Answer: 35 days, on engenuity

Step-by-step explanation:

The solution is, 75% of students read less than 35 pages.

A stem-and-leaf display or stem-and-leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution.

here, we have,

Stem and leaf plots are a way of organizing data; the stem shows the first digit and then the leaves show the second digit.

We have that the number of observations (which is equal to the number of leaves) is 23.

23*75%=17.75.

Let us see what the 18th student studied for; 35 hours is the result.

Since the data in a stem leaf plot is in ascending order, we just need to notice the 18th leaf, reading from left to right.

33 pages would be wrong since only 17/23=74% of students read less than that.

Hence, 75% of students read less than 35 pages.

Answer:

C.Segment AC=Segment A''C'' over 2

Step-by-step explanation:

We are given that

Dilation scale factor=2

A=(-3,3)

B=(1,-3)

C=(-3,-3)

We know that in dilation the size of figure change  

Ratio of length of new segment to the length of segment of original figure=Scale factor

[tex]\frac{A''C''}{AC}=2[/tex]

[tex]AC=\frac{A''C"}{2}[/tex]

Option C is true.

C.Segment AC=Segment A''C'' over 2

The correct equation that explains the relationship between segment AC and segment A''C'' is: "segment A''C'' = segment AC over 2."

This equation reflects the effect of both the translation and dilation on the coordinates of the points A, C, A'', and C''.

The translation (x + 0, y + 2) shifts the original triangle ABC two units up along the y-axis.

The dilation by a scale factor of 2 from the origin doubles the distance between the points while keeping the same direction.

So, the length of segment A''C'' is half of the length of segment AC.

To elaborate, when you perform a translation, all points of the original triangle move in the same way by the same vector (in this case, 0 units horizontally and 2 units vertically).

After the translation, you apply the dilation from the origin, which scales the distances from the origin by a factor of 2.

So, the length of A''C'' is half of AC because the dilation reduces the distance by a factor of 2.

Hence, the equation "segment A''C'' = segment AC over 2" accurately represents this relationship.

Answer:

The system of equation to determine the quantity of nickels and quarters is simultaneous equation.

Nickels = 17

Quarters = 22

Step-by-step explanation:

Given

Let n represent number of nickels

Let q represent number of quarters

From line 1 of the question, we understand that

Total coins = 39

So, n + q = 39 because the made up of the nickels and the quarters

It's also stated that the total value of these 39 coins is $6.35.

First, it should be noted that

1 nickel is worth 0.05 and 1 quarter is worth 0.25, we can represent the total value of the coins with the following equation

0.05n + 0.25q = 6.35

At this point, we have two equation such can be solved simultaneously

n + q = 39 ------- (1)

0.05n + 0.25q = 6.35 ------- (2)

So, the system of equation to determine the quantity of nickels and quarters is simultaneous equation.

Solving further.....

Make q the subject of formula in equation (1)

q = 39 - n

Substitute 39 - n for q in equation 2

0.05n + 0.25q = 6.35 becomes

0.05n + 0.25(39 - n) = 6.35

0.05n + 9.75 - 0.25n = 6.35

Collect like terms

0.05n - 0.25n = 6.35 - 9.75

-0.2n = -3.4

Divide through by -0.2

-0.2n/-0.2 = -3.4/-0.2

n = 17

Recall that q = 39 - n

Substituton 17 for n in this equation

q = 39 - 17

q = 22

Hence, there are 17 nickels and 22 coins

The height of the parallelogram to the nearest tenth is; C: 4.8 units

Using Pythagoras theorem, we can find the smaller side of the parallelogram attached.

√(3² + 4²) = √25 = 5 units

The height of the parallelogram will be very close to this other side that measures 5 units.

Thus, the option that is closest to 5 units is 4.8 units and that is the height of the parallelogram.

The approximate corresponding height of the parallelogram is 4.8 units.

Option C is the correct answer.

Parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

The area of a parallelogram is equal to the product of its base and height. Therefore, we can find the height of parallelogram ABCD by dividing its area by the length of its base.

