rachel uses grid paper to plan a mural to paint at her school. the design will be made of two connected rectangles. the larger rectangle will have an area between 35 square feet and 45 square feet. the smaller rectanglewill have an area between 10 square feet and 20 square feet. Draw and label a diagram to show what Rachel could plan. Explain how to find the total area.

Answers

Answer 1
The picture attached has two rectangles drawn side by side. The larger one has an area of 40 square feet (8 x 5), and the smaller one has an area of 10 ft.² (2 x 5).

To find the total area, you add these areas together. In math when you put two things together like in the picture, this is showing addition.

The total area represented is 50 ft.².

Which kind of pollution is shown in the image?
A: point source
B: nonpoint source
C: carbon source
D:natural resource

Answers

A - Point Source

This is the answer as a point source is defined as pollution that could come out of varying things which includes a pipe - thus what is depicted within the image. A point source is also pollution which you can detect the source from - non-point source being the opposite.

What is the size of the obtuse angle CBA

Answers

Answer:

[tex]m<CBA=102\°[/tex]

Step-by-step explanation:

we know that

The internal angle of an equilateral triangle is equal to [tex]60\°[/tex]

The internal angle of a square is equal to [tex]90\°[/tex]

To find the internal angle of a regular pentagon, apply the formula

[tex]S=[(n-2)180\°]/n[/tex]

where

n is the number of sides (n=5)

substitute

[tex]S=[(5-2)180\°]/5=108\°[/tex]

therefore

In this problem

[tex]m<CBA+60\°+90\°+108\°=360\°[/tex]

[tex]m<CBA+258\°=360\°[/tex]

[tex]m<CBA=360\°-258\°=102\°[/tex]

The correct answer is A) 2x+5.

Completing the synthetic division, first bring down the leading coefficient:

       2  5

Multiply the 5 by the -1:

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 = 55

Therefore, 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 = 55

Therefore, P(green and green) = (1/55) * (1/11) = 1/605

which expression gives the length of pq in the triangle shown below?

Answers

For this case what we should do is use the Pythagorean theorem.
 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
We have to use the Pythagorean theorem.
 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.

How many cubic centimeters of water can this paper cone cup hold?

Answers

Final answer:

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.

A new patio will be an irregular hexagon. The patio will have two long parallel sides and an area of 360 square feet. The area of a geometrically similar patio is 250 square feet, and it’s long parallel sides are 12.5 feet apart. What is the corresponding distance on the new patio

Answers

The length of the new patio will be evaluated as follows:
The area scale factor=(area of new patio)/(area of original patio)
=360/250
=36/25
but
Linear scale factor=√(area scale factor)
Linear scale factor=√(36/25)=6/5
thus the length of the patio will be:
length=(linear scale factor)*(length of the original patio)
=6/5×12.5=15 ft

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.

Final answer:

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.

Answers

The answer is 1/4. To find this, add all the frequencies together, then you get 12. Then add B and C together to get 4. Divide 12 by 4 and get 1/4.

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].

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

x= score of 4th game

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.
