There were 1,265 people at a boat show. After 1/5 of the adults and 1/3 of the children left, there was an equal number of children and adults at the show. how many people left the show?

Answers

Answer:

I think the answer is 171.

Step-by-step explanation:

Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)

Isabelle is plotting a pentagon on a grid.

So far, she has plotted and connected the three points shown on the grid below.

On a coordinate plane, lines connect points (negative 2, 4), (negative 3, 2), and (0, negative 2).

To find:

To complete the pentagon, choosing only from the points below. (2, 0), (–2, 0), (–2, 4), (2, 4).

How can Isabelle complete her pentagon?

Solution:

Consider the attached figure, while going through the following steps.

A five sided polygon is called the pentagon.

As Isabelle already plotted and connected the three points, we need to connect the remaining 2 points to obtain a pentagon.

So, from the attached figure, it's clear that, Isabelle needs to connect the points (2, 0) and (2, 4).

By plotting and connecting these above points, Isabelle can complete her pentagon.

If 45.78 ÷ 1.7 is written in long division form as long division set up where 17 is on the outside of the division symbol and 45780 is on the inside so that the divisor is written as a whole number, where should the decimal point be placed in the dividend?


Between the 4 and the 5

Between the 5 and the 7

Between the 7 and the 8

Between the 8 and the 0



Please help ill give brainlest

Answers

The dividend will be 457.80 and divisor will be 17.

The divisor is 1.7
The dividend is 45.78
We want 17 that is on the outside of the division symbol, written as a whole number.
45780 is on the inside of the division symbol.
So, to make 17 whole number, we will multiply it by 10. And we will also multiply 10 to 45.78 making it 457.80.
(multiplying with 10 means shifting decimal to one right place. Multiplying by 1000 means shifting decimal to 3 right places)
Hence, the dividend will be 457.80 and divisor will be 17.

Answer:   x = 100

=========================================================

Explanation:

The triangles are similar. We can prove this through the angle angle similarity postulate.

This means we can set up the proportion below to solve for x

(short horizontal)/(long horizontal) = (short vertical)/(long vertical)

12/150 = 8/x

12x = 150*8 .... cross multiply

12x = 1200

x = 1200/12 ... divide both sides by 12

x = 100

------------------

As confirmation:

12/150 = 0.08

8/100 = 0.08

This shows that 12/150 = 8/100
