Answer:

30 minutes to 40 minutes.

Step-by-step explanation:

From the graph attached,

Distance of Sabrina from her home has been given on y-axis and time taken is on x-axis.

Sabrina's walked 2 miles to reach the library in the duration = 30 - 0

= 30 minutes

She stayed at the library from 30 minutes to 40 minutes (Represented by the straight horizontal line).

Then the third segment represents the journey of Sabrina from library to home.

Therefore, Sabrina was at the library between 30 minutes to 40 minutes.

katen-ka-za [31]

Answer:

<h2>5.2 g/cm³</h2>

Step-by-step explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{57.2}{11}  = 5.2 \\

We have the final answer as

<h3>5.2 g/cm³</h3>

The price of a personal computer was 42,000 last year. If there is a decrease of
prohojiy [21]

You'll calculate the amount it was decreased by :

15% is also 15/100

15/100 * 42000

The two 0's in 100 cut 2 of the 0's in 42000 making it :

15/1 * 420

15* 420 = 6300

So, 6300 is the amount that the price is decreased by, but the question says the price of the PC (personal computer) after the decrease has happened not the price it decreased by :

So,

42000 - 6300 = 35700.

Give the numerical coefficient of the term -19x
Elenna [48]

Answer: The answer is -19.

Step-by-step explanation: We are given to write the numerical coefficient of -9x.

The given expression is a monomial with unknown variable 'x'.

We know that a numerical coefficient of a monomial is a constant multiplied to the variable(s). For example, in the term -5xy, the unknown variables are 'x' and 'y' and the numerical coefficient is -5.

Therefore, in -9x, the unknown variable is 'x' and the numerical coefficient is -9.

Thus, the answer is -9.

A drama teacher has a budget of $120 to spend on materials to create costumes for a play. She can buy 1 square yard of white mat
Neporo4naja [7]

Inequalities are used to relate unequal expressions

The greatest whole number of square yards the teacher can buy is 4

The inequality is given as:

8x + 10y \le 120

When the <em>number of square yards </em>of the white fabrics is 10.

It means that: x = 10

So, we have:

8 \times 10 + 10y \le 120

80 + 10y \le 120

Collect like terms

10y \le 120 - 80

10y \le 40

Divide both sides by 10

y \le 4

The above inequality means that:

The greatest whole number of square yards the teacher can buy is 4

Help quick please. Order the numbers from least to greatest.
Anastasy [175]

Answer:

-2\frac{1}{4}

Step-by-step explanation:

Mod of any number represents the absolute value of the number.

Therefore, |-2\frac{1}{4}|=2\frac{1}{4} = 2.25

-2\frac{1}{4}=-2.25

|1\frac{1}{4}|=1.25

\frac{3}{4}=0.75

|-1\frac{3}{4}|=1\frac{3}{4}=1.75

-1\frac{1}{4}=-1.25

Now we can arrange these numbers in ascending order.

-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25

Therefore, -2\frac{1}{4}
