unit rate for typing 34 words in a minute in a half

Answers

Answer:

Rate is 1.1333 words per second

Step-by-step explanation:

We understand rating as frequency or speed of doing something per time (seconds mainly)

[tex]{ \green{ \tt{rate = \frac{item \: quantity}{time} }}} \\ [/tex]

Let's find rate in terms of seconds (words per second)

[tex]{ \rm{rate = \frac{34 \: words}{ (\frac{1}{2} \times 60) \: seconds} }} \\ \\ { \rm{rate = \frac{34}{30} }} \\ \\ { \rm{rate = 1.133 \: \: words \: per \: second}}[/tex]

Identify the angle of depression.

Answers

Answer:

4

Step-by-step explanation:

An angle of elevation is the angle formed by a horizontal line and a line of sight to a point above the line.

An angle of depression is the angle formed by a horizontal line and a line of sight to a point below the line.

∠3 is an angle of elevation because it is formed by the line of sight that is above the horizontal line.

∠4 is an angle of depression because it is formed by the line of sight that is below the horizontal line.

∠5 is neither an angle of depression nor an angle of elevation because it is not formed by the horizontal line and the line of sight.

∠6  is an angle of elevation because it is formed by the line of sight that is above the horizontal line.

Therefore, the angle of depression is ∠4.

Zack has 2 feet of balsa wood. he needs twice that amount to finish a project. the cost is $0.05 per inch. how much will the balsa wood cost zack.

Answers

Answer:

$1.2

Step-by-step explanation:

There is 12 inches in a foot, and if he needs twice the amount he already has which is 4 then you would multiply 0.05 times 24 and you would get $1.2

Answer: $1.20 for 2 feet of balsa wood

Step-by-step explanation: There are 12 inches in 1 foot, and 24 inches in 2 feet. The cost per inch is 0.05, multiplying 24 (inches) x 0.05 (the cost per inch) would equal $1.20

Use the graph above to complete problems 1 - 5.

Mary is planning a costume party. She spent $375.00 as shown on the graph. How much of the money was spent, to the nearest dollar, on the following items?

1) On decorations?

2) On food?

3) On party hall rental?

4) On prizes?

5) On invitations?

Answers

This one is extremely simple, and we can use the color coded pie chart to find the cost of each of the 5 things.

For the first, decorations, Mary spent $?? as shown by the blue triangle on the pie chart. Let’s get the other ones first to total the money left over.

For the second, she spent $65 on food, as shown by the green triangle on the pie chart.

For the third, she spent $80 on party hall rental, as shown by the blue triangle on the pie chart.

For the fourth, she spent $30 on prizes, as shown by the dark blue triangle.

And for the fifth one, she spent $45 on invitations. A bit too expensive if you ask me.

Then we add all the costs together, and get 220. After adding the extra costs such as candy, costumes, and music, we get a total of $345. We would subtract this from $375 to get a total of $30 left over, which was spent on decorations. The ??? value of the light blue triangle is $30.

Hope this helps!

If f(x)=(4x-3) / 2 and g(x) =(2x+3) / 4, which of the following is true?

A f(g(x)) =1
B f(g (x)) = 0
C f(g(x))=-1
D f(g(x)) = x

Answers

Answer:

f(g(x))= x

Step-by-step explanation:

f(x)=(4x-3)/2

g(x) =(2x+3)/4

f(g(x)) means use the value obtained from g(x) in the equation defined by f(x).  Since g(x) =(2x+3)/4, we can substitute (2x+3)/4 in place of the x in f(x).

If f(x)=(4x-3)/2 then use the expression (2x+3)/4 in place of "x" in (4x-3)/2

f(x)  =    (4x-3)/2

g(x) =       (2x+3)/4

f(g(x))=(4((2x+3)/4)-3)/2

f(g(x))=(((8x+12)/4)-3)/2

f(g(x))= (2x+3-3)/2

f(g(x))= 2x/2

f(g(x))= x

Assume that an economy has 1,000 workers, each working 2,500 hours per year. if the average real output per worker-hour is $20, then total output, or real gdp, will be

Answers

Answer:

  $50,000,000

Step-by-step explanation:

You want to know the total output (real gdp) of 1000 workers, each working 2500 hours producing real output of $20 per hour.

GDP

The output, called "gross domestic product" or GDP, is the total output of all workers for the hours they work:

  (1000 worker) × (2500 hours/worker) × ($20/hour) = $50,000,000

The GDP will be $50,000,000 or 50 million dollars.

Which of the following proves ABC= DEF?

Answers

Answer: A

Step-by-step explanation:

In the diagram, we see that we have two pairs of congruent angles, so it is going to be either ASA or AAS congruence.

To determine if it is ASA or AAS congruence, we can use the fact that for ASA, the side is included between the congruent angles, whereas in AAS, the side isn't.

Since the congruent side is included between the two angles, there is ASA congruence.

You need to invest $1000 in a bank account and are give two options. The first option is to earn $50 every month you leave the money in the account. The second one is to earn 3% interest each month. Describe each of these two functions and make a table of values for each for several months. Which account would you choose?

Answers

Answer:

Option 1

Earn $50 every month.

Let x = number of months the money is left in the accountLet y = the amount in the accountInitial amount = $1,000

[tex]\implies y = 50x + 1000[/tex]

This is a linear function.

Option 2

Earn 3% interest each month.

(Assuming the interest earned each month is compounding interest.)

Let x = number of months the money is left in the accountLet y = the amount in the accountInitial amount = $1,000

[tex]\implies y = 1000(1.03)^x[/tex]

This is an exponential function.

Table of values

[tex]\large \begin{array}{| c | l | l |}\cline{1-3} & \multicolumn{2}{|c|}{\sf Account\:Balance} \\ \cline{1-3} & \sf Option\:1 & \sf Option\:2 \\\sf Month & \sf \$50\:per\:mth & \sf 3\%\:per\:mth \\\cline{1-3} 0 & \$1000 & \$1000 \\\cline{1-3} 1 & \$1050 & \$1030 \\\cline{1-3} 2 & \$1100 & \$1060.90 \\\cline{1-3} 3 & \$1150 & \$1092.73 \\\cline{1-3} 4 & \$1200 & \$1125.51 \\\cline{1-3} 5 & \$1250 & \$1159.27 \\\cline{1-3} 6 & \$1300 & \$1194.05 \\\cline{1-3} 7 & \$1350 & \$1229.87 \\\cline{1-3}\end{array}[/tex]

From the table of values, it appears that Account Option 1 is the best choice, as the accumulative growth of this account is higher than the other account option.

However, there will be a point in time when Account Option 2 starts accruing more than Account Option 2 each month.  To find this, graph the two functions and find the point of intersection.

From the attached graph, Account Option 1 accrues more until month 32.  From month 33, Account Option 2 accrues more in the account.

Conclusion

If the money is going to be invested for less than 33 months then Account Option 1 is the better choice.  However, if the money is going to be invested for 33 months or more, then Account Option 2 is the better choice.
