1 answer:
Marysya12 [62]3 years ago

Answer:

$9.98

Step-by-step explanation:

Valeria bought 2 six-packs of soda for $1.45 each, three bags of chips for $2.49 each and a half-gallon of ice cream for $4.60.

So, the bill amount of Valeria will be $(2 × 1.45 + 3 × 2.49 + 4.60) = $14.97.

Now, Valeria had a coupon for one-third off her total bill at the store.

So, Valeria's bill with the discount will be (1 - \frac{1}{3} ) \times 14.97 = 9.98 Dollars. (Answer)

In the rectangle below, E1=2x -2, FH=3x+6, and m 4IHG =35°.Find Gl and m LIEH
Tpy6a [65]

Recall that the diagonals of a rectangle bisect each other and are congruent, therefore:

\begin{gathered} FH=2EI, \\ GI=EI. \end{gathered}

Substituting the given expression for each segment in the first equation, we get:

3x+6=2(2x-2).

Solving the above equation for x, we get:

\begin{gathered} 3x+6=4x-4, \\ 3x+6+4=4x, \\ 3x+10=4x, \\ 4x-3x=10, \\ x=10. \end{gathered}

Substituting x=10 in the equation for segment EI, we get:

EI=2*10-2=20-2=18.

Therefore:

GI=18.

Now, to determine the measure of angle IEH, we notice that:

\Delta HFG\cong\Delta GEH,

therefore,

\measuredangle GHF\cong\measuredangle HGE.

Using the facts that the triangles are right triangles and that the interior angles of a triangle add up to 180° we get:

m\measuredangle IEH=90^{\circ}-35^{\circ}=55^{\circ}.

<h2>Answer: </h2>\begin{gathered} m\operatorname{\measuredangle}IEH=55^{\operatorname{\circ}}, \\ GI=18. \\  \end{gathered}
