Answer:

Number of cake Lorna decorate[if number of cake is 4] = 14 cakes

Step-by-step explanation:

Given expression;

d = 2c + 6

Find:

Number of cake Lorna decorate[if number of cake is 4]

Computation:

We know that

Number of cake = C

Number of decorate cake = d

So,

Number of cake = 4 cakes

Using given equation to find value of 'd'

d = 2c + 6

d = 2[4] + 6

d = 8 + 6

d = 14

Number of cake Lorna decorate[if number of cake is 4] = 14 cakes

Answer:

If the diameter or radius of one circle is the same as another circle they are congruent.

Answer:

Step-by-step explanation:

So bascially decay means shrinks or shrivels. Growth means like growing, bigger, sort of like a happy plant :D.

To find if this is getting bigger or is shrinking, lets plug in something simple like 1 for the time(t). Sooo:

20,000*.88^1

Since its a 1 exponent it does nothing so:

20,000*.88

Now this is 17600 you can use calculator but if you do this in head like me all I did is multiply 88 by 2 which was simply since 8 times 2 is 16 so 160+16 is 176 then I added zeros:

y=17600

As we can see this is smaller than 20,000, so it is a decaying problem.

By what percent tho.

Well this is pretty easy to reconize once you understand where to find it.

When they talk about percentage, they mean how much it decreased by.

This is 100%-the multiplyied value.

In this case the multiplyed value is 0.88, sooo:

100%-88%=18%

So the percent amount that the value decreased by is 18%.

Hope this helps!

Answer:

downwards

Step-by-step explanation:

Given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 )

• If a > 0 then opens upwards

• If a < 0 then opens downwards

y = - 5x² + 3x - 6 ← is in standard form

with a = - 5 < 0 then graph opens downwards

Answer:

Doesn't fit

Step-by-step explanation:

There are 2.4litres in the beaker if you count the lines; they increment by 0.4 litres each. The volume of the storage container is 20 x 15 x 7 = 2100 cm^3 (cm cubed). 1 cm^3 = 1 ml; the cube can hold 2100 mL which is 2.1 litres, which is less than the 2.4 litres in the beaker, therefore it will not fit.

This beaker will not fit into this rectangular food storage container.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since,  There are 2.4litres in the beaker, they increment by 0.4 liters each.

Hence, The volume of the storage container is,

⇒ 20 x 15 x 7

⇒ 2100 cm³

Since, Here we have;

1 cm³ = 1 ml

So, The cube hold 2100 mL which is 2.1 liters,

Clearly, It is less than 2.4 liters in the beaker.

Thus, This beaker will not fit into this rectangular food storage container.

Answer:

56 sq cm

Step-by-step explanation:

SA = Area of Base + 1/2·(Perimeter of Base)·(Slant height)

= 4² + 1/2(4x4)(5)

= 16 + 1/2(16)(5)

= 16 + 40

Answer:

Length = 12 feet, Width = 10 feet

Step-by-step explanation:

Let the length of the bedroom be 'x' ft and the width of the bedroom be 'y' ft.

We know that the perimeter of a rectangle is given by,

P=2(length+width)

P=2(x+y)

It is given that, the length of the bedroom is 2 more than the width, so,

x=y+2

Putting the values in the equation of perimeter we get,

44=2((y+2)+y)

44=2(2y+2)

44/2 =2y+2

22=2y+2

2y=22−2

y= 20/2 =10

Therefore, x=y+2=10+2=12

Hence, the length of the bedroom is 12 feet and the width of the bedroom is 10 feet.

Answer:

Shirt : Pant = 2 : 3 ,  & Pant : Shirt = 3 : 2 , Linear model can be used.

Step-by-step explanation:

Ratio of ' Number of shirts sold : Number of items sold' = 2 : 5

Let the common ratio be = x

Then, number of shirts sold = 2x. And, number of total items sold = 5x.

So, number of pants sold = Number of items sold - number of shirts sold = 5x - 2x = 3x

So, shirt to pant ratio = 2x / 3x = 2 : 3 .And,  pant to shirt ratio = 3 : 2

This model can be shown in linear equation, as all are linear powered.

Answer: 8x = 56

Step-by-step explanation:

Since the information given is that Francis plants an orchard of peach trees and that he plants 56 trees in 8 equal rows, the equation that represents this situation if x is the number of trees in each row will be:

(8 × x) = 56

8x = 56

Therefore, to know the number of trees in each row, we've to find the value of x. This will be:

8x = 56

x = 56/8

x = 7

Therefore, the number of trees in each row is 7.

Answer:

El peso total del cemento es 4.5 toneladas.

Step-by-step explanation:

El padre de Noe compró 90 bultos de cemento. Cada bulto pesa 50 kg.

Para obtener el peso total de cemento comprado por el padre de Noe se calcula mediante la multiplicación entre la cantidad de bultos de cemento y el peso de cada bulto:

90 bultos* 50 kg= 4500 kg

La tonelada hace referencia a una medida de masa en el Sistema Internacional de Unidades y en el sistema métrico decimal, que equivale a un peso de 1000 kilogramos (kg). Entonces podes aplicar la siguiente regla de tres: si 1000 kg equivalen a 1 tonelada, 4500 kg equivalen a cuántas toneladas?

[tex]peso=\frac{4500 kg* 1 tonelada}{1000 kg}[/tex]

peso= 4.5 toneladas

El peso total del cemento es 4.5 toneladas.
