Power Walking has been at the top of a natural range to walk with such a speed. A walk defines as a walking journey, and the further discussion can be defined as follows:

Given:

Power walking by the Gabriella by every 3 days  

Walking by the Mona by every 5 days  

Both walk on Monday then They both walked together,

after taking LCM of 5 and 3 that is = 15 days

For question a:

Let the number of students be x,

Now,

7% of x = 1400

or, 7/100 X x = 1400

or, x = 1400 x 100

—————

Answer:

3/5 Choice 4.

Step-by-step explanation:

Remember SOH, CAH, TOA.

Sine=opposite/hypotenuse

Cosine=Adjacent/hypotenuse

Tangent=Opposite/adjacent.

Since we are looking for Cosine, we would need to locate the adjacent and hypotenuse of angle a.

The hypotenuse is the easiest to find because that will simply be the longest side of the triangle(50)

The adjacent would be 30 because 40 is the opposite(right across from theta).

So, A=30

H=50

Simply that to get Cos(A)=[tex]\frac{3}{5}[/tex].

5) 6/11

6) 2/7

Answer:

You have the formula wrong.

The volume of a cylinder = PI * radius^2 * height

To find the height, the formula is:

height = volume / (PI*radius^2)

I'm assuming the radius = .6 meters so

height = 720 / (3.14159265 * .6^2)

height = 720 / 1.130973354

height = 636.61977 meters

Hi! I'm happy to help!

Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)

2,000×4

8,000

8,000/5

Fractions are just a different way of putting division, so we can change this to a division problem:

8,000÷5=

1,600

1,600 of the people are middle class.

The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.

The given percentage are,

8%, 15%, and 20%.

Now to find the overall average increase we need to find the average percentage for three consecutive years.

overall average = sum of all the percentage/number of percentage

overall average =  8%+15%+ 20%/3

overall average =  43%/3

overall average =  14.33%

Hence,The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

Answer:

1/2 = r

Step-by-step explanation:

7r + 21 = 49r

Subtract 7r from each side

7r-7r + 21 = 49r-7r

21 = 42r

Divide each side by 2

21/42 = 42r/42

1/2 = r

Answer:

r = 0.5

Step-by-step explanation:

First you need to isolate the r variable.

7r + 21 = 49r

-7r          -7r

21 = 42r

Then Divide both sides by 42

0.5 = r

Now check your answer by inserting it back into the original equation.

7(0.5) + 21 = 49(0.5)

3.5 + 21 = 24.5

24.5 = 24.5

The equation is true so r = 0.5

There are two statements here, showing quantities in real world which are additive inverse of each other :

2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.

here, we can depict going up as +2 miles and going down the trail as -2

4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.

And here we can assume going up the ground aa + 2000 ft and going down aa - 2000 ft .

Answer:

The options are (2) and (4).

Step-by-step explanation:

2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.

→ Up 2 mi (+2) and down 2 mi (-2).

4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.

→ Here they are, ascends 2000 ft (+2000) and descends 2000 ft (-2000).

Answer:

using phythagoras formula of right angles we can calculate the hypotenuse

1^2=x^2+17^2

x^2=17^2-1^2(transpose)

×^2=288 (introduce a square root)

x=15.01(round of to the nearest tenth)

Step-by-step explanation:

x=10

The measure of the hypotenuse is 17.029

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have Pythagoras theorem:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Given;

The legs of a right triangle measures 1 cm

The other leg measures 17 cm

Now,

|AC|^2 = |AB|^2 + |BC|^2    

|AC|^2 = |1|^2 + |17|^2    

|AC|^2 = 1 + 289

AC=17.029

Therefore, by pythagoras theorem answer will be 17.029.

Answer:

m = -1/2

Step-by-step explanation:

4 − 2 = 12

= −2 = 12 − 4

= = (12 − 4) ÷ (−2)

= = 2−6

So, the slope is 2.

Now, keep this rule in mind: the product of a slope of two perpendicular lines will be -1.

Thus, the slope of the line that is perpendicular to this line is -1/2
