Answer:

43. 171 × $4.50 = $769.50

(171 ÷ 9) × 2 = 38

38 × $7.25 = $275.50

$769.50 + $275.50 = $1,045.00

$1,045.00 × 1.04 = $1,086.80

Answer: $1,086.80 for museum tickets and parking

171 + 38 = 209

209 × $6.00 = $1,254.00

$1,086.80 + $1,254.00 = $2,340.80

Answer: $2,340.80 for the total budget

44. Equation: 2a + 10 = 70

2a + 10 = 70 (subtract 10 from each side)

2a = 60 (divide each side by two)

a = 30

Answer: 30 envelopes

45. Inequality: $2.20x + $2.40 < $9.00

$2.20x + $2.40 < $9.00 (subtract $2.40)

$2.20x < $6.60 (divide by $2.20)

x < 3

Answer: x < 3

3 ÷ 4 = 0.75

Answer: 0.75 inch(es) per minute

The only time Landon's elevation changed was from minutes 4 - 10 and 14 - 18. We know that Landon's elevation changed the fastest between minutes 14 - 18, because this occurred over the shortest period of time.

Any quadrilateral which can be inscribed in a circle, is called a cyclic quadrilateral.

The main theorem about these quadrilaterals is the following:

In any cyclic quadrilateral, the sum of the measures of the opposite angles is 180°.

This means, m(∠S)+m(∠Q) =180°,

thus

(7x-2)+(5x+14)=180

12x+12=180

12x=168

x=168/12=14

Thus the measures of angles Q and S are respectively:

7x-2 = 7*14-2=96 (degrees) and

5x+14=5*14+14=6*14=84 (degrees)

Answer: D

The graph of F(x) shown below resembles the graph of G(x) = x ^ 2 but it has been changed somewhat . Which of the following coul

sukhopar [10]

Answer:

f(x) = 3 $x^{2}$ + 2

Step-by-step explanation:

Given G(x) = $x^{2}$

As we can see, the graph of f(x) is 2 units above the graphof g(x) in vertical (vertical shift)

=> f(x) = a $x^{2}$ + 2

As you can see, the graph of f(x) is stretched vertically by a dilation factor of 3

and there is no reflection, so a= 3

=> the equation of f(x) is: f(x) = 3 $x^{2}$ + 2
