Caroline has 1/2 pound of seeds to divide into 8 equal-sized portions.

1/2 divided by 8 = 1/2  *  1/8 = 1/16

Each friend gets 1/16 of a pound of seeds.

Answer: A) 1/16 lb.

If you would like to know how much will each packet of seeds weight, you can calculate this using the following steps:

1/2 pound of flower seeds divided by 8 equal size packets of flower seeds:
1/2 / 8 = 1/(2*8) = 1/16 lb

The correct result would be A. 1/16 lb.

What is X if
umka2103 [35]

Answer:

X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}

Step-by-step explanation:

\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix} +X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}

X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}-\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix}

X = \begin{bmatrix} - 5-(-1) & - 1-(-2)\\ 2-4 & 1-8\end{bmatrix}

X = \begin{bmatrix} - 5+1 & - 1+2\\ 2-4 & 1-8\end{bmatrix}

X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}

child admission is $5.90 and adult admission is $9.10 . 175 tickets were sold for a total sales of $1282.10 . How many child tic
GenaCL600 [577]

Answer:

Child tickets are 97

Step-by-step explanation:

x + y = 175 ...............(1)

x = 175 - y

5.90x + 9.10y = 1282.10. .........(2)

5.90 (175 - y) + 9.10y = 1282.10

1032.50 - 5.9y + 9.10y = 1282.10

3.2y = 249.60

y = 249.6. / 3.2

y = 78

From equation 1

x + y = 175

x + 78 = 175

x = 175 - 78

x = 97

A number that has a digit in the tenths place,hundredths place,or beyond
nadya68 [22]
A number that has a digit in the tenths place, hundredths place or beyond is called decimal numbers. Any number after the decimal point is called decimal number, it value always started in tenths place value, then followed by hundredths, then thousandths, then ten thousandths, then hundred thousandths and so on. It is still the same with giving place value in whole number. The only difference is, its value decreases as it becomes away from the decimal point.

Determine the value of (tangent of 88 degrees, 22 minutes, and 45 seconds). In this case, minutes are 1/60 of a degree and secon
mariarad [96]

Answer:

  c.  35.34015106

Step-by-step explanation:

As with many problems of this nature, you only need to get close to be able to choose the correct answer. 22 minutes 45 seconds is just slightly less than 1/2 degree (30 minutes), so the tangent value will be just slightly less than tan(88.5°) ≈ 38. The appropriate choice is 35.34015106.

If you need confirmation, you can find tan(88°) ≈ 29, so you know the answer will be between 29 and 38.

__

The above has to do with strategies for choosing answers on multiple-choice problems. Below, we will work the problem.

The angle is (in degrees) ...

  88 + 22/60 +45/3600 = 88 + (22·60 +45)/3600 = 88 +1365/3600

  ≈ 88.3791666... (repeating) . . . . degrees

A calculator tells you the tangent of that is ...

  tan(88.3791666...°) ≈ 35.3401510614

Many calculators will round that to 10 digits, as in the answer above. Others can give a value correct to 32 digits. Spreadsheet values will often be correct to 15 or 16 digits.

allsm [11]

Answer:

-459 2/9

Step-by-step explanation:

calculate 34-99= -65

and turn 2 7/9 into a mixed number as 25/9

leaves u with

7(-65)-7+25/9

multiply 7x-65=-455

-455-7+25/9

-462+25/9

get common denomionator and add

-4133/9 or -459 2/9 or -459.2
