Answer:
45
Step-by-step explanation:
Simply start by listing out the numbers from smallest to largest.
We start out with the smallest number following this information being the number 10. The next are 21 and 20. The next are 32, 31, and 30. We can start to see a pattern. If the ten's digit is n, then there are n numbers within that ten-group that have a greater 10's digit than unit's digit. The largest ten-group (90 to 98) has 9 integers following the rules established. Thus, the number of 2-digit integers that have ten's digits greater than units digit is 1+2+3+...+9=45
Answer:
A $2000
Step-by-step explanation:
Let x be the least amount of money the club has to make to get $600 then...
30%x=600
We can convert 30% to a fraction. Any percentage is that number percent over hundred:
Simplify the fraction by dividing it by 10/10. Notice we can only do this since 10/10 is equivalent to 1, so in a sense we are dividing the fraction by 1:
Multiply 10 to both sides
Divide both sides by 3
The club would have to make at least $2000

Answer:
<em>(-3, 3/2)</em>
Step-by-step explanation:
Given the inequality function y-2x<-3, to get the solution, we will need to find the x and y-intercept of the inequality function
y-intercept occurs at x = 0
Substitute x = 0 into the expression
y - 2(0) < -3
y < -3
Find the x-intercept by substituting y = 0 into the expression
0 - 2x < -3
-2x < -3
x > 3/2
<em>Hence the ordered pair is (x, y) = (-3, 3/2)</em>
