Marie has a small copy of Rene margrittes famous painting. The Schoolmasters. Her copy has dimensions of 2 inches by 1.5 inches. The scale of her copy is 1 inch:40 cm What is the dimensions of the original painting?


Every 1 inch on her copy is the same as 40 cm on the original. 
You just have to multiply by 40 and convert to centimetres.

2 x 40 = 80
1.5 x 40 = 60

So the original painting is:
80cm by 60cm

What are the coordinates of B and how is that the answer ?
Trava [24]

Step-by-step explanation:

Point A = (-1, -3).

Midway of AB = (-3, 2).

Let Point B = (x, y).

Then (-1, -3) - (-3, 2) = (-3, 2) - (x, y).

=> (2, -5) = (-3-x, 2-y).

We have -3 - x = 2 and 2 - y = -5.

So x = -5 and y = 7.

Hence, point B = (-5, 7).

brooke opens a credit card with an APR of 28.99%. how much is charged in interest this month if her balance is $500?
Varvara68 [4.7K]
To find the interest accrued for the month, you will use the interest formula I = prt.  P stands for the principal (the amount of money borrowed), r is the interest rate, and t is the time period.  Because the interest rate is an annual (yearly) interest rate, you will use the fraction 1/12 in your calculation.  The math would be $500 x 0.2899 x 1/12.  This equals an interest charge of $12.08.

Anettt [7]

Answer:

x=\frac{5\pi}{4}

Step-by-step explanation:

We want to solve;

\cscx=-\sqrt{2} in the 3rd quadrant

Recall that;

\sin x=\frac{1}{\csc x}

We use the reciprocal ratio to get;

\sin x=-\frac{\sqrt{2}}{2}

In the third quadrant the solution is

x=\pi+\sin^{-1}(\frac{\sqrt{2} }{2} )

x=\pi+\frac{\pi}{4}

x=\frac{5\pi}{4}

HELP PLEASE!!! 25 Points & Brainliest!
Citrus2011 [14]

Answer:

(1) f(x)=3x+4

Ad g(x) represent f(x) after horizontal translation 2 units to the left.

g(x)=3(x+2)+4

g(x)=3x+6+4

g(x)=3x+10 is the required translation.

(2) f(x)=\frac{-2x}{3}+2

f(\frac{1}{2})=\frac{-2}{3}\cdot(\frac{1}{2})+2

f(\frac{1}{2})=\frac{5}{3}

(3) We have been given a point (1,-9); slope 2

We will use the equation:

y-y_1=m(x-x_1)

m is the give slope.

y-(-9)=2(x-1)

y+9=2(x-1)

Therefore, Option (a) is correct.
