Answer:

x = 7 √3 km

Step-by-step explanation:

Here, we want to get the value of x

As we can see, we have a right angled triangle with hypotenuse 14 km

we can use the Pythagoras’ theorem to get the value of x

Mathematically, the square of the hypotenuse equals the sum of the squares of the two other sides

Thus,

14^2 = x^2 + 7^2

x^2 = 196-49

x^2 = 147

x = 7 √3 km

Answer: 15 ft 9 in

Step-by-step explanation:

The division of fraction 9/14 by 15/2 in simplest form is 3/70 by dividing both the numerator and the denominator by the GCD

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 15/2 is 2/15. Therefore, we can rewrite the division as multiplication:

(9/14) * (2/15)

Next, we can multiply the numerators together and the denominators together:

(9 * 2) / (14 * 15)

Simplifying further, we get:

18 / 210

To simplify the fraction, we can find the greatest common divisor (GCD) of the numerator and the denominator, which is 6 in this case. Dividing both the numerator and the denominator by the GCD, we get:

18 ÷ 6 / 210 ÷ 6

This simplifies to:

3 / 35

Therefore, the division of 9/14 by 15/2 in simplest form is 3/70.

In summary, to divide fractions, we multiply the first fraction by the reciprocal of the second fraction. Then, we simplify the resulting fraction by finding the GCD of the numerator and the denominator and dividing both by the GCD. Applying these steps to the given fractions, we obtain the simplified form of 3/70.

Answer:

We must add 400 ml of water.

Step-by-step explanation:

We can use the following equation:

[tex]C_{i}V_{i}=C_{f}V_{f}[/tex]

Where:

Now, we just need to solve the equation for V(f).

[tex]V_{f}=\frac{C_{i}V_{i}}{C_{f}}[/tex]

[tex]V_{f}=\frac{80*150}{30}[/tex]

Answer:

8.30

Step-by-step explanation:

Lee mailed 3 packages

If he paid 1.70 for 1 package and 3.60 for 2 package

= 3.60×2 + 1.70

= 7.2+1.70

= 8.9

If Lee paid 3.60 for 1 package and 1.70 for 2 packages

= 3.60 + 1.70(2)

= 3.60 + 3.4

= 7

Hence the price paid to mail the thee packages is 8.30 because it falls in between 7 and 8.9

Answer: a. $8.30

Step-by-step explanation:

Highest paid was $3.60 and lowest paid was $1.70. There is a middle package that cost less than $3.60 and more than $1.70.

= 3.6 + 1.7

= $5.30

This rules out option c because we have not added the price of the third package and it is already higher than option c.

Add the maximum twice:

= 3.6 + 3.6 + 1.7

= $8.90

If the second package was assumed to have the same cost as the highest paid, the total would still be less than options b and d which makes them both wrong.

Option a is the most feasible answer.

Answer:

All polynomial functions of positive, odd order have at least one zero (this follows from the fundamental theorem of algebra), while polynomial functions of positive, even order may not have a zero (for example x4+1 x 4 + 1 has no real zero, although it does have complex ones).

Step-by-step explanation:

Answer:

Original Equation: s + 3 1/2 = 8 1/2

Subtract 3/12 from both sides: s + 3 1/2 - 3 1/2 = 8 1/2 - 3 1/2

Simplify: s = 5

Answer:

x = 24 , y = 10, z = 17

Step-by-step explanation:

Given

6x - 29 = 115

6x = 115 + 29

6x = 144

x = 144 / 6

x = 24

3y - 1 = 29

3y = 29 + 1

3y = 30

y = 30 / 3

y = 10

4z - 32 = 36

4z = 36 + 32

4z = 68

z = 68 / 4

z = 17

Point of intersection of equations is (1 , 6)

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.

Given equations

y = 3x + 3    ---------(1)

y = x + 5      ---------(2)

Subtracting equation 2 from equation 1.

y - y = 3x + 3 - (x + 5)

0 = 3x + 3 - x - 5

0 = 2x - 2

x = 1

Putting value of x in equation 2

y = 1 + 5

y = 6

Intersection point,

(x , y) = (1 , 6)

Hence, (1 , 6) is the point of intersection of given equations.

Answer:

w = 2 + 8x

Step-by-step explanation:

this is the only equation where, after plugging in hours and wages, the values are correct

The equation where, after plugging in hours and wages, the values are correct would be; w = 2 + 8x

An equation is an expression that shows the relationship between two or more numbers and variables.

We have been given that John delivers newspapers every morning in his neighborhood.

John gets paid based on the number of hours x, that he works.

Thus the only equation where, after plugging in hours and wages, the values are correct would be;

w = 2 + 8x

Substituting x = 1

w = 2 + 8(1)

w = 10

Hence, this equation is correct.

You have painted more.

Step-by-step explanation:

Marcos should paint 5/9 of the deck of a sailboat.

At the end of the day he painted 21/36.

Reducing this to the simplest form = 21/36

Dividing Numerator and Denominator by 3

= 7/12

Finding the difference between both fractions

= 7/12 - 5/9

The Lowest Common Denominator = 36

= 21 - 20/36
