Step-by-step explanation:

\(\frac{a^{\frac{1}{3} } }{a^{\frac{1}{4} } }\)  =  \(a^{\frac{1}{3}-\frac{1}{4} }\)  =  \(a^{\frac{1}{12} }\)

Answer:

Step-by-step explanation:

Recall that in the problem x÷y=z

x

÷

y

=

z

, also written

yzx

y z

x

x

x

is called the dividend , y

y

is the divisor , and z

z

is the quotient .

Step 1: Estimate the answer by rounding . You'll use this estimate to check your answer later.

Step 2: If the divisor is not a whole number, then move the decimal place n

n

places to the right to make it a whole number. Then move the decimal place in the dividend the same number of places to the right (adding some extra zeros if necessary.)

Step 3: Divide as usual. If the divisor doesn't go in evenly, add zeros to the right of the dividend and keep dividing until you get a 0

0

remainder, or until a repeating pattern shows up.

Step 4: Put the decimal point in the quotient directly above where the decimal point now is in the dividend.

Step 5: Check your answer against your estimate to see if it's reasonable.

Example:

Divide.

0.45÷3.6

0.45

÷

3.6

Step 1: Since the divisor is greater than the dividend, we will get an answer less than 1

1

. Since 0.45

0.45

is about one tenth as big as 3.6

3.6

, we expect an answer close to 0.1

0.1

.

Step 2: The divisor is not a whole number, so move the decimal point one place to the right to make it a whole number. Move the decimal point in the dividend one place to the right also.

364.5

36

4.5

Step 3: Divide normally, adding extra zeros to the right of 4.5

4.5

when you run out.

                 0

We get 0.125

0.125

.

Step 5: Compare with your initial estimate. 0.125

0.125

is close to 0.1

0.1

, so we're good!

Sometimes, it's easier to use mental math to solve a decimal division problem. This is a good strategy when you can see that if you move the decimal points around, you can change the problem into one you've memorized the answer to.

Example:

Divide.

0.42÷70

0.42

÷

70

We know that 42÷7=6

42

÷

7

=

6

.

If the dividend is decreased by a factor of 10

10

, then the quotient will also decrease by a factor of 10

10

.

42÷7=64.2÷7=0.60.42÷7=0.06 42÷7=6 4.2÷7=0.6 0.42÷7=0.06

And if the divisor is increased by a factor of 10

10

, then the quotient will decrease by a factor of 10

10

.

0.42÷70=0.006

0.42

÷

70

=

0.006

So, the answer is 0.006

0.006

x=7

y=8/3

z=16/3

Step-by-step explanation:

The three equations are

x+y+z=15

x+3y=15

y+z=8

you can use substitution for the first and third equation so it would be

x+8=15

x=7

then use sub for the second equation

7+3y=15

3y=8

y=8/3

and you can finish by using sub for the third equation

8/3+z=8

3z=16

z=16/3

Answer: If in 1980 we had N people who were at least 100 years old, then in 2010 we had N*1.66 people who were at least 100 years old.

Step-by-step explanation:

A really simple conditional statement can be written as:

If P, then Q

Where P is the hypothesis, and Q is the conclusion.

In this case, we know that:

"The number of people with age equal or larger than 100 years old, grew about 66% from 1980 to 2010"

This means that if in 1980 we had N people in that age range, in 2010 we have N*(166%/100%) = N*1.66

Then we can write a conditional statement:

If in 1980 we had N people who were at least 100 years old, then in 2010 we had N*1.66 people who were at least 100 years old.

Answer:

m<BA = 180degrees

Step-by-step explanation:

First you must know that measure of <BA is 180 degrees and m<CD = m<BA

Since <CD = 16z - 12, hence;

180 = 16z - 12

16z = 180++12

16z = 192

z = 192/16

z = 12

Get <BA

m<BA = 16z - 12

m<BA = 16(12) - 12

m<BA = 192 - 12

m<BA = 180degrees

Answer:

22.02

Step-by-step explanation:

Based on the information, both ∧ (conjunction) and ∨ (disjunction) satisfy the commutative property.

It should be noted that to prove the commutativity of the logical connectives ∧ (conjunction) and ∨ (disjunction), we need to show that they satisfy the commutative property

From the truth table, both P ∧ Q and Q ∧ P have the same truth values for all combinations of truth values of P and Q. Therefore, we can conclude that P ∧ Q ≡ Q ∧ P, and ∧ (conjunction) is commutative.

In order to prove P ∨ Q ≡ Q ∨ P, we construct a truth table for both expressions. Both P ∨ Q and Q ∨ P have the same truth values for all combinations of truth values of P and Q. Therefore, we can conclude that P ∨ Q ≡ Q ∨ P, and ∨ (disjunction) is commutative.

