Answer:

504

Step-by-step explanation:

To find the average of a series of numbers one must add them all then divide by the amount of numbers.

So....

516+497+501+528+476= 2,518

then...

2,518/5 = 503.6

6> 5 so you would round UP

Final answer:

The problem involves finding the values of x and y in a parallelogram, using given segment lengths. Without an additional equation, we can only express one variable in terms of the other, resulting in the equation 4 = 3x + 2y.

Explanation:

The question is asking us to find the values of x and y in a parallelogram DEFG, where we know the lengths of some segments inside the parallelogram, specifically DH, HF, GH, and HE. As properties of a parallelogram dictate that opposite sides are equal in length, and segments DH and HF form one side, while segments GH and HE form the opposite side, we conclude that DH + HF must equal GH + HE.

Setting up the equation (x + 2) + (2y) = (4x - 3) + (4y + 1), we combine like terms, which gives us x + 2y + 2 = 4x + 4y - 2. Upon further simplification, by subtracting x and 2y from both sides, we get 4 = 3x + 2y. This equation allows us to express one variable in terms of the other.

Finding a specific value for x and y would require additional information, such as another equation involving x and y to solve this system of equations. Without this, we are limited to only expressing one variable in terms of the other.

Answer:

1) 15/32

2) 2

Step-by-step explanation:

1) 3 /8  / 5/4

= 3 · 5 /8 · 4

= 15 /32

2) 4/5 * 2 1/2

First solve --> 2 1/2 = 2 · 2 + 1 /2

= 5 /2

Then solve: 4 /5  * 5 /2

= 4 · 5 /5 · 2

= 20 /10

= 2 · 10 /1 · 10

= 2

Answer:

Here's what I get.

Step-by-step explanation:

You have two conditions.

1. The club must raise at least $500, and that comes from the sale of lemonade and water.

Let c = cans of lemonade

and b = bottles of water

Then the first condition is

(1) 2c + 1.50b ≥ 500

2. The club can accept a maximum of 360 cans and bottles

Your second condition is

(2) c + b ≤ 360

Your system of inequalities is

[tex]\left[ \begin{array}{rcl}2c + 1.50b & \geq & 500\\c+b & \leq&360\\\end{array}\right][/tex]

Answer:

4 ounces of flour will make 1 cake.

Step-by-step explanation:

16 ounces = 1 pound

16 ounces divided by 4 cakes = 4 ounces for 1 cake

Jesse needs ⅔ pound or 0.125 pounds (2 ounces) of flour to make one cake, calculated by dividing the half-pound bag of flour by the number of cakes it can produce (4 cakes).

Jesse is baking cakes for a bake sale and needs to know how much flour is needed for one cake.

From the information provided, we know that a ½ pound bag of flour is enough to make 4 cakes.

To determine how much flour is needed for one cake, we use a simple division.

To find the amount of flour per cake, we divide the total amount of flour by the number of cakes that can be made from it. That gives us:

½ pound flour ÷ 4 cakes = ⅔ pound flour per cake.

Therefore, Jesse needs ⅔ pound (which is 0.125 pounds or 2 ounces) of flour to make one cake.

A = 28 in²

Step-by-step explanation:

Equation for the area of a parallelogram: A = b * h

Plug in: A = 7 in * 4 in

Solve: A = 28 in²

Answer:

its 28

Step-by-step explanation:

The correct answer is (D) because 3 multiple 1/3, the 3 go with 3 and we get the 1. And 9 multiple 1/3, the 9 go with 3 and we will go 3 multiple 1 and we will get 3.

- "Let's see how many packs of each item we can make and what's left over. That's the remainder.

287 = 6(287/6) = 6(47) + 5

143 = 3(143/3) = 3(47) + 2

341 = 7(341/7) = 7(48) + 5

So on that 48th pack we have 5 people markers so need 1 more and 2 dice, so we need one more. We have enough teleport markers for the 48th pack.

Choice A."

