Answer: 3.4

Step-by-step explanation:

\sqrt{9}=3

\sqrt{16}=4

16-9=7

12-9=3

3/7 ==> 0.4

\sqrt{12}=

\sqrt{9+3}=

\sqrt{9}+0.4=

3+0.4=3.4

Milli plans to rent a room for her birthday party for $40. The catering charge is $12 per person but there is no charge for mill
zalisa [80]
Hello there! So, the room is $40 to rent, and it costs $12 per person. To solve this, we can write and solve an equation. Set it up like this:

40 + 12g = 100

This is because Milli has $100 to spend. $40 is the fixed cost and the $12 goes up based in the number of guests. Let’s start off by subtracting 40 from both sides. 40 - 40 cancels out. 100 - 40 is 60. That leaves us with 12g = 60. Now, divide each side by 12 to isolate the g. 12g/12 cancels our. 60/12 is 5. There. g = 5. Milli can invite 5 guests to her party.

Calculate the area of triangle ABC with altitude, CD, given
defon

Answer:

37.5 square units

Step-by-step explanation:

Given:

A(-6,-4), B(6,5), C(-1,6), and D(2, 2), where CD is the altitude if ∆ABC

Required:

Area of ∆ABC

SOLUTION:

Area of a ∆ABC =½*AB*CD

✍️AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{6 -(-6))^2 + (5 -(-4))^2

AB = \sqrt{12^2 + 9^2}

AB = \sqrt{144 + 81}

AB = \sqrt{225} = 15

✍️CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{2 -(-1))^2 + (2 - 6)^2

CD = \sqrt{(3)^2 + (-4)^2}

CD = \sqrt{9 + 16}

CD = \sqrt{25} = 5

✍️Area of a ∆ABC =½*AB*CD

= ½*15*5

✅ Area = 37.5 square units

During a clearance sale, a discount of 33.3% is given on a dinner set marked at $2799. Find it's selling price
Mashcka [7]

First, convert the 33% to a real mathematical number. For percents, this is always done by dividing the 33% by 100%, or 33% / 100% = 0.330.

Second, find out what 33% of $2799 is. This is the amount of the sale discount. This is always found by mulitplying 0.330 by the item's cost $2799, like this:

0.330 x $2799 = $923.67.

So for this sale, you'll save $923.67 on this item.

This means, the cost of the item to you is

$2799 - $923.67 = $1875.33.

Alternatively, you can think about it this way. The item is 33% off. This means you'll pay 67.000% of the total cost (100% - 33% = 67.000%).

Now what's 67.000% of the total cost?

0.670 x $2799 = $1875.33.

Just like the result above, the sale price on the item is $1875.33.

Hope this helps you on your assignment! :)
