1/8 of the brass instruments are too if there are 240 instruments in the band how many are tubas

Artemon [7]

Well, just by looking at the beginning of the problem, Jamelia had made the common mistake of thinking that
$\sqrt{72}$ (<span>8.4852...)
</span>is equal to
$2* \sqrt{36}$ (12)

If you want to estimate a square root like 72, simply find squares that would fit around the number you are looking to find, in our case, 72.

So 9*9 is 81, which is too high and 8*8 is 64, which is too low. So you know that somewhere between those numbers is what your root of 72 is!

Amanda placed her finger on the origin of a regular coordinate plane. She marked a point after moving her finger 1 unit to the l

Lubov Fominskaja [6]

Answer:

( x , y ) = ( -1 , - 5 )

Step-by-step explanation:

Solution:-

- The rectangular coordinate system ( Cartesian ) is defined by two independent variables namely, "x and y".

- The values of both varibales lie on the horizontal and vertical line respectively, ( x & y ).

- The values on the horizontal axis also known as the x-axis is marked with a referece of x = 0 ( origin ). All the values to the right of the point of origin are denoted as positive units and all values to the left of the point of origin are denoted as negative units.

- Similarly, The values on the vertical axis also known as the y-axis is marked with a referece of y = 0 ( origin ). All the values to the above the point of origin are denoted as positive units and all values below of the point of origin are denoted as negative units.

- The axis are conventionally oriented such that 90 degrees angle is formed in between them and always denoted in the counter-clockwise direction.

In other words, if +x is pointing to the right then the +y will be pointed in the direction when +x is rotated counter clockwise to 90 degrees; hence, points upward.

- When Amanda starts off at the origin she is at the order pair ( 0 , 0 ).

- She then moves her finger 1 unit to left ( -x ) and 5 units down ( -y ). Hence, she moves 1 unit along the -x direction and then moves 5 units down along -y direction.

Hence, she is at an ordered pair ( x , y ) = ( -1 , - 5 ) .

3

Step-by-step explanation:

3 (miles) × 5 (days) = 15 (Run)

3 (miles) × 5 (days) = 15 (Bike)

30 miles total

Hope this helps!!

Check:

She works out twice a day and goes three miles each time for five days.

Six miles per day

6 · 5 = 30

What is 3 1/3 as a percent?

Nikitich [7]

Answer:

$333.3\%$

Step-by-step explanation:

We want to express 3⅓ as a percentage.

Let us first of all rewrite 3⅓ as decimals to obtain:

$3 \frac{1}{3} = 3.3333...$

To express this as a percentage, we multiply by 100%

$3 \frac{1}{3} = 3.3333... \times 100\%$

This multiplies to give us:

$3 \frac{1}{3} = 333.3\%$
