ok im sorry but does anyone know 7+(-12)+(-7)??

Answers

Answer:

-12

Step-by-step explanation:

Given the following question:

7 + (-12) + (-7)
Using PEMDAS:
(-12) + (-7) = -19
7 + -19 = -12
= -12

Hope this helps.

Answer:   -12

=========================================================

Explanation:

Let's simplify the 7+(-12) portion first

Draw a vertical number line. Plot a point at 7. Then move down 12 units to arrive at -5

Or you could start at -12 and move up 7 units to arrive at -5

This tells us that 7+(-12) = -5

So the overall 7+(-12)+(-7) turns into -5+(-7)

-----------

Draw another vertical number line, or use the one already drawn in the previous section.

Plot a point at -5. Then move down 7 units to arrive at -12

Or start at -7 and move down 5 units to arrive at -12

Therefore, -5 + (-7) = 7+(-12)+(-7) = -12 is the final answer

-----------

Shortcut:

The 7 and -7 in the original expression add to 0. They cancel each other out. So we're left with -12

Suppose that u and v are two vectors with |u| = 1, |v| = 3 and u · v = −2.
a. Compute |u + v|.
b. Compute |(u + 2v) × v|.

Answers

a. |u + v| = 4

b.  |(u + 2v) × v| = 16

What are vectors?

Vectors are known as quantities having both magnitude and direction.

Given that;

|u| = 1 |v| = 3 u · v = −2

a.  |u + v|

Substitute the values of the vectors

|u + v| = 1 + 3

|u + v| = 4

b.  |(u + 2v) × v|

Expand the bracket

|u. v + 2v² |

But u. v = -2

We then have;

-2 + 2(3)²

-2 + 2(9)

-2 + 18

16

Thus, the values are 4 and 16 respectively.

Arun says if he adds together two mixed numbers, his answer will always be less than the sum of the whole-number parts plus 1. Say 2 counter-examples to show Arun's statement is not true. A counter statement is any example that shows a statement is false

Answers

The two examples can be 1 1/2 & 1 3/4 and 2 2/3 & 1 2/3.

According to Arun,

Sum of two mixed numbers <  Sum of the whole number part +  1

Now, lets take the example as 1 1/2 and 1 3/4

Their sum will be:

1 1/2 + 1 3/4 = 3 / 2 + 7 / 4

= 13 / 4 = 3 1/4

The sum of whole parts = 1 + 1 = 2

Adding 1 to it = 2 + 1 = 3

We can clearly see that 3 1/4 > 3.

It contradicts Arun's statement.

Another example can be:

2 2/3 + 1 2/3 = 8 / 3 + 5 / 3

= 13 / 3 = 4 1/3

Sum of whole part + 1 = 2 + 1 + 1 = 4

4 1/3 > 4

It contradicts Arun's statement.

Therefore, the two examples can be 1 1/2 & 1 3/4 and 2 2/3 & 1 2/3.

Answers

The amount he would pay is $46.40.

How much will he pay?

Percentage can be described as the fraction of an amount that is expressed as a number out of hundred. The sign used to represent percentages is %.

The amount paid = list price of the first shirt + [list price of the second shirt x ( 1 - percentage discount)]

$29 + [$29 x (1 - 0.4)]

In the given diagram, the value of x is 16

Calculating angles

From the question, we are to determine the value of x

In the given diagram, we can observe that (6x + 20)° and 4x° form a linear pair,

Thus, we can write that

(6x + 20)° + 4x° = 180°

Now, we will solve for x

(6x + 20)° + 4x° = 180°

6x + 20 + 4x = 180

10x = 180 - 20

10x = 160

x = 160/10

x = 16

Hence, the value of x is 16

Answers

Answer: he will need to order 1 more new screens

a mobile phone shop has discovered that 35% of all I phones XS screens sold last month are defective.

so probability of defective screen is

x=35/100   (let)

now since he sold 7 phones

so number  of defective screen can be

=x*7

=2.45

since defective screen cant be in decimal

so

taking into consideration that last screen have a chance of getting defective

so he would need 3 screen

he has 2 in stock

so he will need to order 1 more new screens

If payments are made at the end of each period, how much money will be in the account in 18 months? How much interest will Karl have earned? Total amount: Interest earned:

Answers

1. If payments are made at the end of each period, the amount of money that will be in the account in 18 months (future value) is $2,094.46.

2. The total interest that Karl earned will be $294.46.

3. Total amount: $2,094.46

Interest earned = $294.46

What is the future value?

The future value is the future cash deposits compounded at an interest rate for a period.

The future value can be computed using the future value table or future value formula.  It can also be computed using an online finance calculator.

N (# of periods) = 18 months

I/Y (Interest per year) = 21% (or 1.75% monthly)

PV (Present Value) = $0

PMT (Periodic Payment) = $100

Results:

Future Value (FV) = $2,094.46

Sum of all periodic payments = $1,800 ($100 x 18)

Total Interest = $294.46

Thus, the total future amount in the account will be $2,094.46 with an interest of $294.46.
