Answer and Explanation
1. Males taking geometry
Explanation: Find 19% of 30 to find answer
2. B- Between 40-60 minutes
Explanation: Measure the difference between the intervals
3. B is correct.
Explanation: From the graph the actual heart rate=150=150
but calculated heart rate from best fit line=148=148
Difference between actual and calculated=150-148=2=150−148=2
Substitute the value of the variable into the equation and simplify.
The answer should be D

Answers: 33, 35, 37</h3>
==================================
Explanation:
Consecutive integers are integers like 1,2,3,... or 6,7,8... so they are integers that follow one after another.
Consecutive odd integers are sequences like 3,5,7,... or 21,23,35... meaning they are odd integers following one after another as close as possible.
If x is some integer, then 2x is always even and 2x+1 is always odd
let 2x+1 be that first odd integer
adding on 2 leads to the next odd integer: (2x+1)+2 = 2x+3
adding on another 2 leads to the next one: (2x+3)+2 = 2x+5
The three expressions
2x+1
2x+3
2x+5
represents three consecutive odd integers. They must add to 105
(2x+1)+(2x+3)+(2x+5) = 105
(2x+2x+2x)+(1+3+5) = 105
6x+9 = 105
6x = 105-9
6x = 96
x = 96/6
x = 16
Meaning that
2x+1 = 2(16)+1 = 33 = first odd integer
2x+3 = 2(16)+3 = 35 = second odd integer
2x+5 = 2(16)+5 = 37 = third odd integer
As a check
33+35+37 = 105
which confirms the answer
The ratio between what harry pays to what his dad pays is given as 2:3.
We know that harry's dad paid <span>£</span>52.2, therefore, we can use cross multiplication to find the amount that Harry paid as follows:
harry paid = 52.2 * (2/3) = £34.8
The total cost of the meal would be the addition of what they both paid, this means that:
total cost of meal = 52.2 + 34.8 = £87
