If ef bisects angle ceb,angle cef=7x+31 and angle feb=10x-3

Nastasia [14]

Given : Angle < CEB is bisected by EF.

< CEF = 7x +31.

< FEB = 10x-3.

We need to find the values of x and measure of < FEB, < CEF and < CEB.

Solution: Angle < CEB is bisected into two angles < FEB and < CEF.

Therefore, < FEB = < CEF.

Substituting the values of < FEB and < CEF, we get

10x -3 = 7x +31

Adding 3 on both sides, we get

10x -3+3 = 7x +31+3.

10x = 7x + 34

Subtracting 7x from both sides, we get

10x-7x = 7x-7x +34.

3x = 34.

Dividing both sides by 3, we get

x= 11.33.

Plugging value of x=11.33 in < CEF = 7x +31.

We get

< CEF = 7(11.33) +31 = 79.33+31 = 110.33.

< FEB = < CEF = 110.33 approximately

< CEB = < FEB + < CEF = 110.33 +110.33 = 220.66 approximately

The price of a refrigerator at Best Buy is $4,299.00. Best Buy is offering a $900 instant discount. There is also a $100 instant

stiks02 [169]

Answer:

$Final\ Price = \$ 3299.00$

Step-by-step explanation:

Given

$Original\ Price =\$4299.00$

$Discount = \$900$

$Rebate = \$100$

Required

Determine the final price

If all discounts are taken, the final price is:

$Final\ Price = Original\ Price - Discount -Rebate$

This gives:

$Final\ Price = \$ 4299.00 - \$900 - \$100$

$Final\ Price = \$ 3299.00$

Is it possible for the perimeter of a figure to change after its reflected?

ch4aika [34]

No, reflections do not chage shape, size or area. The only transformation that does that is dilation.

A paper clip is dropped from the top of a 144‐ft tower, with an initial velocity of 16 ft/sec. Its position function is s(t) = −

BabaBlast [244]

$\bf s(t)=-16t^2+144\implies \stackrel{velocity}{\cfrac{ds}{dt}}=-32t$

when does it hit the ground? check the picture below.

$\bf 0=-16t^2+144\implies 16t^2=144\implies t^2=\cfrac{144}{16}\implies t^2=9
\\\\\\
t=\sqrt{9}\implies t=3$

at that moment, the velocity is -32(3).
