Answer:
<h3>8 and 13</h3>
Step-by-step explanation:
Let the two numbers be x and y
If the two numbers differs by 5, then;
y-x = 5 ...1
x is the smaller
y is the larger
If seven times the smaller plus four times the larger is 108, this is expressed as;
7x + 4y = 108 ... 2
From 1;
y = 5 + x .... 3
Substitute 3 into 2;
From 2;
7x + 4y = 108
7x + 4(5+x) = 108
7x + 20 + 4x = 108
11x + 20 = 108
11x = 108-20
11x = 88
x = 88/11
x = 8
Since y = 5+x
y = 5 + 8
y = 13
hence the numbers are 8 and 13
Answer:
1. Draw out a diagram as a triangle with one side as the 5' rise, the other side as the horizontal run, and the hypotenuse as the ramp.
2. Put the 5 ° in as the angle between the run and the ramp.
3. Let the run = x. Using trigonometry (needed!) the tangent angle (tan) of 5° = opposite/adjacent = 5/x.
4. So x = 5/tan(5°). you will need a scientific calculator to solve.
The probability is 50% or half or 1/2
Absolute value of a number is always the positive number of that number. So it’s just 1 + 10. The answer is 11
