Solution:

The Expression containing variables raised to power i.e Radicals means combination of base and Exponent is

\frac{(x y^{4})^{-3}}{(x^{-5} y^{5})^{?}}

As while solving these kind of problems, keep in mind the following radical rules:

1. (a^m)^{n}=a^{mn}\\\\2.(ab)^{m}=a^mb^n\\\\3.(a^{m})^{-n}=a^{-mn}

\frac{(x y^{4})^{-3}}{(x^{-5} y^{5})^{?}}

 = \frac{x^{-3}y^{-12}}{(x^{-5}y^{5})^{?}}

So, the first step is in simplifying the expression is Option  B which is →→x to the power of negative 3 multiplied by y to the power of negative 12, the whole over x to the power of negative 5 multiplied by y to the power of 5.

A dog weighs 64 pounds, he eats 3/4 cup of food twice a day. his food contains 429 kcal/cup and 6.5grams protein per 100 kcal of
NeX [460]

Answer:

the dogs daily energy intake is 643.5 kcal

and, the dogs daily protein intake is 41.8275 grams

Step-by-step explanation:

Given:

Food taken per day = 2 × \frac{\textup{3}}{\textup{4}}  cup = 1.5 cup

Amount of calories in a cup = 429 kcal/cup

Amount of protein = 6.5 grams per 100 kcal of energy

now,

The total amount of calories taken per day

= Number of cups of food × Amount of calories in a cup

= 1.5 × 429

= 643.5 kcal

also,

100 kcal of energy = 6.5 grams protein

thus,

1 kcal of energy = 0.065 grams protein

therefore,

643.5 kcal of energy = 0.065 × 643.5 grams protein

or

643.5 kcal of energy = 41.8275 grams of proteins

Hence,

the dogs daily energy intake is 643.5 kcal

and, the dogs daily protein intake is 41.8275 grams

Answer:

564 tiles

Step-by-step explanation:

there are many ways to solve this soo...

1. convert to centimetres (there are 100 centimetres in 1 metre)

2. the square tiles area = 20*20=400cm

2. find the large area (4.8m x 3.8m or 480cm x 380cm)

480 *380=182400cm

2. find the two smaller areas (1.2m x 1.8m or 120cm x 180cm)

2(120*180)=4.3200cm

3. add to find total area

182400 +43200=225600cm

4. find how many tiles are needed

\frac{225600}{400}= 564 tiles
