In the figure below, △ A B C ∼△ D E F . BX and EY are altitudes of each triangle. Find the measure of EY to the nearest tenth.

Elena-2011 [213]

Answer:

EY = 5.3 cm

Step-by-step explanation:

∵ Δ ABC similar to ΔDEF

∴ AB/DE = BX/Ey

∵ AB = 12 cm

∵ DE = 8 cm

∵ BX = 8 cm

∴ 12/8 = 8/EY

∴ 12EY = 8 × 8 ⇒ 12AY = 64

∴ EY = 64 ÷ 12 = 5.3333 ≅ 5.3 cm

What is the solution to log Subscript 2 Baseline (9 x) minus log Subscript 2 Baseline 3 = 3

sdas [7]

The value of x is $\frac{8}{3}$

Explanation:

The expression is $\log _{2}(9 x)-\log _{2}(3)=3$

Adding $\log _{2}(3)$ to both sides of the equation, we get,

$\log _{2}(9 x)=3+\log _{2}(3)$

Using log definition, if $\log _{a}(b)=c$ then $b=a^{c}$ , we have,

$9 x=2^{3+\log _{2}(3)}$

Using exponent rule, $a^{b+c}=a^{b} a^{c}$ ,

$9x=2^{\log _{2}(3)} \cdot 2^{3}$

Simplifying, we have,

$9x=3\cdot8\\9x=24$

Dividing both sides by 9, we have,

$x=\frac{24}{9}$

Simplifying,

$x=\frac{8}{3}$

Thus, the value of x is $\frac{8}{3}$

A family has 4 children. find the probability that at least one of the children is a boy.

zubka84 [21]

The probability that one of the children will be a boy is 75%. This is because if the other 3 children were girls, there is no longer a 50% chance there will be a girl. The more girls, the lower the probability.
