Answer:

Answer is 6 ways

Step-by-step explanation:

Given that a family wants to visit three different places as Philadelphia, Baltimore, and Washington.

We have to find the number of ways these three can be visited.

Here this is a question of permutation since order matters.

There are 3 cities and these can be visited in 3P3 ways =3!

=3x2x1 =6 ways

There are in total 6 different ways that the family can visit three different places as Philadelphia, Baltimore, and Washington.

Since they are similar both dimensions would have the same ratio. The ratio of 5 and 15 is 3. 15 is 3 times larger than 5, so the unknown dimension is 3 times larger than the known dimension.

3 x 10 = 30

The unknown dimension is 30

In the drawing below, line n is a transversal that intersects two parallel lines. What is the measure of Angle 4?
4vir4ik [10]

Answer:

140°

Step-by-step explanation:

<3 = 40 because they are vertical angles

<3 +<4 = 180 because they are same side interior angles

40 + <4 = 180

Subtract 40 from each side

40-40 + <4 = 180-40

<4 = 140

A TV has an original price of $599. Enter the new price after the given percent of change.
vlabodo [156]

Answer:

The new price = $718. 8

Step-by-step explanation:

Original Price =  $599

Given that the increase is 20%.

i.e.

Thus,

The amount of 20% Percentage increase = 20/100 × 599

                                                                             = 0.2 × 599

                                                                              = $119.8

Therefore,

New price = Original price + 20% increase amount

                 = 599 + 119.8

                  = $718. 8

Therefore, the new price = $718. 8

Luda [366]

Step-by-step explanation:

It depends in the type on interest

Simple Interest

PxRxT

£240 x 0.07x 3 = £50.4

£240 + £50.4 = £290.4

Compound Interest

Px(1+R)^T

£290.4 x (1 + 0.07)³ = £355.7524872= €355.76
