Cia collected the most money

Jen collected the least money.

Step-by-step explanation:

Let Jen collected money = x

Mark collected money = 23x

while Cia collected money = 212 (23x)

So, we can observe that Cia and Mark collected more money than Jen as Jen money is multiplied by 23 to make Mark's money and Mark's money is multiplied by 212 to get Cia's Money.

So, Cia collected the most money

Jen collected the least money.

In the graph or a table you easily can see trends in the data, for example, parts where if x increases also does y, or things like that.

Of course you, with some mathematical knowledge, also can notice those things when you have the equation, so this is a thing that the 3 have in common.

Range:

You usually can see the whole range (all the possible y values) of your equation by looking at the graph or the data set. And obviously, if you have the equation you can easily find the range of it.

Option(B):  [tex]\(\dfrac{15}{108}\)[/tex]   is Correct Choice.

Explanation:

To find the probability that the next movie shown at Cinemania theater is an action movie, we can use the formula:

[tex]\[ \text{Probability} = \frac{\text{Number of action movies}}{\text{Total number of movies}} \][/tex]

Given that there were 15 action movies out of 108 total movies shown last year:

[tex]\[ \text{Probability} = \frac{15}{108} \][/tex]

So, the reasonable estimate of the probability that the next movie is an action movie is:

[tex]\[ \frac{15}{108} \][/tex]

Thus, the correct choice is:

(Choice B)  [tex]\(\dfrac{15}{108}\)[/tex]

Question:

The Cinemania theater showed 108 different movies last year. Of those, 15 movies were action movies.

Mark lives 5,000 feet away from school and walks at a steady rate of 250 feet per minute, so it takes him 20 minutes to walk to school.

Step-by-Step Explanation

Mark lives 5,000 feet from school and walks at a steady rate of 250 feet per minute. To calculate the time it takes for Mark to walk to school, we divide the total distance by his speed:

Time = Distance \/ Speed

Time = 5,000 feet \/ 250 feet per minute

Time = 20 minutes

Thus, Mark takes 20 minutes to walk to school from his home.

To find the length and width, we use the provided information and the formulas for area and length. After determining the width is 7 feet, we find the length is 42 feet. Using these dimensions, the rectangle's perimeter is 98 feet.

Given the length of the rectangle is six times its width, we can denote this as L = 6W. The area of a rectangle is given by the formula Area = Length x Width or A = LW. Substituting L = 6W into our area formula gives A = 6W^2. We're given that the area is 294 square feet, so we set our formula equal to this: 6W^2 = 294. Solving this gives W = 7 ft.

Now, we substitute W = 7 ft back into our length formula, L = 6W, giving L = 42 ft. The perimeter of a rectangle is given by the formula Perimeter = 2(Length + Width) or P = 2(L + W), therefore P = 2(42 ft + 7 ft) = 98 ft.

Answer:

Volume of wood chips in the pickup truck is  [tex]70[/tex] cubic units.

Step-by-step explanation:

Given that,

The pickup truck rectangular bed with an area of [tex]35[/tex] square feet.

Height of wood chips is [tex]2[/tex] feet.

From the question,

The shape formed by combination of rectangular bed and wood chips is a cuboid shape.

So, Volume of cuboid is [tex]= l\times b\times h[/tex] cubic unit.

Then, Volume of wood chips [tex]=Area\times height[/tex]

                                                 [tex]= 35 \times 2=70[/tex] cubic units.

Therefore, Volume of wood chips in the pickup truck is  [tex]70[/tex] cubic units.

The volume of wood chips in Ernesto's pickup truck is calculated by multiplying the bed's area of 35 square feet by the height of 2 feet, resulting in a total volume of 70 cubic feet.

To determine the volume of wood chips that Ernesto's pickup truck can carry, we start with the given area of the rectangular bed, which is 35 square feet. Knowing the bed area and that Ernesto fills the bed to a height of 2 feet, we can calculate the volume by multiplying the area by the height.

Here is a step-by-step explanation:

Identify the area of the truck's bed: 35 square feet.

Identify the height to which the wood chips are filled: 2 feet.

Calculate the volume by multiplying the area by the height: Volume = area * height = 35 ft² * 2 ft.

Therefore, the volume of wood chips that the truck can carry is 70 cubic feet.

Step-by-step explanation:

As we have to use the number 0-6 once to make 2 equivalent ratios.

so lets solve the problem.

