An oak tree is 1.5 x 10^3 centimeters tall which unit of measurement is most appropriate to measure this height

Rashid [163]

D) feet

A tree 1.5 x 10^3 is 1500 centimeters. That's about 300 inches, which would better be measured in feet.

find the value of the polygon. the polygon has 6 interior angles 2 of them are y and 4 of them are (2Y-20)

Anna35 [415]

First we need to determine what the 6 angles must add to. Turns out we use this formula

S = 180(n-2)

where S is the sum of the angles (result of adding them all up) and n is the number of sides. In this case, n = 6. So let's plug that in to get

S = 180(n-2)
S = 180(6-2)
S = 180(4)
S = 720

The six angles, whatever they are individually, add to 720 degrees. The six angles are y, y, 2y-20, 2y-20, 2y-20, 2y-20, 

They add up and must be equal to 720, so let's set up the equation to get...

(y)+(y)+(2y-20)+(2y-20)+(2y-20)+(2y-20) = 720

Let's solve for y

y+y+2y-20+2y-20+2y-20+2y-20 = 720

10y-80 = 720

10y-80+80 = 720+80

10y = 800

10y/10 = 800/10

y = 80

Now that we know the value of y, we can figure out the six angles

angle1 = y = 80 degrees
angle2 = y = 80 degrees
angle3 = 2y-20 = 2*80-20 = 140 degrees
angle4 = 2y-20 = 2*80-20 = 140 degrees
angle5 = 2y-20 = 2*80-20 = 140 degrees
angle6 = 2y-20 = 2*80-20 = 140 degrees

and that's all there is to it

Alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip. Which expression represents the total amount that Alexi

defon

Answer:

The expression represents the total amount that Alexi needs to pay is T= 1.02A , where T is total amount and A is restaurant bill.

Step-by-step explanation:

Given : Alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip.

We have to find the expression represents the total amount that Alexi needs to pay.

Since, Alexi's restaurant bill is $ 58.

Also, she want to leave 20 % tip

So 20 % of her restaurant bill is 20% of 58

$\frac{20}{100}\times 58=11.6$

Thus, her total amount is 58 + 11.6 = $ 69.6

Alos, in expression it can be represented by

Total Amount to be paid = Amount + 0.02(Amount)

Mathematically, written as

T = A+ 0.20A

T= (1+0.02)A

T= 1.02A

The expression represents the total amount that Alexi needs to pay is T= 1.02A , where T is total amount and A is restaurant bill.
