Answer:
5
Step-by-step explanation:
f(4) falls into the category x > -1 because 4 > -1. Therefore, we use the function f(x) = 2x - 3. f(4) will then equal 2(4) - 3 = 5.
Answer:
$17.25
Step-by-step explanation:
Jeffrey earned $65 doing yard work.
He bought a pair of jeans costs = $31.25
and a sweatshirt costs = $16.50
Total amount he spent = 31.25 + 16.50 = $47.75
Now he left with money from his shopping = $65.00 - $47.75
= $17.25
Jeffrey set aside $17.25 for the gift.
Will solve this problem using something called, "proportions."
Where one thing is proportional to another thing.
While this isn't always the case, most of the time the two similar measurements they gave you are the measurements you'll be using as your proportion. This is true in this particular case.
50/17 = x/10
Cross multiply!
17x = 500
Solve for x!
x = 500/17 = 29.41
Rounded off the tree is:
30 ft tall!(Or, 29 ft tall depending on how you want to round it)
3 3/4 divide 2 1/12 = 1.8
The length of longer base is 41 feet
<em><u>Solution:</u></em>
<em><u>The area of trapezoid is given as:</u></em>
Where , "a" and "b" is the length of base and "h" is the height
The length of one base of a trapezoid is 19 less than five times the length of the other base
a = 19 less than fives times b
a = 5b - 19
Height of 18 feet and an area of 477 ft squared
h = 18 feet
area = 477 square feet
<em><u>Substitute the values in above formula</u></em>
Therefore,
a = 5b - 19 = 5(12) - 19 = 41
Thus length of longer base is 41 feet