Determining first equivalent ratio

as

and

so

Therefore, first equivalent ratio

[tex]\:\frac{5}{32}=\frac{10}{64}[/tex]

Determining second equivalent ratio

[tex]\frac{13}{65}=\frac{4}{20}[/tex]

as

[tex]\frac{13}{65}=\frac{1}{5}[/tex]

and

[tex]\frac{4}{20}=\frac{1}{5}[/tex]

Therefore, second equivalent ratio

[tex]\frac{13}{65}=\frac{4}{20}[/tex]

Both can be simplified to 1:2.

To create two equivalent ratios using the numbers 0-6 once, we first need to understand that a ratio compares two quantities and equivalent ratios can be simplified or expanded from one another by the same factor. Here, we select the numbers carefully to form such ratios.

Let's use the numbers 2, 3, 4, and 6. The ratio of 2:4 is equivalent to 3:6 because when both sides of the first ratio are multiplied by 2, the result is the second ratio. Therefore, the ratios 2:4 and 3:6 are equivalent because they express the same relationship between numbers, as both can be simplified to the ratio of 1:2.

Final answer:

When solving a system by elimination, the variable eliminated is the one with coefficients that add up to zero when equations are combined.

Explanation:

When solving the following system by elimination, which variable would be eliminated after adding the 2 equations together?

When adding the two equations together in a system, the variable that will be eliminated will be the one that has coefficients with additive inverse values. For example, if one equation has x and the other has -x, adding them would result in the elimination of the x variable.

After adding the two equations together, look for a pair of variables that will cancel each other out, resulting in the elimination of one variable.

Fractions

The values are  [tex]\frac{1}{4} , \frac{1}{8} , \frac{1}{81}[/tex]

Step-by-step explanation:

As we know the fractions whose numerators are 1 can be represented in exponents and vice versa provided that the power of the exponent is (-1) ,

like 1/a = a^(-1)  

[tex]\frac{1}{a}[/tex]  = [tex]a^{-1}[/tex]

so accordingly

a)

   4^(-1) or [tex]4^{-1}[/tex] can be represented exponentially as ¼ .

⇒   [tex]\frac{1}{4}[/tex]

Part b)

2^(-3)  or [tex]2^{-3}[/tex]

We can simplify the exponent so that the power should be equal to -1.

And, so [tex]2^{3}[/tex] = 8

So we can write the above the expression as 8^(-1)  or [tex]8^{-1}[/tex]

So the fraction corresponding to it is [tex]\frac{1}{8}[/tex].

⇒ [tex]\frac{1}{8}[/tex]

Part c)

3^(-4) now we  can simplify the exponent so that the power of the exponent is -1.

And thus , (3 ^4)^(-1) = 81^(-1)  = [tex]\frac{1}{81}[/tex]

So the fraction obtained is [tex]\frac{1}{81}[/tex].

⇒ [tex]\frac{1}{81}[/tex]

The values are  [tex]\frac{1}{4} , \frac{1}{8} , \frac{1}{81}[/tex]

Answer:

choice A.  line BC = line EF

Step-by-step explanation:

we need the sides  BC = EF

This is the side between the congruent angles.

For the congruence of the triangles, AB ≅ DE, BC ≅ EF, or CA ≅ FD should be congruent. Then the correct option is A.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If the two triangles are congruent, then the ratio of the corresponding sides will be one.

If any two sides and one angle of the triangles are congruent, then the triangles are congruent.

Or if any two angles and one side of the triangles are congruent, then the triangles are congruent.

In the figure, the two angle of the triangle are congruent.

For SAS postulate, then the sides will be

AB ≅ DE

BC ≅ EF

CA ≅ FD

Then the correct option is A.

Step-by-step explanation:

Answer: You need to wait at least 6.4 hours to eat the ribs.

t ≥ 6.4 hours.

Step-by-step explanation:

The initial temperature is 40°F, and it increases by 25% each hour.

This means that during hour 0 the temperature is 40° F

after the first hour, at h = 1h we have an increase of 25%, this means that the new temperature is:

T = 40° F + 0.25*40° F = 1.25*40° F

after another hour we have another increase of 25%, the temperature now is:

T = (1.25*40° F) + 0.25*(1.25*40° F) = (40° F)*(1.25)^2

Now, we can model the temperature at the hour h as:

T(h) = (40°f)*1.25^h

now we want to find the number of hours needed to get the temperature equal to 165°F. which is the minimum temperature that the ribs need to reach in order to be safe to eaten.

So we have:

(40°f)*1.25^h = 165° F

1.25^h = 165/40 = 4.125

h = ln(4.125)/ln(1.25)  = 6.4 hours.

then the inequality is:

t ≥ 6.4 hours.

Answer:

40 × 1.25 ^ t greater or equal to ( >) 165
