Please help me find the value of x

Answer:

≈ 13.1 cm²

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × [tex]\frac{60}{360}[/tex]

   = π × 5² × [tex]\frac{1}{6}[/tex]

   = 25π ÷ 6

   ≈ 13.1 cm² ( to 1 dec. place )

Answer:

area = 13.1 cm²

Step-by-step explanation:

area of sector formulae:

[tex] \frac{theta}{360} \times \pi {r}^{2} [/tex]

theta = 60°

radius = 5 cm

π = 22/7

substitute the values into the formulae

[tex] \frac{60}{360} \times \frac{22}{7} \times {5}^{2} [/tex]

[tex] \frac{1}{6} \times \frac{22}{7} \times 25[/tex]

[tex] \frac{1}{6} \times \frac{25 \times 22}{7} [/tex]

[tex] \frac{1}{6} \times \frac{550}{7} [/tex]

[tex] \frac{550 \times 1}{6 \times 7} [/tex]

[tex] \frac{550}{42} [/tex]

[tex]13.1 \: cm {}^{2} [/tex]

Answer:

6. Second choice, 51

7. Second choice, 3

Step-by-step explanation:

6. Multiply 255 with 1/5 = 255/5 = 51 times

7. 1/400 mutiply with 1200 = 1200/400 = 3

Step-by-step explanation:

even though it is not the only thing that has to do with it all in

Answer:

The other number is 20.

Step-by-step explanation:

[tex]\frac{10 + x}{2} = 15[/tex]

Multiply each side by 2.

[tex]10 + x = 30[/tex]

Subtract 10 from each side.

[tex]x = 20[/tex]

There you go!

Answer:

Both of them are correct.

The perimeter is found by adding up all four sides. If you notice, one of them is width and one of them is length. A rectangle has four sides, two width and two length.

l= length and w=width so P=2l+2w.

But, we can combine them by factorizing 2l+2w.

Lets see what we can pull out. We can only pull out 2.

2(l+w)=2l+2w.

2(l+w)=P

Both of them are correct.

Hope this helps plz hit the crown :D

Answer:

Greatest growth was between : year 3 and year 4

Percentage growth was about 32%

Step-by-step explanation:

Given the data:

Year : ______1 ____ 2 _____ 3 _______ 4

Students: __ 14 ___ 19 _____ 25 ______ 33

Number of students :

Year 1 & year 2 = 19 - 14 = 5

Year 2 & year 3 = 25 - 19 = 6

Year 3 & year 4 = 33 - 25 = 8

Hence,The two years at which the greatest growth was observed is between year 3 and year 4.

Percentage growth :

((33 - 25) / 25) * 100%

(8 / 25) * 100%

0.32 * 100%

= 32%

Step-by-step explanation:

(3 + 2i)(1 + iy)

= 3 + (3y + 2)i - 2y (because i² = -1)

For this to be real, (3y + 2) = 0. => y = -2/3

For this to be imaginary, y can be any real or complex number (except -2/3)

Step-by-step explanation:

Answer:

[tex]r=0.07[/tex]

Step-by-step explanation:

From the question we are told that

An offer of 2$ in 11 years on every dollar

Generally we make use of this formula

[tex]F=P(1+r/100)^t[/tex]

where

[tex]f=Future value[/tex]

[tex]P= present value[/tex]

[tex]r=Rate[/tex]

[tex]t=time[/tex]

Mathematically solving  for the rate

     [tex]2=1(1+r/100)^1^1[/tex]

    [tex](2)^1^/^1^1=(1+r/100)[/tex]

    [tex](1+r/100=1.0650[/tex]

     [tex]r=(1.0650-1) *100[/tex]

     [tex]r=0.07[/tex]

Generally this shows that the account give an annual rate of 0.07

Answer:

4/5

Step-by-step explanation:

32/40

Both can be divisible by 4

32 ÷ 4 = 8

40 ÷ 4 = 10

8/10

8 and 10 can be simplified again by 2

8 ÷ 2 = 4

10 ÷ 2 = 5

4/5

This cannot be simplified anymore, to check just divide.

32/40 = 0.8

4/5 = 0.8

The simplified form of 32/40 is 4/5.

To simplify the fraction 32/40, we can find the greatest common divisor (GCD) of the numerator (32) and denominator (40) and divide both by that value.

The GCD of 32 and 40 is 8. By dividing both the numerator and denominator by 8, we can simplify the fraction:

32 ÷ 8 = 4

40 ÷ 8 = 5

Therefore, the simplified form of 32/40 is 4/5.

3/2=x/1

3=2x

x=3/2

x=1.5

so the unit rate of price per melon is 1.5

Answer:

Step-by-step explanation:

unit rate is another way of saying  "slope of the line"

3/2 is the slope of the line..just from inspection of the graph

1.5  is another way to say  3/2  and that's how me might normally say the cost of one watermelon... it's a  $1.50 so the unit rate is 1.5 units.. and here the units are dollars

Answer:

The two expressions are;

1) -8 ft. + 3 × 6 ft. = 12 feet

2) -6 ft. + 2 × 5 ft. + 8 ft. = 12 feet

Step-by-step explanation:

The given parameters are;

The lengths in feet Cecil can travel = 5 feet, 6 feet, and 8 feet

The distances Cecil can travel forward = (positive 5, 6, 8)

Backwards Cecil can travel distances of (-5, -6, -8)

Cecil can go forward past the ladder and return back

Therefore, the number expressions by which Cecil can cross a tightrope 12 feet long are;

1) -8 ft. + 3 × 6 ft. = 12 feet

Which is to go back 8 feet and then to go forward 6 feet three times

2) -6 ft. + 2 × 5 ft. + 8 ft. = 12 feet

Which is to go back 6 feet then to go forward in 5 feet two times and then in forward again in 8 feet.
