A) Actual velocity is found as the sum of two vectors representing the two velocities.

Since the directions are at 90° (N and E), we will use Pythagorean to find the actual velocity.

b) Let the direction the ship sails in is x. Use trigonometry to find the angle from the North:

Answer: y = 1.2

Step-by-step explanation:

1.5(3y+2) - y = 2(8y-6)

4.5y + 3 - y = 16y - 12

3.5y + 3 = 16y - 12

-3. -3

3.5y = 16y - 15

-16y. -16y

-12.5y = -15

—— —— <—fraction symbol to divide

-12.5. = -12.5

y. =. 1.2

Answer:

5y=6

Step-by-step explanation:

4.5y+3-y=2(8y-6

16y-12

3.5y+3-16y=-12

12-3

-12.5y=-12-3=15

Answer:

The factor which is used to convert feet per minute into miles per minute is:

1 ft per minute=0.000189 miles per minute.

( since, 1 ft.= 0.000189 miles )

Step-by-step explanation:

Conversion factor--

A conversion factor is a factor which is used to convert one unit to another by multiplication or division by a specified number.

We know that:

1 miles= 5280 ft.

This means that:

1 ft.=1/5280 miles

i.e. 1 ft.= 0.000189 miles.

Hence, 1 ft per minute=0.000189 miles per minute.

Ching Weng spend 39.75 less then she budgeted on the personal items for the month of January.

We have Ching Weng's budget and expenses for personal items.

We have to determine how much more or less did she spend than she budgeted.

A budget is an estimation of revenue and expenses over a specified future period of time.

According to the question -

The total amount kept by Ching Weng as budget = $95 + $15 + $20 = $130

The total expenses of Ching Weng = $60.75 + $7.85 + $21.65 = $90.25

Since, expenses are less than budget, she spend less than she budgeted. Thee amount saved by her is =

Total budget - total expenses = 130 - 90.25 = $39.75

Hence, Option A is the correct alternative.

Answer:

Volume = 9424.78 cubic centimeters

Capacity = 9.425 liters

Step-by-step explanation:

Volume of a cylinder given r = radius and h = height is
V = πr²h

Given r = 10 and h = 30

V = π (10)² . (30) ≈ 9424.78  cubic centimeters

1 liter = 1000 cubic centimeters this works  out to
9424.78/1000 = 9.42478 ≈ 9.425 liters

For less than 6 hours, Hank's Movers charge less.

Acme movers charge $210 plus $20 per hour, so if they work for x hours they charge:

A(x) = $210 + $20*x

Hank's movers only charge $55 per hour, so here the linear equation is:

H(x) = $55*x

They charge the same amount when:

A(x) = H(x)

$210 + $20*x = $55*x

Now we can solve that to get:

$210 + $20*x = $55*x

$210 = $55*x - $20*x = $35*x

$210/$35 = x = 6

So, for 6 hours, both companies charge the same amount.

For less than 6 hours, Hank's Movers charge less.

Step-by-step explanation:

Since the exponent is negative.  The number written in standard form is much smaller than 2.  How much smaller?  We need to move the decimal 5 places to the left.   When we do not see the decimal it is at the end of the number.

We do not see the decimal in 2, so we know it is to the right of the 2.  If I move that 5 places to the left, I get. 0.00,002

The cost of the membership after a discount of $ 136 will be $ 204.

We are given that:

a local gym is giving a discount for the promotional offer it has to make.

Discount percentage = 40 %

Cost of the annual membership = $ 340

Discount = 40 % of $ 340

Discount = 40 / 100 × $ 340

Discount = 0.4 × $ 340

Discount = $ 136

So, the cost of annual membership after discount will be:

Cost = $ 340 - $ 136

Cost = $ 204

Therefore, the cost of the membership after a discount of $ 136 will be $ 204.

Answer:

Step-by-step explanation:

8 liters of 30 percent vinegar solution was mixed.

Percent or percentage is defined as the value for every 100. the simple way to calculate percentage is by dividing the data with the whole data and multiplying it by 100.

4 liters of 15 percent vinegar solution contains:

(15/100)×4 liters of vinegar=0.6 liters

x liters of 30 percent vinegar solution contains:

(30/100)× x liters of vinegar=0.03x liters

Therefore the total vinegar in the 25 percent solution is (0.6+0.3x) liters.

Total volume of the solution is (x+4) liters

(x+4) liters of 25 percent solution contains:

(25/100)×(x+4) liters =(0.25x+1) liters

Now we can equate both values to calculate the value of x from a linear equation:

(0.6+0.3x)=(0.25x+1)

or, 0.05x=1-0.6

or, x= 8 liters

Hence 8 liters or 30 percent solution was mixed.
