12.95x8%=1.036

12.95+1.036=13.986


13.986x4=55.94-10%=

$50.3496

When x+2 = 1/5y is written in standard form, what is the value or B
Ket [755]

Answer:

B=-1

Step-by-step explanation:

Standard form is Ax+By=C.

In this case, Ax is x, By is 1/5y, and C is +2.

To isolate the 2 (the C), subtract x from both sides of the equation:

x+2=1/5y

-x     -x

2=-x+1/5y.

Now, the value of B, the x value, is -1.

Please help! It is Geometry
djyliett [7]

Answer:

X=20; pqr = 130°

Step-by-step explanation:

They key here is to notice that the instructions say that qs bisects pqr, meaning that it evenly cuts it into 2 pieces. So, to find x, you just solve for x in the equation 3x+5=2x+25. Then, you plug it back into either side of the equation, at which point, you should get 65. Since it is half of pqr, just double it to get your final answer of 130°

What is the volume of a cylinder in cubic feet with a height of 8 feet and a base diameter of 18 feet
postnew [5]

Answer:

The volume of a cylinder:

V \approx 2035.75 ft^3

Step-by-step explanation:

-To find the volume of a cylinder, you first need the formula:

V = \pi (\frac{d}{2})^2  h

d = diameter

h = height

-Use the following diameter and height for the formula:

V = \pi (\frac{18}{2})^2  8

-Then, you solve:

V = \pi (\frac{18}{2})^2  8

V = \pi \times (\frac{18}{2})^2 \times  8

V = \pi \times (9)^2 \times  8

V = \pi \times 81 \times  8

V = \pi \times 648

V = 648\pi \approx 2035.752

-Since the hundredth place is 2, It cannot be rounded to the nearest hundredths place, so it would be:

V \approx 2035.75 ft^3
