Fran's filing cabinet is 6ft in height, 1 1/3 ft wide, and 3ft long. She plans to paint all sides except the bottom of the cabinet. I have to Find the area of the sides she intends to paint.

Answers

Answer:

Area of the cabinet to be painted = 56 ft²

Step-by-step explanation:

The cabinet is shown in the diagram. To find the surface area of the cabinet we will find the surface area of the rectangular cuboid.

Surface Area= 2 lb+ 2hb + 2lh

where l = length , b= breadth and h= height.

From the figure we see that the area of the bottom is given by length * breadth so deducting this from the total surface area of the cuboid gives the surface of the cabinet.

Area of the cabinet to be painted= lb+ 2hb + 2lh

Putting the values we get

Area of the cabinet to be painted = lb+ 2hb + 2lh

= 3* 1 1/3 + 2( 6 * 1 1/3) + 2( 3* 6)

= 3* 4/3 + 2( 6 * 4/3) + 2( 3* 6)

= 4+ 2(8) +2(18)

= 4+16+ 36

56 ft²

This is the outside area of the cabinet which is found front,back, top and two sides that need to be painted.

What is a chord?

In geometry, a chord is a line segment that connects two points on the circumference of a circle. The two endpoints of the chord lie on the circle, and the chord divides the circle into two segments - the major segment and the minor segment.

Here,

From the figure,
Apply Pythagoras' theorem,
KL² = NL² + NK²
15² = 9² + NK²
NK = √144
NK = 12

Thus, the required value of the NK in the given figure is NK = 12.

Answers

Answer:

1. a = 16, b = 14

2. a = 16.5, b = 23.2

3. a = 7.25, b = 6.5

4. a = 8.4, b = 20

Step-by-step explanation:

Problem One:

2a + 6 = 3a - 10

6 = a - 10

16 = a

6b - 3 = 81

6b = 84

b = 14

Problem Two:

4a - 8 + 8a - 10 = 180

12a - 18 = 180

12a = 198

a = 16.5

8(16.5) - 10 = 5b + 6

122 = 5b + 6

116 = 5b

b = 23.2

Problem Three:

5b - 7 = 3b + 6

2b - 7 = 6

2b = 13

b = 6.5

2a = 3(6.5) - 5

2a = 14.5

a = 7.25

Problem Four:

3a + 1.8 = 4a - 6.6

1.8 = a - 6.6

8.4 = a

10(b + 8) = 10(1.4b)

10b + 80 = 14b

80 = 4b

20 = b

Answer:

Properties of a parallelogram

Opposite sides and angles are congruentDiagonals bisect each otherAdjacent interior angles are supplementary#13

Opposite sides

2a + 6 = 3a - 10 ⇒ 3a - 2a = 6 + 10 ⇒ a = 166b - 3 = 5*16 + 1 ⇒ 6b = 81 + 3 ⇒ b = 84/6 ⇒ b = 14#14

Opposite and adjacent angles

(4a - 8) + (8a - 10)= 180 ⇒ 12a= 180 + 18 ⇒ 12a= 198 ⇒ a= 16.5°5b + 6 = 8*16.5 - 10 ⇒ 5b = 122 - 6 ⇒ 5b = 116 ⇒ b = 116/5 ⇒ b = 23.2°#15

Diagonals

5b - 7 = 3b + 6 ⇒ 5b - 3b = 6 + 7 ⇒ 2b = 13 ⇒ b = 6.52a = 3*6.5 - 5 ⇒ 2a = 14.5 ⇒ a = 7.25#16

Opposite sides and alternate interior angles

1.4b = b + 8 ⇒ 0.4b = 8 ⇒ b = 8/0.4 ⇒ b = 203a + 1.8 = 4a - 6.6 ⇒ 4a - 3a = 1.8 + 6.6 ⇒ a = 8.4

what is the value of x? 26 degrees tangent lines

Answers

Answer:

154°

Step-by-step explanation:

The central angle and the angle between the tangents are supplementary, so

x + 26° = 180° ( subtract 26° from both sides )

26 - 26 = 0

180 - 26 = 154

x = 154°

The value of the x will be 154°.

How to find the interior central angle?

The central angle and the angle between the tangents are supplementary.

If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to line L.

So,

x + 26° = 180°

Subtract 26° from both sides;

x + 26 - 26 = 180 - 26

x = 154°

Hence, the value of the x will be 154°.

Answers

Answer:

17.8

Step-by-step explanation:

Using the SOH CAH TOA identity

Opposite = 16

Hypotenuse = QR = x

Angle of elevation = 64 degrees

Sin64 = opp/hyp

Sin 64 = 16/x

x = 16/sin64

x = 16/0.8898

x = 17.8

Hence QR is 17.8 to the nearest tenth of a foot

Cost of shopping trip: $25.00

Find tax amount at 5%

$30.00

$26.25

$1.25

$5.00

Answers

Answer:

$1.25

Step-by-step explanation:

Given: the cost of the shopping trip is $25.00

They want us to find the tax amount at 5%.

Saying that we need to find the 5% of the $25.00.

Convert 5% to 0.05, then take it times 25.

$25 x 0.05 = $1.25

That should give you the 5% of the $25.

If you add $25.00 and the $1.25 together, it should give you $26.25, included with the tax.

Answer:

26.25

Step-by-step explanation:

first we have to add 25.00 plus 5%

Answers

Answer:

x=38°

Step-by-step explanation:

x° and 52 make up a right angle, which is 90°, so for an equation you can do

x+52=90

subtract 52 on both sides and you get

x=38

The two smaller angles, when added together = a right angle, which = 90°. You’ll see them called “complementary angles” (add up to 90°)

So 52 + x = 90
x = 38

Sophie has 7 cookies she wants to share equally with ten friends at her party. Part A If she separates all of the cookies and gives each friend an equal amount, how much cookie will each friend receive? Part B If Sophie wanted to give each friend 1 1/2 cookies, how many more cookies would she need?

Answers

Answer:

Each friend gets 0.7 cookie

8 cookies

Step-by-step explanation:

Number of cookies = 7

Number of friends = 10

how much cookie will each friend receive?

Number of cookie each friend get = number of cookies / number of friends

= 7/10

= 0.7 cookie

Each friend gets 0.7 cookie

If each friend 1 1/2 cookies

how many more cookies would she need?

Total number of cookies needed = 1 1/2 × 10

= 3/2 × 10

= 30/2

= 15 cookies

She already has 7 cookies

Number of cookies needed more = 15 cookies - 7 cookies

= 8 cookies
