t each equation would take her 5 minutes to solve and each word problem would take 8 minutes. Lauren had 120 minutes to complete the final exam.
Write an inequality for each constraint. Use the

‾‾√

x

‾‾√

x

button above to type formulas with appropriate inequality symbols. (Hint: one constraint is time and the other is the number of needed items. Let x be the number of equations and y be the number of word problems solved.)

Answer:

Number of questions constraint:

x + y ≥ 15

Time constraint :

5x + 8y ≤ 120

Step-by-step explanation:

Let :

x = number of equations

y = number of word problems

Number of answers required = atleast 15

Equation takes 5 minutes

Word problem takes 8 minutes

Time available to complete exam = 120 minutes

Constraints :

Number of questions required

Total questions shout be atleast 15

x + y ≥ 15

Time constraint :

5x + 8y ≤ 120

there are 18 black socks and 12 Navy socks in your drawer the room is dark and you cannot turn on the light what is the least nu
Natasha_Volkova [10]

Answer:

3/5

Step-by-step explanation:

To have the best chance of pulling a pair with the same color you should try to get a pair of black socks. There is a 3/5 chance of pulling a black sock so this means for every 5 socks you pull you get 3 black socks or 2 navy socks. Either way you will get a pair of socks with the same color. (Double check to make sure I'm correct)

Which box-and-whisker plot represents the data set?<br><br> 11, 6, 19, 14, 21, 7, 13, 15, 15
Katena32 [7]
The box and whisker plot is attached.

We first order the data from least to greatest:
6, 7, 11, 13, 14, 15, 15, 19, 21

The median is the middle value, or 14.
The lower quartile is the median of the lower half (split by the median).  This is between 7 and 11: (7+11)/2 = 18/2 = 9
The upper quartile is the median of the upper half (split by the median).  This is between 15 and 19:  (15+19)/2 = 34/2 = 17
The highest value is 21.
The lowest value is 6.

We draw the middle line of the box at 14, the median.  We draw the left side of the box at the lower quartile, 9.  We draw the right side of the box at the upper quartile, 17.  From the right side of the box, we draw a whisker to the highest value, 21. From the left side of the box, we draw a whisker to the lowest value, 6.

What is the value of x?
tensa zangetsu [6.8K]

Answer:

X = 5°

Step-by-step explanation:

180° on a straight line.

180 - 100 = 80 angle ABC = 80°

angle ACB is vertically opposite to the 60° given

ACB = 60°

180 - 80 - 60 = 7x+5

40 = 7x + 5

7x = 35

X = 5

Lin has a scale model of a modern train. The model is created at a scale of 1 to 48. The height of the model train is 102 millil
alekssr [168]

Answer: The actual height of train = 4.896 meters.

Step-by-step explanation:

Since we have given that

Lina has a scale model of a modern train

Model is created at a scale is given by

1:48

Height of the model train = 102 millimeters

We need to find the actual height of the train.

Since there is direct variation between model and actual height of the train.

According to question,

\frac{1}{48}=\frac{102}{x}\\\\x=102\times 48\\\\x=4896\ millimeters\\\\x=4.896\ m

Hence, the actual height of train = 4.896 meters.