The area of parallelogram ABCD is equal to the area of triangle ABD, which has the same base as parallelogram ABCD and the same height as parallelogram ABCD.

Therefore, we can find the area of triangle ABD by dividing the area of parallelogram ABCD by 2.

Let h be the height of the parallelogram ABCD.

Area of triangle ABD

= (1/2) x base x height

= (1/2) x 8.6 units x h

Area of parallelogram ABCD

= base x height

= 8.6 units x h

Dividing the area of parallelogram ABCD by 2.

Area of triangle ABD

= (1/2) x 8.6 units x h

= 4.3 units x h

We know that the area of the parallelogram is greater than the area of the triangle because the parallelogram contains the triangle.

Therefore, the height of the parallelogram must be greater than the height of the triangle.

Let's say that the height of the parallelogram is approximately 4.8 units. Then, the area of the triangle is approximately:

Area of triangle ABD

= (1/2) x 8.6 units x 4.8 units

= 20.64 square units

Now,

Area of parallelogram ABCD.

= 8.6 units x 4.8 units

= 41.28 square units

This area corresponds to a height of approximately 4.8 units.

Therefore,

The approximate corresponding height of the parallelogram is 4.8 units.

Answer:

42 kg.m/s.

Step-by-step explanation:

Just add them:

= 22 + 20 = 42 kg. m/s.

The combined momentum of Object A with +20 kg.m/s and Object B with +22 kg.m/s is +42 kg.m/s, as both are moving in the same direction and there is no need to account for direction beyond the sign.

To determine the combined momentum of two objects, we simply need to add their individual momentums together, provided that they are moving in the same direction or dimension. In this case, Object B has a momentum of +22 kg.m/s and Object A has a momentum of +20 kg.m/s. Since both momentums are positive, they are both in the same direction (presumably the +x-direction). The combined momentum is the sum of the two:

Combined momentum = Momentum of Object A + Momentum of Object B

Combined momentum = +20 kg.m/s + +22 kg.m/s = +42 kg.m/s

The combined momentum of the two objects is +42 kg.m/s.

Step-by-step explanation:

1) Add -11 plus 19 which should give you 8.

2) Check your answer by subtracting 8 - 19 = -11

Heya there!

Let us learn that we want that variable to be by itself.

To get the variable (b) by itself we need to do some work.

Solving for B:

As we need to get B by itself, we beed to remove the "-19".

To do that, we have to +19 since the -19 is a negative.

This allows us to have B by itself.

b - 19 = -11

   +19    +19 to both sides ; whatever action we do to one side we do to the other.

Now, the equation should look like b = 8

We got b = 8 from the adding +19 to both sides. -11 + 19 = 8

Therefore, we are left with b = 8.

Answer:

7.9982

Step-by-step explanation:

-The function for an earthquake's magnitude is given by  R = 0.67log(0.37E) + 1.46

-E is energy in kwh.

#For 15,500,000,000 kilowatt hours the magnitude would be:

[tex]R = 0.67\ log(0.37E) + 1.46,\ \ E=15,500,000,000 \ kwh\\\\\therefore R=0.67 \ log(0.37\times 15,500,000,000)+1.46\\\\\\=7.9982[/tex]

Hence, the earthquakes magnitude is 7.9982

Final answer:

Calculate the earthquake's magnitude using the given energy value on the Richter scale.The earthquake's magnitude is approximately 7.99 on the Richter scale.

Explanation:

Richter Scale Magnitude Calculation:
Given R = 0.67log(0.37E) + 1.46, with E = 15,500,000,000 kWh, substitute E into the formula and solve for R:
R = 0.67log(0.37 * 15,500,000,000) + 1.46
R = 0.67log(5,735,000,000) + 1.46
R = 0.67 * 9.7581 + 1.46
R = 6.53 + 1.46
R = 7.99
The earthquake's magnitude is approximately 7.99 on the Richter scale.
