Determine if the side lengths given form a triangle. Justify your response. 6.4 mm, 12.9 mm, 14.2 mm

Answers

Answer:

Step-by-step explanation: Yes I think since if you add 12.4 and 6.4 your answer is more then 14.2 so yes it is possible

Answer:

Yes, it does form a triangle

Step-by-step explanation:

According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that the given side lengths DO form a triangle. 6.4+12.9=19.3 which is more than 14.2.

a solid metal cone with radius of base 12 cm and height 24 cm is melted to form spherical solid balls of diameter 6 cm each. Find the number of the balls thus formed​

Answers

Answer:

32 solid balls are formed.

Step-by-step explanation:

Let suppose that volume of the cone is equal to the total volume of balls, of which we derive the following formula:

[tex]\frac{1}{3}\cdot \pi\cdot R^{2}\cdot h = \frac{1}{6}\cdot \pi \cdot n \cdot D^{3}[/tex] (1)

Where:

[tex]R[/tex] - Radius of the base of cone, measured in centimeters.

[tex]h[/tex] - Height of cone, measured in centimeters.

[tex]D[/tex] - Diameter of sphere, measured in centimeters.

[tex]n[/tex] - Number of balls, no unit.

Then, we clear the number of balls:

[tex]2\cdot R^{2}\cdot h = n\cdot D^{3}[/tex]

[tex]n = \frac{2\cdot R^{2}\cdot h}{D^{3}}[/tex]

If we know that [tex]R = 12\,cm[/tex], [tex]h = 24\,cm[/tex] and [tex]D = 6\,cm[/tex], then the number of balls is:

[tex]n = \frac{2\cdot (12\,cm)^{2}\cdot (24\,cm)}{(6\,cm)^{3}}[/tex]

[tex]n = 32[/tex]

32 solid balls are formed.

Adrian is going to invest $9,900 and leave it in an account for 10 years. Assuming the interest is compounded continuously, what interest rate, to the nearest hundredth of a percent, would be required in order for Adrian to end up with $17,700?

Answers

Answer:

did you ever get the answer bc I am struggling on this, pls help.

Step-by-step explanation:

Answer: 5.81%

Step-by-step explanation: Delta Math

A = 17700. P = 9900. t = 10

17700 = 9900e^r(10)

17700/9900 = 9900e^10r/9900

1.7878788 = e^10r

In(1.7878788) = In(e^10r)

In(1.7878788) = 10r

In(1.7878788)/10 = 10r/10

0.058103 = r

5.8103% = r

r = 5.81%

find the length of the arc intercepted by a central angle of 1.5 radians in a circle of radius 9 cm.

Answers

Answer:

13.5 cm

Step-by-step explanation:

The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), and the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:

L/θ = C/2π (C = Circumference = 2πr)

L/θ = 2πr/2π,

L/θ = r,

L = r*θ = 9 cm * 1.5 = 13.5 cm

What is dilation?

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

The scale factor is given as,

SF = 14 / 7

SF = 2

Then the value of the variable 'x' is calculated as,

x = 8 / SF

x = 8 / 2

x = 4 cm

The scale factor is 2. Then the value of the variable 'x' is 1 cm.

(N divided by 10) + 6 = 10. What is the value of N​

Answers

Answer:

[tex]N=40[/tex]

Step-by-step explanation:

1) Remove parentheses.

[tex]\frac{n}{10} +6=10[/tex]

2) Subtract 6 from both sides.

[tex]\frac{n}{10} = 10-6[/tex]

3) Simplify 10-6 to 4.

[tex]\frac{n}{10} = 4[/tex]

4) Multiply both sides by 10.

[tex]n=4 times 10[/tex]

5) Simplify 4 times 10 to 40.

[tex]x=40[/tex]

Therefor, the answer is x=40.

Answer:

N = 40

n / 10 + 6 = 10

n / 10 - 6 = - 6

n / 10 = 4

n x 10 = 4 x 10

n = 40
