Answer:

14 square meters

Step-by-step explanation:

the first part of this question can be to find the bases area

the base is 2 * 2 which is 4 square meters

then you find the area of the triangles

the length is 3 and the base is 2

then you multiply the amount of that by 1/2 and then by 4 because of the number of triangles there are

2 * 3 * 1/2 * 4 = 12

this is the area of the triangles added together

then you add 12 to 2 for the total

12 + 2 = 14 m^2

Answer: 5 meters

Why?:

Let the width of the room be denoted by 'W'

Since the room is three times as long as its width, the length will be '3W'

remember perimeter of a rectangle is =  2(length + width) and is given in the question as 40 meters.

      Perimeter =  2 (length + width)

                 40 = 2 (3W + W)

                 40 = 2 (4W)

                 40 = 8W

(Dividing both sides by 8), gives

                 5 = W

Answer:

l = 15

w = 5

Step-by-step explanation:

l = 3w

40 = 2l + 2w

40 = 6w + 2w

40 = 8w

8w = 40

w = 40/8

w = 5

l = 15

Step-by-step explanation:

The exact metric conversions for length, mass, and volume are ...

An inch is 2.54 cm.

A pound is 0.45359237 kg.

A pint is 0.473176473 liters.

The approximate conversions would be ...

 2 inches ≈ 5 cm

  8 pints ≈ 4 liters

Question :-

Answer :-

[tex] \rule {180pt} {2pt} [/tex]

Given :-

To Find :-

Solution :-

As per the provided information in the given question, we have been given that the Edge of the Cube is 21 cm . And, we have been asked to calculate the Volume of the Cube .

For calculating the Volume , we will use the Formula :-

Therefore , by Substituting the given values in the above Formula :-

⇒ Volume = ( edge )³

⇒ Volume = ( 21 )³

⇒ Volume = 21 × 21 × 21

⇒ Volume = 441 × 21

⇒ Volume = 9261

Hence :-

Answer:

BC||AD

Step-by-step explanation:

A parallelogram is said to be parallelogram iff it's opposite pairs of sides are parallel to each other.

Since one pair is parallel (given)

then another pair needs to be parallel.

Hence BC||AD

Answer: I pretty sure the answer is 92!

Step-by-step explanation:

75% of the test score would be 76 x 0.75 = 57

80-57 = 23

They need 23 more points to get an 80

The 23 is 25% of the final exam grade so they would need to score a 23 x 4 = 92 on the final exam

answer: 92

Answer:

10 times

Step-by-step explanation:

Let x be the amount of times you go to the gym

Option A would be 20+2x

Option B would be 4x

now the question is after how many trips would the cost be the same?

20+2x=4x

Solve the equation so

20=4x-2x

20=2x

X=10

It would take 10 times for the cost to be the same for both options

Answer:

Step-by-step explanation:

There are two methods of doing this

one is in the pin and another:

3 2/7 =23/7

7 5/14= 103/14

23/7 + 103/14 = Lcm 14

23/7 *2= 46/14

46/14 + 103/14 =149/14

149/14 = 10 9/14

Answer:

61

Step-by-step explanation:

1. let the unknown be x

2. using theorem of Pythagoras that states the hypotenuse will be equal to the sum of the other two sides we can determine that 75=14+X

3. this implies that X=75-14

4. therefore X= 61

Answer:

Answer:

[tex]1\frac{1}{6} or 1.167[/tex]

Step-by-step explanation:

[tex]\frac{1}{2} + \frac{2}{3}[/tex]                    (convert 0.5 to a fraction: [tex]\frac{1}{2}[/tex]

[tex]= (\frac{3}{3} )\frac{1}{2}+ \frac{2}{3}(\frac{2}{2} )[/tex]     (find common denominator)

[tex]=\frac{3}{6} +\frac{4}{6}[/tex]               (add the numerators together)

[tex]=\frac{7}{6}[/tex]                      (if [tex]\frac{6}{6}[/tex] is equal to 1, but we have one extra it becomes...)

[tex]=1\frac{1}{6}[/tex]                    (convert to a decimal if needed)

[tex]= 1.167[/tex]

Answer:

$140

Step-by-step explanation:

Rent alone = 400

Rent with roommate = (400 + 30%) / 2
= (400 + 120) / 2

= 520 / 2

Rent with roommate = 260

400 - 260 = 140

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

and to get it, we simply need two points off of the straight line, hmm let's use the ones in the picture below.

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{6}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}}\implies \cfrac{2}{4}\implies \cfrac{1}{2}[/tex]

Answer:

Step-by-step explanation:

Sum of interior angles in a triangle is 180degree.

<B + 15degree + 45degree = 180degree

<B = 180 - 45 - 15 = 120 degree

By sine rule,

sin<B / AC = sin<C / AB = sin <A / BC

sin120degree / 200 = sin15degree / AB = sin45degree / BC

AB = 200*sin15degree/sin120degree

= 59.77

BC = 200*sin45degree/sin120degree

= 163.30

Answer:

  g(x) = 3 + tan(πx/4)

Step-by-step explanation:

A tangent function has a period of π. In order to make it have a period of 4, it needs to be stretched horizontally by a factor of 4/π. A function is stretched horizontally by a factor of k by replacing x with x/k.

In order for the function to be shifted vertically up by 3 units, 3 must be added to the function value. That is, the transformed function becomes ...

  g(x) = tan(x/(4/π)) +3

  g(x) = tan(πx/4) +3

Answer:

y = x² + 8x + 16

Step-by-step explanation:

blue square = x × x = x²

green rectangle = 4 × x = 4x

yellow square = 4 × 4 = 16

Let y = total area of the square

⇒ y = blue square + green rectangle + green rectangle + yellow square

       = x² + 4x + 4x + 16

       = x² + 8x + 16

Area:-
