Answer:

4

krok68 [10]

Answer:

I may be wrong but 8 cups of chocolate

Step-by-step explanation:

First I looked over what I needed to do, 1 cup of cream and 2 cups of chocolate.

The next thing I did was attempt to solve it in 2 different ways, the first one being adding 1 cup of cream and 2 cups of chocolate every time, but that didn't work. The second attempt I just kept 1 cup of cream and added 6 cups of chocolate.

I added 6 because there are already 2 cups of chocolate, so that would add up to 8 cups. We didn't add any cups of cream so its still one. 8+1 is obviously 9.

Sorry if I am wrong

Area of Composite Figures
AlekseyPX

Answer:

1) 147

2) 87m^{2}  

Step-by-step explanation:

1) Area of triangle = × base length × height

= \frac{1}{2} × 14 × 10

= 70 m^{2}

Area of a semicircle = \frac{\pi r^{2} }{2} ( r is the radius)

Radius = half of diameter = \frac{14}{2} = 7m

Area of semicircle = \frac{\pi 7^{2} }{2} = \frac{\pi49 }{2}

= 77m^{2} ( Nearest whole number )

Total area = 77 + 70 = 147m^{2}

2) Divide the shape into 2 rectangles

Area of a rectangle = length × width

Rectangle 1 = 7 × ( 3+3+5 )

= 7 × 11 = 77m^{2}

Rectangle 2 = 2 × 5

= 10m^{2}

Total Area = 77 + 10 = 87m^{2}