Answer:

Step-by-step explanation:

f⁻¹(x) is the inverse of f(x).

y = 4x − 9.  To find the inverse, switch x and y and solve for y.

x = 4y − 9

x + 9 = 4y

y = (x + 9) / 4

So the inverse function is:

f⁻¹(x) = (x + 9) / 4

ANSWER

[tex]{f}^{ - 1}(x) = \frac{x + 9}{4} [/tex]

EXPLANATION

The given function is

f(x)=4x-9

Let

y=4x-9

Interchange x and y.

x=4y-9

Add 9 to both sides,

x+9=4y

Divide both sides by 4

[tex] \frac{x + 9}{4} = y[/tex]

[tex]y = \frac{x + 9}{4} [/tex]

Therefore,

[tex] {f}^{ - 1}(x) = \frac{x + 9}{4} [/tex]

Step-by-step explanation:

Probability that the next customer to enter Jeremy's Pet Store has exactly 3 pets is 0.23.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that a dot plot shows how many pets each customer owned before entering Jeremy's Pet Store today.

Based on this data we need to find the reasonable estimate of the probability that the next customer to enter Jeremy's Pet Store has exactly 3 pets.

The total number of customer enter  Jeremy's Pet Store is 13.

Probability that the next customer to enter Jeremy's Pet Store has exactly 3 pets= 3/13

=0.23

Hence, Probability that the next customer to enter Jeremy's Pet Store has exactly 3 pets is 0.23.

Answer:

The correct answer is option C.   16√2

Step-by-step explanation:

Points to remember

If the angles of a right angled triangle are 45°, 45° and 90° then the sides of the triangles are in the ratio 1 : 1: √2

To find the length of each leg of triangle

From the figure we can see that a right angled triangle with angles 45°, 45°, 90° and hypotenuse = 32

Therefore the sides are in the ratio 1 : 1 :√2

Leg1 : Leg2 : hypotenuse = 1 : 1 : √2 = x : x : 32

Therefore x = 32/√2 = 16√2

So the correct answer is option C.   16√2

The cube of a number (n) divided by two can be mathematically represented as n³/2.

The cube of a number is achieved when you raise that number to the power of 3. If we have a number, let's denote it as 'n', and we cube it, and we get n³. Now, if you are to divide the cube of a number by two, the formula would be n³/2. For example, if n = 2, the cube of 2 is 8, divided by two equals 4.

The cube of a number divided by two means that you take a number raise it to the power of 3, and then divide the result by 2. For example, if the number is 4, the cube of 4 is 4 × 4 × 4 = 64. Dividing 64 by 2 gives you a result of 32.

To find the value of 'a' for which the line x = a splits the region into two equal areas, integrate the curve starting from -sqrt(a+1) to sqrt(a+1) and set it equal to the area of the region between the curve and the y-axis.

This question pertains to the concept of finding the area under curves in Calculus. To solve this problem, we need to set up an equation that represents the given situation and solve for 'a'. The line 'x = a' splits the region into two equal areas, meaning the area on the right of the line is equal to the area on the left of the line.

Starting from the x-axis, the curve 'x = y^2 - 1' intersects the line at y = sqrt(a+1) and y = -sqrt(a+1). Thus, we want the integral from -sqrt(a+1) to sqrt(a+1) of the curve to be equal to the area of the region between the curve and the y-axis. Formulate and solve the intergral problem to get the desired value of 'a'.

Additionally, this problem might involve the use of numerical methods like the Simpson's rule or midpoint rule to get an accurate result.

Step-by-step explanation:

Given

x² + x - 6 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)

The factors are + 3 and - 2, since

3 × - 2 = - 6 and 3 - 2 = + 1, hence

(x + 3)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 2 = 0 ⇒ x = 2

To find out how long it would take Petra to jog 13 miles at the same rate, we can set up a proportion and solve for the unknown variable. The answer is approximately 156 minutes.

To find out how long it would take Petra to jog 13 miles at the same rate, we can set up a proportion using the given information. Since Petra jogs 2 miles in 24 minutes, the rate at which she jogs is 2 miles / 24 minutes. We can use this rate to find out the time it would take her to jog 13 miles.

Set up the proportion: 2 miles / 24 minutes = 13 miles / x minutes. Cross multiply and solve for x to find the answer.

2 miles / 24 minutes = 13 miles / x minutes
2x = 24 × 13
2x = 312
x = 156

So, it would take Petra approximately 156 minutes to jog 13 miles at the same rate.
