Mikayla subtracted 4 from both sides in the beginning when she should've added it to both sides to cancel it out on the right. the correct answer should actually be x=1
Answer:
<h2><em><u>Translation</u></em><em><u> </u></em></h2>
Step-by-step explanation:
A translation moves a shape up, down or from side to side but it does not change its appearance in any other way.
Here also, triangle ABC and triangle A'B'C' are equal only position is changed
Answer:
79 ft
Step-by-step explanation:
Golden rectangle side ratios 1 : (1+sqrt5 )/2
(approx 1: 1.618)
15 + 15 + 2*15*1.618 = <u>~79 ft </u>
BUT perhaps the 15 is the 1.618 side
15/1.618 + 15/1.618 + 15 + 15 ~ 49 feet
Answer:
6) B
7) D
Step-by-step explanation:
6)
The surface area of a cylinder is 2 * pi * r * (r + h)
SA = 2 * 3.14 * 3.6 * (3.6 + 8.5) = 2 * 3.14 * 3.6 * 12.1 = 273.6 cm^2
7)
The volume of a cylinder is pi * r^2 * h
V = 3.14 * (3.6)^2 * 8.5 = 345.9 cm^3
This congruency thing is all about corresponding sides and angles. In quadrilateral BCDE and OPQR, DE and QR are in corresponding positions. You don't even have to draw them out to see that. Just like you can say that angle B and angle O are corresponding, and side BC is corresponding to side OP. Match them up; that's all there is to it!
