Write the fraction 36/27 in simplest form

Answer:

they are directly proportional

so

5/22*7=1.59

he would finish in 1.59 min

Answer:

3sqrt2

Step-by-step explanation:

If a side length is a, then a^2 + a^2 = 36

2a^2 = 36

a^2 = 18

a = 3sqrt2

Or, you can remember that in a square, if you cut it in half diagonally, you get a 45-45-90 triangle, so the sidenglth is diagonal/sqrt2

Answer:

42 and a half

Step-by-step explanation:

17÷2 = 8.5x5= 42.5(42 and a half)

Answer:

42.5 hours

Step-by-step explanation:

If she spent 17 hours I’m 2 weeks and she practiced for 5 weeks, do 17 x 2 and you will get 34 the extra week 17/2 which is 8.5 add those 2 up and you get 42.5 hours she spent there (does that make sense? sorry if it doesn’t)

Answer:

8w

Step-by-step explanation:

Given that:

Length = l

Width = w

l = 3w

Perimeter of rectangular board :

Perimeter of a rectangle = 2(l + w)

Perimeter = 2(3w + w)

Perimeter = 2(4w)

Perimeter of rectangular board = 8w

Answer:

We get tₙ: [tex]\mathbf{t_n=an}[/tex]

10th term is [tex]t_{10}=10a[/tex]

Step-by-step explanation:

The given arithmetic sequence is: a,2a,3a

We need to find tₙ and tenth term

Finding tₙ

The formula used is: [tex]t_n=t1+(n-1)d[/tex]

We need to find d, the common difference

a₁ = a

a₂ = 2a

We can find common difference using the formula:

[tex]t_n=t_1+(n-1)d\\Put\:n=2\\t_2=t_1+(2-1)d\\2a=a+d\\d=2a-a\\d=a[/tex]

So, we get common difference d = a

Now, finding tₙ

[tex]t_n=t_1+(n-1)d\\t_n=a+(n-1)a\\t_n=a+an-a\\t_n=an[/tex]

So, we get tₙ: [tex]\mathbf{t_n=an}[/tex]

Now, finding 10th term

By putting n=10 in the equation [tex]t_n=an[/tex]

[tex]t_n=an\\Put\:n=10\\t_{10}=a(10)\\t_{10}=10a[/tex]

So, 10th term is 10a

Answer: x=8 and y=4

Step-by-step explanation:

x+y=12           x=12-y                     x=12-4

14x+22y=200                                x=8

14(12-y)+22y=200

168-14y+22y=200

-168                 -168

-14y+22y=32

8y=32

8y/8=32/8

y=4

Answer: −

-4x^2-5x+10

Step-by-step explanation:

Answer: -4x^2 -5x + 10

Step-by-step explanation:  

Simplify the expression.

Answer:

I think 3x doesn't belong because it is the only positive number.

I think -5x doesn't belong because it is the only one without a 3.

I think -3 doesn't belong because it is the only one without an x.

I think -3x² doesn't belong because it is the only one with an exponent.

Answer :

(1) The radius of a circle is 1.5 m.

(2) The diameter of a circle is 28 ft.

(3) The radius of a circle is 10 in.

(4) The circumference of circle is 47.14 m.

(5) The circumference of circle is 44 yd.

Step-by-step explanation :

Part 1:

Given: d = 3 m

Now we have to determine the radius of circle.

As we know that:

Radius of a circle = [tex]\frac{Diameter}{2}[/tex]

So,

Radius of a circle = [tex]\frac{3m}{2}=1.5m[/tex]

The radius of a circle is 1.5 m.

Part 2:

Given: r = 14 ft

Now we have to determine the diameter of circle.

As we know that:

Radius of a circle = [tex]\frac{Diameter}{2}[/tex]

So,

Diameter of a circle = [tex]Radius\times 2[/tex]

Diameter of a circle = [tex]14ft\times 2=28ft[/tex]

The diameter of a circle is 28 ft.

Part 3:

Given: d = 20 in

Now we have to determine the radius of circle.

As we know that:

Radius of a circle = [tex]\frac{Diameter}{2}[/tex]

So,

Radius of a circle = [tex]\frac{20in}{2}=10in[/tex]

The radius of a circle is 10 in.

Part 4:

Given: d = 15 m

Now we have to determine the circumference of circle.

Formula used:

[tex]C=\pi d[/tex]

where,

C = circumference

d = diameter

So,

[tex]C=\frac{22}{7}\times 15m[/tex]

[tex]C=47.14m[/tex]

The circumference of circle is 47.14 m.

Part 5:

Given: r = 7 yd

Now we have to determine the circumference of circle.

