Answer:
a = 6
b = 2
Step-by-step explanation:
Here, we want to take all values of p up and all values of q down
From the division, 9
goes up and the term above comes down
We have all the following indices rule to use;
(a^x)^y = a^xy
a^x * a^y = a^x + y
a^x / a^y = a^x-y
Let us evaluate all p terms;
p^12/p^4 = p^8
Let us evaluate all q terms
q^16/q^10 * 1/q^2
= q^6/q^2 = q^4
Let us evaluate all number terms
We have;
2^4/-3^2 * 9/4^2
= 16/9 * 9/16 = 1
All
number terms canceled out
Now, let us work with the exponents;
For the p terms;
p^8 = p^a+b
a + b = 8 •••••••••(i)
For the q terms;
q^4 = q^a-b
a-b = 4 ••••••••••(ii)
Add both equations
2a = 12
a = 12/2 = 6
For b;
a-b = 4
6-b = 4
b = 6-4
b = 2

A grocery store offers 10 gas points of gas for every $50 you spend on groceries. For every 10 gas points you earn, you get to take $0.10 off every gallon of gas you buy. Currently, gas is $3.25 per gallon. When Monica fills up her car, she usually puts around 12 gallons of gas in it. How much money must Monica spend at the grocery store to fill up her car for less than $35.00?
Answers
Answer: $2,000
Step-by-step explanation:
Gas is $3.25 per gallon. If Monica needs 12 gallons, cost would be:
= 12 * 3.25
= $39
If she wants to fill up for less than $35, she will have to earn the difference in points:
= 39 - 35
= $4
One can get $0.10 off for every $50 spent. The number of 10 cents in $4 is:
= 4 / 0.1
= 40
Monica would therefore have to spend:
= 50 * 40
= $2,000

Joseph runs 2 1/2 miles on Monday. Each day after that, he runs the same 1 1/3 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?
Answers
Answer:
The answer is C
Number of days= 21/8
Step-by-step explanation:
The inequality to represent the given situation is [tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]. Therefore, option B is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, Joseph runs [tex]2\frac{1}{2}[/tex] miles on Monday. Each day after that, he runs the same [tex]1\frac{1}{3}[/tex] mile route every morning.
Let the number of days be x.
Here, the inequality is
[tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]
Therefore, option B is the correct answer.
