Answer:
He needs to buy 120 packages of dod food.
Step-by-step explanation:
b - bird food
h - hamster food
d - dog food
c - cat food
b + h + d + c = 600
b = h (bird food is the <em>same</em> as hamster food)
b = 4 d (bird food is <em>4 times</em> dod food)
c = d/2 (cat food is <em>half</em> dog food)
Total of packages ordered.
b + b + d + c = 600
4d + 4d + d + d/2 = 600
4 d + 4 d + d + d = 600. 2
10 d = 1.200
d= 120 .........the amount of dog food packages.
Need the statements to answer don’t you
<span>To minimize the perimeter you should always have a square.
sqrt(289) = 17
The dimensions should be 17 X 17
To see , try starting at length 1, and gradually increase the length.
The height decreases at a faster rate than the length increases, up until you reach a square.
Or if you want to use algebra, Say the width is 17-x
Then the length is 289/(17-x)
Now, this is bigger than 17+x, as shown here:
289/(17-x) > 17+x
289 > 289 - x^2
which is true.
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17
Again, the dimensions should be a square. 17 X 17.</span>
Given that the angle measure 20 and the side opposite to that angle measures 10 cm, suppose this is the height of the triangle, the hypotenuse
Such that
sin theta=opposite/hypotenuse
opposite=a=10 cm
sin 20=10/h
multiplying both sides by h we get
hsin20=10
hence;
h=10/sin20
h=29.24 cm
h=29.2 cm
Answer: 70.47%
100% - 13% = 87%
19% of 87% = 16.53%
remaining percent
= 87% - 16.53%
=70.47%
