Part a : you could draw a line from each corner to the middle
This would give you 7 triangles in total
Part b : area of one triangle : 4.5*7.8 = 35.1 / 2 = 17.55in <-- area of 1 triangle
Part c : so if there are 7 triangles and the area of 1 triangle is 17.55, you would do:
7 * 17.55 = 122.85
Answer: of each shape? 3 & 4?
Step-by-step explanation:
Area of parallelogram<span>=</span><span>base x </span><span>height
Given :
Base = 12 in.
Height = 3 in.
Hence,
Area = 12 x 3
= 36 in. square</span>
3+5=8
8/20 =.4
.4 goes to 40% bc you move the decimal over twice
Answer:
There are 178 more boys in Barlow school as compared to Willow school.
Step-by-step explanation:
We are given the following in the question:
Barlow school:
Total number of students = 873
Number of boys =
![=\dfrac{4}{9}\times 873 = 388](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B4%7D%7B9%7D%5Ctimes%20873%20%3D%20388)
Willow school:
Total number of students = 630
Number of girls =
![=\dfrac{2}{3}\times 630 = 420](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B2%7D%7B3%7D%5Ctimes%20630%20%3D%20420)
Number of boys =
Total number of students - total number of girls
![=630-420 = 210](https://tex.z-dn.net/?f=%3D630-420%20%3D%20210)
Thus, Barlow school has greater number of boys than Willow school.
Difference between the number of boys =
![=388-210\\=178](https://tex.z-dn.net/?f=%3D388-210%5C%5C%3D178)
Thus, there are 178 more boys in Barlow school as compared to Willow school.
