The over all percent increase in Bill's stock over the two days is 4%

Step-by-step explanation:

The given is:

We need to find what was the overall percent increase in Bill's stock over the two days

Assume that Bill buys the stock by $x

∵ Bill buys the stock by $x

∵ The stock decreases by 20% on the first day

- Find the 20% of x

∵ 20% × x = [tex]\frac{20}{100}[/tex] × x = 0.2 x

∴ The cost at the end of the 1st day = x - 0.2 x = 0.8 x

∵ The stock increases by 30% of its value at the end of the 1st day

- Find the 30% of 0.8 x

∵ 30% × 0.8 x = [tex]\frac{30}{100}[/tex] × 0.8 x = 0.3 × 0.8 x = 0.24 x

∴ The cost at the end of the 2nd day = 0.8 x + 0.24 x = 1.04 x

To find the percentage of increased find the increasing amount and divide it by the original cost, then multiply the quotient by 100%

∵ The increasing amount = 1.04 x - x = 0.04 x

∵ The percentage of increase = [tex]\frac{0.04x}{x}[/tex] × 100%

∴ The percentage of increase = 0.04 × 100% = 4%

The over all percent increase in Bill's stock over the two days is 4%

Hope this helps.

The required simplified value of the given number (-5)² would be 25.

A perfect Square is defined as an integer multiplied by itself to generate a perfect square, which is a positive integer. Perfect squares are just numbers that are the products of integers multiplied by themselves.

When an expression can be seen as the difference of two perfect squares, i.e. a² -b², we can factor it as (a+b) (a-b).

The number is given in the question,

(-5)²

We have to determine the simplified value of the given number (-5)².

⇒ (-5)²

⇒ (-5)(-5)

⇒  5 × 5 × (-1) × (-1)

⇒ 25 × 1

⇒ 25

Thus, the required simplified value of the given number (-5)² would be 25.

Omar will buy at least 5 pounds of candy. To find this, divide his minimum spending ($40) by the cost per pound of candy ($8). The inequality solved for p is p \geq 5, meaning Omar can buy 5 or more pounds of candy.

To find out the possible number of pounds of candy Omar will buy, we can set up an inequality using the given information. We know the cost per pound of candy is $8, and Omar is going to spend at least $40 on candy. Therefore, the inequality representing the situation can be written as:

8  imes p \\(cost per pound \\ times number of pounds)\\ \geq 40 (Omar's minimum spending)

To solve for p, the number of pounds, we divide both sides of the inequality by 8:

p \geq \frac{40}{8} \Rightarrow p \geq 5

So, Omar will buy at least 5 pounds of candy. This means that the possible numbers of pounds he may buy are 5 or more.

[tex]y=4x+1[/tex]

Step-by-step explanation:

The line is shown in the attachment.

The slope of this line is given by: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The line passes through (0,1) and (1,5)

Plug in the points to get:

[tex]m=\frac{5-1}{1-0}=4[/tex]

The equation of this line is given by [tex]y=mx +b[/tex], where b=1 is the y-intercept.

From the graph the y-intercept is 1, because the line intersects the y-axis at (0,1).

Therefore the equation is [tex]y=4x+1[/tex]

First, distinguish the mathematical elements in the expression 12r²4. Multiply the numbers 12 and 4 to give 48, then substitute this value back in to obtain the simplified expression, 48r². The property of multiplication allows this reordering and regrouping without affecting the result.

To simplify the given expression, 12r²4, the first step involves distinguishing the mathematical elements present. In this case, we have multiplication of numbers and a variable. Technically, the expression is equivalent to 12*r^2*4, since there is multiplication between each element.

We proceed with multiplication, starting with the numerical value. In this case, multiply 12 and 4 to get 48. Substitute this resulting value into the expression, yielding 48r². The justification for this operation is the property of multiplication, which is associative and commutative. It allows us to change the order of the numbers being multiplied or group them differently without changing the result.

Answer:

26/100 which is simplified to 13/50

Step-by-step explanation:

you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50

The sum of 2/10 and 6/100 is 13/50.

To find the sum of 2/10 and 6/100, we'll first find a common denominator and then add the fractions together.

The common denominator for 10 and 100 is 100, as it is the smallest multiple that both denominators can evenly divide into.

Now, we'll rewrite both fractions with the common denominator of 100:

2/10 = (2/10) * (10/10) = 20/100

6/100 = 6/100

Now that both fractions have the same denominator, we can add them together:

20/100 + 6/100 = (20 + 6)/100 = 26/100

Now, we have the sum of the fractions as 26/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:

(26 ÷ 2) / (100 ÷ 2) = 13/50

The solution to the inequality is 1 < x ≤ 8.

The given inequality can be split into two components:

The difference of 2x and 5 is greater than -3: This can be written as:

2x - 5 > -3

To solve for x, we first add 5 to both sides of the inequality:

2x > 2

Then, we divide both sides by 2:

x > 1

This indicates that the values of x which satisfy this part of the inequality are greater than 1.

The difference of 2x and 5 is less than or equal to 11: This can be written as:

2x - 5 ≤ 11

Adding 5 to both sides:

2x ≤ 16

Dividing both sides by 2:

x ≤ 8

Therefore, the common range that satisfies both parts is 1 < x ≤ 8.

To find the area of the storage facility, calculate the area of each shape and add them together. The correct expression is 36x^2+24x.

To find the area of the storage facility, we need to find the area of each individual shape and add them together. Looking at the diagram, we can see that the storage facility is composed of two rectangles and one square. Let's calculate the area of each shape:

Area of first rectangle = length x width = 4x(4x+4) = 16x^2+16x

Area of second rectangle = length x width = 4x(4x+2) = 16x^2+8x

Area of square = side x side = (2x)^2 = 4x^2

To find the total area, we add the areas of the three shapes:

Total area = (16x^2+16x) + (16x^2+8x) + 4x^2 = 36x^2+24x

Therefore, the correct expression that represents the area of the storage facility is 36x^2+24x, which is option B.

Answer:

Step-by-step explanation:

The value of can be get in two way.

For the column G, the total value is given by 58%.

In the row of F and column of G, the value is 31%.

Hence, the value of y is (58 - 31) = 27%.

Again, In the row of E, the total value is given by 51%.

The E-th row and H-th column shows the value 24%.

Hence, the value of y is (51 - 24) = 27%.

Answer:

42 times.

Step-by-step explanation:

The number of total alphabet = 26 tiles

The number of vowels = 5

The number of consonant = 26 - 5 = 21

Sofia will randomly select 1 tile from the bag and without replacement select another tile from the bag.

The probability to select consonant at first time = 21/26

Total tiles after the first selection = 26 - 1 = 25

The probability to select vowels at second time = 5/25

The probability to select consonant and vowels = [tex]\frac{21}{26} *\frac{5}{25} =\frac{21}{130}[/tex]

Sofia will draw two tiles from the bag 260 times.

The prediction for the number of times Sofia will select a consonant tile and a vowel tile = [tex]\frac{21}{130} *260=42 \ times[/tex]
