Answer:

185 minutes.

Step-by-step explanation:

It is possible to model an equation for this, such that

$0.10x + 14.80 = 0.08x + 18.50$

where x represents the number of minutes.

Then, you solve for x:

$0.10x + 14.80 = 0.08x + 18.50 \\ 0.02x = 3.70 \\ x = \frac{3.70}{ 0.02} \\ x = 185$

Three friends Steve, Jake and Jodie shared a pizza. Steve ate 2/5 of the pizza and Jake ate 1/4

nlexa [21]

Note that they together ate all of the pizza.
Therefore the total fractions they ate should add up to 1.

By letting the fraction Jodie ate be x.

x + 2/5 + 1/4 = 1
x = 7/20

The answer is 7/20.

xand y are light house. y being 20km due east of x and from a ship due south of x the bearing of y was 055°. what is the distanc

leonid [27]

Answer:

I) |xz| ≈ 28.6 km

II) |yz| ≈ 34.8 km

Step-by-step explanation:

Let's assume that the position of ship due south of x is z (aà pictor representation of the question is attached)

|xy| = 20 km, |xz| = ?, |yz| = ?, θ(y) = 55°

Using Trigonometric ratio - SOHCAHTOA

I) Tan θ = |xz| ÷ |xy| ⇒ Tan 55° = |xz| ÷ 20

|xz| = 20 * Tan 55 = 20 * 1.428

|xz| = 28.56 km

|xz| ≈ 28.6 km

II) Cos θ = |xy| ÷ |yz| ⇒ Cos 55° = 20 ÷ |yz|

|yz| * Cos 55° = 20 ⇒ |yz| = 20 ÷ Cos 55°

|yz| = 20 ÷ 0.574 = 34.84 km

|yz| ≈ 34.8 km

What is 1/6 divided by 1/2/3 in simplest form

Bess [88]

Answer:

Step-by-step explanation:

Given :

$\frac{1}{6}$ divided by $\frac{1/2}{3}$

Now, it can be solving as:

$\frac{1/6}{\frac{\frac{1}{2} }{3} } \\=\frac{\frac{1}{6} }{\frac{1}{6} } \\=1$

Simplest form of given equation is 1
