Answer:
1/80
Step-by-step explanation:
(ab²)^-3 = (a^-3)(b^-6) = [tex]\frac{1}{5}[/tex]b^6
[tex]\frac{1}{5}[/tex]b^6 = 1 /[5(b³)²] = 1 / (5·4²) = 1/80

The population of the UK is 64 million compared to the world's population of 7 billion (7000 million).
Write this proportion as a percentage, correct to 1 decimal place.
Answer:
0.009%
Step-by-step explanation:
64/7000*100=0.009142857%
The proportion of population in UK to the world population is 64 : 7000 or
0.9 %
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
Let the value of population in UK be = 64 milliom
Let the value of world population be = 7 billion
Now ,
The value of 1 billion = 1000 million
So , the value of 7 billion = 7 x 1000 million
The value of 7 billion = 7000 million
Now , the value of world population is = 7000 million
So , the proportion of population of UK to the world population is given by = value of population in UK : value of world population
And , the equation will be
The proportion of population of UK to the world population is = 64 : 7000
The proportion of population of UK to the world population is = 0.00914
The proportion of population of UK to the world population is = 0.9 %
Hence , The proportion of population in UK to the world population is
64 : 7000 or 0.9 %

Step-by-step explanation:
19. Craig Deloy's bank computes 4.25 percent interest on a daily basis. He had $1,250 in the account
for 20 days. He then makes a deposit of $450 and makes no transactions for 10 days. He then
withdraws $300 and makes no transactions for 8 days.
a. How much interest does he earn in the 38 days total?
Answer:
Interest he earn in the 38 days total = $2458.57
Step-by-step explanation:
As given,
Rate of interest (R)= 4.25% = 0.0425
Principal (P)= $1250
Now,
Simple Interest (S.I) for 20 days = P×R×T
= 1250×0.0425×10
= 531.25
⇒Interest for 20 days = $531.25
Now,
Total amount = P + S.I = $1250 + 531.25 = $ 1781.25
As He then makes a deposit of $450 and makes no transactions for 10 days.
⇒Total amount become = $1781.25 + 450 = $2231.25
Now,
S.I for next 10 days = 2231.25×0.0425×10
= 948.28125
⇒Interest for next 10 days = $ 948.28125
∴
Total amount = $2231.25 + 948.28125 = $ 3179.53125
As He withdraws $300 and makes no transactions for 8 days.
⇒Total amount become = $ 3179.53125 - 300 = $ 2879.53125
Now,
S.I for next 8 days = 2879.53125×0.0425×8
= 979.040625
⇒Interest for next 8 days = $ 979.040625
a.)
Interest he earn in the 38 days total = Interest in 20 days + next 10 days + next 8 days
= $531.25+948.28125+979.040625
= $2458.571875 ≈ $2458.57
∴ we get
Interest he earn in the 38 days total = $2458.57

Answer:
Step-by-step explanation:
Part A: Slope of parallel lines are equal.
4x - 3y - 7 = 0 ⇔ y = [tex]\frac{4}{3}[/tex] x - [tex]\frac{7}{3}[/tex]
m = [tex]\frac{4}{3}[/tex]
y - 3 = [tex]\frac{4}{3}[/tex] ( x + 2 ) ⇔ y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{17}{3}[/tex] ⇔ 4x - 3y + 17 = 0
Part B: Slope of perpendicular lines are opposite reciprocal.
[tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1
[tex]m_{1}[/tex] = [tex]\frac{4}{3}[/tex]
[tex]m_{2}[/tex] = - [tex]\frac{3}{4}[/tex]
y - 3 = - [tex]\frac{3}{4}[/tex] ( x + 2 ) ⇔ y = - [tex]\frac{3}{4}[/tex] x + [tex]\frac{3}{2}[/tex] ⇔ 3x + 4y - 6 = 0
1 A lawnmower that regularly sells for $200 is on sale for $85. Find the % of change that the price was decreased by ??? percent. Round to the nearest whole percent.
Answer:
The price changed by 92.5 %
Step-by-step explanation:
The regular price of lawn mover = 200 dollars
The new selling price = 85 dollars
Change in selling price = 200 -85 dollars = 115 dollars
% change == [tex]\frac{185}{200} * 100 = 92.5[/tex]
The price changed by 92.5 %
4. David hikes 2 1/4 miles in 1/2 hour. At this rate how long will it take him to walk 1 mile? If he walks for 1 hour,
how far will he have gone? yes
Answer: 4.50 miles.
Step-by-step explanation:
David hikes 2 1/4 miles in 1/2 hour. To make it easier, we can turn the fractions into decimals.
David hikes 2.25 miles in 0.5 miles.
The ratio of miles hiked to the hours hiked is 2.25 : 0.5. For every 0.5 hours, David hikes 2.25 miles.
To find how many miles David walks in 1 hour, we should multiply the original ratio by 2. 0.5 x 2 = 1, and we need to find how far David walks in 1 hour.
If David hikes 2.25 miles in half an hour, then he will walk 4.50 miles in 1 hour. So the answer is that David will walk 4.50 miles in 1 hour.
