Step-by-step explanation:
again, 2 unknowns.
x = number of 2- points baskets
y = number of 3- points baskets
we know they hit the basket 37 times in a so far unknown mixture of 2-point and 3- point throws.
x + y = 37
which gives us e.g.
x = 37 - y
and we know that with this unknown mixture they scored 80 points.
so,
2x + 3y = 80
as every successful 2-points throw scores 2 points, and every successful 3-points throw scores 3 points.
so, again our 2 equations :
x = 37 - y
2x + 3y = 80
remember, we prepared the first equation so that it gives us already an identity expressing one variable by the other. and that we use in the second equation :
2×(37 - y) + 3y = 80
74 - 2y + 3y = 80
74 + y = 80
y = 6
and from
x = 37 - y
we get
x = 37 - 6 = 31
so, they had 31 2-points throws and 6 3-points throws.
Permutation so 5!/(5-3)!=5!/2!= 5 x 3 x 4= 60 ways.
The is answer E, you have to search for -3 in the x line than search for -2 in the y line
Answer:
<h3>The answer is 68,486.58 g</h3>
Step-by-step explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of granite monument =
25,365.4 cm³
density = 2.7 g/cm³
The mass of the granite monument is
mass = 25,365.4 × 2.7
We have the final answer as
<h3>68,486.58 g</h3>
Hope this helps you
