3) I

4) H

Step-by-step explanation:

Perimeter of a triangle formula:

P = a + b + c

1)

P = x + 6 + 3x + 2 + 2x + 4

P = 6x + 12

2)

P = 6x + 4 + 7x + 1 + 5x + 7

P = 18x + 12

3)

P = 4x - 3 + 3x + 5x - 6

P = 12x - 9

4)

P = 6x - 8 + 3x + 7 + 5x - 3

P = 14x - 4

Answer:

24°c

Step-by-step explanation:

Cuando se dice que la temperatura esta "mayor" significaria que esta aumentando y entorno subiendo a ser mas caliente. Siendo este el caso, si la temperatura a las 3:00 estaba a 12c bajo cero entonces a las 7:00 estaria a 24c. Esto es por que un aumento de tres vecesseria un aumento de 36 grados (12*3). 12c grados bajo cero seria un numero negativo y si sumamos estos numeros nos daria 24c grados.

-12 + 36 = 24

Answer:

10

Step-by-step explanation:

440=2(60+6x+10x)

220=60+16x

160=16x

x=10

h=10

The required value of h is 10 which is determined by substituting the values of a = 10, b = 6, and s = 440 in the formula the surface area of the prism of S = 2 (ab+bh+ah).

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.

We have been given data as:

a = 10, b = 6 and s = 440

The surface area of the rectangular prism is given by the formula

⇒ S = 2(ab + bh + ah)

Substitute the values of a = 10, b = 6 and s = 440 in the above formula

⇒ 440 = 2(60 + 6h + 10h)

⇒ 220 = 60 + 16h

⇒ 220 - 60 = 16h

⇒ 160 = 16h

⇒ 16h = 160

⇒ h = 160/16

⇒ h = 10

Therefore, the required value of h is 10.

Answer:

60,000 people

Step-by-step explanation:

Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,

x is the number of years after 2014

We can find the number of people that bought the cell phone in 2020. In year 2020, that will be after 6years

Substitute x = 6 into the expression

y=-30x+240

y=-30(6)+240,=

y = -180 + 240

y = 60

Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people

Given:

The explicit function is:

[tex]f(n)=1000\left(\dfrac{1}{4}\right)^{n-1}[/tex]

To find:

[tex]f(1)=?,r=?[/tex] and first 5 terms.

Solution:

The explicit formula a geometric sequence is:

[tex]f(n)=ar^{n-1}[/tex]            ...(i)

Where, a is the first term and r is the common ratio.

We have,

[tex]f(n)=1000\left(\dfrac{1}{4}\right)^{n-1}[/tex]         ...(ii)

On comparing (i) and (ii), we get

[tex]a=1000[/tex]

[tex]f(1)=1000[/tex]

And,

[tex]r=\dfrac{1}{4}[/tex]

For [tex]n=1[/tex],

[tex]f(1)=1000\left(\dfrac{1}{4}\right)^{1-1}[/tex]

[tex]f(1)=1000\left(\dfrac{1}{4}\right)^{0}[/tex]

[tex]f(1)=1000(1)[/tex]

[tex]f(1)=1000[/tex]

For [tex]n=2[/tex],

[tex]f(2)=1000\left(\dfrac{1}{4}\right)^{2-1}[/tex]

[tex]f(2)=1000\left(\dfrac{1}{4}\right)^{1}[/tex]

[tex]f(2)=1000\times \dfrac{1}{4}[/tex]

[tex]f(2)=250[/tex]

Similarly, substituting [tex]n=3,4,5[/tex], we get

[tex]f(3)=62.5[/tex]

[tex]f(4)=15.625[/tex]

[tex]f(5)=3.90625[/tex]

Therefore, [tex]f(1)=1000,r=\dfrac{1}{4}[/tex] and the first five terms are [tex]1000,250,62.5,15.625,3.90625[/tex].

Answer:

270 minutes in all

Step-by-step explanation:

First, if we know that Deena spent 45 min painting, and that Clara spent 30 min more, than to find how much Clara painted you do 45 + 30 which equals 75. To find Adam, you do 75 x 2 which = 150.

150 + 75 + 45 = 270

Answer:

the answer is 15.

Step-by-step explanation:

you find the answer by turning 25% into 0.25 then you multiple it by 60, this results in 15.

Answer:

63 is an odd number because the singular number 3 is odd meaning there will be some cards left over.

Maria's reasoning is incorrect. Because, The fact that 63 is an odd number does not necessarily mean that there are only two ways to arrange the cards into equal groups.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

To determine the number of ways that the cards can be arranged into equal groups, we need to consider the factors of 63. In this case, the factors of 63 are 1, 3, 7, 9, 21, and 63. This means that there are six possible ways to arrange the cards into equal groups of any of these factors:

1 group of 63 cards

3 groups of 21 cards

7 groups of 9 cards

9 groups of 7 cards

21 groups of 3 cards

63 groups of 1 card

So, Maria's reasoning is not correct. There are actually six ways to arrange the cards into equal groups, based on the factors of 63.

I just took this and got the answer right!!

Step-by-step explanation:

For 3 scoops = 18 cookies

Lets use the unitary method,

So for 1 scoop, how many cookies?

So, 18 /3 = 6

So, 1 scoop = 6 cookies

So for 4 scoops we will multiply by 6 (as 1 scoop = 6 cookies)

So, 4 x 6 = 24

So, 24 cookies can be made if we add 4 scoops of flour

4 scoops = 24 cookies
