Arrange the 9 digits in three arithmetic sums. Using three of the four operations of addition, subtraction, multiplication, or d

ivision. Use no signs except the signs using those operations. Here is an example
You must use digits 1 - 9 and only ONCE

3 + 4 = 7

9 - 8 = 1

30 / 6 = 5

The above example is not correct, because it does not contain 2, and three is repeated.

Answer:

i. 5 + 4 = 9

ii. 2 x 3 = 6

iii. 8 - 7 = 1

Step-by-step explanation:

Given: The basic arithmetic operations: addition, subtraction, multiplication or division.

           Digits from 1 - 9

Using three arithmetic operations - addition, subtraction, multiplication, and the given digits, the following three expressions can be formed:

i. 5 + 4 = 9

ii. 2 x 3 = 6

iii. 8 - 7 = 1

It can be observed that there is no repetition of digits in the above expressions as required.

2) Linear pairs of angles are supplementary

This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.

What is 9. 24 repeating as a mixed number in simplest form?
Serga [27]

The recurring decimal number 9.2424... expressed in mixed number is 9\frac{24}{99}

In the given decimal number, 2 is the digit at the tenth place and 4 is the digit at the hundredth place.

The fraction part \frac{24}{99} in the simplest form is \frac{8}{33}

The whole number part is 9.

Therefore, the number 9.2424... as a mixed number in the simplest form is 9\frac{8}{33}

write the standard form of the equation of the circle with endpoints of a diameter at the points (9,2) and (-7,5)
AnnyKZ [126]

Answer:

Step-by-step explanation:

Answer:

(x-1)²+(y-3.5)² = 265/4

Step-by-step explanation:

first find the midpoint (center of the circle)

(9+-7)/2, (2+5)/2

(1, 3.5) = center

then distance formula to find diameter

√(9- -7)²+(2-5)²=√256+9 = √265

The radius is half the diameter = (√265)/2

Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center

Now you can plug everything in.

(x-1)²+(y-3.5)² = 265/4
