Answer:

530.3

Step-by-step explanation:

You want to subtract 620-89.7. If you want to use the standard algorithm you have 620.0-89.7. You "borrow" from the 2 in the tens place, then "borrow" from the ones place. To subtract 10-3 tenths. Then you subtract the ones place which is 9-9=0 ones. Now you subtract 62-8=53 tens. So you have 530.3 as the difference.

Answer:

total distance = 3300 ft

Step-by-step explanation:

we know here displacement S is in vector form that is

$\vec{S} = \vec{S1} +\vec{S2}+\vec{S3}+\vec{S4}$ ......................1

$\vec{S} = (3\hat{i}+6\hat{j}) + (-7\hat{i}-3\hat{j})$

and

$\vec{S} =(-4\hat{i}+3\hat{j})$

and

magnitude is

$\left| \vec{S} \right| = \sqrt{(-4)^2+3^2}$

$\left| \vec{S} \right| = \sqrt{25}$

$\left| \vec{S} \right| = 5$

so here distance from home to cafe is

S = 5 × 660

total distance = 3300 ft

To use an automated teller machine at a certain bank, you must enter a 4-digit code, using the digits 0 dash 9. How many 4-d

oksian1 [2.3K]

Answer:

100000 4-digit codes

Step-by-step explanation:

using the digits 0 dash 9, we want to pick 4 digits code.

The total number of digits available for us to pick from is 10(0 to 9 has 10 digits). We want to pick the 4 digits code and repetition is allowed. This is a case where we apply permutation with repetition. It is different when repetition is not allowed. It gives more possible outcomes than when repetition is not allowed. We will apply the formula, n^r

Where n is the total number of digits we want to choose from and it is equal to 10

r is the number of digits we can choose and it is equal to 4.

Number of possible 4 digit codes

= 10^4 = 100000
