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 × 
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:
150kg
Step-by-step explanation:
50 oranges ----- 7.5 kg
1000 ------- x
50 * x = 1000 * 7.5
x = 7500 / 50
= 750/5
=150
Your answer is D. 16x² - 56xy + 49y².
A perfect square trinomial is the result of a squared binomial, like (a + b)². Using this example, the perfect square trinomial would be a² + 2ab + b², as that is what you get when you expand the brackets.
Therefore, to determine which of these is a perfect square trinomial, we have to see if it can be factorised into the form (a + b)².
I did this by first square rooting the 16x² and 49y² to get 4x and 7y as our two terms in the brackets. We automatically know the answer isn't A or B as you cannot have a negative square number.
Now that we know the brackets are (4x + 7y)², we can expand to find out what the middle term is, so:
(4x + 7y)(4x + 7y)
= 16x² + (7y × 4x) + (7y × 4x) + 49y²
= 16x² + 28xy + 28xy + 49y²
= 16x² + 56xy + 49y².
So we know that the middle number is 56xy. Now we assumed that it was (4x + 7y)², but the same 16x² and 49y² can also be formed by (4x - 7y)², and expanding this bracket turns the +56xy into -56xy, forming option D, 16x² - 56xy + 49y².
I hope this helps!
Answer:
300
Step-by-step explanation:
To find how many carrots, determine how many square units by finding the area. You can calculate the area by finding the area of the inside square 4 by 4 and then adding the area of each triangle on the side.
Area of square = 4*4 = 16 square units
Area of 2 triangles = 2(2*2*1/2)= 2(2) = 4 square units
16+4 = 20 square units.
15 carrots come from 1 square units so 15(20) = 300 carrots
