Answer 1

Answer:

y = 4x

Step-by-step explanation:

y and x meet at (4,1).

(4-0)/(1-0) = 4/1, = 4.

y = 4x

you can prove that the constant proportionality is 4 by looking at the next point, (8,2)

(4,1) to (8,2) is constant.

Answer 2

The answer is y=4x

Use a number line to order the numbers from least to greatest.

Answers

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

9/4=2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Vicente and Carla each ran 8 laps around a track. They started at the same time and place. If Vicente ran 1.5 times as fast as Carla, how many laps did Carla have left to finish when Vicente finished his 8th lap?

Answers

Answer:

Step-by-step explanation:

She is going half the speed as him, so she will have four laps left.

The distance left in 8 laps for Carla when Vicente has already finished his 8th lap is 2 2/3 laps.

What is speed?

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

Speed = Distance Covered / Time taken

Let the distance of a single lap be x units. Also, the time it takes for Carla to complete a single round is represented by y.

Speed of Carla = x/t

Speed of Vicente = 1.5(x/t)

Now, the time it will take Vincente to complete the 8 laps is,

Time = 8x / [1.5(x/t)]

Time = 8tx / 1.5x

Time = 16t/3

Distance covered by Carla by the time Vincente completed 8 laps,

Distance = Speed × Time

= (x/t) × (16t/3)

= 16x / 3

Now, the distance left in 8 laps is,

Distance left in 8 laps = Total distance - Distance covered

= 8x - (16x/3)

= (24x - 16x)/3

= 8x / 3

= 2 2/3 x

= 2 2/3 laps

Hence, the distance left in 8 laps for Carla when Vicente has already finished his 8th lap is 2 2/3 laps.

Sula designs greeting cards for her friends. Each friend has a 30% chance to get a musical greeting card. Design a simulation that can be used to estimate the probability that a friend will receive a musical greeting card.

Answers

Sure, I can help you create a simulation to estimate the probability of a friend receiving a musical greeting card.

Here's a simple Python code that simulates the process:

```python
import random

num_friends = 1000 # the number of friends

num_musical_cards = 0 # the number of friends who received musical cards

# simulate the card distribution for each friend
for friend in range(num_friends):
if random.random() < 0.3:
num_musical_cards += 1

# calculate the probability of a friend receiving a musical card
prob = num_musical_cards / num_friends

print("Probability of a friend receiving a musical card:", prob)
```

In this simulation, we create a loop that simulates the card distribution for each friend. We randomly assign a musical card to each friend with a 30% chance. Then, we calculate the probability of a friend receiving a musical card by dividing the number of friends who received musical cards by the total number of friends.

You can adjust the `num_friends` and `random.random() < 0.3` parameters to match your specific scenario.

What is the greatest number less than 400 such that 4 is the greatest common divisor of the number and 24?

Answers

Answer:

its simple greatest number less that 400 is 399

Answer:

388

Step-by-step explanation:

Definition from Wikipedia

In mathematics, the greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted as gcd(x,y) . For example, the GCD of 8 and 12 is 4, that is, gcd(8,4)=4 (https://en.wikipedia.org/wiki/Greatest_common_divisor)

Methodology to find greatest common denominator(factor) for 2 numbers

Write down the divisors of both numbersCollect the common divisors of both termsChoose the largest divisor from the above termsThe divisors of 24 are 1, 2, 3, 4, 6, 8, 12, 24Since the number is less than 400, it must be 4 x D where D < 100Let's try 4 x 99 = 396. Divisors are 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396. gcd(24, 396) = 12.Try D = 98 ==> 4 x 98 = 392 with divisors 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392. gcd(24, 392) = 8Try D = 97 ==> 4 x 97 = 388. Divisors of 388 are 1, 2, 4, 97, 194, 388 gcd(4, 388) = 4

Note that even though I have listed all divisors of the higher number, you don't have to compute all divisors. You can stop figuring out the divisors once the larger number is divisible by the number that is higher than 4 but slosest to i. For example, in the case of 396, I would stop computing as soon as I found it is divisible by 6

∠1 and ∠5 are ___ angles. (same options as first one)

Answers

Answer:

∠1 and ∠2 are supplementary angles.

∠6 and ∠8 are vertical angles

∠1 and ∠5 are corresponding angles.

Step-by-step explanation:

∠1 and ∠2 lie on a straight line which will always add up to 180 degrees or supplementary.

∠6 and ∠8 lie opposite each other on the transversal (intersecting line) and are equal.

<1 and <2 are Supplementary angles

<1 and <5 are Corresponding angles

<6 and <8 are Vertical angles

Given that d II e

when a transversal intersects two parallel lines the following conditions are true:

Supplementary angles are those angles when the sum of two angles is equal to 180 degrees. Since <1 and <2 are on either side of the transversal their sum is equal to 180 degrees hence why it's a supplementary angle.

Vertical angles form 4 angles when a line intersects them and the two angles are opposite to each other. In this case <6 and <8 are opposite each other hence why they are vertical angles.

Corresponding angles are the angles that are in the same position on each of the parallel lines and on the same side of the transversal. In this case both <1 and <5 are on the same side of the transversal on each of the parallel lines hence why they are corresponding angles
