Answer:8.99 cm

Step-by-step explanation:

Answer:

[tex]8.995[/tex]cm

Step-by-step explanation:

The circumference formula is: [tex]C=2\pi r[/tex]

We are given the circumference, which is 56.52cm.

The question wants us to find the radius, r.

To achieve this, we must solve for r.

Plugging in 56.52 for C we get:

[tex]56.52=2\pi r[/tex]

Dividing both sides by [tex]2\pi[/tex], we find r:[tex]8.995[/tex]

[tex]\frac{56.52}{2\pi } =r[/tex]

[tex]8.995[/tex]≈[tex]r[/tex]

If you want to round it up, you can round it to 9cm.

Answer:

5X²+7X-9-4X²-X+18

5X²-4X²+7X-X+18-9

X²+6X+9 =0

X²+(3X+3X)+(3×3)=0

ALL FACTORS ARE =3,3   that is  pdt of factor 3×3 =9   sum =3+3 =6

(X+3) ( X+3) =0  

X+3 =0

X=-3

ANS = X=-3

Answer:

2x=3

W+1.3=2.7

3y=5.1

z+1/3=1/2

Step-by-step explanation:

You just add up all on the left to equate that on the right

2x=3

W+1.3=2.7

3y=5.1

z+1/3=1/2

In case you have to solve:

x=3/2

W=2.4

y=1.7

z=1/6

Answer:

  (b)  120°

Step-by-step explanation:

The points on the figure are 120° apart, so each will replace the previous when the figure is rotated 120°.

The figure has 120° rotational symmetry.

__

That is also called "order 3 rotational symmetry" as there are three positions a point can be in that will make the figure look identical.

Answer:

B. 120 & D. 240 since they are both multiples of 120

Hi! The person who explained it before me helped but didn't give the exact answer so I just wanted to say what it was so nobody got confused.

Have a nice day and hope this helps! :)

Answer:

The answer should be 20,000 feet

Step-by-step explanation:

sin 0 =opposite/hypotenuse

sin 30 = AB/AC

sin 30 = 10000/c

c= 10000/sin 30

c=10000/1/2

c=20,000 feet

Answer:

48π

Step-by-step explanation:

Given that,

The radius of the sphere is increasing at a rate of 3cm/minute, [tex]\dfrac{dr}{dt}=3\ cm/minute[/tex]

The volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Differentiating both sides wrt t.

[tex]\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3r^2\times \dfrac{dr}{dt}\\\\=4\pi r^2\times \dfrac{dr}{dt}[/tex]

Put r = 2 cm and dr/dt = 3 cm/minute

So,

[tex]\dfrac{dV}{dt}=4\pi r^2\times \dfrac{dr}{dt}\\\\\dfrac{dV}{dt}=4\pi \times 2^2\times 3\\\\\dfrac{dV}{dt}=48\pi[/tex]

Hence, the correct option is (a) "48π".

We can see both terms have a (x-2) in them.

We can also see that 8 and 2 are both even so there is a 2 in common.

This means that the gcd or hcf or whatever you call it is 2(x-2)

**Just mentioning most of the time we call it the GCD(greatest common divisor) or the GCF(greatest common factor) and almost never uses hcf :)

Answer:

x = 2 ± √34/5

Step-by-step explanation:

Move terms to the left side.

5x^2 - 4x = 6

5x^2 - 4x -6 = 0

Identify a, b, and c before plugging them into the quadratic formula.

a = 5

b = -4

c = -6

x = -(-4) ± √(-4)^2 - 4 * 5(-6)/2 * 5

Then simplify.

(F*g)(x) means to multiply the two equations.

Multiply each term by each term:

2x-1 * 3x+5 =

2x * 3x + 2x*5 + (-1)*3x + (-1)*5 =

6x^2 + 10x -3x -5 =

6x^2+7x-5

Answer:

10 feet 5 inches long

Step-by-step explanation:

12 inches = 1 foot

11 inches + 6 inches = 17 inches = 1 foot 5 inches

1 foot 5 inches + 5 feet + 4 feet = 10 feet 5 inches

Therefore, the walking board is 10 feet 5 inches long

Answer:

0.4224 = 42.24% probability he will find an expired meter BEFORE the 3rd one

Step-by-step explanation:

For each car, there is a 24% probability that it had expired parking meters.

What is the probability he will find an expired meter BEFORE the 3rd one?

Three possible outcomes:

Two expired(each with 24% probability)

First expired(24% probability) and second not(76% probability)

First not(76% probability) and second expired(24% probability). So

[tex]p = 0.24^2 + 2*0.24*0.76 = 0.4224[/tex]

0.4224 = 42.24% probability he will find an expired meter BEFORE the 3rd one

Answer:

10 5/8

Step-by-step explanation:

17/1 x 5/8. Multiply numerators together and denominators you will get 85/8. Then you convert the improper fraction.

Answer:

10 5/8

Step-by-step explanation:

17 × 5/8  = 85/8

Simplify, sub-step b: Convert improper fraction to mixed number.

Convert improper fraction to mixed number

85 ÷ 8 = 10 remainder 5

85/8 = 10 5/8

Answer:

Answer:

[tex]Lengths: 93cm, 124cm, 62cm, 341cm, 150cm, 140cm[/tex]

[tex]Total := 910cm[/tex]

Step-by-step explanation:

Given

[tex]Lengths: 0.93m, 1.24m, 0.62m, 3.41m, 1.5m, 1.4m[/tex]

Required

Convert to length and calculate the total

To calculate to centimeters, we simply multiply each length to 100.

So, we have:

[tex]Lengths: 0.93m, 1.24m, 0.62m, 3.41m, 1.5m, 1.4m) * 100[/tex]

[tex]Lengths: 93cm, 124cm, 62cm, 341cm, 150cm, 140cm[/tex]

The total is:

[tex]Total := 93cm+ 124cm+ 62cm+ 341cm+ 150cm+ 140cm[/tex]

[tex]Total := 910cm[/tex]

Answer:

if    x ≥ 2, then y = x - 1

if    x < 2, then y = -x + 3

Step-by-step explanation:

y = 1* |x - 2|  +  1

y = |x-2| + 1

*** The rule on absolute value: |a| =a, if a ≥ 0; |a| = -a, if a < 0

If       x-2 ≥ 0,   then |x-2| = x-2, so y = (x - 2) + 1 = x - 1; y = x - 1

So   if    x ≥ 2, then y = x - 1

If      x-2 < 0,    then |x-2| = -(x-2) = -x + 2, so y =  {-x + 2} + 1 = -x + 3; y = -x + 3

So   if    x < 2, then y = -x + 3

Answer:

z=9

Step-by-step explanation:

we are given: 2/3z=6

we need to find what z is by itself

6 is 2/3rds of what the value of z is.

to find z, we need to multiply both sides by 3/2 (the reciprocal of 2/3z, to make the coefficient of 1)

3/2*2/3z=6*3/2

z=9

hope this helps :)

z = 9

Step-by-step explanation:

2/3 . z = 6

2z/3 = 6

Multiple all terms by the same value to eliminate fraction denominator,

3 x 2z/3 = 3 x 6

2z = 18 ( 3,3 got cancelled)

Divide both sides of the equation by the same term,

2z/2 = 18/2

On Simplify,

z = 9.

*(2,2 gets cancelled and 18/2 = 9)
