Is a diameter of 9cm more than a radius of 5cm and which would have the larger circumference?

Mathematics

Answer:

Circle B

3.14 cm

Step-by-step explanation:

1. The diameter is twice the radius, so the diameter of Circle B is ...

 2 × 5 cm = 10 cm

This diameter is greater than the 9 cm diameter of Circle A, so Circle B is larger and will have a larger circumference.

2. The circumference is the product of π and the diameter. Then the difference between the two circumferences is ...

... (circle B circumference) - (circle A circumference) = π·(10 cm) - π·(9 cm)

... = π·(10 -9) cm = π·1 cm ≈ 3.14 cm

This is because when you subtract a positive number it is the same as adding a negative number, and when you subtract a negative number, it iss the same as adding a positive number.

Justin is asked to solve the following system of linear equations using the elimination method.
romanna [79]

Alright, lets get started.

Justin is asked to solve the linear equations using elimination method.

By using elimination method means we have to multiply some numbers in our given equations in such a way that the co-efficient of x or y become same in both equations so that we could add or subtract them to cancel one of the term either x or y.

So, given equations are :

5x - 12 = 3

-20x + 14 y = 13

See we have 5x in first equation and -20x in second equation.

So, we try to change 5x into 20 x by multiplying it with 4, both of the equations will have 20 x in common

Lets multiply 4 in first equation

4 * (5x-12y) = 4 * 3

20x - 48y = 12

Now both equations could be added and 20 x will be cancelled out and we could easily find the value of y then solve for x.

So, Justin should try to change 5 so that it will be cancels, so option B  :  Answer

Hope it will help :)

The first one  is the last answer because you subtract 18 and when you divide you change the inequality symbol 

the second one is the last answer for the same reason 

the 3rd one is x<-1.25

the 4th one is x<8/15

Point T is at (-3, 8). What are the coordinates of T' after R(y-axis) o R(x-axis)?
Whitepunk [10]

Given:

Point is T(-3,8).

To find:

The coordinates of T' after R(y-axis)\circ R(x-axis).

Solution:

We know that, R(y-axis)\circ R(x-axis) means the figure reflected across the x-axis then reflected across y-axis.

If a figure reflected across x-axis, then

(x,y)\to (x,-y)

T(-3,8)\to T_1(-3,-8)

If a figure reflected across y-axis, then

(x,y)\to (-x,y)

T_1(-3,-8)\to T'(-(-3),-8)

T_1(-3,-8)\to T'(3,-8)

Therefore, the required point is T'(3,-8).
