Answer:

no

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.

longest side = 30 , then 30² = 900

20² + 23² = 400 + 529 = 929 ≠ 900

Then the triangle is not right.

andrew-mc [135]

Answer:

(C)1 out of 5,005

Step-by-step explanation:

There are a total of 15 student friends.

Monica wants to invite 6 of her friends.

The number of ways this can be done is:

^{15}C_6=\dfrac{15!}{(15-6)!6!} \\=\dfrac{15!}{9!6!}\\\\=5005

Therefore, the probability that friends Tessa, Guido, Brendan, Faith, Charlotte and Rhianna are chosen

Sara covers the top of a box with squares of paper that are 1 square centimeter: she uses 48 squares with 6 squares in each row.
scZoUnD [109]

Answer:

Sarah makes 8 rows of squares.

Step-by-step explanation:

Given:

Number of squares she uses = 48

Number of squares in each row = 6

We need to find the number of rows she can makes.

Solution:

Let the number of rows she can make be 'x'.

Now we can say that;

Number of rows she can make is equal to Number of squares she uses divided by number of squares in each row.

framing in equation form we get;

x=\frac{48}{6}=8\ rows

Hence Sarah makes 8 rows of squares.

if it's >5, it +1 to the thousand's number (4th number from right),
eg. 4570 rounded off by thousand = 5000 

if <5 then it reduces to 0.
eg. 3489 rounded off by thousand = 3000

for your case, 2,181,465 rounded off to thousand = 2,181,000
