198 round to the nearest hundreds is 200
198 round to the nearest tens is 200 too
Area of the base = 1/2 x 3 x ( 2 + 5 ) = 10.5 cm²
Volume =10.5 x 10 = 105 cm³
Answer: 105 cm³
1. 78 = 0.15x
78 / 0.15 = x
520 = x.....so 78 is 15% of 520
2. | 3x - 2 | = 8 | x + 1 | = 1
3x - 2 = 8 -(3x - 2) = 8 x + 1 = 1 -(x + 1) = 1
3x = 8 + 2 -3x + 2 = 8 x = 1 - 1 -x - 1 = 1
3x = 10 -3x = 6 x = 0 -x = 2
x = 10/3 x = -2 x = -2
ur answer is : x = -2
3. 3y - 4x + 5 = 0
3y = 4x - 5
y = 4/3x - 5/3
slope = 4/3
Given :
Two similar triangle.
To Find :
The ratio of the area of triangle abc to the area of triangle edc.
Solution :
ΔABC ~ ΔAPQ (AA criterion for similar triangles)
Since both the triangles are similar, using the theorem for areas of similar triangles we have :
Therefore, ratio of area of triangle is 1.4 .
Answer:
22/63
Step-by-step explanation:
Keep, change, and flip is how you divide fractions. You change divide to multiply and then turn 2 5/8 into an improper fraction. And you will get 21/8. Next, flip that number to the reciprocal, which is 8/21. Multiply 8/21 with 11/12 to get 22/63.
