How many groups of 1/2 days are in 1 week? Write a multiplication equation or a division equation to represent the question, then answer the question. *​

Answers

Answer:

14 groups

Step-by-step explanation:

Given

[tex]Groupings = \frac{1}{2}\ day[/tex]

[tex]Duration = 1\ week[/tex]

Required

Determine the number of group in the week

To do this, we simply divide the duration by the number half day group.

This gives:

[tex]Group = \frac{Duration}{Groupings}[/tex]

[tex]Group = \frac{1\ week}{1/2\ days}[/tex]

Convert week to days

[tex]Group = \frac{7\ days}{1/2\ days}[/tex]

[tex]Group = \frac{7}{1/2}[/tex]

[tex]Group = 7 / \frac{1}{2}[/tex]

Convert to multiplication

[tex]Group = 7 * \frac{2}{1}[/tex]

[tex]Group = \frac{14}{1}[/tex]

[tex]Group = 14[/tex]

Hence, there are 14 groups

Write an equivalent expression to (-0.25x - 3) - (2.5x + 1.7) using the fewest possible terms.

Answers

Answer: -2.75*x - 4.7

Step-by-step explanation:

In the equation we have only one variable, this means that the minimum possible number of terms will be two, one term with x, and one term without x.

We can start with the equation:

(-0.25x - 3) - (2.5x + 1.7)

Now, let's rewrite this as:

-0.25x - 3 - 2.5x - 1.7

(-0.25*x - 2.5*x) + (-3 - 1.7)

Solving the parentheses we get:

-2.75*x - 4.7

That is the equivalent expression that has the fewest possible terms

3x-4 or = to 7


plz help

Answers

Answer:

3 + 4 = 7  which is true.

Step-by-step explanation:

Whenever you have an equation with a plain variable (that is, no exponent included), there is only one number that will work when substituted for x.

To solve it, you have to "undo" what is done to the variable. You also go in the reverse order of operations, so you do the addition/subtract first, then multiplication/division.

You also have to do the same to both sides, kind of like keeping a balance scale in balance.

In this case, we subtract 4 from both sides first:

3x + 4 -4 = 7 - 4

The + 4 - 4 cancel each other out, so you get:

3x = 3

3x means "3 times x" so you divide by 3 to undo it. I will use the / to indicate division:

3x / 3 = 3 /3  

so 1x = 1.

Since 1x is "1 times x" it is the same as x by itself, so:

x=1

AND, if we substitute 1 back into the original equation (the asterisk stands for multiply):

3 * 1 + 4 = 7

3 * 1 is 3, so:

3 + 4 = 7     which is true.

1 is the only number that works.

Hope this helped.

how do I find the value of x in a isosceles and equilateral triangle​

Answers

Depends on where the x is. If in the equilateral triangle, x is the only angle missing then you do whatever two numbers they gave + x = 180 then solve.

If it’s in an isosceles and it’s the same situation, you do x = the side with the same amount of degrees (you will know because there will be a line on the “x” and given side

Anyone can find “v” and “u”??

Answers

Answer:

[tex]v = \frac{16}{3} \: \: and \: \: u = \frac{20}{3} [/tex]

Step-by-step explanation:

In triangle WYZ ,

[tex] {u}^{2} = {4}^{2} + {v}^{2} = 16 + {v}^{2} [/tex]

In traingle WXZ ,

[tex] {(3 + v)}^{2} = {5}^{2} + {u}^{2} [/tex]

Putting the value of U^2 in above eqn.

[tex] = > {(3 + v)}^{2} = 25 + (16 + {v}^{2} )[/tex]

[tex] = > {v}^{2} + 6v + 9 = 41 + {v}^{2} [/tex]

[tex] = > {v}^{2} - {v}^{2} + 6v = 41 - 9[/tex]

[tex] = > 6v = 32[/tex]

[tex] = > v = \frac{32}{6} = \frac{16}{3} [/tex]

Putting the value of V in eqn. below :-

[tex] {u}^{2} = 16 + { (\frac{16}{3} )}^{2} [/tex]

[tex] = > {u}^{2} = \frac{256}{9} + 16[/tex]

[tex] = > {u}^{2} = \frac{256 + 144}{9} = \frac{400}{9} [/tex]

[tex] = > u = \sqrt{ \frac{400}{9} } = \frac{20}{3} [/tex]

Her short stature was probably influenced by the lack of a growth hormone produced by the Budgeting, ethics, pharmaceutical company. Chris Jackson was recently promoted to Controller of Research and Development for BrisC or, a Fortune 500 pharmaceutical company that manufactures prescription drugs and nutritional supplements. The companys total R&amp ; D cost for 2017 was expected (budgeted) to be $5 billion. During the companys midyear budget review, Chris realized that current R&amp ; D expenditures were already at $3.5 billion, nearly 40% above the midyear target. At this current rate of expenditure, the R&amp ; D division was on track to exceed its total year-end budget by $2 billion!In a meeting with CFO Ronald Meece later that day, Jackson delivered the bad news. Meece was both shocked and outraged that the R&D spending had gotten out of control. Meece wasnt any more understanding when Jackson revealed that the excess cost was entirely related to research and development of a new drug, Vyacon, which was expected to go to market next year. The new drug would result in large profits for BrisCor, if the product could be approved by year-end. Meece had already announced his expectations of third-quarter earnings to Wall Street analysts. If the R&D expenditures werent reduced by the end of the third quarter, Meece was certain that the targets he had announced publicly would be missed and the companys stock price would tumble. Meece instructed Jackson to make up the budget shortfall by the end of the third quarter using "whatever means necessary." Jackson was new to the controllers position and wanted to make sure that Meeces orders were followed. Jackson came up with the following ideas for making the third-quarter budgeted targets:1. Stop all research and development efforts on the drug Vyacon until after year-end. This change would delay the drug going to market by at least 6 months. It is possible that in the meantime a BrisCor competitor could make it to market with a similar drug.2. Sell off rights to the drug Martek. The company had not planned on doing this because, under current market conditions, it would get less than fair value. It would, however, result in a one-time gain that could offset the budget shortfall. Of course, all future profits from Martek would be lost. Capitalize some of the companys R&D expenditures, reducing R&D expense on the income statement. This transaction would not be in accordance with GAAP, but Jackson thought it was justifiable because the Vyacon drug was going to market early next year. Jackson would argue that capitalizing R&D costs this year and expensing them next year would better match revenues and expenses.3. Referring to the "Standards of Ethical Behavior for Practitioners of Management Accounting and Financial Management,"4. Which of the preceding items are acceptable to use? Which are unacceptable? What would you recommend Jackson do? Simon is selling candy bars for his class fundraiser. In each box of 56 candy bars, 18 arepeanut, and the rest are dark chocolate.
