Answer:

1/8

Step-by-step explanation:

probability for cube(even) = 3/6

probability for color = 1/4

(1/4)*(3/6)=3/24=1/8

Answer: 1/8

Step-by-step explanation:

the probability for getting an even number on the cube is 3/6 or 1/2

the probability of getting red is 1/4

1/2 times 1/4 is 1/8

How do I calculate this? Is there a formula?

Answer:

Height of cables = 23.75 meters

Step-by-step explanation:

We are given that the road is suspended from twin towers whose cables are parabolic in shape.

For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.

Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of $x = 600$ or $x = -600$ , and y at 95.

We know that the equation of a parabola is in the form $y=ax^2$ and here it passes through the point $(600, 95)$ .

$y=ax^2$

$95=a \times 600^2$

$a=\frac{95}{360000}$

$a=\frac{19}{72000}$

So new equation for parabola would be $y=\frac{19x^2}{72000}$ .

Now we have to find the height $(y)$ of the cable when $x= 300$ .

$y=\frac{19 (300)^2}{72000}$

y = 23.75 meters

Question 10 of 21

PSYCHO15rus [73]

ANSWER

A. (4,12)

EXPLANATION

The equations are:

$10x +2y = 64...(1)$

and

$3x - 4y = -36...(2)$

To eliminate a variable we make the coefficients of that variable the same in both equations.

It is easier to eliminate x.

We multiply the first equation by 2 to get:

$20x + 4y = 128...(3)$

We add equations (2) and (3).

$3x + 20x + 4y - 4y = - 36 + 128$

$23x = 92$

Divide both sides by 23

$\frac{23x}{23} = \frac{92}{23}$

$x = 4$

Put x=4 into equation (1).

$10(4)+2y = 64$

$40+2y = 64$

$2y = 64 - 40$

$2y = 24$

$\frac{2y}{2} = \frac{24}{2}$

$y = 12$

The solution is (4,12)

Jacob made a banner for a sporting event in the shape of a parallelogram the area of the banner is 127 1/2 square centimeters th

Firlakuza [10]

For a parallelogram, the area is calculated by the equation,
A = bh
where A is area, b is base, and h is height. From this equation, we can solve for the base of the banner by dividing the area by the height.
base of the banner = 127.5 cm² / 4.25 cm
base of the banner = 30 cm
Thus, the measure of the base of the banner is equal to 30 cm.
