a. The number of cubical packets on the floor is 30.
b. the number of cubical packets in 10 layers is 300 layers.
Length of cubical packetSince the volume of each cube is 1 cm³ and the volume of a cube V = L³ where L = length of side,
So, L = ∛V = ∛1 cm³ = 1 cm
So, the sides of the cubes are 1 cm long
Volume of layerAlso, since the rectangular box is 5 cm long and 6 cm wide, to find the number of 1 cm³ cubical boxes that can be placed on the floor, we find the volume of that layer which is V = 5 cm × 6 cm × 1 cm = 30 cm³
Number of cubical packets on the floorThe number of cubical packets on the floor is 30.
So, the number of cubical packets required, n = volume of layer/volume of cubical packet
= 30 cm³/1 cm³
= 30
The number of cubical packets on the floor is 30.
b. Number of cubical packets in 10 layersThe number of cubical packets in 10 layers is 300 layers.
If there are 10 layers, then the number of packets on the layers, N = number of layer × number of packets/layer
= 10 × 30
= 300 layers.
So, the number of cubical packets in 10 layers is 300 layers.

Max is mountain hiking at a constant rate. This equation y = 10x 30 can be used to represent this situation, where y is Max's elevation in meters and x is the number of hours Max has been hiking. Which statement best describes Max's elevation, given this equation?.
Answer:
D.) Max started at a height of 30 meters and is ascending at 10 meters per hour.
Step-by-step explanation:
This equation y = 10x + 30 can be used to represent this situation, where y is Max's elevation in meters and x is the number of hours Max has been hiking
Max started at the height of 30 meters and is ascending at a rate of 10 meters per hour. Then the correct option is A.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The equation is y = 10x + 30.
Where y is Max's elevation in meters and x is the number of hours.
Max has been hiking.
From the equation, we can conclude.
Max is ascending at a rate of 10 meters per hour.
Max is at the height of 30 meters at the starting.
Thus, option A is correct.

Find the percentage increase if 60 increases to 99.
Solve for y 8x-7y=23 (fill all of the boxes)
Answer:
i think this is the correct answer
Step-by-step explanation:
Simplifying
8x + -7y = 23
Solving
8x + -7y = 23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
8x + -7y + 7y = 23 + 7y
Combine like terms: -7y + 7y = 0
8x + 0 = 23 + 7y
8x = 23 + 7y
Divide each side by '8'.
x = 2.875 + 0.875y
Simplifying
x = 2.875 + 0.875y
Fill in the table using this function rule.

Answer:
10.3 cm
Step-by-step explanation:
There are a few ways to do this.
1)Using the law of cosines, you have ...
b² = a² +c² -2ac·cos(B)
b² = 11² +11² -2(11)(11)·cos(56°) = 106.67
b = √106.675 ≈ 10.3
AC = 10.3 cm
__
2)Using trig functions. When you draw an altitude in this isosceles triangle from B to AC, it divides AC in half, and it divides angle B in half. The sine relation can help here:
Sin = Opposite/Adjacent
sin(56°/2) = (AC/2)/(11 cm)
AC = (22 cm)sin(28°) ≈ 10.3 cm
__
3)Using a triangle solver, you can find the value of AC to be about 10.3 cm. Triangle solvers are available as apps and on the web. Your graphing calculator may have one. See attached for the results from a nice solver available on the web. Units are cm.
The balcony of an apartment is 4 feet wide by 7 feet long.

Enter your answer in the box. The actual width of the kitchen is feet.
For an apartment, the scale factor of the map is 1/60 and the kitchen's actual width of the is 12 ft wide.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
The balcony of an apartment is 4 feet wide by 7 feet long. On a scale drawing of the apartment, the balcony is 0. 8 inches wide by 1. 4 inches long.
The actual length of the balcony is 7 feet or 84 in (1 ft = 12in), and on scale the length of the balcony is 1.4 in. Thus, the scale factor is,
[tex]r=\dfrac{1.4}{84}\\r=\dfrac{1}{60}[/tex]
Thus, the scale factor is 1/60.
The length of the kitchen is 2.8 in on map. Let L is the actual length of the kitchen. Therefore,
[tex]r=\dfrac{2.8}{L}\\\dfrac{1}{60}=\dfrac{2.8}{L}\\L=168\rm in\\L=14\rm ft[/tex]
The width of the kitchen is 2.4 in on map. Let W is the actual width of the kitchen. Therefore,
[tex]r=\dfrac{2.4}{W}\\\dfrac{1}{60}=\dfrac{2.4}{W}\\W=144\rm in\\W=12\rm ft[/tex]
Thus, For an apartment, the scale factor of the map is 1/60 and the kitchen's actual width of the is 12 ft wide.

The angle of elevation of the sun is 39° from the ground. A business building downtown casts a shadow that is 89 m long. How tall is the building?
[tex]\tan 39 \textdegree = \displaystyle \frac{h}{89}\\\\89\tan 39 \textdegree = h\\\\h = 72[/tex]Answer:
72 m
Step-by-step explanation:
Hi there!
Using the given information, we can construct a diagram. Please see the attached image.
We need to solve for the height of the building, or the length of the side opposite the angle that measures 39°. Given the only other piece of information is the length of its adjacent side, which is 89 m, we can use the tangent ratio to solve for the height:
[tex]\tan \theta = \displaystyle \frac{opposite}{adjacent}[/tex]
Plug in the given values:
tan 39° = h/89
89 tan 39° = h
h = 72
Therefore, the height of the building is 72 m.
I hope this helps!
