Answer:
40 weeks
Step-by-step explanation:
You can use the fact that there are 52 weeks in a year. If she attends school for 3/4 the year, find out what 3/4 of 52 is, and then add 1:
52/1 * 3/4 = 156/4 = 39 This is 3/4 year
39 + 1 = 40

Step-by-step explanation:
Answer:
the areas of these triangles are 83.2cm² and 46.8cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:
4²:3²
16:9
2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:
130(16/16+9)
130(0.64)
=83.2cm²
3. The area of the smaller triangle is:
130(9/16+9)
130(0.36)
46.8cm²
Answer: 22
Step-by-step explanation:
The area of the picture =l×b = 20×16=320
The length of the frame is 16
If the width is x ( and it's uniform)
672- 320= 352
Area of the frame = 16× x=352
x=352/16
x = 22
