I need the perimeter of this triangle. Round to the nearest tenth. Quickly please

Answers

Answer 1

Answer:

The perimeter of the triangle is about 17.1 units.

Step-by-step explanation:

The perimeter of a triangle is the sum of its three side lengths.

We can see that the two legs of the triangle both measure five units.

To find the third segment, we can use the Pythagorean Theorem since the x-axis is perpendicular to the y-axis. Recall that:

[tex]a^2 + b^2 = c^2[/tex]

Where a and b are the two legs and c is the hypotenuse.

Our two legs are 5 and 5. Hence:

[tex](5)^2 + (5)^2 = c^2[/tex]

Solve for the hypotenuse:

[tex]\displaystyle \begin{aligned} c &= \sqrt{(5)^2 + (5)^2} \\ &= \sqrt{2(5)^2} \\ &= 5\sqrt{2}\end{aligned}[/tex]

Hence, our perimeter will be:

[tex]\displaystyle P = 10 + 5\sqrt{2} \approx 17.1 \text{ units}[/tex]

In conclusion, the perimeter of the triangle is about 17.1 units.

less than sign and answer A because, on the left you are multiplying 72 by a number less than 1, so the value goes down

Answer:

72 x 3/7 < 72

Step-by-step explanation:

72 x 3/7 = 30 6/7. Therefore 72 is the bigger number.

It was recommended that students drink 48 or more ounces of water.
How could you use a histogram to easily display the number of students
who drank the recommended amount?

Answers

Histograms are used to graph the frequency of data, where the length of the bar represents the frequency.

The number of students that drank the recommended amount of water are 125

Given that

[tex]Recommended = 40\ or\ more[/tex]

The number of students who drank the recommended amount are students whose frequency (i.e. length of bars) is 40 or more

From the histogram (see attachment), only 2 bars are above the frequency of 40.

And the number of students in these bars are: 50 and 75

[tex]Total =50 + 75[/tex]

[tex]Total =125[/tex]

Hence, the number of students that drank the recommended amount of water are 125

A circle is cut from a square piece of cloth, as shown: A square, one side labeled as 34 inches, has a circle inside it. The circle touches all the sides of the square. The portion of the square outside the circle is shaded. How many square inches of cloth are cut from the square? (π = 3.14)

Answers

Answer: 907.9 in^2

Step-by-step explanation:

The square has sides of 34 inches each. A circle drawn in the center and touching the edges would have a diamenter of 34 inches, and thus a radius of (34/2) = 17 inches. The area of a circle is pi*r^2. Area = 3.14*(17)^2.

Area of the circle = 907.9 in^2 That is the material cut from the square.

Need help with 6 I don’t get it

Answers

Answer:

I think the answer may be C or 15

Step-by-step explanation:

Every square is a mile, I found out because there are 13 miles to get to school and it is 13 squares to get to the destination. I counted 15 squares from home to the store (I think)

If I am wrong it could be D, nonetheless its not A or B

Step-by-step explanation:

I think that should be 13 because if you draw a line from home to school it indicates that home to school and grocery store to school it's an isosceles triangle because two opposite sides of the home to school and the school to the grocery store are equal

I think this is a really confusing way to ask all of the following:
What’s the value of the 6 in 558672? It’s 600.
What’s the value of the 3 in 74139? It’s 30.

What do you get when you multiply 600*30? 18,000

Answer: 18,000

Answer:

Step-by-step explanation:

For example, if i gave u 28

The digit two stands for 20, and the digit 8 stands for 8, therefore u call it 28

Each spot has it own name

For example if i gave u the number 12345

5 is in the first spot, therefore 5 x 1 =5

4 is in the tenth spot, therefor 4 x 10 = 40

3 is in the hundred spot, therefore 3 x 100 =300

2 is in the thousand spot, therefore 2 x 1000=2000

1 is in the ten thousand spot, therefore 1 x 10000

=100000

So if u add all these numbers together u will get

12345

OK, so for your question, the 6 in 558672, is in the hundred spot, so 6 x 100 =600

The 3 in 74139 is in the ten spot, so 3 x 10=30

So the product is to multiply them together

600 x 30 =18000
