Answer:

17 meters

Step-by-step explanation:

the circumference is solved by multiplying the diameter by pi.

the diameter can be found by multiplying the raduis by 2

the diameter is 5.4

5.4 x 3.14

16.956

about 17 meters

Answer:

17[tex]m^{2}[/tex]

Step-by-step explanation:

The cirfumference of a circle when given the radius is 2πr

So pi is 3.14 thus:

2 × 3.14 × 2.7

16.956 [tex]m^{2}[/tex]

When rounding of to the nearest meter check if the number in the tenths side is bigger than 5. It is bigger so we add 1 to the units making it 17[tex]m^{2}[/tex].

Answer:

Leon will post 2 science club flyers in each location

Leon will post 3 music club flyers in each location

The greatest number of locations that Leon can post at is 6 locations

Step-by-step explanation:

Science club flyers = 12

Music club flyers = 18

He wants to make sure that no flyers are left over.

Find the highest common factor of 12 and 18

12 = 1, 2, 3, 4, 6 and 12

18 = 1, 2, 3, 6, 9 and 18

The highest common factor of 12 and 18 is 6

The greatest number of locations that Leon can post at is 6 locations

Science club flyers = 12

= 12 / 6

= 2

Leon will post 2 science club flyers in each location

Music club flyers = 18

= 18 / 6

= 3

Leon will post 3 music club flyers in each location

Leon will post 2 science club flyers in each location

Leon will post 3 music club flyers in each location

The greatest number of locations that Leon can post at is 6 locations

The product of 12 and 2 minus the quotient of 45 and 5 is 84.

An expression is combination of variables, numbers and operators.

we need to find  the product of 12 and 2 minus the quotient of 45 and 5

the quotient of 45 and 5, we can calculate it by dividing forty five divided by 5.

45/5 is 9

2 minus the quotient of 45 and 5

So subtract 2 from 9

9-2=7

Now  the product of 12 and 2 minus the quotient of 45 and 5.

12 is multiplied with seven

12×7

84

Hence, the product of 12 and 2 minus the quotient of 45 and 5 is 84.

Answer:

y = 1/4x - 7

Step-by-step explanation:

Slope intercept form is y=mx+b

To turn the equation into slope intercept you would have to re-arrange it making sure to do the same thing on both sides.

 x - 4y = 28

- x            -x

-4y = -x + 28

Now divide both sides by -4

y = 1/4x -7

If you have any questions let me know. Hopefully this helps and have a great day!

The equation x - 4y = 28 can be written in slope-intercept form as y = (1/4)x - 7.

Given is an equation x - 4y = 28, we need to convert this in slope-intercept form,

To convert the equation x - 4y = 28 into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, we need to isolate the variable y.

Starting with the given equation:

x - 4y = 28

We can begin by moving the x term to the other side of the equation:

-4y = -x + 28

Next, we divide both sides of the equation by -4 to isolate y:

y = (-1/-4)x + (28/-4)

Simplifying further:

y = (1/4)x - 7

Now we have the equation in slope-intercept form, with a slope of 1/4 and a y-intercept of -7.

Answer:

Dynamic equilibrium

Step-by-step explanation:

Dynamic equilibrium in the human body is achieved when there is an internal control which tends to oppose certain outside forces which could affect the body. It's known to be the ability to detect and respond to stimuli by living organisms. When these stimuli occur, there are feedbacks or responses that are sent or received by the body to maintain stability. This dynamic equilibrium of the internal environment can also be seen as homeostasis.

Answer:

add 35 and 20

Step-by-step explanation:

1) The measure of angle BAD will be 55°.

2) The measure of the angle ABC is 125°.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

1.) The angle BAD will be calculated by applying alternate exterior angle property.

The angle BAD = 35 + 20 = 55°

2). The angle ABC will be calculated by the triangle angle sum property which is the sum of all the angles of the triangle is 180°.

Angle ABC = 180 - 35 - 20 = 125°

Therefore the measure of angle BAD will be 55°. The measure of the angle ABC is 125°.
