(a) Mary and Cynthia were building a cone-shaped sand castle. After some time, the diameter of
the sand shaped cone was 14 in. and the height was 15 in. What is the appoximate volume of the
sand cone rounded to the nearest tenth? (Show work!!) PLEASE HELP!

Answers

Answer:

[tex]\displaystyle V\approx 769.7\text{ in}^3[/tex]

Step-by-step explanation:

We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.

The volume for a cone is given by:

[tex]\displaystyle V=\frac{1}{3}\pi r^2h[/tex]

Where r is the radius and h is the height.

Since the diameter is 14, the radius is 7.

And we are given that the height is 15.

Therefore, the volume will be:

[tex]\displaystyle V=\frac{1}{3}\pi (7)^2(15)[/tex]

Use a calculator:

[tex]\displaystyle V\approx 769.7\text{ in}^3[/tex]

The volume of the cone is approximately 769.7 cubic inches.

In ΔTUV, the measure of ∠V=90°, the measure of ∠T=52°, and UV = 7 feet. Find the length of VT to the nearest tenth of a foot.

Answers

Answer:

5.5 feet

Step-by-step explanation:

Answer:

5.5 feet

Step-by-step explanation:

We have VT adjacent to angle T.

We know that VU, side length that is opposite to T, is 7.

We use the TAN function, which is opposite/adjacent, on T :)

tan(52) = 7/x

x tan(52) = 7

x = 7/tan(52) =~ that's around 5.469 --> 5.5 feet

Jackie correctly solved this equation:
4/x-2+1/x^2-4=1/x+2
Which statement describes the solutions she found?

Answers

Answer:

answer is A

Step-by-step explanation:

took the test :)

The option (A) she found one valid solution and no extraneous solution is correct, and x = -11/3 or -3.66.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have the equation:

[tex]\rm \dfrac{4}{x-2}+\dfrac{1}{x^2-4}=\dfrac{1}{x+2}[/tex]

After taking LCM

4x + 9 = x - 2

x = -11/3

or

x = -3.66

Thus, option (A) she found one valid solution and no extraneous solution is correct, and x = -11/3 or -3.66.

A group of five students have a mean test score of "34.2." Another student has a score of 50. What is the mean average of all "six" students?

Answers

Answer:

The mean average of all "six" students is 36.83.

Step-by-step explanation:

Mean:

The mean is the sum of all scores divided by the number of scores.

A group of five students have a mean test score of "34.2." Another student has a score of 50.

This means that the sum is given by:

[tex]S = 5*34.2 + 50 = 171 + 50 = 221[/tex]

What is the mean average of all "six" students?

Sum of 6 students is 221. So

[tex]M = \frac{221}{6} = 36.83[/tex]

The mean average of all "six" students is 36.83.

Answer:

20 cubic feet.

From feet: length (ft) × width (ft) × height (ft) = cubic feet.

From inches: length (in) × width (in) × height (in) ÷ 1728 = cubic feet.

From yards: length (yd) × width (yd) × height (yd) × 27 = cubic feet.

I hope this will help u

Step-by-step explanation:

Each interior angle of a regular polygon = 140 deg. So each exterior angle of the regular polygon = 180-140 = 40 deg. Hence the regular polygon has 360/40 = 9 sides.

find the square root of 14+6√5​

Answers

Answer:

3 + √5

Step-by-step explanation:

Find the square root of 14+6√5​

Change to √ ( 14 + 6√5 ) = √x + √y

1️⃣ Square.

14 + 6√5 = x + y + 2√xy

14 + 2√45 = ( x + y) + 2√xy

2️⃣ Compare.

(x + y) = 14

xy = 45

3️⃣ Solve.

(x - y)² = (x+y)² - 4xy

( x - y)² = 14² - 180

( x - y)² = 196 - 180

( x - y)² = 16

( x - y) = 4

x + y = 14

x - y = 4

2x = 18

x = 9 .

y = 5 .

14 + 6√5 = √9 + √5 = 3 + √5 .

Answer: 3 + √5 .
