Answer:

1000 tiles required.

explanation:

Tiles dimension:

Floor dimension:

Area of floor:

Length * Width

50 * 40

2000 m²

Area of each tile:

Length * Width

1 * 2

2 m²

Number of tiles required = Area of floor ÷ Area of each tile

→ tiles = 2000/2

→ tiles = 1000

See below.

1000

area of rectangle = width x length

Given: width of floor = 40 m length of floor = 50 m ⇒ area of floor = 40 x 50 = 2000 m²

width of tile = 1 m length of tile = 2 m ⇒ area of tile = 1 x 2 = 2 m² Number of tiles needed = area of floor ÷ area of one tile                                        = 2000 ÷ 2                                        = 1000

Area of triangle = 1/2 x base x height

Area of the triangle = 1/2 x 22 x 18 = 198 square m.

Area of semi circle = 1/2 x PI x r^2

Area of semi circle = 1/2 x 3.14 x 11^2 = 189.97 square m.

Total area = 198 + 189.97 = 387.97 square m.

Round up to 388 square m.

Answer:

Step-by-step explanation:

y-y1 = m (x-x1), where (x1,y1) is the point the line passes through and m is the slope

y-(-1) = 2 (x-3)

y+1 = 2x - 6

Answer:

The answer is C.

Answer:

17=x

Step-by-step explanation:

In this case, we need to use Vertical Angles Theorem to solve this problem. Basically, because of the position of the angles, they are congruent.

68-x = 3x

Add x to both sides

68=4x

Divide by 4

17=x

Hope this helps!

Answer:

The value of 'x' is: 17°

Step-by-step explanation:

From what is being shown, there are two angles that are given:

(68 - x)°

3x°

Since they are congruent angles, meaning they are equal to each other, they will be put into a(n) equation such like shown below:

(68 - x)° = 3x°

(Then remove the parenthesis)

68° - x° = 3x°

     + x°=+3x°

------------------

68° = 4x°

------------------

(Divide both sides by 4)

[tex]\frac{68}{4} = \frac{4x}{4}[/tex]

------------------

17° = x

------------------

Your value of 'x' is 17.

Given:

A race car game takes 6 points from a player each time the player hits a cone.

To find:

The integer which represents the change in total points if the player hits 10 cones.

Solution:

According to the given information,

1 hit = -6 points

Here, negative sign represents the reduction in points after hitting a cone.

If the player hits 10 cones.

(1 × 10) hit = (-6 × 10) points

10 hit = -60 points

So, the change in total points if the player hits 10 cones is -60.

Therefore, the required integer is -60.

Answer:

235 miles per hour and 2,115 miles in 9 hours

Step-by-step explanation:

First determine how many miles the jet files in one hour:

470/2 =235 miles/hour

We want to know how many hours the jet could fly in 9 hours, so we multiply this value by 9.

235 x 9 = 2115 miles

Therefore, the jet could fly 2115 miles in 9 hours.

Step-by-step explanation:

1/4 is equivalent to 2/8, but not with 1/8.

Answer:

No.

Step-by-step explanation:

To find equivalent fractions, multiply the numerator and denominator by the same number.

Start with 1/4.

Multiply the numerator and denominator by 2.

You get 2/8.

2/8 is an equivalent fraction to 1/4.

2/8 and 1/8 are not equivalent.

Answer: No.

Answer:

Step-by-step explanation:

Very simple, if the total was $12.65, and they included a 15% tip, so we do 12.65 *15%=1.8975

So we subtract that by 12.65 and our answer is approximately $10.75

the distance between two points

Answer:

Okay, here's the method I'm going to use.

If you drive north 6 miles, and then drive east 19 miles, you are technically making a triangle.

                    19 miles

           l_______________

6 milesl

           l

You are just missing the last side of the triangle: the straight line stretching from across your starting point to the ending point. You can find this by using the Pythagorean theorem.

a^2 + b^2 = c^2

6^2 + 19^2 = c^2

36 + 361 = c

397 = c

[tex]\sqrt{397}[/tex] = 19.924859

Rounded to the nearest tenth, your answer is

19.9 miles

Check the picture below, so the shaded area is really just the area of one quarter of a circle's area with a radius of 7, and a triangle whose base is 7 and height is 7, so let's simply sum both of them up.

