Answer: 100 inches

Step-by-step explanation:

From the question, we are given the information that Nia had a 20 inch by 30 inch enlargement made of a photograph and that she wanted to have it framed.

The number of inches of frame that she would use to enclose the photo will be gotten by calculating the perimeter of the shape and this will be:

= 2(length + width)

= 2(30 + 20)

= 2(50 inches)

= 100 inches

To enclose the photo, 100 inches of frame is needed.

What is an equation of the line that passes through the points (1, 6)<br> and (1, 2)?
victus00 [196]

Answer:y = -5x + 11

Step-by-step explanation:

First, find the slope (m) of the line that passes through these points:

m = (1-6) / (2-1) = -5/1 = -5

Then use the point slope formula to find the equation of the line:

m = (y-y0)/(x-x0)

-5 = (y-1)/(x-2)

-5(x-2) = y-1

y - 1 = -5x+10

y = -5x + 11

A cafe sells drink in 3 sizes: small,medium and a large. The small cup cost $0.89 and holds 9 ounces. The medium cost $1.29 and
KatRina [158]
The large cup is best to buy. This is because it costs 11 cents per ounce for the medium cup and 11 cents for the large cup as well. You get almost double the amount for the same price with the large cup.

Simply<br> tan 45°. sin 30° - cot 45°/sec 60°​
dusya [7]

If we want to write the given four numbers in another form, we can write it like this;

tan45=sin45/cos45=1

sin30=sin(\frac{\pi }{2}-60 )=cos60=\frac{1}{2}

cot45=cos45/sin45=1

sec60=1/cos60=\frac{1}{1/2} =2

Now let's rewrite the given expression and get the result.

(tan45.sin30)-(cot45/sec60)=(1.\frac{1}{2})-(\frac{1}{2} )=0
