Answer:

V = 17.5

Step-by-step explanation:

$v = u + at \\ v = 10 + 3(2.5) \\ v = 10 + 7.5 \\ v = 17.5$

I hope that is useful for you :)

Can someone solve this

77julia77 [94]

Answer:

A ≈ 269.81 cm²

Step-by-step explanation:

This shape is a hexagon (it has 6 sides) so let's use the formula for the area of a hexagon.

A = $\frac{3\sqrt{3} }{2} s^{2}$

Where s is the length of the sides

Substitute:

A = $\frac{3\sqrt{3} }{2} s^{2}$

A = $\frac{3\sqrt{3} }{2} 10^{2}$

Solve:

A = $\frac{3\sqrt{3} }{2} 10^{2}$

A = $\frac{3\sqrt{3} }{2} 100$

Multiply the numerator:

A = $\frac{3\sqrt{3} }{2} 100$

A ≈ $\frac{5.12 }{2} 100$

(The numerator reflects a rounded number, but the actual calculations are exact)

Divide the fraction:

A ≈ $\frac{5.12 }{2} 100$

A ≈ 2.6(100)

Multiply:

A ≈ 2.6(100)

A ≈ 269.81 cm²

Therefore, the area is approximately 269.82 cubic centimeters.

According to the general equation for conditional probability, if P(AB)= 3/10 and P(B) =2/5, what is ? P(A l B)?

Alexus [3.1K]

The formula for conditional probablity states that

$P(A | B) = \cfrac{P(A \cap B)}{P(B)}$

Since we know both numerator and denominator, we only need to plug in the values:

$P(A | B) = \cfrac{P(A \cap B)}{P(B)} = \cfrac{\frac{3}{10}}{\frac{2}{5}} = \cfrac{3}{10}\cdot\cfrac{5}{2} = \cfrac{3}{4}$
