tom gets a bonus of 30% of £96
sally gets a bonus of £31.40
work out the difference between the bonus that tom gets and the bonus that sally gets
Answer:
The difference between the bonus is £2.6
Step-by-step explanation:
First, you have to calculate the amount that Tom get for his bonus. So you have to multiply 30% to £96 :
[tex] \frac{30}{100} \times 96 = 28.8[/tex]
Next, you have to subtract Tom's amount from Sally's amount because Sally has the higher amount of bonus than Tom :
[tex]31.4 - 28.8 = 2.6[/tex]

The answer in this question is Alternate interior angles are congruent.
Step-by-step explanation:
Alternate interior angles are defined as when the two lines are crossed by another line which is called transversal, the pairs of angles on opposite sides of the transversal but inside the two lines are known as alternate interior angles.

Step-by-step explanation:
f(x) = x + 2
g(x) = x - 4
(f g)(x) =
0 2x- 2
O x² – 8
o x² – 2x- 8
o x² + 2x - 8
Answer:
(fg)(x) = x^2 -2x -8
Step-by-step explanation:
(fg)(x) = f(x)·g(x) = (x +2)(x -4)
= x(x -4) +2(x -4) = x^2 -4x +2x -8
= x^2 -2x -8 . . . . matches the 3rd choice

Can anybody help me solve for surface area?
(Formula=add all the areas of the faces)
Answer:
230.3cm^2
Step-by-step explanation:
surface area: sum of all faces
base: 12 x 2.5 = 30cm^2
back: 84 cm ^2
cross section x 2 = 7 x 2.5 = 17.5
use Pythagoras theorem to find the width of slope: 7^2 + 2.5^2 = 49 + 6.25 = 55.25. square root of 55.25 = 7.4
so, area of slope : 7.4 x 12 = 88.8cm^2
sum of all areas: 114 + 106.3 = 230.3

Write a coordinate proof to prove that the segment that joins the vertex angle of an isosceles triangle to the midpoint of its base is perpendicular to the base .
Answer:
Given: An Isosceles Triangle ABC with a vertex at B.
Midpoint M of the base AC.
To Prove: BM is perpendicular to AC.
Proof:
Let the coordinates of the points of the isosceles triangle be given as:
A = (-k, 0)
Vertex, B = (0,a)
C = (k, 0)
Midpoint, M = (0,0)
Slope of the base segment, AC:
[tex]=\dfrac{dy}{dx} = \dfrac{0 - 0}{k - (-k)} = \dfrac{0}{2\cdot k}[/tex]
Slope of the base segment, AC= [tex]\dfrac{0}{2\cdot k}=0[/tex]
Slope of the segment that joins the vertex angle of an isosceles triangle to the midpoint of its base, BM.
[tex]\text{Slope of BM =} \dfrac{0 - a}{0 - 0} = \dfrac{-a}{0}\\[/tex]
[tex]\text{Slope of BM = } \dfrac{-a}{0}[/tex] = Undefined
Two lines are perpendicular if the gradient of one is a negative reciprocal of the other.
Since [tex]-\dfrac{a}{0}[/tex] is a negative reciprocal of 0 for arbitrary values of a, BM and AC are perpendicular.
This concludes the proof.

What is the approximate loudness of a rock concert with a sound intensity of 10–1?
A.) 2 Db
B.) 22 Db
C.) 60 Db
D.) 110 Db
Answer:
22
Step-by-step explanation:
Im sure because my sister got the same question on a test and she put 22 and got it right
The loudness of a rock concert with a sound intensity of 10⁻¹ is 110 dB.
EquationAn equation is an expression used to show the relationship between two or more variables and numbers.
Given that:
L = 10log(I / I₀)
Where L is the loudness, I is the sound intensity and I₀ = 10⁻¹².
For I = 10⁻¹:
L = 10log(10⁻¹ / 10⁻¹²) = 110 dB
The loudness of a rock concert with a sound intensity of 10⁻¹ is 110 dB.

Kurt and Drew walk the same distance to school. Their start and end times are different.
Who got to school faster, and by how many minutes?
Kurt
Answer:
Option C.
Step-by-step explanation:
Kurt started for the school at 07:35 and ends at 08:25.
Time taken by Kurt to reach the school
= 08:25 - 07:35
= (07 hours + 85 minutes) - (07 hours + 35 minutes) [Since 08 hours + 25 minutes = 07 hours + (60 + 25)minutes]
= 85 minutes - 35 minutes
= 50 minutes
Time taken by Drew to reach the school
= 08:30 - 07:55
= (07 hours + 90 minutes) - (07 hours + 55 minutes) [Since 08 hours + 30 minutes = 07 hours + (60 + 30)minutes]
= 90 minutes - 55 minutes
= 35 minutes
Difference in the time taken by Kurt and Drew = 50 - 35 = 15 minutes.
Therefore, Drew is 15 minutes faster than Kurt.
Option C. is the answer.

Answer:
45
Step-by-step explanation:
Since angles 4 and 2 are the same, we will have to do x+30 is = to 2x+15. After that x= 15. Substitute x in x+30. Which results in 45
Answer:
45°
Step-by-step explanation:
Corresponding angles are equal. ∠4 and ∠2 are equal.
[tex]x+30=2x+15[/tex]
Add -x and -15 on both sides of the equation.
[tex]30-15=2x-x[/tex]
[tex]15=1x[/tex]
∠4 = x+30
Put x as 15 in the equation.

Which graph represents the function f(x) = 1/x+3
-2
Answer:
Step-by-step explanation:
To eliminate ambiguity please use parentheses when typing a function like this one. I'm going to assume that you meant
f(x) = 1 / (x + 3) - 2
Start with the graph of y = 1/x. Its vertical asymptote is the line x = 0. The graph never touches the x-axis.
Translating the entire graph 3 units to the left will give you the function
h(x) = 1 / (x + 3).
Translating the above graph 2 units down will give you the desired function g(x) = 1 / (x + 3) - 2.

Answer:
So we can ignore the endings because they all have to same endings. We know that 10^2 = 100 We see only 2 answers that have that a and b. But we also need to get the n to the power. So we power each number in the parenthesis by 2. Only A lets you power both 10 and n at the same time.

Answer:
The frequency of the class interval 225 – 230 is 4
Step-by-step explanation:
The frequency of the class interval can be seen as how many times that elements within the class interval appeared.
To do this we will have to count out all the numbers that are bigger than 225 but less than 230. These are the elements in this class (225 - 230).
They include:
225, 227 228, 225
Hence there are 4 elements in this class.
