If one of the numbers you're trying to find the sum of is negative then do the following.

First, find the absolute values for both of the numbers then subtract the smaller amount from the larger amount. Then give the sign from the larger amount.

Find the absolute values of -7 and 5.

|-7| = 7
|5| = 5

Subtract 5 from 7.

7 - 5 = 2

7 is the larger number and it had a negative sign.

So, the answer is -2.

In 1999, there were 9860 Great Danes registered with the American Kennel Club. The number of registered Labrador Retrievers was
jekas [21]

Answer:

153,997 Labrador Retrievers

Step-by-step explanation:

Let's make an equation for this problem. We know that there were 9,860 Great Danes. The number of Labrador Retrievers was 6,997 more than 15 times the number of registered Great Danes. More than can be changed to a plus sign. 15 times the number of Great Danes is 15 times 9,860. The equation is now 15*9,860 + 6,997.

15*9,860 is 147,900

147,900 + 6,997 is 153,997.

When paid flat a round parachute has a diameter of 8 meters. What is the parachute’s circumference
mariarad [96]

Answer:

25.12 meters

Step-by-step explanation:

The circumference of a circle is given by

c=2\pi r (1)

where:

\pi\sim 3.14

r is the radius of the circle

In this problem, the parachute has a diameter of 8 meters:

d = 8 m

The radius of a circle is equal to half of its diameter, so the radius of the parachute is:

r=\frac{d}{2}=\frac{8}{2}=4 m

And therefore, by applying eq.(1) we can find the circumference of the circle:

c=2\pi r=2\cdot 3.14 \cdot 4 = 25.12 m

6. a) Rivka used the last four digits of her
bulgar [2K]

Answer: Her e-mail password is 1048222131

Step-by-step explanation:

You know that a part of Rivka's e-mail password is formed by the last four digits of her telephone number.

The exercise gives you the last four digits of Rivka's telephone number:

1048

Now, in order to find the other numbers, you need to descompose 1048 into its prime factors. Then:

1048=2*2*2*131

Therefore, based on this, you can determine that her e-mail password is:

e-mail\ password=1048222131
