Hayden brought 18 new trading cards. Three-fourths of the new cards are baseball cards. How many baseball cards did Hayden buy

marshall27 [118]

<span>He bought 36 baseball cards. Since 3/4 of the 48 cards are baseball cards, you need to find 75% of 48, which is 36 cards. </span>

The two lines y = x + 9 and y = -x − 9 are:

Bond [772]

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

To tell whether two lines are parallel or perpendicular, look at their slopes.

Parallel lines will have the same slope. This isn't the case since the first line has a slope of 1 and the second has a slope of -1.

Perpendicular line have slopes that are negative inverses of the other. This also isn't the case for these two lines. Although the slopes have opposite signs, the numbers aren't inverses.

The two lines are neither parallel nor perpendicular.

For a circle with a diameter

meriva

Answer:

The measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°

Step-by-step explanation:

Here, the diameter of the circle = 6 m

Diameter = 2 x RADIUS

So, radius = D / 2 = 6 / 2 = 3 m

Also, the length of the arc = ( $\frac{5}{2} \pi$ ) meters

Putting π = 3.14, we get

The length S of the arc = $\frac{5}{2} \times (3.14) = 7.85$

or, S = 7.85 m

Let us assume the arc subtends angle Ф at the center of the circle.

⇒ S = r Ф

or, Ф = $\frac{S}{r} = \frac{7.85}{3} = 2.61$

⇒Ф = 2.61 radians

Now, 1 Radian = 57.2958 Degrees

⇒ 2. 62 Radian = 2.61 x ( 57.2958 Degrees) = 149.542 °

or, Ф = 149.542°

Hence, the measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°
