Julia left school and travel toward the train station. One hour later Carlos left traveling at 30 mph in an effort to catch up to Julia. After traveling for two hours Carlos finally caught up. Find Julie is average speed

Answers

speed = distance/time

distance = speed * time

Carlos traveled for 2 hours.
Julia traveled for 1 more hour, or 3 hours

Carlos:
time = 2
distance = d
speed = 30 mph

distance = speed * time
d = 30 * 2
d = 60 miles

They both traveled 60 miles.

Julia:
time = 3
distance = 60 miles
speed = s

speed = distance/time = (60 miles)/(3 hours) = 20 mph

Julia's speed is 20 mph.

find the percent increase for 13 friends to 14 friends round to nearest percent if you can

Answers

From 13 to 14 # is increased by 1

14-14 = 1/13 *100% That equals 7.69%

Your answer is 7.69%

Final answer:

The percent increase from 13 to 14 friends is calculated as [(14 - 13) / 13] × 100, which gives a result of approximately 7.7%. After rounding to the nearest percent, the increase is 8%.

Explanation:

To find the percent increase from 13 friends to 14 friends, we use the formula for percentage change, which is:

Percentage Change = [(New Value - Original Value) / Original Value] × 100

In this case, our original value is 13 (the number of friends at the start) and our new value is 14 (the number of friends after the increase). So, we plug these numbers into our formula:

Percentage Change = [(14 - 13) / 13] × 100 = [1 / 13] × 100

Now, we calculate the fraction and then multiply by 100:

Percentage Change = (0.07692307692) × 100 ≈ 7.7%

When rounded to the nearest percent, the percent increase is approximately 8%.

mr smith waters one one of his plants every 10 days and another plant every 14 days. If he water both days today when is the next time both plants will be watered on the same day?.

Answers

it will be after 70 days

Answer:

after 70 days.

Step-by-step explanation:

Mr. Smith waters one of his plants every 10 days and another plant ever 14 days.

he waters both plants today we have to find the next time both plants will be watered on the same day.

So we will take LCM of these numbers.

LCM of 10 , 14

= 2 × 5 × 7

= 70

The next time both plants will be watered on the same day after 70 days.

Step-by-step explanation:

We are given a information as:

Samuel recorded the number of different types of pets his friends have in the table shown below:

Cats 5

Dogs 3

Rabbits 1

Guinea Pigs 3

The plot based on this information will be:

A line with 4 tick marks labeled Cat, Dog, Rabbit, and Guinea Pig. Cat has 5 crosses ( since it is observed that there were 5 cats) , Dog has 3 crosses, Rabbit has 1 cross, and Guinea Pig has 3 crosses. The line is labeled Number of Pets, and title of graph is Pet Owners.

Hence, option: C is correct.

estimate 102.3 divided by 4.7

Answers

Answer:

20

Explanation:

To estimate, we round.  102.3 rounds to 100 and 4.7 rounds to 5; this means we divide 100/5, which is 20.

Answer:

The estimate result of 102.3 divided by 4.7 is 20.

Step-by-step explanation:

Given : 102.3 divided by 4.7

We have to estimate 102.3 divided by 4.7

Since, estimation is the roughly calculation and is usually involves rounding to the nearest values so that they are easy to cancel out.

Since, we have to divide,

102.3 divided by 4.7

Rounding 102.7 to nearest tens place , we get, 102. 7 = 100

And Rounding 4.7 to nearest  ones place, we get, 4.7 = 5

Thus, when divide 100 by 5 , we get 20.

Thus,  102.3 divided by 4.7 ≈ 20

Thus, The estimate result of 102.3 divided by 4.7 is 20.

Which graph represents the function f(x) = −|x − 2| − 1?

Answers

the 3rd one in the picture

Answer:

option 3

Step-by-step explanation:

[tex]f(x) = -|x -2| - 1[/tex]

The given equation is in the form of [tex]f(x) = a|x -h|+k[/tex]

where (h,k) is the vertex .

[tex]f(x) = -|x -2| - 1[/tex]

h=2 and k=-1 . the value of a=-1

Since the value of 'a' is negative so the graph will be upside down

option 3 is upside down and vertex at (2,-1)

So option 3 graph represents the function

what is a solution to (x-2)(x+10)=13?
a: x=3
b: x=8
c: x=10
d: x=11

Answers

(x-2)(x+10)=13

x^2 + 10x - 2x - 20 = 13

x^2 + 8x - 20 - 13 = 0

x ^2 + 8x - 33 = 0

(x + 11) (x - 3) = 0

x + 11 = 0

x = -11

x - 3 = 0

x = 3
