Answer:
10.2*6.3=64.26
Step-by-step explanation:
Solve 102*63, then move the decimal point two numbers from the right:
Since 102*63=6426, then moving the decimal point two numbers from the right will mean 10.2*6.3=64.26
Answer:
A solid with surface area 216 square meters and volume 324 cubic meters is dilated by a scale factor of k to obtain a solid with surface area 24 square meters. Find the value of k which leads to an image with the given surface area. Find the volume of the dilated solid.
If 165 cm is 10% taller, then the equation we can use to find the original age is:
x×1.1=165
This means that to solve for x, we just need to divide by 1.1 on both sides of the equation:
x=150
Therefore, Cody was 150 cm tall last year
Answer:
- 13x² - 19x + 23
- -16x +17
Step-by-step explanation:
1 . (4x² - 9x + 16) + (7 + 9x² - 10x)
4x² - 9x + 16 + 7 + 9x² - 10x
13x² - 19x + 23
2 . (-2x + 6) - (14x - 11)
-2x + 6 - 14x + 11
-16x +17
