The equation 4(3h-4)=2(6h+8) have no solutions.

For the given equation;

4(3h - 4) = 2(6h + 8)

Simplify the equation as;

12h - 16 = 12h + 16

Bring the variable and constant on the different sides;

12h - 12h = 16 + 16

The solution to the given expression when evaluated would be expressed as: 3a + 4b³ - 5 = 3(6) + 4(2³) - 5 = 45.

To evaluate the expression, 3a + 4b³ - 5, when a = 6 and b = 2, substitute the values of a and b into the expression and solve.

Thus, we would have:

3a + 4b³ - 5 = 3(6) + 4(2³) - 5

Solve the exponent

3a + 4b³ - 5 = 3(6) + 4(8) - 5

3a + 4b³ - 5 = 18 + 32 - 5

Add

3a + 4b³ - 5 = 45

Therefore, the solution to the given expression when evaluated would be expressed as: 3a + 4b³ - 5 = 3(6) + 4(2³) - 5 = 45.

Since at 8am Chris goes out on his moped averaging 15mph, the time Chris catches up with Fadi is at 10 am.

Since Fadi set out at 5am on his bike averaging at 6mph, the distance Fadi travels is d = vt where

So, Fadi's distance d = vt

= 6t

Now, At 8am Chris goes out on his moped averaging 15mph, the distance Chris travels is D = v't' where

So, Chris' distance D = v't'

= 15t'

Also, since Fadl sets out at 5 am on his bike and Chris goes out on his moped at 8 am, Chris sets out 8 am - 5 am = 3 hrs later.

So, Chris' time of travel t' = t - 3

So, Chris' distance D = 15t' = 15(t - 3)

Now, Chris will catch up with Fadi when they both cover the same distance

So, d = D

6t = 15(t - 3)

6t = 15t - 45

6t - 15t = -45

-9t = -45

t = -45/-9

t = 5 hours

Since Chris's time is t' = t - 3, substituting t = 5 into the equation, we have

t' = 5 - 3

= 2 hours

So, Chris catches up with Fadi 2 hours later at 8 am + 2 hours = 10 am.

So, the time Chris catches up with Fadi is at 10 am.

The required answer for 1/3 of x is 14 is x = 42.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given equation is,

1/3 of x is 14

Thus converting it into numerical expression.

So we have,

1/3 of x = 1/3 * x= x/3

Thus is equal to 14

Thus, the equation we get is,

x/3 = 14

To solve the above isolate x on one side and other terms to another.

Thus multiplying whole equation by 3 we get,

3*x/3 = 14*3

Simplifying we get,

x = 42

This is the required answer for the given expression.

Thus, the required answer for 1/3 of x is 14 is x = 42.

Solving for B gives B = 2/ F + g³

Subject of formula can be defined as the variable that is expressed in terms of other variables in an equation or expression.

Given the equation;

F(B-g³)=2

To make 'B' the subject of formula, we have to take the following steps

Divide both sides by F, we have;

F(B-g³) / F = 2/ F

we then have;

B - g³ = 2/F

Now, make 'B' the subject of formula by making all the other terms over the equality sign

We have;

B = 2/ F + g³

Thus, solving for B gives B = 2/ F + g³

Answer: a(a^6)^2a^7 = [tex]a^{20}[/tex]

Step-by-step explanation:

Given data,

                 = a(a^6)^2a^7

We can write,

                   = [tex]a * (a^{6}^)^{2} * a^{7}[/tex]

Simplify using exponent power rule,  [tex](a^{n} ) ^{m}[/tex] = [tex]a^{mn}[/tex]

So, we can write using formula,

                           = [tex]a * a^{6*2} * a^{7}[/tex]

                           =  [tex]a * a^{12} * a^{7}[/tex]

Multiply the monomials,

We can use the formula,     [tex]x^{a} * x^{b} * x^{c}[/tex] = [tex]x^{a+b+c}[/tex]

So, we can write,

                            = [tex]a^{1+12+7}[/tex]

                             = [tex]a^{20}[/tex]

We can state that the given relations:

{(3, 2), (-1, 3), (5, 2)} is a function.

{(9, -1), (3, 6), (-2, 4), (3, 0)} is not a function.

A relation is a function if each of the x-values in the relation has exactly one corresponding y-value it is related to.

Given the relation with the ordered pairs, {(3, 2), (-1, 3), (5, 2)}, we can see that each x-value has exactly one y-value.

