Answer:

The price before tip ,Mrs. Henry's move is 351.9 $

Step-by-step explanation:

Given:

Total bills of 414 $ in which 15 % is tip

To Find:

What is the price before tip, Mrs. Henry's move

Solution:

Total bill amount is 414$

And 15 % is tip bill and 85 % is bill before tip

So,

85 % of total bill can give price before tip

calculate 15 % and subtract from total bill.

So 85 % of 414=0.85 *414

=351.9 $

15 % 414=0.15 *414

=62.1 $

Price before Tip is =414$ -62.1 $

=351.9$

So BY Both ways we can get same answer i.e. 351.9 $

2. The length of a rectangle is 5 feet more than the width. The perimeter of the rectangle is

nevsk [136]

In order to solve this let us for at assume that the value of the width is X. Therefore the length will be x+5.

We can now write an equation:

(X+5) + (X+5) + X + X = 58

Combining like terms we should get
4X + 10 = 58

Now subtract 10 from both sides to get
4x = 48

Divide by 4 now and you should get

X = 12

Now we know the value of X and therefore the width.

Suppose that two cards are randomly selected from a standard 52-card deck. (a) What is the probability that the first card is

ser-zykov [4K]

Answer:

(a) $\frac{1}{17}$ (b) $\frac{1}{16}$

Step-by-step explanation:

GIVEN: Suppose that two cards are randomly selected from a standard $52$ card deck.

TO FIND: (a) What is the probability that the first card is a club and the second card is a club if the sampling is done without replacement? (b) What is the probability that the first card is a club and the second card is a club if the sampling is done with replacement.

SOLUTION:

(a)

Probability that first card is club $P(A)=\frac{\text{total club cards}}{\text{total cards}}$
