Adult: £60
Child: £45
David has a family discount card.
Family Discount Card gives
1/4
off adult price
40% off child price

60 divided by 4 = 15

15 x 3 = 45

£45 = adult price

10% of £45 = £4.50

40% of £45 = £18

£45 - £18 = £27

£27 = 1 child ticket

£27 x 2 = £56

£56 = two child tickets

£56 + £45 = £101

Answer:

Step-by-step explanation:

METHOD 1

in centre it is split by 4, each angle is equal.

in a square angles add up to 360°

360/4=90°

∴∠DOC=90°

if you have to do more work or have toexplain more, or you dont get that way there is another method:

METHOD 2

since ABCD is a square it alladds up to 360°

so ∠A=B=C=D=90°

in triangle DOC anles add up to 180°

each diagonal cuts angleA,B,C and D in half

so in triangle DOC, ∠ODC=∠CDO=45

∠DOC=180-∠DOC-∠CDO       (or 180-(∠DOC+∠CDO)

∠DOC=180-45-45

∠DOC=90

E)The terminal side of a negative-measured angle is generated in the clock-wise direction from the x-axis.

Answers

Answer:

Step-by-step explanation:

D) Its vertex is at the origin

E) The terminal side of a negative-measured angle is generated in the clock-wise direction from the x-axis.

The amount of rotation between the two rays forming the angle is known as the measure of the angle

The correct options are;

The options that gives the statements that accurately describes the nature of an angle in the standard position are;

D) Its vertex is at the origin.

E) The terminal side of a negative measured angle is generated in the clock-wise direction from the x-axis

Reason:

An angle is in the standard position where the location of the angle is at the origin, the positive direction is the counterclockwise, while the negative direction is the clockwise direction

The x-axis oriented ray is known as the initial side, while the other ray forming the angle is known as the terminal side

Therefore, the correct options are;

Using the exponential growth function :

A = Pe^rt

A = final amount or growth unit

P = initial or present growth unit

Rate, r = growth rate

80 = 20e^0.07t

80/20 = e^0.07t

4 = e^0.07t

Fernando had to pay $1.40 in sales tax when he purchased a shirt . If the sales tax rate is 7% how much did his shirt cost

Answers

Answer:

$20

Step-by-step explanation:

Work backwards so Price(.07) = $1.40 so x (.07) = 1.40, solving for x then

x = 1.4/.07 so x = 20

The cost of the shirt of Fernando is $20.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Fernando had to pay $1.40 in sales tax when he purchased a shirt . The sales tax rate is 7%.

The cost of the shirt is calculated as,

$1.40 =  x (.07)

x = 1.4/.07

x = $20

Therefore, the cost of the shirt of Fernando is $20.