Formula used:

[tex]C=\pi d[/tex]

or we can write,

[tex]C=\pi (2\times r)[/tex]

where,

C = circumference

d = diameter

r = radius

So,

[tex]C=\frac{22}{7}\times (2\times 7yd)[/tex]

[tex]C=44yd[/tex]

The circumference of circle is 44 yd.

Step-by-step explanation:

[tex]4x + 7y = 41 \\ 4 \times ( - 7) + 7 \times ( - 16) = 41[/tex]

12e - 6f - 8

Step-by-step explanation:

(a+b)*c = a*c + b*c

6e * 2 -3f * 2 -4 * 2

Answer:

AB=8

Step-by-step explanation:

First, you get figure out x. Since both sides are equal, use the equation x+3=2x-2, then subtract x from both sides, 3=x-2, and then add 2 to both sides, x=5. Then use one of the equations to get the length of the side, I used x+3=8, which is your answer.

9514 1404 393

Answer:

Step-by-step explanation:

The missing side is found using the Pythagorean theorem:

  X = √(37^2 -22^2) = √885 ≈ 29.7 . . . feet

The missing angle is found using the cosine relation:

  Cos = Adjacent/Hypotenuse

  cos(x) = 22/37

  x = arccos(22/37) ≈ 53.5°

Answer:

13.5

Step-by-step explanation:

equilateral triangle (all sides are equal) thus, if one side is 4.5 u will need to take 4.5x3=13.5

Well let me help.

For the first Question, the question is asking for the perimeter of the plot so assuming the plot is a rectangle, the perimeter will be (2*3)+(2*4.3)

=6+8.6

=14.6km.

Question 2

The problem involves finding the perimeter of the triangular garden. since the garden is an equilateral triangle, the perimeter will be thrice the side given ("equilateral" means "equal sided triangle"). So the answer will be 3*4.5

= 13.5 km.

Question 3

Same type of question as Q2 but this type is isosceles triangle (only two equal sides with one being different)

So the perimeter will be (2*15)+20

=30+20

=50km.

I hope this'll help

Answer:

Answer:1.) I chose coin A and B

2.) Coin: B Value: $40 Annual rate: %5

Coin: A Value: $25 Annual rate: %7

3.) Coin: A P: 25 R: 1.07 Function: v = 25(1.07)^t

Coin: B P: 40 R: 1.05 Function: v = 40(1.05)^t

4.) Base: 1+r Initial: P Exponent: t

If R increased, then P would also increase because you must distribute, and you would be distributing R into P there for if R changes then so would P.

5.) Coin A: Initial value: $25 10 years: $25.70 20 Years: $26.40 30 years: $27.10 60 years: $29.20

Coin B: Initial value: $40 10 years: $40.50 20 years: $41 30 years: $41.50 60 years: $43

Coin C: Initial value: $60 10 years: $60.40 20 years: $60.80 30 years: $61.50 60 years: $62.40

6.) Coin A because the value goes up the most and I probably wouldn't be able to keep the coin for more than 60 years because I would lose it.

Answer:

5 DVD's

Step-by-step explanation:

So Basically It means the 25$ a month Plan is the same if you pay

5 DVD's

Ok each DVD costs 3$ and if you buy 5 of them you just bought 15 bucks worth of DVD's plus the membership which is 10$ in which the equation is

3(x)+10=25

X=5 by the way

So Basically it means if you Buy 5 DVD's plus the member ship thats the same money as the 25$ a month deal for unlimated DVD's

Simplified version: 5 DVD's

Answer:

You will have $623.3441462 in your account after 7 years

Step-by-step explanation:

The formula of the compounded interest is A = P [tex](1+\frac{r}{n})^{nt}[/tex] , where

∵ You are opening a savings account with $500  

∴ P = 500

∵ The bank offers 3.2% interest, compounded yearly

∴ r = 3.2% ⇒ divide it by 100 to change it to decimal

∴ r = 3.2 ÷ 100 = 0.032

∵ The interest is compounded yearly

∴ n = 1

∵ The time is 7 years

∴ t = 7

→ Substitute these values in the rule above to find A

∵ A = 500 [tex](1+\frac{0.032}{1})^{1(7)}[/tex]

∴ A = 500 [tex](1.032)^{7}[/tex]

∴ A = 623.3441462

∴ You will have $623.3441462 in your account after 7 years

x = 17 m

Step-by-step explanation:

The dimensions of the rectangular ceiling are 15 m by 8 m

We need to find the length of the string of lights need to be to reach from one corner of the ceiling to the opposite corner. Let it is x.

We need to find the diagonal of the rectangular ceiling. It can be calculated using Pythagoras theorem.

[tex]x^2=15^2+8^2\\\\x^2=225+64\\\\x^2=289\\\\x=\sqrt{289}\\\\x=17\ m[/tex]

So, the length of the string of lights is 17 m.
