This is a false statement.

When you are solving using square roots, you need to be aware that answers can be both positive and negative. When we solve this, you see there are two possible answers.

x^2 - 9 = 0

x^2 = 9

x = +/- 3

While 3 is an answer, so is -3. If we square either of those numbers, we get 9, which will satisfy the equation.

Amanda's sewing a flag for a competition. The dimensions of her flag are shown below. Approximately, how many square yards of bl
DedPeter [7]

To calculate the area of the black material on the flag, we need the shape and the dimensions of the black material itself.

<em>Since the question is incomplete, as the dimension of the flag and the dimension of the black material are not given, I will provide a general explanation</em>

<em />

Assume the shape of the black material is a rectangle.

The area will be calculated as:

Area = Length * Width

Take for instance;

Length = 4yd;\ Width = 5yd

The area is:

Area  = 4yd * 5yd

Area  = 20yd^2

Assume the shape of the black material is a square.

The area will be calculated as:

Area =Length^2

Take for instance;

Length = 4yd

The area is:

Area = (4yd)^2

Area = 16yd^2

Assume the shape of the black material is a triangle

The area will be calculated as:

Area = 0.5 * Base * Height

Take for instance;

Base = 4yd;\ Height = 5yd

The area is:

Area = 0.5 * 4yd * 5yd

Area =10yd^2

So, in general.

You need to first get the shape of the black segment on the flag, then calculate the area using the appropriate formula.

Whats the answer is for math btw fidsf
ra1l [238]

Step-by-step explanation:

Since this is a select as many answers that are right, there are obviously many answers that are correct.

First, you get m by itself, so you divide 6 with 300.

So,

6m < 300

___   ___

 6        6

m < 50

So the answers are numbers less than 50.

Which are the first four answers:

A, B, C, D

A spirit shop outside the hockey stadium sells merchandise representing the three school districts that built the arena. The ent
Leokris [45]

The statue should be located at point E. Point E is the center of the circumscribed circle of the triangle created by the entrances to the arena, the spirit shop, and the parking lot. The distance from the statue to each vertex will then be equal to the radius of the circumscribed circle, so the statue will be at the same distance from all three landmarks.

The symphonic choir and the jazz choir are recording songs for an album. The album can be no more than 72 minutes long. The jazz
zimovet [89]

Answer:

The symphonic choir can record a maximum of 14 songs.

Step-by-step explanation:

We know that the album cannot be more than 72 minutes long, and the jazz choir records a total of 7 (3min) = 21  song minutes.

If we call c the number of songs the symphonic choir records , and each song is 3.5 minute long, then the song minutes for the symphonic choir are 3.5c; therefore, we have the inequality

3.5c+21\leq 72<em> (this says the song minutes for jazz choir plus song minutes for symphonic choice cannot exceed 72 minutes )</em>

We solve this inequality by subtracting 21 from both sides and then dividing by 3.5:

3.5c\leq 51

$c\leq \frac{51}{3.5} $

c\leq 14.47

The maximum integer value c can take is 14; therefore, the maximum number of songs the symphonic choir can record is 14 songs.

I need help with 7 and 4 and 9 also 10 <br><br><br> I will give the most higher points I got
Serga [27]
7. 9/5 = 1 4/5
*When multiplying with a whole number u can turn it into a fraction by putting a one under it
So 3/1 times 3/5 = 9/5
*just multiply straight across

4. 2/1 times 1/4 = 2/4 = THEN SIMPLIFY = 1/2

9. 3/4 times 3/1 (cups)
*multiply straight across
9/4 = 2 1/4 (cups of sugar)
So she uses less than 3 cups to make all 3 loaves

* 10. Sorry I can’t tell if it says 5/6 on both of them
If it says 5/6 on both of them then the answer is obvious and she worked more than that over the course of 2 days

* 10. It must be a 5/9 on the second one
So if so
5/6 times 2/1 (days)
10/6 then we need to multiply the 6 denominator (bottom of the fraction) with something to = 9 denominator
9 divided by 6 = 1.5
10/6 times 1.5 for both the numerator (top) and denominator (bottom)
= 15/9 (simplified 1 6/9)
This one she exercised more than 5/9
