20 is 10 times as much as 2

2 x 10 = 20

so 2 is your answer :)

A website sells a dress at £40 and shoes at £32. The website has an offer: Buy a dress and shoes together and get 1/2 off the pr

tekilochka [14]

Answer:

$\pounds36$

Step-by-step explanation:

Cost of one dress = $\pounds40$

Cost of one pair of shoes = $\pounds32$

Cost of one dress and a pair of shoes is $40+32=\pounds72$

They get half off the price because they buy both

$\dfrac{72}{2}=\pounds32$

The shipping and handling charge is $\pounds4$ .

So, the total amount Ruth has to pay is $32+4=\pounds36$ .

This is a piecewise function |x+3| ,x>2

marusya05 [52]

Answer:

Given: piece wise function-

f(x) = x + 3 for x < 0 and f(x) = 2x for x ≥ 0

First part of the function does not include x = 0.

In slope-intercept form,

slope(m) = 1

y-intercept = (0,3).

So, the conditions are shown in graphs 1 and 3.

Now, the second part of the function equation passes through origin as the equation is f(x) = 2x.

Correct choice - [B]

Note: See picture of graph attached.

Can someone help me please. (TROLLS WILL BE REPORTED!!!)

Answer:

B.) 54π units²

Step-by-step explanation:

First, we need to find the height of the cone. We can do this using the Pythagreom Theorem.

a² + b² = c² <----- Pythagreom Theorem

3² + b² = 15² <----- Insert side lengths

9 + b² = 225 <----- Solve 3² and 15²

b² = 216 <----- Subtract 9 from both sides

b = 14.7 units <---- Take square root of 216

Now, we can use the surface area of a right cone equation to find the final answer.

r = 3 units

h = 14.7 units

SA = πr(r + √(h² + r²)) <----- Surface Area equation

SA = π(3)(3 + √(14.7² + 3²)) <----- Insert values

SA = π(3)(3 + √(216 + 9)) <----- Solve 14.7² and 3²

SA = π(3)(3 + √225) <----- Add 216 and 9

SA = π(3)(3 + 15) <----- Take square root of 225

SA = π(3)(18) <----- Add 3 and 15

SA = 54π units² <----- Multiply 3 and 18

Which set of fractions is ordered from greatest to least? A two over three, three over eight, five over twelve B five over twelv

Annette [7]

Answer:

When ordering three or more fractions from least to greatest, compare two fractions at a time. It is helpful to write a number in a circle next to each fraction to compare them more easily.

He national debt of a country is $298,800,000,000,000 and the population is 53,980,000. What is the debt per person? Write t

lana66690 [7]

Answer:

5535383.47 units

Step-by-step explanation:

Given that,

The national dept of a country = 298,800,000,000,000

Population of the country = 53,980,000

We need to find the debt per person. It can be calculated by dividing national dept of a country to its total population. Let it is d.

$d=\dfrac{298800000000000}{53980000}\\\\=5535383.47\ \text{units}$

Hence, the debt per person is 5535383.47 units.
