7)Fraction of apple pie after eaten by Jeremy = 1 - (1/3) = 2/3

Fraction of pie eaten by Sara

$= \dfrac{1}{4}*\dfrac{2}{3} \\\\\\= \dfrac{1}{2*3}\\\\=\dfrac{1}{6}$

$Fraction \ of \ allowence \ spent \ on \ magazines = \dfrac{5}{8}*\dfrac{2}{3}=\dfrac{5*1}{4*3}=\dfrac{5}{12}$

Fraction left = $1 -\dfrac{5}{12}=\dfrac{12}{12}-\dfrac{5}{12}=\dfrac{12-5}{12}=\dfrac{7}{12}$

The width of a triangle is six more than twice the height. The area of the triangle is 88in2. Find the height and base of the tr

malfutka [58]

For this case we have that by definition, the area of a triangle is given by:

$A = \frac {b * h} {2}$

Where:

b: It is the base of the triangle

h: It is the height of the triangle

According to the statement data we have:

$b = 6 + 2h$

Substituting we have:

$88 = \frac {(6 + 2h) * h} {2}\\176 = 6h + 2h ^ 2\\2h ^ 2 + 6h-176 = 0$

We divide between 2 on both sides:

$h ^ 2 + 3h-88 = 0$

We factor by looking for two numbers that, when multiplied, are obtained -88 and when added together, +3 is obtained.

These numbers are +11 and -8.

$(h + 11) (h-8) = 0$

We have two roots:

$h = -11\\h = 8$

We choose the positive value.

Thus, the base of the triangle is: $b = 6 + 2 (8) = 22$

Answer:

The base of the triangle is 22 units.
