5600 can be simplified. Say you were to just take the two zeros off the end and you would have 56. Now divide 56 by 7 and you get 8. Add the zeros back to the 8 and your answer is 7 x 800. Hope this helps.

Answer:

<h2>600.</h2>

Step-by-step explanation:

Well, to divide these numbers, we can use certain strategy that fits with out logic. For example, we know that 56 divided by 7 can be done mentally, because it's a simple division that can be immediately solved.

So, 56 divided by 7 is 8, then we add the two zeros to the quotient, because we isolated the first to digit to make the division easier and then we have to add back those zeros.

Therefore the division results in 600.

There are several operations that can be done by using certain strategy, like separating the number in easier parts like we did this time.

Please help round to the nearest tenth
Romashka [77]

Answer:

a = 4.6

b = 4.2

Step-by-step explanation:

to find a, use cos:

⇒ cos = \frac{adjacent}{hypothenuse}

⇒ cos 30 = \frac{13}{a}

cos of 30 is 0.154

⇒ 0.154 = \frac{13}{a}

multiply 13 on both sides:

⇒ 0.154 x 13 = \frac{13}{a} x 13

⇒ 4.62 = a

round to the nearest tenth:

⇒ 4.62 = 4.6

⇒ a = 4.6

to find b, use tan:

⇒ tan = \frac{opposite}{adjacent}

⇒ tan 60 = \frac{b}{13}

tan of 60 is 0.320

⇒ 0.320 = \frac{b}{13}

multiply 13 on both sides:

⇒ 0.320 x 13 = \frac{b}{13} x 13

⇒ 4.16 = b

round to the nearest tenth:

⇒ 4.16 = 4.2

⇒ b = 4.2

A project to build a new bridge seems to be going very well since the project is well ahead of schedule and costs seem to be run
Alecsey [184]

Answer:

Scheduled Variance = $850,000.00

Schedule Performance Index = 1.05

Cost Performance Index = 1.11

Step-by-step explanation:

Note: See the attached excel file for the calculations of Total Actual Cost to Date, Budgeted Cost of Work Scheduled (BCWS), and Budgeted Cost of Work Performed (BCWP).

From the attached excel file, we have:

Total Actual Cost to Date = $15,300,000

Total BCWS = $16,170,000

Total BCWP = $17,020,000

Therefore, we have:

Scheduled Variance = Total BCWP - Total BCWS = $17,020,000 - $16,170,000 = $850,000.00

Schedule Performance Index = Total BCWP / Total BCWS = $17,020,000 / $16,170,000 = 1.05

Cost Variance = Total BCWP - Total actual cost to date = $17,020,000 - $15,300,000 = $1,720,000

Cost Performance Index = Total BCWP / Total actual cost to date = $17,020,000 / $15,300,000 = 1.11