Hence, both ∧ (conjunction) and ∨ (disjunction) satisfy the commutative property.

The value of x = \(1\frac{7}{8}\)

Given:  \(\frac{x}{3}\) = \(\frac{5}{8}\)

Solution: To solve for the value of x we have to take all the variables,i.e, x to one side and the rest on the other side,

       \(\frac{x}{3}\) = \(\frac{5}{8}\)

 Taking 3 to the other side, it changes from division to multiplication,

       x = \(\frac{5}{8}\) * 3

       x= \(\frac{15}{8}\)

As it is an improper fraction we need to convert it into a proper or a mixed fraction form,

       x = \(1\frac{7}{8}\)

The first option amongst all the options is the correct one.

Answer:

X= 3

Step-by-step explanation:

To solve this, you must first subtract 2 from 11, to get the 3x isolated.

You'll then have 3x=9, but the x is not alone, so you subtract the 3 from both sides. This leaves you with 3

the value of x will be 3 for the given function 3x+2=11.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given a function  3x+2=11

Simplifying the function:

=> 3x + 2 = 11

subtract by 2

=> 3x +2 - 2 = 11-2

=> 3x = 9

divide by 3 into both sides

=> x = 3

Therefore, the value of x will be 3 for the given function.

The value of q is 0.35.

The value of p is 0.16.

The value of r is 0.27.

The value of P(A given NOT B) is approximately 0.4211.

To calculate the values of p, q, and r, we can use the information provided in the Venn diagram and the probabilities of events A and B.

Given:

P(A) = 0.43

P(B) = 0.62

P(A∩B) = 0.27

Calculating the value of p:

The value of p represents the probability of event A occurring without event B. In the Venn diagram, p corresponds to the region inside A but outside B.

We can calculate p by subtracting the probability of the intersection of A and B from the probability of A:

p = P(A) - P(A∩B)

= 0.43 - 0.27

= 0.16

Therefore, the value of p is 0.16.

Calculating the value of q:

The value of q represents the probability of event B occurring without event A. In the Venn diagram, q corresponds to the region inside B but outside A.

We can calculate q by subtracting the probability of the intersection of A and B from the probability of B:

q = P(B) - P(A∩B)

= 0.62 - 0.27

= 0.35

Therefore, the value of q is 0.35.

Calculating the value of r:

The value of r represents the probability of both event A and event B occurring. In the Venn diagram, r corresponds to the intersection of A and B.

We are given that P(A∩B) = 0.27, so the value of r is 0.27.

Therefore, the value of r is 0.27.

Finding the value of P(A given NOT B):

P(A given NOT B) represents the probability of event A occurring given that event B does not occur. In other words, it represents the probability of A happening when B is not happening.

To calculate this, we need to find the probability of A without B and divide it by the probability of NOT B.

P(A given NOT B) = P(A∩(NOT B)) / P(NOT B)

We can calculate the value of P(A given NOT B) using the provided probabilities:

P(A given NOT B) = P(A) - P(A∩B) / (1 - P(B))

= 0.43 - 0.27 / (1 - 0.62)

= 0.16 / 0.38

≈ 0.4211

Therefore, the value of P(A given NOT B) is approximately 0.4211.

The ratio of the area of the larger circle to the area of the smaller circle will be: 4/1 or 4:1        

Step-by-step explanation:

The diameter of a larger circle = d = 40 cm

                                                 r = d/2 = 40/2 = 20 cm

The area of the larger circle = πr²

                                               = 3.14 (20)²

                                                = 3.14 × 400

                                                 = 1256 cm²

The diameter of a smaller circle = 20 cm

                                                   r = d/2 = 20/2 = 10 cm

The area of the smaller circle = πr²

                                                 = 3.14 (10)²

                                                 = 3.14 × 100

                                                 = 314 cm²

Thus,

The area of the larger circle = 1256 cm²

The area of the smaller circle = 314 cm²

Therefore,

The ratio of the area of the larger circle to the area of the smaller circle will be computed as:

reducing the ration into a simpler form

First add \(\frac{1}{4} and\frac{3}{8}\) canvert 1/4 by multiplying by 2/2 to get a commmon denominator.

\(\frac{1}{4} *\frac{2}{2} =\frac{2}{8}\)

\(\frac{2}{8} +\frac{3}{8} =\frac{5}{8}\)

Now find a common denominator for 3/5 and 5/8 by multiplying 3/5 by 8/8  and 5/8 by 5/5.

\(\frac{3}{5}*\frac{8}{8}=\frac{24}{40}\)

\(\frac{5}{8}*\frac{5}{5}=\frac{25}{40}\)

Now add them.

\(\frac{24}{40}+\frac{25}{40}=\frac{49}{40}=1\frac{9}{40}\)miles

You can also convert all to decimals and add.

3/5 = .6

1/4 = .25
