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:

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:

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

Answer:

2280

Step-by-step explanation:

As in understandable steps,

1512x12 = 18144

18144 / 7

= 2592

2592 - 312

= 2280

An equation is formed of two equal expressions. John's salary before the pay raise is $2280.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the pay of John before the raise be x.

As it is stated that John's pay was increased by $312. And he saves 7/12 of his pay which is equal to $1512. Therefore, the equation that can represent the current saving John has,

[tex]\dfrac{7}{12}(x+312)=1512\\\\(x+312) = \dfrac{1512 \times 12}{7}\\\\x+312= 2592\\\\x =2592-312\\\\x = 2280[/tex]

Hence, John's salary before the pay raise is $2280.

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)

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:

y < 14/3

Step-by-step explanation:

You can immediately negate the negative from both sides by canceling the -1.

Divide both sides by 3, when you divide a < or > by anything you have to switch the sign it faces. So in this case

-3y > -14

=> 3y < 14

y < 14/3

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

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.
