Step-by-step explanation:
Pyramid Area
Each of the four faces is a triangle with a base of 756 feet and a height of 612 feet. The area of that triangle is ...
A = 1/2bh
A = 1/2(756 ft)(612 ft) = 231,336 ft²
The total area of the four visible faces of the Great Pyramid is ...
pyramid area = 4 × 231,336 ft² = 925,344 ft²
__
WTC Area
Each of the four rectangular side faces of the WTC tower has a base length of 208 ft and a height of 1368 ft. The area of it is ...
A = LW = (208 ft)(1368 ft) = 284,544 ft²
The area of the square top of the tower has an area that is ...
A = s² = (208 ft)² = 43,264 ft²
The total area of the four visible sides and the top is ...
WTC tower area = 4 × 284,544 ft² +43,264 ft² = 1,181,440 ft²
__
The difference between the areas is ...
WTC tower area - Great Pyramid area =
1,181,440 ft² -925,344 ft² = 256,096 ft²
The difference in visible area is 256,096 ft².

Answer:
option B
Step-by-step explanation:
Given :
[tex]y = \frac{2}{3}x + 3\\\\y = \frac{5}{2}x + \frac{7}{2}\\\\[/tex]
Step 1 : simplify the equation :
[tex]3y = 2x + 9\\\\2y = 5x + 7\\[/tex]
Step 2: Arrange the terms :
[tex]2x - 3y = - 9\\\\5x -2 y = -7[/tex]
Step 3 : Solve for x and y :
2x - 3y = - 9 ------ ( 1 )
5x - 2y = - 7 --------- ( 2 )
_____________________
( 1 ) x 5 => 10x - 15y = - 45 ---------- (3 )
( 2) x 2 => 10x - 4y = - 14 ----------- (4 )
_______________________
( 3 ) - ( 4 ) => 0x - 11y = - 31
- 11 y = - 31
[tex]y = \frac{31}{11}[/tex]
Substitute y in ( 1 ) :
2x - 3y = - 9
[tex]2x - 3 (\frac{31}{11}) = - 9\\\\2x = -9 + 3(\frac{31}{11})\\\\2x = - 9 + \frac{93}{11}\\\\2x = \frac{-99 + 93}{11} \\\\2x = \frac{-6}{11} \\\\x = \frac{-6}{2 \times 11} = -\frac{3}{11}[/tex]
Therefore the solution to the sytem is [tex]( - \frac{3}{11} , \frac{31}{11})[/tex]

On a coordinate plane, triangles P Q R and S T U are shown. Triangle P Q R has points (4, 4), (negative 2, 0), (negative 2, 4). Triangle S T U has points (2, negative 4), (negative 1, negative 2), (negative 1, negative 4). Complete the statements to verify that the triangles are similar.
Answer:
See Explanation
Step-by-step explanation:
According to The Question,
Given That, On a coordinate plane, ΔPQR and ΔSTU are shown. ΔPQR has points (4,4) , (-2,0) , (-2,4). ΔSTU has points (2,-4) , (-1,-2) , (-1,-4).
We know, Two triangles are said to be similar if their corresponding angles are equal and the corresponding sides are in proportion.The distance between two points on the coordinate plane is given as:
Distance = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]
Therefore, in triangle PQR:IQRI = [tex]\sqrt{(-2_{}-(-2)_{})^{2} + (4_{}-0_{})^{2} }[/tex] = 4
IPQI = [tex]\sqrt{(-2_{}-4_{})^{2} + (0_{}-4_{})^{2} }[/tex] = √52
IPRI = [tex]\sqrt{(-2_{}-4_{})^{2} + (4_{}-4_{})^{2} }[/tex] = 6
Now Similarly, In triangle STUISTI = [tex]\sqrt{(-1_{}-2_{})^{2} + (-2_{}-(-4)_{})^{2} }[/tex] = √13
ISUI = [tex]\sqrt{(-1_{}-2_{})^{2} + (-4_{}-(-4)_{})^{2} }[/tex] = 3
ITUI = [tex]\sqrt{(-1_{}-(-1)_{})^{2} + (-4_{}-(-2)_{})^{2} }[/tex] = 2
Now, Verifying that the triangles are similar
|QR| / |TU| = 4/2 = 2
|PR| / |SU| = 6/3 = 2
|PQ| / |ST| = √52 / √13 = 2
Hence, |QR| / |TU| = |PR| / |SU| = |PQ| / |ST|
Therefore, △PQR and △STU are similar triangles since the ratio of their sides are in the same proportion.
Answer: the answer is Complete the statements to verify that the triangles are similar.
StartFraction Q R Over T U EndFraction = ✔ 2
StartFraction P R Over S U EndFraction = ✔ 2
StartFraction P Q Over S T EndFraction = StartFraction StartRoot 52 EndRoot Over StartRoot 13 EndRoot EndFraction = ✔ 2
Therefore, △PQR ~ △STU by the ✔ SSS similarity

