Answer:
The answer is 768.0 square inches.
Step-by-step explanation:
The surface area of a square pyramid can be calculated by adding the area of its four triangular faces to the area of its base, which is a square.
First, we'll find the area of the base:
24 inches x 24 inches = 576 square inches
Next, we'll find the area of each triangular face:
1/2 * 24 inches * 20 inches = 240 square inches
So, the total surface area of the pyramid is:
576 square inches + 4 * 240 square inches = 1,536 square inches
Finally, we'll find the surface area that is yellow:
1,536 square inches / 2 = 768 square inches
Rounding to the nearest tenth, we have:
768 square inches = 768.0 square inches
So, the surface area of the toy that is yellow is 768.0 square inches.

Now,
A = 3 _____(1)
B + C + A +B + B = 2
3B + C + A = 2
3B + C + 3 = 2
3B + C = -1
C + A + C + A + C = 2
3C + 2A = 2
Substituing A = 3.
3C + 6 = 2
3C = 2 - 6
3C = -4
C = -4/3 _____(2)
A + B + B + C = 1
Substituting A and C.
3 + 2B - 4/3 = 1
2B = 1 - 3 + 4/3
2B = (3 - 9 + 4)/3
2B = -2/3

Homework 1 triangle mid segments
The triangle mid-segments will be the two opposite or adjacent sides of a triangle.
What is the triangle?
The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.
The sum of all angle of triangle = 180
A line connecting the midpoints of two of a triangle's sides is known as the midsegment. There are always three midsegments in a triangle. The midsegment between any two sides of a triangle is parallel to and half the length of the third side, according to the Triangle Midsegment Theorem, often known as the midsegment theorem.
A midsegment of a triangle is a line segment that joins the midpoints or center of two opposite or adjacent sides of a triangle.
Hence The triangle mid-segments will be the two opposite or adjacent sides of a triangle.

A tugboat traveled -1.5 miles in 0.3 hours what was its velocity
Velocity of tugboat is -5 miles/hour .
What is velocity?The velocity of an object is the change in position (displacement) over a time interval. Velocity includes both speed and direction, thus velocity can be either positive or negative while speed can only be positive.
Given,
Displacement by tugboat = - 1.5 miles
Time taken in travelling = 0.3 hours
Velocity = Displacement/ Time
= - 1.5 / 0.3
= - 5 miles/hours

Step-by-step explanation:
I just answered this.
the first group is consistent independent, because both equations are lines with different slope. so, they have 1 intersection, which is the solution.
the second group is consistent dependent, because both equations describe the same line.
multiply the second equation by -2, or divide the first equation by -2, and you see they are identical. multiplying an equation by a factor on both sides does not change the equation or function.
so, as both lines are identical, every point on the line is an intersection and solution. therefore, there are infinitely many solutions.
the third group is inconsistent.
they represent 2 lines with identical slope but different y-interceptions. so, they are parallel and have no intersection or solution at all.
just think : there is no pair of numbers x,y, for which their sum can have 2 different results.

The solution to the above problems are given as follows:
7) m∠A = 102°. m∠B = 102.°
8) ∠QSR = 59.6°
9) ∠ADC = 55°
What is the rationale for the above solutions?7) Since both angles are vertical, it, therefore, means they are congruent. Ths,
4x + 6 = 7x-66; collect like terms
6+66 = 7x -4x
72 = 3x
x = 72/2
Thus,
x = 24
Plugging in the value of x back into the expressions, we have:
m∠A = 4x + 6
= 4(24) + 6
= 96+6
= 102°
Thus, m∠A = 102.
Since both angles are congruent, that means m∠B is also 102°
8) To find ∠QSR, we need to find x. Note that Angle on a Straight line sums up to 180°. Thus,
4x-8+34+72-x = 180
4x - 8 + 34 + 72 - x = 180
5x + 98 = 180
5x = 82
x = 16.4
So the solution is x = 16.4.
Since ∠QSR = 76-x
∠QSR = 76-16.4
Thus,
∠QSR = 59.6°
9) Applying the same rule (Angles on a straight line to the above problem, we can state that:
2x+1 + (x-7) = 180°;
To solve for x, we can simplify both sides of the equation and then isolate x:
2x + 1 + x - 7 = 180
3x - 6 = 180
3x = 186
x = 62
So the solution is x = 62.
Thus, ∠EDF = 62 - 7
= 55°
since ∠EDF and ∠ADC are opposite angles, and opposite angles are congruent,

we can identify that PQ = XY, PR = XZ,
and QR = YZ
and ∠P = ∠X,
∠Q = ∠Y and ∠R = ∠Z.
Then we can say that Δ PQR ≅ ΔXYZ.

By the given explanation,
It is proven that in given right angle triangles a² = cx.
Congruent angles:The angles that are identical to each other are known as Congruent angles. The measure of these concurrent angles is always equal to each other.
They can be acute, obtuse, exterior, or interior angles because the congruence of angles is unaffected by the type of angle. As we know a right angle is 90° all right angles are congruent angles.
Here we have
Two right-angle triangles MOP and MNO
Measurements of Δ MNO side are a, b, and c is the hypotenuse
Measurements of Δ MOP sides are a, x, and OP is the hypotenuse
Here we need to prove that a² = c x
We can prove its as follows
As we know all right angles are concurrent
Statement Reason
=> ∠NOM ≅ ∠OPM [ ∵ right-angles are concurrent ]
=> ∠OMN≅ ∠PMO [ ∵ Common angle ]
=> ΔMOP ~ ΔMNO [ By Angle - Angle - Angle criteria ]
Since ΔMOP ~ ΔMNO
=> a/x = c/a [ ratio of the corresponding side ]
=> a² = cx [ Corss multiplication ]
Therefore,
It is proven that in give right angle triangles a² = cx.

What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
Example:

We have,
ΔHIJ
m∠H = x - 1
m∠I = 2x + 5
m∠J = 7x + 6
We know that,
The sum of the angles of the triangle is 180 degrees.
m∠H + m∠I + m∠J = 180
(x - 1) + (2x + 5) + (7x + 6) = 180
x - 1 + 2x + 5 + 7x + 6 = 180
10x + 10 = 180
Take 10 common.
10 (x + 1) = 180
Divide both sides by 10.
x + 1 = 180/10
x + 1 = 18
Subtract 1 on both sides.
x = 18 - 1
x = 17
Thus,
If in ΔHIJ,
m∠H = x - 1, m∠I = 2x + 5, m∠J = 7x + 6.
The value of x is 17.

A block of wood has a volume of 270 cubic centimeters and weight 0.280 kilograms. what's its density? will it float in water?
The destiny of the block of wood is _______ 9/cm³
The density of the block of wood is 1.04g/cm³
What is density ?Density is the ratio of the mass of an object to its volume. It is a scalar quantity and it is measured in g/cm³ or kg/m³.
Density = mass/volume
Mass = 0.280kg = 0.280 × 1000 = 280g
volume = 270cm³
Density = mass/volume
Density = 280/270
= 1.04g/cm³
Because the density of the object is just slightly higher than the density of water which is 1g/cm³
, therefore the object will float in water.
For an object to float in water, it must be equal to the weight or density of the water
