A cube has a surface area of 126 feet. What is the area of one face?

Answers

Answer 1

Answer:

21 square feet

Step-by-step explanation:

A cube has 6 faces, therefore 126/6 = 21 sq/ft the area of 1 face

Answer 2

The area of one face of a cube is 21 feet.

What is the surface area of cube?

Surface area of cube is the sum of areas of all the faces of cube, that covers it.

The formula for surface area is equal to six times of square of length of the sides of cube.

A cube has a surface area of 126 feet.

The area of one face is given by;

[tex]\rm Area \ of \ one \ face=\dfrac{Surface \ area}{Total \ number \ of \ faces}\\\\ Area \ of \ one \ face=\dfrac{126}{6}\\\\ Area \ of \ one \ face=21[/tex]

Hence, the area of one face of a cube is 21 feet.

find the value of x?

Answers

Answer:

30

Step-by-step explanation:

The sum of the angles of a triangle is 180

x+34 +116 = 180

Combine like terms

x+150 = 180

Subtract 150 from each side

x+150-150 = 180-150

x = 30

using the angle sum property of triangle.

According to this, sum of all angles of a triangle is equal to 180°

x° + 116° + 34° = 180°

x° + 150° = 180°

x° = 180° - 150°

x° = 30°

The staircase has three identical parallelogram-shaped panels. The horizontal distance between each panel is 4.25 inches. The area of each panel is 287 square inches. What is the value of x ?

Answers

*see attachment for diagram

Answer:

x = 20.5 in.

Step-by-step explanation:

What we are requested to find is the height of the panel/parallelogram = x

Area of each panel = base × height = 287 in.²

Given that the total length of the 3 panels which includes the length of the 2 gaps within them = 50.5 in., first, let's find the base length of each panel.

Base length of each panel = (total length - length of the 2 gaps in between the 3 panels) ÷ 3

= (50.5 - 2*4.25) ÷ 3

= 42 ÷ 3

Base length of each panel = 14 in.

✔️Next is to find the height of the panel, x.

area of parallelogram = base × height

Base = 14 in.

height = x

Area = 287 in.²

Plug in the values

287 = 14 × x

287 = 14x

Divide both sides by 14

287/14 = x

20.5 = x

x = 20.5 in.

i think it’s 1,247. explanation: take 20% of 1450 and subtract it since it’s on sale, giving you 1160 after subtracting 290. then, take 7.5% of 1160 and add it. 7.5% of 1160 is 87, so if you add 87 to 1160, you get $1,247. hope this helped!

Janelle makes a profit of 10% when she sells a bag for $900
i. What is the cost price? ii. find out how much she should have sold it for to make a profit of 15%​

Answers

Answer:

i. 818.18

ii. 940.9

Step-by-step explanation:

SP = 900

or, CP + 10% of CP = 900

or, CP + 10/100 × CP = 900

or, 110CP = 90000

or, CP = 90000/110

CP = 818.18

for profit= 15%

SP = 9000/11 + 15% of 9000/11

= 940.9

y=2x-3

Answer:

y = 2x - 3

Step-by-step explanation:

(4, 5) and (0, -3)

m=(y2-y1)/(x2-x1)

m=(-3-5)/(0-4)

m=(-8)/(-4)

m=2

y - y1 = m(x - x1)

y - 5 = 2(x - 4)

y - 5 = 2x - 8

y = 2x - 3

50 points! Given the vertices A(-4,6), B(6,6), C(6,2),find the circumcenter. I will mark brainliest. Random answers will be reported

Answers

Answer:

(1, 4)

Step-by-step explanation:

The circumcenter is the intersection of the perpendicular bisectors.

Find the two equations for the perpendicular bisectors and solve the system for intersection point.

Given the vertices A(-4,6), B(6,6), C(6,2)

Find the slope and midpoint of AB and BC

m(AB) = (6 - 6)/(6 - (-4)) = 0, this is a horizontal segment

M(AB) is

x = (-4 + 6)/2 = 1, y = (6 + 6)/2 = 6

Perpendicular bisector is a vertical line that passes through (1, 6) so its equation is:

x = 1

m(BC) is undefined as x-coordinates are same, so the segment is vertical

M(BC) is

x = (6 + 6)/2 = 6, y = (6 + 2)/2 = 4

Perpendicular bisector is a horizontal line that passes through (6, 4) so it is:

y = 4

The intersection of the lines x = 1 and y = 4 is the point (1, 4)

The circumcenter is point (1, 4)
