13. In a park there are 1596 trees in 42 rows. If each row has the same number of trees, estimate the number of trees in one row, rounded off to the nearest tens.​

Answers

Answer 1

Answer:

The ultimate answer according to the question is is 40 trees in one row.

Step-by-step explanation:

Let no. of trees in one row be X.

There are 42 rows,

or, 42X= 1596

or, X= 1596/42

So, X=38

Now, while rounding off to the nearest ten 38 goes to 40.

The correct answer is 37 ⁹/16

I did the math, and wrote the expression as: (1 ¼)² + 6². but still getting it wrong.....

also should I always convert a mixed number before using it's exponent???

Answers

Answer:

see explanation

Step-by-step explanation:

The sum of the areas of the 2 rooms is

(1 [tex]\frac{1}{4}[/tex] )² + 6² ← change the mixed number to an improper fraction

= ([tex]\frac{5}{4}[/tex] )² + 6²

= [tex]\frac{25}{16}[/tex] + 36

= 1 [tex]\frac{9}{16}[/tex] + 36

= 37 [tex]\frac{9}{16}[/tex]

find the midpoint of the segment with the following endpoints (8,7) and (5,4)

Answers

The midpoint is (6.5, 5.5)
(X1-X2)/2 = 8-5/2 = 1.5

(Y1-Y2)/2 = 7-4/2 = 1.5

Now add (1.5,1.5) to (5,4) u get the mid point (6.5,5.5)

Step-by-step explanation:

A professional golfer is shopping for a new brand of golf ball. He likes most of the features of one particular brand, but he wants to make sure that the brand has a desirable spin rate (the rate at which the ball spins on its axis after being struck by a golf club). To test the spin rate of this new brand of ball, the golfer hits the brand of ball on 100 five-iron shots, and a computer measures the spin rate for each shot. The computer then produces the following histogram summarizing the 100 spin rates: 2520151050Frequency1010242421115000550060006500700075008000Spin rate (in revolutions per minute) Based on the histogram, find the proportion of spin rates in the sample that are greater than or equal to 7000 revolutions per minute.

Answers

Answer:

It's all in the picture. good luck :)

Step-by-step explanation:

Domain : R

Range :   ( - ∞, 0)

(Refer the image attached for complete question)

We have the following function -

k(x) = [tex]-2^{x}[/tex]

We have to determine its domain and range.

What do you mean by domain and range of a function?

For any function y = f(x), Domain is the set of all possible values of y that exists for different values of x. Range is the set of all values of x for which y exists.

According to question, we have -

k(x) = [tex]-2^{x}[/tex]

for x = 0, the function k(0) = 1

The function k(x) has the exponential function ([tex]e^{x}[/tex]) as its parent function.

If we plot the graph of the function k(x), it will look like as shown in the figure attached.

The graph of the function k(x) =  [tex]-2^{x}[/tex] is the reflection of the graph [tex]2^{x}[/tex] along x - axis.

The Domain of the function k(x) : R

The Range of the function k(x) : ( - ∞, 0)

sold it at a profit of 15%.
Find the sale price of the ring.​

Answers

Answer:

CP of ring = 1200

profit % = 15%

Profit amount = 15% 0f 1200 = 180

SP = 1200 + 180 = 1380

Answer:

€ 1380

Step-by-step explanation:

The jeweller bought the ring for €1200 and got a profit of 15% when he sold it. That means,

[tex] = \frac{15}{100} \times 1200 \\ = 180[/tex]

he got €180 more money (which is equivalent to 15% of the portion of the money that he originally paid for the ring).

So, the selling price (the new price of the ring) would be:

= Original price + profit

= €1200 + €180

= €1380

1. Given a right triangle the first angle is ten degrees more than three times the degree measure of the second angle and the third angle is the right angle. What is the angle measurement of the first angle? Doint)​

Answers

Answer:

The first angle is [tex]70^{o}[/tex].

Step-by-step explanation:

Let the measure of the second angle be represented by [tex]x^{o}[/tex].

Thus, the first angle = [tex](3x+10)^{o}[/tex]

Third angle = [tex]90^{o}[/tex]

Sum of angles in a triangle = [tex]180^{o}[/tex]

So that;

[tex]x^{o}[/tex] + [tex](3x+10)^{o}[/tex] + 90 = [tex]180^{o}[/tex]

[tex]x^{o}[/tex] + [tex]3x^{o}[/tex] + [tex]100^{o}[/tex] = [tex]180^{o}[/tex]

[tex]4x^{o}[/tex] = [tex]180^{o}[/tex] - [tex]100^{o}[/tex]

[tex]4x^{o}[/tex] = [tex]80^{o}[/tex]

divide both sides by 4 to have;

[tex]x^{o}[/tex] = [tex]20^{o}[/tex]

The first angle = [tex](3x+10)^{o}[/tex]

                        = ( 3 x 20 + 10)

                        = 60 + 10

                        = [tex]70^{o}[/tex]

Therefore, the first angle is [tex]70^{o}[/tex].

You are working to earn enough money for a vacation which costs 1200.0 dollars. Your take-home pay is $16.50/hour, but you only work 4-hour shifts each day. How many days will it take for you to earn enough money to pay for your vacation if all the money you earn goes towards your vacation

Answers

Answer:

It will take [tex]18\frac{2}{11} days[/tex] to earn enough money to pay for your vacation.

Step-by-step explanation:

From the question,

The total cost of the vacation is 1200.0 dollars, that is $1200.0

Also, you earn $16.50/hour but you only work for 4 hours each day.

First, we will determine how much you earn in a day.

If you work for 4 hours each day and earn $16.50 / hour; then the amount you earn in a day is

$16.50/hour × 4 hour

= $66.00

Hence, you earn $66.00 dollars each day.

Now, to determine the number of days it will take for you to earn enough money to pay for your vacation, that will be

The cost of the vacation divided by the amount earned each day

Cost of the vacation = $1200.0

Amount earned each day = $ 66.00

Hence, the number of days it will take for you to earn enough money to pay for your vacation is

$1200.0 / $66.00

= [tex]18\frac{2}{11} days[/tex] or 18.18 days

Hence, it will take [tex]18\frac{2}{11} days[/tex] to earn enough money to pay for your vacation.