For the relation, {(9, -1), (3, 6), (-2, 4), (3, 0)}, we can observe that the x-value "3" has three corresponding y-values, "6, and 0", therefore, it is not function.

Therefore, we can state that the given relations:

{(3, 2), (-1, 3), (5, 2)} is a function.

{(9, -1), (3, 6), (-2, 4), (3, 0)} is not a function.

Answer:

7.59*10^1

Step-by-step explanation:

write the number as a decimal - 75.9

make it a new number thats somewhere between 1&10 by moving the decimal place - 7.59

define the power of 10 -10^1

put them all together! - 7.59*10^1

The reason is that the binomial formula is telling us the probability of a particular number of successes. Let’s take 5 turns at bat for a baseball player who gets hits 20% of the time. We want to find the probability that he will get exactly 2 hits. He could get hits on tries 1 & 2, 1&3, 1&4, 1&5, 2&3, 2&4, 2&5, 3&4, 3&5, 4&5. There’s no difference between getting hits on the 1st & 2nd, and getting hits on the 2nd and 1st. They’re the same thing. A permutation would treat those as different, when in reality the order doesn’t matter.

The reason the Binomial Distribution is able to use a combination as oppose to a permutation is because of the symmetry of these types of problems.

Suppose you have n objects of 2 categories. x of them are in the first category and y in the second. Therefore the number of ways you can arrange these n objects is:

Since this also describes the number of ways you can arrange failures and success in a binomial problem, let’s substitute this in place of the combination:

where x = number of repeats in successes and y = number of repeats in failures

Therefore expressing the Binomial Distribution as a combination simplifies the process slightly. However, it’s important to recognize that the combination used is actually a permutation in disguise; it must be a permutation because order matters in the context of Binomial Distributions. The combination doesn’t directly explain the number of ways to arrange the successes and failures, but can be equated to the permutation that does.

Answer:

x=300

Step-by-step explanation:

138=46%x

x=300

hope this helps!

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

46% = 138

100% = 300

The total number of cupcakes sold on that day is 300.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of mocha cupcakes sold in a day = 138

The percentage of mocha cupcakes sold in a day = 46%

The percentage of total cupcakes sold in a day = 100%

Now,

46% = 138

Multiply 100/46.

100/46 x 46% = 100/46 x 138

100% = 300

Thus,

The total number of cupcakes sold on that day is 300.

The lengths of the three sides are 16 feet, 21 feet, and 27 feet

let the shortest side be x

then the second side would be x+ 5 feet

and the third side would be 2x- 5 feet

as we are provided with the parameter of the deck as 64 feet  

Parameter = sum of all sides

64        = x + (x+5) + (2x-5)

64        = 4x

So, in order to find out the measurement of the sides of the triangular deck we need to solve this linear equation  

64        = 4x

X          = 64/4

X          = 16 feet

Therefore, first side/ shortest side = x= 16 feet

Using function concepts, it is found that:

a) Point (3,-13) is not on the graph, because substituting x = 3 on the equation does not result in 13.

b) If x = 1, f(x) = -3, hence point (1,-3) is on the graph of f.

c) if f(x) = 2, x = 16, so point (16,2) is on the graph of f.

d) The domain is all real numbers except x = 4.

e) The x-intercept is of x = -8.

f) The y-intercept is of y = -2.

The function is given by:

f(x) = (x + 8)/(x - 4).

Hence, when x = 3:

f(3) = (3 + 8)/(3 - 4) = 11/-1 = -11.

Hence:

Point (3,-13) is not on the graph, because substituting x = 3 on the equation does not result in 13.

When x = 1, we have that:

f(1) = (1 + 8)/(1 - 4) = 9/-3 = -3.

If x = 1, f(x) = -3, hence point (1,-3) is on the graph of f.

For f(x) = 2, we have that:

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

2x - 8 = x + 8

x = 16.

Hence:

if f(x) = 2, x = 16, so point (16,2) is on the graph of f.

The domain of a function is the set that contains all possible input values of the function.

This function is a fraction, meaning that the denominator cannot be zero, so:

x - 4 = 0 -> x = 4.

Hence:

The domain is all real numbers except x = 4.

For this problem, we have that:

f(x) = 0.

(x + 8)/(x - 4) = 0.

x + 8 = 0

x = -8.

f(0) = 8/-4 = -2.

Hence:

e) The x-intercept is of x = -8.

f) The y-intercept is of y = -2.
