Find the probability that a randomly chosen point is located within the shaded region. Write your answer as a decimal, and
Andrei [34K]

Answer:

Probability = 0.25

Step-by-step explanation:

Given

The attached shape

Required

Probability of locating within the shaded region

First, calculated the area of the shaded region

A_1 = 0.5 * base * height

Where

base = 8cm\\ height = 6cm --- given

So:

A_1 = 0.5 * 8cm* 6cm

A_1 = 24cm^2

Next, calculated the area of the complete rectangle

A_2 = Length* Width

Where

Width = 12cm\\ Length = 8cm --- given

So:

A_2 = 12cm * 8cm

A_2 = 96cm^2

The required probability is:

Probability = \frac{A_1}{A_2}

Probability = \frac{24cm^2}{96cm^2}

Probability = 0.25

A cyclist rides his bike at a rate of 5 kilometers per hour.what is this rate in
il63 [147K]

Answer:

rate is 8 miles per hour and he travels 40 miles per 5 hours

Step-by-step explanation:

The story problem told that i should assume that 1 mile is 1.6 km

so 5km/hr is equal to 8m/h

i got it by multiplying 5 by 1.6 so i can change from the unit km to mile

so about the miles per 5 hours just multiply the 8 mph by 5 so it is 40

40miles per 5hrs

hope i made it clear

A serving size for pineapple-orange punch is 1/2 cup. Liam needs to make 72 servings of punch. He will use 8 pints of pineapple
Hunter-Best [27]
Since a serving is 1/2 cup and he needs 72 servings you can multiply 72 by 1/2 and find out that he needs to make 36 cups of punch. Two cups is a pint so he needs (36 / 2) 18 pints of juice. He already has the 8 pints of pineapple juice so 18 - 8 leaves 10 pints of orange juice.

Which shows how to find the value of this expression when x=-2 and y=5? <br> (3x^3y^-2)2
Gnoma [55]

Put x = -2 and y = 5 to the expression.

(3x^3y^{-2})^2

\left[3\cdot(-2)^3(5)^{-2}\right]^2=\left[3(-8)\cdot\dfrac{1}{5^2}\right]^2=\left(-24\cdot\dfrac{1}{25}\right)^2=\left(-\dfrac{24}{25}\right)^2\\\\=\dfrac{24^2}{25^2}=\dfrac{576}{625}

explanation

(-2)^3=(-2)(-2)(-2)=-8\\\\a^{-n}=\dfrac{1}{a^n}\to5^{-2}=\dfrac{1}{5^2}=\dfrac{1}{(5)(5)}=\dfrac{1}{25}\\\\a^2\geq0\ \text{for any real number}\to\left(-\dfrac{24}{25}\right)^2=\left(\dfrac{24}{25}\right)^2\\\\\left(\dfrac{a}{b}\right)^2=\dfrac{a^2}{b^2}\to\left(\dfrac{24}{25}\right)^2=\dfrac{24^2}{25^2}=\dfrac{(24)(24)}{(25)(25)}=\dfrac{576}{625}
