What is the area of a rectangle that is 1 1 4 1 4 1 1, start fraction, 1, divided by, 4, end fraction meters long and 3 4 4 3 start fraction, 3, divided by, 4, end fraction of a meter wide?
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

In a 30° -60° -90° triangle, what is the length of the hypotenuse when the shorter leg is 8 m? Enter your answer in the box.
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.
What is the 30-60-90 Triangle?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.

Find the 75th term: 88, 81, 74, 67, 60
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

A bag contains to White blocks and one red block and 3 purple blocks what is the sample space of picking a block from the bag
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

A rectangle has a perimeter of 30 yards. If one side is 5 yards long, how long is the other side?
A. 15 yards
B. 25 yards
C. 10 yards
D. 30 yards
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

The value of the trigonometric equation after transformation is given by the value y = 3 [ sin ( x + 3 ) ] - 2
How does the transformation of a function happen?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

HELP!! Multiply and simplify and express as a mixed number
12 x 3/8
no links or files
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.
