Answer: 1/6 or 17%

Step-by-step explanation:

So on a die the only multiples of 3 are 3 and 6 so that leaves us with a 2/6 or 1/3 chance of the die and the coin is always a 50% chance so together multiplied is 1/6 or 17 %

Mercedes is going to have her car fixed. Cairo Prince Auto Tech charges $45 for an estimate plus $24 per additional hour of work
strojnjashka [21]
Cairo's cost is modeled by 45 + 24h
Tarantino's is modeled by 30h

For h = 6:
Cairo = 45 + 24*6 = 189
Tarantino = 180

For h = 7
Cairo = 45 + 24*7 = 213
Tarantino = 210

For h = 10
Cairo = 45 + 24*10 = 285
Tarantino = 300

\boxed{2\ and\ 4\ are\ true.}

Lanas avarage step length is about 0.5 meters. How many steps will she need to finish the race? (5 KILMEMETER RACE)
Alex Ar [27]
The length of the race is 5 kilometers.
5 kilometers equals 5000 meters.

Since Lana's avarege step length is about 0.5 meters, we need to divide 5000 by 0.5

Steps = \frac{5000}{0.5} = 10000

Hence, Lana needs to take about 10000 steps.

Identify the equation of the circle that has its center at (-3, -4) and passes through the origin.
Allushta [10]

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - a center

r - a radius

We have:

The center (-3, -4) → h = -3 and k = -4.

The radius is equal the distance between the center of the circle and the origin.

The formula of a distance between two points:

A(x_A,\ y_A),\ B(X_B,\ y_B)\\\\d_{AB}=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}

Substitute

(-3,\ -4),\ (0,\ 0)\\\\d=\sqrt{(0-(-3))^2+(0-(-4))^2}=\sqrt{9+16}=\sqrt{25}=5

therefore r = 5.

Answer:

(x-(-3))^2+(y-(-4))^2=5^2\\\\(x+3)^2+(y+4)^2=25
