Answer:

4 11/16 m²

Step-by-step explanation:

The formula for the area of a rectangle = Length × Width

From the question:

Length = 1 1/4 m

Width = 3 3/4m

Area of the rectangle =

1 1/4 m × 3 3/4 m

= 5/4 m × 15/4 m

= 75/16 m²

= 4 11/16 m²

Area of the rectangle = 4 11/16 m²

Answer: 4 and 1/2

Step-by-step explanation: Ok so 12 is a whole number so to turn it into a fraction put it over one as in 12/1.

Then just multiply 12/1 x 3/8 which equals 36/8 But we aren't done!

now we must calculate how many times 8 goes into 36 without going over 36 which is 4. 8 times 4 is 32 so we have 4 leftover. Now writing this as a fraction is 4   4/8. 4 is the whole number and that 4 represents 8 going tinto 36 4 times like we just demonstrated. since 36-32 is 4 thats how you get a 4/8 as your fraction.

Then you just simplify your fraction and 4  4/8 turns into just 4   1/2.

I really hope I explained this well and you understand it! :)

Answer:

C. 10

Step-by-step explanation:

5+5=10

10+10=20

10+20=30

Answer:

The other is 10 yards long

Step-by-step explanation:

For a given rectangle

Perimeter (P) = 30 yards

and one of rectangle is 5 yards

Now,

Perimeter of rectangle

P = 2l + 2b

30 = 2(5) + 2b

30 = 10 + 2b

30 - 10 = 2b

20 = 2b

b = 20 ÷ 2

b = 10 yards

Thus, The other is 10 yards long

Answer:

1/36

Step-by-step explanation:

Probability is the likelihood of chance that an event will occur. Mathematically,

Probability = expected outcome/total outcome

If a bag contains two white blocks, one red block and 3 purple block

Total outcome = 2+1+3= 6

Probability that white ball is selected = 2/6

Probability that red ball is selected = 1/6

Probability that white ball is selected = 3/6

Probability of picking a ball is 2/6 × 1/6 × 3/6

Probability of picking a ball = 6/216

Probability of picking a ball = 1/36

Answer:

86.33 square micrometers

Step-by-step explanation:

A silicon wafer is textured to minimize light reflection. This results in a surface made up of square pyramids. Each triangular face of one of the pyramids has a base of 5 micrometers and a height of 5.6 micrometers. Find the surface area of the pyramid, including the base.

The formula for the Surface Ares mma is given as :

A=a² + 2a √a²/4+ h²

a = base edge = 5 micro meters

h = height = 5.6 micro meters

=5²+2× 5 × √5²/4+ 5.6²

= 86.32699 square micrometers

≈ 86.33 square micrometers

Answer:

a₇₅ = - 430

Step-by-step explanation:

There is a common difference between consecutive terms, that is

d = 81 - 88 = 74 - 81 = 67 - 74 = 60 - 67 = - 7

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 88 and d = - 7 , then

a₇₅ = 88 + ( 74 × - 7) = 88 - 518 = - 430

The 75th term of the arithmetic progression is -430

What is Arithmetic Progression?

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is

Tn = a + (n - 1) d, where Tₙ = nth term and a = first term.

Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP : Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the Arithmetic progression be = 88 , 81 , 74 , 67 , 60 ...

The first term of the AP is a ₁= 88

Now , the common difference of the AP d = second term - first term

                                                                      = 81 - 88

                                                                      = -7

Now , the nth term of the arithmetic progression is given by ,

Tn = a + (n - 1) d

Substituting the values in the equation , we get

T₇₅ = 88 + ( 75 - 1 ) ( -7 )

     = 88 + 74 ( -7 )

     = 88 - 518

     = -430

Therefore , the value of T₇₅  is  -430

Hence , The 75th term of the arithmetic progression is -430

Answer:

16

Step-by-step explanation:

In a 30 60 90 degree triangle, the hypotenuse is always double the shorter leg. Hope this helps! :)

The hypotenuse of the 30-60-90 triangle whose shorter leg is 8 m is: 16 m.

The 30-60-90 triangle is a right triangle whose hypotenuse length is always twice the length of the its shorter leg.

Given a 30-60-90 triangle whose shorter leg is 8 m long, therefore:

Hypotenuse of the 30-60-90 triangle = 2(length of the shorter leg)

Hypotenuse of the 30-60-90 triangle = 2(8)

Hypotenuse of the 30-60-90 triangle = 16 m.

Answer:

D

Step-by-step explanation:

I plugged each equation into a graphing calculator and compared them to see which one matched the one in the picture.

The value of the trigonometric equation after transformation is given by the value y = 3 [ sin ( x + 3 ) ] - 2

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the parent function be represented as f ( x )

Now , the value of the trigonometric function f ( x ) is

f ( x ) = 3sin ( x )

when the function is translated 3 units to the left and 2 units down , we get

y = 3 [ sin ( x + 3 ) ] - 2

Therefore , the transformed function is y = 3 [ sin ( x + 3 ) ] - 2 and the graph is plotted

Hence , the transformed function is y = 3 [ sin ( x + 3 ) ] - 2
