Answer:
? = 4.29
Step-by-step explanation:
Remark
Let x be the question mark. You get the proportionality by using the dimensions of the little triangle to the dimensions of the large triangle.
Equation
14/(14+ 4) = 15/(x + 15) Combine like terms on the left
14/18 = 15/(x + 15) Cross multiply
14*(x + 15) = 18 * 15 Simplify the right
14(x + 15) = 270 Divide by 14
x + 15 = 270 / 14
x + 15 = 19.29 Subtract 15 from both sides
x = 19.29 - 15
x = 4.29
Answer:
54:73
Step-by-step explanation:
There is more 54's then any other number
73 is the median
Mean = (19 +27 +25+21+44+22+45+34)/8 = 29.625≈30 years
Answer is 30.
Answer:
Step-by-step explanation:
Hello, please consider the following.
We can read from the graph that the vertex is (1,-4) , it means that the equation is, a being a real number.
And the point (0,-1) is on the graph so we can write.
So the equation is.
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
a. m = Vd
b. 6.012g
Step-by-step explanation:
a. you need to rearrange the equation so that you're solving for m. you can do so by multiplying both sides by V so you end up with
Vd = m or m = Vd (i prefer writing it this was purely cause it looks better)
b. now, you can plug in each value into the new equation so you get
5.01g/cm3 x 1.2 cm3 = m
from here you just multiply as normal
