hi amariharrisdagoat :D

Given :

Terry increased the size of his rectangular garden this summer. He increased to length by 50% and the width by 20%.

To Find :

By what percentage has his garden changed with these changes.

Solution :

Let, initial length and breadth is x and y.

So, initial area = xy .

Size after increasing them :

y' = y + 0.50y

y' = 1.5y

x' = x + 0.2x

x' = 1.2x

Final area = (1.5y)(1.2x) = 1.8xy

So, percentage increase is :

[tex]= \dfrac{new-original}{original }\times 100\%\\\\= \dfrac{1.8xy -xy}{xy }\times 100\\\\=80 \%[/tex]

Therefore, percentage increase in are is 80%.

Hence, this is the required solution.

Answer:

$775 profit

Step-by-step explanation:

Here, we want to know how much profit or loss Jack made;

he sold 300 shares at $15.25

Amount lost on this will be;

(17.85-15.25) * 300 = -$780

The number of shares he sold at $18 will be the 250 he bought now, and the 200 left unsold before

So profit now will be;

200(18-17.85) + 250(18-11.9)

= $30 + $1525 = $1555

So he made $1555 and lost $780

The amount of profit made is $1555-$780 = $775

Answer:

  A(n) = 5 +3(n -1)

Step-by-step explanation:

The first term is ...

  A(1) = 5

The common difference is ...

  d = 8 - 5 = 3

Then the desired formula is ...

  A(n) = A(1) +d(n -1)

  A(n) = 5 +3(n -1)

Answer: 60 pizzas

Step-by-step explanation:

From the question, we are informed that the student council plan to order 2 cheese pizzas for every 3 pepperoni pizzas they order.

Since 36 pepperoni pizzas are ordered for the dance, the number of cheese pizzas ordered will be:

= 36 × 2/3

= 24 cheese pizzas

The total pizza ordered will now be:

= Cheese pizzas + Pepperoni pizzas

= 24 + 36

= 60 pizzas

Answer:

X=13. y=5 AC=20

Step-by-step explanation:

To do this we first have to find the value of x... giving the fact that DE is a mid segment, We know that the length of BC is double the length of DE this means that the length of BC equals 16. So, to equal 16 x will have to equal 13 so 13 + 3 = 16. Now we will find the value of y. We do this by looking at the length of ae and ec. AE equals EC so now that we know x equals 13 we can do 13 minus 3 equals 10 for AE. since EC has to equal 10 we can do 10 minus 5 which equals 5. We now know that y equals 5. We can now add this all up to find the length of AC. We would do 10 + 10 = 20. Hope this helps!

The length of AC from the diagram is 25

To get the value of x and y, we will use the similarity theorem of a triangle

BC = 2DE

x + 3 = 2(8)

x + 3 = 16

x = 16 - 3

x = 13

Hence BC = 16

From the given figure;

AE/DE = AC/BC

x-3/8 = (x-3+y+5)/x+3

10/8 = 15+y/13

130 = 8(15+y)

130 = 120 + y

y  = 10

Get the length of AC

AC = 13-3+10+5

AC = 25

Hence the length of AC from the diagram is 25

Answer:

x = 8

y = 5

Step-by-step explanation:

Let

x and y = the two positive numbers

a. 3x + 2y = 34 (1)

b. 1/2x + 2y = 14 (2)

Solve the simultaneous equation

3x + 2y = 34 (1)

1/2x + 2y = 14 (2)

Subtract (2) from (1)

3x - 1/2x = 34 - 14

6x-x/2 = 20

5/2x = 20

x = 20 ÷ 5/2

= 20 × 2/5

= 40/5

= 8

x = 8

Substitute x = 8 into (1)

3x + 2y = 34 (1)

3(8) + 2y = 34

24 + 2y = 34

2y = 34 - 24

2y = 10

y = 10 / 2

= 5

y = 5

Answer:

Step-by-step explanation:

Answer:

3.4 kg

0.06 kg

Step-by-step explanation:

Given that:

Birthweight follows a normal distribution :

Mean weighf (m) = 3.4 kg

Standard deviation (σ) = 0.6 kg

Sample size (n) = 100 new born babies

calculate the sample mean birth weight for each sample. Calculate the mean and standard deviation of the sampling distribution

The sample mean birth weight = population mean birth weight for a normal distribution according to the central Limit theorem.

Hence, sample mean birth weight = 3.4kg

Standard deviation of sampling distribution = standard error = σ/√n

0.6 / √100

= 0.6 / 10

= 0.06 kg

Using the Central Limit Theorem, it is found that:

In this problem:

Hence, the mean of the sampling distribution is of 3.4 kg and the standard deviation is of 0.06 kg.

Answer:

I agree with both of them because they are both correct

Step-by-step explanation:

See attachment for complete question;

Slope (m) is calculated using the following formula:

[tex]m = \frac{Rise}{Run}[/tex]

Where

[tex]Rise = Vertical\ Distance[/tex]

[tex]Run = Horizontal\ Distance[/tex]

From the attachment, we have the following:

Triangle A

[tex]Rise = 6\ units[/tex]

[tex]Run = 4\ units[/tex]

So:

[tex]m = \frac{Rise}{Run}[/tex]

[tex]m = \frac{6}{4}[/tex]

In this case, Mai is correct:

Triangle B

[tex]Rise = 1.5\ units[/tex]

[tex]Run = 1\ units[/tex]

So:

[tex]m = \frac{Rise}{Run}[/tex]

[tex]m = \frac{1.5}{1}[/tex]

[tex]m = 1.5[/tex]
