Liszt had test scores of : 72, 94, 108, 60

what is the range for her test scores

Answers

Answer 1

Answer: 48

Step-by-step explanation: The range is the difference between the greatest number in the data set and the least number in the data set which in this case is 108 - 60 or 48. So the range of this data set is 48.

Brisa's kite is flying above a soccer field at the end of 43 m of string. If the angle of elevation to the kite measures 72degree, and Brisa is holding the kite 1.2 m off the ground. How high above the ground is the kite flying? (Round to the nearest meter)

Answers

Answer:

The height the kite is flying above the ground level to the nearest meter is 42m.

Step-by-step explanation:

this is not drown to scale:

  |\

  |  \

x |   \   43m

  |    \

  |___\

         Angle is 72º

sine = opposite / hypotenuse

sin 72 = x / 43

0.9510565 = x / 43

therefore x = 40.9m

Brisa is holding the kite 1.2 m off the ground, we also need to add 1.2 m to our calculated height of the kite. Thus, the answer is  

           40.9 m + 1.2 m = 42.1 m to the nearest meter is 42m.

centimeters?
Your answer

Answers

The volume of a container with a radius of 4 centimeters and a height of 4  centimeters is 67.2 cubic centimeter

Solution:

The volume of a container varies jointly with the square of its radius, r, and its height, h

Therefore,

[tex]v \propto r^2 h\\\\v = k \times r^2h -------- eqn\ 1[/tex]

The  container has a height of 10 centimeters, and radius of 6 centimeters, and a volume of 377 cubic  centimeters

Substitute v = 377 and h = 10 and r = 6 in eqn 1

[tex]377 = k \times 6^2 \times 10\\\\377 = k \times 360\\\\k = 1.047 \approx 1.05[/tex]

What is the volume of a container with a radius of 4 centimeters and a height of 4  centimeters?

Substitute k = 1.05 and r = 4 and h = 4 in eqn 1

[tex]v = 1.05 \times 4^2 \times 4\\\\v = 1.05 \times 16 \times 4\\\\v = 67.2[/tex]

Thus volume of a container with a radius of 4 centimeters and a height of 4 centimeters is 67.2 cubic centimeter

Answers

Answer:

No, the point (273, 2) does not lie on the circle that is centered at the origin and contains the point (0, -4)

Step-by-step explanation:

The circle centered at the origin that contains the point (0,-4) has equation:

[tex] {x}^{2} + {y}^{2} = 16[/tex]

If the point (273,2) lies on this circle , then it must satisfy this equation:

The area of the figure is A. 216 cm².

Step-by-step explanation:

Step 1:

To calculate the value of the composite shape we first divide it into shapes that we know.

In this case, the composite figure consists of a rectangle and a triangle attached to it.

If we can calculate the individual areas of the two shapes we should be able to calculate the area of the composite shape.

Step 2:

The triangle has a base length of 8 cm and a height of 12 cm. The area of the triangle [tex]=\frac{1}{2} (b)(h)=\frac{1}{2} (8)(12) = 48.[/tex]

The area of the triangle is 48 cm².

Step 3:

The area of a rectangle is the product of its length and its width.

The given rectangle has a length of 14 cm and a width of 12 cm.

The area of the rectangle [tex]= (l)(w) = (14)(12) = 168.[/tex]

The area of the rectangle is 168 cm².

Step 4:

Now we calculate the area of the entire figure by adding the areas of the triangle and the rectangle.

Area of the figure [tex]=48+168 = 216.[/tex]

So the area of the figure is 216 cm² which is option A.

Eduardo earns a base salary of $30,000 per year and earns $1,875 per car he sells. Which equation can be used to find the number of cars, c, that Eduardo sold in a year he made 46,875 ?

Answers

Answer:

The equation is, A =30,000 + 1875n.

He sold 9 cars the year he made that amount of money.

Step-by-step explanation:

Before calculating, let's assign letters to certain variables:-

✓ let "A" be used to represent the total amount earned after adding his base salary to the amount he earned as commission per car he sells.

✓ "P" will be used to represent his base salary (a constant = 30,000)

✓ "n" will represent the number of cars sold within a given year.

✓ "B" will be used to represent his commission per car he sells.

Fixing them into a formula, we have:

A = P + n(B)

Since "P" and "B" are constants of 30000 and 1875 respectively, we substitute the letters for their actual amount in the formula:-

A = 30,000 + n(1875)

A = 30,000 + 1875n +This is now the equation that can be used to calculate the number of cars he sold in the year he earned 46,875).

So, since "A" is now $46,875, we substitute accordingly to find the number of cars he sold in the year he earned such amount.

46,875 = 30,000 + 1875b

1875n = 46,875 - 30,000

1875n = 16875

n = 16875/1875

n = 9 cars

Therefore the equation to be used to determine how many cars he sold when he earned $46,875 is:

A = 30,000 + 1875n

He sold 9 cars the year he earned $46,875.

Carson went to pick apples at an orchard.he gave one-third of his apples to his friend Nathan.then he gave one-half of what he had to his friend Nikki.on his way home he dropped one-fourth if what he had left,so that he only had 9 for him and his family.how many apples did Carson pick originally?

Answers

Answer:

36 apples

Step-by-step explanation

Step 1  = he dropped 1/4  and was left with 9  

Finding 1/3 one third of 9 = 3.

Then 9 +3 = 12

Step 2 He parted with 1/2 and was left with 12

12x2=24

Step 3 He parted with 1/3 and was left with 24

= 12+ 12 + 12  = 36    Where 1/3 of 36 = 24

Answer = 36

Answer:

36

Step-by-step explanation:

Carson had x number of apples to start with.

He gave 1/3 to Nathan. Now Carson has (2/3)x apples left.

He gave 1/2 of what was left to Nikki. Now Carson has (1/2)(2/3)x = (2/6)x = (1/3)x apples.

On the way home, he dropped 1/4, so he has 3/4 of the last amount he had, and the number is 9.

(3/4) * (1/3)x = 9

3/12 x = 9

1/4 x = 9

x = 36

Answer: He picked 36 apples.

Check:

Start with 36 apples.

Give 1/3 to Nathan. Now Carson has 24 apples.

Give 1/2 to Nikki. Now Carson has 12 apples.

Drop 1/4. 1/4 of 12 is 3. 12 - 3 = 9.

Hew only had 9 apples left, so 36 is correct.

The mode of a data set is the number that appears most often.

So the mode of this set would be 33, since it appears twice.

The mean of a data set is the average of the numbers.

To find the mean (average), add all eight numbers together, then divide by eight...

31 + 29 + 33 + 37 + 43 + 38 + 33 + 40 = 284

284 / 8 = 35.5

So, the mean of the numbers is 35.5!
