[tex]\frac{3x^2}{x^2-6x-7}[/tex]

Step-by-step explanation:

The first step is to find the multiplied out numerator and denominator, and then to simplify if possible. For the numerator, 3x*x=3x^2. For the denominator, (x+1)(x-7)=x^2-6x-7. This gives a final fraction of [tex]\frac{3x^2}{x^2-6x-7}[/tex]. Hope this helps!

Answer:

Trends:

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.

Answer:

The median, because the data distribution is skewed to the right

Step-by-step explanation:

If the longer part of the box is to the right (or above) the median, the data is said to be skewed right. If the longer part is to the left (or below) the median, the data is skewed left.  The data is skewed right.  The median would be a better estimate, because one or two numbers on the high end will cause the  numbers to be skewed to the right, and the mean to be high

Answer:

Last one:

The median, because the data distribution is skewed to the right

Step-by-step explanation:

Q1: 7.5

Q2: 8

Q3: 23

Q2 - Q1 = 8 - 7.5 = 0.5

Q3 - Q2 = 23 - 8 = 15

Since Q3 - Q2 > Q2 - Q1,

data is positively (right) skewed

Skeweness occurs because of outliers therefore mean is not a suitable option. Median will provide a better description of the centre

Answer:

2161 miles

Step-by-step explanation:

The formula for the circumference of a circle is \pi d, where d represents the diameter. Therefore, if you divide the circumference of the moon by pi, you will get the diameter. 6790/pi is about 2161 miles. Hope this helps!

Final answer:

The diameter of the Moon is approximately 2161 miles when rounded to the nearest mile.

Explanation:

The circumference of the Moon is given as about 6,790 miles. To find the diameter, we use the formula for the circumference of a circle, C = πd, where C is the circumference and d is the diameter.

To solve for the diameter, the formula is rearranged to d = C / π. Using 3.14159 as an approximation for π, we calculate the diameter.

d = 6790 miles / 3.14159 ≈ 2160.98 miles

So, the diameter of the Moon is approximately 2161 miles when rounded to the nearest mile.

Step-by-step explanation:

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.

Answer:

Rachel has to drive for 5.789 seconds

Step-by-step explanation:

The equation that represents Rachel's remaining distance is:

[tex]D=-38t+220[/tex]

When Rachel completely escaped from the explosion, she has no distance to cover.

Hence D=0.

[tex] - 38t + 220 = 0[/tex]

[tex] - 38t = - 220[/tex]

Divide both sides by -38 to get:

[tex]t = \frac{ - 220}{ - 38} [/tex]

[tex]t = 5.789[/tex]

Rachel will cover 220m in approximately 6 seconds.

The total distance she has to drive is 220m

Rachel has to drive for approximately 6 seconds to reach her destination before the building explodes.

The given equation represents the relationship between Rachel's remaining distance (D) in meters and the time elapsed (t) in seconds.

The equation is:

D = -38t + 220

To find how long the distance Rachel has to drive, we need to find the value of D when she reaches her destination, which means D = 0 (since the distance remaining will be zero when she reaches the destination).

0 = -38t + 220

Now, solve for t:

38t = 220

t = 220 / 38

t ≈ 5.79 seconds

So, Rachel has to drive for approximately 6 seconds to reach her destination before the building explodes.

The total distance she has to drive is 220m.

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.

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:

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.

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: 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

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]
