Bezzdna [24]4 years ago
8 0

Answer:

Y = -7

Step-by-step explanation:

First you have do -32 - 3 because we need to get the 3 out of the equation

Than you have -35 and now you need to get the y by itself, to get the y by itself you have to divide 5y by 5 which cancels out and you have to divide -35 by 5, which is -7

if the person leaves the money in the bank, the time it will take for it to reach the given final amount is 6.3 years.

<h3>What is an interest in banking?</h3>

Interest is simply the amount of money a lender or financial institution receives for lending out money or pays for receiving money.

The formular for calculating compound interest is expressed as;

A = P(1 + r/n)^(n*t)

Where A is final amount, P is initial principal balance, r is interest rate, n is  number of times interest applied per time period and t is number of time periods elapsed.

Given the data in the question;

  • Initial principal balance P = $4000
  • Interest rate r = 5.5% anuually = 5.5/100 = 0.055
  • Final amount A = $5600
  • Time t = ?

We substitute our given values into the expression above.

A = P(1 + r/n)^(n*t)

5600 = 4000(1 + 0.055/1)^(1*t)

5600 = 4000( 1.055 )^t

( 1.055 )^t = 5600 / 4000

( 1.055 )^t  = 1.4

We take log of each sides

0.02325t = 0.1461

t = 0.1461 / 0.02325

t = 6.3

Therefore, if the person leaves the money in the bank, the time it will take for it to reach the given final amount is 6.3 years.

Find x please<br><br><br> 10.3<br><br><br> 9.6<br><br><br> 84<br><br><br> 9
valentinak56 [21]

The 2 small black lines through the sides of the triangle indicate that the 2 sides are the same length.

Because the 2 sides are the same the 2 bottom angles are also the same.


This means that 9x +3 = 84

Now we can solve for x:

9x +3 = 84

Subtract 3 from each side:

9x = 91

Divide both sides by 9:

x = 81 / 9

x = 9

The size of a crowd standing along with a 1/4 mile section of a parade route: 5280 people

<h3>Further explanation </h3>

Comparison is an effort to compare two or more objects in terms of shape or size, or number

Proportional Comparisons are comparisons of two or more numbers where one number increases, the other numbers also increase

Can be formulated

\frac{x1}{y1}=\frac{x2}{y2}

so that if:

x = 2

then

y=\frac{y}{x}\times\:2

While the reversal value comparison is the comparison of two or more numbers where one number increases, the other number decreases in value

Can be formulated

\frac{x1}{y2}=\frac{x2}{y1}

so that if:

x = 2

then

y=\frac{x}{y}\times\:2

The size of a crowd who can see the parade can be calculated using the principle of proportional comparison

  • 1. We calculate the ratio of people and areas that can be occupied

The question stated that 10 people occupy a square measuring 5 feet by 5 feet

means the area occupied by 10 people = 5 ft x 5 ft = 25 ft²

so the ratio is :

\frac{10}{25}

  • 2. We calculate the area of ​​the road that can be occupied when viewing the parade

Because there are 1/4 mile section of a parade route and 5 feet deep on both sides of the street, the total area

1 mile = 5280 ft

1/4 mile = 1320 ft

Total area = 1320 ft x 5 ft (deep) x 2 (both sides of the street) = 13200 ft²

Then the comparison of points 1 and 2 can be used to calculate the total number of people who saw the parade

\frac{10\:people}{25\:ft^2\:area}=\frac{total\:people\:watched}{13200\:ft^2\:total\:area}

Total people =

\frac{10\:\times\:13200}{25}

Total people = 5280 (C)
