A Car Travels At A Constant Speed. What Is The Car's Speed Between Checkpoints, Expressed As A Unit Rate?

Answers

Answer 1
44 mph

208-120= 88
88/2 = 44
Answer 2

Answer:

The unit rate is 44 miles per hour.

Step-by-step explanation:

The difference between both the checkpoints is given by:

[tex]208-120=88[/tex] miles driven

Time taken to travel 88 miles = [tex]3-1=2[/tex] hours

As the car travels at a constant speed, so we get 88 miles driven in 2 hours.

Hence, per hour distance covered is = [tex]\frac{88}{2}=44[/tex] miles per hour.

Since cc is on the right side of the equation, switch the sides so it is on the left side of the equation.6(2c−12)−4c=8(c−9)6(2c-12)-4c=8(c-9)Simplify the left side.8c−72=8(c−9)8c-72=8(c-9)Simplify the right side.8c−72=8c−728c-72=8c-72Move all terms containing cc to the left side of the equation..−72=−72-72=-72Since −72=−72-72=-72, the equation will always be true.Always true
On the left side of the equal sign, multiply everything in the parenthesis by 8.
On the right side of the equal sign, multiply everything in the parenthesis by 6.

8c - 72 = 12c - 72 - 4c

Combine like terms.

8c - 72 = 8c - 72

Add 72 to both sides.

8c = 8c

Subtract 8c from both sides.

0 = 0

This means that there is an infinite amount of solutions.

The drama club is selling short-sleeved shirts for $5 each, and long-sleeved shirts for $10 each. They hope to sell all of the shirts they ordered, to earn a total of $1,750. After the first week of the fundraiser, they sold  1/3 of the short-sleeved shirts and  1/2of the long-sleeved shirts, for a total of 100 shirts.
This system of equations models the situation.
   5x + 10y = 1,750
1/3x + 1/2y = 100
Let x represent the number of short-sleeved shirts ordered and let y represent the number of long-sleeved shirts ordered.
How many short-sleeved shirts were ordered?

How many long-sleeved shirts were ordered?

Answers

150 short-sleeved shirts
100 long-sleeved shirts

Answer:

150 short-sleeved shirts and 100 long-sleeved shirts.

Step-by-step explanation:

We will use elimination to solve this system of equations.  We will make the coefficients of x the same in order to eliminate them; to do this, we must multiply the bottom equation by 15 (1/3 of 15 is 5, so 15(1/3) = 5):

[tex]\left \{ {{5x+10y=1750} \atop {15(\frac{1}{3}x+\frac{1}{2}y=100)} \right. \\\\\left \{ {{5x+10y=1750} \atop {5x+7.5y=1500}} \right.[/tex]

Subtract the second equation from the first one:

[tex]\left \{ {{5x+10y=1750} \atop {-(5x+7.5y=1500)}} \right. \\\\2.5y=250[/tex]

Divide both sides by 2.5:

2.5y/2.5 = 250/2.5

y = 100

Substitute 100 in for y in the first equation:

5x+10(100) = 1750

5x+1000 = 1750

Subtract 1000 from both sides:

5x+1000 - 1000 = 1750 - 1000

5x = 750

Divide both sides by 5:

5x/5 = 750/5

x = 150

A card is drawn from a standard deck and a letter is chosen from the word incredible. What is the probability of drawing a king then getting an i?

Answers

There is a 4/52 chance of getting a king, because there are 52 cards in a deck, and 4 kings in each. And there is a 2/10 (1/5) chance of getting an i, because there are 2 i's in the word "incredible", and 10 letters (so simplifying that, you would get 1/5).

Step-by-step explanation:

A card is drawn from a standard deck. A standard deck of cards has 52 cards. Its been asked if it is a king. There are 4 kings in a deck, so probability is = [tex]\frac{4}{52}[/tex] or [tex]\frac{1}{13}[/tex]

Simultaneously, a word is chosen from 'incredible' that has 10 letters. We have been asked if the letter is 'i'. In the given word, we have 2 'i's. So, probability is [tex]\frac{2}{10}[/tex] or [tex]\frac{1}{5}[/tex]

40 pounds of sugar are repackaged of 1/16 pounds each. how many packet of sugar are there?

Answers

We know to each pound of such, there is 16 packets produced per?

So, 16 x 40 = 640.

Final answer:

To find the number of sugar packets from 40 pounds, divide by the weight per packet (1/16 pound). The calculation is 40 divided by 1/16, resulting in 640 packets.

Explanation:

To determine how many packets of sugar you can make from 40 pounds of sugar when each packet is 1/16 pounds, you would divide the total amount of sugar by the amount each packet contains. This is a basic math problem involving division.

Here's the calculation:

First, we establish that there are 40 pounds of sugar that need to be divided into packets.

Next, since each packet will contain 1/16 of a pound of sugar, we divide the total pounds of sugar by the weight of each packet.

The calculation is 40 pounds \/ (1/16) pounds per packet, which simplifies to 40 × 16 packets.

After performing the multiplication, the result is 640 packets of sugar.

Therefore, you would have a total of 640 packets of sugar if you repackage 40 pounds of sugar into 1/16 pound packets.

The library has 2,000 books for sale.The books are sorted into nonfiction, fiction, and children's books. The children's books number 500.

Answers

If you take 2000 and subtract that by 500 for the childrens books that would equal 1500. So, the fiction and nonfiction books sum would have to be 1500. Since 850 plus 650 equals 1500, there would be 650 nonfiction books, 850 fiction books, and 500 children's books.

You are setting up a zip line in your yard. You map out your yard in a coordinate plane. An equation of the line representing the zip line is y=2x+4y=2x+4. There is a tree in your yard at the point (−4, 11)(−4, 11). Each unit in the coordinate plane represents 1 foot. Approximately how far away is the tree from the zip line? Round your answer to the nearest tenth.

Answers

Solving this problem needs the distance formula of point to a line.

The formula is:

distance = | a x + b y + c | / √  (a^2 + b^2)

 
So we are given the equation: y = 2 x + 4

Rewriting this would be: y – 2 x – 4 = 0 ->  a = -2, b = 1, c = -4

 We are also given the points:

(-4, 11) = (x, y)

 Plugging it in the distance formula at points (x, y):

distance = | -2 * -4 + 1 * 11 + -4 | / √ [(- 2)^2 + (1)^2]

= 15 / √ (5)

= 6.7

 So the tree is approximately 6.7 feet away from the zip line.

Joesl's father is 45. He is 15 years older than twice joe's age. How old Is joe?

Answers

Joe father is 45

Joe father is 2x + 15

2x + 15 = 45
2x + 15 (-15) = 45 (-15)
2x = 30
2x/2 = 30/2
x = 15

Joe is 15

hope this helps
So, you make your equation 2x+15=45, because of the given numbers. Now you solve for x.
First, you subtract 15 from both sides, which gives you 2x=30.
Then you divide both sides by 2, which give you x=15.
So, Joe is 15 years old.
