Answer:

99cm^2

Step-by-step explanation:

When finding an area of a triangle, you multiply base times height and then divide by 2.

In this case,

Height:11

Base: 18

So then apply the formula:

\frac{11*18}{2}

Solve (using a calculator lol)

We get 99

Don't forget units!

So the final answer is 99cm^2

Anna is draining water out of a 50 gallon rain barrel. The graph shows the relationship between time in minutes and the gallons
tatiyna

Answer:

6 < x ≤ 20

Step-by-step explanation:

First, let's use the points (0, 50) and (20, 0) to find the equation of the line.

m = Δy / Δx

m = (0 − 50) / (20 − 0)

m = -2.5

y = -2.5x + 50

Now find the time when y = 35.

35 = -2.5x + 50

-15 = -2.5x

x = 6

So there is less than 35 gallons in the barrel when 6 < x ≤ 20.

There are 12 face cards in a standard deck of 52 cards. How many ways can you arrange a standard deck of 52 cards such that the
evablogger [386]

Answer:

Total number of required ways = 12 × 51!

Step-by-step explanation:

Number of total cards in the deck = 52

Number of face cards in the deck = 12

Now, we need to find the number of ways such that the first card is always a face card

Now, first card is face card so number of cards left to be arranged = 52 - 1 = 51

Number of ways to arrange 51 cards = 51!

Also, Number of face cards = 12

So, Total number of required ways = 12 × 51!

Which function has the same domain as y= 2√x?<br> Oy= √2x<br> O y=2³√x<br> 0₁y = √x-2<br> O y=³√x-2
dybincka [34]

The option first is correct because  y= 2√x and y= √2x have same domain which is x ≥ 0.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

y= 2√x

From the above function the domain should be:

x ≥ 0 (because square root of negative values does not exist)

The function:

y = √(2x)

2x ≥ 0

x ≥ 0

Thus, the option first is correct because  y= 2√x and y= √2x have same domain which is x ≥ 0.
