96, 192, _, 384​

Answers

Answer:

96, 192, 288, 384

Step-by-step:

First we find the difference between the first 2 digits so we subtract them both from each other

192-96

which is

=96

therefore its safe to say that +96 is the rule of the sequence

The sum of -5 and a certain number is 10. What is that number?

Answers

It seems we are looking for a math expression that is the same as English expression you wrote.

The sum is what we get when we add numbers. Therefore, we could restate the English expression as what do we get when we add 5 to the number x? While we do not know what specific number x represents, we do know that if we add 5 to the number x we get 5 plus x. Now the question can be restated as, "How do we write 5 plus the number x?" Do you know the answer now? Does 5 + x sound right? How about x + 5? Both of these expressions are correct as they both represent the sum of 5 and the number x.

Answer: the answer would be 15

Step-by-step explanation: you add 5 to the negitive 5 for it to become 0, then you just add 10.

300, 80, 3 ( partial quotients)

383 (final quotient)

Step-by-step explanation:

7291 is the dividend

19 is the divisor

we have no quotient, so let us make Q our partial quotients

In step 1: Q = 5700 / 19 = 300

In step 2: Q = 1520 / 19 = 80

In step 3: Q = 57 / 19 = 3

14 Is the final remainder in which it isn't a multiple of 9

therefore the final quotient is adding all the partial quotients quotients in step 1, 2 and 3

300 + 80 + 3 = 383

The container that holds the water for the football team is 2/9 full. After pouring in 12 gallons of water, it is 2/3 full. How many gallons can the container hold?

Answers

Answer:

27 Gallons

Explanation:

2/9 of the container is already full, 12 gallons are added. After the 12 gallons are added, 6/9 is full.
12g (gallons) = 4/9 so,
12g + 12g = 24g or 8/9
1/9 = 3g
12g + 12g + 3g = 27 Gallons!!

How to Round:

If the number following the number you're going to round up is 5 or above, (5, 6, 7, 8, or 9), then round up. (E.X. 29 rounded up is 30. Since 9 is above 5, you will round up.

On the other hand, if the number following the number you're going to round is 4 or below, (4, 3, 2, or 1), you don't round up, instead you keep it the same, and if they're are decimals, you turn the following numbers to 0s. (E.X. 32.4536 rounded to the nearest hundredth (32.4536) is 32.45. Since 3 is less than 4, you're not going to round up. The number in the hundredth's place stays the same (5), and the following rest turn to 0s. Leaving you with 32.45

Associative Property:

Identity Property:

Distributive Property

Step-by-step explanation:

Communitive Property:

Addition; When two numbers are added, the sum is the same regardless of the order in which the  numbers are added. (3 + 2 = 5 or 2 + 3 = 5)

Multiplication; When two numbers are multiplied together, the product is the same regardless of the order in which the numbers are multiplied.

(4 x 3 = 12 or 3 x 4 = 12)

Associative Property:

Addition; When three or more numbers are added, the sum is the same regardless of the way in  which the numbers are grouped.

6 + (4 + 3) = 13 or (6 + 4) + 3 = 13

Multiplication; When three or more numbers are multiplied, the product is the same regardless of

the way in which the numbers are grouped.

6 x (4 x 3) = 72 or (6 x 4) x 3 = 72

Identity Property:

Addition; The sum of any number and zero is that number.

(10 + 0 = 10)

Multiplication; The product of any number and one is that number.

(33 x 1 = 33)

Distributive Property:

The sum of two numbers times a third number is equal  to the sum of each addend times the third number. 6(3 + 4)

(Multiply 6 by both numbers, 6 x 3 = 18 and 6 x 4 = 24, and then add the sums; 18 + 24 = 48.

Answer: so it goes -12-->4-->-5--->-7--->-1-->-9-->-6-->6-->45--->-36 And then your there! make sure you look at which numbers are positive and negative in my answer. your welcome :)

Step-by-step explanation:

Note that:

If you multiply 2 negative numbers, your answer will be positive.

If you multiply 1 negative & 1 positive number, your answer will be negative.

If you multiply 2 positive numbers, your answer will be positive.

Start:

-4 x 3 = -12

-2 x -2 = 4

25/(-5) = -5

(-49)/7 = -7

-5 x (1/5) = -1

(-3)(-3)(-1) = (-3 * -3)(-1) = (9)(-1) = -9

(3/4) x -8 = (3 * -8)/4 = 3 * -2 = -6

-18/-3 = 6

-9 x - 5 = 45

12/(-1/3) = 12 * -3 = -36

Finish.

the code will be the sum of all your answers:

For this you need to identify the conversion rate, which is 1 000 000 m^2 / 1 km ^2. Multiply by the thing you're converting from and cancel the units.

(1 000 000 m^2 / 1 km ^2) x 0,12 km^2 = 120 000 m^2 (the km^2 cancels out, leaving you only with your target unit of m^2)

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

On Friday, the number of friends Sharon called 4 friends

On Saturday, the number of each of those 4 friends called 4 different friends.

Therefore, the number of friends on Saturday = 4 × 4

= 16

The number of friends called on, Sunday = 16 × 4

= 64

Hence, the number of friends called on Sunday is; 64.
