So he spent 90% of a number and had 50 left
£5. This is because 50p is 10%. To get 100% you therefore need to times 50p by 10, thus getting £5
Hope this helps!

A CLOSER LOOK AT Compound Inequalities We previously learned that compound inequalities are two inequalities joined by the word
alex41 [277]

Answer:

The sign at the ticket booth should read "Guests that are under 3 years old or over 62 years old get free admission!"

Step-by-step explanation:

Compound inequalities are the combination of two inequalities by the words "or" or "and".

In the given example, the compound inequality is,

Guests that are under 3 years old and over 62 years old get free admission!

The given inequality can be broken into two individual inequalities as,

Inequality 1: Guests that are under 3 years old get free admission

Inequality 2: Guests that are over 62 years old get free admission

The above two inequalities are combined by "and" in the given compound inequality.

Now, "and" signifies that both the conditions or inequalities should be fulfilled at the same time. But a guest can either be under 3 years old or he/she should be older than 62. Both the conditions cannot be fulfilled at the same time and hence, the sign doesn't make any sense.

To correct the sign, "and" should be replaced with "or".

Therefore, the corrected sign at the ticked booth should read "Guests that are under 3 years old or over 62 years old get free admission!".

Which rigid transformation would map ΔABC to ΔABF?
ANEK [815]

Answer:

This is a reflection in the axis or line through AB.

Step-by-step explanation:

Since a triangle is well defined other than its handedness by the length of two sides with the angle between those two sides, and noting the diagram shows that the sides and angle sandwiched are equal but for the fact that the order is reversed, so this is a reflection in the axis or line through AB.

Watch help video Given mn, find the value of x. (6x-3)⁰ (2x+13)°​
Ilia_Sergeevich [38]

Answer:

x = 4

Step-by-step explanation:

(6x - 3)° = (2x + 13)° are vertical angles that equal each other get x by itself and solve for x.

(6x - 3)° = (2x + 13)°

6x - 2x = 13 + 3

4x = 16

x = 4

Substitute x for the angles.

(6x - 3)° = ?

(6*4 - 3)° = ?

(24 - 3)° = 21°

(2x + 13)° = ?

(2*4 + 13)° = ?

(8 + 13)° = 21°
