Answer: 40%

Step-by-step explanation: To find what percentage of members voted for Hans simply multiply 32 by 100.

32 x 100 = 3200.

Then, divide that number, or 3200 by 80.

3200/80 = 40.

So, 40, or 40% of members voted for Hans.:)

Answer

Pretty sure he can make 15 dozens. Which means he can make 180 cookies.

Step-by-step explanation:

First, you would need to find how many times 2 1/4 cups can go into 33 3/4 cups. This would let you know how many dozens he can make. You would get an answer of 15 dozens. Then, you would multiply 15 times 12. You would multiply by 12 because a dozen is 12. You would then get an answer of 180. This means that he can make 180 cookies.

Hope I helped! :) Sorry if it's wrong :(

Answer:

63÷4=$15.75(each sibling gave which made it up to $63)

63-40=$23(amount added together-amount paid)

$23÷4=$5.75(each sibling got back)

63-5.75x

if each contributed $18:

18×4=$72(each contribute 18 dollars so multiply by 4 because 4 siblings)

72-40=32(minus 40 from amount they contributed)

32÷4=$8(divide by 4 to see what each sibling got)

Each sibling got back $8

Answer:Simplifying

(5x + -6)(5x + -3) = 0

Reorder the terms:

(-6 + 5x)(5x + -3) = 0

Reorder the terms:

(-6 + 5x)(-3 + 5x) = 0

Multiply (-6 + 5x) * (-3 + 5x)

(-6(-3 + 5x) + 5x * (-3 + 5x)) = 0

((-3 * -6 + 5x * -6) + 5x * (-3 + 5x)) = 0

((18 + -30x) + 5x * (-3 + 5x)) = 0

(18 + -30x + (-3 * 5x + 5x * 5x)) = 0

(18 + -30x + (-15x + 25x2)) = 0

Combine like terms: -30x + -15x = -45x

(18 + -45x + 25x2) = 0

Solving

18 + -45x + 25x2 = 0

Solving for variable 'x'.

Factor a trinomial.

(3 + -5x)(6 + -5x) = 0

Subproblem 1

Set the factor '(3 + -5x)' equal to zero and attempt to solve:

Simplifying

3 + -5x = 0

Solving

3 + -5x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + -5x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + -5x = 0 + -3

-5x = 0 + -3

Combine like terms: 0 + -3 = -3

-5x = -3

Divide each side by '-5'.

x = 0.6

Simplifying

x = 0.6

Subproblem 2

Set the factor '(6 + -5x)' equal to zero and attempt to solve:

Simplifying

6 + -5x = 0

Solving

6 + -5x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + -5x = 0 + -6

Combine like terms: 6 + -6 = 0

0 + -5x = 0 + -6

-5x = 0 + -6

Combine like terms: 0 + -6 = -6

-5x = -6

Divide each side by '-5'.

x = 1.2

Simplifying

x = 1.2

Solution

x = {0.6, 1.2}

Answer:

5x/3+6

Step-by-step explanation:

Answer:

Internal angle = [tex]160^\circ[/tex]

Number of sides = 18

Step-by-step explanation:

Given that:

We have a regular polygon with number of sides unknown.

Measure of an exterior angle of the polygon = [tex]20^\circ[/tex]

To find:

Measure of an interior angle and the number of sides of the polygon?

Solution:

Let us have a look at the relation of sum of external angles.

Sum of one internal angle and its corresponding external angle = [tex]180^\circ[/tex]

Internal angle + external angle = [tex]180^\circ[/tex]

Internal angle = [tex]180^\circ[/tex] - [tex]20^\circ[/tex] = [tex]160^\circ[/tex]

Sum of all the external of a regular polygon = [tex]360^\circ[/tex]

All the external angles will be equal because it is a regular polygon.

Let the number of sides = [tex]n[/tex]

Therefore,

[tex]n \times 20^\circ = 360^\circ\\\Rightarrow n = 18[/tex]

Therefore, the answers are:

Internal angle = [tex]160^\circ[/tex]

Number of sides = 18

Answer:

12/13

Step-by-step explanation:

According to SOH CAH TOA;

cos theta = adjacent/hyp = 5/13

adj = 5

hyp = 13

Get the opposite

opp = √13²-5²

opp = √169-25

opp = √144

opp = 12

Get sin theta

sin theta = opposite/hyp

sin theta = 12/13

Hence the value of sin theta is 12/13

Answer:

Step-by-step explanation:

given:

40, 40, 50, 50, 60, 80, 80, 80

There are 8 numbers in the data set. To split this data set down the middle, that is between 50 and 60:

40, 40, 50, 50 || 60, 80, 80, 80

So now to get the median you have to do the following/

(50+60)/2 which equals 55.

Median is 55.

Answer: You got 57 points out of 60.

Step-by-step explanation:

Step 1: Define

3x² + 10x = 8

Step 2: Find Zeros

The selling price of each of the remaining calculators should be $65 so that the merchant makes a profit of $150 in the entire operation.

The merchant bought a batch of 15 calculators at $40 each, so the total cost of the batch is:

Cost price = 15 calculators × $40/calculator

= $600

The merchant sold 5 calculators at a promotional price of $100 each.

So, the revenue from selling these 5 calculators is:

Revenue = 5 calculators × $100/calculator

= $500

Now, we need to calculate the profit made from the sale of these 5 calculators:

Profit = Revenue - Cost price

Profit = $500 - $600

= -$100 (Negative because the merchant incurred a loss on these 5 calculators)

The merchant wants to make a profit of $150 in the entire operation. So, adding the profit from selling the first 5 calculators:

Desired profit = $150

Current profit = -$100

Additional profit needed = Desired profit - Current profit

Additional profit needed = $150 - (-$100)

= $250

The merchant has 15 - 5 = 10 calculators left to sell.

We need to distribute the additional profit of $250 among the remaining 10 calculators:

Additional profit per calculator = Additional profit needed / Number of remaining calculators

Additional profit per calculator = $250 / 10 calculators

= $25

Now, let's calculate the selling price of each of the remaining calculators:

Selling price = Cost price + Additional profit per calculator

Selling price = $40 + $25 = $65

So, the selling price of each of the remaining calculators should be $65.
