Answer:
c = 20
Step-by-step explanation:
Given that,
A rectangle PQRS,
QT = c and ST = 4c-60
We need to find the value of c.
We know that the diagonals of a rectangle bisect each other such that,
QT = ST
Putting values,
c = 4c - 60
Taking like terms together,
60 = 4c - c
60 = 3c
c = 20
Hence, the value of c is 20.
25 percent of 60 students in a class failed in the test. how many students failed the test
Answer:
15 students
Step-by-step explanation:
25% = 1/4, so you can just do 1/4 of 60 or 1/4 * 60. 60/4 = 15 students.
20 over 35 equals 110 over b
Answer:
[tex]b=192.5[/tex]
Step-by-step explanation:
We can set up the following proportion:
[tex]\frac{20}{35}=\frac{110}{b}[/tex].
Cross-multiply to solve for [tex]b[/tex]:
[tex]20b=110\cdot 35,\\b=\frac{110\cdot35}{20}=\fbox{$192.5$}[/tex].

Answer:

Step-by-step explanation:
The value of the function when domain y = 30 is f ( 30 ) = -1
What are domain and range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = 14 - ( 0.5 )x be equation (1)
Now , when the domain of the function x = 30 , we get
f ( 30 ) = 14 - ( 0.5 ) ( 30 )
f ( 30 ) = 14 - 15
On further simplification , we get
f ( 30 ) = -1
Hence , the function is f ( 30 ) = -1

What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
f ( -1 ) = 2^2/3
f ( 0 ) = 2
f ( 1 ) = 0
f ( 2 ) = -6
f ( 3 ) = -24
Hence , the function is f ( 2 ) = -6

Work out

0.03
Step-by-step explanation:
S ∝ t, introduce constant, if value of S depends on t only. Let that constant be 'k'.
=> S = kt
When, S = 0.6 & t = 4:
Answer
=> 0.6 = k(4)
=> 0.6/4 = k
=> 0.15 = k
Therefore, when t = 0.2
=> S = kt

In sanja primary school the male students are 56 and female students are 44%. What are the total students?
Answer:
100
Step-by-step explanation:
Male students take up 100%-44% = 56% of the whole school.
Let x be the total number of students.
56/x = 56%
56/x = 56/100
x = 100
Therefore there are 100 students in total.

Using the logarithm, solve the following equation for x.
6400 = (8) (2^4x)
Answer:
x = 2.411
Step-by-step explanation:
6400 = (8) (2^(4x))
Divide both sides by 8 to get;
6400/8 = (2^(4x))
800 = (2^(4x))
Using logarithms, we can solve as;
Log 800 = 4xLog 2
4x = Log800/Log2
4x = 2.9031/0.3010
4x = 9.6449
x = 9.6449/4
x ≈ 2.411

Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:
[tex]\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:
[tex]\displaystyle \sin \angle B=\frac{2}{3}=0.667[/tex]
Calculating the inverse sine function:
[tex]\angle B=\arcsin (0.667)[/tex]
[tex]\boxed{\angle B=41.81^\circ}[/tex]
