Answer: 6.

Step-by-step explanation:

Since it starts with 2 kilometers in 3 minutes add 3 more minutes that would but six then double the kilometers to 4 then add another 3 minutes which would but 9 where it stops and add another 2 in the kilometers then i would be 6 .

step by step:

1. 3 minutes and 2 km

2. add 3 more (6) and double the kilometers 2 times(4)

3. add 3 more (9) and add another 2 to the km (9)

The length and width of the lot are 46m and 36m  respectively

Let the width of the lot be x,

therefore, length=x+10 (as the lot must be 10m longer than it's wide)

Now, according to the question:

Area of the lot= 1656 m²

Area of a rectangle is given by the product of it's length to width, that is:

⇒ Length × Width= 1656 m²

⇒ (10+x).x= 1656

⇒ 10x+x²= 1656

⇒ x²+10x-1656=0

⇒x²+46x-36x-1656=0

⇒x(x+46)-36(x+46)=0

⇒(x-36)(x+46)=0

⇒x=36 or x=-46(which can be ignored)

∴ x=36 and 10+x=46

So, the length of the lot is 46m and the width is 36m.

For the Δabc the measure of angle c is ∠c = 113°.

What is triangle?

Three edges and three vertices make up a triangle, which is a polygon. It is among the fundamental shapes in geometry. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, any three points that are not collinear determine a singular triangle and a singular plane at the same time.

Consider, the given triangle Δabc with a = 30°, b = 37°.

We have to find the measure of ∠c.

Since the sum of three angles of triangle is 180°.

So,

∠a + ∠b + ∠c = 180°

30° + 37° + ∠c = 180°

67° + ∠c = 180°

∠c = 180° - 67°

∠c = 113°

Hence, for the Δabc the measure of angle c is ∠c = 113°.

The planet that has the larger mass is the planet B and the measurements in standard forms are

From the question, we have the following parameters that can be used in our computation:

Planet A = 5*10^26 kilograms

Planet B = 2*10^28 kilograms

Rewrite the masses properly

So, we have

Planet A = 5*10²⁶ kilograms

Planet B = 2*10²⁸ kilograms

The exponent 28 is greater than the exponent 26

This means that

2*10²⁸ is greater than 5*10²⁶

So, we have

Planet B has the larger mass

When the measurements are expressed in standard forms, we have

Planet A = 500000000000000000000000000 kilograms

Planet B = 20000000000000000000000000000 kilograms

Answer: pls show list of equations

Step-by-step explanation:

In an exhibition, the cost of tickets for an adult is 5 more than thrice the cost o f ticket for a child.  

What is   equation?

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.

Equation relates the cost, y, of adult ticket in terms of the cost, x, of child ticket.

Cost of Adult ticket = y

cost of child ticket  = x

cost of tickets for an adult is 5 more than thrice the cost o f ticket for a child.  

=> cost of tickets for an adult = 5 + 3 (cost o f ticket for a child.)

=> y  = 5 + 3x

=> y = 3x + 5

If the line y=-x+4 is tangent to the graph of f(x) = x^2 - 5x + a, it means that the line and the graph of the function are just touching at a single point, and are not intersecting at any other points.

To find the value of a, we can start by setting the equation for the line and the equation for the function equal to each other:

y = -x + 4

f(x) = x^2 - 5x + a

Then, we can substitute the equation for the function into the equation for the line:

-x + 4 = x^2 - 5x + a

We can then solve this equation for a by moving all the terms to one side:

-x + 4 - x^2 + 5x = a

-x^2 + 6x - 4 = a

We can see that the left-hand side of this equation is a quadratic expression in x, and we know that a quadratic function is tangent to a line when the line is a horizontal tangent. This occurs when the derivative of the function is equal to the slope of the line.

The derivative of f(x) = x^2 - 5x + a is 2x - 5, so we can set this equal to the slope of the line, which is -1:

2x - 5 = -1

2x = -6

x = -3

Now that we know the value of x, we can substitute it back into the equation for the function to find the value of a:

f(-3) = (-3)^2 - 5(-3) + a

f(-3) = 9 + 15 + a

f(-3) = 24 + a

Since the line and the function are just touching at this point, the y-value of the function at x=-3 must be equal to the y-value of the line at x=-3. We can substitute these values into the equation for the line to find the value of a:

y = -(-3) + 4

y = 3 + 4

y = 7

Substituting this back into the equation for the function, we get:

f(-3) = 24 + a = 7

a = 7 - 24

a = -17

Therefore, the value of a is -17.

what do you mean by tangent?

A tangent is a line that touches a curve at a single point, but does not intersect the curve at any other points. In other words, it is a line that is just "skimming" the curve, rather than crossing it.

Let the cost of one apple pie be $x

And cost of one pumpkin pie be $ y.

According to given problem,

For Lisa :  sold 8 apple pies and 4 pumpkin pies for a total of $80

8x + 4y = 80   ------------(1)

Solving equation (1) and (2), to get x and y.

Subtract equation (2) from equation (1)

A product is designed to function for 10,000 hours with a 3% chance of failure , then Average number of failures per hour = 0.03/10000 = 0.000003 and MTTF = 1/0.000003 = 333,333 hours

Given,

Chance Product is designed to function for 10,000 hours

of failure is 3%

To find,

Average number of failures per hour

MTTF

Solution,

Average number of failures per hour = Chance of failure/Total hours of function

= 3%/10000

= 0.03/10000

= 0.000003

MTTF = 1/Average number of failures per hour

= 1/0.000003

These bases often have a circular form (like a circle), and a line segment known as the axis connects the centres of the two bases. The height of the cylinder is "h," while the radius of the cylinder is "r," measuring the distance from the axis to the outside surface.

Each form has specific characteristics that set it apart from other shapes. Consequently, cylinders share those same traits.

Answer:D. y = 3/4x + 1

Answer:The Flemish giant rabbit weighs 32 pounds.

Step-by-step explanation:

Answer:

n = 8

Step-by-step explanation:

interior angle = [tex]\frac{180(n-2)}{n}[/tex]

given that interior angle = 135° then equating gives

[tex]\frac{180(n-2)}{n}[/tex] = 135 ( multiply both sides by n to clear the fraction )

180(n - 2) = 135n ← distribute parenthesis on left side

180n - 360 = 135n ( subtract 135n from both sides )

45n - 360 = 0 ( add 360 to both sides )

45n = 360 ( divide both sides by 45 )

n = 8

Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.

Parallel lines will have the same slope but different y-intercepts  so again we can  use the coordinates to determine the y intercept of the new equation.

So we know that the slope intercept formula is y=mx + b where m is the slope and b is the y-intercept so we will input the x and y coordinates to solve for b.
