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%.

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.

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.

What is the question

Marty has a fenced yard in the shape of a rectangle. It's area is 635.4 square feet. The width of the yard is 18 feet. What is the length of the fence?

Answers

Area=length*width

635.4=18*L
35.3=L

So the answer is 35.3
Final answer:

The length of the rectangular yard, given an area of 635.4 square feet and a width of 18 feet, can be calculated using the formula for the area of a rectangle. Substituting the given values into the formula, we find that the length is approximately 35.3 feet.

Explanation:

The question is about finding the length of a rectangular yard given its area and width. Recognizing that the formula for the area of a rectangle is Area = Length x Width, we can easily find the length of the yard by rearranging the formula.

To find the length of a rectangle when you know the area and width, use the rearranged area formula: Length = Area ÷ Width.

Given the values from the problem: Area = 635.4 sq ft and Width = 18 ft, we substitute them into the formula: Length = 635.4 ÷ 18. This results in a length of approximately 35.3 feet.

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

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

Answers

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)

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the rounded number be represented as A

Let the number be represented as n

Now , the value of n = 1.75

And , when you round to the nearest ones place. The 1 in the ones place rounds up to 2 because the digit to the right in the tenths place is 7.

When the digit to the right is 5 or greater we round away from 0.

So , the rounded number is A = 2
