1a) To find the total area, you must find the area of the triangular part that is missing, then subtract this from the area of the rectangle. For the triangle’s area, you need to know the width (2m) and length (2m). For the rectangle’s area you need to know the width (3m) and length (4m).
1b) the total area is 10m^2 (10 meters squared). This is found by subtracting the triangle (.5x2x2=2) from the rectangle (3x4=12).

What type of triangle is this triangle?

acute scalene

obtuse isosceles

obtuse scalene

acute isosceles

Answers

Answer:

Obtuse scalene

Step-by-step explanation:

Answer:

obtuse scalene

Step-by-step explanation:

Scalene means that none of the sides are equal.

Isosceles means that two of the sides are equal.

Obtuse means an angle in the triangle is larger than 90 degrees.

Acute means all angles in the triangle are smaller than 90 degrees.

None of the sides are equal so this triangle has to be scalene and the angle in the bottom right is larger than 90 degrees so this triangle is obtuse.

Hope this helps! :)

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.

Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?

350 m/s

355 m/s

360 m/s

365 m/s

Answers

Answer:360 m/s

Step-by-step explanation:

The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

As we can see in the graph:

When the air temperature is 10°C the speed of sound is around 337m/s

When the air temperature is 20°C the speed of sound is around 344m/s

When the air temperature is 30°C the speed of sound is around 348m/s

When the air temperature is 40°C the speed of sound is around 355m/s

From the above observation, the air temperature increases the speed of the sound increases.

So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.

Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

Choose all of the correct statements.

Answers

Answer:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

Step-by-step explanation:

Diameter (d) of a circle is 2 times the radius (r). Mathematically, it is written as:

d = 2r

From:

d = 2r

Divide both side by 2

r = d/2

The radius is half the diameter.

Circumference (C) of a circle is given by:

C = 2πr

C = π2r

Recall:

d = 2r

C = πd

C = πd

Divide both side by d

π = C/d

C = πd

Divide both side by π

d = C/π

C = πd

π = 3.14

C = 3.14 × d

Thus, the circumference is 3.14 times the diameter.

SUMMARY:

The correct statement from the above illustration is given below:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

A salesperson at a jewelry store earns 8% commission each week....

Answers

Answer:

heidi earned $56 in commision.

hyou take the amount the jewerly store made, 700 in this case and divide it by 100, to find what 1% is. so 1% is 7$, multiply that  by 8, since she makes 8% and that ur answer

Step-by-step explanation:

Ok so 700x0.8 will give 80% and divided by 10=8% the salesperson will earn $56 the total is out of 100,100-8= the amount the jewelry store gets meaning the remaining of the $700,700-56=644. To conclude the salesperson will get $56 and the jewelry store will get $644. Hope this helps :)
