Answer:
3 miles per hour
Step-by-step explanation:
We know
Jayla ran the first 3 miles of a 5-mile race in an hour.
What was her average rate, in miles per hour, for this first part of the race?
Average rate = Distance / Time
We take
3 ÷ 1 = 3 miles per hour
So, the answer is 3 miles per hour.
B. 16 cm2
C. 8 cm2
D. 6 cm2
E. 4 cm2
The answer is C) 8 cm squared.
That is because 64/8 = 8 cm squared. Hope this helps!!!
Answer:
C. 8 cm2
Step-by-step explanation:
If the big square is 64 cm2, then each side is 8 cm (8cm x 8cm = 64 cm2)
Each of the small squares then has both sides of half the side of the big one, then, each small square has 4cm x 4cm = 16 cm2
Ihen, each small triangle's area (such as ABH) is (b.h)/2, being the base and the height equal to the sides of the small square. Each small triangle is (4cm x 4cm)/2=8cm2
expression below when x = 4
x² + 3x - 6
b. it is not possible to tell weather a is greater than or less than zero
c. a is less than zero
