Find the area and the circumference of a circle with a diameter of 17cm

frosja888 [35]

Answer:

Step-by-step explanation:

d = 17 cm

r = 17/2 = 8.5 cm

Circumference of circle = πd

= 3.14 * 17

= 53.38 cm

Area of circle = πr²

= 3.14 * 8.5 * 8.5

= 226.865 cm²

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 higher than in the firs

expeople1 [14]

Sorry for the delay!

Let x = charge before tax in 1st city, and y = charge before tax in 2nd city

y = $1500 + x

4/100x => tax in first city

3.5/100y => tax in second city

0.04x + 0.035y = $408.75

We have the following system of equations to solve:

$\begin{bmatrix}y=1500+x\\ 0.04x+0.035y=408.75\end{bmatrix}\\\\\mathrm{Substitute\:}y=1500+x\\\\begin{bmatrix}0.04x+0.035\left(1500+x\right)=408.75\end{bmatrix}\\\begin{bmatrix}0.075x+52.5=408.75\end{bmatrix}\\\\\ x = 4750\\\mathrm{For\:}y=1500+x\\\mathrm{Substitute\:}x=4750:\\\\y=1500+4750 = 6250$

So the hotel charge before tax in city 1 = $4750, and the hotel charge before tax in city 2 = $6250

Pls help this is due today ! Find the value x:

tensa zangetsu [6.8K]

Answer:

x= 12

Step-by-step explanation:

180° = (3x - 6) + (8x + 4) + 50° because all interior angles of a triangle add up to 180°

180° = 11x +48°

11x = 132°

x = 12

Convert 185 degrees Celsius to degrees Fahrenheit. Round your answer to the nearest degree

lakkis [162]

Hello! :3

Answer:

The Correct Answer is 365 °F

Step-by-step explanation:

The C to F formula is $(C ~x~ 9/5) + 32 = F$

When we do 185 for C in the formula, we get $(185 ~x~ 9/5) + 32 = F.$

To solve, $(185 ~x~ 9/5) + 32 = F.$ we first multiply 9 by 185, then we divide the product by 5, and then finally we add 32 to the quotient to get the answer.

$185~x~9=1665$
