Answer:

ew teachers really out here trying to make video games about school huh

Step-by-step explanation:

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:

≈ 3.74 seconds

Step-by-step explanation:

Oops! The numbers I had to work with were "The function y = –16t2 + 224..."

Answer:

25

Step-by-step explanation:

[tex]24^{2} + 7^{2}[/tex] = 625

[tex]\sqrt{625\\}[/tex] = 25

Therefore, the length of BD in rectangle ABCD is 25mm. I just did the test and it is correct. 23 is wrong.

Y•55=x

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:

x= 12

Step-by-step explanation:

The sum of both of the equasions equal up to 180. so you set up the problem like this:

(9x-4)+(6x+4)=180

15x=180

x=12

To check;

(9(12)-4)+(6(12)+4)=180

104+76=180

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.

Answer: D) Period

You could refer to this as the time period. Usually the time period is in months. So you make monthly interest payments, often with the principal mixed in somewhat.

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

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

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%
