Mathematics
1 answer:
Naddik [55]3 years ago
8 0

Answer and Step-by-step explanation:

So, the format you should choose is the second one.

This is what goes in each box:

[4] (p - [6]) = [12]

The 4 is multiplying the price for 1 of the items (and it is 4 because there are 4 items), the 6 is taking away 6 dollars (because coupons take away money from amount) and 12 is the total amount of money.

Now, we solve for <u>p</u>.

Divide each side by 4.

p - 6 = 3

Now, add 6 to each side.

p = 9.

Each item cost 9 dollars.

Which numbers are the extremes of the proption shown below. 3/4 = 6/8
Tems11 [23]

Answer:

3 and 8

Step-by-step explanation:

Given the proportion:

\frac{3}{4} = \frac{6}{8}

Required:

Find the extreme values.

When given an equation like the one we have here, there is always a very easy way to find the extreme value.

First make rewrite to a ratio form:

Example:

a:b = c:d

Just know that extreme values are the values on the outside of the ratio(a & d)

Therefore,

3:4 = 6:8

When it is written this way extreme values are 3 & 8

Extreme values = 3 and 8

Anyones good in gr5 science pls
klio [65]

Answer:

Q 1: the answer is A

Q 2: energy, vibrates, air, and waves

Q 3: #1 and B; #2 and C; #3 and A

Step-by-step explanation:

Explanation for Q 1:

Below the surface, sound waves pass directly through the water and into your head. You're witnessing evidence that water is a good conductor of sound. For starters, sound travels through water five times faster than it travels through air.

Explanation for Q 2:

Sound is a type of energy made by vibrations. When any object vibrates it causes movement in the air. These particles bump into the particles close to them, which makes them vibrate too causing them to bump into more air particles. This movement, called waves, keeps going until they run out of energy. If your ear is within range of the vibrations, you here sound.

Explanation for Q 3:

#1 is a match with B

#2 is a match with C

#3 is a match with A

An automatic car wash takes exactly 5 minutes to wash a car. On average, 10 cars per hour arrive at the car wash. Suppose that,
77julia77 [94]

Answer:

0.9595724

Step-by-step explanation:

Time taken to wash a car (μ) = 5 minutes

Hence, Number of cars washed per hour = 60/5 = 12 cars

If 5 cars arrive, 30 minutes to closing ; it takes 25 minutes to finish up ;

If 1 more car arrives, then it takes exactly 30 minutes

Hence, there will be no one in line at closing ;

IF 0 or 1 car arrives, if more than 1 car arrives, then there will be people in line at closing.

Hence, probability of waiting in line at closing :

1 - [p(0) + p(1)]

Using poisson :

P(x) = [(e^-μ) * (μ^x)] / x!

If x = 0

P(0) = [(e^-5) * (5^0)] / 0!

P(0) = (0.0067379 * 1) / 1

P(0) = 0.0067379

X = 1

P(1) = [(e^-5) * (5^1)] / 1!

P(0) = (0.0067379 * 5) / 1

P(0) = 0.0336897

Hence,

1 - (0.0067379 + 0.0336897)

1 - 0.0404276

= 0.9595724

Hence, the probability that anyone would be in the car washing line after closing is 0.9595724
