i need help findind m angle 12 =?

m angle 9 = 80° and m angle 5= 68°

Answers

Answer 1

12 should equal 100°

Answer 2

Answer:

I think the answer is 12 = 100

Step-by-step explanation:

since 9 = 80 and that is the same for 11, if you do 180 - 80 = 100 which would be the answer for 10 and 12. Thus 12 = 100 based on the info given.

Hope this helps :)

Miranda is selling ice cream at the park to help raise money for the animal shelter. The amount of money she raises for the shelter (y) is proportional to the number of ice cream cones (x) she sells. If Miranda wants to raise $250 for the shelter, how many ice cream cones would she need to sell?

Answers

Answer:

The question is lacking the detail of the price of the ice cream cones.

Assuming the ice cream cones cost $2 each then she would have to sell;

= 250/2

= 125 ice cream cones

If she sells 125 ice cream cones, she will be able to raise $250 if the cones are sold at $2 each.

The perimeter of a rectangle is 40 inches. If the length of the rectangle is 15 inches, which equation could be used to find the width, x?
OA. x + 2(15) = 40
OB. 15(x + 2) = 40
O.Cx+ 15 = 40
OD. 2(x + 15) = 40

Answers

A N S W E R :

Perimeter of rectangle = 40 inchesLength of rectangle = 15 inches

Let the required Breadth of rectangle be 'x' inches

Perimeter of rectangle is calculated by the given below formula :

Perimeter = 2(Length + Breadth)

Now, substitute the given values in above formula :

→ 40 = 2(15 + x)

Hence,the option (d) 2(x + 15) = 40 is the correct answer.

At her restaurant, Violet opened 285 cans of tomato sauce. She needs to use 4 cans of sauce for one pan of lasagna. How many pans of lasagna could Violet make if she uses all of the cans? Write the answer as a mixed number.

Answers

Answer:

71 1/4 pans of lasagna

Step-by-step explanation:

From the above question:.

4 cans of tomato sauce = 1 pan of lasagna

285 cans of tomato sauce = x

Cross Multiply

4x = 285 × 1

x = 285/4

x = 71 1/4 pans of lasagna

Violet could make 71 1/4 pans of lasagna

Help me classify the triangles by its sides and measuring its angles :)

Answers

Answer:

Triangle 1: Isosceles obtuse

Triangle 2: Right scalene

Step-by-step explanation:

Isosceles triangles have two congruent sides and two congruent angles. Triangle one fits this description because the double markers on sides AC and AB indicate that the two sides are congruent.

Obtuse triangles have an angle that is larger than 90 degrees. Triangle one fits this description as indicated by angle A. If it were a right angle, it would have a square symbol (as shown in triangle 2). The other two angles are obviously smaller, and they would be acute angles.

Right triangles have an angle that is exactly 90 degrees. Right triangles will have a square to indicate that it has this measurement.

Scalene triangles have three different measurements for its sides and its angles.

O Line p must be drawn in the same plane as line n.

Answers

Answer: C: Line p must be drawn so that it can lie in the same plane as line l

Step-by-step explanation: edge 2020

Line p must be drawn so that it can lie in the same plane as line l.

Option C is correct.

What is Coordinate Geometry?

One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.

As per the given data:

A new line, p, is drawn parallel to line I.

We have to find that which of the statements from the given options in the question are true.

It was discovered that the specified set of lines consisted of plane A having line m and plane B having line n. Lines m and n are orthogonal to one another.

The new line l has been created parallel to line p in accordance with the planes. It has been possible for line p to cross the plane B. Line l has therefore also been intersecting plane B.

The line p has been drawn such that it is on the same plane as the line l since a line cannot cross its own plane. Option C is right as a result.

Hence, Line p must be drawn so that it can lie in the same plane as line l.

A bird traveled a horizontal distance of 300ft over a distance that rose 150ft what is the angle of elevation that the bird made with the ground . Round to the nearest tenth

Answers

Answer:

26.56 degrees

Step-by-step explanation:

The set up will give a right angles triangle

Given

The Horizontal distance = Adjacent side = 300ft

The height = Opposite side = 150ft

Using the SOH CAH TOA identity;

tan theta = opposite/adjacent

tan theta = 150/300

tan theta = 1/2

theta = arctan 1/2

theta = 26.56 degrees

Hence the angle of elevation is 26.56 degrees

A table saw is on clearance for 20% off. If the sale price of the table saw is $380, what was the original price? Justify your solution. Round to the nearest cent if necessary.

Answers

20% off means it is selling for 80% of the original price ( 100% - 20% =80%)

Divide the sale price by 80% as a decimal:

380/0.80 = 475

The original price was $475

Justify:

Multiply the original price by 20% and subtract:

475 x 0.20 = 95

475-95 = $380 which is the sale price.

Answer:

Step-by-step explanation:

20% off means it is selling for 80% of the original price ( 100% - 20% =80%)

Divide the sale price by 80% as a decimal:

380/0.80 = 475

The original price was $475

Justify:

Multiply the original price by 20% and subtract:

475 x 0.20 = 95

475-95 = $380 which is the sale price.

Willie and Pedro are reading the same book. Willie read 108 pages in 3 hours, and Pedro read 160 pages in 5 hours. How many more pages per hour did Willie read?

Answers

Answer:

4 pages per hour

Step-by-step explanation:

Willie and Pedro are reading the same book. Willie read 108 pages in 3 hours, and Pedro read 160 pages in 5 hours.

We find how many pages per hour each of them read.

For Willie

Willie read 108 pages in 3 hours,

3 hours = 108 pages

1 hour = x

Cross Multiply

3x = 108 pages × 1 hours

x = 108 pages/3

x = 36 pages per hour

For Pedro

Pedro read 160 pages in 5 hours

5 hours = 160 pages

1 hour = x

Cross Multiply

5x = 160 pages × 1 hours

x = 160 pages/5

x = 32 pages per hour.

How many more pages per hour did Willie read?

This is calculated as:

36 pages/hour - 32 pages per hour

= 4 pages per hour
