Calculate the circumference of a semi circle which diameter is 28cm

Answer:$105

Step-by-step explanation:

I think but the way I done it was a 100 *1+5

Given:

32 and 28 are the two numbers.

To find:

(a) The GCF of 32 and 28.

(b) Using the GCF, find the factor of (32-28).

Solution:

(a)

The factor forms of the given numbers are:

[tex]32=2\times 2\times 2\times 2\times 2[/tex]

[tex]28=2\times 2\times 7[/tex]

It is clear that, 2 and 2 are the common factors in both.

[tex]GCF(32,28)=2\times 2[/tex]

[tex]GCF(32,28)=4[/tex]

Hence, the GCF of 32 and 28 is 4.

(b)

Using the GCF we need to find the factor of (32-28).

[tex]32-28=4\times 8-4\times 7[/tex]

Taking out the GCF, we get

[tex]32-28=4\times (8-7)[/tex]

Hence, [tex]32-28=4\times (8-7)[/tex].

Answer:

Relative max : -4

Relative min: -4.5

Step-by-step explanation:

You have to look at the graph and identity the max as the highest point that is an actual point and identity the min as the lowest point that is an actual point.

Step-by-step explanation:

Pls give brainliest!! Have a nice day!!

Answer:

40 meters and 2

Step-by-step explanation:

Answer:18

Step-by-step explanation:

Because 40% of 45 is 18

Given:

The expression is

[tex]9\sqrt{x}-3\sqrt{x}[/tex]

To find:

The result after subtracting the radicals.

Solution:

We have,

[tex]9\sqrt{x}-3\sqrt{x}[/tex]

We need to combine these terms.

Taking out common factors, we get

[tex]=(9-3)\sqrt{x}[/tex]

[tex]=6\sqrt{x}[/tex]

The result after subtracting the radicals is [tex]6\sqrt{x}[/tex].

Therefore, the correct option is B.

11=x

find AC:

AC= 11+3

AC=14

14 is your answer!!

Answer:

14 fleeces can be made from 280 large plastic bottles.

Step-by-step explanation:

Given that:

20 large plastic bottles can be recycled to make 1 fleece jacket.

Ratio of bottles to jacket = 20:1

Number of large plastic bottles = 280

Let,

x be the number of fleece jackets.

Ratio of large bottles to fleece jackets = 280 : x

This is a proportional relationship.

20 : 1 :: 280 : x

Product of mean = Product of extreme

280 = 20x

20x = 280

Dividing both sides by 20

[tex]\frac{20x}{20}=\frac{280}{20}\\x = 14[/tex]

Hence,

14 fleeces can be made from 280 large plastic bottles.

Answer:

n=1, m=3, and p=-4

Step-by-step explanation:

Take the fourth root of both sides

so x^n*y^m*z^p=x*y^3*z^-4;

notice z has a negative exponent because it was in the denominator

therefore, n=1, m=3, and p=-4

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

Explanation:

On that diagram, the unmarked angle above the (6x-8) is equal to (5x+12). This is because the unmarked angle and the angle marked with (5x+12) are corresponding angles. Corresponding angles must be congruent if you want line m to be parallel to line n.

From here we add up (5x+12) and (6x-8) and set that sum equal to 180. Solve for x

We get the following:

(5x+12)+(6x-8) = 180

5x+12+6x-8 = 180

(5x+6x)+(12-8) = 180

11x+4 = 180

11x = 180-4

11x = 176

x = 176/11

x = 16

Answer:

[tex]k=1\text{ or } k=4[/tex]

Step-by-step explanation:

We can use the Polynomial Remainder Theorem. It states that if we divide a polynomial P(x) by a binomial in the form (x - a), then our remainder will be P(a).

We are dividing:

[tex](x^2+5x+7)\div(x+k)[/tex]

So, a polynomial by a binomial factor.

Our factor is (x + k) or (x - (-k)). Using the form (x - a), our a = -k.

We want our remainder to be 3. So, P(a)=P(-k)=3.

Therefore:

[tex](-k)^2+5(-k)+7=3[/tex]

Simplify:

[tex]k^2-5k+7=3[/tex]

Solve for k. Subtract 3 from both sides:

[tex]k^2-5k+4=0[/tex]

Factor:

[tex](k-1)(k-4)=0[/tex]

Zero Product Property:

[tex]k-1=0\text{ or } k-4=0[/tex]

Solve:

[tex]k=1\text{ or } k=4[/tex]

So, either of the two expressions:

[tex](x^2+5x+7)\div(x+1)\text{ or } (x^2+5x+7)\div(x+4)[/tex]

Will yield 3 as the remainder.

Answer:

X = 43

Step-by-step explanation:

X + 2 = 45

X + 2 - 2 = 45 - 2

All you have to do is add 2 more to 43 and you'll get 45, so 43 is your answer.
