Answer:

85

Step-by-step explanation:

Because 170 divided by 2.

The number of miles is 75 miles if the vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.

Let x be the total number of miles:

From the question:

y be the total cost of hiring

y = 20 + 2x

y = 170

170 = 20 + 2x

150 = 2x

x = 150/2

x = 75 miles

Thus, the number of miles is 75 miles if the vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.

paraboloid: v = ∫[0,4]πz dz = 8π cone:

v = ∫[0,4]πz^2 dz = 64/3 π

hyperboloid: v = ∫[1,5]π(z^2-1) dz = 112/3 π

Step-by-step explanation:

mother salary: x

father salary:2x

total salary =27000

therefore 3x=27000

so x=900 (divided by 3)

therefore mother salary = 900

father salary=2multiplied by 900=1800

Answer:

Father's monthly salary is P18,000

Mother's monthly salary is P9,000

Step-by-step explanation:

The problem above can be solved by using "algebraic expressions."

Let x be the father's monthly salary

Let y be mother's monthly salary

Formula: x + y = P27,000

If father's monthly salary is twice than what mother makes, then: x = 2y, which means,

2y (father's salary) + y (mother's salary) = P27,000

First step: 2y + y = P27,000

Second step: 3y = P27,000

Third step: y = [tex]\frac{P27,000}{3}[/tex]

Fourth step: y = P9,000

So, mother's salary is P9,000. This means we can get father's salary:

2y = 2 × P9,000 = P18,000 (this is the value of x)

So, father's salary is P18,000.

If we combine both of their salaries, the product is P27,000.

x + y = P27,000

P18,000 + P9,000 = P27,000

So, this explains the answer.

Answer:

-6/5

Step-by-step explanation:

Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.

Answer:

[tex]\displaystyle -1\frac{1}{5}[/tex]

Step-by-step explanation:

[tex]\displaystyle 18x + 15y = 90 \hookrightarrow \frac{15y}{15} = \frac{-18x + 90}{15} \\ \\ \boxed{y = -1\frac{1}{5}x + 6}[/tex]

Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so −1⅕ remains as is.

Step-by-step explanation:

So you subtract the number of peak minutes Katie used last month from the number of peak minutes Katie used this month. Divide the difference by the number of peak minutes Katie used last month. Then multiply by 100 to find the percent increase. Katie used 25% more peak minutes this month than last month.

0.0590222222222222... is a rational number.

We have,

0.0590222222222222.......

We need to determine whether this number is rational or irrational.

A rational number is a number that can be written in p/q form where q≠0.

Some rational numbers are terminating.

Example: 45/2 = 22.5

Some rational numbers are recurring numbers.

Example: 556/3 = 185.33333333333...

The irrational number are those numbers that are non-terminating and non-recurring.

Example: 22/7 = 3.14285714285.....

We have,

0.0590222222222222......

Where 2 is recurring.

So it is a rational number.

Thus 0.0590222222222222... is a rational number.

Answer:

A

Step-by-step explanation:

that means the radius of the left and right circles is 2 units.

and the height of the cylinder is 5 units.

the volume of a cylinder is calculated by first standing it upright on one of the circles, and then the volume is ground area times height.

the area of a circle is pi×r².

so the volume here for us is then

pi×2²×5 units = pi×4×5 = pi×20 = 62.83185307... units

and that makes A the correct answer.

The first term of geometric series is, a = 363/82

An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.

Give that;

Sum of T₃ and T₇ of geometric series = 3267

And, common ratio(r) = 3

Hence, To find first term (a) we can use formula as;

Tₙ = arⁿ⁻¹

Now,  put the value on formula;

T₃ = a(3)³⁻¹

T₃ = (3)²a

And, T₇ = a(3)⁷⁻¹

T₇ = (3)⁶a

Since, T₃ + T₇ = 3267

Hence,

(3)²a + (3)⁶a = 3267

3²(a + 3⁴a) = 3267

(a + 3⁴a) =363

a + 81a = 363

82a = 363

a = 363/82

Thus, The first term of geometric series is, a = 363/82

(y - 9) = 7/4(x + 7)

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope slopes.

The first line is 7x - 4y - 9 = 0.

First let's convert this to y = mx + b form.

Add 4y to both sides.

Divide each term by 4.

The slope is 7/4. A line parallel to this one will also have a slope of 7/4.

The standard point-slope form is:

For the point-slope form, you need two things: a point and a slope.
