irinina [24]3 years ago
6 0

Answer:

Equation: 10x-12=6x-6

X: 3/2 or .5

Perimeter of square and triangle are both 3.

Step-by-step explanation:

Square:

4(2.5x-3) {The four represents the amount of sides}=

10x-12

Triangle:

3(2x-2)=

6x-6

Since they have the same perimeter the equation is

10x-12=6x-6

10x-6x=12-6

4x=6

x=1.5

Square pt 2:

4(2.5(3/2)-3)=

4(3.75-3)=

4(0.75)=

3

Triangle pt 2:

3(2(3/2)-2)=

3(3-2)=

3(1)=

3

two wheels are rolled simultaneously. The radius of the smaller wheel is r feet and the radius of the larger wheel 2r feet. If b
Nuetrik [128]
The circumference of a circle is C=2πR, where R is the radius of the circle and π≈3.14.

So if we open the circumference of the circle into a straight line segment, the length of this segment is C=2πR≈2*3.14*R=6.28R

4 rotations mean 4 circumferences that is 4 segments of length 6.28R, 
which makes a linear distance of 4*6.28R=25.12R


i: the radius of the smaller wheel is R=r, thus it covers a distance of 25.12r feet

ii: the radius of the smaller wheel is R=2r, thus it covers a distance of  25.12*2r=50.24r (feet)

50.24r is twice 25.12r, thus the larger wheel traveled Twice the distance of the smaller one.


Answer: the larger covered twice the distance of the smaller.

Solve for x in the diagram below
ella [17]

Answer:

20

Step-by-step explanation:

3x + x + 100 = 180 (sum of angles on a straight line)

4x = 180-100

4x=80

divide both sides by 4

x=20

Determining the input using an equation f (x) = -1/3x + 7
daser333 [38]

Answer:

19

Step-by-step explanation:

f(x)=2/3

2/3=-1/3x+7

Subtract 7 from both sides

2/3-7=-1/3x

-6 1/3 = -1/3x

Multiply both sides by -3

-3(-6 1/3)=-1/3x(-3)

19 = x
