Answer:

SA = r (PI)   + r (PI) 2

Step-by-step explanation:

The surface area of the solid figure would be; SA = πrl + πr²

The total surface area of a cone is given by:

The Surface area of the cone =[tex]\pi r(r+\sqrt{h^2+r^2} )[/tex]

where r is the radius of the cone, h is the height of the cone, l is the length of the cone

Since it is known that Right circular cone is the cone in which the line joining peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.

Length = [tex]\sqrt{h^2+r^2}[/tex]

Therefore, we can conclude that;

The total surface area of the cone is given by the following formula;

SA = πrl + πr²

Answer:

HCF = 14

LCM = 1680

Step-by-step explanation:

Factorizing the given values

210 = 2 * 3 * 5 * 7

112 = 2 * 2 * 2 * 2 * 7

Since 2 * 7 is common to both factors

Hence the HCF = 2 * 7 = 14

For LCM, we we will multiply all the prime factors that are in both

LCM = 2* 2 * 2 * 2 * 3 * 5 * 7

LCM = 112 * 15

LCM = 1680

Hence the LCM is 1680

Answer:

240 minutes or 4 hours

Step-by-step explanation:

So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes.

If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.

Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.

So you have 45/80 and 45/120.

Now add both fractions by finding the lowest common denominator which is 240.

135/240 + 90/240 = 225/240

So Mack did the remaining 15/240.

Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.

Then multiply

15 x 16 = 240

so it would take him 240 minutes or 2 hours.

Step-by-step explanation:

Answer:

x = 0 and y = 4.

Step-by-step explanation:

The given equations are :

4x+2y=8 ...(1)

x+y=4 ...(2)

Multiply equation (2) by 2.

2x+2y=8 ...(3)

Subtract equation (3) from (1).

4x+2y-(2x+2y)=8-8

4x+2y-2x-2y=0

2x = 0

x = 0

Put the value of x in equation (2).

0+y=4

y = 4

So, the value of x and y are 0 and 4.

Step-by-step explanation:

[tex]\begin{cases} -3x -3\:\: for\:\: x<-2\\\\6x -28\: \: for\:\: x\geq 5  \end{cases}[/tex]

f(5) will fall in the interval x≥5 and its corresponding function is:

∴ f(5)= 6*5 - 28 = 30 - 28 = 2

Answer:

15 (3rd option)

Step-by-step explanation:

Circumference formula=2 x pi x r(radius)

So, 30 pi = 2 pi r

Next, isolate the r(radius)

30 pi / 2 pi = r

The 2 pi's cancel out and leaves 30/2

r=15

Answer:

a baby weight more because the baby will grow and will weight more then a puppy

Step-by-step explanation:

Answer:

A puppy that weights 8.5 kilograms weighs more.

Step-by-step explanation:

A puppy that weights 8.5 kilograms weighs more. Why? Well if you convert the 11 pounds from the baby to kilograms it would equal about 5 kilograms. The puppy's weight in kilograms is 8.5 and its weight in pounds is 18.7, while the baby's weight in kilograms is 5 and it's weight in pounds is 11.

Puppy's Weight Kilograms: 8.5

Puppy's Weight Pounds 18.7

Baby's Weight Kilograms: 5

Baby's Weight Pounds: 11

Weight in Kilograms: Puppy: 8.5 > Baby: 5

Weight in Pounds: Puppy: 18.7 > Baby: 11

Therefore, the puppy is heavier.

Answer:

y = 1.5

Step-by-step explanation:

Given y is inversely proportional to [tex]\sqrt{1+x}[/tex] , then the equation relating them is

y = [tex]\frac{k}{\sqrt{1+x} }[/tex] ← k is the constant of variation

To find k use the condition when x = 8, y = 2 , then

2 = [tex]\frac{k}{\sqrt{1+8} }[/tex] = [tex]\frac{k}{\sqrt{9} }[/tex] = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )

6 = k

y = [tex]\frac{6}{\sqrt{1+x} }[/tex] ← equation of variation

When x = 15, then

y = [tex]\frac{6}{\sqrt{1+15} }[/tex] = [tex]\frac{6}{\sqrt{16} }[/tex] = [tex]\frac{6}{4}[/tex] = 1.5

Step-by-step explanation:

a² + b² =² c²               the Pythagorean theorem

RQ² + RS² = QS²            Solve RS

6² + RS² = 8²

RS² = 64 -36

RS² = 28

RS = √28                  28 is slightly > 25   and since  √25 =5

RS = 5.3                    actually 5.2915  to a few more significant digits

Step-by-step explanation:

use tangent formula

[tex] \tan(40) = \frac{h}{75} [/tex]

Answer:

h ≈ 62.9 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{75}[/tex] ( multiply both sides by 75 )

75 × tan40° = h , then

h ≈ 62.9 ft ( to 1 dec. place )

The answer is -12
