Answer:

$6.40

Step-by-step explanation:

We first multiply 1.20 by 3 so we can find the price for 3 parcels. We then subtract the result by 10 to get the change Late should get

10-3(1.20)

=10-3.60

=6.40

The time it takes runners to complete a certain marathon are normally distributed with a mean of 4.6 hours and a standard deviat

Yuki888 [10]

The time for this z-score is 3.28.

The formula for z-scores is

z = (X-μ)/σ

Using our information, we have

-1.2 = (X-4.6)/1.1

Multiply both sides by 1.1:
-1.2(1.1) = X - 4.6
-1.32 = X - 4.6

Add 4.6 to both sides:
-1.32 + 4.6 = X - 4.6 + 4.6
3.28 = X

MatroZZZ [7]

Answer: $76.85

Step-by-step explanation:

Your bill:

47 + (47 * 15%) = ?

47 + (7.05) = 54.05

Eliza's bill:

19 + (19 * 20%) = ?

19 + 3.8 = 22.8

22.8 + 54.05 = 76.85

City A is due north of City B. Find the distance between City A (36 degrees 6 prime36°6′ north latitude) and City B (21 degre

vitfil [10]

Answer:

distance = 994.75 miles

Step-by-step explanation:

given data

City A = 36°6′ = 36° + $\frac{6}{60}$ = 36.1° = 36.1° × $\frac{\pi}{180}$ = 0.6297 rad

City B = 21°42′ = 21° + $\frac{42}{60}$ = 21.7° = 21.7° × $\frac{\pi}{180}$ = 0.3785 rad

multiply by π/180 to convert the degree to radian

radius of Earth = 3960 miles

to find out

distance between City A and City B

solution

we first get here central angle between A and B city is

central angle between A and B city = 0.6297 rad - 0.3785 rad

and

now by arc length so we get distance

distance = 3960 miles × (0.6297 rad - 0.3785 rad )

distance = 994.75 miles
