Find the missing number to make the fractions equivalent. 3/4 = 9/?

The cost for 1 liter of premium gasoline is $0.43 greater than the regular gasoline.

This is referred to as the total amount of money and resources which are used by companies in other to produce a good or service.

In this scenario, we were given 25 liters of regular gasoline for $58.98 or 25 liters of premium gasoline for $69.73.

Cost per litre of premium gasoline is = $69.73 / 25 = $2.79.

Cost per litre of regular gasoline is = $58.98/ 25 = $2.36.

The difference is however $2.79 - $2.36 = $0.43.

Therefore the cost for 1 liter of premimum gasoline is $0.43 greater than the regular gasoline.

In interval notation, the answer is:

The solution on the number line is:

Given:

Constructing a parallel line to line AB and passing through point P.

To find:

The error occurred in the construction.

Explanation:

The procedure is,

The first arc must be drawn centred at C.

The second must be drawn centred at P.

Finally, the third arc must be drawn centred at F.

But here, the third arc is drawn centred at D. This is wrong.

Therefore, the correct step is that the third arc must be centred at F.

Final answer:

The third arc should be drawn centred at F.

By definition, Scientific notation has the following form:

Where the coefficient "a" is a number from 1 to 10 (but not including 10), and the exponent "n" is an Integer.

In Scientific notation, the Decimal point must be after the first digit of the coefficient.

In this case, you have this number:

Notice that, in order to write it in Scientific notation, you must move the decimal point one place to the left. Therefore, the exponent of the base 10 will be 1:

The answer is:

Here the values are proportional to each other.

Proportionality ratio is,

Then scale on X-axis representing weight in Newton is 1 unit is equal to 7 Newton

And on the the Y axis representing distance in cm is 1 unit is equal to 5 cm.

We have to translate the expression "The product of v and the difference of c and 10".

We know that the expression is a product of two factors: v and a difference. The difference is between the terms c and 10, so it can be written as (c-10).

Then, the product can be written as:

Answer: the expression is v*(c-10)

Answer

The equation for this question is

84 + 10x = 219

The number of minutes it'll take the submarine to reach 219 feet is 13.5 minutes

Explanation

Let the number of minutes it will take the submarine to reach 219 feet below the surface be x minutes.

The number of feet the submarine reaches in x minutes = (10x) feet

Since the submarine started from 84 feet, in x minutes, it would have reached a depth of

(84 + 10x) feet

This is equal to 219 feet

84 + 10x = 219

Subtract 84 from both sides

84 + 10x - 84 = 219 - 84

10x = 135

Divide both sides by 10

(10x/10) = (135/10)

x = 13.5 minutes

Last equation:

Hence, the last equation is the solution.

A cosine function has the form.

Where A refers to the changes of the y-coordinate along the curve, that is, the amplitude. And B refers to the period, that is, the repetition period of the curve.

According to the graph, the amplitude is 1, so A = 1.

Answer

The sum of the sequence = -30072

Explanation

We are given a sequence of numbers and asked to find the sum of the terms up until the last term given. The sequence given is

9, 4, -1,.............., -546

On careful observation of this sequence, we can see that it is an arithmetic progression with a common difference of -5 between consecutive terms.

Common difference = (n + 1)th term - nth term

= 4 - 9 Or -1 - 4

= -5

For an arithmetic progression, the formula for the last term is given as

Last term = a + (n - 1)d

where

L = last term = -546

a = first term = 9

n = number of terms in the sequence = ?

d = common difference = -5

So, we can solve for the number of terms

-546 = 9 + (n - 1)(-5)

-546 = 9 - 5n + 5

-546 = 14 - 5n

14 - 5n = -546

-5n = -546 - 14

-5n = -560

Divide both sides by -5

(-5n/-5) = (-560/-5)

n = 112

We can now use the formula for the sum of an arithmetic progression to find the sum of this sequence.

We know all of these parameters now

Sum of this AP = (112/2) [(2 × 9) + (112 - 1)(-5)]

= 56 [18 + (111 × -5)]

= 56 [18 - 555]

= 56 [ -537]

= -30072

Hope this Helps!!!

