This is the composit score, which combines all four section:English, reading, math, and science. So if you earn a composit score of 21,you're right in the middle of the pact. Generally, a score of 24 or higher is good
Step-by-step explanation:
So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.
I hope I helped!
Answer:
C = 18.1°
Step-by-step explanation:
A = 142 m²
a = 24 cm, b = 38 cm
Use the formula A = a*b*sinC/2
142 = 24 * 38 * sinC/2 = 456*sinC
sinC = 0.3114
C = 18.1°
