Answer:

D

Step-by-step explanation:

D because it is the only choice that obtains things that do not intersect or cross each other at some point. The doors would never cross, unlike the windows or roadways or railways.

So option D would be the best answer.

Step-by-step explanation:

What is the largest of 3 consecutive integers such that the sum of the first and third is equal to three times the second?

3 consecutive angles

= x, x + 1, x + 2

We are told in the question that:

the sum of the first and third is equal to three times the second

a + c = 3b

x + x + 2 = 3(x + 1)

2x + 2 = 3x + 3

3x - 2x = 2 - 3

x = -1

The largest of the three numbers is the third number

= x + 2

x = -1

x + 2 = -1 + 2

The third and largest number is 1

Answer:

answer is I'm guessing B.

Answer: B. 40.84 inches³

Step-by-step explanation:

A can takes the shape of a cylinder. Therefore, the volume of the can will be:

= πr²h

where

π = 3.14

r = diameter/2 = 3.4/2 = 1.7

h = 4.5

Therefore, volume = πr²h

= 3.14 × 1.7² × 4.5

= 3.14 × 2.89 × 4.5

= 40.8357

= 40.84 inches³

Answer:

If [tex]p(x)[/tex] is divisible by [tex]x-2[/tex], then [tex]m = \frac{1}{2}[/tex].

Step-by-step explanation:

Let [tex]p(x) = 2\cdot x^{2}-(m+3)\cdot x - 1[/tex], if [tex]p(x)[/tex] is divisible by [tex]x-2[/tex], then [tex]p(2) = 0[/tex]. That is:

[tex]2\cdot 2^{2}-(m+3)\cdot (2)-1 = 0[/tex]

[tex]8 - 2\cdot m -6 -1 = 0[/tex]

[tex]1 -2\cdot m = 0[/tex]

[tex]2\cdot m = 1[/tex]

[tex]m = \frac{1}{2}[/tex]

If [tex]p(x)[/tex] is divisible by [tex]x-2[/tex], then [tex]m = \frac{1}{2}[/tex].

Answer:

It will be worth about £885.59.

Step-by-step explanation:

The art piece originally costs £600.

And it appreciates at a rate of 3.97% each year.

And we want to find the value of the art after 10 years.

We can write an exponential function to model the situation. The standard exponential function is given by:

[tex]f(t)=a(r)^t[/tex]

Where t is the time in years.

Since it appreciates at a rate of 3.97% each year, the value after each year will be (100% + 3.97%) or 103.97%.

103.97% = 1.0397. So, r = 1.0397:

[tex]f(t)=a(1.0397)^t[/tex]

Our a is the initial value. Therefore:

[tex]f(t)=600(1.0397)^t[/tex]

Then the value of the piece of art after 10 years is:

[tex]f(t)=600(1.0397)^{10}=885.5879...\approx \pounds 885.59[/tex]

It will be worth about £885.59 after 10 years.

Answer:

885.59

Step-by-step explanation:

1. 600 + 23.82

2. 623.82 + 24.77

3. 648.59 +25.75

4. 674.34 + 26.77

5. 701.11 + 27.83

6. 728.94 + 28.94

7. 757.88 + 30.09

8. 787.97 + 31.28

9. 819.25 + 32.52

10. 851.77 + 33.82

After 10 years the art valued for 885.59 British Pounds.

Answer:

2970

Step-by-step explanation:

I hope it helped :) if it didnt just message me since in confused whats the dot between the 6.3 and 10²

Answer:

2.97*10^3

Step-by-step explanation:

You have to solve it first so you have 2970 as your answer but you want it in scientific notation. To do this put the decimal after the first number this gives you 2.970. Whenever you need to make the number bigger you use a positive power and whenever you want to make a number smaller you use a negative power. The amount of powers the 10 gets is the amount of times you move it over. You have 2.970 and to get to the original number you need to move it 3 places to the right. Going to the right with your decimal makes it bigger which what you want, so you have 2.970*10^3 as your answer.

Answer:

-x + 1

Step-by-step explanation:

First, rewrite 2x +3 - 3x + (-2) as 2x +3 - 3x - 2.  Note that +(-2) = -2.

Next, combine like terms.  We get -x + 1.  

Double check to determine whether this is one of the given possible answers.

Answer:

213

Step-by-step explanation:

Use the triangle area formula : [tex]\frac{1}{2}[/tex]×bh

b = length       h = height

b = 14.8 + 5.2      h = 21.3

1)   [tex]\frac{1}{2}[/tex] × (14.8 + 5.2) (21.3)

Add the numbers in the parenthesis.

2)  [tex]\frac{1}{2}[/tex] × (20) (21.3)

Multiply the parenthesis.

3) [tex]\frac{1}{2}[/tex] × 426

Reduce the numbers with the greatest common factor: 2

4) 213

Answer:

1) 22/20 = 1.1

2) 18/15 = 1.2

3) No, because they both are different values and their slopes are different.

Answer:

Arc DE = 90°

m<GAB = 82°

Arc DC = 49°

Step-by-step explanation:

Given:

m<EAF = 74°

m<EAD = right angle = 90°

Arc BG = 82°

Required:

Arc DE,

<GAB, and

Arc DC

Solution:

Recall that the central angle measure = the intercepted arc measure.

Therefore:

✔️Arc DE = m<EAD

Arc DE = 90° (Substitution)

✔️m<GAB = arc BG

m<GAB = 82° (Substitution)

✔️Arc DC = m<CAD

Find m<CAD

m<CAD = ½(180 - m<GAB)

m<CAD = ½(180 - 82)

m<CAD = 49°

Arc DC = m<CAD

Arc DC = 49°
