Answer:

1/8x + 1/8x

Step-by-step explanation:

We are looking for 1/4x

1/8x + 1/8x = 2/8x which reduces to 1/4x

1/8x + 1/8 Cannot be added as they are not like terms

1/8 + 1/8 = 2/8 which reduces to 1/4 but doesn't have an x

1/2x + 1/2x = 2/2x which reduces to x

Therefore 1/8x + 1/8x is equivalent

∆ABC m∠B = 90° AB = 4 BC = 3<br> Find AC

lutik1710 [3]

Step-by-step explanation:

In ∆ABC, m∠B = 90°

Therefore ∆ABC is a right angled triangle with sides AB = 4 & BC = 3. AC is the hypotenuse.

Hence, by Pythagoras theorem:

$AC^2 = AB^2 +BC^2 \\ \\ \therefore \: AC = \sqrt{AB^2 +BC^2 } \\ = \sqrt{ {4}^{2} + {3}^{2} } \\ = \sqrt{16 + 9} \\ = \sqrt{25} \\ = 5 \\ \\ \huge \red{ \boxed{ \therefore \: AC = 5 \: units}}$

A combination lock has three wheels, each numbered 0-9, and the combination is set at 234. Is the combination a system of indepe

Vika [28.1K]

Answer:

Independent event

Step-by-step explanation:

Independent event is defined as events that will not influence each other. In this question, the combination lock has three separate wheels. Each wheel has one key out of 10 possible numbers. The key of the first wheel will not influence the number pool of second and third wheels. All of the wheels will have 10 possible numbers regardless. Therefore, the combined number is an independent event.

Find Volume for the cones. Round to the nearest TENTH. (A) Radius of 2 in, and a height of 4 inches (B) Diameter of 6 m, and a h

Aleksandr-060686 [28]

Answer:

A. 16.8 in³

B. 28.3 m³

C. 65.4 in³

Step-by-step explanation:

The volume of a cone is given as:

V = ⅓ * pi * r² * h

Where r = radius of base of cone

h = height of cone

A. Radius = 2 inches, height = 4 inches

It's volume is:

V = ⅓ * pi * 2² * 4

V = 16.8 in³

B. Diameter of 6 m, and a height of 3 m

It's diameter is 6 m, therefore, it's radius is:

r = d / 2 = 6 / 2 = 3 m

It's volume is:

V = ⅓ * pi * 3² * 3

V = 28.3 m³

C. Diameter of 5 in, and a height of 10 in

It's diameter is 5 in, therefore, it's radius is:

r = d / 2 = 5 / 2 = 2.5 m

It's volume is:

V = ⅓ * pi * 2.5² * 10

V = 65.4 in³

Two of the cards of an ordinary deck of 52 cards are lost. What is the probability that a random card drawn from this (defective

Nostrana [21]

Answer:

0.72

Step-by-step explanation:

Given :Two of the cards of an ordinary deck of 52 cards are lost.

To Find : What is the probability that a random card drawn from this (defective) deck is a spade?

Solution:

Total number of cards = 52

2 cards are lost

Remaining cards = 50

When no spade card is lost

So, No. of spade cards = 13

Total cards = 50

So, probability of getting spade = $\frac{13}{50}$

When 1 spade card is lost

So, No. of spade cards = 12

Total cards = 50

So, probability of getting spade = $\frac{12}{50}$

When 2 spade cards are lost

So, No. of spade cards = 11

Total cards = 50

So, probability of getting spade = $\frac{11}{50}$

So, The he probability that a random card drawn from this (defective) deck is a spade = $\frac{13}{50}+\frac{12}{50}+\frac{11}{50}$

= $\frac{36}{50}$

= [tex]0.72/tex]

Hence the probability that a random card drawn from this (defective) deck is a spade is 0.72
