Answer:
D
Step-by-step explanation:
7.6/3.8 = 2
The dilation is by scale factor 2.
8/2 = 4
11/2=5.5
Calculate the volume.
Cross section × height
4 × 3.8 × 1/2 × 5.5 = 41.8
The volume of the smaller prism is 41.8 ft³.
Answer:
A = 189 yd²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = DE = 21 , h = the line from F to DE = 18 , then
A = × 21 × 18 = 10.5 × 18 = 189 yd²
Answer:
The x- and y-coordinates have the same sign. Quadrants I and III; Sample answer: In Quadrant I, both coordinates are positive and in Quadrant III, both coordinates are negative. 16. The x- and y-coordinates have opposite signs.
Step-by-step explanation:
They both have on both sides is three angles and an origial point.
<span>(b+3)/7=(b-3)/6
6(b+3) = 7 (b-3)....> cross multiply
6b + 18 = 7b -21 ...>distributive property
6b - 7b = -21 -18 ...>subtract 7b to both sides then simplify
-b = -39 ...> multiply -1 to both sides
b = 39</span>
√(126.x.y⁵)/(32x³)
1st- simplify by (2x) == √(63.y⁵)/(16.x²)
2nd- Or it could be written √(9.7.y⁴.y)/(16x²)
3rd: (3y²/4x) . √7y (3rd Answer)
