Answer:

Step-by-step explanation:

Area of triangle:

A = 1/2bh

A = 1/2(2)(3)

A = 3

Area of rectangle:

A = bh

A = 11(3)

A = 33

Area of triangle:

A = 1/2bh

A = 1/2(3)(4)

A = 6

Combined:

3 + 33 + 6

What is the height of a triangle that has an area of 60 yd^2 and a base with a length of 12 yd

andriy [413]

Area = (base * height) / 2
60 = (12 * h) / 2
120 = 12h

If (x+2),3x and (4x+1)are in AP find the value of x

Gala2k [10]

Answer:

x is 3

Step-by-step explanation:

${ \bf{U _{2} - U _{1} = U _{3} -U _{2} }}$

${ \tt{3x - (x + 2) = (4x + 1) - 3x}} \\ { \tt{2x - 2 = x + 1}} \\ { \tt{x = 3}}$

Two cards are chosen from a pack of cards without replacement. Calculate the probabilities: (a) Both are picture cards. (b) Both

vovangra [49]

Answer:

A) 0.0498

B)0.2451

C) 0.2549

Step-by-step explanation:

Total number of cards N = 52

A) Number of picture cards including the king, Queen ,jack = 12

P(picture cards) = (12/52)*(11/51)

P(picture cards) = 0.0498

B) Number of red cards ( hearts and diamonds) = 26

P( red cards) = (26/52)*(25/51)

P(red cards) = 0.2451

C) Number of black cards ( Spaders and clubs) = 26

P( one red and one black cards) = (26/52)*(26/51) = 0.2549

Model: 9.5cm Actual : 30.5m The scale factor for a model is 5 cm =

Tju [1.3M]

Answer:

The scale factor for a model is 5 cm = 16.05 cm.

Step-by-step explanation:

Given:

Model: 9.5cm Actual : 30.5m and the scale factor for model is 5 cm.

Now, we need to find the actual shape for the scale factor 5 cm.

Let the actual shape be $x$ .

Now, for getting the actual shape we set for proportion:

5:x :: 9.5:30.5

5:x = 9.5:30.5

Then, convert it into fractions:

$\frac{5}{x} =\frac{9.5}{30.5}$

Now, on cross multiplying we get:

$9.5x=152.5$

Dividing both sides by 9.5 we get:

$x=16.05$

Therefore, the scale factor for a model is 5 cm = 16.05 cm.
