Answer:

Rate of inflation = 1.4%

Step-by-step explanation:

Given:

Nominal interest rate = 4.2%

Real interest rate = 2.8%

Find:

Rate of inflation

Computation:

Rate of inflation = Nominal interest rate - Real interest rate

Rate of inflation = 4.2% - 2.8%

Rate of inflation = 1.4%

Answer: 2 3/4 a + 1/5 b

Step-by-step explanation:

Add the like terms

The solution of the given expression is equal to 7a/4 + b / 5.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given expression is 2a + (3/4a + 1/5b). The given expression will be solved as below,

E = 2a + (3/4a + 1/5b)

E = 2a + (3/4)a + (1/5)b

E = 7a/4 + b / 5

Therefore, the solution of the given expression is equal to 7a/4 + b / 5.

Answer:

x = 18

These two angles are formed by a transversal that cuts through 2 parallel lines. This means that (5x + 2) on line m corresponds to the angle on the right of (5x-2) on line n.

Now that we can see (5x + 2) and (5x - 2) are on a straight line, we can say that (5x + 2) + (5x - 2) = 180

10x + 0 = 180

10x = 180

x = 180/10

x = 18

Answer:

Step-by-step explanation:

Answer:

y = x - 600

Step-by-step explanation:

y = mx + b , "m" is slope and "b" is y-intercept

y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])

~~~~~~~~~~~~~

y-intercept is (0, - 600) and x-intercept is (600, 0)

The slope is 1

y + 600 = x - 0

y = x - 600

Answer:

3.94 seconds

Step-by-step explanation:

h = - 16t² + 248

If stone is dropped, then h = 0

- 16t² + 248 = 0

t² = [tex]\frac{248}{16}[/tex]

t = ± [tex]\frac{2\sqrt{62} }{4}[/tex]

t < 0 is a solution of equation, but not a solution of the task

t = [tex]\frac{2\sqrt{62} }{4}[/tex] ≈ 3.94 seconds

Answer: −7.5 thousand dollars

Step-by-step explanation: Khan Academy

Using the expected value formulae, the expected value of Annie entering the tournament is -$7950

Creating a probability distribution table :

Net amount won = (500 - 100) = 400 thousand

Amount lost = 100 thousand

X ___ : - 10,000 ____ 400,000

P(X) _ : __ 0.995 _______ 0.005

Using the expected value formulae:

E(X) = (0.995 × - 10,000) + (0.005 × 400,000)

E(X) = - 9950 + 2000

E(X) = -7950

Hence, the expected value of entering the tournament is -$7950

Answer:

  45 meters

Step-by-step explanation:

The equation is given in vertex form:

  h(t) = a(t -b)^2 +c

where (b, c) is the vertex (maximum).

The values of the parameters are ...

  a = -5, b = 3, c = 45

Then the maximum height is (time, height) = (3, 45).

The maximum height of the ball is 45 meters.

Step-by-step explanation:

5x+8y>120 and x+y<20 are the two inequalities shows the set of solutions for Leah earning at least $120 and working no more than 20 hours

a relationship between two expressions or values that are not equal to each other is called 'inequality.

Let x=babysitting hours paid at $5

y=ice cream shop hours paid at $8.

Total earned >120

total hours<20

So here is what our equations will look like:

5x+8y>120

x+y<20

Convert the first equation into y>mx+b format

8y>-5x+120

y>-5/8x+15

Convert the second equation into y>mx+b

x+y<20

y<-x+20

We can also solve this mathmatically by finding the point where our equations are equal:

-5/8x+15=-x+20

Add x to both sides to get:

3/8x+15=20

subtract 15 from both sides:

3/8x=5

divide both sides by 3/8:

x=13.33

The question asks us to round to the nearest whole hour, so the minimum she can babysit is 14 hours to still make $120 a week.

Hence, 5x+8y>120 and x+y<20 are the two inequalities shows the set of solutions for Leah earning at least $120 and working no more than 20 hours
