Answer:
A) 3.44 ft²
Step-by-step explanation:
before cutouts, the area was 4 x 4 = 16 ft²
the circles have a diameter of 2 ft each, and a radius of 1 ft
each circle has an area pf (3.14)(1²) = 3.14 ft²
3.14 x 4 = 12.56 ft²
16 - 12.56 = 3.44 ft² left
Answer:
6 litres
Step-by-step explanation:
9:3=3
2×3=6
therefore the answer is 6.
That is (f(-2)-f(1))/(-2-1)
ust find the slope between the points (-2,f(-2)) and (1,f(1))
f(-2)=(-2)^2+5(-2)-12=4-10-12=-18
f(1)=1^2+5(1)-12=1+5-12=-6
slope between them is (-18-(-6))/(-2-1)=(-18+6)/(-3)=-12/-3=12/3=4
average rate of change is 4
Answer:
5/3 teaspoons (if you don't want an improper fraction, it's 1 2/3 teaspoons)
Step-by-step explanation:
If she uses 1 tsp for 3 cups, then the amount needed for one cup is 1/3 tsp.
Since the mother is using 5 cups, just multiply 1/3 by 5, which equals 5/3.
