Decrease £13.20 by 15%

With an explanation (working out) plzzzz

Answers

Answer 1

Answer:

£11.22

Step-by-step explanation:

100% = £13.20

50% = £6.60

10% = £1.32

5% = £0.66

so you would add 10% and 5% together which gives you 15% and 15% is £1.98

and then you could to £13.20 - £1.98 which equals to £11.22

Last year there were 30 students in the Chess Club. If the number of students in the Rubik's Cube Club was 20% greater than the number of students in the Chess Club, how many students were in the Rubik's Cube Club?

A. 30
B. 42
C. 36
D. 58 ​

Answers

C.36
you would multiply 30 times 20, then divide that total by 100 which will give you 6 then add the 6 to the 30 and get 36.

The diagram shows a 6 ft student standing near a tree. The shadow of the student and the shadow of the tree ends at point A. What is the height of the tree?

Answers

Answer: 18ft

Step-by-step explanation: I took the quiz and got 100%

The height of the tree is 8.3 ft.

To solve this problem, we have to find the angle of elevation from the student.

To do this, we have to assume or bring out a right angle triangle and solve for the.

Given that we have the distance of A to F and the point  to F

A to F = 5ftE to F = 6angle ?Trigonometric Ratio

Using trigonometric ratio,

We can find the tangent of this angle

[tex]tan\theta = \frac{opposite}{adjacent} \\tan\theta = \frac{6}{5}\\ tan \theta = 1.2\\\theta = tan^-^1(1.2)\\\theta = 50.2^0[/tex]

The angle of elevation can be calculated using sum of angles in a triangle is equal to 180 degrees

[tex]180 = 90 + 50.2 + x\\x = 180- 140.2\\x = 39.8^0[/tex]

Assuming a right angle triangle from the point the student is standing, the distance from him to the tree would be

[tex]15 - 5 = 10ft[/tex]

Let's use the tangent of the angle to find the height of the tree.

[tex]tan\theta = \frac{opposite}{adjacent} \\tan 39.8 = \frac{x}{10}\\x = 10 tan39.8\\x = 8.3ft[/tex]

From the calculations above, the height of the tree is 8.3 ft.

I need help with this please

Answers

Answer:

x + 12 ft

Step-by-step explanation:

Area = base times height.  Here we know the area (x^2 + 9x - 36) and the width (x - 3).  Since area = length times width, divide the given area by x - 3.

x^2 + 9x - 36 factors into (x - 3)(x + 12).

Dividing this result by x - 3 yields the length:  x + 12 ft

Answers

Answer:

35 degrees

Step-by-step explanation:

Sum of angles inside a triangle is 180 degrees.

Right angle is 90 degrees.

180 = 90 + (x + 46) + (x + 66) = 2x + 202

x = -11

A = x + 46 = -11 + 46 = 35
