What is 7 devided by 245 and show work

agasfer [191]

1. Set up the long division.

245/7

2. Calculate 700 ÷ 245, which is 2 with a remainder of 210.

0.02245/7.4.902.10

3. Bring down 0, so that 2100 is large enough to be divided by 245.

0.02245|/.4.902.100

4. Calculate 2100 ÷ 245, which is 8 with a remainder of 140.

0.028245|/.4.902.1001.960140

5. Bring down 0, so that 1400 is large enough to be divided by 245.

0.028245/7.4.902.1001.9601400
6. Calculate 1400 ÷ 245, which is 5 with a remainder of 175.

0.0285245|7.4.902.1001.96014001225175

7. Therefore, 7 divided by 245 approximately equals 0.0285
7÷245≈0.0285

8. Simplify
0.0285 <------------- Answer :)

Find the distance and midpoint of a segment with the following endpoints: (5,-1) and (-9,-1)

Likurg_2 [28]

Answer:

$d = 14$

$(-2,-1)$

General Formulas and Concepts:

Order of Operations: BPEMDAS
Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
Midpoint Formula: $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Step-by-step explanation:

Step 1: Define

(5, -1)

(-9, -1)

Step 2: Find distance d

Substitute: $d = \sqrt{(-9-5)^2+(-1-(-1))^2}$
Simplify: $d = \sqrt{(-9-5)^2+(-1+1)^2}$
Subtract/Add: $d = \sqrt{(-14)^2+(0)^2}$
Evaluate: $d = \sqrt{196}$
Evaluate: $d = \14$

Step 3: Find Midpoint

Substitute: $(\frac{5-9}{2},\frac{-1-1}{2})$
Subtract: $(\frac{-4}{2},\frac{-2}{2})$
Divide: $(-2,-1)$

The probability of event A occurring is 50%, and the probability of event B occurring is 25%. Events A and B are nonsimultaneous

Misha Larkins [42]

Answer:

The probability of event A occurs but event B does not occur = P(A)* Probability of event B does not occur = 0.375

Step-by-step explanation:

The probability of event A occurring = 50% = 0.5

The probability of event B occurring = 25% = 0.25

Events A and B are non simultaneous events.

The probability of event B does not occur = 1 - P(B)

= 1- 0.25

= 0.75

So the probability of event A occurs but event B does not occur = P(A)* Probability of event B does not occur

= 0.5*0.75

= 0.375

Thank you.
