if the price of a hamburger increased from $3.50 to $4.20 what is the percentage increase in price

Answers

Answer:

Percent increase: 20%

Step-by-step explanation:

1. 4.2-3.5  x 100=20%

     3.5

2. Percent increase: 20%

Final answer:

The percentage increase in the price of a hamburger from $3.50 to $4.20 is a 20% increase. This is calculated by dividing the increase in price by the original price and then multiplying by 100.

Explanation:

To calculate the percentage increase in the price of a hamburger that went from $3.50 to $4.20, we first find the absolute increase by subtracting the original price from the new price.

The absolute increase is $4.20 - $3.50 = $0.70.

To find the percentage increase, we then divide the absolute increase by the original price, which gives us $0.70 / $3.50 = 0.2.

Finally, to express this as a percentage, we multiply by 100, resulting in a 20% increase in the price of the hamburger.

Answers

Answer:

Step-by-step explanation:

The given equation is 3x - 5y = 20 ........ (1)

Now, putting x = 5, in equation (1) we get,

15 - 5y = 20

⇒ 5y = - 5

y = - 1

So, the ordered pair (5,-1) is a solution of the equation (1).

Now, putting y = 2, in equation (1) we get,

Find the equation of a circle with a center of(5, 7) where a point on the circle is (10, 19)

Answers

Answer:

(x - 5)² + (y - 7)² = 169

Step-by-step explanation:

The standard form of the equation of a circle is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (5, 7), thus

(x - 5)² + (y - 7)² = r²

The distance from the centre to a point on the circle is the radius

Calculate the radius using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (5, 7) and (x₂, y₂ ) = (10, 19)

r = [tex]\sqrt{(10-5)^2+(19-7)^2}[/tex]

  = [tex]\sqrt{5^2+12^2}[/tex]

  = [tex]\sqrt{25+144}[/tex] = [tex]\sqrt{169}[/tex] = 13, hence

(x - 5)² + (y - 7)² = 169 ← equation of circle

People leaving an ice cream store were asked to name their favorite flavor of ice cream. Fifty-one people said chocolate was their favorite flavor. If 68% of the people surveyed said chocolate, how many people were surveyed?

Answers

Final answer:

To find the total number of people surveyed, you divide the number of people who chose chocolate (51) by the percentage that represents (0.68), resulting in 75 people surveyed.

Explanation:

The question posed involves determining the total number of people surveyed based on the percentage who favored chocolate ice cream. Since 68% of the people surveyed stated that chocolate was their favorite flavor, and it is known that 51 people chose chocolate, we can set up a proportion to find the total number of people surveyed. The proportion to find the total number of respondents (let's call it x) is as follows:



0.68 x = 51



To solve for x, you would divide both sides of the equation by 0.68, which gives you:



x = 51 / 0.68



x = 75 people



Therefore, the total number of people surveyed was 75.

Answers

Final answer:

To find the length of one leg of an isosceles right triangle with a hypotenuse of 10 inches, we use the Pythagorean theorem, which gives us a leg length of 5√2, or approximately 7.071 inches. The correct answer choice is StartFraction 10 Over StartRoot 2 EndRoot EndFraction.

Explanation:

The student is asking about the length of one leg of an isosceles right triangle where the hypotenuse measures 10 inches long. To find the length of one leg of this triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the legs (a and b).

Since the triangle is isosceles, the lengths of the legs are equal, so we have: a = b. The theorem can be expressed as a² + b² = c², which simplifies to 2a² = c² because a = b. We know the hypotenuse (c) is 10 inches, so the equation is 2a² = 10².

Let's find a:

2a² = 10²

2a² = 100

a² = 50

a = √50

a = √(25×2)

a = √25 × √2

a = 5√2

Therefore, the length of one leg of the triangle is 5√2, which is approximately 7.071 inches. So, the correct answer is StartFraction 10 Over StartRoot 2 EndRoot EndFraction.

Nick, a caterer, is investing some money in equipment and employees to help grow his business. Recently he spent $47 on equipment and hired a server who makes $15 per hour. Nick is hoping to make up these expense at the next job that is scheduled, which pays a base of $54 in addition to $14 per hour that the server works. In theory, this event could pay enough to cancel out Nick's expenditures. How much would the job pay? How long would the job have to be?



