Help, am I correct? Just say yes or no.

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.

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

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:

45 Degrees

Step-by-step explanation:

This would be a right angle. The other side would be 45 Degrees. Which when you add them equals 90.

Answer:

45 degrees

Step-by-step explanation:

The following figure shown is a square

All of the angles in a square are right angles meaning that they equal 90

If a diagonal line cuts through the middle then it splits the right angle into to 45 degree angles therefore your answer is 45 degrees

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:

a-10 - 6/a+2

Step-by-step explanation:

The simplification of the expression (a²- 8a - 26) / (a + 2) is (a - 10) - 6/(a + 2).

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given b,

(a²- 8a - 26) / (a + 2)

First quotient = a

Remainder = -10a - 26

Second quotient = -10

Remainder = -6

By quotient remainder theorem,

(a²- 8a - 26) = (a + 2)(a - 10) - 6

Thus,

[(a + 2)(a - 10) - 6]/(a + 2) = (a - 10) - 6/(a + 2)

Hence "The simplification of the expression (a²- 8a - 26) / (a + 2) is (a - 10) - 6/(a + 2)".

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:

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

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.
