or,v=((7×10)×18)
therefore, volume=1260cm^3.
Answer:
i think t is 1067.66
Step-by-step explanation:
volume of a square pyramid: V=a^2*h/3 since it is square all sides are equal
a=10, the height=18-7=11
V=10^2*11/3= 366.67 cm^3
the volume of the square pyramid= Area *height= length*width*height
V=10*10*7=700 cm^3

The law f(t) = -t2 + 6t + 15 represents the number of kilometers of congestion, as a function of time, registered in a city. With that, determine the maximum number of congestion in that city and the maximum time to reach this value.
Answer:
Maximum Congestion: 24
Maximum Time to reach Congestion: 3
Step-by-step explanation:
Easiest and fastest way is to graph the equation and analyze the graph for it's maximum vertex.
Answer:
t = 3
24 km of congestion.
Step-by-step explanation:
To find the maximum time, we want to know the coordinates of the vertex of the parabola. To get the x-value of the vertex, we would do -b/2a. In this case, a = -1 and b = 6. So, we will have -(6) / 2 * (-1) = -6 / -2 = 6 / 2 = 3.
To get the y-value of the vertex, just substitute the 3 whenever it says "t".
f(3) = -(3)^2 + 6 * (3) + 15 = -9 + 18 + 15 = 9 + 15 = 24
So, the maximum time it takes to reach the value is t = 3, and the maximum number of congestion in the city will be 24 km.

A (–1, 1) B (1, 1) C (1, 4) A' (–1, –1) B' (–1, 1) C' (–4, 1) Which best describes the transformation? The transformation was a 90° rotation about the origin. The transformation was a 180° rotation about the origin. The transformation was a 270° rotation about the origin. The transformation was a 360° rotation about the origin.
Answer: Transformation is the process of moving a point in a graph to another point. The new point formed is the image of the old point. When an object is transformed each point of the object is moved to another point. There are three types of transformation: Reflection, Rotation, Translation and dilation.
If a point O(x, y) is rotated 90° rotation about the origin., the new point is at O'(-y, x). That is the x coordinates becomes negative of the y coordinate and the y coordinate becomes the x coordinate.
The vertices of the triangles are shown. A (–1, 1) B (1, 1) C (1, 4), If a transformation of 90° rotation about the origin is done, the new points are A' (–1, –1) B' (–1, 1) C' (–4, 1)

Answer: 56
Step-by-step explanation:
Let's organise our information :
the radius of the circle is r=14 cm we can get the area of the shaded by substracting the area of that triangle from that quarterThe area of the cercle's quarter area is :
A= 14²×π*(1/4) = 49π cm²The area of the triangle is :
A=14²*(1/2)=98NOw the area of the shaded segment :
A=49π-98= 55.98 ≈ 56Solve for m. (-11/6) + m = -2/9
Answer:
m = [tex]\frac{29}{18}[/tex]
Step-by-step explanation:
=> (-11/6) + m = -2/9
Adding 11/6 to both sides
=> m = [tex]-\frac{2}{9} + \frac{11}{6}[/tex]
LCM = 18
=> m = [tex]\frac{-4+33}{18}[/tex]
=> m = [tex]\frac{29}{18}[/tex]
Answer:
m = 29/18
Step-by-step explanation:
(-11/6) + m = -2/9
Add 11/6 on both sides.
m = -2/9 + 11/6
Make denominators equal and add.
m = -12/54 + 99/54
m = 87/54
m = 29/18

Anita plans to cover a solid cone with construction paper for a science project. The cone has a diameter of 11 inches and
a slant height of 28.5 inches. How many square inches of paper will she need to cover the entire cone?
492.20 in.
587.18 in.
982.82 in.
984.39 in.
Answer:
587.18 square inches
Step-by-step explanation:
We would find the Total surface area of the cone
Diameter of the cone = 11 inches
Radius = Diameter ÷ 2 = 11 / 2 = 5.5 inches
Slant height ( l ) = 28.5 inches
Let's take π = 3.14
Total Surface Area of a cone = πrl + πr²
= πr(l + r)
= 3.14 × 5.5( 28.5 + 5.5)
= π × 5.5(34)
= 587.18 square inches
There the square inches of paper will she need to cover the entire cone is 587.18 square inches

Answer:
The submarine is 307.8 yards below sea level.
Step-by-step explanation:
Since the 500 yards are the hypotenuse of the right angle triangle, the acute angle opposite the side of the triangle we need to find is known ([tex]38^o[/tex]), we can use the sine function to solve the problem:
[tex]sin(\theta)=\frac{opposite}{hypotenuse} \\sin(38^o)=\frac{x}{500} \\500\,*\,sin(38^o)=x\\x = 307.8307\,\,yards[/tex]
which rounded to the nearest tenth is : 307.8 yards

