The surface area of the cuboid is given as follows:

147.68 cm².

What is a cuboid?

A cuboid is equivalent to a rectangular prism, having dimensions given as follows:

Length l.Width w.Height h.

The volume of the cuboid is given by the multiplication of the base area and the height, as follows:

V = Ab x h.

In which:

Ab = l x w.

Considering the base area and the volume of the cuboid, the height is obtained as follows:

120 = 30 x h

h = 120/30

h = 4 cm.

A cuboid has a square base, hence the length = width are obtained as follows:

l² = 30

l = square root of 30

l = w = 5.48 cm

Hence the surface area of the cuboid is obtained as follows:

S = 2(lw + wh + lh)

S = 2(30 + 4 x 5.48 + 4 x 5.48)

S = 147.68 cm².

find the missing angle
m∠R=

Answers

Answer:

R = 90

Step-by-step explanation:

Triangles will always equal 180 degrees. If you add 61 + 29 = 90. If two of the three angles already equal 90 degrees, then you would subtract 180 - 90. Therefore, the remaining angle would have to be 90 degrees.

y-2 = 3(x - 2)
1) parallel
2) perpendicular
3) the same line
4) neither parallel nor perpendicular

Answers

Answer:

4

Step-by-step explanation:

2x+y=12

y=-2x+12

y-2=3(x-2)

If it’s parallel to each other: the slope has to be the same.

If is perpendicular to each other: the slope should be the reciprocal to each other.

The first equation has a slope of -2

The second has a slope of 3

Neither the condition meet. So the answer is 4

Point B has coordinates ​(2​,1​). The​ x-coordinate of point A is -10. The distance between point A and point B is 15 units. What are the possible coordinates of point​ A?

Answers

Answer:

(-10, 10) or (-10, -10)

Step-by-step explanation:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]

[tex]15 = \sqrt{(-10 - 1)^2 + (y_2 -2 )^2}[/tex]

[tex]15 = \sqrt{121 + 2y + y^2 + 4}[/tex]

[tex](15)^{2} =( \sqrt{121 + 2y + y^2 + 4})^{2}[/tex]

[tex]225 = 121 + 2y + y^2 + 4[/tex]

[tex]225 = 125 + 2y + y^2[/tex]

[tex]0 = -100 + 2y + y^2[/tex]

[tex]0 = (y + 10)(y - 10)[/tex]

Step-by-step explanation:

Distance Formula:

The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 dimensional plane, the distance between points (X1, Y1) and (X2, Y2) is given by the Pythagorean theorem:

d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√

Calculate Distance

To calculate the distance between 2 points, (X1, Y1) and (X2, Y2), for example, (5, 6) and (-7,11), we plug our values into the distance formula:

d=(−7−5)2+(11−6)2−−−−−−−−−−−−−−−−−√

combining terms inside parentheses we get:

d=(−12)2+(5)2−−−−−−−−−−−√

squaring both terms we get,

d=144+25−−−−−−−√

adding the 2 results,

d=169−−−√

finally,

d=13

What is the solution to the system of equations?

Answers

Answer:

x = 4

Step-by-step explanation:

Eliminate y by setting the first equation equal to the second:

2x - 7 = -x + 5

Combining like terms, we get:

3x = 12, so that x must be 4.

Step-by-step explanation:

Let us assume that [tex] 5\sqrt 7[/tex] is a rational.

Therefore, it can be expressed in the form of [tex] \frac{p}{q}[/tex], where p and q are integers.

[tex] \implies 5\sqrt 7=\frac{p}{q}[/tex]

[tex] \implies \sqrt 7=\frac{p}{5q}[/tex]

[tex] \because [/tex] p and q are integers.

[tex] \therefore \frac{p}{5q}[/tex] is a rational number.

[tex] \implies \sqrt 7[/tex] is rational ([tex] \because [/tex] quotient of a rational number is rational)

But, it contradicts the fact that [tex]\sqrt 7[/tex]is irrational.

So, [tex]5\sqrt 7[/tex] is also irrational, because the product of rational and irrational is irrational.

This contradiction is arising out because of our wrong assumption that [tex] 5\sqrt 7[/tex] is rational.

Hence, [tex] 5\sqrt 7[/tex] is irrational.

Frontal lobe: The part of each hemisphere of the brain located behind the forehead that serves to regulate and mediate the higher intellectual functions. The frontal lobes are important for controlling thoughts, reasoning, and behaviors.

the lobe of the brain located closest to the ear. Structures in the temporal lobe are important for memory, language, and hearing, along with many other functions.

The primary visual cortex is located here and thus the occipital lobe is considered the visual center of the brain.

The parietal lobe is one of the major lobes in the brain, roughly located at the upper back area in the skull. It processes sensory information it receives from the outside world, mainly relating to touch, taste, and temperature.
