Answer:
Height and base are both 12 in
Step-by-step explanation:
Formula area triangle: area = (height * base) /2
Since for the first triangle height and base are the same we will call is x.
The area for the first triangle is
area = (x^2) /2 = 0.5x^2
The new triangle area is
first triangle - 36 = ((x/2) * x)/2
0,5x^2 - 36 = (0,5x * x)/2
0,5x^2 - 36 = (0,5x^2)/2
0,5x^2 - 36 = 0,25x^2
0,25x^2 = 36
x^2 = 144
X = square root (144) = 12 in
I don't listen to k-pop but your answer is x = 8...Brainliest...
Answer:
The answer for this problem is 14.825
Step-by-step explanation:
There are about three steps for this problem
The first is finding out what is 45% of 3.5 yds. You do this by multiplying 3.5 and .45 and you get 1.575
The second step is finding the second carpets length. All you have to do is add the number we got from multiplication which is 1.575 to 3.5 and you get 5.075. The reason we added those numbers is because the problem says the second carpet is 45% "longer" than the first carpet.
The third and final step is to add up all three values and you get 14.825!
<em>1.) </em><em>510 miles</em>
<em>Take the values you have been given which is 153 miles and 3 gallons of gas </em>
<em>Now divide 153 by 3 to find put the Miles per gallon (MPG)</em>
<em>153/3=51</em>
<em>now take 51 and multiply it by 10</em>
<em>51x10=</em><em>510</em>
<em>2.) </em><em>$16 per yard of plywood</em>
<em>Let's take the values we have been given </em>
<em>3/4 of a yard of plywood and $12 for it</em>
<em>Now let's divide it </em>
12/ 3/4=$16
