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

Which linear function is represented by a graph with a y-intercept of −16 ? y=−16x+1 y=16x−1 y=x−16 y=x+16
Romashka [77]

Answer:

y = x - 16

Step-by-step explanation:

The <em>y-intercept</em> is the value of the function when x = 0.

If f(x) = x - 16, f(0) = 0 - 16 = -16.

A is <em>wrong</em>, because f(0) = -16(0) + 1 = 0 + 1 = 1.

B is <em>wrong</em>, because f(0) =  16(0) + 1 = 0 + 1 = 1.

D is <em>wrong</em>, because f(0) =     0 + 16 = 16.

Can someone help me with this?
Nimfa-mama [501]

Answer:

Kite x=1, y=7

Step-by-step explanation:

It is a kite.

The two lines on the bottom corners of the kite mean they have the same value.

X=1 so 3x+4

3 *1 +4=7

And: x+6

1+6=7.

X+4=1+4=5.

Y=7 so y-2

7-2=5.

Hope it helped you

A 7-foot tall stop sign creates a shadow that is 2 feet long. At the same time, a utility pole creates a shadow that is 11 feet
sasho [114]
X ft tall: 11 ft shadow
7 ft tall: 2 ft shadow

11÷2= 5.5, 2×5.5=11 so 7×5.5= x
x= 38.5 ft tall

The utility pole is 38.5 ft tall.

What is the value of k in the product of powers below? 10 Superscript negative 3 Baseline times 10 times 10 Superscript k Baseli
poizon [28]

Answer: -1

Step-by-step explanation:

10^-3 x 10 = 10^-2

But you need it to be 1/10^3

So 10^-2 x 10^-1 = -2 + -1

= 10^-3

In order to put it in simplest form, the power needs to be positive.

So = 1/10^3

Meaning the missing power is -1
