Answer:
The subtrahend is 18.
27-18 = 9
Step-by-step explanation:
A subtraction number sentence is an equation that shows a number being subtracted from another number with a final answer. The first number in a subtraction number sentence is the minuend. The second number in a subtraction number sentence is the subtrahend. The answer to a subtraction problem is called the difference.
In the given example we have 27 as minuend and 9 as difference. We have to find subtrahend.
Let subtrahend be x.
Than the expression becomes:
27-x=9
Combine the like terms.
- x = 9-27
-x = -18
negative signs will be cancelled out by each other.
x= 18
Therefore the subtrahend is 18.
27-18 = 9 ....
Answer:
sin trigonometry ratio
Step-by-step explanation:
Given
See attachment for triangles
Required
Explain why
From the attached diagram, both triangles are similar triangles because
(1) the second triangle is a dilation of the first triangle by a ratio of 1.5
i.e
(2) They have angle 30 degrees, and have their right angles located at the same point
In the first triangle, the sine of 30 degrees is represented as:
This gives:
In the second triangle:
So:
By comparison:
Hence:
Answer:
Step-by-step explanation:
From the information on 60 students we write frequency distribution as
x 1 2 3 4 5 6 7 total
f 13 22 15 6 3 0 1 60
C 13 35 50 56 59 59 60
xf 13 44 45 24 15 0 7 148
x^2f 13 88 135 96 75 0 49 456
Mean = 2.67
Var = 445.92
Std dev = 21.21
I quartile = 2
III quartile = 3
20% have atmost 1
