Is this relation a function?.

Answer:

30.4%

1000 at £1.10

1000 x 1.10 = £1100

35% of 1000 is given away

1000 - 35% = 1000 - 350 = 650 left

35% of £1100 = £385, subtract to get £715 pounds worth of pins left

650 are left, with 385 pounds lost

60% of 650 = 390 pins sold at £3 each

40% of 650 = 260 sold at £5 for 2

3 x 390 = £1170 made from the first lot

260/2 = 130 x 5 = £650 made from the second lot

£1170 + £650 = £1820 from sales

Sales - cost to make - losses (giveaways) = profit value

1820 - 1100 - 385 = 335 pounds of profit

To find the gross profit margin, we take the profit, and find what percentage of the production cost it is.

335 is about 30.45% of 1100

30.45%, which is 30.4% to 1 decimal place.

Answer:

7.04× 10^5

Step-by-step explanation:

6.72 x 10^5= 6.72 x 10^(4+1)= 6.72 x 10^1 ×10^4

= 67.2 x 10^4

(67.2 x 10^4)+ (3.2 x 10^4)

(67.2+3.2) × 10^4 = 70.4 × 10^4

Answer:

20.25 lbs

Step-by-step explanation:

Multiply 27 by 3/4 or .75 to equal 20.25.

Answer:

36 pounds.

Step-by-step explanation:

Suppose Seher's dog weigh x pounds, here is an equation:

27=[tex]\frac{3}{4}[/tex]x

multiply 4 on both sides and dividing 3 on both sides, we get:

36=x

we flip this around:

x=36

So, Seher's dog weighs 36 pounds.

The four numbers whose sum equals 0, none of which are opposites are

-2,  4, -9, 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Four numbers:

-2,  4, -9, 7

We see that,

The sum of the four numbers is 0.

-2 + 4 + (-9) + 7

= -11 + 11

= 0

None of the numbers are opposite.

Thus,

The four numbers are -2, 4, -9, and 7.

Answer:

one regular ticket costs $30

Step-by-step explanation:

The total number of people = 4

Without  the $20 coupon, the total cost would have been =100+20 = $120

Assume the price of one regular ticket is x;

4x = 120

Divide both sides by 4 to solve for x

x = 120/4

x = 30

Therefore, one regular ticket costs $30

Answer:

$30

Step-by-step explanation:

Since you pay 100 after discount, you add the 20 dollar discount to the 100 ($120)

Then since there are 4 of you in total, (you+ 3 friends), you divide by 4.

And Voila, your answer is $30 per person.

Answer: the length in the drawing is 1.166666...ft or 14 inches.

Step-by-step explanation:

there are 0.75 ft in 9 inches, and 45/0.75=60. So, to find x you need to divide 70 by 60. :))

If you needed to answer in inches, I found my answer by dividing 45/9 which equals 5, so x=70/5. x=14 inches.

Answer:

if we carefully observe, left-bottom model contains 4 units on each side of the cube.

Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].

The correct model is attached below.

Step-by-step explanation:

Given the expression

[tex]\sqrt[3]{64}=4[/tex]

Cubing both sides

64 = 4³

Thus, the cube will have 4 units on each side.

Now, if we carefully observe, left-bottom model contains 4 units on each side of the cube.

Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].

The correct model is attached below.
