Answer:

\huge\boxed{ \$ \ 8.22}

Step-by-step explanation:

Bill = $54.83

Tip = 15 % of 54.83

[% means out of 100, "of" means to "multiply"]

<u>Tip:</u>

= 15% of 54.83

= 15 / 100 * 54.83

= 0.15 * 54.83

= $ 8.22

\rule[225]{225}{2}

Hope this helped!

Multiply the amount of the bill by the percentage:

54.83 x 0.15 = 8.22

My name is Ann [436]

Answer:

option C

c. least: $101

greatest: $1001

Step-by-step explanation:

A radio station advertises a contest with ten cash prizes totaling $5510. There is to be a $100 difference between each successive prize.

Sum of 10 prizes = 5510

100 is the difference. there is a common difference d=100

So its a arithmetic sequence

the sum formula for arithmetic sequence is

S_n = \frac{n}{2}(2a_1 +(n-1)d)

Sn = 5510, n=10 n d= 100 we need to find out first term a1

5510 = \frac{10}{2}(2a_1 +(10-1)100)

5510 = 5 (2a1 + 900)

5510 = 10a1 + 4500

Subtract 4500 on both sides

1010= 10a1

divide by 10 on both sides

a1 = 101

so first term that is least term is 101

To find out greatest term we use formula

a_n = a_1 + (n-1) d

a(10) = 101 + (10-1)100

= 101 + 900= 1001

greatest is 1001

Ivahew [28]

Answer:

7.81mph

Step-by-step explanation:

Using the pythagoras theorem;

resultant r is expressed as;

r² = 5² + 6²

r² = 25 + 36

r² = 61

r =√61

r = 7.81mph

Hence the resultant speed is 7.81mph