[tex]\stackrel{\textit{\Large Areas}}{\stackrel{\textit{quarter of a circle}}{\cfrac{1}{4}(\pi)(7)^2}~~ + ~~\stackrel{triangle}{\cfrac{1}{2}(7)(7)}}\implies \cfrac{49\pi }{4}~~ + ~~\cfrac{49}{2}~~ \approx~~63.0[/tex]

Answer:

[tex]\mathsf{\cos T=\dfrac{28}{53}}[/tex]

Step-by-step explanation:

[tex]\mathsf{\cos(\theta)=\dfrac{adjacent\ side}{hypotenuse}}[/tex]

[tex]\implies \mathsf{\cos T=\dfrac{28}{53}}[/tex]

So first we have to find equation form angles.

Statement :- The measure of the second angle of a triangle is 20 more than the measure of the first.

Equation :-

second angle = 20 + x

{ Remember people get's confused when to multiply and when to add. when ever there "more than" then we will add and when there is ,"times" we will multiply}

Statement :-

the third angle is 10 less than three times the first

Now just see first less means we have to subtract 10 from 3 times the first means 3 × first angle.

Equation :-

third angle = 3x - 10

Now let's represent :-

We know sum of angles of triangle is equal to 180°

So :-

Measure of angles :-

[tex]\bold{\huge{\underline{ Solution }}}[/tex]

Let the first angle be x

According to the question,

[ 2nd angle is 20 more than the first angle ]

[ 3rd angle is 10 less than thrice times the first angle ]

By using Angle sum property

That is,

[tex]\sf{ x + ( x + 20) + ( 3x - 10) = 180{\degree}}[/tex]

[tex]\sf{ x + x + 20 + 3x - 10 = 180{\degree}}[/tex]

[tex]\sf{ 5x + 10 = 180{\degree}}[/tex]

[tex]\sf{ 5x = 180 - 10}[/tex]

[tex]\sf{ 5x = 170}[/tex]

[tex]\sf{ x = }{\sf{\dfrac{ 170}{5}}}[/tex]

[tex]\sf{ x = }{\sf{\cancel{\dfrac{ 170}{5}}}}[/tex]

[tex]\bold{ x = 34{\degree}}[/tex]

Thus,

Hence, The three angles of the given triangle are 34° , 54° and 92°

[tex]\bold{\huge{\underline{ Verification }}}[/tex]

Here, we have

By using Angle sum property :-

[tex]\sf{ 34 + 54 + 92 = 180{\degree}}[/tex]

[tex]\sf{ 88 + 92 = 180{\degree}}[/tex]

[tex]\sf{ 180 = 180{\degree}}[/tex]

[tex]\bold{ LHS = RHS }[/tex]

Hence, Verified

The length of a rectangle is 5 more than twice the width. If the perimeter of the rectangle is 34 cm find the length?

In this question we are provided with the perimeter of the rectangle = 34 cm and it is given that the length of the rectangle is 5 more than the twice it's breadth and asked to find out the length of the rectangle.

[tex] \small \orange{ \underline{\rm \blue{length \: of \: a \: rectangle \: is \: 5 \: more \: than \: twice \: the \: width.}}}[/tex]

Let us assume breadth as x then length = 2x +5

We know,

[tex] \star \: \large\boxed{ \rm{ Perimeter_{(rectangle)} = 2(length + breadth)}}[/tex]

Substituting the values we get

34 = 2(2x +5 + x)

→ 34 = 2(3x + 5)

→ 34 = 6x + 10

→ 34 - 10 = 6x

→ 24 = 6x

→ [tex]\dfrac{24}{6}[/tex] = x

x = 4

Length = 2x + 5 = 2 × 4 + 5 = 8 + 5 = 13 cm

Breadth = x = 4cm

Length = 13 cm.

Answer:

m∠JTS = 104° ⇒ (A)

Step-by-step explanation:

The measure of an exterior angle of a triangle at one of its vertices equals the sum of the measures of the opposite interior angles.

Let us use this fact to solve the question

In ΔTSR

∵ T ∈ ray RJ

∴ ∠JTS is an exterior angle of ΔTSR

→ By using the fact above

∴ ∠TSR and ∠TRS are the opposite interior angles to ∠JTS

∴ m∠JTS = m∠TSR + m∠TRS

∵ m∠JTS = 27x - 4

∵ m∠ TSR = 30°

∵ m∠TRS = 18x + 2

→ Substitute their values in the equation above

∴ 27x - 4 = 30 + 18x + 2

→ Add the like terms in the right side

∴ 27x - 4 = 18x + 32

→ Add 4 to both sides

∴ 27x = 18x + 36

→ Subtract 18x from both sides

∴ 9x = 36

→ Divide both sides by 9

∴ x = 4

→ To find m∠JTS substitute x by 4 in its measure

∴ m∠JTS = 27(4) - 4 = 108 - 4

∴ m∠JTS = 104°
