Answer:

Step-by-step explanation:

Perimeter of the deck = (d + 5) + (d + 5) + (d + 5) + (d + 5)

1). By grouping method,

    Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)

2). Perimeter = Number of sides × Length of a side

                       = 4(d + 5)

3). Expression from problem 1,

    Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)

                      = 4d + 20

                      = 4(d + 5)

    Expression from problem 2,

    Perimeter = 4(d + 5)

    Bot the expressions are same.

3/13=v/3

9/39=13v/3

v=9/13

Answer: 13

Step-by-step explanation:

[tex]66\geq 7x-21[/tex]

add 21 both sides

[tex]87\geq 7x[/tex]

divide both sides by 7

[tex]12.4\geq x[/tex]

So more than 13 cars

Answer: Wes made more shots

Step-by-step explanation:

Answer:

f(-1) = -4

Step-by-step explanation:

f(-1) means that x = -1, so find the y-coordinate that reaches at x = -1.

As you move down on x = -1, you find that -4 is where it meets.

The value of the function at x = -1 will be -4.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The function of the given graph is as follows:-

F(x) = - ( x - 2 )² + 5

For calculating the value of the function f(-1) put the value of x in the function.

F(-1) = - ( - 1 - 2 ) ² + 5

F(-1) = - ( -3 )² + 5

F(-1) = -9 + 5 = -4

Therefore, value of the function at x = -1 will be -4.

Answer:

5

Step-by-step explanation:

Step-by-step explanation:

subtract 5 from 25 and it should look like this

2x=20

divide 2 and your is 10

Answer:

No problem! Well first off, x is 10.

Step-by-step explanation:

So you know that 2 times a certain number, plus 5, is 25. The first step to solving this problem is subtracting 5 from the total (25) to give you 20. This just makes it easier to find x, so you technically don't have to do it. So now, you know that 2 times a certain number equals 20 (because we got rid of the 5). Now, just divide your number (20) by 2, to get that x is 10. Let's check our answer.

20 + 5= 25

25= 25.

Works out!

Answer: c

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

The question is not complete.

Let us assume that the black square rotates in a circular part of radius 1 inch.

Therefore, in one full rotation the distance covered (θ) is the same as the perimeter of the circular part. Therefore:

θ = 2πr = 2π(1) = 6.28 inch

The time taken to complete one full rotation (t) is:

t = θ / v

t = 6.28 / 2

t = 3.14 seconds

yes

Answer:

1369

Step-by-step explanation:

3.7 x 10 = 37 x 37 = 1369

Answer:

distance = 10.6

Step-by-step explanation:

A's coords are (5, 6)

D's coords are (-2, -2)

So the total horizontal distance between A and D is:

5 + 2 = 7

...and the total vertical distance is:

6 + 2 = 8

Now use Pythagorean Theorem:

7^2 + 8^2 = distance^2

distance^2 = 49 + 64 = 113

distance = squareroot of 113

distance = 10.6

Answer:

Thing that I do is email the teacher and he or she will give me the answers try it yourself ok

Step-by-step explanation:

Answer:

a. The possible dimensions of the total area are;

The width of the total area is (2·x + 8) inches

The length of the total area is (2·x + 10) inches

b. The dimensions of the photos are as follows;

The length of the photos are 10 inches

The width of the photos are 8 inches

Step-by-step explanation:

a. Given that the area, A = 4·x² + 36·x + 80

We get;

A = 4 × (x² + 9·x + 20) = 4 × (x + 4) × (x + 5) = (2·x + 8)·(2·x + 10)

Therefore, the possible dimensions of the total area (photo + mat) are;

The width of the total area (photo + mat) = (2·x + 8) in.

The length of the total area (photo + mat) = (2·x + 10) in.

b. The dimensions of the photos alone are shorter than the dimensions of the photo and mat combined by 2·x each

Therefore, we have the dimensions of the photos are as follows;

The length of the photo = (2·x + 10) in. - 2·x in. = 10 in.

The width of the photos = (2·x + 8) in. - 2·x in. = 8 in.

Answer:

  $1,322.05

Step-by-step explanation:

The compound interest formula is appropriate.

  A = P(1 +r/n)^(nt) . . . principal P earning annual rate r for t years, compounded n times per year

You have P=1000, r=.07, n=12, t=4, so the balance is ...

  A = $1000(1+.07/12)^(12·4) ≈ $1000(1.322054)

  A = $1,322.05

Jennifer's ending balance is $1,322.05.

Answer:

About $603

Step-by-step explanation:

Given data

The time interval 2005-2020= 15 years

The principal amount spent= ​$290 billion

The rate= 5%

Let us apply the compound interest formula

A=P(1+r)^t

substitute

A=290(1+0.05)^15

A= 290(1.05)^15

A= 290*2.0789

A= $602.881

Hence about $603 will be spent in 2020