The expenditures and pay would both be $_ if the job lasted for _ hours.

Answers

Let X = the number of hours the server works.

The equation for the amount Nick spends is 15x + 47

The next job pays 14x + 54

Set the equations to equal and solve for x:

15x + 47 = 14x +54

Subtract 14x from both sides:

X + 47 = 54

Subtract 47 from both sides:

X = 7

Now replace x with 7 in the second equation:

14x + 54 = 14(7) + 54 = 98 +54 = 152

The job would pay $152 and be 7 hours long.

Which property states that order of the addends does not affect the sum?

A. commutative property of addition

B. associative property of addition

C. reflexive property of addition

D. additive identity property

Answers

Option A

Commutative property of addition  states that order of the addends does not affect the sum

Solution:

The commutative property of addition tells us that it does not matter which number we add first , We will still get the same answer if we add them backwards

This property is represented as:

For two numbers a, b:

a + b = b + a

In case of three numbers a, b, c:

a + b + c = c + b + a = b + a + c

So no matter how the addends are placed, the result of the operation (sum) remains the same

For example:

When we are adding 4 and 5

4 + 5 = 9 or 5 + 4 = 9 both the ways the result remains same

Thus Commutative Property of Addition states that changing the order of addends does not change the sum

Answer:

Commutative property of addition

Step-by-step explanation:

According to the commutative property of addition, changing the order of the numbers we are adding, does not change the sum.

A truck can carry a maximum of 1350 ponds of weight .how many 250- pound of dirt can the truck hold

Answers

Answer:

5.4

Step-by-step explanation:

1350/250=5.4

Final answer:

A truck with a maximum capacity of 1350 pounds can carry 5 full 250-pound loads of dirt, as partial loads cannot be accommodated.

Explanation:

How many 250-pound loads of dirt can a truck carry?

To determine how many 250-pound loads of dirt a truck can carry if its maximum capacity is 1350 pounds, you need to divide the truck's maximum capacity by the weight of one load of dirt:

1350 pounds ÷ 250 pounds per load = 5.4 loads

Since the truck cannot carry a fraction of a load, it can carry a maximum of 5 full 250-pound loads of dirt before it reaches its weight limit.

what is the sum of a 7-term geometric series if the first term is -6, the last term is -24576, and the common ratio is 4?

Answers

Answer:

The sum of the first seven terms of this geometric series is - 32,766

Step-by-step explanation:

Let's find out the result of the sum of a 7-term geometric series, which first term is -6, the last term is -24576, and the common ratio is 4

1st term = - 6

2nd term = - 6 * 4 = - 24

3rd term = - 24 * 4 = - 96

4th term = - 96 * 4 = - 384

5th term = - 384 * 4 = - 1,536

6th term = - 1,536 * 4 = - 6,144

7th term = - 6,144 * 4 = - 24,576

Sum = - 24,576 - 6,144 - 1,536 - 384 - 96 - 24 - 6

Sum = - 32,766

We can summarize these operations of the geometric series, this way:

Sₙ= a₁ * (1 − rⁿ)/1 − r, where:

n = Number of terms of the series

a₁ = First term of the series

r = Common ratio

Replacing with the real values, we have:

S₇= -6 * (1 −4⁷)/1 - 4

S₇= -6 * (1 − 16,384)/ -3

S₇= -6 * ( − 16,383)/ -3

S₇= 98,298/ -3

S₇= - 32,766

The sum of the first seven terms of this geometric series is - 32,766

Step-by-step explanation:

I think like 4 x 3 + 8 x 2 = 28 is a counterexample, because 28 is not a multiple of 8.

Final answer:

Perl's conjecture that the sum of a multiple of 4 and a multiple of 8 must be a multiple of 8 is incorrect. In fact, the sum would definitely be a multiple of 4 but not necessarily a multiple of 8, since the sum of integers multiplied by 4 does not guarantee that it's a multiple of 8.

Explanation:

The subject of this question is Mathematics, specifically dealing with number theory and the properties of multiples and factorization. Perl's conjecture is that the sum of a multiple of 4 and a multiple of 8 must be a multiple of 8. We can examine this by understanding how multiples work.

