3 0

Just so you know, you can always use a calculator... or google which I know you have access to, considering you are on this site. Well, actually you could be using the brainly app but that's not the point. What I am trying to say is... you don't have to waste your points on questions like this! That's what Google is for :) Btw... your answer is 193

Ming has a standard 52-card deck. A standard 52-card deck has 4 suits (♠, ♣,♦, and ♥) and an equal number of cards of each suit.

soldier1979 [14.2K]

Answer:

Option D.

Step-by-step explanation:

Total number of cards = 52

Total number of cards of each suit (♠, ♣,♦, and ♥) = 13

The probability of getting a card of heart is

$\text{Probability of getting a card of heart}=\frac{\text{Number of heart cards}}{\text{Total number of cards}}$

$\text{Probability of getting a card of heart}=\frac{13}{52}$

$\text{Probability of getting a card of heart}=\frac{1}{4}$

The probability of getting a card other then heart is

$1-\frac{1}{4}=\frac{3}{4}$

If Ming randomly draw a card from the deck 300 times, putting the card back in the deck after each draw, then the number of cards she will draw something other than a heart is

$300\times \frac{3}{4}=225$

Close to 225 times but probably not exactly 225 times.

Therefore, the correct option is D.

What is the area of the given figure?

kirza4 [7]

$\huge\boxed{192\ \text{in}^2}$

There are three parts to this figure: a rectangle and two triangles that are congruent.

We'll add together the area for each to get the total area.

We'll start by finding the area of the rectangle. We don't know its length, so we need to find the bases of the triangles and add them together.

We know that $a^2+b^2=c^2$ . Substitute and solve for $a$ :

$\begin{aligned}a^2+6^2&=10^2\\a^2+36&=100\\a^2+36-36&=100-36\\a^2&=64\\\sqrt{a^2}&=\sqrt{64}\\a&=8\end{aligned}$

Now, double this to get the total length of the rectangle, which is $16$ inches.

The area of the rectangle is equal to its length times its height:

$16\cdot9=\underline{144}$

Now, we'll find the area of one of the triangles and double it since they're congruent.

The area of a triangle is one-half of its base times its height, which we then double.

$2\left(\frac{1}{2}\cdot b\cdot h\right)$

The $2$ and the $\frac{1}{2}$ cancel each other out.

$b\cdot h$

Substitute and solve:

$8\cdot6=\underline{48}$

Finally, add the rectangle's area to the two triangles' area.

$144+48=\boxed{192}$

Juan's 3 math quizzes this week took him 1/3 hour, 4/6 hour, and 1/5 hour to complete. Which list shows the lengths of time from

Marysya12 [62]

The order from least to greatest would be 1/5, 1/3, then 4/6.

To solve, multiply the fractions so that they all have the same denominator. I multiplied the 1/3 by 10, 1/5 by 6, and 4/6 by 5. After they all have a common denominator, you can easily order them from the numerator.

10(1/3) = 10 / 30
6(1/5) = 6 / 30
5(4/6) = 20 / 30
6/30, 10/30, 20/30

Hope this helps! :)
