Answer:
log9
Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
logx - logy = log([tex]\frac{x}{y}[/tex])
log[tex]x^{n}[/tex] ⇔ nlogx
Given
2(log18- log3) + [tex]\frac{1}{2}[/tex]log[tex]\frac{1}{16}[/tex]
= 2(log([tex]\frac{18}{3}[/tex] ) ) + log[tex](\frac{1}{16}) ^{\frac{1}{2} }[/tex]
= 2log6 + log[tex]\frac{1}{4}[/tex]
= log6² + log[tex]\frac{1}{4}[/tex]
= log36 + log[tex]\frac{1}{4}[/tex]
= log( 36 × [tex]\frac{1}{4}[/tex] )
= log9

Nine more than the product of a number and 4 is equal to 7.
Answers
Explanation:
It’s saying product of a number and 4 so we would multiply 4 and a variable (I chose n) then it says nine more than that so you would add that to 4n then it equals 7.
Answer:
equation is 9+(4x) = 7
x = -0.5
Step-by-step explanation:
+ 9 to (4x) equals 7
9 + 4x = 7
4x = -2
x = -0.5
to prove:
9+(-0.5*4) = 7
9 + -2 = 7
7 = 7

If the area of a circle is 324 cm, find:
Its circumference in terms of pi
Answers
Answer:
20.3π cm
Step-by-step explanation:
Area of a circle = 324 square cm
πr² = 324
[tex]\frac{22}{7}*r^{2}= 324\\\\ r^{2} = \frac{324*7}{22}\\\\ r^{2}= 103.09\\\\ r =\sqrt{103.09}\\\\[/tex]
r = 10.15 cm
Circumference = 2πr
= 2 * π * 10.15
= 20.3π cm
PLEASE ANSWER
During a flu epidemic the number of sick people triples every week what is the growth rate as a percent ?
Answers
Answer:
2 or 200%
Step-by-step explanation:If the growth rate doubled every week, it would grow by 100% per week. Since the growth rate triples every week, it grows by 200% per week. This is easy to see..... If 1 person is sick at the start.......by the end of the first week, 2 more would be sick. And 2 is 200% of 1. So, 3 people are sick at the end of the first week- triple that of the start. At the end of the second week, 6 more would be sick , and 6 is 200% of 3. So, 9 people total are sick at the end of the second week - triple that of the beginning of the second week

Question 1 1 The area of a rectangle is 1 2/3 square feet. The width of the rectangle is 5/6 feet. What is the length of the rectangle? o foot D 11. feet 0 2 feet O2 feet Question 2 1 p
Answers
Answer:
2ft
Step-by-step explanation:
Given parameters:
Area of the rectangle = [tex]1\frac{2}{3}[/tex]ft²
Width of the rectangle = [tex]\frac{5}{6}[/tex]ft
Unknown:
Length of the rectangle = ?
Solution:
The area of a rectangle is given as:
Area of rectangle = length x breadth
Now insert the parameters and solve for length
[tex]\frac{5}{3}[/tex] = L x [tex]\frac{5}{6}[/tex]
L = [tex]\frac{5}{3}[/tex] x [tex]\frac{6}{5}[/tex] = 2ft

Divide $200 in the ratio 3:2. What is the result?
a. $140 : $60
b. $120 $80
c. $80: $120
d. $300 : $200
Answers
Answer:
b) $120 , $ 80
Step-by-step explanation:
Ratio = 3 :2
Total = 3 + 2 = 5
3/5 of 200 = [tex]\frac{3}{5}*200[/tex]
= 3 * 40
= $ 120
2/5 of 200 = [tex]\frac{2}{5}*200[/tex]
= 2 * 40
= $ 80
You are shopping for a new computer monitor. It is regularly priced at $200 but it is now on sale for 25% off. After the sale discount is applied, you can also use your 20% off coupon. What is the final price?
a. 110
b. 120
c. 130
d. 140
Answers
Answer:
b=120
Step-by-step explanation:
Using proportions, it is found that the final price of the new computer monitor is given by:
b. 120
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
It is regularly priced at $200 but it is now on sale for 25% off, hence 75% of $200 is paid, so:
P1 = 0.75 x 200 = 150.
You can also use your 20% off coupon, hence the final price is of 80% of $150, then:
FP = 0.8 x 150 = $120.
Which means that option B is correct.
