Answer:
80%
Step-by-step explanation:
Given that Of the 45 staff members at SEMS ,9 were out with the flu one day in January, it means that the number of people at work
= 45 - 9
= 36
As a percentage,
= 36/45 * 100%
= 4/5 * 100%
= 80%
The percent of the teachers were at work today is 80%

A trapezoid , having a height of 14 cm , has an area
of 224 cm² . The big base measures 2 cm more than the
small base. What are the lengths of the two bases ?
it should be solved as a system
Answer:
17 cm and 15 cm.
Step-by-step explanation:
Area of a trapezoid = h/2(a + b) where h = height and a and b are the 2 bases.
so we have:
(14/2)(a + b) = 224 Distributing:
7a + 7b = 224 Dividing thru by 7:
a + b = 32
Also we have
a - b = 2 where a = longest base.
Adding the last 2 equations:
2a = 34
a = 17
So b = 17 - 2 = 15.
what is 2 pule 16 dived by 16 mulipled by 16

if you apply the changes below to the linear parent function, f(x) = x, what is the equation of the new function?
Given:
The linear parent function is
[tex]f(x)=x[/tex]
To find:
The new function after vertical stretch by a factor of 4 and flip over the x-axis.
Solution:
The transformation is defined as
[tex]g(x)=kf(x)[/tex] .... (i)
Where, k is either vertical stretch or vertical compression.
If 0<|k|<1, then the graph compressed vertically by factor |k| and if |k|>1, then the graph stretch vertically by factor |k|.
If k<0, then the graph flip over the x-axis.
It is given that the graph of f(x) vertically stretch by a factor of 4. So, |k|=4.
The graph flip over the x-axis. So, the value of k must be negative, i.e., k=4.
Using (i), we get
[tex]g(x)=-4f(x)[/tex]
We have, [tex]f(x)=x[/tex]
[tex]g(x)=-4x[/tex]
Therefore, the correct option is B.
Answer: g(x)= -4x

Find the missing length of the triangle. If necessary, round your answer to the nearest tenth
Answer:
30
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem to find the missing side
a^2 +b^2 = c^2 where a and b are the sides and c is the hypotenuse
x^2 + 40^2 = 50^2
x^2 +1600 = 2500
x^2 = 2500-1600
x^2 = 900
Take the square root of each side
sqrt(x^2) = sqrt(900)
x = 30
Answer:
x = 30
Step-by-step explanation:
[tex]a^{2} = c^{2} - b^{2}[/tex]
[tex]a^{2} = 50^{2} - 40^{2}[/tex]
[tex]a^{2} = 2500 - 1600[/tex]
[tex]a^{2} = 900[/tex]
[tex]\sqrt{a^{2}} = \sqrt{900}[/tex]
a = 30
A ladder leans against the side of a house. The angle of elevation of the ladder is 62 degrees and the top of the ladder is 14 ft above the ground. Find the distance from the bottom of the ladder to the side of the house. Round your answer to the nearest tenth.
Answer:
7.4 feets
Step-by-step explanation:
Distance from bottom of ladder to side of the house = d
θ = 62 ; height, h = 14
Using trigonometry :
Tan θ = opposite / Adjacent
Opposite = height ; adjacent = d
Tan 62° = 14 / d
1.8807264 * h = 14
d = 14 / 1.8807264
d = 7.44

Find an expression to represent the area
of the trapezoid below.
I’m a bit slow, help please
x = -0.25 and y = -6
Solve the expression: x + 2y
Answer:
-12.25
Step-by-step explanation:
To solve the expression, plug in -0.25 as x and plug in -6 as y
x + 2y
-0.25 + 2(-6)
-0.25 - 12
= -12.25
So, the solution is -12.25
