If the number of sodas sold was three times the number of hot dogs sold then the number of sodas sold is 78 and the number of hot dogs sold is 26.
What is equation?Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.
How to form equation?The total number of hot dogs and sodas sold is 104 and the number of sodas sold was 3 times the number of hot dogs sold.
We have to form an equation first.
let the number of hot dogs sold be x.
Number of sodas will be 3x.
According to question :
x+3x=104
4x=104
x=26
Put the value of x in 3x to get the number of sodas sold.
=3x
=3*26
=78
Hence If the number of sodas sold was three times the number of hot dogs sold then the number of sodas sold is 78 and the number of hot dogs sold is 26.

\(2 ^{ \frac{1}{2} } = 2 ^{1 \times \frac{1}{2} } = \sqrt{2} \\ {2}^{ \frac{2}{3} } = 2 ^{2 \times \frac{1}{3} } = \sqrt[3]{2 ^{2} } \\ 3 ^{ \frac{3}{2} } = {3}^{3 \times \frac{1}{2} } = \sqrt[]{ {3}^{3} } \\ {3}^{ \frac{1}{3} } = 3 ^{1 \times \frac{1}{3} } = \sqrt[3]{3} \)
Step-by-step explanation:

A bakery sold 76 mocha cupcakes in a day, which was 95% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
The total cupcakes the bakery sell that day is 80
How many total cupcakes did the bakery sell that day?From the question, we have the following parameters that can be used in our computation:
Number of sales = 76
Proportion = 95%
This implies that
Number of sales = Proportion * Total number of cupcakes
Substitute the known values in the above equation, so, we have the following representation
76 = 95% * Total number of cupcakes
Divide both sides by 95%
Total number of cupcakes = 80

Last week, a chocolate shop sold 9 ounces of white chocolate. It sold 9 9/10 times as much milk chocolate as white chocolate. How many ounces of milk chocolate did the shop sell?
please answer asap
Solving the Question
We're given:
9 ounces of white chocolate sold\(9\dfrac{9}{10}\) times as much milk chocolate as white chocolate soldIf the shop sold " \(9\dfrac{9}{10}\) times as much milk chocolate as white chocolate", we must multiply \(9\dfrac{9}{10}\) by the amount of white chocolate sold to find the amount of milk chocolate sold.
Multiply \(9\dfrac{9}{10}\) by 9 ounces:
\(9\dfrac{9}{10}\times9\)
Convert the fraction into an improper fraction:
\(=\dfrac{99}{10}\times9\)
Multiply:
\(=\dfrac{891}{10}\)
AnswerThe shop sold \(\dfrac{891}{10}\) ounces of milk chocolate.

The error is that there is no proportional relationship between the ratios which is corrected and can be described as a linear relationship with the help of the equation y = m + 1.
What is the proportional relationship?Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportional relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.So, the ratios we have:
1:2 and 2:3.Then, performing:
1/2 = 0.52/3 = 0.67Hence, ratios of 1:2 and 2:3 are not equal.
Therefore, the error is that the relationship between the given ratios is not proportional.
As can be seen, each ratio has a difference of 1, that is:
2 - 1 = 13 - 2 = 1Therefore, when one variable changes by 1, the other variable only changes by a constant value (y = x = c).
It can therefore be described as a linear relationship, and the constant is 1.The equation has the following form:
y = x + 1Where y stands for the water solution and x for the vinegar component.
Therefore, the error is that there is no proportional relationship between the ratios which is corrected and can be described as a linear relationship with the help of the equation y = m + 1.

What is the slope of the line shown in the graph?
A 3/2
B) 2/3
C) -3/4
D) -2/3
Answer:
D.
Step-by-step explanation:
y-intercept is (0, 3)
x-intercept is (4.5, 0)
formula to find the slope from two points is
\(slope = m = \frac{y2 - y1}{x2 - x1} = \frac{y1 - y2}{x1 - x2} \\ \)
then the slope of the line that crosses (0, 3) & (4.5, 0) is
\(m = \frac{3 - 0}{0 - 4.5} = \frac{3}{ - 4.5} = - \frac{3}{ \frac{9}{2} } = - \frac{2}{3} \)
El 40% de un numero es igual a 20
The value of 40 percent of 20 is 8.
What is a percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
In this case, the 40 percent of 20 will be:
= 40% × 20
= 40/100 × 20
= 0.4 × 20

whats the product of (-3/4) and (3/4)
The product of (-3/4) and (3/4) can be found by multiplying the numerators and the denominators separately. The fraction -9/16 represents the product of (-3/4) and (3/4) in its simplest form
The step-by-step solution for finding the product of (-3/4) and (3/4).
To multiply fractions, you multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom) separately. In this case, you have:
Numerators: -3 * 3 = -9
Denominators: 4 * 4 = 16
The numerator of the product is -9, and the denominator is 16.
The resulting numerator, -9, indicates that the product will have a negative value. This happens because one of the original fractions, (-3/4), is negative.
The resulting denominator, 16, is obtained by multiplying the original denominators, 4 and 4.
Putting it all together, the product of (-3/4) and (3/4) is -9/16. This means that when you multiply (-3/4) by (3/4), the result is a fraction with a numerator of -9 and a denominator of 16.
The fraction -9/16 represents the product of (-3/4) and (3/4) in its simplest form.

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is that snow Is falling steadily such that after 2 hours, 4 inches of snow has fallen.
In 2 hours → 4 inches of snow has fallen.
Then, in 1 hour → (4/2) → 2 inches of snow has fallen.

Find the total value of the prize: $
If the state can earn 5% interest on investments, how much money will they need to put into an account
now to cover the weekly prize payments?
Reminder: There are 52 weeks in a year.
The total value of the prize is $936,000.
The state will need to invest $591,498.96 now at a 5% interest rate to cover the weekly prize payments for 20 years.
What is the total value of the prize?The total value of the prize is calculated by multiplying the annual payment by the number of years and is equal to:
= $900/week x 52 weeks/year x 20 years
= $936,000.
How much money is needed to put into the account?We need to use the present value formula which is: PV = PMT x [1 - (1 + r)^-n] / r
Plugging in the values:
PV = $900 x [1 - (1 + 0.00096154)^-1,040] / 0.00096154
