The amount that a charter boat captain charges a group to go deep-sea fishing is shown. If the group tips the captain 17%, what
jenyasd209 [6]

The total amount that the captain receives for the fishing trip=850+17 percent $994.5

What is the percentage?

  • The Latin word "per centum," which means "by the hundred," was the source of the English word "percentage."
  • Fractions with a denominator of 100 are called percentages. In other words, it is a relationship where the value of the entire is always assumed to be 100.
  • A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.

Amount charged =$850

tip from the group=17 percent

The total amount that the captain receives for the fishing trip=850+17 percent 850

=850+(0.17X850)

=$994.5

The total amount that the captain receives for the fishing trip=850+17 percent $994.5

PLEASE HELP, I DONT UNDERSTAND THIS.....Michael is laying carpet in a perfectly rectangular hall. The area of the hall is 240 sq
Setler79 [48]

Answer:

40 feet

Step-by-step explanation:

We know that the area of a rectangle is represented as lw=a, where l is the length and w is the width.

We already know the width, and we know the area, so we can plug these values into the equation.

l\cdot 6 = 240

Our goal is to now isolate the variable l, and to do this we can divide both sides by 6.

(l\cdot6) \div6 = 240\div6\\\\l = 40

Hope this helped!

PLEASE HELP 20 POINTS

Hello!

A sample of Bromine-82 begins at 80 mL. We are given that this value will decrease by half of its current amount every 35 hours. First, we'll determine the number of times that 35 goes into 140. This will reveal the number of times we should divide the sample by 2:

140 ÷ 35 = 4

We have now proven that there are 4 periods of 35 hours in 140 hours. This means that we will divide the sample in half a total of 4 times, as follows:

1. 80 ÷ 2 = 40
2. 40 ÷ 2 = 20
3. 20 ÷ 2 = 10
4. 10 ÷ 2 = 5

We have now proven that an 80 mL sample of Bromine-82 will be reduced to only 5 mL after 140 hours. Therefore, the correct answer is 5 mL.

I hope this helps!

In order to use a ladder safely, the angle that the ladder forms with the ground should not exceed 70 degree. If you have a ladd
solong [7]

Answer:

Maximum safe height can be reached by ladder = 15.03. ft

Step-by-step explanation:

Given,

Let's assume the maximum safe height of wall = h

angle formed between ladder and ground = 70°

length of ladder = 16 ft

From the given data, it can be seen that ladder will form a right angle triangle structure with the wall

So,from the concept of trigonometry,

Sin70^o\ =\ \dfrac{\textrm{maximum safe height of wall}}{\textrm{length of ladder}}

=>Sin70^o\ =\ \dfrac{h}{16\ ft}

=>\ h\ =\ 16\times Sin70^o

=> h = 16 x 0.9396

=> h = 15.03 ft

So, the maximum safe height that can be reached by the ladder will be 15.03 ft.
