A fair coin is flipped 20 times. If the coin lands on
heads 13 times, which statement is true?
A. The coin lands on heads 3 less times than
expected.
B. The coin lands on heads 3 more times than
expected.
C. The coin lands on heads 5 less times than
expected.
D. The coin lands on heads 5 more times than
expected.

Answers

B because it’s a 50% chance of getting heads/tails and it landed 13 times out of 20 on heads so 3 more then 50% of 20
b because the coin has a 50% chance to land on heads or tails. Which means if its flipped 20 times it has a 50% chance to land on heads which is 10 times. The coin landed on heads 13 tikes which is 3 more than 10

Happy Paws charges $16.00 plus $2.50 per hour to keep a dog during the day. Woof Watchers charges $11.00 plus $3.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.

Answers

Answer:

Equation: 2.5x + 16 = 3.75x + 11

Hours: 4

Step-by-step explanation:

Hi,

The equation would be...

2.5x + 16 = 3.75x + 11

(To find the solution, you have to set the equations equal to each other)

2.5x is the cost per hour at Happy Paws and the 16 is the charge. For Woof Watchers, the 3.75x is the cost per hour and the 11 is the charge.

Now solve...

2.5x + 16 = 3.75x + 11

Subtract 16 on both sides...

2.5x = 3.75x - 5

Subtract 3.75x on both sides...

-1.25x = -5

Divide by -1.25 on both sides...

x = 4

So at 4 hours, both services will have an equal total of cost.

Hope this helps :)

Since 1 pound of cashews costs $15, you multiply 15 by 2, to get $30, then you multiply 15 by .5 since you still have half a pound left, which then gives you $7.5, then you add 30 to 7.5, which gives you the answer of $37.5

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?

please drop an explanation, and equation thanks!

Answers

Ok so we want to cross multiply.
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

 4/9 kg            $2

------------- = --------------

    1 kg               x

Multiplying both numerators by 9, we get:

  4 kg          $18

------------ = ---------

   1 kg             x

Cross-multiplying, we get 4x kg = $18-kg.  Solving for x, we get:

        $18-kg

x = -------------- = $4.50

         4kg

1 kg of baking soda costs $4.50.

Engineers are digging a 3200-foot-long tunnel at a constant rate. After 5 months, the engineers still need to dig 1700 feet to finish the project. How much time does it take to complete the tunnel from start to finish?

Will the engineers have enough time if the project was started in December 2020 and the deadline to finish the project was in August 2021? Please explain your answer for yes or no.

Hint:
y=mx+b (slope-intercept form)
x=time
y=distance
b=3200
Start & Finish: ??
Total length=3200ft
Left over=1700ft after 5 months of digging

help/

Answers

Answer:

Part A answer: 10 2/3 months

Part B answer: No

Step-by-step explanation:

Using what we gathered from the word problem, and the hint, we know that y = distance, x = time, and b = 3200.

3200 is the total number of ft meant for the hole to be dug. If we've been digging for 5 months, and we have 1700 ft yet to be dug, then after 5 months we have dug (3200 - 1700 =) 1500 ft in 5 months.

-1500 ft/5 months = 300 ft/month

-Digging the final 1700 ft will take 5 2/3 months

^ Using this information, we know that the total number of months it takes to dig the entirety of the tunnel is 10 2/3

In the second part of the problem, we're asked to determine whether or not a deadline of August 2021 was enough time to complete the 10 2/3 month-long project if the digging began in December of 2020.

If said project commenced in December 2020, and the deadline was August 2021, then there would be 1, 2, 3, 4, 5, 6, 7, 8... Roughly 8 1/2 months to complete the tunnel. 10 2/3 months is > (greater than) 8 1/2 months. So, no. That start-to-finish deadline would not be enough time.

Good luck!!