A multiple of 4 can also be considered as 4n, where n is an integer. Similarly, a multiple of 8 is 8m, where m is integer. If we add both, we get 4n+8m. Now, as per distributive property of multiplication over addition, the expression becomes 4n+4(2m), which can be further simplified as 4(n+2m).

We can now see that the sum is actually 4 times the sum of some integer, so it must indeed be a multiple of 4. However, since it's not necessarily the case that 'n+2m' itself is a multiple of 2, we cannot say that the overall sum is guaranteed to be multiple of 8.

A student used the following table of values and stated that the function described by the tables was a linear function

Answers

The question is missing the table. So, it is attached below.

Answer:

The function is not linear. The student didn't evaluate the rate of change for the given points on the function.

Step-by-step explanation:

Given:

From the table, the set of points of the function are:

(-1, -5), (0, 0), (2,5), (3, 10), and (4, 15)

A function is said to be linear if the rate of change of the function is always a constant.

Rate of change for any two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here, the rate of change for the points (-1, -5) and (0, 0) is given as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{0-(-5)}{0-(-1)}\\\\m=\frac{5}{1}=5[/tex]

Now, the rate of change for the points (0, 0) and (2, 5) is given as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{5-0}{2-0}\\\\m=\frac{5}{2}=2.5[/tex]

Hence, we can observe that, the rate of change is different for the given points. Hence, it is not a linear function.

Therefore, the student didn't evaluate the rate of change for the given points on the function.

Final answer:

A function is linear if the difference between y-values is constant when the difference between the corresponding x-values is constant. This is known as a constant rate of change and can be identified in a table of values for an x-y relationship. However, without the actual table's values, it's impossible to confirm its linearity.

Explanation:

In mathematics, a function is said to be linear if its graph forms a straight line. When analyzing a table of values, a function is linear if the difference between y-values is constant when the difference between the corresponding x-values is also constant. This is often called a constant rate of change.

For example, let's say we have an x-y table: for every 1 unit increase in x, if y increases by 2 units consistently, then the function represented by that table is linear. It directly satisfies the general definition of a linear function, y = mx + b, where 'm' is the slope (rate of change) and 'b' is the y-intercept.

However, without the actual values from the student's table, it's impossible to confirm whether the function is indeed linear. Always remember to check for a constant rate of change when reasoning about linearity.

The sum of a number and six is multiplied by negative four. The result is eight.

What is the number?

Answers

Answer:

-8

Step-by-step explanation:

(-8+6) * -4

-2 * -4= 8

Final answer:

The unknown number is -8, found by setting up the equation -4(x + 6) = 8 and solving for x.

Explanation:

To solve the problem stated, we need to set up an equation based on the provided information. The statement 'the sum of a number and six is multiplied by negative four' can be written as an algebraic expression: -4(x + 6), where 'x' is the unknown number we are trying to find.

We are told that this expression equals eight, so the equation we need to solve is -4(x + 6) = 8.

To solve for x, first we simplify the equation:

-4x - 24 = 8

Then we add 24 to both sides:

-4x = 8 + 24

-4x = 32

Now we divide both sides by -4 to solve for x:

x = 32 ÷ -4

x = -8

Therefore, the number we are looking for is -8.

In the expression below, a is an integer.
12x² + ax - 20
If 3x + 4 is a factor of the expression above, what is
the value of a ?​

Answers

Answer:

Step-by-step explanation:

The required simplified value of the a is given as a = 31.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
for the expression
12x² + ax + 20 = 0   (because this expression has factors)
The above expression has a factor (3x + 4)
3x + 4 = 0
x = -4 / 3
above the value of x is one of the zeroes for the given expression, so when we put it in the given expression the expression terminates to zero,
so,
f(-4/3) = 0
12(-4/3)² + (-4/3)a + 20 = 0
12×16/9 - 4a/3 + 20 = 0
-4a/3 = -20 - 64 / 3
-4a/3 = [-60 - 64] / 3
-4a = -124
a = 31

Thus, the required simplified value of the a is given as a = 31.
