The school hiking club has completed 4 out of 5 hikes so far this year. They have hiked 4.6 miles, 3.7 miles, 5.1 miles, and 2.9 miles. If their goal is to hike 20 total miles, how many miles does the last hike need to be? 4.7 miles

3.7 miles

2.7 miles

1.7 miles

Answer:

They need travel 3.7 miles to reach their goal.

Step-by-step explanation:

The total number of annual miles walked by the club corresponds to the sum of the 5 partial tours, that is:

Total Miles = 4.6 + 3.7 + 5.1 + 2.9 + X, where X represents the number of miles traveled on the last excursion. As you want to travel a total of 20 miles, you have:

Total Miles = 4.6 + 3.7 + 5.1 + 2.9 + X = 20

X = 20 - 4.6 - 3.7 - 5.1 - 2.9 [transposition of terms]

X = 3.7 miles to reach your annual 20 miles goal.

3.7 miles Add all of the previous miles together 4.6=3.7+5.1+2.9=16.3 miles subtract 16.3 miles from 20 miles this equals 3.7 miles that is your answer

What is the greatest common factor of 343, 49, and 196?

We have to find the greatest common factor of 343, 49 and 196.

The greatest common factor, or GCF, is the greatest factor that divides the given numbers.

First of all, we will find the factors of each of the number.

Now, we will find out the greatest common factors. 7 and 7 are the greatest common factors.

So, Greatest common factor =

= 49.

Therefore, 49 is the greatest number that divides the given numbers.

The greatest common factor of these numbers would be 7

Which of these numbers has the smallest value? Nine tenths, twenty hundredths, two hundredths, or forty five thousandths Which inequality correctly compares thirty five and thirty seven hundredths to thirty five and ninety four thousandths

A. 35.27 < 35.94

B. 35.27>35.094

C. 35.27>35.94

D. 35.27<35.094

Solve this 25-{2X(18 divided 6)+ 1]

Nine tenths = 0.9

Twenty hundredths is 0.2

Two hundredths is 0.02

Forty five thousandths is 0.045

The number with the smallest value is 0.02, or two hundredths.

The inequality that correctly compares thirty five and thirty seven hundredths (35.37) to thirty five and ninety four thousandths (35.094) is B. 35.37 > 35.094, because 35.37 is greater than 35.094.

25 - [2 x (18÷ 6) + 1]

25 - [2 x (3) + 1]

25 - [6 + 1]

25 - [7]

18

25 - [2 x (18 ÷ 6) + 1] = 18

Twenty hundredths is 0.2

Two hundredths is 0.02

Forty five thousandths is 0.045

The number with the smallest value is 0.02, or two hundredths.

The inequality that correctly compares thirty five and thirty seven hundredths (35.37) to thirty five and ninety four thousandths (35.094) is B. 35.37 > 35.094, because 35.37 is greater than 35.094.

25 - [2 x (18÷ 6) + 1]

25 - [2 x (3) + 1]

25 - [6 + 1]

25 - [7]

18

25 - [2 x (18 ÷ 6) + 1] = 18

Find the midpoint of the segment that connects (4,5) and (5,4(

The answer in fraction form is (9/2, 9/2), which in decimal form it would be (4.5, 4.5)

To get this answer, you add up the x coordinates of each point and divide by 2. So we'll have (4+5)/2 = 9/2 = 4.5

The same will apply to the y coordinates as well: (5+4)/2 = 9/2 = 4.5

A baker need 6lbs of butter for a recipe .She found 2 portions that each weigh 1 1/4 and a portion weight 2 3/4 does she have enough butter for recipe

Answer: The baker doesn't have enough butter.

Step-by-step explanation:

Total number of pounds of butter that the baker needs for the recipe is 6 pounds.

She found 2 portions. One of them weighs 1 1/4 pounds. Converting 1 1/4 pounds to improper fraction, it becomes 5/4 pounds.

The other portion weighs 2 3/4 pounds. Converting 2 3/4 to improper fraction, it becomes 11/4 pounds.

Total amount of butter that the baker has would be

5/4 + 11/4 = 16/4 = 4 pounds.

Therefore, the baker doesn't have enough butter.

Answer no she does not have enough:

Step-by-step explanation:

2(1.25) = 2.5

2.75

2.5+2.75 =5.25

What is the product of r^2 -3 and 2r

Answer:

- 6r³.

Step-by-step explanation:

Here, we have to find the product of r², - 3 and 2r.

Now, the product is, P = (r²)(- 3)(2r)

⇒

{Seperating each terms as the terms are in product form}

⇒

{Using the property of exponent that }

⇒ P = - 6r³ (Answer)
