Answer:
110 chocolate cupcakes
88 vanilla cupcakes
Step-by-step explanation:
5chocolate to 4 vanilla
5x+ 4x = 9x
9x=198,
x = 22
22 * 5=110 chocolate cupcakes
22 * 4=88 vanilla cupcakes
CHECK: 88 + 110 = 198
Answer:
(- 1, 5.5 )
Step-by-step explanation:
Given (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 0.5(x₁ + x₂), 0.5(y₁ + y₂ ) ]
Here (x₁, y₁ ) = (- 4, 6) and (x₂, y₂ ) = (2, 5 ), thus
midpoint = [ 0.5(- 4 + 2), 0.5(6 + 5) ] = [ 0.5(- 2), 0.5(11) ] = (- 1, 5.5 )
Answer:
56.549 cm (choice 1)
Step-by-step explanation:
If the area of the square if 36 cm, then each side is 6 cm.
That means the diameter for each semi circle is also 6 cm.
Formula for a semi circle is 1/2(πr²)
We need the radius, which is half the diameter. So the radius is 6÷2= 3
Now plug in to the formula.
A= 1/2(π3²)
A= 14.137 (nearest hundredths)
Now multiply that by 4, because there are 4 semi circles
4(14.137)= 56.549 cm (nearest hundredths)
