This problem requires a system of equations, which we can easily come up with. "The length plus the width is 15" is L + W = 15. That is the first of 2 equations. The area is found by multiplying the length by the width, so the next statement, "The area is 44" is L*W=44. Solve that first equation for L to get L=15-W. Now sub that L value into the second equation in place of L to get an equation in terms of W only. (15-W)W=44. We will distribute to get
. Now we will bring the 44 ovr by subtraction and put this into standard form:
. I personally do not like to try to factor polynomials with negative leading coefficients, so let's change all those signs (yes, that's legal):
. If you plug those values into the quadratic formula you will get w values of 11 and 4. It just so happens (and NOT by coincidence) that 11+4 = 15, which fits our "the length of a rectangle plus its width is 15", and 11*4 = 44, which fits our "the area of the rectangle is 44". So the length and width are 11 and 4, respectively.
Answer:
140 degrees
Step-by-step explanation:
im basing it off of the fact that 1 is equal to 35 and so 4 must be 4 times 35 degrees
The time it would take for the print to reach 100 percent completion is 12,101 minutes 9 seconds.
<h3>What is time it would take to reach 100%?</h3>
The mathematical operations that would be used to determine the required value are division and multiplication. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Multiplication is the process of determining the product of two or more numbers. The sign used to denote multiplication is ÷.
Other mathematical operations that are used to solve problems include addition and subtraction.
Time it would take to reach 100% completion = (minutes it takes to print 87% of the words x 100%) / 87%
Time it would take to reach 100% completion = (10,528 x 1) / 0.87 =
10.528 / 0.87
= 12,101. 15
= 12,101+ (0.15 x 60)
= 12,101 minutes 9 seconds

Answer:
8 in²
Step-by-step explanation:
The area of a triangle is always base times half height. Since this triangle has a 90° corner, the vertical 4 inch is also the height.
So area is 4*4/2 = 8
Out of 120 students in exam, 2/3 of them passed. How many students passed?
now,
no of students passed = 2/3×120
= 0.66×120
=80...
therefore <em>8</em><em>0</em><em> </em><em> </em><em>students</em><em> </em><em>were</em><em> </em><em>passed</em><em>.</em><em>.</em><em>.</em><em>.</em>
