For this one, an easy way to solve it is to break it down into parts. First lets convert 5 feet to inches.

Multiply the number of feet by how many inches are in one foot.

5 times 12= 60 in

Now just add the like terms

60 in + 2 in= 62 inches.

Now we see that Sarah is 62 inches tall, now we can convert to centimeters the same way.

62 times 2.54= 157.48

So that makes C your answer, Sarah is 157.48 cm tall.

10. On one night, a group of 9 rats carried away 45 kg of food. What is the reduced ratio of rats to food weight

GenaCL600 [577]

Answer:

Number of rats : Food weight = 1 : 5

Step-by-step explanation:

Number of rats in the group = 9

Weight of food carried away by them = 45 kg

Ratio of the number of rats and food weight = $\frac{\text{Number of rats}}{\text{Weight of food carried by the rats}}$

= $\frac{9}{45}$

= $\frac{1\times 9}{5\times 9}$

= $\frac{1}{5}$

Therefore, Number of rats : Food weight = 1 : 5

A rectangular area adjacent to a river is fenced in; no fence is needed on the river side. The enclosed area is 1500 square fee

ZanzabumX [31]

Answer:

a) C(x) = 15000/x + 6x +80

b) Domain of C(x) { R x>0 }

Step-by-step explanation:

We have:

Enclosed area = 1500 ft² = x*y from which y = 1500 / x (a) where x is perpendicular to the river

Cost = cost of sides of fenced area perpendicular to the river + cost of side parallel to river + cost of 4 post then

Cost = 10*y + 2*3*x + 4*20 and accoding to (a) y = 1500/x

Then

C(x) = 10* ( 1500/x ) + 6*x + 80

C(x) = 15000/x + 6x +80

Domain of C(x) { R x>0 }
