Answer:

A1(8,0)

B1(12,6)

C1(6,8)

Step-by-step explanation:

If its dilated by a scale factor of 1/2, that means for each x and y-coordinate you divide by 2 to get the new scale factor

Originally A(16,0) so now it would be A1(8,0)

Originally B(24, 12) so now it would be B1(12,6)

Originally C(12, 16) so now it would be C1(6,8)

Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 $\pi$ inches

We need to find area of table top

The formula used to find area is: $Area = \pi r^2$

We need to find radius of tabletop.

The formula used to find circumference is: $Circumference = 2\pi r$

Putting value of circumference we can find radius

$Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12$

So, radius of table top = 12

Now, finding the area:

$Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2$

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Sandy is working with a carpenter to frame a house. They are using 8-foot-long boards, but each board must be cut to be 94.6 inc

taurus [48]

1 ft = 12 inches.....so 8 ft = 12* 8 = 96 inches
96 inches - 94.6 inches = 1.4 inches is cut off of each board

PLEASE HELP ME OKT I DONT UNDERSTAND

Answer:

See below.

Step-by-step explanation:

5a)

In an isosceles triangle, the angles opposite the congruent sides are congruent.

m<A = 40 deg

m<B = 40 deg

m<A + m<B + m<C = 180

40 + 40 + m<C = 180

m<C = 100 deg

5b)

In a right triangle, one angle is a right angle.

m<A = 40 deg

m<B = 90 deg

m<A + m<B + m<C = 180

40 + 90 + m<C = 180

m<C = 50 deg
