which expression gives the length of pq in the triangle shown below?
Answers
We have then:
PQ ^ 2 = 15 ^ 2 + 19 ^ 2
Clearing we have:
PQ = root (15 ^ 2 + 19 ^ 2)
Answer:
The expression used to find PQ is given by:
PQ = root (15 ^ 2 + 19 ^ 2)
option C
So it will be:
PQ ^ 2 = 15 ^ 2 + 19 ^ 2
PQ = root (15 ^ 2 + 19 ^ 2)
So the expression used to find PQ is given by:
PQ = root (15 ^ 2 + 19 ^ 2)
So the answer would be letter C.

Karen spends 450 on monthly bills.of this total amount,12% is for phone service,1/10 is internet service,2/9 is for utilities.id the rest of the amount is for food ,how much does Karen have for
Answers
how much does Karen have for food?
For this case, we have that the full amount of money is:
12/100 + 1/10 + 2/9 + x = 1
Where,
x: fraction of money for food
Clearing x we have:
x = 1 - (12/100 + 1/10 + 2/9)
Rewriting:
x = 251/450
Thus, the amount of money for food is:
450 * x = 450 * (251/450) = 251
Answer:

7. Two lines that intersect to form right angles are called what? A. Perpendicular lines B. Parallel lines C. Line segments D. Skew lines
Answers
The answer to the above question can be explained as -
Perpendicular lines are the lines that intersect each other or meet each other at 90 degrees, thus form a right angle.
The parallel lines are the lines that do not meet each other.
Thus, the answer to -
"Two lines intersect each other to form right angles are called" is - A. Perpendicular Lines.
Perpendicular lines are two lines that intersect each other forming a right angle (90 degrees). They are different from parallel lines (which do not intersect), line segments (parts of a line with two endpoints), and skew lines (non-intersecting and non-parallel lines in different planes).
Explanation:The correct answer is A. Perpendicular lines. Perpendicular lines are two lines that intersect each other at right angles, which means they form a 90-degree angle. This kind of intersection is common in geometry, and you will encounter it frequently in your studies. This contrasts with parallel lines, which do not intersect at all, and line segments, which are parts of a line with two endpoints. Skew lines are lines that do not intersect and are not parallel, usually because they exist in different planes.

When Sally went bowling her scores were 108, 72, and 95. If she bowls a 4th game, what will her score need to be to give her an average of 91?
Answers
Add the 4 scores, divide by 4 and set it equal to 91
(108 + 72 + 95 + x)/ 4= 91
multiply both sides by 4 to eliminate fraction
108 + 72 + 95 + x= 364
275 + x= 364
subtract both sides by 275
x= 89
ANSWER: The scored needed for the fourth game is 89.
Hope this helps! :)
To achieve an average score of 91, Sally needs to bowl an 89 in her fourth game, calculated by subtracting her current total score of 275 from the desired total of 364 points.
To calculate the score Sally needs in her fourth game to achieve an average of 91, we first need to determine the total points she needs after four games. We can calculate the required total points by multiplying the desired average score by the number of games:
91 × 4 = 364 total points
Next, we add up the scores from Sally's first three games:
108 + 72 + 95 = 275 points
Finally, we subtract the sum of her first three games from the total required points to find the score Sally needs in her fourth game:
364 - 275 = 89 points
Therefore, Sally needs to bowl a score of 89 in her fourth game to achieve an average of 91.

Calculate the probabilities of selecting specific pairs of blouses from Maddie's closet with different colors.
Explanation:1. P(black and yellow):
Number of ways to select 1 black blouse out of 4 black blouses = 4Number of ways to select 1 yellow blouse out of 2 yellow blouses = 2Total number of ways to select 2 blouses out of 11 blouses = 11C2 = 55Therefore, P(black and yellow) = (4/55) * (2/11) = 8/605
2. P(green and green):
Number of ways to select 2 green blouses out of 2 green blouses = 1Total number of ways to select 2 blouses out of 11 blouses = 11C2 = 55Therefore, P(green and green) = (1/55) * (1/11) = 1/605

The internal angle of a square is equal to [tex]90\°[/tex]
To find the internal angle of a regular pentagon, apply the formula

The table shows the results of spinning a spinner several times. (Don’t mind my answer)
Answers
The experimental probability of spinning a B or a C is [tex]\( \frac{1}{4} \)[/tex].
To find the experimental probability of spinning a B or a C, we need to sum up the frequencies of outcomes B and C and then divide that by the total number of spins.
Given frequencies:
Outcome A: 3
Outcome B: 2
Outcome C: 1
Outcome D: 4
Outcome E: 2
Total frequency of B and C: 2 (from outcome B) + 1 (from outcome C) = 3
Total number of spins: Sum of all frequencies = 3 + 2 + 1 + 4 + 2 = 12
Experimental probability of spinning a B or a C: [tex]\(\frac{\text{Total frequency of B and C}}{\text{Total number of spins}} = \frac{3}{12} = \frac{1}{4}\)[/tex]
So, the experimental probability of spinning a B or a C is [tex]\(\frac{1}{4}\)[/tex].

How many cubic centimeters of water can this paper cone cup hold?
Answers
To determine the number of cubic centimeters of water that the paper cone cup can hold, calculate the volume using the formula for the volume of a cone, and then convert it to cubic centimeters.
Explanation:To calculate the number of cubic centimeters of water the paper cone cup can hold, we need to first determine its volume. The volume of a cone can be calculated using the formula V = (1/3) π r² h, where V is the volume, π is the mathematical constant pi, r is the radius of the base of the cone, and h is the height of the cone.
Once we have the volume of the cone, we can convert it to cubic centimeters since the dimensions given are in centimeters. Finally, we can determine the number of cubic centimeters of water the paper cone cup can hold.
For example, if the cone has a radius of 5 cm and a height of 10 cm, the volume would be:
V = (1/3) π (5 cm)² (10 cm)
V = (1/3) π (25 cm²) (10 cm)
V = (1/3) π (250 cm³)
V ≈ 261.79 cm³
Therefore, the paper cone cup can hold approximately 261.79 cubic centimeters of water.
