A bag contains 42 cups of dog food. Your dog eats 2 1/3cups of dog food each day. Is there enough food to last 3 weeks?

Answers

Answer:

it will last 18 days

Step-by-step explanation:

divide 42 by 2 1/3

2 1/3 = 7/3

42 / 7/3 =

42 * 3/7 =

126/7 = 18

if this isn't enough then here

The number of days it will take the dog to consume the 42 cup of food will be 18 days.

Total cups of dog food = 42 cups

Amount of cups consumed per day =

To obtain the number of days it will take to consume the entire food :

Divide the total amount of food by the amount consumed per day

Hence,

(42 ÷ (7/3))

Take the reciprocal of 7/3 and change the operation sign to multiplication

42 × 3/7 = (42 × 3) / 7 = 126 / 7 = 18 days

Therefore, it will take the dog 18 days to finish up the 42 cups of food.

How far away from the tree is the girl ? A. 30 feet
B. 70 feet
C. 20 feet
D. 50 feet

Answers

Answer:

The correct option is C. 50 feet.

Therefore the girl is 50 feet away from the tree.

Step-by-step explanation:

Consider a Right angle Triangle

Elevation to the tree is ' θ '

Adjacent Side to θ = distance from the tree to girl = distance

Opposite Side to θ = height of the tree = height

$\tan \theta =(20)/(50)$

To Find:

distance from the tree to girl = distance

Solution:

In Right angle Triangle Tangent Identity

$\tan \theta = \frac{\textrm{side opposite to angle theta}}{\textrm{side adjacent to angle theta}}$

Substituting we get

$\tan \theta = \frac{\textrm{height of the tree}}{\textrm{distance from the tree to girl}}$

$\tan \theta = (height)/(distance)$

$\tan \theta =(20)/(50)$ ........Given

Comparing the given equation with the above we get

$distance =50\ feet$

Therefore the girl is 50 feet away from the tree.
