Answer:
10cm, 16 cm, 18 cm,
Step-by-step explanation:
The lengths of the sides of a triangle are in the extended ratio 5: 8.9. The perimeter of the triangle is 44 cm.
Sum of proportion = 5 + 8 + 9
= 22
Length of side a
5/22 × 44 = 10 cm
Length of side b
8/22 × 44 = 16 cm
Length of side a
9/22 × 44 = 18 cm
The lengths of the sides of the triangle in cm are 10cm, 16 cm, 18 cm,
Answer:
24m²
Step-by-step explanation:
To find the area of a rectangle, we use the formula A = l * w or Area = length * width.
We know that our length is 2 meters and our width is 12 meters so we can plug these values into the formula to get our answer.
A = 2 * 12 = 24
Remember that area is measured in "square" units and must be raised to the 2nd power.
A = 24m²
Answer:
26.8
Step-by-step explanation:
Because 33.5 was the average of how many students were in a classroom (if there were 4 classrooms), then 33.5 is can somewhat be the average of how many students were in one classroom; 1/4 of the classrooms can hold an average of 33.5.
Total students that were divided into 4 classrooms :
33.5 × 4 = 134
So if there is 134 students that will be grouped into 5 different classrooms, divide 134 by 5 to find the average amount of students that will be grouped.
134 ÷ 5 = 26.8
So, the average amount of students that will be grouped if they were divided into 5 classrooms would be 26.8 .
Hope this helped !
Answer:
88 square inches
Step-by-step explanation:
if the entire square was shaded it would be 14 x 12 (as best as i can see)
the "cut out" or white part of the square is 8 x 10
Entire squre - cutout white part
14 x 12 - 8 x 10
168 - 80
88 sq in
