1.
558 can be rounded to 600.
44 can be rounded to 40.
600 x 40 = 24,000
2.
9 x 802 = 9 (800 +2) =7200 + 18 = 7218
3.
3699 x 7 = (3700-1) x 7 = 25,900 - 7 = 25,893
4.
34 x 93 = 34 x (100-7) = 3400 - 238 = 3162
5.
678 x 87 = 58,986
Answer:
Because the dashed triangle is smaller than the original it's a reduction. The scale factor is 1/3 because if we look at the altitudes of the triangle, the original is 6 and the dilated is 2 and 2 / 6 = 1 / 3.
Answer:
W=4 l=16
Step-by-step explanation:
Let w = width
Let l = length
Since the length is 4 times the width, l=4w
Perimeter of rectangle = 2l + 2w
= 2(4w)+2w
=10w
The perimeter of the rectangle =40, so
40=10w and w=4
Plug w into the length equation : l=4w=4(4)=16
