Answer:

$4819.5

Step-by-step explanation:

Pepe bought a box of chocolates for $ 5,950, including 19% VAT. What is the price of the box of chocolates without VAT?

The price of chocolates = $5,950

VAT = 19%

We need to find the price of the box of chocolates without VAT.

VAT is applied on the Cost price of the object.

Price = $5,950 - 19% of $5,950

[tex]=5950- 5950\times \dfrac{19}{100}\\\\=\$4819.5[/tex]

So, the price of the box without VAT is equal to $4819.5.

Answer:

B, no, yes, no, no, no, 225

Step-by-step explanation:

Answer:

Yes, 1:3.

Step-by-step explanation:

Each of the numbers on figure 2 are 3 times the number on figure 1.

The transformations that can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4) is C. a 90 clockwise rotation about the origin and a reflection over the y-axis

This refers to the mathematical process where one figure or expression is changed from one form to another that has or contains a similar value.

Given the pair of points (x, y) in the original image, it has been transformed to (-y, -x).

If we allow ABC to be first transformed onto A"B"C" by a 90° clockwise rotation, this would result in:

B(4, 1) being mapped onto B''(1, -4).

Therefore, the rule mapping ABC to A"B"C"   is (x, y)→(y, -x)

With this, we can conclude that the transformation that maps (y, -x) to (-y, -x) is a reflection with respect to the y-axis

Option C is the correct transformation.

Answer:

C

Step-by-step explanation:

Answer:

32

Step-by-step explanation:

the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.

this is what it would look like.

16, 21, 28, 30, 34, 45, 58, 60

(basically how it is in the problem lol)

since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30  and 34.

you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)

(30+34)/2

we divide by two because there are two numbers.

(30+34)/2

(64)/2

if this didn't make sense - sorry - but you can watch this video: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/mean-and-median/v/mean-median-and-mode

Answer:

the answer is (c)

Step-by-step explanation:

-(-1)-13= 1-13=-12

Answer:

-1

Step-by-step explanation:

You need to take -13 behind the = sign and it will become +13. Now -12+13=-1. Again it is -x because of which 1 will be divided by - and the answer will be -1

Answer:

Step-by-step explanation:

Let d be the diameter of the wheel.

Circumference = πd

(35.325 m)/(25 revolutions) = (1.413 m)/revolution

πd = 1.413

d = 1.413/π = 0.45 m

The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.

In a 45°-45°-90° triangle, the legs and hypotenuse occur in a ratio of 1 : √2. This means

(1) x = 48 √2

(2) 88 = √2 x   →   x = 88 / √2 = 44 √2

You could also set up trigonometric equations to solve for x in each case:

(1) cos(45°) = 48 / x   →   x = 48 / cos(45°) = 48 / (1 / √2) = 48 √2

(2) cos(45°) = x / 88   →   x = 88 cos(45°) = 88 (1 / √2) = 44 √2

Responder:

c = 15

Explicação passo a passo:

se -3 é a solução para a expressão x² - 7x - 2c = 0, para obter c, vamos substituir x = -3 na equação (uma vez que é uma raiz)

x² - 7x - 2c = 0

(-3) ² - 7 (-3) - 2c = 0

9 + 21 - 2c = 0

30 - 2c = 0

30 = 2c

Trocar

2c = 30

c = 30/2

c = 15

Portanto, o valor de c é 15

9.36=.39x

26=x

Answer:

24 stamps

Step-by-step explanation:

13.66 - 4.3 = 0.39s

9.36 = 0.39s

Divide both sides by 0.39

24 = s

Or turn it:

s = 24

Hexagon and rectangle

Step-by-step explanation:

Answer:

210 m

Step-by-step explanation:

Perimeter is the distance around the outside of a two-dimensional shape.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

Christen ran around the soccer field, so she ran around the perimeter.

We can find the perimeter by adding all of the side lengths.

Perimeter=60 m+45 m+60 m+45 m

Christen ran 210m.
