Answer:

N= 32/7 OR 4.5714

Step-by-step explanation:

aight so, cross multiply.

N/4=8/7, when you cross multiply you get

7N=32.

transpose so that we separate the N from 7, and you get

N=32/7

which cannot be further simplified, or your answer can be a decimal

4.5714 (4 d.p.)

Answer:

n = 32/7

Step-by-step explanation:

n/4 = 8/7

Using cross products to solve

n*7 = 4*8

7n = 32

Divide each side by 7

7n/7 = 32/7

n = 32/7

Animal shelter house ratio catch a dog that is 9:7. If the shelter only as his dogs and cats what is the ratio of dogs total ani
Molodets [167]

Answer:

The ratio of dogs to animals  \frac{9}{16}.

Step-by-step explanation:

If the shelter captures 9 dogs they also catch 7 cats.

So,

the total number of Animals = Total number of Dogs + Total number of Cats

                                                = 9+7

                                                 =16

Therefore,

The ratio of dogs to animals    = Number of Dogs / Total number of animals

                                                   = \frac{9}{16}

The area of a rectangle is 25/42 and its width is 5/6. What is the length? ASAP
Serhud [2]

Answer:

<h2>length =  \frac{25}{28}</h2>

Step-by-step explanation:

Let the length of the rectangle be l

Area of a rectangle = length × width

From the question

Area = 25/42

width = 5/6

Substitute the values into the above formula and solve for the length

That's

<h3>length =  \frac{area}{width}</h3>

So we have

<h3>length =  \frac{25}{42}  \div  \frac{4}{6}  \\  =  \frac{25}{42}  \times  \frac{6}{4}  \\  =  \frac{25}{7}  \times  \frac{1}{4}</h3>

We have the final answer as

<h3>\frac{25}{28}</h3>

Hope this helps you

Un pájaro vuela en línea recta desde la Copa de un árbol a la de otro árbol que está 2 metros más abajo, formando un ángulo de v
LuckyWell [14K]

The bird flew 5.45m far from the tree.

Step-by-step explanation:

Given,

Sin70° = 0.94

Cos70° = 0.34

Angle of flight = 70°

Refer the diagram attached for better understanding.

Cos70° = (adjacent side) / (hypotenuse)

0.34 = 2/ hyp

hyp = 2/(0.34)

hyp = 5.8 m

We have to find the opposite side of the angle of flight for the distance the bird flew.

Sin70° = (opposite side) /(hypotenuse)

0.94 = (opposite side) / 5.8

Opposite side= 0.94 x 5.8

= 5.45m

The bird flew 5.45m away from the tree to another tree.
