Answer:
30 square feet
Step-by-step explanation:
area= length times width
Answer:
The first one is 5m - 4y.
The second one is 3x - 4y.
Step-by-step explanation:
1) A = π r² = 22/7 x 10² = 314.28 in²
2)A = π r² = 22/7 x 9² = 254.57 mm²
3) radius = 1/2 diameter
r = 1/2 x 3 = 1.5 in
A = π r² = 22/7 x 1.5² = 7.07 in²
4)A = π r² = 22/7 x 14² =616 cm²
5) radius = 1/2 diameter
r = 1/2 x 1.5 = 0.75 ft
A = π r² = 22/7 x 0.75² = 1.76 ft²
#5,
it says that the angle on top is 221, so you subtract that from 360,
360-221= the rest..... 139
Now in that 139, you can see that there is a triangle with a right angle. so you can subtract 90 degrees from 139
139-90= 49
49 is the number you use to solve the rest.
3x + 4x = 7x
so 7x = 49
and then you divide 7 from both sides to isolate x, and you get your answer
K(x)=moles
p(x)=rollls
subsitute k(x) for x in p(x)
p(k(x))=2(x-1)+3=2x-2+3=2x+1
that is
p(x)=2x+1 for
p(x)=rolls
and x is toes
