Answer:

a) 1 in : 6 in

b) P=32 inches

A =60 inches ^2

c) P= 16 ft

A = 15 ft ^2

Step-by-step explanation:

The drawing is 6 inches tall, while the real flag is 3 ft tall

Change ft to inches

3 ft * 12 inches/1ft = 36 inches

drawing : real life

6 36

Divide each by 6

1 6

The scale is 1 to 6

So for every 1 inch on the drawing, there is 6 inches in real life

b) P= 2(l+w) = 2(10+6) = 2(16) = 32 inches

A = l*w = 10*6 =60 inches ^2

The drawing is 10 inches by 6 inches

Multiply by the scale factor of 6

Real life is 60 inches by 36 inches

Divide by 12 to get back to ft

5ft by 3 ft

P= 2(l+w) = 2(5+3) = 2(8) = 16 ft

A = l*w = 5*3 =15 ft ^2

To increase an amount by 22%, multiply by?

madam [21]

Multiply by .22 then add that answer to what you multiplied. For example, you need to increase 100 by 22%. 100 × .22 = 22. 100 + 22 = 122

The question.

Tanya [424]

The solution to this problem can be found by taking 20% of $62.50:

0.2(62.5) = 12.5

The way the question is worded is confusing, but I think it's asking how much of a discount you would get. You would receive a $12.50 discount.

Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credi

Vikki [24]

The equation of the circle: $(x-a)^2+(y-b)^2=r^2$

where:
(a; b) - coordinates of the center
r - a radius

Use: $(a\pm b)^2=a^2\pm2ab+b^2\ \ \ \ (*)$

We have:

$x^2-4x+y^2+8y=-4\\\\x^2-2x\cdot2+y^2+2y\cdot4=-4\ \ \ |add\ 2^2\ and\ 4^2\ to\ both\ sides\\\\\underbrace{x^2-2x\cdot2+2^2}_{(*)}+\underbrace{y^2+2y\cdot4+4^2}_{(*)}=-4+2^2+4^2\\\\(x-2)^2+(y+4)^2=-4+4+16\\\\(x+2)^2+(y-4)^2=16\\\\(x+2)^2+(y-4)^2=4^2$

Answer:
The center: (-2; 4)
The radius: r = 4

OMG GUYS HELP ASAP!!!! THIS IS MY HW ALSO!

One point: draw the line a bit lower such that it touches the circle. A line from the center of the circle to the line will be perpendicular to it.

Two points: draw the line somewhere through the circle. There will be two intersection points.

Three points: can't be done.
