Step-by-step explanation: JUST DID THE TEST

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.

Answer:

  A = [tex]\frac{5\pi }{6}[/tex]

Step-by-step explanation:

Given that Cos A = [tex]-\frac{\sqrt{3} }{2}[/tex]

                cos A = [tex]cos (\pi -\frac{\pi }{6} )[/tex]

                       A =  [tex]\pi - \frac{\pi }{6}[/tex]

                      A = [tex]\frac{5\pi }{6}[/tex]

Answer:

Step-by-step explanation:

This is how we do it in college, I hope I can be of some help.

First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.

9.6 miles x    5 minutes   =  48 miles x minute = 120 minutes

                      0.4 miles          0.4 miles

Answer:

the download cost for a song is $1 and $11 for a movie

Step-by-step explanation:

According to the questions, the following equations are as follows:

Let us assume the song be x

And, the movies be y

So,

20x + 13y = $163.........(i)

13x + 13y = $156........(ii)

Now solve substract second equation from the first equation

7x = $7

x = $1

And the y value is

20 + 13y = $163

13y = $163 - $20

13y = $143

y = $11

Hence, the download cost for a song is $1 and $11 for a movie

Answer:

Question 1: RS=47

Question 2: x=6

Step-by-step explanation:

Question 1:

Step 1: 3x+5=2x+15+6x-37

Step 2: 3x+5=8x-22/2

Step 3: 3x+5=4x-11

Step 4: x=16

Step 5: 2(16)+15=32+15=47

RS= 47

Question 2:

Step 1: 7x+2+25x-14=180

Step 2: 32x-12=180

Step 3: 32x=192  (divide 32 from each side)

x=6

Answer:

x = 2

Step-by-step explanation:

Rearrange terms

Subtract from both sides of the equation

Simplify

Divide both sides of the equation by the same term

Answer:

4

Step-by-step explanation:

Given that :

Total fraction of paint Carin has = 2/3 bottle

Fraction used to paint a model airplane = 1/6

Number of model. Airplanes 2/3 of a bottle could paint ;

Total fraction of paint / fraction used to paint a model airplane

(2/3) ÷ (1/6)

2/3 * 6/1

= 12 / 3

= 4 model airplanes

Answer:

false

Step-by-step explanation:

4(1) - 3(6)<12

4 - 18<12

12<12

so no the truth value is false 12 is not less than 12

Answer:

A. true

Step-by-step explanation:

If you plug in x and y, the equation is 4(1)-3(6)<12. SImplify to get 4-18<12 which is equal to -14<12 which is true.

Answer:

Amanda's

Step-by-step explanation:

Given :

3/6 + 2/4

The L. C. M of 6 and 4 = 12

(6 + 6) / 12

12 / 12

= 1

Renne's result = 5/10

Amanda's result = 1 whole

Hence, Amanda's result makes more sense.

Answer:

The experimental probability --> [tex]\frac{13}{20}[/tex]

The theoretical probability --> [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Key skills needed: Experimental vs theoretical probability, Fractions

1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)

- Theoretical probability is based on simple reasoning

- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)

2) Now with this, let's start solving:

Hope you understood and have a nice day!! :D

Answer:

Experimental Probability: 65/100 We tested the probability 100 times, 65 of those times being heads. So %65 is our experimental probability (in percentage form) of flipping a coin and landing on heads. Simplified, 13/20 is our fraction.

Theoretical Probability: 50/100 or 1/2. There are two sides to a coin, and one is heads, so the theoretical probability is 1/2. In percentage form, the probability would be %50, or 50/100.

Answer: 21.4

Step-by-step explanation: Since W=7.8 all you have to do is 29.2 - 7.8 which would give you 21.4
