Answer:
42
Step-by-step explanation:
Test worth = 50
To obtain a grade percent = 84%
Score to obtain = x
Using the expression :
84% of test worth = x
84/100 * 50 = x
0.84 * 50 = x
42 = x
Score to obtain = 42
Answer:
Step-by-step explanation:
HL=√((-2-4)²+(8-0)²)=√(36+64)=√100=10=radius
so L lies on the circumference of circle.
or eq. of circle is (x-4)²+(y-0)²=10²
(x-4)²+y²=100
Put x=-2,y=8
(-2-4)²+8²=100
36+64=100
or 100=100
which is true.
Hence L lies on the circle.
Answer:
Mario bought five books.
Step-by-step explanation:
If Mario bought n magazines, then n is the solution of
23.85 = 12.60 + n*2.25
23.85 - 12.60 = n*2.25
11.25 = n*2.25
n = 11.25/2.25
n = 5
Answer:
Step-by-step explanation:A function defines one variable in terms of another. The statement "y is a function of x" (denoted y = y(x)) means that y varies according to whatever value x takes on. A causal relationship is often implied (i.e. "x causes y"), but does not *necessarily* exist.
