Answer:
4.2 km
Step-by-step explanation:
The altitude of the triangle can be found using the triangle area formula:
A = 1/2bh
22.7 km² = 1/2(10.8 km)h
h = (22.7 km²)/(5.4 km) ≈ 4.2037... km
The missing measurement is about 4.2 km.
Answer:
37.7
Step-by-step explanation:
One decimal point is one digit after the decimal point. Here, we round up because the digit after the one we're looking for is greater than 4
Answer:
Step-by-step explanation:
A
The marble is red. There are 6 red marbles out of ten. So the answer is
6/10 = 0.60
B
Red: 1 3 5
Blue: 1 3
So there are 5 ways that you can draw an odd number. The problem is that they are not evenly distributed.
Red: 1/2 * 3/6 = 1/4 = 0.25
Blue: 1/2 * 2/4 = 0.25
Red + blue = 1/4 + 1/4 = 1/2
You could have gotten 1/2 by taking 5/10 but that won't always work.
C
Answer:
Step-by-step explanation:
Given:
1/2(ln(xx + yy) − ln(zz))
Now,
From the properties of log function,
1) n × ln(x) = ln(xⁿ)
and,
2) ln(A) - ln(B) =
applying the properties in the given equation
we get the above equation as:
( using the property 2 we get (ln(xx + yy) − ln(zz) =
or
⇒ ( using the property 1 i.e n × ln(x) = ln(xⁿ) )
expression as an equivalent expression with a single logarithm is
