Answer:

£69

Step-by-step explanation:

Given information:

Cost of dress = £50
Cost of shoes = £43
Discount offer: Buy a dress and shoes together and get 1/3 off the price.
Shipping & handling charge = £7 (added after the discount is applied)

Cost of buying a dress and shoes:

⇒ £50 + £43 = £93

Discount:

⇒ 1/3 of £93 = 1/3 × 93 = £31

Cost of goods after discount is applied:

⇒ £93 - £31 = £62

Addition of shipping and handling:

⇒ £62 + £7 = £69

Therefore, Ruth will pay £69 if she buys a dress and shoes.

(01.01 MC) Monica earned $60 from a bonus plus $8.50 per hour (h) she worked this week. Which of the following expressions best

Anna11 [10]

Answer:

Option (1)

Step-by-step explanation:

Monica earned a bonus = $60

Per hour earning in addition to bonus = $8.50

Let she worked for 'h' hours this week.

Then total earning from the hourly rate = $8.50h

Total earning for the week = Earning of 'h' hours + Bonus earned

= $(8.50h + 60)

Therefore, Option (1) will represent Monica's earnings for the week.

How many triangles can be constructed with angles measuring 80 degrees , 80 degrees and 40 degrees

daser333 [38]

Answer:

None

Step-by-step explanation:

The angles inside a triangle add to 180. If the angles are 80, 80 and 40, then they must add to 180 to form a triangle.

80+80+40 = 200

This can't be a triangle.

The water level in a port is described by the function y=3.7 Cos(pi(x)/6)+5, where y represents the water level measured

Harrizon [31]

Answer:

the answer would be 3.1 hours.

Step-by-step explanation:

Graph the equation.

Put all the answers in graph like

x=1.6

x=3.1

x=14.4

x=19.6

Now the question asks when the first tide is expected to reach a depth of 12 meters

So put y=12 because y is water level in METERS as it says in the question

and you can clearly see that 3.1 crosses answer.

Here is a photo of the the graph (Desmos)

Good luck on your other work boys!

Given the binomials (x - 3), (x - 1), (x + 2), and (x + 3), which one is a factor of f(x) = 2x3 + 3x2 - 2x - 3?

spayn [35]

Answer:

(x-1) is factor of our function.

Step-by-step explanation:

We are given a function $f(x)=2x^{3} +3x^{2} -2x-3$ and we are asked to find the correct factor from the given options.

Let us factor out our polynomial.

$2x^{3} +3x^{2} -2x-3$

$x^{2} (2x+3)-1(2x+3)$

$(x^{2} -1)(2x+3)$

$(x+1)(x-1)(2x+3)$

Therefore, (x-1) is correct choice for factor of our polynomial.
