Answer:

240/(v+40) + 1 > 240/v

Step-by-step explanation:

Both parties traveled a distance of 240 km.

Simpsons took off at average speed of 40 km/h & 1 hour later: 240/(v+40) + 1

Jacksons took off at average speed of v km/h:  240/v

An inequality in terms of v that models the situation is; [240/(v + 40)] + 1 > 240/v

We are told that distance travelled by both Jackson and Simpson is 240 km each.

Jacksons took off at average speed of v km/h. Thus, their time taken is 240/v

The Simpsons took off at an average speed of 40 km/h faster than Jacksons Speed. Since their start was delayed by an hour, then;

Time taken = [240/(v + 40)] + 1

Thus, the inequality that models the situation is; [240/(v + 40)] + 1> 240/v

Answer:

/12 = 24: d = 288 songs downloaded.

Hope this helps. :)

The equation that represents the given situation is x/12 = 24 and the number of songs downloaded by Oliver is 288.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the instructions given in the question,

Assume that the number of songs downloaded by Oliver in a year is x.

Then, it is divided by 12 and equal to 24.

So, the equation will be,

x/12 = 24

And, the number of songs downloaded by him will be,

x = 24 × 12

x = 288 songs.

Step-by-step explanation:

Answer:

Airplane goes 550 mph

Bike goes 9 mph

Ship goes 27 mph

Step-by-step explanation:

The airplane goes 1,925 every 3.5 hours

Divide 1925 by 3.5

1925/3.5 = 550mph

Do the same thing with the bike’s numbers:

45/5 = 9

So 9mph

And again with the ship:

432/16 = 27

It also says its three times as fast as the bike so:

9 x 3 = 27

So the ship goes 27 mph

Answer:

3/35, 12/35, 16/35, 4/35

Step-by-step explanation:

The box has a total of 35 squares.

The pink fills 3 squares so the pink section is: 3/35

The dark blue section covers 12 squares

So 12/35 is another fraction.

The light blue area covers 16 squares so another fraction is 16/35

The white covers 4 squares

So the last possible fraction is 4/35.

Answer:

$2091 (exact answer is $2090.80)

Step-by-step explanation:

2050 × 6.8% = 6.8

So, interest will add an extra $6.80 to his account

6.8 × 6 = 40.8

So, after 6 years, interest will make him an additional $40.80.

Add 40.80 to his original amount of money.

2050 + 40.8 = 2090.80

Round it up to the nearest dollar.

$2091

The correct answer is B Fitteen is less than r

To translate that into a numerical inaquiltiy, that is 15<r but the answer to the question is B.

Hope this helps!

Brainliest would be nice!

Answer:

B

Step-by-step explanation:

Hello There!

An inequality must include < or > which means greater than or less than

This meaning that the inequality when shown by using words must include the is less than or more (sometimes greater) than

The answer would be B because it uses the expression is less than which can be represented by the inequality sign <

15 is less than r

exchange the inequality sign with is less than

15 < r

they still have the same meaning and it is written as an inequality

Reasons why its not the other answer choices

For A:

Four times 0.45 plus x

written as an expression:

4(0.45+x)

the expression does not include < or > therefore the statement "Four times 0.45 plus x " cannot be written as an inequality

For C:

Half the product of 4 and s

written as an expression:

[tex]\frac{4s}{2}[/tex]

once again the expression does not include an inequality sign therefore C is not the answer.

For D:

eight times p is 20

written as an expression

8p = 20

Like the other answer choices the expression does not include an inequality sign therefore D is not the correct answer choice

The curve of best fit is an illustration of a quadratic regression

The equation of the curve of best fit is [tex]y = -\frac{17}{18}x^2 + \frac{17}3x + 2[/tex], and the height of the frog after 6 seconds is 2 feet

To determine the equation of the curve of best fit, we make use of a graphing calculator

Using the graphing calculator, we have the following calculation summary

The equation of the curve of best fit is represented as:

[tex]y = ax^2 + bx + c[/tex]

Substitute the values for a, b and c.

So, we have:

[tex]y = -\frac{17}{18}x^2 + \frac{17}3x + 2[/tex]

After 6 seconds, the value of x is 6.

So, we have:

[tex]y = -\frac{17}{18} * 6^2 + \frac{17}3 * 6 + 2[/tex]

Evaluate

[tex]y = 2[/tex]

Hence, the height of the frog after 6 seconds is 2 feet

Minimum value = 45

Hence, the range in the number of pretzels :

68 - 45 = 23

Answer:

22

Subtract the minimum (44) and the maximum (66) the answer to this question is 22

Answer:

5 : 2

Step-by-step explanation:

sum the parts of the ratio, 7 + 2 = 9 parts

Divide the quantity by 9 to find the value of one part of the ratio

45 litres ÷ 9 = 5 litres ← value of 1 part of the ratio , then

7 parts = 7 × 5 = 35 litres

2 parts = 2 × 5 = 10 litres

In 45 litres there is 35 litres of milk and 10 litres of water

Adding 4 litres of water gives

35 : 14 = 5 : 2

Answer:

254.5

Step-by-step explanation:

area of circle = pi (3.142) x 9squared

answer 254.5 or 81 pi

Step-by-step explanation:

To find the composite function, it says

[tex](f \: o \: g)(x)[/tex]

means we put the function g(x) into f(x) so that means it looks like

[tex]( \sqrt{x}) {}^{2} - 4[/tex]

Which equal

[tex]x - 4[/tex]

So that expression above is the answer.

To find the range we must find the range of the inner function ,(g(x) and then see which parts it corresponds of f(x).

The range of a g(x) which is a radical function is all real numbers.

The range of a f(x) which is a quadratic function is all real numbers greater than or equal to -4.

This means for our function to work we can use any numbers as long as it greater than -4.

So we would represent that as x is all real numbers as long as x is greater than or equal to -4

In interval notation this would be

[-4,+ infintiy)
