How do you solve this problem 19 1/6 - 14 1/3

Answers

Answer 1

Answer: = 115/6 ÷ 43/3

= (115 × 3) / (43 × 6)

= 345/258

= 115/86

= 1 29/86

Answer:

$z_1=(5√(2))^(1/3)cis((7\pi)/(12))$

Step-by-step explanation:

To find the roots of the complex number you use the following formula:

$z=re^(i\theta)\n\nz_k= (r)^(1/n)[cos((\theta+2\pi k)/(n))+sin((\theta+2\pi k)/(n))];\ \ k=0,1,2..n-1$ (1)

in this case the polar number in polar form is:

$r=√(5^2+5^2)=5√(2)\n\n\theta=tan^(-1)((-5)/(5))=-45\°$

By replacing in (1) you obtain:

$z_0=(5√(2))^(1/3)cis((-\pi/4+0)/(3))\n\nz_1=(5√(2))^(1/3)cis((-\pi/4+2\pi)/(3))=(5√(2))^(1/3)cis((7\pi)/(12))\n\nz_2=(5√(2))^(1/3)cis((-\pi/4+4\pi)/(3))=(5√(2))^(1/3)cis((15\pi)/(12))$

hence, you have:

One case of books weighs 35 pounds. One case of magazines weighs 23 pounds.A book store wants to ship 72 cases of books and 94 cases of magazines to another store. What is the total weight of the shipment

Answers

Shipment = 72 cases of books + 94 cases of magazines
1 case of books = 35 pounds
1 case of magazines = 23 pounds

Shipment = 72 × 35 + 94 × 23 pounds

72 × 35 = 2520
94 × 23 = 2162

Shipment = 2520 + 2162 pounds

Shipment = 4682 pounds

What is 1.16 rounded to the nearest tenths?

Answers

1.16 rounded to its nearest tenths is 1.2.

What is place value?

The placevalue of a number is given as:

Example:

1234.567

1 = thousand place value

2 = hundred place value

3 = tens place value

4 = ones place value

5 = tenths place value

6 = hundredths place value

7 thousandths place value

We have,

1.16

The number 1 after the decimal point is in the tenthplacevalue.

Now,

Since 6 is greaterthan 5 tenth place value will be rounded to the next number.

So,

1.16 rounded to the nearest tenths.

= 1.2

Thus,

1.16 rounded to its nearest tenths is 1.2.

The answer is 1.2

You want to round to the tenths, and the tenths spot is taken by a 1.
So, you use the 6 (in the hundredths spot) and since it is over 5, you boost it up.
The 1 will now become a 2, so the answer is 1.2.

Word problem on direct variationmoving object, the force acting on the object varies directly with the object's acceleration. When a force of 100 N acts on a certain object, the accelerati
object is 10 m/s. If the force is changed to 90 N, what will be the acceleration of the object?

Answers

Answer:

acceleration would be 9 meters per second squared

Step-by-step explanation:

If quantity "A" varies directly with quantity "B", then we can write:

A = kB

Now, this problem says that force (f) varies directly with acceleration (a). So we can write:

f = ka

Given f = 100 and a = 10, so we substitute and find k (the proportionality constant). Shown below:

f = ka

100 = k(10)

k = 100/10

k = 10

So, we have

f = 10a

Now, force is 90, so what's the acceleration?

90 = 10a

a = 90/10

a = 9

So, the acceleration would be 9 meters per second squared

10, it is because if you round 4, it will be 6 and if you round any number after 5 to the nearest tenth you will get 10
