Kevin is tiling his bathroom. The floor is 6-by-5 feet, minus a 2-by-2.5-feet vanity. The tiles he likes are 1-by-1 foot. If he plans to buy 10 percent extra for waste, how many tiles will he need?

Answer: Choice A

Arithmetic, common difference = -10

==========================================

Explanation:

We subtract 10 from each term to get the next one

5-10 = -5

-5-10 = -15

-15-10 = -25

This is the same as adding -10 to each term

5+(-10) = -5

-5+(-10) = -15

-15+(-10) = -25

So this is why the common difference is -10 and the sequence is arithmetic.

Answer:

The graph of the system of equations solves the equation  [tex]\frac{1}{2}[/tex] x - 4 = -2x + 1 ⇒ D

Step-by-step explanation:

Let us revise some important notes about the slope and y-intercept of a line

The form of the linear equation is y = m x + b, where m is the slope and b is the y-intercept

The y-intercept (0, b) is the the point of intersection between the line and the y-axis

To solve our question without any calculation, let us find the direction of the slopes and their y-intercepts

∵ The direction of the blue line is to the left

→ That means m in the equation is negative

∴ Its slope is negative

∵ The line intersects the y-axis at point (0, 1)

→ That means b in the equation = 1

∴ The number in the equation is 2

→ Look at the answer we have only one answers have negative slope and

   y-intercept = 1 in the right hand side ⇒ D

∴ The equation of the blue line is represented by the left side -2x + 1

→ That means the equation of the red line is represented by the left side

∵ The direction of the red line is to the right

→ That means m in the equation is positive

∴ Its slope is positive

∵ The line intersects the y-axis at point (0, -4)

→ That means b in the equation = -4

∴ The number in the equation is -4

→ Only D has a positive slope and y-intercept = -4 in the left side

∴ The equation of the red line is represented by [tex]\frac{1}{2}[/tex] x - 4

The graph of the system of equations solves the equation  [tex]\frac{1}{2}[/tex] x - 4 = -2x + 1

Another way:

You can solve each equation to find the value of x, then substitute it in one side of the equation to find y , the values of x and y must be (2, -3) as the point of intersection of the two lines in the graph

Answer: 17.5

Step-by-step explanation:

7:10 = x:25

times both sides by 25

25(7/10) =x

than solve for x

X = 25 × (7/10)

X = 17.5

Answer:

Step-by-step explanation:

let the distance of the trail be x

and let the time be t

given that franks average speed is 2 miles per hour

the distance covered by Frank is x-3

the time taken by Frank to cover the distance is

we know that speed=distance/time

2=x-3/t

2t=x-3  

x=2t+3---------1

Jasmine speed= 4 miles per hour

speed=distance/time

4=x/t

x=4t--------2

equating 1 and 2 above we have

2t+3=4t

solving for t we have

4t-2t=3

2t=3

t=3/2

t=1.5

That is 1hr 30 min

Answer:

The value of f(1) is greater than value of f(3)

Step-by-step explanation:

We substitute..x = 1..into the given equation....where we say...

; -2(1)^2 + 3(1) + 10 = 11

Then we substitute..x = 3..into the given equation

;-2(3)^2 + 3(3) + 10

;-2(9) + 9 + 10 = 1

If f(1) = 11 and f(3) = 1...then the value of f(1) is greater than the value of f(3)

Step-by-step explanation:

The given function is f(x) = -2x² + 3x + 10. We are asked to find f(1) and f(3).To find f(1), we substitute 1 in the place of x in the given function and evaluate it.

That is,f(1) = -2(1)² + 3(1) + 10= -2 + 3 + 10= 11To find f(3), we substitute 3 in the place of x in the given function and evaluate it.
That is,f(3) = -2(3)² + 3(3) + 10= -18 + 9 + 10= 1We see that f(1) is larger than f(3).

Hence, the correct answer is "The value of f(1) is larger than the value of f(3)."

Answer:

1. plane parallel- ABC

2. segment parallel- DA

3. segment parallel- DE

4. segmney skew- FC

The required answers are,

1. A plane parallel to plane DEF is ABC.

2. A segment parallel to FC is AD.

3. A segment parallel to AB is DE.

4. A segment skew to DE is FC.

A segment is a set of points consisting of two points of the line called the endpoints, and all of the points of the line between the endpoints.

In mathematics, a plane is a flat, two-dimensional surface that extends indefinitely.

Now from the given figure following information can be extracted-

Plane of DEF is parallel to plane ABC,

Segment FC is parallel to segment AD,

Segment AB is parallel to segment DE,

Segment DE is skew to segment FC.

Thus, the required answers are,

1. A plane parallel to plane DEF is ABC.

2. A segment parallel to FC is AD.

3. A segment parallel to AB is DE.

4. A segment skew to DE is FC.

Answer:

583 miles

Step-by-step explanation:

Let's draw this out (see attachment).

The straight line path creates the hypotenuse of a right triangle with legs of lengths 300 and 500. So, we use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:

a² + b² = c²

Here, a = 300 and b = 500. Then:

300² + 500² = c²

90000 + 250000 = c²

340000 = c²

c = √340000 ≈ 583.1 ≈ 583 mi

Thus, the answer is 583 miles.

Answer:

see explanation

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

Here C = 32π , thus

πd = 32π ( divide both sides by π )

d = 32

Thus a coin with diameter 32 mm should fit through a slot of 35 mm

b= 2 [tex]\frac{A}{Hb}\\[/tex] =   2 · [tex]\frac{12}{8}[/tex] = 3

Answer:

base= 3

Step-by-step explanation:

You need to work backwards to solve this problem

A= 1/2bh

with the information given, the equation should look like this:

12= 1/2b8

To get rid of the fraction, you flip it, and you multiply both sides by that (1/2 fliped is 2)

so  2* 12= 1/2b8 *2

-----------------------------------------------------------------------------

** You can see that the 1/2 and the two cancel each other out. This is why:

1/2* 2/1= 2/2

2/2=1

1 * b8 is just b8

----------------------------------------------------------------------------

So now you have:

24= b8

you want to get b by itself, so you use inverse operations ( you divide both sides by 8)

24/8= b8/8

your final answer is 3=b

you can plug in 3 into the original equation to check your answer!!!