The formula for determining the nth term of an arithmetic sequence is expressed as

f(n) = f(1) + (n - 1)d

Where

f(1) represents the first term

d represents the common difference

n represents the number of terms

From the information given,

f(1) = 16

d = 48 - 16 = 80 - 48 = 32

a) The first term of the sequence is 16

b) the common difference is 32

c) The explicit is

f(n) = 16 + 32(n - 1)

d) To find the distance the stone travels in the 5th second, it means that n = 5

Thus

f(5) = 16 + 32(5 - 1)

f(5) = 16 + 32 * 4

f(5) = 144

the distance the stone travels in the 5th second is 144 feet

The parabola that has the height and width similar to the Gateway arc, gives;

(a) The quadratic equation of the parabola is presented as follows;

(b) The completed table is presented as follows;

Width. Height

567. 63.12

478. 225.67

308. 459.2

The shape of a quadratic function is a parabola, which is either upward facing or downward facing

(a) The given dimensions of the arc are;

Height = 625

Width at the base = 598

The points on the parabola are therefore;

(0, 0), (598÷2, 625) = (299, 625), (598, 0)

The equation of the parabola is of the form;

f(x) = a•x² + b•x + c, which gives;

f(0) = 0 = a×0² + b×0 + c = c

c = 0

f(299) = 625 = a×299² + b×299 + 0...(1)

f(598) = 0 = a×598² + b×598...(2

(a×598² + b×598) - 2×(a×299² + b×299) = 0 - 2×625

a•178802 = -2×625

a = -2×625 ÷ 178802

a ≈ -6.991 × 10^(-3)

b ≈ 4.181.

The equation is therefore;

[tex] f(x) = -6.991 \times 10^{-3} \cdot x^2 + 4.181 \cdot [/tex]

(b)

The table of values is completed as follows;

When the width is 567 feet, x = 299 - 567÷2 = 15.5

[tex] \displaystyle{f(15.5) = -6.991 × 10^{-3} \times 15.5² + 4.181 \times 15.5 approx 63.12} [/tex]

When the width is 478 feet, x = 299 - 478÷2 = 60

[tex] \displaystyle{f(60) = -6.991 × 10^{-3} \times 60² + 4.181 \times 60 approx 225.67} [/tex]

When the width is 308 feet, x = 299 - 308÷2 = 145

[tex] \displaystyle{f(145) = -6.991 × 10^{-3} \times 145² + 4.181 \times 145 approx 459.2} [/tex]

The table is therefore presented as follows;

Width. Height

567. 63.12

2) Assuming Jackson does not get any tips or extra money for his job.

The final price of gas per gallon after number of reduction and increment is $12.74.

Given,

The price of gas at store = 4.29 per gallon

The increased amount of gas = 0.55

The new price of gas = 4.29 + 0.55 = 4.84 per gallon

Then decreased 0.25. So, the price of gas = 4.84 - 0.25 = 4.59 per gallon

Again the price increases 8.30 and the new price become, 4.59 + 8.30 = 12.89 per gallon

Then, the price of gas finally went down to .15.

Therefore, the price of gas now is:

12.89 - 0.15 = 12.74

a. 74.99% probability of getting 746 or more peas with red flowers.

b. Since Z < 2, 746 peas with red flowers is not significantly high.

c. Since 746 peas with red flowers is not a significantly high result, we cannot conclude that the scientist's assumption is wrong.

Given,

953 peas in sample with 746 of them having red flower

Scientist's assumption;

Since there is a 3/4 chance that a pea will have a red blossom, we would anticipate 714.75 (or roughly 715) of the peas to do so; hence, the finding of 746 peas with red flowers is higher than we had anticipated.

Here,

Binomial distribution:

Probability of x successes on n trials, with p probability.

Normal distribution:

In a normal distribution with mean μ and standard deviation σ, the z-score of a measure X is given by:

Z = (X - μ) / σ

If  np ≥ 10 and n (1 - p) ≥ 10 , the binomial distribution can be approximated to the normal with:

μ = np

σ = [tex]\sqrt{np(1-p)}[/tex]

Here,

n = 953 and p = 3/4 = 0.75

Lets see,

μ = np = 953 x 0.75 = 714.75

σ = [tex]\sqrt{np(1-p)}[/tex] = [tex]\sqrt{714.75 . (1 - 0.75)}[/tex] = √714.5 = 26.73

a. The probability of getting 746 or more peas with red flowers.

Using continuity correction, this probability is P(X ≥ 746 - 0.5) = P(X ≥ 745.5) , which is 1 subtracted by the p-value of Z when X = 745.5.

Then:

Z = (X - μ) / σ = (745.5 - 714.75) / 26.73 = 30.75 / 26.73 = 1.150

The p value of z score 1.150 is 0.2501

1 -0.2501 = 0.7499

0.7499 = 74.99% probability of getting 746 or more peas with red flowers.

b. Is 746 red-flowering peas noticeably high

Since Z < 2, 746 peas with red flowers is not significantly high.
