What she scored on her second test

Mathematics
1 answer:
hjlf3 years ago
3 0
Let's say that Maria had 270 as a total score, which is true.
The problem is asking for an addition problem to help determine the second score Maria might have gotten.

In order to solve this, you need an equation.
Knowing the rules of addition and subtraction, you put 92 and 88 together, and get a sum of 180.

92 + 88
is your addition problem in this question

Now, in order to find the difference, or the second score, you need to subtract.

All you need to do is do a simple equation
↓↓                                                           ↓↓
270 (total of all scores including the second one) - 180 (the sum of the addition equation) = 90

Your answer is 90.

Changing Bases to Evaluate Logarithms In Exercise, use the change-of-base formula and a calculator to evaluate the logarithm.
Ymorist [56]

Answer:

\frac{3}{2}

Step-by-step explanation:

Changing Bases to Evaluate Logarithms

log_{16}(64)

Apply change of base formula'

log_b(a)= \frac{log a}{log b}

log term should be the numerator and denominator is the log base

log_{16}(64)

log_{16}(a)= \frac{log 64}{log 16}

64 is 4^3  and 16 is 4^2

log_{16}(a)= \frac{log 4^3}{log 4^2}

Move the exponent before log

\frac{3log 4}{2log 4}

top and bottom has same log so cancel it out

\frac{3}{2}
