What is the measure of 3?

mafiozo [28]

Answer:

∠3 = 60°

Step-by-step explanation:

Since g and h are parallel lines then

∠1 and ∠2 are same side interior angles and are supplementary, hence

4x + 36 +3x - 3 = 180

7x + 33 = 180 ( subtract 33 from both sides )

7x = 147 ( divide both sides by 7 )

x = 21

Thus ∠2 = (3 × 21) - 3 = 63 - 3 = 60°

∠ 2 and ∠3 are alternate angles and congruent, hence

∠3 = 60°

How many inches around is the crust if the diameter of the pizza is 8 inches?

I am Lyosha [343]

Hi there!

Here, we're looking for the circumference. The formula for the circumference of a circle is pi x diameter. Using this formula, we can figure out the circumference.

WORK:
C = pi x 8
C = 8pi
or 25.13 in

Hope this helps!! :)

The right end of a relaxed standard spring is at the origin; the left end is clamped at some point on the negative x-axis. Holdi

ella [17]

The work required to stretch the spring is 350J.

<h3>Hooke's Law</h3>

This law can be written by the formula: F=kx, where:

F= elastic force (N)

k= spring constant (N/m)

x= linear displacement (m)

<h3>Spring Work</h3>

For finding the spring work in J, you should apply the formula $W=\frac{k*(\Delta x)^2}{2}$ , where:

W= work (J)

k= spring constant (N/m)

x= difference between the linear displacements (m)

The question gives:

x=5 cm=0.05m requires a force of 1.4N

x=8 cm =0.08m

Step 1 - First, you should find the spring constant from Hooke's law, for x=5 cm and F=1.4N.

$F=kx\\ 1.4=k*0.05\\ \\ k=\frac{1.4}{0.05} =28\frac{N}{m}$

Step 2 - Now you can apply the formula for spring work.

$W=\frac{k*(\Delta x)^2}{2}\\ \\ W=\frac{28*(8-3)^2}{2} \\ \\ W=\frac{28*(5)^2}{2}\\ \\ W=\frac{28*25}{2}\\ \\ W=\frac{700}{2}=350J$
