Answer:
3.11
Step-by-step explanation:
f(4)=f(4-1)+2
=f(3)+2
=f(3-1)+2+2
=f(2)+4
=f(2-1)+2+4
=f(1)+6
=5+6 (f(1)=5)
=11
Answer:
A or the 1st one
Step-by-step explanation:
Angelo is making 9 dollars per hour but, loses 2 dollars due to the bus fee. So in math form that would be:
9x - 2
And the second part is Tom makes 8 dollars per hour but doesn't have to pay for bus fee. In math form that would be;
8x
So put that together that would be
9x - 2 = 8x
Answer: 22.5 yards
Step-by-step explanation:
There are a total of 20 parts yarn. This means that 3/20 of the carpet is silver. So in order to compare this to the 150 meters of total yarn, you would set up this equation:
3/20 = x/150
Next, you cross multiply:
3*150 = 20*x or simplified would be 450 = 20x
Next, you divide both sides by 20 to get x by itself.
450/20 = 22.5, so x is equal to 22.5
This means you have 22.5 yards of silver in the carpet.
The surface area<span> of any </span>prism<span> is the total </span>area<span> of all its sides and faces. A </span>triangular prism<span> has three rectangular sides and two </span>triangular<span> faces. </span>To find<span> the </span>area<span> of the rectangular sides, use the </span>formula A = lw, where A = area, l = length, and h = height.
The formula <span>A=<span>1/2 </span>bh</span><span> </span>

Step-by-step explanation:
To convert the numbers to percentages, divide each number by the table total (80) and multiply by 100%. That is equivalent to multiplying each number by 1.25%. For example, 18·1.25% = 22.5% (middle table number).
