \frac{-10}{4}

=> m = -\frac{5}{2}
