To solve the problem we must know about the change of base rule for Logarithm.
What is the change of base rule for Logarithm?The change of base rule for Logarithm helps us to change the base of any logarithmic expression to any other logarithmic expression.
[tex]log_ab = \dfrac{log_x b}{log_x a}[/tex]
where x is any base.
The expression can be expressed as [tex]\dfrac{log\ 81}{log\ 12}[/tex].
Given to us
[tex]log_{12}81[/tex]Change of base rule[tex]log_{12}81\\[/tex]
use the change of base rule, [tex]log_ab = \dfrac{log\ b}{log\ a}[/tex],
[tex]log_{12}81=\dfrac{log\ 81}{log\ 12}[/tex]
Hence, the expression can be expressed as [tex]\dfrac{log\ 81}{log\ 12}[/tex].

Amirah is 4 years older than Priya and Shirley is
2 years younger than Priya. If the sum of their ages
is 47, find their respective ages.
Answer:
Priyah = 15
Amirah = 19
Shirley = 13
Step-by-step explanation:
Let A represents Amirah, P Priyah and S, Shirley.
So, we have:
[tex]A = 4 + P[/tex] --- 4 years older
[tex]S = P - 2[/tex] --- 2 years younger
[tex]A + P + S = 47[/tex]
Required
Find their ages
Substitute 4 + P for A and P - 2 for S in [tex]A + P + S = 47[/tex]
[tex]4 + P + P + P - 2 = 47[/tex]
[tex]4 + 3P - 2 = 47[/tex]
Collect Like Terms
[tex]3P = 47 - 4+ 2[/tex]
[tex]3P = 45[/tex]
Divide both sides by 3
[tex]P = \frac{45}{3}[/tex]
[tex]P = 15[/tex]
Substitute 15 for P in [tex]A = 4 + P[/tex] and [tex]S = P - 2[/tex]
[tex]A = 4 + 15[/tex]
[tex]A = 19[/tex]
[tex]S = 15 - 2[/tex]
[tex]S = 13[/tex]
4. Brett is fencing in a circular patio. The radius of the patio is 70 feet. How many linear feet of
fencing does he need to enclose the patio?
Answer:
The number of feet of fencing that he needs will be equal to the perimeter of the circular patio.
We know that the perimeter of a circle of radius R is equal to:
P = 2*pi*R
where pi = 3.14
Then if the radius of the patio is 70ft, the perimeter of the patio will be:
P = 2*3.14*70ft = 439.6 ft
Then he needs 439.6 ft of fencing to enclose the patio.

Mrs. Smith has a total of 25 kids in her class. There are 3 more boys than there are girls. Write a system of equations to model this. Use b to represents the boys and g to represent the girls.
Answer:
b + g = 25
b = g + 3
Step-by-step explanation:
Let b = number of boys.
Let g = number of girls.
"Mrs. Smith has a total of 25 kids in her class."
b + g = 25
"There are 3 more boys than there are girls."
b = g + 3
The system of equations is:
b + g = 25
b = g + 3

When is it appropriate to use the paired t test (involving the mean of the differences)? A. When two independent samples are compared. B. When two dependent samples are compared. C. When four samples are compared at once. D. When any two samples are compared.
Answer:
B. Two dependent samples are compared
Step-by-step explanation:
We use it when we are comparing Two dependent samples. The paired t-test can be likened to the repeated measures ANOVA test. Both of these two test are useful when comparing how a static group does in different test conditions.
But the difference between these two are:
We use the paired t-test if the explanatory variable has two levels.
While the Repeated measures ANOVA is used when the explanatory variable has greater than two levels.
Helen needs 60 g of sugar to make 15 biscuits.
She also needs
three times as much flour as sugar
two times as much butter as sugar
Helen is going to make 60 biscuits.
a) Work out the amount of flour she needs.
Helen has to buy all the butter she needs to make 60 biscuits.
She buys the butter in 250 g packs.
b) (i) What is the exact amount of butter she needs?
g
(ii) How many packs of butter will she have to buy?
Answer:
1 pack of butter, and 360 grams flour.
Step-by-step explanation:
it just mental math, and i kinda forget how i even got the answer, but its 1 because she only needs 240 grams. and also 360 flour.
Answer:
I'll give you the correct answer:
a) You need to times 60 by 3: 60*3. This will get you 180g, which gets your first mark.
Next, you must times 180 by 4: 180*4. This gets you 720g, and there's your final answer + the last marks.
b) (i) 420g
(ii) 2 packs, because there is 240 g in one pack so you times it by two.