Show that 3 · 4^n + 51 is divisible by 3 and 9 for all positive integers n.
Answer:
To prove that 3·4ⁿ + 51 is divisible by 3 and 9, we have;
3·4ⁿ is divisible by 3 and 51 is divisible by 3
Where we have;
[tex]S_{(n)}[/tex] = 3·4ⁿ + 51
[tex]S_{(n+1)}[/tex] = 3·4ⁿ⁺¹ + 51
[tex]S_{(n+1)}[/tex] - [tex]S_{(n)}[/tex] = 3·4ⁿ⁺¹ + 51 - (3·4ⁿ + 51) = 3·4ⁿ⁺¹ - 3·4ⁿ
[tex]S_{(n+1)}[/tex] - [tex]S_{(n)}[/tex] = 3( 4ⁿ⁺¹ - 4ⁿ) = 3×4ⁿ×(4 - 1) = 9×4ⁿ
∴ [tex]S_{(n+1)}[/tex] - [tex]S_{(n)}[/tex] is divisible by 9
Given that we have for S₀ = 3×4⁰ + 51 = 63 = 9×7
∴ S₀ is divisible by 9
Since [tex]S_{(n+1)}[/tex] - [tex]S_{(n)}[/tex] is divisible by 9, we have;
[tex]S_{(0+1)}[/tex] - [tex]S_{(0)}[/tex] = [tex]S_{(1)}[/tex] - [tex]S_{(0)}[/tex] is divisible by 9
Therefore [tex]S_{(1)}[/tex] is divisible by 9 and [tex]S_{(n)}[/tex] is divisible by 9 for all positive integers n

The double number line below shows the number of basketball cards that represent 60% of Juan's basketball card collection. How many basketball cards are in Juan's whole basketball card collection?
Answer:
Check Explanation
Step-by-step explanation:
The number line required to answer this question is missing.
But I'll explain how to get the total number of basketball cards Juan has, given the number that corresponds to 60% of the total number of cards.
Let the total number of basketball cards be x.
The first step is to check the number line presented. We furst require the number that corresponds to 60% of all of Juan's basketball cards..
Let us assume that the number of basketball cards according to the number line is 45.
This means that
60% of the total number of basketball cards = 45
60% × x = 45
0.6x = 45
x = (45/0.6) = 75 basketball cards.
So, the way to go is just to divide the number that the number line gives (which represents 60% of the total number of basketball cards) by 0.6 to obtain the total number of basketball cards.
Hope this Helps!!!

(04.06 MC) In the graph, the area below f(x) is shaded and labeled A, the area below g(x) is shaded and labeled B, and the area where f(x) and g(x) have shading in common is labeled AB. Graph of two intersecting lines. One line f of x is solid and goes through the points 0, 4, and 4, 0 and is shaded above the line. The other line g of x is solid, and goes through the points 0, negative 1 and 2, 5 and is shaded in below the line. The graph represents which system of inequalities? y ≤ −3x − 1 y ≤ −x − 4 y ≥ −3x + 1 y ≤ −x − 4 y ≤ 3x − 1 y ≤ −x + 4 y ≤ 3x − 1 y ≥ −x + 4
Answer:
(D)y ≤ 3x − 1 y ≥ −x + 4
Step-by-step explanation:
The line f(x) is solid and goes through the points (0, 4) and (4, 0) and is shaded above the line.
The line that satisfies the point (0,4) and (4,0) is y=-x+4
Since it is shaded above the line, we have the inequality sign ≥.
Therefore, one of the lines is y≥-x+4
In the equation of the line y=3x-1
When x=0, y=3(0)-1=-1
When x=2, y=3(2)-1=5
Since it is shaded below the line, we have the inequality sign ≤ .
Therefore, the other line is y≤3x-1.
The correct option is D.
In this exercise we want to mark the correct alternative that corresponds:
The correct option is D.
The line f(x) is solid and goes through the points (0, 4) and (4, 0) and is shaded above the line. The line that satisfies the point (0,4) and (4,0) is:
[tex]y=-x+4[/tex]
Since it is shaded above the line, we have the inequality sign ≥. Therefore, one of the lines is :
[tex]y\geq -x+4[/tex]
In the equation of the line:
[tex]y=3x-1[/tex]
When: [tex]x=0, y=3(0)-1=-1[/tex]
When: [tex]x=2, y=3(2)-1=5[/tex]
Since it is shaded below the line, we have the inequality sign ≤ . Therefore, the other line is:
[tex]y\leq 3x-1.[/tex]
The correct option is D.
