The kilogrammes of calcium found in 173 pounds of calcium is = 78.5 kg. That is option A.
First convert the 173 pounds of calcium to gramma
1 lb(pounds) = 454 g;
Therefore 173 pounds = 173 ×454
= 78,542g
But, 1000 g = 1kg
Therefore, 78542g = 78542 ÷1000
= 78.542
=78.5kg.
Therefore, the kilogrammes of calcium found in 173 pounds of calcium is = 78.5kg.

write the equation of a line in point slope form that passes through the point (3,6) and has a slope of -2/3
Select the correct answer. Which equation represents the vertical line passing through (1,-9)? A x=-9 B. X= 1 C. y=-9 D y=1 Reset
Answer:
x = 1
Step-by-step explanation:
the vertical line is passing through only the x-axis and not the y axis. So the graph is a x = ? All you e have to to is to look for the x coordinate of the point the vertical line is passing through which is 1 and so the answer is x = 1.
Please mark brainliest. Thanks!!!!
x=1 represents the vertical line passing through (1,-9) .
What is vertical line ?A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane.
In a vertical line x-coordinate remain constant, only y-coordinate changes.
The vertical lines are parallel to the y-axis and are perpendicular to the horizontal lines. On a vertical line, all the points on the line have the same x-coordinate.
Here x=1 is the only vertical line which passes through (1,-9) So option B is correct.

Ended amount = 12.20
Amount for guitar wash = 5.80
Find:
Weekly allowance (W)
Computation:
W + 5.80 - W/2 = 12.20
W + 5.80 - 0.5W = 12.20
0.5 W = 6.4
Weekly allowance (W) = 12.80

What is the value of a?
Answer:
a = 43°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
a + 8 + 2a + 43 = 180
3a + 51 = 180 ( subtract 51 from both sides )
3a = 129 ( divide both sides by 3 )
a = 43

If you roll a number cube 60 times and use the results to calculate the experimental probability of rolling a 1, the experimental probability of rolling a 1 will _____ be less than the theoretical probability of rolling a 1.
Answer:
sometimes
Step-by-step explanation:
Theoretical probability is fixed/remains the same because it is based on theory which is calculated, while the experimental probability is based on data that is gained from actually doing it. According to the law of large numbers, the average experimental probability always approaches the theoretical probability.
− 3/4 is a rational number, but not an integer. Explain why below.
− 3/4 is not an integer but a a rational number.
Why is this correct?A rational number is simply a number that can be written as a fraction with both the numerator and denominator being integers (where the denominator's not zero). For instance lets consider 3/4 as an example. It can be expressed as the fraction 3/4, where 3 and 4 are both integers.
On the hand an integer is a number that is not, in the form of a fraction. In the case of 3/4 it cannot be classified as an integer since it represents a fraction, than a whole number.
