The volume of Mya's lunchbox can be calculated by multiplying its length, width, and height. However, the dimensions were not provided in the question.

The volume of a three-dimensional object like Mya's lunchbox can be found by multiplying the object's length, width, and height together. If Mya's lunchbox is a rectangular prism, for instance, and we know its measurements, we can calculate its volume using the formula Volume = Length x Width x Height. However, the question didn't provide the necessary dimensions of the lunchbox. Therefore, you need to provide the dimensions of the lunchbox for me to be able to help you calculate its volume.

Final answer:

To simplify the expression sqrt(18) + sqrt(50), find the square roots of 18 and 50 individually and then add them together.

Explanation:

To simplify the expression sqrt(18) + sqrt(50), we need to find the square roots of 18 and 50 individually and then add them together. The square root of 18 is approximately 4.2426 and the square root of 50 is approximately 7.0711. Adding these two values gives us approximately 11.3137. Therefore, the simplified expression is sqrt(18) + sqrt(50) = 11.3137.

To reflect triangle A across the line y = 1, determine the corresponding points and apply symmetry properties. By understanding geometric transformations and symmetry, you can accurately visualize the new position of the triangle.

Reflecting triangle A in the line y = 1 involves transforming the triangle's position by flipping it over this horizontal line. This reflection will create a new image of the triangle across the line y = 1.

To reflect triangle A in y = 1, you need to locate the corresponding points across the line concerning their distance from the line itself. For instance, a point (x, y) would transform to (x, 2 - y) after reflection across y = 1.

Understanding symmetry properties and geometric transformations is crucial in reflecting shapes across lines, helping to visualize changes in position accurately.

Answer:

(-15,14)

Step-by-step explanation:

as the question states, d is a mid point. so, if there is a -12 difference in x, then you must apply that to d to create the opposite point. the same goes for y but its a +10 difference. when you apply it, d is (-15,14)

Answer: (-15,14)

Step-by-step explanation:

Answer:

We cannot answer this question because there isn't a line plot for us to drag the data onto.

Create a line plot with radii lengths on the x-axis and frequency on the y-axis, connecting plotted points accordingly.

First, organize the data into a list or table format, with the lengths of the radii listed in feet:

1/2, 1/2, 3/8, 3 1/6, 3 1/6, 3 1/6, 1/2, 3/8, 12, 7 1/6

Next, you'll create a number line representing the lengths of the radii. You'll mark each length on the number line and then plot points above each mark corresponding to the frequency of each length.

For example:

- If there are two radii with a length of 1/2 foot, you'll plot two points above the mark for 1/2 on the number line.

- If there are three radii with a length of 3/8 foot, you'll plot three points above the mark for 3/8 on the number line.

- Similarly, for other lengths, mark and plot points accordingly.

Once you've plotted all the points, you'll connect them to form a line plot. The x-axis will represent the lengths of the radii, and the y-axis will represent the frequency of each length.

Answer: C

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

Square both sides:

[tex](\sqrt{-5-2x})^2 =(\sqrt{-1-x} )^2[/tex]

The square root and the square will cancel to leave simply the argument within the square root:

-5 - 2x = -1 - x

Now simply isolate the variable x:

x = -5 + 1 = -4

Check to see if x = -4 will work:

[tex]\sqrt{-5-2*(-4)} =\sqrt{-1-(-4)}[/tex]

[tex]\sqrt{3} =\sqrt{3}[/tex]

This works, so we know that x = -4 is a solution.

Step-by-step explanation:

If all angles that are either adjacent or opposite are supplementary, all angles must be 90°

If at all times adjacent sides are 5 inches, all sides are equal.

Knowing this, it has to be a square because all angles would be 90° and all sides would be equal.

Supplementary angles are two angles that when added together equal 180 degrees, forming a straight line when placed beside each other.

Answer with Step-by-step explanation:

We are given that height of projectile after t seconds is given by

[tex]h(t)=96t-16t^2[/tex]

a.h(t)=144 ft

[tex]144=96t-16t^2[/tex]

[tex]16t^2-96t+144=0[/tex]

[tex]t^2-6t+9=0[/tex]

[tex]t^2-3t-3t+9=0[/tex]

[tex]t(t-3)-3(t-3)=0[/tex]

[tex](t-3)(t-3)=0[/tex]

t-3=0

t=3

After 3 s, the height of the project will be 144 feet in the air.

b.h(t)=0

[tex]96t-16t^2=0[/tex]

[tex]16t(6-t)=0[/tex]

Answer:

Number of bacteria at 11:53 for 53 min = [tex]2^{53}[/tex]   = 9.007199 × [tex]10^{15}[/tex]  

fraction that is full = [tex]2^{-7}[/tex]

Step-by-step explanation:

solution

Number of bacteria is express as here

Number of bacteria = [tex]2^t[/tex]    ............1

so

bacteria at 1 min , 2 min and 3 min are

Number of bacteria at 1 min = [tex]2^1[/tex] = 2

Number of bacteria at 3 min = [tex]2^2[/tex] = 4

Number of bacteria at 3 min = [tex]2^3[/tex]  = 8

and

as that Number of bacteria at 11:53 is for 53 min is

Number of bacteria at 11:53 for 53 min = [tex]2^{53}[/tex]   = 9.007199 × [tex]10^{15}[/tex]  

and

bottle is full at 12:00

so Number of bacteria at 12:00 for 60 min = [tex]2^{60}[/tex]  

so fraction that is full = [tex]\frac{2^{53}}{2^{60}}[/tex]

fraction that is full = [tex]2^{-7}[/tex]

A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

Number of bacteria present in bottle at 11:53  are [tex]2^{53}[/tex].

At that time, fraction [tex]2^{-7}[/tex] or 0.00781 of bottle is full.

Since, single bacterium is placed in a bottle at 11:00am. It grows and at 11:01 divides into two bacteria. These two bacteria each grow and at 11:02 divide into four bacteria. Which grow and at 11:03 divide into eight bacteria.

So, a sequence is obtained  1, 2, 4, 8, 16, 32, 64, .........

We can also write as,

At 11:00 am,    [tex]2^0[/tex] bacteria

At 11:01 am,    [tex]2^1[/tex] bacteria

At 11:02 am,   [tex]2^2[/tex]  bacteria

Similarly,  At 11:53 am, Number of bacteria present in bottle are [tex]2^{53}[/tex].

When the bottle will be full, that time number pf bacteria will be [tex]2^{60}[/tex].

S0, fraction of bottle is full at 11:53 is   [tex]2^{53} /2^{60} = 2^{-7} = 0.00781[/tex]
