The ratio of the length to width of a rectangle is 3:4 the perimeter is 56 in, find the length and the width

Verizon [17]

Answer: Length is 12in and width is 16in

Let's use the ratio method!

3+3+4+4 is 14

Let's think the length as," L " and the width as," W "

L / 56 = 3/14

L = 3/14 * 56

L = 12

And for width:

W / 56 = 4/14

W =4/14 * 56

W = 16

There you go! We did it!

A conjecture and the flowchart proof used to prove the conjecture are shown.

pishuonlain [190]

Answer:

∠1 is supplementary to ∠3.

Step-by-step explanation:

Given information: ABCD is a parallelogram.

Prove: ∠1 is supplementary to ∠3.

Proof:

∠1 = ∠ADB

∠2 = ∠DBC

∠3 = exterior angle adjacent to angle D B C.

Statement Reason

∠2 is supplementary to ∠3 Linear pairs

m∠2+m∠3=180° Definition of supplementary angles

$m\angle 1=m\angle 2$ Alternative interior angles

m∠1+m∠3=180° Substitute property of equality

∠1 is supplementary to ∠3 Definition of supplementary angles

Hence proved.

I NEED HELP PLEASE ITS A SOLVE FOR X PROBLEM :(

Varvara68 [4.7K]

Answer:

x = 4

Step-by-step explanation:

6(6 + x) = 5(5 + x + 3) => secant secant theorem

36 + 6x = 5(8 + x)

36 + 6x = 40 + 5x

Subtract 36 from each side

36 + 6x - 36 = 40 + 5x - 36

6x = 4 + 5x

Subtract 5x from each side

6x - 5x = 4 + 5x - 5x

x = 4

The value of x that satisfies the equation 4/3=x+10/15

kenny6666 [7]

For this case we must find the value of "x" that meets the following equation:

$\frac {4} {3} = x + \frac {10} {15}$

We subtract $\frac {10} {15}$ on both sides of the equation:

$\frac {4} {3} - \frac {10} {15} = x\\\frac {15 * 4-3 * 10} {3 * 15} = x\\\frac {60-30} {45} = x\\- \frac {30} {45} = x$

We simplify:

$x =\frac {6} {9}=\frac{2}{3}$

Finally, $x =\frac {2} {3}$

Answer:

$x =\frac {2} {3}$
