Given: Isosceles TriangleDEF. The measure of vertex Angle D is four times the measure of each base angle E and F.

777dan777 [17]

Answer:

D = 120° , E = 30° , F = 30°

Step-by-step explanation:

Let D = 4x

Let E&F = x

4x + x + × = 180°[angles in triangle is 180°]

6x = 180°

x = 180/6

x = 30°

E = 30°

F =30°

D =4(30°)

=120°

A bag contains 42 red marbles, 6 white marbles, and 8 gray marbles. You randomly pick out a marble, record its color, and put it

Elanso [62]

For any single draw,

$\mathbb P(\text{white})=\dfrac6{42+6+8}=\dfrac6{56}$
$\mathbb P(\text{gray})=\dfrac8{42+6+8}=\dfrac8{56}$

Drawing a white marble or a gray marble are disjoint events; only one of them can happen. So

$\mathbb P(\text{white or gray})=\mathbb P(\text{white})+\mathbb P(\text{gray})-\underbrace{\mathbb P(\text{white and gray})}_0$
$\mathbb P(\text{white or gray})=\dfrac6{56}+\dfrac8{56}=\dfrac{14}{56}$

Out of 224 draws, you should expect $\dfrac{14}{56}\times224=56$ of the marbles to be either white or gray.

The price of an item yesterday was $60. Today, the price fell to $42. Find the percentage decrease.

oksian1 [2.3K]

Answer:

-30% or 30% decrease

Step-by-step explanation:

What's percentage decrease?

Percent decrease is the difference between the initial value and new value, indicating a loss of value.
The formula to find percent decrease is $\frac{NV-IV}{IV} * 100$ , where NV = new value and IV = initial value.

How do we solve this problem?

We know that the original value was $60, so that represents IV. Also, now that the price is $42, it represents NV.
Now, we plug in the values!
$\frac{42-60}{60} * 100$
$\frac{-18}{60} * 100$
$-\frac{3}{10} * 100$
$-3 * 10$
$-30$

Therefore, the answer is 30% decrease.
