The surface area of the solid cuboid 7m 6m and 3m. total surface area of cuboid is 162 [tex]m^{2}[/tex].

A cuboid is a six-sided solid known as a hexahedron in the geometry. Quadrilaterals make up its faces. Cuboid implies "like a cube," in the sense that a cuboid can be converted into a cube by varying the length of its edges or the angles between its faces. A cuboid is a convex polyhedron with the same polyhedral graph as a cube in mathematics.

A cube with six square faces, a rectangular prism, rectangular cuboid, or a rectangular box with six rectangle faces are special situations. In both circumstances, the faces of the cube and the rectangular prism come together at a right angle.

The missing side length that is represented by x in the triangles that are similar is: B. 5.

According to the similarity theorem, the corresponding side lengths of two triangles that are similar have the same ratio and are therefore proportional to each other.

The two triangles are considered similar to each other, this means that their corresponding side lengths would be proportional to each other and would have the following equal ratio:

45/9 = 25/x

Cross multiply

(45)(x) = (9)(25)

45x = 225

Divide both sides by 45

45x/45 = 225/45

By the degfinition of a congruent triangle, the statement that was made that ∆JOL and ∆IOM are congruent triangles is false.

The two triangles are said to be congruent triangles based on the fact that all of their corresponding sides are the same and said to be equal. Then all of the corresponding sides of the angles would also have an equa; measure.

The definition that I have given above says that the congruent triangles are those that have the same shapes and also have the same sizes. The corresponding sides of the angles and the sides would also be the same.

In the diagram that we have here, we can see that IOM and JOL do not have the same size. Hence the congruent law is not correct. To be congruent it would have to be that the the corresponding sides are the same and there is the equality in the angles of the triangles.

Since this property is not in the shape we would have to conclyde that the statement is wrong. They are not congruent triangles.

The additional money Ms. May must invest at rate of 4% to get the 5% interest on entire income is $16,000.

For the given question,

The money invested by Ms. May at 7% rate of interest is $8,000.

Let 'x' be the money invested at the rate of 4%.

The interest for the total annual income is 5%.

Thus,

7%of 8,000 + 4% of x = 5%(8,000 + x)

8,000×0.07 + 0.04×x = 0.05(8,000 + x)

One possibility for resolving the inequality is (20, 60) in which x represents the number of tacos sold, and y the number of burritos sold

When graphing inequalities, the dependent variable, or y, is placed on the left side of the equation, while the other variables are placed on the right side.

The parameters are as follows:

Hudson has enough ingredients to make 90 tacos.

Each taco costs $3 to purchase.

Each burrito costs $7 to purchase.

Hudson must sell $420 worth of tacos and burritos per day.

x = number of tacos sold

y = the number of burritos sold

We need to graphically represent and solve the system of inequalities, and to identify one possible solution

The inequalities in the system are as follows:

x + y ≤ 90

3·x + 7·y ≥ 420

We have the following graphs to plot the above inequalities:

y ≤ 90 - x

y ≥ 420/7 - 3·x/7

y ≥ 60 - 3·x/7

The vertices of the feasible region's triangle are as follows from the inequality graph:

(0, 90), (0, 60), and the third vertex is found as follows for accuracy;

90 - x = 60 - 3·x/7

x = 52.5

y = 90 - x

∴ y = 37.5 at the vertex

The third vertex is (52.5, 37.5)

Therefore, the feasible region's vertices are (0, 90), (0, 60), and (52.5, 37.5), and one possible solution within the feasible region is (20, 60)

From the figure the shaded parts are two: the quadrant part and the sector part. The solution shows that:

area of the shaded part of the quadrant = area of the shaded part of the sector = ( pi * r^2) / 4 - bh/2

given data

ACD is a sector of a circle

From the figure we deduce that arc AC with line O is a quadrant of a circle. Hence the area of the shaded part of the quadrant is:

= area of a circle /4 - area of the right angle triangle

where area of a circle = pi r^2

area of triangle =  1/2 * base * height = bh/2

Area of the shaded part of the quadrant

= ( pi * r^2) / 4 - bh/2

base AO = radius of the circle = height CO

this forms an isosceles triangle and base angles of an isosceles triangle are equal. < A = < C = x

< A + < C + 90 = 180

x = 45 degrees

area of sector

= ∅/360 * pi*r^2  

= (45 / 360) * (pi*r^2)

= (pi * r^2) / 4

area of the shaded part of the sector = area of sector - area of the right angle triangle

= (pi * r^2) / 4 - bh/2

The amount of petrol consumed in one hour will be 200 liters.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

In 45 minutes, an automobile uses 150 gallons of gasoline.

Consequently, the rate of gasoline consumption in liters per minute will be

= 150 / 45

= 10 / 3  Liters per minute

We are aware that an hour is made up of 60 minutes.

The amount of gasoline that will be used in an hour will then be

The interest rates required to get a total amount of $2,420 from compound interest on a principal of $2,000 compounded 1 times per year over 2 years is 10% per year.

The interest on savings that is calculated on both the initial principal and the interest accrued over time is known as compound interest.

The concept of compound interest, also known as "interest on interest," is thought to have first appeared in Italy in the 17th century. It will accelerate the growth of a sum more quickly than simple interest, which is calculated only on the principal sum.

Money is multiplied more quickly through compounding, and the more times it is compounded, the higher the compound interest will be.

Using the formula A = P(1 + r/n)^nt

Solving for rate r as a decimal

r = n[(A/P)^(1/nt) - 1]

r = 1 × [(2,420/2,000)^{1/(1)(2)} - 1]

r = 0.1

Then convert r to R as a percentage

R = r × 100

Conversion between different units of measurement of the same quantity is called as conversion of units.

The process of conversion depends on the specific situation and the precision and accuracy of measurement.

Conversions from one unit to another should be exact, without changing the precision of the first. This is sometimes called soft conversion. It does not involve changing of the physical configuration of the unit being calculated.

'g' is the same as grams and similarly 'mg' is the same as milligrams.

Thus, when asked to convert 2 g to mg, as in the given question,

The height of the triangular prism is calculated as: 12 cm.

The volume of a right-triangular prism = 1/2(base of triangular face)(height of triangular face)(length of the triangular prism).

Given the following:

Plug in all the values into the volume formula for the triangular prism:

750 = 1/2(5)(h)(25)

750 = (1 × 5 × h × 25)/2

750 = (125h)/2

Multiply both sides by 2

750 × 2 = (125h)/2 × 2 [multiplication property of equality]

1,500 = 125h

Divide both sides by 125

1,500/125 = 125h/125 [division property of equality]

12 = h

h = 12 cm
