The minute hand on the clock is 10 cm long and travels through an ark of 180° every 18 minutes. which measure is closest to the length of the art the minute hand travels through during this 18 minute period

Answer:

5.5

Step-by-step explanation:

[tex]\frac{1}{2} |x_{1} (y_{2} -y_{3}) + x_{2} (y_{3} -y_{1} ) + x_{3} (y_{1}- y_{2} ) |\\= \frac{1}{2} \times |5(4-5) + 8 (5-2) + 4(2-4) |\\=\frac{1}{2} \times |-5 +24 + -8 |\\=\frac{1}{2} \times 11\\= 5.5[/tex]

Answer:

24 pages per hour

Step-by-step explanation:

72 pages = 3 hours

To find the rate of pages per hour, divide both sides by 3.

72/3 = 24, 3/3=1

24 pages per 1 hour, 24:1

Answer:

266634.11 m^2

Step-by-step explanation:

The following information is given in the question

The ratio of the side of the triangular fields is 6:9:10

And, the perimeter is 2500m

We need to find the area of that field

So

Let us assume the 3 sides be x

Here so the sides be 6x,9x, 10x

Now the perimeter = sum of the length of all sides

2500 = 6x + 9x + 10x

2500 = 25x

x = 100

The three sides would be 600,900 and 1000

Now the area of that field would be

As we know that

The Area of the triangle as per the Heron Formula is

[tex]= \sqrt{s(s-a)(s-b)(s-c)} \\\\= \sqrt{1250(1250-600)(1250-900)(1250-1000)} \\\\= \sqrt{1250(650)(350)(250)} \\\\= \sqrt{71093750000}[/tex]

=  266634.11 m^2

Step-by-step explanation:

The following mistakes could be explained observed from the plotted bar chart presented in the attachment :

1.) The numeric label of the y-axis which shows the number of text messages isn't well scaled, the numbering did not start from 0, hence this is a defect in the scaling of the bar chart.

2.) Looking closely, the plotted bars do not ALIGN well in terms of spacing as the interval between each bar isn't consistent.

3.) Both the x and y axis of the graph are t labeled thus failing to add a good and meaningful description to the plot especially for first time viewers.

Answer:

The perimeter of figure a is 44 inches, the perimeter of figure b is 72 inches.

Step-by-step explanation:

The sides of figure a is 8; 2; 3; 12; 2; 12; 3; 2, to get the perimeter, add all the sides together, which will be 8 + 2 * 2 + 3 * 2 + 12 * 2 = 8 + 4 + 6 + 24 = 12 + 30 = 42 inches. The sides of figure b is 3; 3; 3; 3; 13; 13; 5; 5; 5; 5; 7; 7, to get the perimeter, add all the sides together, which will be 3 * 4 + 13 * 2 + 5 * 4 + 7 * 2 = 12 + 26 + 20 + 14 = 32 + 40 = 72 inches.

Answer:

a) 44

2 + 8 + 2 + 8 + 12 + 12 = 44

b) 72

13 + 13 + 3 +3 +3 +3 +5 +5 +5 +5 +7 +7 = 72

Answer:

(10/3, 2/3)

Step-by-step explanation:

You may find it easier to write these two equations x+y=4 2x-y=6 in a column:

x+y=4

2x-y=6

Adding these together will eliminate y:

3x = 10.  Then x = 10/3.

Substituting 10/3 for x in the first equation results in:

10/3 + y = 4

Clear fractions by multiplying all three terms by 3:

10 + 3y = 12

Then 3y = 2, and y = 2/3.

The solution is (10/3, 2/3)

Step-by-step explanation:

Answer:

Plates are 2.80 Dollars and cups are 1.40 dollars

Step-by-step explanation:

Cups = c

Plates = p

6p + 5c = 23.80 ==> multiply by 6 ==> 36p + 30c = 142.80

7p + 6c = 28.00 ==> multiply by 5 ==> 35p + 30c = 140.00

Now use algebra to have the 30c be on one side and the rest on the other:

36p + 30c = 142.80 | -36p

30c = 142.80 - 36p

35p + 30c = 140.00 | -35p

30c = 140.00 - 35p

Now set them equal to each other about the 30c:

142.80 - 36p = 140.00 - 35p

Use algebra to solve for p:

142.80 - 36p = 140.00 - 35p | +36p

142.80 = 140.00 + p | - 140

2.80 = p

Go back to one of the "30c" equations and plug in the value for p:

30c = 140 - 35p

30c = 140 - 35(2.80)

30c = 140 - 98

30c = 42 | /30

c = 42/30

c = 1.4

Answer:

the cost of 1 plate  $4.1

the cost of 1 cup $1.5

Step-by-step explanation:

6p + 5c = 32.10

7p + 6c=  37.70

Multiply the first by 6

Multiply the second by -5

and then ADD both

36p +30c = 192.6

-35p-30c =  -188.5   (30c is cancelled)

p = 4.1

4.1(6) +5c = 32.10

24.6 +5c = 32.10

5c = 7.5

c= 1.5

1.5(5) =7.5

24.6 + 7.5 = 32.10

Hi there!

Your job, at least on this triangle, is pretty simple. This is a 45-45-90 triangle.

Because this is a 45-45-90 triangle, both legs are 5. That leaves us to find the hypotenuse, x.

And a 45-45-90 triangle's hypotenuse is easy. You just take the measure of one of the legs, or 5 in this case, and stick a [tex]\sqrt{2\\}[/tex] right next to it. So your answer will be:

[tex]5\sqrt{2}[/tex]

I hope this helps! :)

Answer:

[tex]18 = 3 + 5x \\ 5x = 18 - 3 \\ 5x = 15 \\ x = 3[/tex]

Answer:

X = 3

Step-by-step explanation:

18 - 3 = 15 and 3 x 5 = 15. However there is a way to check which would be doing 5 x 1 + 3 and 5 x 2 + 3 and so on and so on until you find your answer.

Answer: 7^3/7^6= 1/343

Step-by-step explanation: We move 7^-6 to a denominator because we cannot have a negative exponent in the numerator.

So it would be 7^3/7^6

Which then would be 7*7*7/7*7*7*7*7*7

Which would equal 343/117649

Simplify and you get 1/343

Answer:

that's 10 kids

Step-by-step explanation:

Start out by finding the area of the square.

a = 4²

a = 16

Since all we have to look at is 1/4 of this square, multiply the area by 1/4.

(16)1/4

4

The area of the triangle is 4.

Now we need the area of the circle.

a = πr²

Sub: a = π(2)²

a = π(4)

Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.

a = 4 - 1/4(π(4))

a = 4 - 1/4π x 1

a = 4 - 1/4π

Now this is where it's supposed to go, considering the fact that π isn't given a value.

Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.

Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.

Uhh good luck I guess this math test is weird
