M is directly proportional to r squared when r=2, m=14
Workout the value of r when M =224

Answers

Answer:

r = 8

Step-by-step explanation:

Given that M is directly proportional to r² then the equation relating them is

M = kr² ← k is the constant of proportionality

To find k use the condition when r = 2 , M = 14

k = [tex]\frac{m}{r^{2} }[/tex] =[tex]\frac{14}{4}[/tex]  = [tex]\frac{7}{2}[/tex]

M = r² ← equation of proportion

When M = 224, then

224 =[tex]\frac{7}{2}[/tex]r² ← multiply both sides by 2

7r² = 448 ( divide both sides by 7 )

r² = 64 ( take the square root of both sides )

r = [tex]\sqrt{64}[/tex] = 8

Answer:

157 cm³

Step-by-step explanation:

Given

Radius (r) = 5 cm

height (h) = 6 cm

Volume of the cone (V) = ?

We have the formula

V = 1/3 *π*r²*h

V = 1/ 3 * 3.14 * 5² * 6

b) 2297 cm^3
c) 2179 cm^3
d) 2117 cm^3

plz answer...if you answer with explanation i will surely follow you and rate 5 ​

Answers

Answer:

Option A (2197 cm³)

Step-by-step explanation:

For a cube with length of each side "a" , it's

Total Surface Area = 6a² Volume = a³

_____________________________________________

According to the question ,

Total Surface Area = 1014 cm²

Let the length of each side of cube be 'a'.

Using the formula ,

[tex]6a^{2} =1014[/tex]

[tex]=> a^{2} =\frac{1014}{6} = 169[/tex]

[tex]=> a = \sqrt{169} = +13 \: or -13[/tex]

But length can't be negative . So , length of each side = 13 cm

∴ Volume of cube = 13³ = 2197 cm³

btw, plz brainliestt :))

The value of t is 14

Given the algebraic equation:

[tex]42 + 5t = 8t\\[/tex]

To find the value of t in the algebraic equation given, we would apply the some of the laws of equalities or properties as follows:

[tex]42 + 5t - 5t = 8t - 5t[/tex] (subtraction property of equality)

[tex]42 = 3t\\\frac{42}{3} = \frac{3t}{3}[/tex] (division property of equality)

[tex]14 = t[/tex]

[tex]t = 14[/tex]

Therefore, the value of t is 14.

Determine whether the variable is qualitative or quantitative. Explain your reasoning. The price of a new computer.

Answers

Answer:

The price of a new computer is quantitative.

Step-by-step explanation:

A variable can be classified as qualitative or quantitative.

Qualitative:

When the possible values of the variables are labels, for example, good or bad, yes or no,...

Quantitative:

When the possible values of the variables are numbers, for example 1, 2, 1000,....

In this question:

The price of a computer is a numeric value, so it is a quantitative variable.

"The price of a new computer" is a quantitative variable, because it can be measured and the values are numerical.

What are Qualitative and Quantitative Variables?Quantitative variables are variables whose values are numerical or measured. Example of a quantitative variable is number of students in a given class.Qualitative variables do not have numerical value or are not measurement variables. An example of a qualitative variable is eye color.

Therefore, "the price of a new computer" is a quantitative variable, because it can be measured and the values are numerical.

See
The picture please help test

Answers

Answer:

100.3 sqr. units

Step-by-step explanation:

Area of the composite figure = area of parallelogram + area of 2 semicircles

✔️Area of parallelogram = base * height

Base = 10

Height = 5

Area of parallelogram = 10*5 = 50 sqr. units

✔️Area of 2 semicircles = 2(½*πr²)

radius (r) = ½*8 = 4

Area of two semicircles = 2(½*π*4²)

Area of two semicircles = π*16 = 50.3 sqr.

✔️Area of composite figure = 50 + 50.3 = 100.3 sqr. units

For exponential growth,
the equation is given as,
a = A (1 + 0.01)ˣ
For a = 2A, time x is to be determined,

8. A haircut is $120, how much is a 15% tip? *


Answers

Answer:

18

Step-by-step explanation: 120 times 0.15

Answer:

$18

Step-by-step explanation:

To work out 15% using a calculator:

0.15 multiplied by 120 which is 18

To work out 15% without a calculator:

10% of 120 is 12. (Just remove the last number whenever you want to get 10% or add it on as a decimal if it's greater than 0. e.g. 10% of 40 is 4 but 10% of 48 is 4.8)

To add the 5% divide 12 by 2 which is 6.

Add the 10% to the 5% to get the 15%.

12+6=18

A circle is centered at the vertex of an angle, and the angle's rays subtend an arc that is 74.46 cm long. 1/360th of the circumference of the circle is 0.51 cm long. What is the measure of this angle in degrees?
 ________degrees

Answers

Answer:

146°

Step-by-step explanation:

You're given an angle, where the vertex is the center of a circle. This makes the angle's rays two radii of the circle. You are then given the length of 1/360th of the circle, which is .51cm, which is also 1 degree of the circle.

If the arc of the circle between the angle's rays is 74.46 cm. It becomes a division problem:

[tex]\frac{74.46 cm}{.51 cm}[/tex]

After the division, the fraction simplifies to 146, which is 146 segments of .51cm in the arc, and since .51cm is equivalent to 1 degree of the circle, the arc is 146 degrees.
