Answer:
X=-1,y=-2
Step-by-step explanation:
if y =2x
2x=4x+2
so X=-1 and y=-2
Answer:
(1) The sum of the lengths of the edges of the cube is 36.
A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3
Volume = 3*3*3 = 27
(2) The surface area of the cube is 54.
A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)
6s^2 = 54
s = 3
Volume = 3*3*3 = 27
Step-by-step explanation:
All you need to uniquely define a cube is any one measurement - length of a side/edge, area of a surface, volume etc. If you have any one of them, you can uniquely determine the others. So each statement alone is sufficient here.
To show how,
(1) The sum of the lengths of the edges of the cube is 36.
A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3
Volume = 3*3*3 = 27
(2) The surface area of the cube is 54.
A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)
6s^2 = 54
s = 3
Volume = 3*3*3 = 27
Answer:
w=√200 (or 14.14)
y=20
yea pretty simple its just the Pythagorean theorem and the fact that a triangle with equal base angles is isosceles triangle
Answer:
the answer is x=6 or x=-16
Answer:
cup of blueberries
Step-by-step explanation:
Since David starts out with 3 1/2 cups of blueberries and uses 1/4 cup to make a smoothie, we will need to subtract 1/4 from his starting amount of 3 1/2
David now has 3 1/4 cup of blueberries
David then uses half of this new amount of blueberries to make his pancakes. We will need to divide by 2 in order to figure out how much half is
- First we can turn 3 1/4 into an improper fraction to make it easier to work with → 3 1/4 = 13/4
- Now dividing 13/4 by 2 gives us
- David used 13/8 cups of blueberries to make his pancakes
- Turning this back into a mixed number leaves him with 1 5/8 cup of blueberries
