Step-by-step explanation:
Mass (m) = 11 g
volume (v) = 13 ml
density (d) = ?
We know density is defined as mass per unit volume so
d = m / v
= 11 / 13
= 0.85 g/ml
Density (d) = 0.85 g/ml
Answer:
60.59
Step-by-step explanation:
73%=0.73
0.73*83=60.59
Answer:
ABCD is not a parallelogram
Step-by-step explanation:
Use the distance formula to determine whether ABCD below is a parallelogram. A(-3,2) B(-3,3) C (5,-3) D (-1.-5)
We have to find the length of the sides of the parallelogram using the formula below
= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)
For side AB
A(-3,2) B(-3,3)
= √(-3 -(-3))² + (3 -2)²
= √0² + 1²
= √1
= 1 unit
For side BC
B(-3,3) C (5,-3)
= √(5 -(-3))² + (-3 -3)²
= √8² + -6²
= √64 + 36
= √100
= 10 units
For side CD
C (5,-3) D (-1.-5)
= √(-1 - 5)² + (-5 - (-3))²
= √-6² + -2²
= √36 + 4
= √40 units
For sides AD
A(-3,2) D (-1.-5)
= √(-1 - (-3))² + (-5 -2)²
= √(2² + -7²)
= √(4 + 49)
= √53 units
A parallelogram is a quadrilateral with it's opposite sides equal
From the above calculation
Side AB ≠ CD
BC ≠ AD
Therefore, ABCD is not a parallelogram
Sample Response: The base area , radius, and diameter can be
determined when given the volume and height of a cone. Substitute the
values for the corresponding variables into the formula, and then solve
by simplifying and undoing operations to isolate the variable. To find
the diameter, double the radius.
Answer:
0.6
Step-by-step explanation:
We know that there are 5 counters in total. 3 white and 2 black.
So we know that 3 out of 5 are white and 2 out of 5 are black.
Therefore the chance to get white is 3/5. And for black: 2/5.
We can turn these into decimals, 3/5 = 0.6 (You can make it 6/10 to make it easier.)
And 2/5 = 0.4 (You can make it 4/10 to make it easier.)
Answering the question, you should put your cross/marker on 0.6
