Freeman High School's drill team will be attending the national competition and needs to raise $1,600. To raise money for the trip, the girls are selling tickets to a luncheon. Tickets are $8 for students and $10 for adults. The equation 8x+10y=1600, where x represents the number of student tickets sold and y represents the number of adult tickets sold, can be used to represent this situation. The graph of this equation is shown below.

Answer:

  (b) 156 miles

Step-by-step explanation:

In 2 hours, Marian will have driven 2×40 = 80 miles, and Ming will have driven 2×38 = 76 miles. The distance between them is ...

  80 mi + 76 mi = 156 mi

The drivers will be 156 miles apart in 2 hours.

The uniform width of the frame is 16.61 inches.

Since a rectangular canvas picture measures 12 inches by 28 inches, and the canvas is mounted inside a frame of uniform width, increasing the total area covered by both canvas and frame to 612 square inches, to find the uniform width of the frame you must perform the following calculation:

Therefore, the uniform width of the frame is 16.61 inches.

The best definition of the term "reciprocal" is: A fraction that is the multiplicative inverse of the given fraction. The correct option is option B

The reciprocal of a fraction is obtained by swapping the numerator and the denominator of the fraction. It is a number that, when multiplied by another number, results in a product of 1. For example, the multiplicative inverse of 2 is 1/2, because 2 × 1/2 = 1. In general, if a number "a" has a multiplicative inverse "b," then a × b = 1. However, not all numbers have multiplicative inverses.

Reciprocals are also knowns as multiplicative inverse. Multiplicative inverses are essential in various mathematical operations and concepts, including fractions and solving equations involving division.

Answer:

Step-by-step explanation:

The left-side expression will not intersect the right side expression if the slopes are the same and the y-intercepts are chosen appropriately. An example is ...

  |3x +5| = 3x +1

The right-side line stays below the left-side V, so doesn't intersect.

__

You can choose the slopes to be different, also, if you make the intercepts such that the right-side line does not intersect the left-side V. An example of that is ...

  |3x +5| = x -1

Answer:

base = 12; height = 3

Step-by-step explanation:

Area: ( b x h ) / 2

base: 2x

height: (x - 3)

---------------------------------

( ( 2x )*( x - 3 ) )/ 2 = 18

( 2x ^2 - 6x ) = 36

2x ^2 - 6x - 36 = 0

(quadratic formula)

x = 6

x = -3

---------------------------------

taking the positive value : x = 6

---------------------------------

base: 2x = 2(6) = 12

height: x - 3 = 6 - 3 = 3

The constant of proportionality for the amount of flour to sugar in this recipe is 2.

If Kareem uses 3.5 cups of sugar, he will need 7 cups of flour.

Two variables are said to be proportional if an increase in one variable leads to an increase in another variable and vice versa.

Let y represent the cups of flour and x represent the cups of sugar. Hence:

3.5 cups of flour for every 1.75 cups of sugar:

y ∝ x

y = kx

k is the constant of proportionality

3.5  = 1.75k

k = 2

y= 2x

If Kareem uses 3.5 cups of sugar, he will need:

y = 2x = 2(3.5) = 7

The constant of proportionality for the amount of flour to sugar in this recipe is 2.

If Kareem uses 3.5 cups of sugar, he will need 7 cups of flour.