Step-by-step explanation:
The areas marked 1, 2, and 3 each take up 1/4 of the box. This means that the probability that you will spin the arrow and land in any of those spaces is 1/4 each.
Areas 4 and 5 are HALF the size of areas 1, 2, and 3. This means that areas 4 and 5 are half of 1/4. Half of 1/4 is 1/8.
The word "or" means that you ADD whatever two probabilities they are asking for. In this case, you add areas 3 and 5. So, add 1/4 + 1/8 = 3/8.
(an easy way to add 1/4 to 1/8 is to change 1/4 to 2/8. Then you can add the two areas easily)

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the total amount of harvest of bushels be = 9,396 bushels
And , the amount of bushels per acre = 40.5
So , number of acres of land that were harvested is A = amount of harvest of bushels / amount of bushels per acre
On simplifying the equation , we get
The number of acres of land that were harvested is A = 9,396 / 40.5
The number of acres of land that were harvested is A = 232 acres
Hence , the number of acres is 232 acres

A circle has a circumference of 18 cm. What is
the length of an arc that has a measure of 160°?
Answer:
[tex]8\:\mathrm{cm}[/tex]
Step-by-step explanation:
By definition, the length arc is a portion of a circle's circumference. The exact amount is directly proportional to the measure of the arc. Therefore, the formula for the length of an arc with measure (in degrees) [tex]\theta[/tex] is [tex]2\pi r\cdot \frac{\theta}{360}[/tex], where [tex]2\pi r[/tex] is the circumference of the circle.
Substituting [tex]2\pi r=18[/tex] and [tex]\theta=160^{\circ}[/tex]:
[tex]L_{arc}=18\cdot \frac{160}{360}=\boxed{8\:\mathrm{cm}}[/tex]
We have that The length of an arc that has a measure of 160° is
[tex]l=7.9866cm[/tex]
From the Question we are told that
Circumference of 18 cm.
Arc angle=160
Generally the equation for length of arc is mathematically given as
[tex]l=2 \pi r (\theta /360)[/tex]
Where
[tex]C=2\pi r\\\\r=\frac{18}{2\pi}\\\\r=2.86cm[/tex]
Therefore
[tex]l=2 \pi 2.86 (160/360°)[/tex]
[tex]l=7.9866cm[/tex]
Therefore
The length of an arc that has a measure of 160° is

there are 8 apples and 11 oranges in a bag. what is the ratio of the apples to oranges?
Answer:
8:11
Step-by-step explanation:
For every 8 apples, there are 11 oranges.
Answer:
8 : 11 = 8 : 11
Step-by-step explanation:
Divide both terms by the GCF, 1:
8 ÷ 1 = 8
11 ÷ 1 = 11
The ratio 8 : 11 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
8 : 11 = 8 : 11

Answer:
[tex]x^{\circ}+105^{\circ}=180^{\circ},\\x^{\circ}=z^{\circ},\\180^{\circ}-z^{\circ}=y^{\circ}[/tex]
Step-by-step explanation:
Statement 1:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 2:
True - These two angles are vertical angles (opposite to each other at intersection of two lines). All vertical angles are equal.
Statement 3:
False - These two angles are vertical and therefore are equal. Thus, they cannot have a difference of 105.
Statement 4:
False - Two of these angles form one side of a line which is equal to 180 degrees. Since the third angle is greater than zero, they cannot all add up to 180 degrees.
Statement 5:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 6:
False - These two angles are supplementary (add up to 180 degrees) because they form one side of a line and therefore cannot be equal to 105.
Answer and Step-by-step explanation:
The answers are:
x + 105 = 180 (Supplementary angles = 180 degrees)
x = z (Vertical angles are congruent)
180 - z = y (Supplementary angles = 180 degrees)

During a walk-a-thon, Noah's time in hours, t, and distance in miles, d, are related by the equation 1/3d=t.
What point on a graph would represent the time it took to walk 15 miles?
The best answer gets brainliest
Answer:
(15, 5)
Step-by-step explanation:
In this equation, the distance in miles (d) would represent the input or x-axis value on a graph, while the time in hours (t) would represent the output or y-axis on a graph. Therefore, we can substitute d for the value of 15 and solve for t to get the point on the graph.
[tex]\frac{1}{3} * 15 = t[/tex]
5 = t
Finally, we see that if d=15 then t=5. This means that this would be represented on a graph as the point (15, 5)
