Solve, log.5^4+log4^.5

Answers

Answer 1

Answer: First, let's expand the logarithms.
$log _(5) 4+log_(4)5 = (log4)/(log5)+(log5)/(log4)$
This because $log_(y)x$ is equivalent to $(logx)/(logy)$
From there, you need to use a calculator to find the exact numerical value.
$(log4)/(log5)+(log5)/(log4) = 2.02231716359$

Step-by-step explanation:

The art museum had a total of 224 visitors on Tuesday. Visitors older than 18 paid $12 for admission. Visitors 18 years or younger paid $8 for admission. The museum collected a total of $2,520. How many visitors were 18 or younger?

Answers

Given:
total of 224 visitors
older than 18 paid $12
18 and below paid $8
total collection 2,520

Let l be visitors older than 18 and m be visitors 18 and below.

l + m = 224
12l + 8m = 2,520

l = 224 - m
12(224 - m) + 8m = 2520
2688 - 12m + 8m = 2520
-4m = 2520 - 2688
-4m = -168
m = -168/-4
m = 42 number of visitors 18 and below.

l = 224 - m
l = 224 - 42
l = 182 number of visitors older than 18.

12(182) + 8(42) = 2520
2184 + 336 = 2520
2520 = 2520

"42". I just took the test.

Isabelle earns $22.50 per hour. Last week she worked 50 hours. For any hours over 40hours per week, Isabelle earns 1.5 times her regular hourly wage. What were Isabelle's
total weekly earnings, including overtime pay, for the last week?

Answers

Answer:

$1237.50

Step-by-step explanation:

$22.50 per hr regular

$33.75 per hr overtime

50 hrs total, meaning that she had 10 hrs of overtime.

40 * $22.50 = $900.00

10 * $33.75 = $337.50

$900.00 + $337.50 = $1237.50

Today the coast of a gallon of gas is $2.65. Every week for the next 10 weeks, it will increase by $0.05.a gallon. If you wrote a linear equation to model this situation,what would the slope be?

Answers

We don't need to know how many weeks it kept up
that same rate of increase.

You just told us that it increases by $0.05 a gallon each week.

So the slope of a graph during that period is $0.05 / week.
